-
-## Version 7.3

- - new keywords in Perl (by [Kirk Kimmel][kk])
- - big Ruby syntax update (by [Vasily Polovnyov][vast])
- - small fixes in Bash
-
-- Also Oleg Efimov did a great job of moving all the docs for language and style
- developers and contributors from the old wiki under the source code in the
- "docs" directory. Now these docs are nicely presented at
- .

-
-## Version 7.2
-
-A regular bug-fix release without any significant new features. Enjoy!
-
-
-## Version 7.1
-
-A Summer crop:
-
-- [Marc Fornos][mf] made the definition for Clojure along with the matching
- style Rainbow (which, of course, works for other languages too).
-- CoffeeScript support continues to improve getting support for regular
- expressions.
-- Yoshihide Jimbo ported to highlight.js [five Tomorrow styles][tm] from the
- [project by Chris Kempson][tm0].
-- Thanks to [Casey Duncun][cd] the library can now be built in the popular
- [AMD format][amd].
-- And last but not least, we've got a fair number of correctness and consistency
- fixes, including a pretty significant refactoring of Ruby.

-
-
-## Version 7.0
-
-The reason for the new major version update is a global change of keyword syntax
-which resulted in the library getting smaller once again. For example, the
-hosted build is 2K less than at the previous version while supporting two new
-languages.
-
-Notable changes:
-
-- The library now works not only in a browser but also with [node.js][]. It is
- installable with `npm install highlight.js`. [API][] docs are available on our
- wiki.
-
-- The new unique feature (apparently) among syntax highlighters is highlighting
- *HTTP* headers and an arbitrary language in the request body. The most useful
- languages here are *XML* and *JSON* both of which highlight.js does support.
- Here's [the detailed post][p] about the feature.
-
-- Two new style themes: a dark "south" *[Pojoaque][]* by Jason Tate and an
- emulation of*XCode* IDE by [Angel Olloqui][ao].
-
-- Three new languages: *D* by [Aleksandar Ružičić][ar], *R* by [Joe Cheng][jc]
- and *GLSL* by [Sergey Tikhomirov][st].
-
-- *Nginx* syntax has become a million times smaller and more universal thanks to
- remaking it in a more generic manner that doesn't require listing all the
- directives in the known universe.
-
-- Function titles are now highlighted in *PHP*.
-
-- *Haskell* and *VHDL* were significantly reworked to be more rich and correct
- by their respective maintainers [Jeremy Hull][sr] and [Igor Kalnitsky][ik].
-
-And last but not least, many bugs have been fixed around correctness and
-language detection.
-
-Overall highlight.js currently supports 51 languages and 20 style themes.

-## Version 6.2
-
-A lot of things happened in highlight.js since the last version! We've got nine
-new contributors, the discussion group came alive, and the main branch on GitHub
-now counts more than 350 followers. Here are most significant results coming
-from all this activity:
-
-- 5 (five!) new languages: Rust, ActionScript, CoffeeScript, MatLab and
- experimental support for markdown. Thanks go to [Andrey Vlasovskikh][av],
- [Alexander Myadzel][am], [Dmytrii Nagirniak][dn], [Oleg Efimov][oe], [Denis
- Bardadym][db] and [John Crepezzi][jc].
-
-- 2 new style themes: Monokai by [Luigi Maselli][lm] and stylistic imitation of
- another well-known highlighter Google Code Prettify by [Aahan Krish][ak].
-
-- A vast number of [correctness fixes and code refactorings][log], mostly made
- by [Oleg Efimov][oe] and [Evgeny Stepanischev][es].

-## Version 6.1 — Solarized
-
-[Jeremy Hull][jh] has implemented my dream feature — a port of [Solarized][]
-style theme famous for being based on the intricate color theory to achieve
-correct contrast and color perception. It is now available for highlight.js in
-both variants — light and dark.
-
-This version also adds a new original style Arta. Its author pumbur maintains a
-[heavily modified fork of highlight.js][pb] on GitHub.

-
-
-## Version 6.0
-
-New major version of the highlighter has been built on a significantly
-refactored syntax. Due to this it's even smaller than the previous one while
-supporting more languages!
-
-New languages are:
-
-- Haskell by [Jeremy Hull][sourrust]
-- Erlang in two varieties — module and REPL — made collectively by [Nikolay
- Zakharov][desh], [Dmitry Kovega][arhibot] and [Sergey Ignatov][ignatov]
-- Objective C by [Valerii Hiora][vhbit]
-- Vala by [Antono Vasiljev][antono]
-- Go by [Stephan Kountso][steplg]

-[ignatov]: https://github.com/ignatov
-[vhbit]: https://github.com/vhbit
-[antono]: https://github.com/antono
-[steplg]: https://github.com/steplg
-
-Also this version is marginally faster and fixes a number of small long-standing
-bugs.
-
-Developer overview of the new language syntax is available in a [blog post about
-recent beta release][beta].
-
-[beta]: http://softwaremaniacs.org/blog/2011/04/25/highlight-js-60-beta/en/
-
-P.S. New version is not yet available on a Yandex CDN, so for now you have to
-download [your own copy][d].
-
-[d]: /soft/highlight/en/download/
-
-
-## Version 5.14
-
-Fixed bugs in HTML/XML detection and relevance introduced in previous
-refactoring.
-
-Also test.html now shows the second best result of language detection by
-relevance.
-
-
-## Version 5.13
-
-Past weekend began with a couple of simple additions for existing languages but
-ended up in a big code refactoring bringing along nice improvements for language
-developers.
-
-### For users
-
-- Description of C++ has got new keywords from the upcoming [C++ 0x][] standard.
-- Description of HTML has got new tags from [HTML 5][].
-- CSS-styles have been unified to use consistent padding and also have lost
- pop-outs with names of detected languages.
-- [Igor Kalnitsky][ik] has sent two new language descriptions: CMake & VHDL.
-
-This makes total number of languages supported by highlight.js to reach 35.
-
-Bug fixes:
-
-- Custom classes on `` tags are not being overridden anymore
-- More correct highlighting of code blocks inside non-`` containers:
- highlighter now doesn't insist on replacing them with its own container and
- just replaces the contents.
-- Small fixes in browser compatibility and heuristics.
-
-[c++ 0x]: http://ru.wikipedia.org/wiki/C%2B%2B0x
-[html 5]: http://en.wikipedia.org/wiki/HTML5
-[ik]: http://kalnitsky.org.ua/
-
-### For developers
-
-The most significant change is the ability to include language submodes right
-under `contains` instead of defining explicit named submodes in the main array:
-
- contains: [
- 'string',
- 'number',
- {begin: '\\n', end: hljs.IMMEDIATE_RE}
- ]
-
-This is useful for auxiliary modes needed only in one place to define parsing.
-Note that such modes often don't have `className` and hence won't generate a
-separate `` in the resulting markup. This is similar in effect to
-`noMarkup: true`. All existing languages have been refactored accordingly.
-
-Test file test.html has at last become a real test. Now it not only puts the
-detected language name under the code snippet but also tests if it matches the
-expected one. Test summary is displayed right above all language snippets.
-
-
-## CDN
-
-Fine people at [Yandex][] agreed to host highlight.js on their big fast servers.

-
-
-## Version 5.10 — "Paris".
-
-Though I'm on a vacation in Paris, I decided to release a new version with a
-couple of small fixes:
-
-- Tomas Vitvar discovered that TAB replacement doesn't always work when used
- with custom markup in code
-- SQL parsing is even more rigid now and doesn't step over SmallTalk in tests
-
-
-## Version 5.9
-
-A long-awaited version is finally released.
-
-New languages:
-
-- Andrew Fedorov made a definition for Lua
-- a long-time highlight.js contributor [Peter Leonov][pl] made a definition for
- Nginx config
-- [Vladimir Moskva][vm] made a definition for TeX
-
-[pl]: http://kung-fu-tzu.ru/
-[vm]: http://fulc.ru/
-
-Fixes for existing languages:
-
-- [Loren Segal][ls] reworked the Ruby definition and added highlighting for
- [YARD][] inline documentation
-- the definition of SQL has become more solid and now it shouldn't be overly
- greedy when it comes to language detection
-
-[ls]: http://gnuu.org/
-[yard]: http://yardoc.org/
-
-The highlighter has become more usable as a library allowing to do highlighting
-from initialization code of JS frameworks and in ajax methods (see.
-readme.eng.txt).
-
-Also this version drops support for the [WordPress][wp] plugin. Everyone is
-welcome to [pick up its maintenance][p] if needed.
-
-[wp]: http://wordpress.org/
-[p]: http://bazaar.launchpad.net/~isagalaev/+junk/highlight/annotate/342/src/wp_highlight.js.php
-
-
-## Version 5.8
-
-- Jan Berkel has contributed a definition for Scala. +1 to hotness!
-- All CSS-styles are rewritten to work only inside `` tags to avoid
- conflicts with host site styles.
-
-
-## Version 5.7.
-
-Fixed escaping of quotes in VBScript strings.
-
-
-## Version 5.5
-
-This version brings a small change: now .ini-files allow digits, underscores and
-square brackets in key names.
-
-
-## Version 5.4
-
-Fixed small but upsetting bug in the packer which caused incorrect highlighting
-of explicitly specified languages. Thanks to Andrew Fedorov for precise
-diagnostics!
-
-
-## Version 5.3
-
-The version to fulfil old promises.
-
-The most significant change is that highlight.js now preserves custom user
-markup in code along with its own highlighting markup. This means that now it's
-possible to use, say, links in code. Thanks to [Vladimir Dolzhenko][vd] for the
-[initial proposal][1] and for making a proof-of-concept patch.
-
-Also in this version:
-
-- [Vasily Polovnyov][vp] has sent a GitHub-like style and has implemented
- support for CSS @-rules and Ruby symbols.
-- Yura Zaripov has sent two styles: Brown Paper and School Book.
-- Oleg Volchkov has sent a definition for [Parser 3][p3].

-
-## Version 5.2
-
-- at last it's possible to replace indentation TABs with something sensible
- (e.g. 2 or 4 spaces)
-- new keywords and built-ins for 1C by Sergey Baranov
-- a couple of small fixes to Apache highlighting
-
-
-## Version 5.1
-
-This is one of those nice version consisting entirely of new and shiny
-contributions!
-
-- [Vladimir Ermakov][vooon] created highlighting for AVR Assembler
-- [Ruslan Keba][rukeba] created highlighting for Apache config file. Also his
- original visual style for it is now available for all highlight.js languages
- under the name "Magula".
-- [Shuen-Huei Guan][drake] (aka Drake) sent new keywords for RenderMan
- languages. Also thanks go to [Konstantin Evdokimenko][ke] for his advice on
- the matter.

-[drake]: http://drakeguan.org/
-[ke]: http://k-evdokimenko.moikrug.ru/
-
-
-## Version 5.0
-
-The main change in the new major version of highlight.js is a mechanism for
-packing several languages along with the library itself into a single compressed
-file. Now sites using several languages will load considerably faster because
-the library won't dynamically include additional files while loading.
-
-Also this version fixes a long-standing bug with Javascript highlighting that
-couldn't distinguish between regular expressions and division operations.
-
-And as usually there were a couple of minor correctness fixes.
-
-Great thanks to all contributors! Keep using highlight.js.
-
-
-## Version 4.3
-
-This version comes with two contributions from [Jason Diamond][jd]:
-
-- language definition for C# (yes! it was a long-missed thing!)
-- Visual Studio-like highlighting style
-
-Plus there are a couple of minor bug fixes for parsing HTML and XML attributes.
-
-[jd]: http://jason.diamond.name/weblog/
-
-
-## Version 4.2
-
-The biggest news is highlighting for Lisp, courtesy of Vasily Polovnyov. It's
-somewhat experimental meaning that for highlighting "keywords" it doesn't use
-any pre-defined set of a Lisp dialect. Instead it tries to highlight first word
-in parentheses wherever it makes sense. I'd like to ask people programming in
-Lisp to confirm if it's a good idea and send feedback to [the forum][f].
-
-Other changes:
-
-- Smalltalk was excluded from DEFAULT_LANGUAGES to save traffic
-- [Vladimir Epifanov][voldmar] has implemented javascript style switcher for
- test.html
-- comments now allowed inside Ruby function definition
-- [MEL][] language from [Shuen-Huei Guan][drake]
-- whitespace now allowed between `` and ``
-- better auto-detection of C++ and PHP
-- HTML allows embedded VBScript (`<% .. %>`)

-[voldmar]: http://voldmar.ya.ru/
-[mel]: http://en.wikipedia.org/wiki/Maya_Embedded_Language
-[drake]: http://drakeguan.org/
-
-
-## Version 4.1
-
-Languages:
-
-- Bash from Vah
-- DOS bat-files from Alexander Makarov (Sam)
-- Diff files from Vasily Polovnyov
-- Ini files from myself though initial idea was from Sam
-
-Styles:
-
-- Zenburn from Vladimir Epifanov, this is an imitation of a
- [well-known theme for Vim][zenburn].
-- Ascetic from myself, as a realization of ideals of non-flashy highlighting:
- just one color in only three gradations :-)
-
-In other news. [One small bug][bug] was fixed, built-in keywords were added for
-Python and C++ which improved auto-detection for the latter (it was shame that
-[my wife's blog][alenacpp] had issues with it from time to time). And lastly
-thanks go to Sam for getting rid of my stylistic comments in code that were
-getting in the way of [JSMin][].

-
-
-## Version 4.0
-
-New major version is a result of vast refactoring and of many contributions.
-
-Visible new features:
-
-- Highlighting of embedded languages. Currently is implemented highlighting of
- Javascript and CSS inside HTML.
-- Bundled 5 ready-made style themes!
-
-Invisible new features:
-
-- Highlight.js no longer pollutes global namespace. Only one object and one
- function for backward compatibility.
-- Performance is further increased by about 15%.
-
-Changing of a major version number caused by a new format of language definition
-files. If you use some third-party language files they should be updated.
-
-
-## Version 3.5
-
-A very nice version in my opinion fixing a number of small bugs and slightly
-increased speed in a couple of corner cases. Thanks to everybody who reports
-bugs in he [forum][f] and by email!
-
-There is also a new language — XML. A custom XML formerly was detected as HTML
-and didn't highlight custom tags. In this version I tried to make custom XML to
-be detected and highlighted by its own rules. Which by the way include such
-things as CDATA sections and processing instructions (` ... ?>`).
-
-[f]: http://softwaremaniacs.org/forum/viewforum.php?id=6
-
-
-## Version 3.3
-
-[Vladimir Gubarkov][xonix] has provided an interesting and useful addition.
-File export.html contains a little program that shows and allows to copy and
-paste an HTML code generated by the highlighter for any code snippet. This can
-be useful in situations when one can't use the script itself on a site.
-
-
-[xonix]: http://xonixx.blogspot.com/
-
-
-## Version 3.2 consists completely of contributions:
-
-- Vladimir Gubarkov has described SmallTalk
-- Yuri Ivanov has described 1C
-- Peter Leonov has packaged the highlighter as a Firefox extension
-- Vladimir Ermakov has compiled a mod for phpBB
-
-Many thanks to you all!
-
-
-## Version 3.1
-
-Three new languages are available: Django templates, SQL and Axapta. The latter
-two are sent by [Dmitri Roudakov][1]. However I've almost entirely rewrote an
-SQL definition but I'd never started it be it from the ground up :-)
-
-The engine itself has got a long awaited feature of grouping keywords
-("keyword", "built-in function", "literal"). No more hacks!
-
-[1]: http://roudakov.ru/
-
-
-## Version 3.0
-
-It is major mainly because now highlight.js has grown large and has become
-modular. Now when you pass it a list of languages to highlight it will
-dynamically load into a browser only those languages.
-
-Also:
-
-- Konstantin Evdokimenko of [RibKit][] project has created a highlighting for
- RenderMan Shading Language and RenderMan Interface Bytestream. Yay for more
- languages!
-- Heuristics for C++ and HTML got better.
-- I've implemented (at last) a correct handling of backslash escapes in C-like
- languages.
-
-There is also a small backwards incompatible change in the new version. The
-function initHighlighting that was used to initialize highlighting instead of
-initHighlightingOnLoad a long time ago no longer works. If you by chance still
-use it — replace it with the new one.
-
-[RibKit]: http://ribkit.sourceforge.net/
-
-
-## Version 2.9
-
-Highlight.js is a parser, not just a couple of regular expressions. That said
-I'm glad to announce that in the new version 2.9 has support for:
-
-- in-string substitutions for Ruby -- `#{...}`
-- strings from from numeric symbol codes (like #XX) for Delphi
-
-
-## Version 2.8
-
-A maintenance release with more tuned heuristics. Fully backwards compatible.
-
-
-## Version 2.7
-
-- Nikita Ledyaev presents highlighting for VBScript, yay!
-- A couple of bugs with escaping in strings were fixed thanks to Mickle
-- Ongoing tuning of heuristics
-
-Fixed bugs were rather unpleasant so I encourage everyone to upgrade!
-
-
-## Version 2.4
-
-- Peter Leonov provides another improved highlighting for Perl
-- Javascript gets a new kind of keywords — "literals". These are the words
- "true", "false" and "null"
-
-Also highlight.js homepage now lists sites that use the library. Feel free to
-add your site by [dropping me a message][mail] until I find the time to build a
-submit form.
-
-[mail]: mailto:Maniac@SoftwareManiacs.Org
-
-
-## Version 2.3
-
-This version fixes IE breakage in previous version. My apologies to all who have
-already downloaded that one!
-
-
-## Version 2.2
-
-- added highlighting for Javascript
-- at last fixed parsing of Delphi's escaped apostrophes in strings
-- in Ruby fixed highlighting of keywords 'def' and 'class', same for 'sub' in
- Perl
-
-
-## Version 2.0
-
-- Ruby support by [Anton Kovalyov][ak]
-- speed increased by orders of magnitude due to new way of parsing
-- this same way allows now correct highlighting of keywords in some tricky
- places (like keyword "End" at the end of Delphi classes)
-
-[ak]: http://anton.kovalyov.net/
-
-
-## Version 1.0
-
-Version 1.0 of javascript syntax highlighter is released!
-
-It's the first version available with English description. Feel free to post
-your comments and question to [highlight.js forum][forum]. And don't be afraid
-if you find there some fancy Cyrillic letters -- it's for Russian users too :-)

-# Highlight.js
-
-[](https://travis-ci.org/isagalaev/highlight.js)
-
-Highlight.js is a syntax highlighter written in JavaScript. It works in
-the browser as well as on the server. It works with pretty much any
-markup, doesn’t depend on any framework and has automatic language
-detection.
-
-## Getting Started
-
-The bare minimum for using highlight.js on a web page is linking to the
-library along with one of the styles and calling
-[`initHighlightingOnLoad`][1]:
-
-```html
-
-
-
-```
-
-This will find and highlight code inside of `` tags; it tries
-to detect the language automatically. If automatic detection doesn’t
-work for you, you can specify the language in the `class` attribute:
-
-```html
-...
-```
-
-The list of supported language classes is available in the [class
-reference][2]. Classes can also be prefixed with either `language-` or
-`lang-`.
-
-To disable highlighting altogether use the `nohighlight` class:
-
-```html
-...
-```
-
-## Custom Initialization
-
-When you need a bit more control over the initialization of
-highlight.js, you can use the [`highlightBlock`][3] and [`configure`][4]
-functions. This allows you to control *what* to highlight and *when*.
-
-Here’s an equivalent way to calling [`initHighlightingOnLoad`][1] using
-jQuery:
-
-```javascript
-$(document).ready(function() {
- $('pre code').each(function(i, block) {
- hljs.highlightBlock(block);
- });
-});
-```
-
-You can use any tags instead of `` to mark up your code. If
-you don't use a container that preserve line breaks you will need to
-configure highlight.js to use the ` ` tag:
-
-```javascript
-hljs.configure({useBR: true});
-
-$('div.code').each(function(i, block) {
- hljs.highlightBlock(block);
-});
-```
-
-For other options refer to the documentation for [`configure`][4].
-
-
-## Web Workers
-
-You can run highlighting inside a web worker to avoid freezing the browser
-window while dealing with very big chunks of code.
-
-In your main script:
-
-```javascript
-addEventListener('load', function() {
- var code = document.querySelector('#code');
- var worker = new Worker('worker.js');
- worker.onmessage = function(event) { code.innerHTML = event.data; }
- worker.postMessage(code.textContent);
-})
-```
-
-In worker.js:
-
-```javascript

-
-## Getting the Library
-
-You can get highlight.js as a hosted, or custom-build, browser script or
-as a server module. Right out of the box the browser script supports
-both AMD and CommonJS, so if you wish you can use RequireJS or
-Browserify without having to build from source. The server module also
-works perfectly fine with Browserify, but there is the option to use a
-build specific to browsers rather than something meant for a server.
-Head over to the [download page][5] for all the options.
-
-**Don't link to GitHub directly.** The library is not supposed to work straight
-from the source, it requires building. If none of the pre-packaged options
-work for you refer to the [building documentation][6].
-
-**The CDN-hosted package doesn't have all the languages.** Otherwise it'd be
-too big. If you don't see the language you need in the ["Common" section][5],
-it can be added manually:
-
-```html
-
-```
-
-**On Almond.** You need to use the optimizer to give the module a name. For
-example:
-
-```
-r.js -o name=hljs paths.hljs=/path/to/highlight out=highlight.js
-```
-

-# Highlight.js
-
-Highlight.js — это инструмент для подсветки синтаксиса, написанный на JavaScript. Он работает
-и в браузере, и на сервере. Он работает с практически любой HTML разметкой, не
-зависит от каких-либо фреймворков и умеет автоматически определять язык.
-
-
-## Начало работы
-
-Минимум, что нужно сделать для использования highlight.js на веб-странице — это
-подключить библиотеку, CSS-стили и вызывать [`initHighlightingOnLoad`][1]:
-
-```html
-
-
-
-```
-
-Библиотека найдёт и раскрасит код внутри тегов ``, попытавшись
-автоматически определить язык. Когда автоопределение не срабатывает, можно явно
-указать язык в атрибуте class:
-
-```html
-...
-```
-
-Список поддерживаемых классов языков доступен в [справочнике по классам][2].
-Класс также можно предварить префиксами `language-` или `lang-`.
-
-Чтобы отключить подсветку для какого-то блока, используйте класс `nohighlight`:
-
-```html
-...
-```
-
-## Инициализация вручную
-
-Чтобы иметь чуть больше контроля за инициализацией подсветки, вы можете
-использовать функции [`highlightBlock`][3] и [`configure`][4]. Таким образом
-можно управлять тем, *что* и *когда* подсвечивать.
-
-Вот пример инициализации, эквивалентной вызову [`initHighlightingOnLoad`][1], но
-с использованием jQuery:
-
-```javascript
-$(document).ready(function() {
- $('pre code').each(function(i, block) {
- hljs.highlightBlock(block);
- });
-});
-```
-
-Вы можете использовать любые теги разметки вместо ``. Если
-используете контейнер, не сохраняющий переводы строк, вам нужно сказать
-highlight.js использовать для них тег ` `:
-
-```javascript
-hljs.configure({useBR: true});
-
-$('div.code').each(function(i, block) {
- hljs.highlightBlock(block);
-});
-```
-
-Другие опции можно найти в документации функции [`configure`][4].
-
-
-## Web Workers
-
-Подсветку можно запустить внутри web worker'а, чтобы окно
-браузера не подтормаживало при работе с большими кусками кода.
-
-В основном скрипте:
-
-```javascript
-addEventListener('load', function() {
- var code = document.querySelector('#code');
- var worker = new Worker('worker.js');
- worker.onmessage = function(event) { code.innerHTML = event.data; }
- worker.postMessage(code.textContent);
-})
-```
-
-В worker.js:
-
-```javascript
-onmessage = function(event) {
- importScripts('/highlight.pack.js');
- var result = self.hljs.highlightAuto(event.data);
- postMessage(result.value);
-}
-```
-
-
-## Установка библиотеки
-
-Highlight.js можно использовать в браузере прямо с CDN хостинга или скачать
-индивидуальную сборку, а также установив модуль на сервере. На
-[странице загрузки][5] подробно описаны все варианты.
-
-**Не подключайте GitHub напрямую.** Библиотека не предназначена для
-использования в виде исходного кода, а требует отдельной сборки. Если вам не
-подходит ни один из готовых вариантов, читайте [документацию по сборке][6].
-
-**Файл на CDN содержит не все языки.** Иначе он будет слишком большого размера.
-Если нужного вам языка нет в [категории "Common"][5], можно дообавить его
-вручную:
-
-```html
-
-```
-
-**Про Almond.** Нужно задать имя модуля в оптимизаторе, например:
-
-```
-r.js -o name=hljs paths.hljs=/path/to/highlight out=highlight.js
-```

-PureBASIC native IDE style ( version 1.0 - April 2016 )
-
-by Tristano Ajmone
-
-Public Domain
-
-NOTE_1: PureBASIC code syntax highlighting only applies the following classes:
- .hljs-comment
- .hljs-function
- .hljs-keywords
- .hljs-string
- .hljs-symbol
-
- Other classes are added here for the benefit of styling other languages with the look and feel of PureBASIC native IDE style.
- If you need to customize a stylesheet for PureBASIC only, remove all non-relevant classes -- PureBASIC-related classes are followed by
- a "--- used for PureBASIC ... ---" comment on same line.
-
-NOTE_2: Color names provided in comments were derived using "Name that Color" online tool:

-VinylDNS: Portal Configuration Guide Portal Configuration Guide
-The portal configuration is much smaller than the API Server.
-

-Configuration
-
-
-Database Configuration
-VinylDNS supports both DynamoDB and MySQL backends (see API Database Configuration ).
-
-If using DynamoDB, follow the AWS DynamoDB Setup Guide first to get the values you need to configure here.
-
-If using MySQL, follow the MySQL Setup Guide first to get the values you need to configure here.
-
-The Portal uses the following tables:
-
-
-
-Note that the user table is shared between the API and the portal, and must be configured with
-the same values in both configs:
-

-LDAP configuration connects VinylDNS to your Directory where user information is stored.
-
-The default value for user sync enabled is false and user sync hours polling interval is 24 (max value). If the hours polling interval
-is configured higher than 24, 24 hours will be used.

-Cryptography Settings
-The Portal encrypts user secrets at rest using the same mechanism as the API server.
-
-Note: It is extremely important that these settings match the API server, otherwise the API server will not
-be able to decrypt user secrets and your installation will fail!
-
-Cryptography is pluggable , meaning you can bring your own crypto with you. All that is required is to provide an
-implementation of CryptoAlgebra
-using a crypto library of choice. The default implementation is NoOpCrypto
, which does not do any encryption (not recommended for production).
-
-The following are the configuration settings for crypto. Notice here the only thing we see is the type
. The type
-is the fully qualified class name for the CryptoAlgebra
you will be using. If your crypto implementation requires
-additional settings, they will be configured inside the crypto
element, adjacent to the type
.
-
-crypto {
- type = "vinyldns.core.crypto.JavaCrypto"
- secret = "8B06A7F3BC8A2497736F1916A123AA40E88217BE9264D8872597EF7A6E5DCE61"
-}
-
-
-
-Custom Links
-Custom links display either on the nav bar once logged in, or on the log in screen. These links are useful to point
-to internal documentation and procedures. For example, how to raise certain tickets with engineering, or
-internal slack channels.
-
-# an array of links

- # indicates that this link should be display on the sidebar once logged in
- displayOnSidebar = true

-play.http.secret.key = "vinyldnsportal-change-this-for-production"
-
-
-
-Test Login
-The test login should not be used for production environments. It is useful to tinker with VinylDNS. If this

-VinylDNS: Pre-requisites VinylDNS Pre-requisites
-VinylDNS has the following external requirements that need to be setup so that VinylDNS can operate. Those include:
-
-
- DNS - your DNS servers VinylDNS will interact with
- Database - the database houses all of VinylDNS information including history, records, zones, and users
- Message Queue - the message queue supports high-availability and throttling of commands to DNS backend servers
- LDAP - ldap supports both authentication as well as the source of truth for users that are managed inside the VinylDNS database
-
-
-DNS
-VinylDNS is not a DNS , rather it integrates with your existing DNS installations to enable DNS self-service and streamline
-DNS operations.
-
-VinylDNS communicates to your DNS via:
-
- DDNS
- DDNS is used for all record updates
- AXFR
- Zone Transfers are used to load DNS records into the VinylDNS database.
-
-
-VinylDNS communicates to your DNS using “connections”. A connection allows you to specify:
-
- The TSIG key name
- The TSIG key secret
- The server (and optionally port) to communicate to DNS with
-
-
-There are 2 connections, one for DDNS and another for zone transfers. This allows you to use a different DNS server / key
-for zone transfers.
-
-Connections (DDNS and Transfer) can be setup
-
- per zone
- every zone can override the global default by specifying its own connections.
- global default
- assuming you are managing a primary system, you can configure default zone connections .
-When no zone connection is specified on a zone, the global defaults will be used.
-
-
-Database
-
-The VinylDNS database has a NoSQL
/ non-relational design to it. Instead of having a heavily normalized set of SQL tables
-that surface in the system, VinylDNS relies on Repositories
where each Repository
is independent of each one another.
-This allows implementers to best map each Repository
into the data-store of choice.
-
-As Repositories
are independent, there are no “transactions” that span repositories. Each Repository
implementation
-can choose to use transactions if it maps to multiple tables within itself.
-
-There are links across repositories, for example the RecordSet.id
would be referenced in a RecordSetChangeRepository
.
-
-The following are the repositories presently used by VinylDNS:
-
-
- RecordSetRepository
- Instead of individual DNS records, VinylDNS works at the RRSet
. The unique key for RecordSet is
-the record name
+ record type
- RecordChangeRepository
- The history of all changes to all records in VinylDNS. In general, some kind of pruning strategy
-should be implemented otherwise this could get quite large
- ZoneRepository
- DNS Zones and managing access to zones
- ZoneChangeRepository
- The history of all changes made to zones in VinylDNS. Zone changes can including syncs,
-updating ACL rules, changing zone ownership, etc.
- GroupRepository
- VinylDNS Groups
- UserRepository
- VinylDNS Users. These users are typically created the first time the user logs into the portal.
-The user information will be pulled from LDAP, and inserted into the VinylDNS UserRepository
- MembershipRepository
- Holds a link from users to groups
- GroupChangeRepository
- Holds changes to groups and membership
- BatchChangeRepository
- VinylDNS allows users to submit multiple record changes across DNS zones at the same time within a Batch
-The BatchChangeRepository
holds the batch itself and all individual changes that executed in the batch.
- UserChangeRepository
- Holds changes to users. Currently only used in the portal.
-
-
-Database Types
-MySQL
-VinylDNS has implemented MySQL for all repositories so a MySQL-only instance of VinylDNS is possible. Furthermore, there are two
-repositories that have only been implemented in MySQL:
-
-
- ZoneRepository
- BatchChangeRepository
-
-
-Originally, the ZoneRepository
lived in DynamoDB. However, the access controls in VinylDNS made it very difficult
-to use DynamoDB as the query interface is limited. A SQL interface with JOIN
s was required.
-
-It should also be noted that all of the repositories have also been implemented in MySQL despite most currently running
-in DynamoDB in our VinylDNS instance.
-
-Review the Setup MySQL Guide for more information.
-
-AWS DynamoDB
-VinylDNS has gone through several architecture evolutions. Along the way, DynamoDB was chosen as the data store due to
-the volume of data at Comcast. It is an excellent key-value store with extremely high performance characteristics.
-
-VinylDNS has implemented DynamoDB for the following repositories:
-
-
- RecordSetRepository
- RecordChangeRepository
- ZoneChangeRepository
- GroupRepository
- UserRepository
- MembershipRepository
- GroupChangeRepository
- UserChangeRepository
-
-
-Currently using DynamoDB would also require the user to either use MySQL for the batch change and zone repositories or also provide
-an implementation for those repositories in a different data store.
-
-Review the Setup AWS DynamoDB Guide for more information.
-
-Message Queues
-Most operations that take place in VinylDNS use a message queue. These operations require high-availability, fault-tolerance
-with retry, and throttling. The message queue supports these characteristics in VinylDNS.
-
-Some operations do not use the message queue, these include user and group changes as they do not carry the same
-fault-tolerance and throttling requirements.
-
-Message Queue Types
-AWS SQS
-Our VinylDNS instance uses AWS SQS to fulfill its message queue service needs. SQS has the following characteristics:
-
-
- High-Availability
- Retry - in the event that a message cannot be processed, or if a node fails midstream processing, it will be automatically
-made available for another node to process
- Back-pressure - SQS is a pull based system, meaning that if VinylDNS is currently busy, new messages will not be pulled for processing.
-As soon as a node becomes available, the message will be pulled. This is much preferable to a push based system, where
-bottlenecks in processing could cause an increase in heap pressure in the API nodes themselves.
- Price - SQS is very reasonably priced. Comcast operates multiple message queues for different environments (dev, staging, prod, etc).
-The price to use SQS is in the single digit dollars per month. VinylDNS can be tuned to run exclusively in the free tier .
-
-
-Review the Setup AWS SQS Guide for more information.
-
-MySQL
-VinylDNS has also implemented a message queue using MySQL, which incorporates the features that we currently utilize through AWS SQS
-such as changing visibility timeout and re-queuing operations.
-
-Review the Setup MySQL Guide for more information.
-
-LDAP
-VinylDNS uses LDAP in order to authenticate users in the Portal . LDAP is not used in the API, instead the API uses
-its own user and group database for authentication.
-
-When a user first logs into VinylDNS, their user information (first name, last name, user name, email) will be pulled from
-LDAP, and stored in the UserRepository
. Credentials will also be generated for the user and stored encrypted in the UserRepository
.
-
-Review the Setup LDAP Guide for more information

-VinylDNS: Setup API Server Setup API Server
-The API Server is the main run-time for VinylDNS. To setup the API server, follow these steps:
-
-
- Pre-requisites
- Setup AWS DynamoDB
- Setup MySQL
- Setup AWS SQS
- Configure API Server
- Using the API Docker Image
-
-
-Using the API Docker Image
-The API server is provided via the VinylDNS API Image .
-The docker image allows you to mount your own config, as well as your own external dependency jars.
-
-The API server is stateless , allowing you to run multiple instances in multiple data centers for high-availability
-purposes.
-
-Note: If using VinylDNS Java Crypto and the pre-requisites defined here, no additional jars need to be loaded.
-
-Environment variables
-
- MYSQL_ADDRESS
- the IP address of the mysql server; defaults to vinyldns-mysql
assuming a docker compose setup
- MYSQL_PORT
- the port of the mysql server; defaults to 3306
-
-
-Volume Mounts
-The API exposes volumes that allow the user to customize the runtime. Those mounts include:
-
-
- /opt/docker/lib_extra
- place here additional jar files that need to be loaded into the classpath when the application starts up.
-This is used for “plugins” that are proprietary or not part of the standard build. All jar files here will be placed on the class path.
- /opt/docker/conf
- place an application.conf
file here with your own custom settings. Once you have your config created,
-place here.
-
-
-Ports
-The API only exposes port 9000 for HTTP access to all endpoints

-VinylDNS: Setup AWS DynamoDB Setup AWS DynamoDB
-AWS DynamoDB is currently the default database
-for most of the data that is stored in our instance of VinylDNS. However, all table implementations are available in MySQL
- (see Setup MySQL Guide for more information). The following tables are present in DynamoDB in our instance of VinylDNS:
-
-
- RecordSetChange - audit history of all changes made to records
- Group - group information, including name, email and description
- Membership - connects users to groups
- GroupChange - holds audit history for groups
- UserChange - holds audit history for all users (only used in the portal currently)
- ZoneChange - audit history for changes to zones (not record related)
-
-
-Note: the DynamoDB RecordSet repository is only partially implemented. For use you would need to provide implementations of those methods
-
-AWS DynamoDB connection information is configured one time, and the same connection is used across all tables. Therefore,
-you must ensure that all tables live inside the same AWS region accessible by the same credentials.
-
-Setting up DynamoDB
-If the tables do not yet exist, starting up the application will automatically create the tables for you. Starting
-up the application for the first time is often the best way to setup the tables, as they do require attributes and indexes to be setup.
-
-Provisioned Throughput
-is a mechanism that controls how many reads and writes can happen concurrently against your tables and indexes. You can
-configure Auto Scaling for your tables, so you do not have to worry about these settings.
-
-The most important thing to remember for Provisioned Throughput is that you pay more for writes than reads . To manage,
-costs, it is important to use Auto-Scaling, or turn down your provisioned throughput settings to be really low.
-
-If your installation does not have large zones (100,000 records), and takes relatively low throughput, you can turn
-the throughput very low and operate in the “almost” free-tier.
-
-Configuring DynamoDB
-Before you can configure DynamoDB, make note of the AWS account (access key and secret access key) as well as the
-DynamoDB endpoint (region) that you will be using. Follow the API Database Configuration
-to complete the setup for the API.
-
-You also need to configure DynamoDB for the portal Portal Database Configuration
-
-RecordSet Table
-
-Each row in the RecordSet table is a RRSet
, which means it comprises one or more “Records” inside of it.
-
-Usage
-This table (and recordSetChange) require the highest throughput. If you have large zones, the first time
-you load a zone, all records will be loaded into the recordSet
table. If the settings are too low, it can take a long time
-for the records to be loaded, and worst case scenario the operation will fail.

-VinylDNS: Setup LDAP Setup LDAP
-VinylDNS uses LDAP for authenticating users in the portal as well as the source of user information loaded into
-VinylDNS. VinylDNS does support service accounts, which are useful for automation.
-
-Important Note: VinylDNS presently maintains its own user, group, and membership repository. The only way for a
-user to be created is to login to the portal. Implementers can choose to out-of-band manage the VinylDNS repositories.
-
-There are no steps necessary for setup than having a Directory that can communicate via LDAP, and a user (account) that
-can read data from the Directory. Once you have that information, proceed to the Portal Configuration .
-
-Considerations
-You should communicate to your Directory over LDAP using TLS. To do so, the SSL certs should be installed
-on the portal servers, or provided via a java trust store (key store). The portal provides an option to specific
-a java key store when it starts up.
-
-Configuring LDAP
-Before you can configure LDAP, make note of the host, username, and password that you will be using.
-Follow the Portal Configuration to complete the setup.
-
-Syncing users against LDAP
-VinylDNS has implemented an optional feature to perform a recurring LDAP lookup against all non-test users in the database and perform
-a user lock for users that no longer exist in the directory. Automated user locking of deprecated accounts both streamlines
-the user management process and enforces an extra layer of security around VinylDNS.

-VinylDNS: Setup AWS SQS Setup AWS SQS
-SQS is used to provide high-availability and failover in the event that a node crashes mid-stream while processing a message.
-The backend processing for VinylDNS is built to be idempotent so changes can be fully re-applied. The SQS queue
-also provides a mechanism to throttle updates, in the event that an out-of-control client submits thousands or
-millions of concurrent requests, they will all be throttled through SQS.
-
-You must setup an SQS queue before you can start working with VinylDNS. An AWS SQS Getting Started Guide
-provides the information you need to setup your queue.
-
-Setting up AWS SQS
-As opposed to DynamoDB and MySQL where everything is created when the application starts up, the SQS queue needs to be setup by hand.
-This section goes through those settings that are required.
-
-The traffic with AWS SQS is rather low. Presently, Comcast operates multiple SQS queues across multiple environments (dev, staging, prod),
-and incur a cost of less than $10 USD per month. SQS allows up to 1MM requests per month in the free tier. It is possible
-to operate VinylDNS entirely in the “free” tier. You can “tune down” your usage by increasing your polling interval.
-
-The following SQS Queue Attributes are recommended (these are in AWS when you create an SQS Queue):
-
-
- Queue Type
- Standard
- Delivery Delay
- 0 seconds
- Default Visibility Timeout
- 1 minute (how long it takes a record change to complete, usually a second)
- Message Retention Period
- 4 days
- Maximum Message Size
- 256KB
- Receive Message Wait Time
- 0 seconds
- Maximum Receives
- 100 (how many times a message will be retried before failing. Note: if any messages retry more than 100 times, there is likely a problem requiring immediate attention)
- Dead Letter Queue
- use a dead letter queue for all queues
-
-
-Configuring SQS
-Before you can configure SQS, make note of the AWS account (access key and secret access key) as well as the
-SQS Queue Url that you will be using. Follow the SQS Configuration to complete the setup.

-VinylDNS: Batch Changes Batch Changes
-Batch Changes is an alternative to submitting individual RecordSet changes and provides the following:
-
-
- The ability to include records of multiple record types across multiple zones.
- Input names are entered as fully-qualified domain names (or IP addresses for PTR records), so users don’t have to think in record/zone context.
-
-
-Access
-
- Access permissions will follow existing rules (admin group or ACL access). Note that an update (delete and add of the same record name, zone and record type combination) requires Write or Delete access.
- NEW Records in shared zones. All users are permitted to create new records or update unowned records in shared zones.
-
-
-Supported record types
-
- Current supported record types for Batch Change are: A , AAAA , CNAME , PTR , TXT , and MX .
- Additionally, there are A+PTR and AAAA+PTR types that will be processed as separate A (or AAAA) and PTR changes in the VinylDNS backend. Deletes for A+PTR and AAAA+PTR require Input Name and Record Data.
- Supported record types for records in shared zones may vary.
-Contact your VinylDNS administrators to find the allowed record types.
-This does not apply to zone administrators or users with specific ACL access rules.
-
-
-Requirements

- DNS change requests must contain at least one change.
- The maximum number of single changes within a Batch change varies by instance of VinylDNS. Contact your VinylDNS administrators to find the Batch change limit for your instance.
- To update an existing record, you must delete the record first and add all expected records within the same request; a delete and add of the same record set within a Batch change request will be processed as an update.
- When creating a new record in a shared zone, or updating an existing unowned record, a record owner group is required. Once the owner group is assigned only users in that group, zone admins, and users with ACL permissions can modify the record.

-VinylDNS: DNS Changes DNS Changes
-DNS Changes is an alternative to submitting individual RecordSet changes and provides the following:
-
-
- The ability to include records of multiple record types across multiple zones.
- Input names are entered as fully-qualified domain names (or IP addresses for PTR records), so users don’t have to think in record/zone context.
-
-
-Note : DNS Change is portal-only terminology. The API equivalent is batch change .
-
-Access
-
- Access permissions will follow existing rules (admin group or ACL access). Note that an update (delete and add of the same record name or delete of single entry of multi-record DNS record set, zone and record type combination) requires Write or Delete access.
- NEW Records in shared zones. All users are permitted to create new records or update unowned records in shared zones.
-
-
-Supported record types
-
- Current supported record types for DNS change are: A , AAAA , CNAME , PTR , TXT , and MX .
- Additionally, there are A+PTR and AAAA+PTR types that will be processed as separate A (or AAAA) and PTR changes in the VinylDNS backend. Deletes for A+PTR and AAAA+PTR require Input Name and Record Data.
- Supported record types for records in shared zones may vary.
-Contact your VinylDNS administrators to find the allowed record types.
-This does not apply to zone administrators or users with specific ACL access rules.
-
-
-Requirements
-
- DNS change requests must contain at least one change.
- The maximum number of single changes within a DNS change varies by instance of VinylDNS. Contact your VinylDNS administrators to find the DNS change limit for your instance.
- To update an existing record, you must delete the record first and add all expected records within the same request; a delete and add of the same record set within a DNS change request will be processed as an update.

-Groups are the primary way users are granted access to zones. Users can create groups for two purposes in VinylDNS: to be the zone admin group for a zone or to be assigned more limited access via ACL rules .

-VinylDNS: Manage Access Manage Access to Zones and Records
-Full Access
-Members of a zone admin group have full access to all records and permissions in the zone. Each zone is limited to one admin group. Typically, this should be a limited set of
-users. If you wish to add other users to a group you can do so in the Groups section of the portal.
-
-Limited Access
-If you don’t want a user to have full access to a zone you can use ACL rules to give them more granular access. With ACL rules, the zone admins can grant individual users or groups read, write or delete access to all records in the zone, or a subset of record names and/or types.
-
- Go to the desired zone
- Select the Manage Zone tab
- Select the Create ACL rule button
- Fill in the form
- Submit the form

-
-NEW Shared Zones
-The shared zone feature is designed to allow more granular record ownership and management in a flexible way. Super users can mark zones as ‘shared’ which then allow any users to create new records or claim existing unowned records in zones. Zone administrators can assign records in a shared zone to specific groups by designating a group when creating the record set or when updating existing records in the portal. Users who are not zone administrators can create new records in shared zones, or claim and modify unowned records in shared zones, through the DNS Changes interface.

-VinylDNS: Manage Records Manage Records
-There are currently two ways to manage records in the VinylDNS portal. This covers managing individual records through their associated zone. To manage multiple records at once, possibly across zones, and records in shared zones you can use the DNS Changes area of the portal.
-
-Access
-Only zone administrators and users with ACL rules can manage records this way.
-
-Supported record types
-A, AAAA, CNAME, DS, MX, NAPTR, NS, PTR, SRV, SSHFP, and TXT
-
-
-
-To manage records in a zone go to the Zones section of the portal and select the View button that corresponds with the zone you want to manage. The Manage Records tab will be the active tab by default. Once you are in the Manage Records tab of the zone, you can create new records sets or update or delete existing record sets.
-
-
-
-The Records pane, below the Recent Record Changes pane, lists record sets. Record sets are records that have the same
-name but different record data. Not all record types support record sets.
-
-When you make any change, it will be immediately queued for processing. Typically processing happens in a second or two. You may need to select the Refresh button if you don’t see the change reflected in the portal.
-
-If for any reason the change failed, you can view the change in the Recent Record Changes pane
-at the top of the screen, or look at the Change History tab to see what went wrong.
-The Additional Info column will contain details of the change failure.
-
-
-
-
-Record sorting and filtering
-It is now possible to sort records in VinylDNS by record name ascending/descending order in addition to filtering the record types that will be displayed, providing more ease and control when navigating your DNS records.
-To change the sort order for record name, click on the Name header in the Records table to toggle between ascending and descending order.
-To filter record types, click on the Filter By Record Type link to reveal the record type options and adjust your selection.
-
-
-
-When searching for a record name using the search bar, exact matches are returned; however it is possible to use *
to fuzzy match on desired patterns (e.g. foo*
will match foo
and foobar
).
-
-Sync Zones
-If you make changes to the records in a zone outside of VinylDNS you must manually sync the zone so VinylDNS is aware of those records. Use the Sync Zone button in the Records pane.

-VinylDNS: Manual Review & Scheduling DNS Changes: Manual Review & Scheduling
-
-Configuration Note: DNS Change manual review and scheduling are configured features in VinylDNS. Check with your VinylDNS administrators to determine if they are enabled in your instance.**
-
-
-
-Manual Review
-
-If a DNS Change is submitted with only non-fatal errors you will be notified to either correct those errors or submit your DNS Change for manual review.
-If you submit the DNS Change for manual review a VinylDNS administrator will determine if your request can be approved or if it needs to be rejected.
-After the review your DNS Change will include the review details, including the review status, reviewer name, review time and review comment, if provided.
-
-
-
-
-
-Scheduling
-
-VinylDNS processes DNS Changes immediately, unless they have a Request Date and Time. The day and time must be in the future. The portal accepts and returns the Request Date and Time as your local time.
-A VinylDNS administrator will review the DNS Change after the requested time and either approve or reject it for processing.
-
-
-Filter by Open Requests
-
-If you have many DNS Changes you may find it helpful to filter your list of requests by those that are currently open.
-In the top right corner of the DNS Changes table is a checkbox labeled “View Open Requests Only”. If the checkbox is selected the DNS Changes list will be limited to only Pending Review and Scheduled DNS Changes.
-
-
-
-Cancelling DNS Changes
-
-Users can cancel any DNS Change they create if it has a review status of “Pending Review”. Either select the “Cancel” button in the main DNS Changes list or the “Cancel” button in the DNS Change Detail page. A modal will appear for the user to confirm the cancellation.
-
-
-
-
-
-Reviewing Pending DNS Changes
-
-VinylDNS administrators can use the portal to review DNS Changes.
-
-In the DNS Changes view there are two tabs, “My Requests” and “All Requests”. “My Requests” are only your own DNS Changes.
-“All Requests” are requests by everyone in the VinylDNS instance. Both tabs can be filtered by open requests.
-
-
-
-On the detail page for a DNS change that is pending review, administrators will see a review section beneath the list of single changes.
-The administrator can provide a comment, then choose Approve or Reject and finally confirm their choice.
-If the DNS Change is approved and there are no new errors or it’s rejected then the review is completed and the DNS Change status and review information is updated.
-If the DNS Change still has errors after the approval attempt, the page will display the new errors and the administrator needs to address those or reject the DNS change.
