I have succeeded to compile demo web application using OCaml and Ocsigen server but it's tricky to edit *.eliom, *.eliomi, *.ml and *.mli files because there is no syntax for OCaml. Erlang seems to be best option but it has some issues comparately to OCaml syntax. Can I add new syntax definition myself or I should ask developers about it?

I running a mediawiki and want to use syntax highlighting. I am using the extension https://www.mediawiki.org/wiki/Extension:SyntaxHighlight for that.
That works pretty fine.
Alas I want to highlight a language that is not part of this extension. So I wrote an python egg to extend pygments so it can parse my language (using entry points). This works fine.
Now I am struggling to get both to work together. How do I tell the GeShi Extension of MediaWiki to use my pygments extension? What do I have to do, so that using <syntaxhighlight lang="myLanguage"> will result in using my language lexer and style?
The solution was quite simple. One has to edit the file SyntaxHighlight_GeSHi.lexers.php and add the lexer.
It's important to use only lowercase for the lexer name, otherwise the extension will not find the lexer.
I have been using perltidy and Perl::Critic for checking Perl code before committing. Do we have any tool or module to the similar check for the TCL code?
The usual recommendation in this area is Nagelfar, which is more up to date than most of the other alternatives. There may be other commercial options as well.
tclcheck, which is included in tclsqueak seems decent, is under development and the author is responsive to error reports.
How do I define a custom syntax with highlighting in Monodevelop (v3.0.6) for log files or JSON files. I only could find Syntax_Mode_Definition but it only shows very short snippets which are hard to understand.
Could somebody just show/link a short examlpe how such a file should look like and where it should be put?
You can find most of the built-in syntax highlighting definitions here.
To add one, you would have to write an addin that registers the definition and registers the mimetype.
What syntax highlighting is used on GitHub (for HTML, CSS, JavaScript, C#) when viewing source code-file and is it available for the public to use?
It works on the page and it works when embedding on a page (from a Gist), like this:
<script src="https://gist.github.com/1009439.js"></script>
But can I just include their JavaScript-library and let it highlight my code?
Github uses pygments to highlight syntax. Pygments is running on the server, instead of a pure Javascript client solution. If you're looking for a Javascript solution check out this review of the various options.
According to this help page, GitHub currently highlights syntax with the open-source Linguist library for Ruby. Linguist highlights each language using the tmLanguage files linked in vendor/grammars.
Since Linguist is written in Ruby, it can only be used on the server. If you want a client-side JavaScript library that you can just include on a page, you will have to find a different library.
According to this: http://www.infoq.com/news/2008/03/github-git-repository-hosting
they are using Python Pygments
Chris Wanstrath shared some
information about the inner workings
of GitHub with InfoQ:
GitHub is mostly implemented in Rails.
The post-commit integration mini-apps
we're working on are all written in
Merb, we use the Python Pygments for
syntax highlighting, and we use Ara T.
Howard's Bj plus some Ruby scripts for
our queueing system. And, of course,
we use the Ruby Grit library to
interface with Git.
I believe they use their albino gem. It is a Ruby wrapper for the pygments syntax highlighter.
Here is an article of a comparison I read recently on javascript based syntax highlighters (if that is what you need): http://softwaremaniacs.org/blog/2011/05/22/highlighters-comparison/
As others have said previously, GitHub uses Pygments. You can achieve the same effect by using it together with pygments-style-github.
Is there a place I can find Backus–Naur Form or BNF grammars for popular languages? Whenever I do a search I don't turn up much, but I figure they must be published somewhere. I'm most interested in seeing one for Objective-C and maybe MySQL.
you have to search on tools used to create grammars: "lex/yacc grammar", "antlr grammar" "railroad diagram"
http://www.antlr3.org/grammar/list.html
Here's some grammar files

ruby

FWIW, the MySQL grammar file (mysql-server/sql/sql_yacc.y) is open source and browseable at launchpad.net (though it's a bit slow and I got an error when I tried to pull up the specific file).
Also, a snapshot of the whole MySQL Server source is downloadable from dev.mysql.com.
There are some links from w:BNF#Language Grammars.
BNF Grammars for SQL-92, SQL-99 and SQL-2003
I also found a page that lists grammars for Objective C.
Objective-C grammar for Lex/Yacc Flex/Bison
Reference Manual for the Objective-C Language
IIRC, BNF grammars are just different enough from what yacc/bison want as input to be really annoying :) If you intend to feed these files into a parser generator, you may want to look for files in the appropriate format. I recall seeing such files for Java, JavaScript and C++ at one point. Probably as part of Eclipse, Firefox and GCC, respectively, but I can't remember for sure. I would assume you can find pretty much any parser input file by finding an open source project that uses that language.
I also searched this and i collected this repository
