Support Bash

This has pretty much already been done for you, just need to pull in the files. I have been working with Petr Kovář to fix a couple of bugs.

Thank you for working on this!

I collected a few historical resources for reference, since there have been efforts to create a Bash scanner in the past:

• A very old open ticket on the CodeRay Redmine project for a Bash scanner
• Vincent Landgraf wrote a Bash scanner
• Anh Ky Huynh also wrote one
• And now, finally, Petr Kovář's and your Bash scanner, the only one compatible with CodeRay 1.0

I want to include it in the next minor release of CodeRay. To do that, we need example code - lots of it, since Bash is not a simple language. So, in addition to the test files included in the coderay_bash repository, I added all Bash scripts in rvm.

The bash-scanner branch includes your scanner, so I can test it. Unfortunately, the large rvm file breaks it:

Can you look into that?

[pejuko]

Im working on this. Unfotunately im without internet and time for next week.

[korny]

Great :-) Thank you.

[funglaub]

Any updates on this issue? Really would like to see Bash being added to CodeRay.

[pejuko]

seems latest coderay_bash (1.0.4) does not break with this file. there are, however, still highlighting bugs

[korny]

I updated the scanner to the last version from coderay_bash. Unfortunately, it's still broken.

A simple check:

> CodeRay.scan('"$("', :bash).debug

string<delimiter(")shell<delimiter($()delimiter(")

The problem is in the way it tries to handle nested strings – it doesn't. Instead of properly using a stack, it only has on/off flags for @quote and @shell.

In the current state, I can't accept this scanner.

Anybody wants to try and fix this one? A working implementation of nested strings can be found in the Ruby scanner (inline_block_stack).

In case of interest, the candidate scanners were removed with a1582d7. As a
workaround, I am now using Rouge, which has a shell/bash lexer already.
