Refactored language file.

[gravejester]

This is all my commits since forking the main repository. It includes the first commits where I tried to fix the bugs in the matching rules, but at some point I decided to do a complete refactoring of the whole file.

Notable changes:

• Supports the Stop Parsing operator
• Added some illegal scopes (bad variable names and space after backtick ++)
• Moved almost all matching rules into the repository
• Grouped matching rules logically
• Added comments where I felt it was needed
• Much better command highlighting, with highlighting of parameters
• Workaround for highlighting the reserved word 'default' in switch-blocks (Will only highlight the word inside scriptblocks, so will also highlight in {default}
• Fixed highlighting of comment based help keywords
• More consequent highlighting of numerical constants
• Changed some scope names
• Better type highlighting
• Highlighting of keywords in classes
• Added highlighting of built-in aliases and executable files (.ps1, .exe etc)
• Added highlighting of some missing operators
• Better highlighting of properties/members
• Added test-files for testing syntax highlighting (in \examples)

Awesome! So many great improvements here. I was just spot checking the before and after examples you linked to and noticed this:

Looks like the #\test.exe $roman part should be considered a comment but isn't in your latest changes. If it's easy to fix for this PR it'd be great to have it in. Otherwise we can just file a bug and fix it later.

This is excellent work, man. Once you feel like you're done making changes for now you should submit a pull request to the VS Code repo to replace this file:

https://github.com/Microsoft/vscode/blob/master/extensions/powershell/syntaxes/PowershellSyntax.tmLanguage

I want you to get the credit for these contributions by getting your PR accepted there :)

And when you submit your PR to VS Code, mention me in the PR message so that I can jump in and encourage them to accept the change.

heh.. that is actually just a typo in the comment, it should say 'shouldn't' :D

[daviwil]

Ahhh! That makes more sense :) Great, merging this now, thanks again!

[gravejester]

Cool, thanks! :)
