For the tmLanguage gurus, a question

[handycam]

I'm trying to make a change to the SCSS language file to correctly color a nested include in a Susy scss file

As in

Code: Select all

@include at-breakpoint(900 12) {
    @include susy-grid-background;

The current code only "closes" the previous scope when it hits a ; apparently. How can I edit the below code to also end at a {

Code: Select all

<key>end</key>
<string>\s*((;)|(?=\}))</string>


[handycam]

I think I've got it:

Code: Select all

<string>\s*((;)|(?=\})|(\{))</string>

Correct? Seems to work.

If I make edits like these, do I just edit the tmLanguage file in place, or make a copy in my user folder, or what's the safe procedure?

[handycam]

The only thing that's still not 100% correct is that the semicolon and the bracket at the end of the line is included in the scope, and is gold in my theme, when other ; and { are white...

I think you only need this:

Code: Select all

<key>end</key>
<string>(?=[;{])</string>

Indeed, thanks. Can you please translate?

(?=...) is a look ahead expression, meaning that it matches if ... matches next, but doesn't make ... part of the match. See http://www.regular-expressions.info/lookaround.html

Thank you. I've never used look-aheads before, I will start now!

Be aware that some features are missing from the regex parser for syntax definitions. Here is the documentation. Notably absent are conditionals.

Re-opening this old thread with a very very similar question.

I'm using the below regex to match just the (\w+), not the whole line. I'm doing this with a (?:...) as described in the documentation as a "not captured group" but I've also tried the previously mentioned (?=...) as well with similar failures.

Code: Select all

      <dict>
         <key>match</key>
         <string>(?:object network) (\w+)</string>
         <key>name</key>
         <string>keyword.network.object.cisco</string>
      </dict>


The above code matches the entire line below:

Code: Select all

object network myInsideNetwork

How can I apply the keyword.network.object.cisco style to just the (\w+) and not the whole line?
