Ruby syntax highlighting

[szh]

Fabian Jakobs, can you please look at my ruby syntax highlighting draft? I can't get it to work, so I think I must be doing something wrong. Here's the draft:

github.com/Heigh-Tech/ace/blob/master/lib/ace/mode/ruby.js and https://github.com/Heigh-Tech/ace/blob/master/lib/ace/mode/ruby_highlight_rules.js

You can also see https://github.com/Heigh-Tech/cloud9 to look at what I've been doing to integrate it with the IDE.

Thanks!

Hi Shlomo,

Some thoughts from looking at the code.

- You can remove "DocCommentHighlightRules". I'm pretty sure they
don't apply for ruby
- the buildin variables look suspicious since they start with a "$"
(e.g. "$DEBUG") the "$" is a special character in regexps and needs to
be escaped. e.g. "\\$DEBUG"
- multi line strings work completely different in Ruby compared to
JavaScript. I'd remove them for the beginning
- I don't think ruby has future reserved keywords. You can remove this as well

Especially the second point will prevent your highlighter from working.

Best,
Fabian

Thanks for the suggestions. I tried that, and it still isn't working. Is there anything I'm doing wrong now?

It may have something to do with the ruby.js part. I didn't totally understand what to do there, so I basically copied most of it from JavaScript and Python.

The ruby.js looks ok. What exactly doesn't work and how do you test
it? To simplify the code you can remove the qstring and qqstring
states. Both are not used in Ruby. Also these two lines at the bottom
can go:

this.addRules(docComment.getRules(), "doc-");
this.$rules["doc-start"][0].next = "start";

Best,
Fabian

I found this error in Chrome's console which may be a possible hint:

Error:

Failed to load resource: the server responded with a status of 404 (Not Found)

Filename:

:3000/static/support/ace/lib/ace/worker/worker_client.js

I am not really sure what that means.

"What exactly doesn't work..."

 The text just doesn't get highlighted. It all stays black.

[Fabian Jakobs]

You can ignore this.

Can you check in your test code to github then I can take a look at
it. I don't see any references to ruby in the demo file
<https://github.com/Heigh-Tech/ace/blob/master/demo/startup.js>.

[szh]

Hmm. I didn't realize I had to edit that file :)

I'll do that now and try again.

I just finished adding ruby to demo/startup.js. What does that file do?

[Fabian Jakobs]

It is the implementation for the demo app (editor.html). I asume you
use this to test your code.

For future reference, this problem has now been fixed. It was because of some bugs in ruby_highlight_rules.js.
