IPython Syntax Highlighting about ne HOT 5 CLOSED

@carlsmith could you post a gist of your .jsf? These things are incredibly hard to describe. To paraphrase: talking about .jsf is like dancing about architecture.

Here's me, eating my words. Remember what I said about talking about .jsf is like dancing about architecture? Time to dance. :) I sort of see what you're shooting for, but I'd like to suggest a less invasive approach. Let's go back to the python.jsf as distributed with ne and start fresh from there.

Notice that all states with the exception of :idle of course (and ":comment", which is probably a mistake) which transition to "idle" do so with a noeat. This is very important, as it means that pretty much every "\n" is going to send you back to "idle".

From my reading of the iPython pages, the only times we deviate from normal Python syntax is at the beginning of lines or immediately after an equals sign, give or take some white space. So let's wedge this in between the existing colour definitions and "idle":

=IpTag          inverse green
=IpString       inverse yellow

:maybe_ip Idle
        *               idle            noeat
        " \t"           maybe_ip
        "!%"            ip_tag          noeat
:ip_tag IpTag
        *               ip_string       noeat
        "!%"            ip_tag
:ip_string IpString
        *               ip_string
        "\n"            maybe_ip

This defines two new colors: one for the tags and one for the strings. It also makes your default/first state "maybe_ip" using the Idle colour. It skips over spaces looking for either "!" or "%" without consuming them. Anything else sends us to "idle", so we don't mess up the rest of the Python syntax. "ip_tag" eats the bang and percent signs, then transitions to "ip_string", which eats everything to the end of line.

We still need "idle" to deal with possible iPython magic after an equals sign or new lines. So let's add this transition to "idle":

  "=\n"           maybe_ip

It eats, so the equal sign gets the Idle colour, but we go looking for iPython magic. If we don't find it, "maybe_ip" noeats and goes right back to Idle, so again, we don't break any of the Python syntax.

The only other thing I'm seeing is the missing noeat on "comment"'s transition on newline, so add that:

  "\n"            idle            noeat

And I think we're done. You'll probably want to tweak the colors, and you may find some circumstances that I didn't spot. But I think we're closer to what you wanted without breaking the existing Python bits. Give it a try and let us know what you think.

No problem @utoddl. The gist is online here. I added a comment there that points out what edits have been made to the original file. Thank you for looking into this.

My approach was to just try and highlight the commands magenta, but ideally, they should be highlighted using sh.jsf.

If we can get IPython syntax highlighting working properly, I'll post something to the IPython mailing list, sharing my configuration, and explaining and plugging ne a bit. I'm sure there are more than few people there that would be interested.

Thank you for this @utoddl. It's really kind of you to take the time, and your help is much appreciated mate. I'll check the new code out this evening, and let you know how it goes. I really just wanted to say thank you.

I just got a chance to try it out. It works perfectly. Thank you @utoddl.

I'm a ne fan! IPython support is a really nice extra, and your willingness to help your users like you have here is really appreciated. I'm genuinely happy pluggingne, and will let the IPython community now about this feature and ne soon.

Awesome work. Thanks again man.
