Please send the UDL sources, not just the XPI.

Thanks,

komodo crash - sending file

purpledog — Thu, 26 Jun 2008 02:02:44 -0700

Where shall I send the file to?

Btw, there's no source code, just the directories/files created by koext and the xpi.

Could you send your source code to me?

New UDL-based languages should never cause Komodo to crash.
If you've run into a bug, I'd like to fix it as soon as possible.

Thanks,
Eric

komodo crash

purpledog — Wed, 25 Jun 2008 04:16:13 -0700

I followed those 3 step and installed the xpi (leaving the udl and ko*.py as is). Then I restarted Komodo and try switching to the new language but that simply crashed Komodo (Edit 4.4)...

Note that after the install I don't see any if the new language file in the komodo path (but I do see the glsl in the language menu)

That would be nice to have a "one click" command to create a new language (with empty highlights and so on)...

broken in 4.2.0 and 4.2.1

Please look at bug 72556 for some issues that break usage of 'koext' for relatively complex new UDL-based languages.

Introduction to building a Komodo extension

trentm — Thu, 06 Sep 2007 15:16:51 -0700

(A short while ago Jaroslaw Zabiello asked a question on the
komodo-discuss list that motivated me to finally write up a beginner intro
to using some new tools in Komodo 4.2 beta 7 for creating Komodo
extensions. Here is my slightly edited response.)

Jaroslaw Zabiello wrote:

is there any chance for syntax colouring for Mako templates
(http://makotemplates.org)...

This is certainly possible with Komodo's UDL (User-Defined Languages)
system.

You could take a stab at writing a Mako extension for Komodo (in
particular the Mako UDL definition) yourself. Komodo is still in the early
stages of making this kind of thing easy, but 4.2 (including the recent
beta7) improves on this a bit. Eric wrote up a (long) intro to writing UDL
definitions a while back on his blog:
http://blogs.activestate.com/ericp/2007/01/kid_adding_a_ne.html

Here is how packing up the Mako UDL into a Komodo extension would
basically work -- if you are willing to help us work out the kinks.
Komodo 4.2 beta 7 includes a sort of SDK in its install tree. On Linux and
Windows this is found at "installdir/lib/sdk". That SDK includes two
tools:

koext       a command line tool for working with Komodo extensions
luddite     a tools for working with UDL

Put the SDK bin dir on your PATH and you should be able to run koext and
luddite at the command line. Similar to tools like cvs or svn, these are
tools with multiple sub-commands. (If running these doesn't work for you,
then please let us know so we can make the environment setup more smooth.
There is currently a dependency on having a Python 2.5 installation --
which we should be able to remedy if necessary.)

Start your extension source dir (with `koext startext'):

$ koext help startext
...prints instructions on using this command...
$ koext startext mako_language
...follow instructions for other extension meta-data...

You should now be able to build your extension:
```
$ cd mako_language     # cd in to source dir
$ koext build
```
This will build an .xpi file that you can install into your Komodo.
However, the extension doesn't yet do anything.

Generate stubs for defining a new language for
Komodo:

$ cd mako_language
$ koext help startlang
...
$ koext startlang Mako --ext .mako --is-html-based

This will generate a few files that you'll then need to fill out with
appropriate information for Mako template files. Namely:

udl/mako-mainlex.udl
    The lexing/syntax-coloring UDL definition for Mako.
components/koMako_UDL_Language.py
    The PyXPCOM component that defines the language for
    Komodo.

Properly filling these out is a big topic beyond the scope of this email.
Your best references are:

Eric's blog post for UDL information.
The UDL reference in the Komodo documentation.
Example .udl files in the SDK directory (lib/sdk/udl/...)
Look at other ko*_UDL_Language.py files in your Komodo installation.
Many of the new languages added to Komodo in the 4.x series are based on
UDL and work in the exact same way as would your Mako language
component. Look for RHTML, Smarty, HTML, TemplateToolkit, and Mason.
They should be quite similar.

Note: Komodo also has a "Komodo Extension" project template that you could
use for starting out. However, we are still working on merging the project
template and the "koext" tool in the SDK (probably for Komodo 4.3).
