Re: creating a new importer for parse-body use
Thanks Edward. It looks like addressing the first of these:
> You have to make @language tds work by creating entries for tds in three
dictionaries in leoApp.py.
Is what I need to look at first.

Yes, it should be enough, provided that '@language tds' is supported.
I intend to select this parser by means of '@language tds', but with just

Creating modes/tds.py only affects colorizing. It should have no effect on
importers.
Any thoughts? In any case, that error message might be improved IMO

Hehe. I agree the message leaves a bit to be desired.
However, the traceback is actually pretty informative. As usual, the last
two lines are the most informative. Clearly, g.app.language_extension_dict.get(
language) is returning None.
The "language" var comes from the line:
language = g.scanForAtLanguage(c, p), so yes, you must support your new
language by creating entries in three language dictionaries. See the node
"app.__init__ (helpers contain language dicts)" in leoApp.py.
*Summary*
You have to make @language tds work by creating entries for tds in three
dictionaries in leoApp.py.
You have to create an importer for .tds files.
parse_body shouldn't crash if g.app.language_extension_dict.get( language)
is None.

creating a new importer for parse-body use
Hi (Edward, probably)
I am interested in writing an importer to allow me to use the parse-body
command on a simple format I use for making notes (it's similar to the
format used by the old Origami editor used for Transputer occam files in
the TDS; Transputer development system)
I'm starting with a stripped-down file
leo/plugins/importers/tds.py
based on others in that directory.
I'm a little unclear as to whether just that file will be enough; I intend
to select this parser by means of '@language tds', but with just 'noddy'
contents of the tds importer I am seeing an error like:
{{{
Traceback (most recent call last):
File "/home/jkn/leo-editor/leo/core/leoKeys.py", line 2466, in
callAltXFunction
func(event)
File "/home/jkn/leo-editor/leo/core/leoImport.py", line 2738, in
parse_body_command
c.importCommands.parse_body(c.p)
File "/home/jkn/leo-editor/leo/core/leoImport.py", line 1137, in parse_body
ext = '.' + g.app.language_extension_dict.get(language)
TypeError: can only concatenate str (not "NoneType") to str
}}}
I have tried creating a matching file colorizor leo/modes/tds.py, without
success
Any thoughts? In any case, that error message might be improved IMO
