Feel free to come find me on Libera IRC, or suggest a preferred chat
option for you.

The stuff I want is actually quite simple, though:

(1) I want to confirm that camxes-py is the preferred Python option
these days

(2) I want to be able to run "run" (see
https://github.com/teleological/camxes-py/blob/master/camxes.py#L89
) or something like it in a direct, straightforward way, i.e.:

          import camxespy
          tree =3D camxespy.run("mi klama", transformer=3D'camxes-morpholog=
y')

, and tree should contain an obvious python representation of the
parse tree.

This requires, AFAICT (I don't actually know Python very well) that
camxes-py have a library struture to it that it doesn't currently
have and that the options be configurable in some way other than
OptionParser.

I can actually do all that myself, but I'm not really a pythonista
and what I do won't be idiomatic at all.

Stretch goals:

(3) Update to most-recent parsimonious; it currently breaks on
0.8.1, but works on 0.6.2

(4) Update to Python 3, but I'm perfectly capable of making a PR for
this myself.

(5) Make a mode that collapses productions with only one child, i.e.
make the output look like this (in terms of productions not syntax):

        rlpowell@stodi> echo "mi klama" | camxes -f
        Flat layout requested.
         text=3D(  sentence=3D(  CMAVO=3D(  KOhA=3D( mi )  )  BRIVLA=3D(  g=
ismu=3D( klama )  )  )  )

Instead of this:

root@66324b4aed4b:/src# python camxes.py "mi klama"
["text",["text_1",["paragraphs",["paragraph",["statement",["statement_1",["=
statement_2",["statement_3",["sentence",[["terms",["terms_1",["terms_2",["a=
bs_term",["abs_term_1",["sumti",["sumti_1",["sumti_2",["sumti_3",["sumti_4"=
,["sumti_5",["sumti_6",["KOhA_clause",[["KOhA","mi"]]]]]]]]]]]]]]],["CU"]],=
["bridi_tail",["bridi_tail_1",["bridi_tail_2",["bridi_tail_3",["selbri",["s=
elbri_1",["selbri_2",["selbri_3",["selbri_4",["selbri_5",["selbri_6",["tanr=
u_unit",["tanru_unit_1",["tanru_unit_2",["BRIVLA_clause",[["BRIVLA",["gismu=
","klama"]]]]]]]]]]]]]],["tail_terms",["VAU"]]]]]]]]]]]]]]]

, but as I said before this is not hard to do after the fact once
you have the parse tree.
