Yep, looking forward to it. I'm going to write an email with Sphinx transition
schedule once Sphinx 5.3 gets released (should happen during the upcoming weekend).
I have general comments about the Python scripts:
1) please follow the Python coding style and not the GCC one (I'm going to document
it in https://gcc.gnu.org/codingconventions.html under a new Python section).
The easiest approach is using flake8 and the following plugins:
python3-flake8, python3-flake8-builtins, python3-flake8-bugbear, python3-flake8-import-order, python3-flake8-quotes
plus, you might want to come up with a setup.cfg like we have in:
./maintainer-scripts/setup.cfg

Hi Martin,
many thanks for the pointers to the style tool and python lint - I'll
reformat the code accordingly.

yes sounds sensible. Thanks for the detailed
observations/suggestions/improvements below - I agree with them all and
will fix/change the code and then repost the patch

Gaius

Hi Martin,
here is the revised patch having applied all previous recommendations:
https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603436.html
Is this ok now? Thanks for the improvement suggestions (argparse
results in fewer lines of code :-)
regards,
Gaius

Hi.

Thanks, much better, however some comments are still not addressed:
1) I would prefer using ' instead of ":
$ flake8 ./gcc/m2/tools-src/tidydates.py
...
./gcc/m2/tools-src/tidydates.py:124:30: Q000 Double quotes found but single quotes preferred
./gcc/m2/tools-src/tidydates.py:127:27: Q000 Double quotes found but single quotes preferred
./gcc/m2/tools-src/tidydates.py:132:27: Q000 Double quotes found but single quotes preferred
./gcc/m2/tools-src/tidydates.py:133:33: Q000 Double quotes found but single quotes preferred
./gcc/m2/tools-src/tidydates.py:138:26: Q000 Double quotes found but single quotes preferred
./gcc/m2/tools-src/tidydates.py:143:28: Q000 Double quotes found but single quotes preferred
2) Python-names would be nicer:
def writeTemplate(fo, magic, start, end, dates, contribution, summary, lic):
def write_template(...)
3) def hasExt(name, ext) - please use Path from pathlib
4) while (str.find(line, "(*") != -1):
'(*' in line
? Similarly elsewhere.
5) str.find(line, ...)
Use rather directly: line.find(...)
6) please use flake8:
https://gcc.gnu.org/codingconventions.html#python
Thanks,
Martin
P.S. I'm going to merge Sphinx branch this Wednesday, so then we should port your
conversion scripts to emit .rst instead of .texi.

should be good - I'll complete the rst output in the scripts,

Hi.
As you probably noticed, the Sphinx migration didn't go well. However, it's still up to you
if you want to use it or not for Modula 2. We have manuals like libgccjit, or Ada manuals
that use RST natively and provide exported .texi files.
Cheers and sorry for the troubles I caused.
Martin

Hi Martin,

Yes, sorry to see this didn't happen. Thank you for your hard work and
I hope it can occur in the future.

Once modula-2 is in master I'd like to revisit rst in devel/modula-2
along with analyzer patches and m2 generics. If successful then submit
patches in early stage 1.

Ok thanks for the pointers, I will experiment with these build rhunes.
> Cheers and sorry for the troubles I caused.
No problem at all - the modula-2 scripts are now improved and cleaner
due to the port. Hopefully rst will happen sometime in the future,
regards,
Gaius

Hi.
We'll see, it's not in my plans for near future.

Likewise, thanks for all your work on this.

Am I right in thinking the analyzer stuff would be an updated version
of the work you posted here:
https://gcc.gnu.org/pipermail/gcc-patches/2021-April/567953.html
?
Thanks
