Python interpreter on macOS 12.3

[schoeps]

Apple will finally drop python 2 in macOS 12.3. It's already missing in the current beta. Unfortunately, there is no binary /usr/bin/python but only /usr/bin/python3. Therefore this workflows fails although being python3 compatible (since #111). However, manually correcting the python path in the first line (hash-bang) works for me.

[nimacodes]

Could you advise in which file you are changing the python path? I have the the python environment variable TM_PYTHON in TextMate, but unfortunately this does not seem to work.

[schoeps]

I manually changed the hash-bang from #!/usr/bin/python to #!/usr/bin/python3 in the *.py-files in ~/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/...

(by the way: I hope the maintainers will fix this soon since 12.3 is out)

[nimacodes]

Thanks, I changed the hash-bang but now it seems my homebrew python installation go messed up :D At least it is now finding the interpreter.

I am now on Monterey 12.3 and /usr/bin/python has disappeared as expected. I have tried replacing /usr/bin/python with /usr/bin/python3 throughout the bundle -- and it doesn't work. I get errors like ModuleNotFoundError: No module named 'Foundation'.

However, using /usr/local/bin/python2 does work. On my machine, this is actually a link to a build in /Library/Frameworks/Python.framework/Versions/2.7/bin/; I am embarrassed to say I don't remember where this came from -- possibly python.org! But I suspect not all users will have it.

I followed @schoeps advise, changed all references from python to python3 and installed pyobjc package. Now TextMate works as a charm again.

But @nimacodes wrote:

Which is indeed the solution. In particular: /usr/bin/python3 -m pip install pyobjc

[schoeps]

Sorry. I forgot to mention that you need pyobjc. I had it already installed :)

[andreasloe]

Unfortunatively, this does not work for me. I installed pyobjc, updated textmate (and my MacOS as well) and get the following error messages if I run LaTeX (cmd-R) Traceback (most recent call last): File "/Users/andreasloeffler/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/bin/texmate.py", line 1014, in status = command_parser.parse_stream() File "/Users/andreasloeffler/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/lib/Python/parsing.py", line 771, in parse_stream return super(LaTexMkParser, self).parse_stream() File "/Users/andreasloeffler/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/lib/Python/parsing.py", line 188, in parse_stream function(matching, line) File "/Users/andreasloeffler/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/lib/Python/parsing.py", line 790, in start_latex fatal_error, number_errors, number_warnings = parser.parse_stream() File "/Users/andreasloeffler/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/lib/Python/parsing.py", line 611, in parse_stream return super(LaTexParser, self).parse_stream() File "/Users/andreasloeffler/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/lib/Python/parsing.py", line 195, in parse_stream line = self.get_rewrapped_line() File "/Users/andreasloeffler/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/lib/Python/parsing.py", line 140, in get_rewrapped_line line = to_utf8(self.input_stream.readline()) File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/codecs.py", line 322, in decode (result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 128: invalid continuation byte

[defjaf]

Weird. Do you have any weird characters in your document? Can you run latex on that file outside of TM?

[defjaf]

Perhaps it's worth forking this bundle into a version with the hardcoded python3? Is there any way to force installation of pyobjc or at least give a useful message to users? (How did it work with the old python2 installation? Was pyobjc installed by Apple?)

[andreasloe]

Weird. Do you have any weird characters in your document? Can you run latex on that file outside of TM? I can run the file outside (using textstudio). I just checked a simple "Hello World" example and this wen through. Only skim shows an error Found 0 errors, and 0 warnings in this run 165:183: syntax error: Die interne Tabelle ist übergelaufen. (-2707) (internal table overflow). So this has to do with encoding?

[andreasloe]

(How did it work with the old python2 installation? Was pyobjc installed by Apple?) It worked smooth, very smooth. pyobic was not installed, I just installed today.

[nilsreiter]

Thanks for posting this! I followed the above (adjust the shebang, install pyobc) and the compilation now works fine, but syntax highlighting not (fork here). The LaTeX.plist file looks fine, but within TextMate, the bundle editor displays the corresponding grammar as empty.

[dagnolo]

I followed the suggestions above (change python to python3 in the .py files) and now TextMate indeed compiles in latex. However, it complains when I try to change the latex preferences (I need to change the pdf viewer since TextMate does not support synctex). This is the error message:

Failure running “Preferences…”. Preferences…: /Users/xxx/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/bin/configure.py: /usr/bin/python3: bad interpreter: Operation not permitted

Any further help? Thanks

[vschiavoni]

Also hitting this problem, hopefully this gets fixed soon. Thanks !

[defjaf]

I haven't seen any of the issues since

1. Changing /usr/bin/python to /usr/bin/python3 everywhere in the bundle.
2. Running /usr/bin/python3 -m pip install pyobjc

I did briefly see the syntax highlighting issue, but it went away after restarting textmate.

Hint: make sure that you make the python -> python3 change everywhere. I changed it in:

1. Commands/Lines to List Environment.tmCommand
2. Support/bin/configure.py
3. Support/bin/texdoc.py
4. Support/bin/texmate.py
5. Support/bin/texparser.py
6. Support/lib/Python/itemize.py

Note that the first one isn't python source, but an xml file.

[dagnolo]

Thanks! (In fact I previously missed to modify files 1 and 6 of your list)

[nilsreiter]

Hmm, I've missed the tmCommand file, but fixing that didn't fix the syntax highlighting issue. I'm thankful for other ideas :)

[dagnolo]

I agree... It worked for me on an old Mac, but not on a newer one in my office...

[vschiavoni]

To do 1) from @defjaf suggestion, I had to:

plutil -convert xml1 "Commands/Lines to List Environment.tmCommand"
(..do the edit..)
plutil -convert binary1 Commands/Lines\ to\ List\ Environment.tmCommand

[sorbits]

You don’t need to convert it back to binary. This is only to keep the size of bundle deployments/updates down.

In any case, the steps mentioned above from @defjaf worked for me on a new macbook pro M1 with macOS 12.3.

[dagnolo]

My fault, sorry. It now works also for me.

[juandesant]

The pull request #191 above would resolve this issue for everyone, it would be great if it could be approved… any maintainers for this repository?

[JackSteele]

I just made a similar PR in javascript.tmbundle, but it's been years since any have been approved. Having just found this, I am less optimistic.

[sanssecours]

Commit https://github.com/textmate/latex.tmbundle/commit/54d6709ba450d341e0f3d01c930f900c115f8ba8 should hopefully improve the current situation a little bit. On macOS 12.3 or later you still need to install PyObjC, using Terminal (or a similar application):

/usr/bin/pip3 install pyobjc

before you can use commands that depend on Python though. I tested the changes on macOS 11.6.5 and 12.3.1. At least translating a very small document with “Typeset & View (PDF)“ seems to work correctly. At the time of writing the new code is not yet part of the official Bundle index. This should (probably) be the case in the next days.

[nilsreiter]

I finally solved my syntax highlighting problem, but without fully understanding it. It has nothing to do with Python, but I'll describe it here because of the context.

Situation: In the bundle editor, all language grammars are there, except "LaTeX": It shows an empty pane with two curly braces { }. The file LaTeX.plist is there and readable and plutil has no complaints about it.

Solution: What finally fixed it was to change the UUID of the grammar file (after converting it to xml). Suddenly, everything works as expected. I tried to find if some other bundle is using the same, but didn't find anything in all my installed bundles.

@andreasloe Did you solve this problem? I seem to experience the same issue...

[Bibi]

It seems the parsing issue is NOT related to python: see https://github.com/textmate/latex.tmbundle/issues/198#issue-1568227275

/usr/bin/pip3 install pyobjc

It is not always recommended to meddle with the python that already comes installed with the system. Therefore, would it be possible for the bundle to link with the python indicated in the environment variable?
