First about Python error. It occurs in module cuda_fmt_python_reindent, which is separate addon:
Formatter for Python: ReIndent

can you uninstall it yet as temp solution?
I will see why AStyle formatter dont work.

I have Win10 with Python 3.14.2.
Installed formatter for Python: ReIndent.
it works here ok on this file:

Code: Select all

if TEXT_OS == 'linux':
    import subprocess
    try:
        LSB_RELEASE = subprocess.check_output('cat /etc/lsb-release', shell=True).decode('utf-8')
        if ("Ubuntu" in LSB_RELEASE or "Debian" in LSB_RELEASE) and (TEXT_CPU == 'amd64'):
            DEBIAN_UBUNTU = True
    except:
        pass
maybe it crashes on specific Py script? can you give me minimal example?

Now about AStyle formatter. You have Python 3.14. Formatter is based on 'pyastyle' lib. I asked Qwen AI:

>Python PyAStyle library from https://pypi.org/project/pyastyle/#files - does it work under Python 3.14 on Linux x64?

Reply:
Short Answer: No, pyastyle does not work under Python 3.14 on Linux x64 — and it is very unlikely to work without significant modifications.

Why It Won't Work Out-of-the-Box:

- Abandoned Project: The GitHub repository (https://github.com/timonwong/pyastyle) has had no commits since December 2015
GitHub
. The project is effectively unmaintained.

- C Extension Compatibility Issues: pyastyle is a C extension module wrapping the Artistic Style C++ library. Python 3.14 introduced significant C API changes, including:
New configuration API (PEP 741)
www.c-sharpcorner.com
Free-threading/GIL-related changes (PEP 703)
Python
Extension modules must now be audited for multiple-interpreter compatibility
Python

- No Source Build Guarantee: Even if you attempt to build from the source distribution (pyastyle-1.1.5.zip), you would need:
A working C/C++ toolchain on Linux x64
Python 3.14 development headers
Likely manual patches to handle deprecated/removed C API functions
--------------

so sorry, AStyle formatter is not working for you and for me. Maybe I will remove it.
if you need some C++ formatter, I maybe will try to make one from 'clang' tool. No promise.

Thanks for the detailed response. AStyle - removed. Python: ReIndent tried on your example, works. At first I did not understand, the error writes when there are some places that cannot process.
On C++: I noticed that in the window of removing plugins there is a C++ lexer, (lexer: C++). For work it requires an Assembly lexer. All installed, but in cudaformater in the settings of C++ is missing.

>in cudaformater in the settings of C++ is missing.

You removed AStyle-fmt, so now you don't have C++ formatter, so C++ is missing. It's ok. Or I don't understand the issue.


>ReIndent... At first I did not understand, the error writes when there are some places that cannot process.

Can you give me example file? To fix the crash.

BTW, for Python it's recomended to use new formatter+linter:
`Linter for Python, using Ruff`.

Needs ruff. See its readme/readme.txt.

It is not for CudaFormatter, but it is also a formatter! it gives the menu item: 'Plugins / Ruff / Format current file'.
Seems it cannot format 'on saving', sorry.

I removed 'formatter Python ReIndent' because it is based on old script
https://pypi.org/project/reindent/
which has several forks, none of which is new. one fork which makes fix for multiline strings, was removed from github.

Modern alternatives
- formatter Python Black
- linter Python Ruff

I took your example.

Code: Select all

if TEXT_OS == 'linux':
    import subprocess
    try:
        LSB_RELEASE = subprocess.check_output('cat /etc/lsb-release', shell=True).decode('utf-8')
        if ("Ubuntu" in LSB_RELEASE or "Debian" in LSB_RELEASE) and (TEXT_CPU == 'amd64'):
            DEBIAN_UBUNTU = True
    except:
        pass
In line 5, I removed two spaces before the second "if". In this case, I get an error.

With installed "formatter Python ReIndent" (Python Black - not installed)

Now I reproduce it, tks. Yes, all formatters crash with wrong indent on line 5. Do we need to catch the exception and show nice msg-box to user? Or is the wrong syntax - must be handled by the linter (e.g. Ruff linter)? Will think.
