plugin CudaFormatter + its formatters

[dima8101]

when plugin error occurs, usually it is a plugin crash, so see the Console panel for crash (red) lines there ...

An error occurs when auto-formatting a python file. The file is not auto-formatted.
When auto-formatting a C++ file, no errors occur at all. The file is not auto-formatted. However, the status bar displays [AStyle (C++)] Cannot format text.

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.

[main Alexey]

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?

[main Alexey]

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.

[dima8101]

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.

[main Alexey]

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.

[main Alexey]

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.

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.
