(Windows10) FileNotFoundError

Here's what happens when I try to run gvim from the command-line:

X:\Desktop>vim-profiler.py gvim

FileNotFoundError: [WinError 2] The system cannot find the file specified

And regular vim isn't detected:

X:\Desktop>vim-profiler.py vim

No plugin found. Exiting.

I have 32-bit vim 8 from this repo, with Python 2.7.0 and Python 3.4.0 installed

This tool was made with Linux/OS X in mind, so making it work on Windows might require some modifications.

It seems that subprocess.call cannot find gvim: does running gvim in your shell alone works? As for vim, it seems that the script could not find your plugin directory. Could you provide more information on your setup (e.g. where are the plugins located)?

It's cool and somewhat expected, Windows always gets the short end of the foss-stick :P

Yeah, both it and regular vim are in my PATH environment variable

Could you provide more information on your setup (e.g. where are the plugins located)?

The vim folder in Windows is located at $HOME/vimfiles, and I used vim-plug, so they're under the plugged folder. However, it probably isn't related to plugin location because I was able to use the profiler just fine on Debian with my same vim setup.

Either way, thanks for the useful tool!

Figured out the gvim error! The Windows installer uses .bat files to launch the executable files, so by using the direct path, I don't get all the errors anymore:

X:\Desktop>vim-profiler.py "C:\Program Files (x86)\Vim\vim80\gvim.exe"
Running C:\Program Files (x86)\Vim\vim80\gvim.exe to generate startup logs... done.

However, it still can't find plugins

[bchretien]

If you're familiar with Python, you can take a look at the __guess_plugin_dir method. This is probably where something goes wrong (user plugin directory detection fails). Can you try to run the profiler with the -s option? It will take system plugins into account as well.

[bchretien]

We could probably add appveyor support as well, that would allow ensuring continuous support for Windows.

It is because all regex search are written as "sourcing (.+?)/(?:[^/]+/)(?:%s)/[^/]+" which should be r"sourcing (.+?)\\(?:[^\\]+\\)(?:%s)\\[^\\]+" for Windows. Delimiters are hard-coded as /. Also, self.system_dirs = ["/usr", "/usr/local"] makes no sense for Windows. I simply give it an empty list.

After fixing these problems, it runs successfully on Windows for both vim and gvim.

However, instead of using regex on full paths, pathlib.Path.parts or os.path.split should be more elegant and predicable. These built-in libraries are designed for cross-platform and complex environments (Network drives, UNC, symbol links, etc.).
