Changing stuff in Geany

I use Geany for my IDE. It’s pretty good for what I do. I’m no hardcore coder. I just use Python for experimenting and learning.

It had been a little while since I did anything with Python. In fact, the last time I used it was before I installed Arch. I got a little bit of coding fever and wanted to refresh my memory. I was thinking about rewriting my Sudoku solver program, using functions instead of the hot mess that I left it in a few months ago.

But I was running into a little problem. When I would press F5 to run my program, the terminal that popped up gave me this error message:

./geany_run_script.sh: line 5: python: command not found

------------------
(program exited with code: 127)
Press return to continue

“Well that’s no good,” I thought. It turns out that Geany was trying to run Python with the command “python,” which would be fine if “python” were the command it needed to run. But since I am using Arch, “python” is for the bleeding edge Python 3, whereas the more commonly used Python 2.7 is called with “python2.” Since I didn’t want to use Python 3 and didn’t have it installed, I needed to change the command to “python2″ so Geany wouldn’t give me these error messages anymore. Sure, I could just save the program and then open a terminal and type “python2 filename.py,” but that wouldn’t be a good solution because it would be a hassle.

I checked every preference menu I could find in Geany, but I couldn’t find a setting to change what it pointed to for running Python (or any other) programs. Then I looked all over the place for geany_run_script.sh, but I couldn’t find it anywhere, either. I did, however find some configuration files in /usr/share/geany. Particularly, I found /usr/share/geany/filetypes.python. That directory also had filetypes for all the languages that Geany supports. At the very end of filetypes.python were these lines:

[build_settings]
# %f will be replaced by the complete filename
# %e will be replaced by the filename without extension
# (use only one of it at one time)
compiler=python -m py_compile "%f"
run_cmd=python "%f"

Changing that last line took care of the problem:

run_cmd=python2 "%f"

So Geany stopped giving me error messages when I tried to run my Python programs and I was happy.

I still have a long way to go on rewriting my Sudoku solver, but I will post it here when it is updated. Keep an eye out.
