I'm trying to use astyle as my code formatter in Vim. However, I can't seem to find how to tell vim which options to use for astyle.
The following is in my vimrc:
autocmd BufNewFile,BufRead *.cpp set formatprg=astyle\
If given no options in command line mode, astyle will try to find an options file named .astyle. However this does not seem to work here. (Ie: when I format in vim: gqG
the result is totaly different than if I had called astyle from the command line !)
This is my .astyle options file:
--style=allman
--mode=c
--attach-classes # -xc
--attach-closing-while # -xV
--indent-classes # -C
--keep-one-line-blocks # -O
--keep-one-line-statements # -o
--align-pointer=name # -k3
So I tried to simply specify the options in my vimrc like in this answer:
autocmd BufNewFile,BufRead *.cpp set formatprg=astyle\ --style=allman --mode=c -xc -xV -C -O -o -k3
Saved, sourced, reloaded vim entierly: no change. The options seem to not take effect. When I format with gggqG
the result is still not what my options ask for... Can anyone see why this is not working ?
(Note: I want to be able to format using gq
and I don't mind reformatting the whole file entierly each time, unlike in this question)
EDIT: After a few stupid mistakes I've escaped all the spaces as suggested in @romainl comment. However there seems to be an error comming from vim which I cannot interpret:
/bin/bash: -c: line 1: syntax error: unexpected end of file
shell returned 1
E485: Can't read file /tmp/vHXZmnp/3
Since no one is answering, I'll share what I managed to come up with. Following the advice given in the comments I escaped all the spaces in the sequence of options passed to astyle. However, this leads to bash trying to interpret the options, failing and kindly telling us so: see question edit.
The solution that seems to work is to create a system wide astyle options file and pass the path to that using command line arguments instead of giving it the options directly. (This can probably also be done with a project options file but requires having an options file at the root directory of every project)
Taking my options file .astylerc
in my home directory this gives:
autocmd BufNewFile,BufRead *.cpp set formatprg=astyle\ --options="/home/myusername/.astylerc"\
Note that a relative path did not work, but it is possible to write the path to the options file using a 'pseudo relative' path using the $HOME
environment variable as mentioned in the astyle documentation
