I'm using a wrapper script to comfortably start VS Code from file manager.
The last line of it is
cygstart --hide -- "/proc/cygdrive/c/Program Files/Microsoft VS Code/bin/code.cmd" "$(cygpath
-alw "$_arg")"
It works well up to the point where there are no spaces in the $_arg. But on
the first seen space it break the arguments list into pieces.
I have to double-quote the argument to maintain the consistency, like
cygstart --hide -- "/proc/cygdrive/c/Program Files/Microsoft VS Code/bin/code.cmd" "\"$(cygpath
-alw "$_arg")\""
but that's a questionable solution at best.
This is as expected. Unlike Cygwin's exec() emulation, cygstart does not
add any quoting during conversion of the argv[] array to the plain
argument string required for Windows process creation API.
Example:
$ cat test.cmd
@echo off
echo %%1 = '%1'>test.txt
echo %%2 = '%2'>>test.txt
echo %%3 = '%3'>>test.txt
echo %%4 = '%4'>>test.txt
echo %%5 = '%5'>>test.txt
$ ./test.cmd ArgOne 'Arg Two' 'Arg Three'; cat test.txt
%1 = 'ArgOne'
%2 = '"Arg Two"'
%3 = '"Arg Three"'
%4 = ''
%5 = ''
$ cygstart ./test.cmd ArgOne 'Arg Two' 'Arg Three';\
sleep 1; cat test.txt
%1 = 'ArgOne'
%2 = 'arg'
%3 = 'Two'
%4 = 'Arg'
%5 = 'Three'
$ cygstart ./test.cmd ArgOne '"Arg Two"' '"Arg Three"' ;\
sleep 1; cat test.txt
%1 = 'ArgOne'
%2 = '"Arg Two"'
%3 = '"Arg Three"'
%4 = ''
%5 = ''
$ cygstart ./test.cmd 'ArgOne "Arg Two" "Arg Three"' ;\
sleep 1; cat test.txt
%1 = 'ArgOne'
%2 = '"Arg Two"'
%3 = '"Arg Three"'
%4 = ''
%5 = ''
