Ehm, thus 'shellxquote' should be "(, and we should turn that into )"
for the tail? It's possible, but I wonder where it breaks now.
Yes, I wonder:
* What is a problem
* Why 7.3.443 is needed.
Summary what I remember so far, and a suggestion at the end.
Please correct mistakes.
------------------------------------------
Bug (before the patch):
shellcmdflag: /c
shellxquote: empty
user executes :!"my editor.exe" "my file.txt"
vim executes cmd /c "my editor.exe" "my file.txt"
cmd executes my editor.exe" "my file.txt
(obviously wrong)
Problem: cmd sometimes strips outer quotes (and doesn't provide an
option to force keeping the quotes)
Solution: always add surrounding quotes and force removing them with /s
Patch:
shellcmdflag: /s /c
shellxquote: "
Yeah, this works now:
user executes :!"my editor.exe" "my file.txt"
vim executes cmd /s /c ""my editor.exe" "my file.txt""
cmd executes "my editor.exe" "my file.txt"
------------------------------------------
Bug (with the patch)
shellcmdflag: /s /c
shellxquote: "
user executes :!editor "my&file.txt"
vim executes cmd /s /c "editor "my&file.txt""
cmd executes "editor "my & file.txt""
(two commands, separated by `&')
Problem: cmd doesn't always strip *outer* quotes, but stops before `&'
Solution: make cmd's argument "atomic" by enclosing it in `('...`)'
Patch (by RoDo):
shellcmdflag: /c (no need to strip quotes)
shellxquote: ( (and automatically use `)' at the end)
Yeah, this works now (also did without patch 7.4.443):
user executes :!editor "my&file.txt"
vim executes cmd /c (editor "my&file.txt")
cmd executes (editor "my&file.txt")
------------------------------------------
Bug (with RoDo's patch)
shellcmdflag: /c
shellxquote: (
user executes :!echo a & echo b
vim executes cmd /c (echo a & echo b)
cmd executes (echo a & echo b)
-> output: two lines, `a' and `b)'
Problem: echo does not ignore the trailing `)'
Solution: enclose cmd's argument in `"('...`)"'
(I have no idea why this works)
Patch:
shellcmdflag: /c (not sure if `/s /c' would make a difference,
I'd expect `/c' to always remove outer quotes)
shellxquote: "(
or maybe:
shellxquote: "(,)" (new syntax!)
Yeah, this works now (also did without patch 7.3.443):
user executes :!echo a & echo b
