This is not so simple either. When I said that TW detects and quotes
arguments with spaces, I wasn't entirely correct. It looks like this
is done automatically by the underlying Qt framework, because I don't
see anything specific for that in the TW code. I don't know if this
can be controlled.
Then, there is a problem that cmd.exe does its own argument parsing,
which uses different quoting/escaping rules than those used in APIs
for process creation. And Qt seems to be geared towards APIs rules.
For example, if I specify in TW tools:
Arguments: "a b c"
it will be passed as:
"\"a b c\""
This would really confuse cmd.exe, so direct quoting in the tools
config doesn't seem to be an option, at least not if Qt is allowed to
I would have to spend some time to find a reasonable solution. If TW
team is interested in sorting this out, I can assist.
