basic test for spaces and args

[wchristian]

This serves as a demonstration for the problems in #143.

As far as i understand IPC::Run and comments as #143 (comment) , all of the calls below should work on windows, right?

Because right now (as well as with older versions) it looks like only these succeed:

ipctest.bat
.\ipctest.bat
dirnospace\ipctest.bat
D:\cpan\IPC-Run\eg\ipctest.bat
D:\cpan\IPC-Run\eg\dirnospace\ipctest.bat
D:/cpan/IPC-Run/eg/ipctest.bat
D:/cpan/IPC-Run/eg/dirnospace/ipctest.bat

Notable failures:

• spaces in dirs
• spaces in executable
• forward slashes in relative paths

Interestingly i was unable to reproduce the failure indicated by @stphnlyd in #143 (comment)

Note that i didn't yet consider the actual output of what's being run deeply, this mostly focuses on actually running it and getting basic arg behavior right. TODO: .exe files, .exe files with non-standard arg parsing, maybe more complicated args?

Comment invitation for @nmisch, @haarg, @toddr. (I think mohawk gets pinged automatically.)

run [ $_, "meep marp" ], ">", $out;

for all of

ipctest.bat
ipctest2 space.bat
.\ipctest.bat
./ipctest.bat
.\ipctest2 space.bat
./ipctest2 space.bat

Can you rebase this please?

I like the concept! I do think it would be better to capture all the tested files into a module and generate them in a tempdir, in a similar style to EUMM's https://github.com/Perl-Toolchain-Gang/ExtUtils-MakeMaker/blob/master/t/lib/MakeMaker/Test/Setup/XS.pm
