Feature #16741: Implement Shellwords.shellescape correctly for Windows

• Status: Open

[abobrikovich (Alexander Bobrikovich)]

shellwords module was originally designed and developed for *NIX, and currently works like this:

require 'shellwords'

Shellwords.shellescape("/home/me/test with space.txt")
# => "/home/me/test\\ with\\ space.txt"

Shellwords.shellescape("C:\Program Files")
# => "C:Program\\ Files"

I think it's a good opportunity to extend it to support Windows. According to [2], it looks like using quotations is the only option for paths used in a batch script that have space inside. I propose:

Shellwords.shellescape("C:\Program Files")
# => "\"C:\Program Files\""

I think adding Shellwords.cmdescape is better than changing Shellwords.shellescape.

Some environments on Windows support both bash and cmd.

I agree with @znz (Kazuhiro NISHIYAMA). IMO, a gem named cmdwords or something would be a good start for the feature instead of directly extending shellwords.

I'm curious for what purpose you need to escape paths.
To pass it to another program, it is better to spawn or system with split array.
