Description

Feature request

Feature description

A recent bugfix (https://github.com/ros2/launch_ros/pull/83) raised awareness about how we handle paths in launch. If launch actions and substitutions do not support POSIX paths but only native ones, platform-specific variations (e.g. slashes vs backslashes) creep all the way up to the launch file. At its worst, it makes XML -- and any other markup-based launch file -- platform-specific.

We should support POSIX paths across launch and encourage downstream packages' authors to maintain that support.

Research direction

Start by surveying path handling across launch actions and substitutions, including the XML launch-file path representation described in the issue. Done means POSIX paths work across launch and downstream packages without platform-specific slash or backslash requirements.
