The following change in Mbed OS added an environment marker to the python requirements file: https://github.com/ARMmbed/mbed-os/pull/10096/files#diff-b4ef698db8ca845e5845c4618278f29aR24 Mbed CLI did not know how to parse this, so a warning was always generated. This change now parses the "platform_system" marker, and adds a mechanism to add more if needed in the future.

There was a problem hiding this comment.
A python requirements file looks like this:
pyusb>=1.0.0,<2.0.0
hidapi>=0.7.99,<0.8.0;platform_system!="Linux"
line_parts for the first line would look like: ["pyusb>=1.0.0,<2.0.0"].
For the second one, it would look like ["hidapi>=0.7.99,<0.8.0", "platform_system!=\"Linux\""].
So the [1:] only selects what comes after the first ;, if there is one, which is the environment markers that we're trying to parse.

code caters for the cases I can know of, welcome improvement. |

Mbed CLI did not know how to parse this, so a warning was always
generated. This change now parses the "platform_system" marker, and
adds a mechanism to add more if needed in the future.
This fixes #888.
