Mercurial / GIT / Python3

[cederom]

Hello world, I have just cloned my project to a new macOS 10.14.4 machine, I am using MacPorts for Open-Source, and Python 3.7 VirtualEnv. Trying to work with mbedOS 5.12.2:

• mbed deploy seems to depend on hg command.
• hg command seems to be Mercurial binary.
• Mercurial does not seem to work with Python 3 yet.
• I cannot perform mbed deploy.

The question is why do I need Mercurial if all stuff is Git(Hub) based?

I had to install external Mercurial port in order to perform mbed deploy. It would be nice if mbed checked for all necessary dependencies (i.e. Mercurial).

Just an idea, but Mercurial could be part of pip install -U -r mbed-os/requirements.txt when Python3 compatibility is in production (Beta/RC already) so it could be also contained into a Python VirtualEnv directly..? :-)

This is rather a question to mbed-cli repo, but we can keep it here to have an answer.

Not all stuff is git based - repositories on our portal are mercurial based. When you used deploy - what repositories did it fetch ?

Hello @0xc0170 here is the output:

Just a bit confused why use hg to fetch git? Maybe that hg could be added into Python VirtualEnv..?
