implement a cargo clean feature

[allan-simon]

I'm conscious this is very trivial and it would take actually more character than writing rm -rf target however I see several advantages to this

• for non unix-user or "non-plateform user on which we're running the build/clean" it will not require the overhead of needing to search how to delete a directory on that plateform
• ease cross-plateform scripting
• easier to call if you're buried deep inside your project directories' treep

I haven't seen the issue in opened task but if it was already proposed, sorry for the duplicate.

If this request is new and people of this project thinks it's a "newbie-ready" task, I'm interested in implementing it

Have you tried using cargo clean as-is? It should exist today (on an up-to-date cargo)

[allan-simon]

indeed it works (wasnt implemented last time i tried), however it's not advertized in the help , cargo and cargo -h only display two commands:

• build
• test

[alexcrichton]

It sounds like you have a quite old cargo, have you tried updating?

[allan-simon]

:/ ok seems the ubuntu ppa for cargo does not receive as much love as the rust one, i will update and keep you updated (so as my cargo binary)

No problem! I'm going to close this for now as this is implemented, but feel free to reopen if there are some needed improvements to it!
