[GSoC PATCH v7 0/5] repo: add new command for retrieving repository info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi!

These are the changes of this 7th version of `git repo`:

- The tests were refactored (thanks Eric for your careful revision!)

- The documentation has been improved: now it is a little more
  descriptive about the keys. I'm also including more information about
  the values

- The documentation now contains examples

- If an invalid key is requested, the command fails, however, now it
  returns all the valid fields that were requested

- Now, I'm using `quote_c_style` in the key=value format

Thanks!

Range-diff versus v6:
