Add rename-alias alias at alias management

[pachoyan]

Add rename alias:

Usage:

git rename-(local|global)-alias <alias existing name> <new alias name>

git rename-alias

• Choose Local or global to use --global or --local options
• First parameter <alias existing name> must be an existing alias.
• Second parameter <new alias name> must be an alias that does not exist.
• First parameter and second parameter must be different.
• There must be two parameters

Examples:

Success:

git rename-local-alias ci comm
git rename-global-alias ci comm

git rename-alias ci comm
Alias comm renamed to ci

Error:

git rename-local-alias any ci
Usage: git rename-alias <alias existing name> <new alias name>
The alias you are going to rename must exist and new name must not exist.

git rename-global-alias any ci
Usage: git rename-alias <alias existing name> <new alias name>
The alias you are going to rename must exist and new name must not exist.

git rename-alias any ci

I don't like that 'Alias … renamed'. Unix command-line commands are usually silent in case of success; you can add option -v to allow verbosity.

Other than that — interesting idea and good implementation!

[pachoyan]

I agree. I'm going to remove the success message.
Regard the verbosity option IMO is not need. What do you think?

Thanks!

[phdru]

Not needed IMO. Go on!

[pachoyan]

Success message removed.

Good work, thank you! Good code, good commit message, and good discussion.

@pachoyan How does the code distinguish a local alias and a global alias? (The git default is for the "alias" command to work on a local alias, not global. See the --local option and --global option.)

[pachoyan]

@joelparkerhenderson Actually it doesn't distinguish a local alias and a global, it is using always the --global option. In my next commit, I'm going to update that using the same as is doing in add-(local-global)-alias aliases.

So, in the next commit the usage would be:

• Local

  git rename-local-alias ci comm
  

• Global

  git rename-global-alias ci comm
