SCM Breeze feature - Shortcut to files from ls, and wrap common shell commands

[ndbroadbent]

I've just finished some work that integrates the numeric shortcuts into the rest of your shell commands.
So, as well as shortcuts for files in git status, you can now also get shortcuts to files from the output of ls. I was using ll as an alias for ls -l, but now I've turned ll into an SCM Breeze function that gives the following output:

After typing ll, you can use any of the following commands with the numbered shortcuts:

• vim, emacs, gedit, cat, rm, cp, mv, ln, ls, cd

For example, let's say you wanted display the contents of scmbrc.example - now you can just type cat 11.

I've tested it out as much as I can, but I'm sure we will run into some strange issues at some point.
If you would like to help test it, please update scm_breeze from the master branch and let me know how it works for you.
Also let me know if you have any suggestions for commands that should be added to the list above.

Thanks!

Very interesting idea! I'll see if anything breaks for me.

bash: $'34mlib\E[0m': command not found

Same thing is happening with vim. If this means anything cat worked as expected.

Also when my shell opens I'm now told

which: no cd in (all my paths)

Hey, thanks so much for your help! I've pushed some fixes for shell builtins, and ensured colors are stripped from ls with the color=never problem. Can you please update and try again?

[ghthor]

Working great. This is awesome!

[ndbroadbent]

Good to hear! Thanks!

I like this feature and am using it. BTW, do you think it will be a good idea to have the numeric shortcut for git branch and git checkout? I normally have a bunch of branches, switching back and forth is tedious even with the aid of bash completion. I would like to type git branch or gb to list the local branches labeled by numbers and then type gco 1 to change to the first branch. Thanks!

[ndbroadbent]

Hey, I think that's a great idea, and I've just pushed support for git branch shortcuts up to the master branch. Instead of running git pull this time, please run update_scm_breeze, which will also add the new aliases to your git.scmbrc config file.

Numbered shortcuts are now shown for git branch, and the following aliases for branch commands:

• gb = git branch
• gba = git branch -a (shows all branches from remotes)
• gbm = git branch -m (move a git branch (rename) )
• gbd = git branch -D (delete a branch)

All of these aliases work with the numbers from git branch, so you type things like: gco 1, gbd 2, gbm 3 new_branch_name, etc.

Thanks for this idea, it really is useful!

Note: You should be able to run the update_scm_breeze command from anywhere. SCM Breeze sets it up as a function when it's loaded.

I have my customized cd listed below which conflicts with scm_breezed cd

cd() {
   MAX=10
   LEN=${#DIRSTACK[@]}

   if [ $# -eq 0 ] || [ "$1" = "-" ]; then
      builtin cd "$@"
      pushd -n $OLDPWD > /dev/null
   else
      local len=`expr match "$1" '^-[0-9]*'`
      if [ $len -ge 2 ]; then
         builtin pushd +${1:1} > /dev/null
      else
         pushd "$@" > /dev/null || return 1
      fi
   fi

   if [ $LEN -gt 1 ]; then
      for i in `seq 1 $LEN`; do
         eval p=~$i
         if [ "$p" = "$PWD" ]; then
            popd -n +$i > /dev/null
            break
         fi
      done
   fi

   if [ $LEN -ge $MAX ]; then
      popd -n -0 > /dev/null
   fi

   # Default action: list files
   ls
}

Can I specify which bash commands to be scm_breezed? I definitely like my vim to be scm_breezed but might not others. Normally I use mc (midnight-commander) to move around and to do common file operations. I have noticed that in .git.scmrc there is a line that I can comment out to disable all alias.

[ndbroadbent]

Ah, I see, you are already using numbers for your custom cd.
Sure, I just pushed a change so you can now edit the commands in your git.scmbrc file, and remove 'cd' from the list.
Again, you'll need to update using update_scm_breeze

Awesome! Thank you so much!
