cd-bookmarks.sh - add bookmarks to cd (in bash)

This (ab)uses the CDPATH functionality of bash to add bookmark functionality, with tab completion, to the built in cd command. It also offers optional pushd / popd integration.

Why: CDPATH is cool, but it's useability really sucks. Turning it on and off, or using aliases, or other attempts to tame it just didn't give me the desired result. By dynamically setting CDPATH we can have as many bookmarks as we want, and only use them when we explicitly ask for it.

Under the hood it's all just the normal cd command (with some pushd and popd. All your favorite flags like -P or -@ still get passed along.

Tab completion is a slightly modified version of the normal cd completion.

export cd_includebookmarks=1 includes the bookmarks in tab completion for the first argument.

export cd_includebookmarks=2 will show ONLY bookmarks in tab completion for the first argument

Usage:

cd -b                   # list bookmarks

cd [-b] bookmark        # cd to a bookmark

cd my_bookmark subdir
cd -b my_bookmark subdir
cd subdir -b my_bookmark # cd to a directory "subdir" below bookmark "my_bookmark"

Bookmark management:

cd -a [name] [dir]      # add/update bookmark (dir defaults to current dir)
cd -a -s [name] [dir]   # add/update bookmark and save to disk
cd -S name              # save bookmark for current dir (sugar for -a -s)

# with pushd enabled
~$ cd /dir1
/dir1$ cd /dir2
/dir2$ cd /dir3
/dir3$ cd -p
/dir2$ cd -p
/dir1$ cd -p
~$

Setup:

Load cd-bookmarks, in .bashrc or elsewhere:

source /path/to/cd-bookmarks.sh

And set your bookmarks (in your shell startup or interactively):

cd -a project1 /path/to/bookmark     # in-session bookmark
cd -a -s project2 /other/bookmark    # persistent bookmark (saved to disk)
cd -S local_tmp                      # save current directory as "local_tmp"

You can also set them directly in bash if you prefer:

cd_bookmarks[project1]=/path/to/bookmark
cd_bookmarks[project2]=/other/bookmark
cd_bookmarks[both_projects]=/path/to/bookmark:/other/bookmark
cd_bookmarks[local_tmp]=~/.local/tmp

# Update the index after changing bookmarks
cd --update

The default bookmark is ., but you can change that if you want.

cd_bookmarks["default"]=.:~/work

You may optionally have it use pushd and add "cd -p" to call popd. Set cd_usepushd=1 (default) to enable, or cd_usepushd=0 to disable this behavior. These let you keep a history of the paths you have been in and return to them.

    cd -p # run "popd"
    cd -v # run "dirs -v"
    cd -c # run "dirs -c"

e.g.:
  ~$ cd mydir

  ~/mydir$ cd /usr/mydir2

  /usr/mydir2$ cd -p

  ~/mydir$ cd -p

  ~$
