zsh-bdi
Quickly go back to a specific ancestor directory instead of typing cd ../../.. redundantly.
This is a reimplementation of Tarrasch's zsh-bd. It comes with less code, more zsh builtin functionality, and a slightly improved ancestor choosing algorithm.
Hint
To get the feel of setopt autocd back, add alias ..=bdi to your zshrc.
After that you can go dot-only. .. ......
Usage
bdi [OPTIONS] PATTERN
Pattern has to follow the notation described below.
Installation
Use your preferred zsh plugin manager. For installation instructions see their sites.
For manual installation download bdi and add autoload -Uz ${LOCATION}/bdi in your zshrc.
For completions download _bdi.zsh and add the directory where the file is located to $fpath.
Pattern notation
Which notations will be considered can be specified with the -n-option.
When the passed pattern does not meet the notation requirements it will be
ignored and the next will be tested.
dot
Treat pattern of repeatedly used periods as amount_of_dots+1 directories. If the amount of dots is greater than the amount of ancestors, the resulting directory is /.
empty
Treat a missing pattern as one directory up.
number
Treat pattern as a number and go amount directories up. If number is 0 or greater than the amount of possible directories the result will be /.
word(s)
Treat the pattern as a subsequence of a directory. If there are more than one, bdi chooses the closest to pwd. Exact matches are prioritized.
Default order of finding the best matching ancestor
The order can be customized with the -n-option.
-
If no arguments are given, go one directory back. (empty)
-
Find ancestor that matches the passed pattern. (word)
-
Find ancestor that begins with the passed pattern. (word)
-
If the passed pattern is a sequence of dots
$\.+^, go amount of dots +1 ancestors back. (dot) -
If the passed pattern is a number, go number directories back. 0 is a shortcut to /. (number)
-
fail!
