🚀 enhancd v2 is ...
A next-generation
cdcommand with an interactive filter ✨
cd command is one of the frequently used commands.
Nevertheless, it is not so easy to handle unfortunately. A directory path given as an argument to cd command must be a valid path that exists and is able to resolve. In other words, you cannot pass a partial path such as "dir" (you are in /home/lisa, dir is /home/lisa/work/dir) to cd command.
The new cd command called "enhancd" enhanced the flexibility and usability for a user. enhancd will memorize all directories visited by a user and use it for the pathname resolution. If the log of enhancd have more than one directory path with the same name, enhancd will pass the candidate directories list to the filter within the ENHANCD_FILTER environment variable in order to narrow it down to one directory.
Thanks to this mechanism, the user can intuitively and easily change the directory you want to go.
DEMO:
Features- Go to the visited directory in the past
- Easy to filter, using your favorite filter
- Work on Bash and Zsh (Full compatible)
- Go back to a specific parent directory like zsh-bd
- Fuzzy search in a similar name directory
- Support standard input (
echo $HOME | cdis acceptable) - Custom options (user-defined option is acceptable)
You can fuzzy-search a directory name you want to run cd. For example, a word "text" is expand to "test" and "txt".
Under Zsh or Bourne shells such as sh and bash, you just source init.sh into your shell:
$ source ./init.shBecause enhancd functions must be executed in the context of the current shell, you should run something like above command.
The basic usage of the cd command that has been implemented by enhancd is the same as the normal builtin cd command.
$ cd [-|..] <directory>If no arguments are given, enhancd cd command will display a list of the directory you've visited once, encourage you to filter the directory that you want to move.
$ cd

It is likely the only environment variable you'll need to set when starting enhancd.
$ ENHANCD_FILTER=peco; export ENHANCD_FILTERSince the $ENHANCD_FILTER variable can be a list, enhancd will use $ENHANCD_FILTER to mean the first element unless otherwise specified.
$ ENHANCD_FILTER=fzy:fzf:peco
$ export ENHANCD_FILTERAlso,
Hyphen (`-`)
When enhancd takes a hyphen (-) string as an argument, it searchs from the last 10 directory items in the log. With it, you can search easily the directory you used last.
$ cd -
/home/lisa/Dropbox/etc/dotfiles
/home/lisa/Dropbox

> _ Then, since the current directory will be delete from the candidate, you just press Enter key to return to the previous directory after type cd - ($PWD is /home/lisa, $OLDPWD is /home/lisa/src/github.com/b4b4r07/portfolio).
Double-dot (`..`)
From the beginning, .. means the directory's parent directory, that is, the directory that contains it. When enhancd takes a double-dot (..) string as an argument, it behaves like a zsh-bd plugin. In short, you can jump back to a specific directory, without doing cd ../../...
For example, when you are in /home/lisa/src/github.com/b4b4r07/enhancd, type cd .. in your terminal:
$ cd ..
/
home
lisa
src
github.com
> b4b4r07

> _When moving to the parent directory, the current directory is removed from the candidate.
🆕 v2.2.0~
You can make the option that you thought for your enhancd from 2.2.0 or above.
$ cd --help
usage: cd [OPTIONS] [dir]
OPTIONS:
-h, --help Show help message
-V, --version Show version information
-G, --ghq Filter ghq list
Those options are defined at config.ltsv. As it is written in this json, the user have to make a directory list file or script that generate the list like this script. Of cource, you can disable those options if you do not like it.
Give me a trial!

Install with zplug:
enhancd can be installed by adding following to your
.zshrcfile in the same function you're doing your otherzplug loadcalls in.$ zplug "b4b4r07/enhancd", use:init.sh -
Install with
git clone:$ git clone https://github.com/b4b4r07/enhancd $ source /path/to/enhancd/init.sh
ENHANCD_DIR
The ENHANCD_DIR variable is a base directory path. It defaults to ~/.enhancd.
ENHANCD_FILTER
-
What is ENHANCD_FILTER?
The ENHANCD_FILTER is an environment variable. It looks exactly like the PATH variable containing with many different filters such as peco concatenated using '
:'. -
How to set the ENHANCD_FILTER variable?
Setting the ENHANCD_FILTER variable is exactly like setting the PATH variable. For example:
$ export ENHANCD_FILTER="/usr/local/bin/peco:fzf:non-existing-filter"This above command will hold good till the session is closed. In order to make this change permanent, we need to put this command in the appropriate profile file. The ENHANCD_FILTER command in this example is set with 3 components:
/usr/local/bin/pecofollowed byfzfand thenot-existing-filter.enhancd narrows the ENHANCD_FILTER variable down to one. However, the command does not exist can not be the candidate.
Let us try to test this ENHANCD_FILTER variable.
$ cdIf cd command does not return error, the settings of ENHANCD_FILTER is success.
-
How to find the value of the ENHANCD_FILTER variable?
$ echo $ENHANCD_FILTER /usr/local/bin/peco:fzf:non-existing-filter
ENHANCD_COMMAND
The ENHANCD_COMMAND environment variable is to change the command name of enhancd cd. It defaults to cd.
When the command name is changed, you should set new command name to ENHANCD_COMMAND, export it and restart your shell (reload init.sh).
$ echo $ENHANCD_COMMAND
cd
$ export ENHANCD_COMMAND=ecd
$ source /path/to/init.shThe ENHANCD_COMMAND may only hold one command name. Thus, in the previous example, it is true that enhancd cd command name is ecd, but it is not cd (cd is turned into original builtin cd).
Besides putting a setting such as this one in your ~/.bash_profile or .zshenv would be a good idea:
ENHANCD_COMMAND=ecd; export ENHANCD_COMMANDENHANCD_DOT_SHOW_FULLPATH
The ENHANCD_DOT_SHOW_FULLPATH environment variable is to set whether to show the full path or not when executing Double-dot. It defaults to 0.
$ export ENHANCD_DOT_SHOW_FULLPATH=1
$ cd ..

> _ENHANCD_DISABLE_DOT
If you don't want to use the interactive filter, when specifing a double dot (..), you should set not zero value to $ENHANCD_DISABLE_DOT. Defaults to 0.
ENHANCD_DISABLE_HYPHEN
This option is similar to ENHANCD_DISABLE_DOT. Defaults to 0.
ENHANCD_DISABLE_HOME
If you don't want to use the interactive filter when you call cd without an argument, you can set any value but 0 for $ENHANCD_DISABLE_HOME. Defaults to 0.
ENHANCD_DOT_ARG
You can customize the double-dot (..) argument for enhancd by this environment variable.
Default is ...
If you set this variable any but .., it gives you the double-dot behavior with that argument; i.e. upward search of directory hierarchy.
Then cd .. changes current directory to parent directory without interactive filter.
In other words, you can keep original cd .. behavior by this option.
ENHANCD_HYPHEN_ARG
You can customize the hyphen (-) argument for enhancd by this environment variable.
Default is -.
If you set this variable any but -, it gives you the hyphen behavior with that argument; i.e. backward search of directory-change history.
Then cd - changes current directory to $OLDPWD without interactive filter.
In other words, you can keep original cd - behavior by this option.
ENHANCD_HYPHEN_NUM
You can customize the number of rows by "cd -"
Default is 10.
This is passed to head comand as -n option.
ENHANCD_HOME_ARG
You can customize to trigger the argumentless cd behavior by giving the string specified by this environment variable as an argument.
Default is empty string.
If you set this variable any but empty string, it gives you the behavior of cd with no argument; i.e. backward search of the whole directory-change history.
Then cd with no argument changes current directory to $HOME without interactive filter.
In other words, you can keep original behavior of cd with no argument by this option.
ENHANCD_HOOK_AFTER_CD
Default is empty. You can run any commands after changing directory with enhancd (e.g. ls: like cd && ls).
ENHANCD_USE_FUZZY_MATCH
Default is 1 (enable). See #33.
