Zapparix

Zapparix is a thin layer on top of Zsh's hashed directories. It provides an Apparix-like experience, with persistent bookmarks that you create using bm. However, because they are hashed by Zsh, they are much more closely integrated with the shell.

You automatically get expansion on bookmarks anywhere that the shell expands filenames, and of course you get completion the way you configured it for the rest of Zsh. Also, the Zsh prompt expansion %~ understands hashed directories, so more than likely your prompt already knows about your bookmarks, with no more configuration needed.

Also, this means that you can use bookmarks together with shell globs (cp ~bm/**.{png,jpg} .).

Even though I say so myself, Zapparix provides some pretty nicely formatted output.

commands

command	effect
bm <mark>	bookmark the cwd with the name <mark>
bm	show all bookmarks
unbm <mark>	remove the bookmark <mark>
unbm	remove any bookmarks to the current directory
zapp	toggle Zapparix on or off. Controlled at startup by $ZAPPARIX_ACTIVE

Note that hashed directories are accessed by prefixing the hash ("bookmark name") with a tilde ~. So a sample session might look like this (this is a two-line zsh prompt):

 ~
❯ cd Documents

 ~/Documents
❯ bm doc
2a3
> hash -d doc=/home/izaak/Documents

 ~doc
❯ cd

 ~
❯ cd ~doc

 ~doc
❯ pwd
/home/izaak/Documents

 ~doc
❯

Here is a screenshot with colours, and a sample bookmark listing

There is a similar demo shell in zdemo/demo_zsh, which is about three lines of config setting up a prompt and sourcing zapparix.

See the source of apparix.zsh for maybe some more information.

Apparix

Directory bookmarking system. It used to be implemented in C, shipped with bash wrapper functions and completion code. This is now legacy, and should be retrieved from older commits (see the master branch).

The new pure shell implementation is in appari.sh.

However, in storing directories and bookmarks, it now uses a nice little serialisation system. The only consequence is that because of the way the bookmark escaping works, you are asked not to use the string __GOEDEL_PLACEHOLDER__ in any of your bookmarks or directories. If you really need to, you can set the environment variable $GOEDEL_PLACEHOLDER to some other suitable, Perl regex safe string before sourcing Apparix.

There is also a reference prompt that can talk to apparix, if you've got it set up, in prompt.bash. A minimal demo bashrc to call both is provided. You can try it out by running demo/demo_bash.

Similarly, I have included a prompt.zsh, zshrc and demo/demo_zsh. See below screenshot for what they should hopefully look like (in this screenshot I used tab completion. It's a little hard to see, but it's definitely there, in between the h and the ello\ world (which is to say, I didn't have to type any backslashes)).
