fzf-csh

C shell (csh) history support for fzf command line fuzzy finder.
Works with tcsh.

how to use

• clone the repository or download these two files: fzf-csh.csh and fzf-csh-impl.csh
• source fzf-csh.csh in your .cshrc configuration file:

if ( -r "/path/to/fzf-csh.csh" ) then
    source /path/to/fzf-csh.csh
endif

• copy fzf-csh-impl.sh somewhere in the $PATH and make sure it is executable (chmod +x).

If you're lucky, after logging out and then in, pressing Ctrl + R will open the fzf list with command history. Press Enter to put the selected history item on the command line.

Note that you have to press Ctrl + R first and then start typing something to filter the history. Doing the other way around - typing and then pressing Ctrl + R - will not take into account what have already been typed.

fzf-csh requires some temporary writable directory to work, and by default it uses $HOME. If $HOME is not writable or you want to use another directory, set its path in the $FZF_CSH_TMP_DIR environment variable before including fzf-csh.csh, e.g.:

if ( -r "/path/to/fzf-csh.csh" ) then
    setenv FZF_CSH_TMP_DIR /tmp
    source /path/to/fzf-csh.csh
endif

compatibility

Tested with fzf 0.33 and 0.34 on FreeBSD 13.1, so at the moment fzf-csh should work with tcsh shell (6.22.04) from the FreeBSD base system.

Also tested on Ununtu Linux 20.04 LTS ("Focal Fossa"). Note that there are two csh packages: csh (installs /bin/bsd-csh) and tcsh (installs /bin/tcsh). The former will not work, make sure to install tcsh or, if both are installed, run update-alternatives --config csh command and select tcsh when prompted.
