fzf-csh

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

how to use

• clone the repository:

git clone https://github.com/graahnul-grom/fzf-csh.git

• 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.csh and fzf-csh-find.sh somewhere in the $PATH and make them executable (chmod +x).

After logging out and then in, pressing Ctrl + R will open the fzf list with command history. Press Enter to put 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

file name completion

In addition to history, file name completion support has been added recently. Press Ctrl + T to open a list with (regular) files/dirs names found under the current directory. Paths like .git/, .svn/, and those located on other file systems are excluded by default. See fzf-csh-find.sh for the find(1) command used.

compatibility

Tested with fzf 0.33 - 0.38 on FreeBSD 13, so at the moment fzf-csh should work with tcsh shell (6.22.04 - echo $tcsh) from the FreeBSD base system.

Also tested on Ubuntu 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 the tcsh one or, if both are installed, run update-alternatives --config csh command and select tcsh when prompted.
