I did a code that uses custom literals to allow indexing arrays with ordinals (1st, 2nd, 3rd), all at compile time. Additionally _st works only with 1, _nd only with 2, _rd only with 3. Zero and negative numbers are also not supported and fail compilation.

I created a very simple script that shows the history usage of your shell. Should work with bash and fish shells.

This basically goes through the history and counts the command names. So all of git push, git pull, etc will count as just git.

Example output:

847 pacman 296 cd 206 git 203 time 180 vim 172 awk 166 aur 142 strace 141 cat 125 ls Total commands: 7008 Unique commands: 753

ifn't

    % proc ifn't {cond cmds} {if {!$cond} {uplevel $cmds}}

    12
    % ifn't true {puts 12}
    %
