Comparing C++ range libraries for filter+reverse case with non-trivial lambda (dev.to)
 

I wrote a blog post comparing several range libraries for a case that is doing filter with non-trivial lambda and then reverse.

I used hyperfine CLI tool to measure startup and shutdown times of several code interpreters in c/[email protected]

I added bun and deno. Updated results are on the github page. Deno is similar to node, bun takes much less time.

Index arrays with ordinals instead of integers with custom literals in c/[email protected]
[–] [email protected] 2 points 8 months ago (1 children)

It should be easy to edit the existing code to add support for i18n, but there's probably no way to make in generic (except for macros).

Yeah, that was basically it.

There's no purpose really. It was more of "wonder if I can" and also nice way to learn custom literals.

Index arrays with ordinals instead of integers with custom literals (programming.dev)
 

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.

histat - a simple history stats (github.com)
 

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 in c/[email protected]

I can actually define this in TCL:

% proc ifn't {cond cmds} {if {!$cond} {uplevel $cmds}}
% ifn't false {puts 12}
12
% ifn't true {puts 12}
%
