zsh-bench-hist

This application processes the output of zsh-bench --raw to visualize it as ASCII histograms.

Usage

zsh-bench --raw --iters 100 | python3 zsh-bench-hist.py --bin-count 10

Note: As benchmark with many iterations might take a while, it may be useful to send the output of zsh-bench --raw to a file and process it later if you want to experiment with the --bin-count option:

zsh-bench --raw --iters 100 > zsh-bench-1.log
cat zsh-bench-1.log | python3 zsh-bench-hist.py --bin-count 10
