linesieve 1.0a5

An unholy blend of grep, sed, and awk, with very specific features.

This is my text munging tool. There are many like it, but this one is mine.

linesieve is an unholy blend of grep, sed, and awk, with very specific features, born out of spite.

Features

• line-oriented
• section-oriented
  • show only matching sections
  • show the failing section
• match/sub with the full power of re
• chain filters into pipelines
• colors!
• TODO: specific filters

Examples

Get all options used by any git command

Note that some of the man pages contain multiple OPTIONS sections (e.g. ADVANCED OPTIONS).

export MANWIDTH=9999

function man-section {
    col -b | python3 -m linesieve -s '^[A-Z ()-]+$' show "$@"
}

man git \
| man-section COMMANDS match -o '^ +(git-\w+)' \
| cat - <( echo git ) \
| sort | uniq \
| xargs -n1 man \
| man-section OPTIONS match -o '^ +(-.*)' \
    sub -F -- '--[no-]' '--' \
    sub -F -- '--no-' '--' \
| sort -dfu

Output:

-/ <path>

-a, --all
-A, --all, --ignore-removal
-a, --annotate

--autosquash, --autosquash
