manpm

Shows the relevant part of NPM module's README file right in your terminal

NPM

manpm alternate CI semantic-release npm checklist CHECKLIST.md

Badge

If you module has API well-described in the README, and manpm <text> works well, consider adding the following manpm compatible badge to your README. Here is the markdown for both variants: words or unicode symbols

[![manpm](https://img.shields.io/badge/manpm-compatible-3399ff.svg)](https://github.com/bahmutov/manpm)
[![alternate](https://img.shields.io/badge/manpm-%E2%9C%93-3399ff.svg)](https://github.com/bahmutov/manpm)

Install

npm install -g manpm

Show the entire README from a package or github repo

You can give NPM package name (like manpm), GitHub user / repo pair (like bahmutov/manpm) or full GitHub url (like https://github.com/bahmutov/object-fitter or git@github.com:bahmutov/object-fitter.git).

manpm <package name | github repo>

For example manpm email-regex will render the README from email-regex package in you terminal

Show part of the readme

manpm <package name> [optional search text inside README]

If search text is provided, only a section of the README file with that text (if found) will be displayed.

manpm search section

The following search features are implemented

  • find exact match in the section heading text
  • fuzzy text match in the section heading text
  • find exact match in the section body
  • fuzzy text match in the section body

I am still looking for a library capable of fuzzy text search. Maybe lunr?

Show and search local README

Sometimes you just want to find a section in the local README file, right in the current directory.

manpm . [optional search text]

Example: showing ES6 docs

There is a great GitHub repo ES6 Overview in 350 Bullet Points hosted at https://github.com/bevacqua/es6. Let us see how we can info for WeakSets

$ manpm bevacqua/es6 weaksets
# WeakSets

    * WeakSet is sort of a cross-breed between Set and WeakMap
    * A WeakSet is a set that can't be iterated and doesn't have enumeration methods
    * WeakSet values must be reference types
    * WeakSet may be useful for a metadata table indicating whether a reference is actively in use or not
    * Read ES6 WeakSets in Depth (https://ponyfoo.com/articles/es6-weakmaps-sets-and-weaksets-in-depth#es6-weaksets)

<sup>(back to table of contents) (#table-of-contents)</sup>

I added an alias to manpm bevacqua/es6 command to my shell alias file for convenience

$ echo 'alias es6-docs="manpm bevacqua/es6"' >> ~/.alias
source ~/.alias
es6-docs weaksets
es6-docs array

Example: showing ES6 features

Another great succint overview of ES6 features is in lukehoban/es6features. Let us add an alias

echo 'alias es6-features="manpm lukehoban/es6features"' >> ~/.alias
source ~/.alias

Let us look up the binary notation in ES6

es6-features binary
### Binary and Octal Literals
Two new numeric literal forms are added for binary (b) and octal (o).
    0b111110111 === 503 // true
    0o767 === 503 // true

Pipe through less | more

You can pipe the output of manpm through "less" or "more" tools - but you will lose the Markdown highlighting.

manpm <package name> | less
manpm <package name> | more

Advanced

If there are problems and manpm is not working as expected, you can see the debug output. Just run the tool with DEBUG=manpm manpm ... environment setting.

$ DEBUG=manpm manpm object-fitter
manpm fetching README for package +0ms object-fitter

Good testing commands:

DEBUG=manpm npm run example-es6-docs

Inspired by the following tools

I wanted something a little more API friendly, like finding and showing a README section that talked about a specific API method for example.
