manpm

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

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.

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.
