Search API docs offline, in your terminal or browser

dasht is a collection of shell scripts for searching, browsing, and managing API documentation (in the form of 150+ offline documentation sets, courtesy of Dash for OS X) all from the comfort of your own terminal!

The name "dasht" is a portmanteau of Dash and the letter "t", for terminal. Etymologically, "dasht" is Persian for plain, as in an flat expanse of land, which aptly characterizes the terminal environment where everything is text.

Features

You never have to leave your terminal!
Local search engine for web browsers.
Keep Dash docsets anywhere you like.

Dependencies

Required:

POSIX environment (Linux, BSD, etc.)

sqlite3 to search inside Dash docsets

Optional:

wget to download docsets from Dash

w3m to display dasht(1) search results

socat for dasht-server(1) search engine

gawk for dasht-server(1) search engine

Development:

binman and md2man to build manual pages
```
  gem install binman md2man
```

Installation

Using a package manager:

Manually, on any system:

Download a stable release or clone this Git repository.

Add the bin/ folder to your PATH environment variable:

export PATH=$PATH:location_where_you_cloned_or_downloaded_dasht/bin

Add the man/ folder to your MANPATH environment variable:

export MANPATH=location_where_you_cloned_or_downloaded_dasht/man:$MANPATH

Vim integration

Use the vim-dasht plugin for (Neo)Vim.

ZSH integration

Source this file in ZSH to activate TAB completion for dasht:

source location_where_you_cloned_or_downloaded_dasht/etc/zsh/completions.zsh

Or simply add the completions/ directory to your ZSH $fpath if you've already set up ZSH's completion system elsewhere:

fpath+=location_where_you_cloned_or_downloaded_dasht/etc/zsh/completions/

Usage

First, install some docsets using dasht-docsets-install(1):

dasht-docsets-install bash

Next, perform a direct search from the terminal using dasht(1):

dasht 'c - x'

Then, repeat the search in a web browser using dasht-server(1):

dasht-server

You are now ready to use dasht! Read the manuals below to learn even more.

Manuals

You can browse the manuals online at https://sunaku.github.io/dasht/man/.
If you set $MANPATH or installed from a package manager, run man dasht.
Else, run man -M location_where_you_cloned_or_downloaded_dasht/man dasht.

Configuration

You may optionally configure the DASHT_DOCSETS_DIR environment variable, which defines the filesystem location where your Dash docsets are installed. If undefined, its value is assumed to be $XDG_DATA_HOME/dasht/docsets/ or, if XDG_DATA_HOME is also undefined, $HOME/.local/share/dasht/docsets/.

You may optionally configure the DASHT_CACHE_DIR environment variable, which defines the filesystem location where download links are cached. If undefined, its value is assumed to be $XDG_CACHE_HOME/dasht/ or, if XDG_CACHE_HOME is also undefined, $HOME/.cache/dasht/.

Development

If you make changes to the embedded manual pages found in the comment headers at the top of script files in the bin/ directory, then remember to run the binman-rake command afterward to regenerate UNIX manual pages for packaging.
