Wikiman is a universal offline documentation search engine. It can browse system manual pages, tldr-pages, the ArchWiki, Gentoo Wiki, FreeBSD documentation, and many other sources curated by DevDocs.

It provides an easy interface for browsing documentation without the need to be exact and connected to the internet. This is achieved by utilizing full-text search for wikis, partial name and description matching for man pages, and fuzzy filtering for search results.

Install from Arch Linux's extra repository:

pacman -S wikiman

# Optional: Enable ArchWiki
pacman -S arch-wiki-docs

If you are running Manjaro or another Arch-based distribution, download the latest .pkg.tar.zst package from Releases tab, and follow these instructions to add ArchWiki as a source.

sudo pacman -U wikiman*.pkg.tar.zst

Download latest .deb package from Releases tab.

sudo apt update
sudo apt install ./wikiman*.deb

Download latest .rpm package from Releases tab.

# Fedora
sudo dnf install wikiman*.rpm

# openSUSE (skip signature verification)
sudo zypper in wikiman*.rpm

Install textproc/wikiman from the Ports Collection:

portsnap auto
cd /usr/ports/textproc/wikiman
make install

Or download latest .txz package from Releases tab.

pkg install wikiman*.txz

Dependencies: man, fzf, ripgrep, awk, w3m, coreutils, parallel

# Clone from GitHub
git clone 'https://github.com/filiparag/wikiman'
cd ./wikiman

# Switch to latest stable release (optional)
git checkout $(git describe --tags | cut -d'-' -f1)

# Available targets: all, core, widgets, completions, config, docs
make all

# Only for BSD users: install to /usr/local instead of /usr
make local

# Install Wikiman
sudo make install

Wikiman uses GNU find and awk, so BSD users have to install findutils and gawk.

Currently available optional sources are:

• ArchWiki (arch)
• DevDocs (devdocs)
• FreeBSD Documentation (fbsd)
• Gentoo Wiki (gentoo)
• TLDR Pages (tldr)

Due to their large size, wikis don't come bundled with Wikiman. If you want to use them, you can download their latest snapshots using following commands.

# Download latest Makefile
curl -L 'https://raw.githubusercontent.com/filiparag/wikiman/master/Makefile' -o 'wikiman-makefile'

# Example for Linux: install ArchWiki and TLDR pages
make -f ./wikiman-makefile source-arch source-tldr
sudo make -f ./wikiman-makefile source-install
sudo make -f ./wikiman-makefile clean

# Example for BSD: install FreeBSD docs and TLDR pages
make -f ./wikiman-makefile source-fbsd source-tldr
make -f ./wikiman-makefile source-local # moves files from /usr to /usr/local
sudo make -f ./wikiman-makefile source-install
sudo make -f ./wikiman-makefile clean

After installation, they should be enabled automatically if sources configuration variable is empty.

To verify active sources, run:

wikiman -S

Usage: wikiman [OPTION]... [KEYWORD]...

If no keywords are provided, show all pages.

• -l search language(s)

  Default: en

• -s sources to use

  Default: (all available)

• -f fuzzy finder to use

  Default: fzf

• -q enable quick search mode

• -a enable AND operator mode

• -p disable quick result preview

• -k keep open after viewing a result

• -c show source column

• -H viewer for HTML pages

  Default: w3m

• -R print raw output

• -S list available sources and exit

• -W print widget code for specified shell and exit

• -v print version and exit

• -h display this help and exit

Wikiman can be launched using a shell key binding (default: Ctrl+F). Current command line buffer will be used as a search query.

Add appropriate line from below to your .bashrc-like configuration file to make the key binding permanent.

# bash
source /usr/share/wikiman/widgets/widget.bash

# fish
source /usr/share/wikiman/widgets/widget.fish

# zsh
source /usr/share/wikiman/widgets/widget.zsh

User configuration file is located at ~/.config/wikiman/wikiman.conf, and fallback system-wide configuration is /etc/wikiman.conf.

If you have set the XDG_CONFIG_HOME environment variable, user configuration will be looked up from there instead.

Example configuration file:

# Sources (if empty, use all available)
sources = man, arch

# Fuzzy finder
fuzzy_finder = sk

# Quick search mode (only by title)
quick_search = true

# Raw output (for developers)
raw_output = false

# Manpages language(s)
man_lang = en, pt

# Wiki language(s)
wiki_lang = zh-CN

# Show previews in TUI
tui_preview = false

# Keep open after viewing a result
tui_keep_open = true

# Show source column
tui_source_column = true

# Viewer for HTML pages
tui_html = xdg-open

To list available languages, run these commands:

# Man pages (excluding English)
find '/usr/share/man' -maxdepth 1 -type d -not -name 'man*' -printf '%P '

# ArchWiki
find '/usr/share/doc/arch-wiki/html' -maxdepth 1 -type d -printf '%P '

# FreeBSD Documentation
find '/usr/share/doc/freebsd-docs' -maxdepth 1 -type d -printf '%P '

# TLDR Pages
find '/usr/share/doc/tldr-pages' -maxdepth 1 -type d -printf '%P '

Wikiman is designed to be extensible: each source has it's module in sources/ directory. These modules are loaded as needed during runtime.

Source modules are POSIX compliant shell scripts. Wikiman calls their search function which reads $query and configuration variables, and prints results to STDOUT. variable with rows formatted as NAME\tLANG\tSOURCE\tPATH.

• NAME title of the page
• LANG two letter language code (can include locale)
• SOURCE source name
• PATH path to HTML file

When listing available sources, Wikiman will call module's info funcion which prints name, state, number of pages and path of the source.

If you create a source module useful to the general public, please share it using a pull request. Your pull request should contain:

• module script file sources/your-source.sh
• Makefile recipe source-your-source
• build script for the database snapshot build/sources/your-source.sh
• demo snapshot of the source database your-source-TIMESTAMP.source.tar.xz (optional)
• short description in the pull request's body

Other improvements are also welcome!
