See the wiki for extensive documentation, along with screenshots of Gollum's features.
Gollum is a simple wiki system built on top of Git. A Gollum Wiki is simply a git repository of a specific nature:
-
A Gollum repository's contents are human-editable text or markup files.
-
Pages may be organized into directories any way you choose.
-
Other content can also be included, for example images, PDFs and headers/footers for your pages.
-
Gollum pages:
- May be written in a variety of markups.
- Can be edited with your favourite editor (changes will be visible after committing) or with the built-in web interface.
- Can be displayed in all versions, reverted, etc.
-
Gollum strives to be compatible with GitHub and GitLab wikis.
- Just clone your GitHub/GitLab wiki and view and edit it locally!
-
Gollum supports advanced functionality like:
- Diagrams using Mermaid or PlantUML
- BibTeX and Citation support
- Annotations using CriticMarkup
- Mathematics via KaTeX or MathJax
- Macros
- Redirects
- RSS Feed of latest changes
- ...and more
Gollum runs both on Unix-like systems and on Windows.
Gollum runs either using 'normal' Ruby (MRI) or JRuby (Ruby on the Java Virtual Machine). On Windows, Gollum runs only using JRuby (either from source, or prebuilt).
On MRI, Gollum uses the rugged git library, while on JRuby/Java it utilizes the rjgit and JGit libraries. See here for more info.
Ruby is best installed either via RVM or a package manager of choice. Then simply:
gem install gollum
Installation examples for individual systems can be seen here.
To run, simply:
- Run:
gollum /path/to/wikiwhere/path/to/wikiis an initialized Git repository. - Open
http://localhost:4567in your browser.
See here for instructions on how to run Gollum via Docker.
The latest Release of Gollum will always contain a downloadable gollum.war file that can be directly executed on any system with a working Java installation:
java -jar gollum.war -S gollum <your-gollum-arguments-here>
See below for information on running Gollum from source, as a Rack app, and more.
Gollum allows using different markup languages on different wiki pages. It presently ships with support for the following markups:
You can easily activate support for other markups by installing additional renderers (any that are supported by github-markup):
- AsciiDoc --
gem install asciidoctor - Creole --
gem install creole - MediaWiki --
gem install wikicloth - Org --
gem install org-ruby - Pod -- requires Perl >= 5.10 (the
perlcommand must be available on your command line)- Lower versions should install
Pod::Simplefrom CPAN.
- Lower versions should install
- ReStructuredText -- requires python >= 3
- Note that Gollum will also need you to install
docutilsfor python
- Note that Gollum will also need you to install
- Textile --
gem install RedCloth
By default, Gollum ships with the kramdown gem to render Markdown. However, you can use any Markdown renderer supported by github-markup. This includes CommonMark support via the commonmarker gem. The first installed renderer from the list will be used (e.g., redcarpet will NOT be used if github/markdown is installed). Just gem install the renderer of your choice.
See here for instructions on how to use custom rendering gems and set custom options.
git clone https://github.com/gollum/gollumcd gollum[sudo] bundle installbundle exec bin/gollum- Open
http://localhost:4567in your browser.
Gollum can also be run with any rack-compatible web server. More on that over here.
Gollum can also be run alongside a CAS (Central Authentication Service) SSO (single sign-on) server. With a bit of tweaking, this adds basic user-support to Gollum. To see an example and an explanation, navigate over here.
Gollum can also be run as a service. More on that over here.
Gollum uses the environment variable APP_ENV primarily to control how the underlying Sinatra app behaves:
development– reload the app on every requestproduction– load the app only once
Gollum comes with the command line options listed below. Note that there are some additional 'minor' options to tweak Gollum's behaviour that do not have commandline options, but can be configured in config.rb.
| Option | Arguments | Description |
|---|---|---|
| --host | [HOST] | Specify the hostname or IP address to listen on. Default: '0.0.0.0'.1 |
| --port | [PORT] | Specify the port to bind Gollum with. Default: 4567. |
| --config | [FILE] | Specify path to Gollum's configuration file. |
| --ref | [REF] | Specify the git branch to serve. Default: master. |
| --bare | none | Tell Gollum that the git repository should be treated as bare. |
| --adapter | [ADAPTER] | Launch Gollum using a specific git adapter. Default: rugged.2 |
| --base-path | [PATH] | Specify the leading portion of all Gollum URLs (path info). Setting this to /wiki will make the wiki accessible under http://localhost:4567/wiki/. Default: /. |
| --page-file-dir | [PATH] | Specify the subdirectory for all pages. If set, Gollum will only serve pages from this directory and its subdirectories. Default: repository root. |
| --static, --no-static | none | Use static assets. Defaults to false in development/test, true in production/staging. |
| --assets | [PATH] | Set the path to look for static assets. |
| --css | none | Tell Gollum to inject custom CSS into each page. Uses custom.css from wiki root.3 |
| --js | none | Tell Gollum to inject custom JS into each page. Uses custom.js from wiki root.3 |
| --no-edit | none | Disable the feature of editing pages. |
| --allow-uploads | [MODE] | Enable file uploads. If set to dir, Gollum will store all uploads in the /uploads/ directory in repository root. If set to page, Gollum will store each upload at the currently edited page.4 |
| --math | [RENDERER] | Enable rendering of mathematical equations. Valid renderers: mathjax, katex. Default: katex. Add custom configuration for the renderer to math.config.js and commit it to the repo. |
| --critic-markup | none | Enable support for annotations using CriticMarkup. |
| --irb | none | Launch Gollum in "console mode", with a predefined API. |
| --h1-title | none | Tell Gollum to use the first <h1> as page title. |
| --no-display-metadata | none | Do not render metadata tables in pages. |
| --user-icons | [MODE] | Tell Gollum to use specific user icons for history view. Can be set to gravatar, identicon or none. Default: none. |
| --template-dir | [PATH] | Specify custom mustache template directory. Only overrides templates that exist in this directory. |
| --template-page | none | Use _Template in root as a template for new pages. Must be committed. |
| --emoji | none | Parse and interpret emoji tags (e.g. :heart:) except when the leading colon is backslashed (e.g. \:heart:). |
| --lenient-tag-lookup | none | Internal links resolve case-insensitively, will treat spaces as hyphens, and will match the first page found with a certain filename, anywhere in the repository. Provides compatibility with Gollum 4.x. |
| --help | none | Display the list of options on the command line. |
| --version | none | Display the current version of Gollum. |
| --versions | none | Display the current version of Gollum and auxiliary gems. |
Notes:
- The
0.0.0.0IP address allows remote access. Should you wish for Gollum to turn into a personal Wiki, use127.0.0.1. - Before using
--adapter, you should probably read this first. - When
--cssor--jsis used, respective files must be committed to your git repository or you will get a 302 redirect to the create a page. - Files can be uploaded simply by dragging and dropping them onto the editor's text area when
--allow-uploadsis used.
When --config option is used, certain inner parts of Gollum can be customized. This is used throughout our wiki for certain user-level alterations, among which customizing supported markups will probably stand out.
See here for documentation about settings configurable in config.rb.
All of the mentioned alterations and options work both for Gollum's config file (config.rb) and Rack's config file (config.ru).
