Several other features are planned but I haven’t got the time to implement or improve them, including: (in no particular order)

If you wish to contribute to feature 3, 4 and 5, please do contact me via Github issue before doing it.

The documentation files themselves are downloaded to your disk when doc-browser --install-devdocs, doc-browser --install-dash or doc-browser --install-hoogle is invoked, however, to display the documentation, some additional Cascading Style Sh*t or JavaScript files are needed, some of these are not packaged with the documentation files.

Create the file XDG_CONFIG/doc-browser/config.yaml and edit it.

The file is in YAML format, configurable keys and documentations can be found at:

You can interact with this application using HTTP requests.

API documentation can be found at:

As can be seen from the below (slighly outdated) benchmark, it takes less than 50ms to search through 39,499 entries.

This application is written by incomplete@aixon.co, and licensed under MPL-2.0.

You can use the icon.svg in the root of this repository as the icon of this application. Permission is needed if you plan to use it for other purposes.

Many thanks to Thibaut Courouble and other contributors of DevDocs, without their work, this application wouldn’t be possible:

Many thanks to Neil Mitchell for the great Hoogle. The Hoogle support receives helps from him. This application also ships with a little code from the Hoogle project, the modified code is licensed under the BSD license.

Many thanks to Bogdan Popescu for allowing me to use Dash’s docset. This application also ships with icons from the Dash-iOS project. If you are using Mac, please consider Dash.

Problem: On KDE, Ctrl+/ is taking too long to open the browser.

Solution: This application uses xdg-open to open the browser. Try this workaround.

Problem: The font in the documentation is too big or too small.

Solution: Tweak the configuration WebEngineZoomFactor, see the Configuration section for instruction.

Problem: HTTP summon interface doesn’t bring the window to front

Solution: Try the section Additional settings for Linux described in here.

Problem: (China users only) Installation of docsets hangs/open documentation shows blank screen.

Solution: devdocs.io or cloudflare.com is blocked by GFW, please use a VPN.

Problem: Install/uninstall some Dash docsets reports error.

Solution: If a docset has / in its name or version, (many Dash docsets do), the installation or uninstallation may not work. This problem is known from the begining, it’s just that I haven’t got time to fix it properly (without introducing un-upgradable changes). Solution: wait for me to fix it :(

Q: Why does this application display at most 27 matches?

A: If your desired match is not in the top 27 matches, then there is probably something wrong with the search algorithm.

Q: Why does this application display at most 10 tabs?

A: If too many tabs are displayed, the tab title would be hard to see on many monitors. Instead of wanting more tabs, try open another instance of this application. The number of maximum tabs will be configurable in future versions, so you can benefit from a large monitor.
