Protocol handler integration

Protocol handler integration allows you to control DevDocs through scripts. For example:

$ osascript -e 'tell application "DevDocs" to open location "devdocs-macos://search?doc=rails&term=stro"'

... will tell DevDocs to open a new window and search the Rails documentation for the term stro.

The app supports the following commands. When required parameters are not supplied, the command is ignored.


This is for launching a search query in a new window.

Query Parameter Required Description
term Yes The search term, eg. stro
doc No Documentation scope, eg. rails


This opens a new window.

http:// and https://

DevDocs will open a new window only for URLs on the devdocs.io domain. For example:

$ osascript -e 'tell application "DevDocs" to open location "https://devdocs.io/#q=rails+stro"'

Other domains are ignored.
