Documentation

Alist telling Info-mode where manuals are accessible online.

Each element of this list has the form (MANUALs . URL-SPEC). MANUALs represents the name of one or more manuals. It can either be a string or a list of strings. URL-SPEC can be a string in which the substring "%m" will be expanded to the manual-name and "%n" to the node-name. "%e" will expand to the URL-encoded node-name, including the .html extension; in case of the Top node, it will expand to the empty string. (The URL-encoding of the node-name mimics GNU Texinfo, as documented at Info node (texinfo)HTML Xref Node Name Expansion.) Alternatively, URL-SPEC can be a function which is given manual-name, node-name and URL-encoded node-name as arguments, and is expected to return the corresponding URL as a string.

This variable particularly affects the command Info-goto-node-web, which see.

The default value of this variable refers to the official, HTTPS-accessible HTML-representations of all manuals that Emacs includes. These URLs refer to the most recently released version of Emacs, disregarding the version of the running Emacs. In other words, the content of your local Info node and the associated online node may differ. The resource represented by the generated URL may even be not found by the gnu.org server.

This variable was added, or its default value changed, in Emacs 30.1.

Probably introduced at or before Emacs version 30.1.
