18.10 .doc

The .doc command is used to display this manual in poke’s REPL. The syntax is:

.doc [node]

where node is an optional parameter which indicates the chapter or section at which the manual should be opened.

This command uses whatever documentation viewer configured using .set doc-viewer whose valid options are either info and less.

Unless doc-viewer is set to less, this command uses the info program (The GNU Texinfo Manual) to interactively present the manual. If info is not installed, then less is tried next.

When using less to display the documentation, the entry in the Table of Contents corresponding to the requested entry is highlighted. Just press / and then RET to jump to the corresponding section in the manual.

If neither info nor less are installed, the .doc command will fail. If poke is not running interactively then .doc does nothing.
