Loading

| ?- logtalk_load(help(loader)).

Supported operating-systems

Currently, support is limited to Linux, macOS, and Windows.

On Windows, the start command must be available. On Linux, the xdg-open command must be available. On macOS, the command open is used.

This tool relies on the library portable operating-system access abstraction.

Known issues

On macOS, the open command used to open documentation URLs drops the anchors, thus preventing navigating to the specified position on the documentation page.

ECLiPSe defines a help prefix operator that forces wrapping this atom between parenthesis when sending messages to the tool. E.g. use (help)::help instead of help::help.

Other notes

All source files are indented using tabs (a common setting is a tab width equivalent to 4 spaces).
