LHelp

Overview

Lhelp is the default help viewer for Lazarus. It displays CHM help files.

Operation

Lhelp can be run stand-alone and used to open/view CHM files like a regular CHM viewer.

It can also be invoked and controlled by the Lazarus IDE to display context-sensitive help etc. For that, it uses the Help protocol.

Internals

Lhelp uses the chm package provided by FPC to read CHM files, table of contents (TOC), and full text search index.
