| 1 | | - | ## Overview |
| 2 | | - | |
| 3 | | - | LHelp is the default help viewer for Lazarus. It displays CHM help files. |
| 4 | | - | |
| 5 | | - | The screenshot below shows Lazarus LCL context-sensitive help displayed in LHelp:  |
| 6 | | - | |
| 7 | | - | ## Operation |
| 8 | | - | |
| 9 | | - | LHelp can be run stand-alone and used to open/view CHM files like a regular CHM viewer. |
| 10 | | - | |
| 11 | | - | It can also be invoked and controlled by the Lazarus IDE to display context-sensitive help etc. For that, it uses the [[Help protocol]]. |
| 12 | | - | |
| 13 | | - | ## Internals |
| 14 | | - | |
| 15 | | - | LHelp uses the [[chm]] package provided by FPC to read CHM files, table of contents (TOC), and full text search index. |
| 16 | | - | |
| 17 | | - | ## Limitations |
| 18 | | - | |
| 19 | | - | - LHelp cannot search on words containing the search term. This is similar to the behaviour of the Windows help viewer. Implementing this would require traversing the entire full-text search tree, parsing results and then displaying which would probably take a lot of time. |
| 20 | | - | - Known bugs: See bug reports on the bug tracker with tag LHelp, LHelp in the description etc. |
