Maybe someone can help with a few issues around LHelp in the IDE:

1) When LHelp opens (regardless if opens with Tools->CHM-Help or F1 context help) it opens with 11 tabs.
Some of them have a caption, some of them are [unknown]. The [unknown] ones come up with an error message "ms-its:xyz.chm::/index.html not found!"

2) One of [unknown] tabs is completely empty:
"ms-its:toc.chm::/index.html not found!"

3) There are two lcl tabs. One show a message "Loaded: ms-its:lcl.chm::/index.html in ... ms", the other one doesn't show a load message.

3) There's no possibility to search in all files simultanously. May be this is the missing toc.chm::/index.html?

4) The first context search is a racing car. All following context searches are a bicycle. Time for a coffee.

I'd like to check for this.

Is there any documentation about the structure of the chm files reagarding the missing index.html?
What's the meaning of the database definition fields in Tools-Settins-Help? There are entries for 8 databases. What about the missing ones.
How does the IDE calls LHelp?

Any ideas?

I have your questions too for a long time but i'm just a hobbyist so i can live these lack of knowledge.

Hello Rolf,

1) When LHelp opens (regardless if opens with Tools->CHM-Help or F1 context help) it opens with 11 tabs. Some of them have a caption, some of them are [unknown]. The [unknown] ones come up with an error message "ms-its:xyz.chm::/index.html not found!"

That is my TODO for lHelp, You can get some of last patches here https://bugs.freepascal.org/view.php?id=38250
, but it not in a repo now.

2) One of [unknown] tabs is completely empty: "ms-its:toc.chm::/index.html not found!"

I don`t what about it. I can get a new chm`s here for try. https://forum.lazarus.freepascal.org/index.php/topic,53114.0.html It is without a structural errors.

3) There are two lcl tabs. One show a message "Loaded: ms-its:lcl.chm::/index.html in ... ms", the other one doesn't show a load message.

I think I am going fix that later.

3) There's no possibility to search in all files simultanously. May be this is the missing toc.chm::/index.html?

Patch sub 1 is not applied yet.

4) The first context search is a racing car. All following context searches are a bicycle. Time for a coffee.

Toc.chm is a master index of the CHMs, with a hardcoded list of known chms.

It is as meant to function as default page (TOC) of the FPC textmode IDE, to provide a way to navigate to each CHM's toc.

I don't think this is needed for Lazarus, as each helpfile has its own tab and thus place to show the TOC.

Hi Andy

I've patched LHelp.exe with lhelp_index_combine_04.patch.

The "unknown" tab issue is partly solved. Now all tabs have a caption. There's one strange behaviour:
[FPDoc Documentation], [Programmer' Guide], [Reference Guide] and [User's Guide] doesn't show the default page if LHelp is called from the IDE via Help/CHM help or via context F1. They show an empty page. But it shows the default page if I open prog.chm for example in LHelp via File/Open.

An other difference: Calling LHelp via context F1 doesn't show the toc.  Tested with F1 on "TForm".

There is not a final version, I work at that yet. The main change is a full merged indexes (Binary index and FTSI) for an one page mode.

Hi Rolf,
I have placed the next version of patch and created a branch on a forum for discussion
