lazarus/components/chmhelp

lhelp is a program written entirely using FreePascal and the LCL to read .chm help files.

This is a basic HOWTO for integrating lhelp into the Lazarus IDE.


1 ) Start Lazarus

2 ) Install Package:

    In the Components Menu choose "Open Package File"
    Browse to the lazarus/components/chmhelp/packages/idehelp directory and
    open "chmhelppkg.lpk"

3 ) Now click "Install".

4 ) Restart Lazarus(if it didn't automatically)

5 ) Open the lhelp project in lazarus/components/chmhelp/lhelp/lhelp.lpi
    Compile lhelp.

6 ) Configure the paths for the lhelp:

    From the Tools menu choose "Options"
    Change to Help / Help options.
    Change to the "Viewers" tab and select "CHM Help Viewer"

    HelpEXE:
    For the "HelpEXE" entry browse to the lazarus/components/chmhelp/lhelp/ folder 
    and select the lhelp executable.

    HelpFilesPath:
    This is the directory that contains the lcl.chm fcl.chm and rtl.chm files.
    You can download them from the download page of www.lazarus.freepascal.org.

    HelpLabel Name and Tag do not need to be altered.
    The HelpLabel is the name of the named pipe that lazarus will use to communicate with lhelp.

7 ) Configure the DataBases

    Choose the DataBases tab.

    RTLUnits:
    this should be "rtl.chm://"
    FCLUnits:
    this should be "fcl.chm://"
    LCLUnits:
    this should be "lcl.chm://"

    NOTE if you have only a single lcl-fcl-rtl.chm file then paths become:
    "lcl-fcl-rtl.chm://rtl/"
    "lcl-fcl-rtl.chm://fcl/"
    "lcl-fcl-rtl.chm://lcl/"

Now close this window and check out the integrated help :)

Enjoy
