About plugin

CHMDir adds support of ITSS/CHM file format (compiled HTML) to Total Commander, allows you to extract, search, pack, delete files in CHM.

Also it add unpacking of HtmlHelp 2 files (.Hx?).

Also it can used as content plugin, showing info about title of help window, maker of CHM and time of compilation.

Presence of Internet Explorer in system is not necessary.

NB: Plugin can not make full-fledged HtmlHelp files (contents, index, etc.) but it can make CHM-file even if there is one '.htm' or '.html' file in files to be packed. For example, repack this archive to CHM-file. To make full-fledged HtmlHelp use HTML Help Workshop or htm2chm.

If there is not file '#SYSTEM' in root of packed files list it will be created and if there is not some '.hhc' file in packed list, 'stub.hhc' will be created with all files and directories from packing list using <title> of topic. Its order depends on sort type of TC. Default topic will be (what comes first, case insensitive): see 'default_topics' in CHMDir.ini. If there is not such file, first found '.htm' or '.html' in packed list will be used.

For keeping structure of file before repacking it must be unpacked with turned on option 'Show special CHM files' in CHMDir.ini to keep files such as '#SYSTEM' (there is information about title of help window and contents file in this file).

How to install plugin as WCX

Unzip the chmdir.wcx to the Total Commander directory (usually c:\wincmd or c:\totalcmd) or directory as you like
In Total Commander, choose Configuration/Options and open Plugins page
Click Configure in 'Packer plugins (.WCX)'
Type 'chm' as the extension
Click New type, and select the unpacked chmdir.wcx
Click OK
Repeat steps 4-6 for .hxs extension
If its necessary make file CHMDir.ini (or copy from sample.ini) in dir same as plugin

NB: File icons and default action (on <Enter>) will not change. To enter into archive use <Ctrl-PgDn>. If you want to change this to opening archive with <Enter> and showing archive icon:

Choose Configuration/Options... then open page Packer and press button Configure in 'Packer plugins (.WCX)'
In drop-down list 'All file with...' choose 'chm'
In field 'Associate with:' change number NNN before comma to MMM, where MMM=NNN-256

or

Close Total Commander
Open Total Commander's INI-file (usually <windows_dir>\WINCMD.INI) with text editor
In section [PackerPlugins] change NNN in line looks like 'chm=NNN,C:\wincmd\chmdir.wcx' to MMM, where MMM=NNN-256.

To view CHM-file use one of:

command hh <chm-file>,
keystroke <Ctrl-Enter> to insert file name into command line and <Enter> to open file,
right click on file name and choose default action (bolded).

How to install plugin as WDX

Choose Configuration/Options...
Choose page Plugins and in group 'Content plugins (.WDX)' press button Configure.
In the 'Content plugins' dialog box press Add and type '*.wcx' in 'File name' field.
Locate unpacked CHMDir.wcx and press Open.

CHMDir.ini

At startup plugin looks up the file CHMDir.ini in its directory — standard Windows ini-file.

See descriptions in sample.ini.

In order to changes start to work you must restart TC or unload all plugins and change to another archive (TC remember file list of last archive).

Known bugs and limitations

Plugin uses CHMTools that deals with version 3 only.
Plugin uses RAM to hold file names in CHM and for unpacking buffer. So if you have 1000 files in file with 100 bytes average file name length then you need more ~0.5 Mb RAM available.
Plugin will not work with files >= 2 Gb.

CHMView.exe

This program is intended for viewing CHM files without hh.exe. It needs one parameter — CHM file name. It will unpack all files in CHM into temp dir and will try to start default HTML viewer.

wtedit.exe and wtdump.exe

wtdump.exe dumps properties of HtmlHelp window (or default properties in current dir) and sample HHP (HtmlHelp project file) that can be used to create such HtmlHelp.

wtedit.exe allows you to edit HtmlHelp window properties of file that used as program parameter.

Both programs need CHMDir.wcx in its directory or in directory pointed by environment variable 'PATH'.

For more information see HTML Help Web page or Help for HTML Help from HTML Help Workshop.

UnCHMw.exe

This program is stand alone command line version of CHM unpacker.

UnCHMw.exe uses settings from CHMDir.ini.

Added function GetPackerCaps().
