.chm (Compiled HTML) Support
44.39 KB, application/octet-stream
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8+) Gecko/20020202 BuildID: I want very much the mozilla to support micro$oft's .chm format (that stands for compiled HTML) Reproducible: Always Steps to Reproduce: 1. Try to open any chm file 2. you'll get nothing :) 3. Actual Results: no support Expected Results: Support
What this should be: Summary => "[RFE] .chm (Compiled HTML) Support" I'm not sure if we really should implement this.
Summary: This is not a bug but required feature → [RFE] .chm (Compiled HTML) Support
Since .chm is a Microsoft proprietary data format, I see no reason for Mozilla supporting it.
Artem, is there a clear specification available that explains the .chm format?
I know this is filed, but I can't find it :-(. chm is bascically a cab, which is like a zip.

dougt: to support chm we will need the same sort of code as for jar. which afaik lives in necko. Otoh, the reason i sent it to Netwerk was because i hoped the QA could dupe it for me.

See here if you need any documents about .chm: http://directory.google.com/Top/Computers/Data_Formats/Help/HTMLHelp/ http://msdn.microsoft.com/library/default.asp?url=/library/en-us/htmlhelp/html/vsconHH1Start.asp
Those documents all nicely describe how one generates chm files using various (mostly microsoft) tools. The documents say nothing about: 1) Reading a chm file in anything but the help viewer 2) The actual format of the chm files So as things stand the way to support chm would be to reverse-engineer the format by trial and error...
No dupes found. Confirming enhancement request.
Status: UNCONFIRMED → NEW
Ever confirmed: true
This Bug is Platform All, OS All; does that mean the request is to implement .chm Support on all platforms? Like we did with Windows BMP and ICO (I think)?
.chm support is worth implementing at least on non Windows platforms
This would mean that I could create a set of documents or a book, pack it into a .chm and give it to somebody(?). Also, I guess it would be possible to pack multiple HTML pages on a website into a single .chm file.
A parital description of the format is available at wotsit: http://www.wotsit.org/ http://www.wotsit.org/download.asp?f=chm
HomePage of the CHMLib is http://126.96.36.199/~jedwin/projects/chmlib/
Comment on attachment 129274 [details] This is an LGPL library which provides a full support for CHM Just a reminder, you can't commit LGPL code into mozilla. Code must be trilicensed.

A dissassembly of .CHM format can be found here: http://www.speakeasy.org/~russotto/chm/chmformat.html One can easily create a parser of .CHM using this draft ;)
This is an e-mail response I've got from CHMlib developer. He agree to relicense his library to whatever license you need. Please, give me a point what to ask him if this bug is still relevant.

Please, visit >> https://bugzilla.mozilla.org/show_bug.cgi?id=123320 for details. I'm not opposed to "trilicensing" chmlib, I think, though I don't exactly know what this means. It's got to be made available under three different licenses? Or... Can you point me at some information on what trilicensing means in this context? - jed
http://www.mozilla.org/MPL/relicensing-faq.html#new-license explains how the trilicense stuff works. Past that, firstname.lastname@example.org would need to be talked to about adding another library into the mozilla tree, I guess. And then someone would have to actually do the work of making this library interact with Gecko in the right way.

I own a software company which creates .html files with links to a chm file. An example of such a link is: <A HREF = "mk:@MSITStore:C:\Program Files\RUG Tools\RUG-III Analyzer 1.31\Includes\MDS20Item.chm::/g1aactivitiesofdailylivingadlselfperformance7daylookback1.htm" target="_blank">G1aA</A> I got this URL by using Micorosoft's HTML Help viewer program, right clicking on links, and seeing the properties. Internet Explorer handles this fine, but Mozilla Firefox gives me the error message: Firefox doesn't know how to open this address, because the protocol (mk) isn't associated with any program. I am a novice user of Firefox, and I realize this bulletin board is for developers. But if you could tell me how I can get Firefox to associate a program with this protocol, and which program to use, or any other workaround for my clients, please let me know. Thanks.
