It would be a good idea to have a working XSLT for Boost.Book/tree_control first so we can try out the various ideas. >I'd like to focus on: > > 1.

Disabling section ToC's; 2. Overriding the default ToC mechanism in favour of the tree control menu; 3. Providing "chunks" for the main frame page and the ToC page; 4. Iterating over the various sections and extracting the names of the "chunks" to use as the links; 5. Modifying the way sections are generated if necessary to accommodate the new control; 6. Anything I've forgotten. >I think only time will tell whether it's more annoying to have to >manually [sync] the documentation or to reload the docs when linking >within a page.

Once the code is written it should be possible to play around with what it generates to test the ideas that you and Rene are suggesting.

Gennadiy? Above test actually should pass on almost all compilers (as it does locally). For some reason it fails during regression test. Something about couldn't find pattern file. So, because 1. I do not know how to fix that. 2. Nobody responded on my request 3. This test is not critical for this release 4. We have enough on our plates already I decided to comment it out for now. I plan to reinclude it after release. Gennadiy.

So it appears this idea suffers from the same problems as >Reece's suggestion. The question here is: are we going to place the emphasis on auto-generated docs? If we do this, then it should be possible to do something like: <span onclick = "follow_link(1.5)">Chapter 1.5</span> With regards to the page refreshing, this happens when you select "sync" anyway. Is it possible to use '#' instead of '?', so the browsers won't refresh the docs. This might require a standard naming scheme for <a name = "..."/> marked sections, but this would be easier to do if the docs are auto-generated. For older docs that want to keep their HTML structure but move over to the treeview control, it should be easy to do if: 1. They are compatible with XHTML (i.e. they can be loaded in an XML client and manipulated via an XSLT stylesheet, e.g. using xsltproc). NOTE: This should be trivial if the HTML has been run through htmltidy. 2. The section format follows a regular pattern, e.g. h1 elements for level 1, h2 for level 2, etc. This would allow you to: 1. Insert and generate the treeview control by making a pass over the hN tags. 2. Clean up sections of the form: <a name = "..."/><hN>...</hN> Issues would be: 1. Do we remove the ToC provided in the HTML doc (can we detect and remove/use it?) 2. Have we detected the document structure correctly? 3. Other issues I've missed.

In particular, losing features that one learns to take for granted on some platforms (like thread stop, suspended start) is not motivating. Also, relying on OS notifications (like DLL_THREAD_DETACH on Win32) for TLS cleanup, and extra code required to support boost threads static library on Win32 is not my favourite, despite a rather ingenious implementation. I think it would be best if we can completely avoid using Win32 DLL process/thread notifications and make TLS cleanup part of the thread function object. I already expressed, somewhat radical I guess, opinion that, at least on Win32, TLS functionality is probably not worth the trouble of existing cleanup support code.

Threads Rewrite?
by David Abrahams 31 Jul '04

31 Jul '04

Hi Boosters, I've tried several times to contact Bill Kempf about moving forward with threads, even leaving him messages on his home answering machine. I've had no reply. It's important that we make an effort to move Boost towards a uniform licensing scheme, and the threads library is an especially important one to do that for. We've been talking about significant restructuring in this library; is it likely that we'll get to a point where the original code can be thrown out? That may be the only way we'll be able to change the license. IMO the docs really *need* to be thrown out and re-done, even if the design were to stay substantially the same. Thoughts? -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

Ok, thanks. I downloaded it and I am using it for testing now. AFAICT, there's no problem with Spirit code and the errors above (which is ok on all compilers, including Comeau) seem to be VC8.0 bugs. For that matter, wouldn't it make sense for VC8.0 in the test reports be named as VC8.0 Beta to avoid confusion? << Now I notice more and more compilers added in the reports. Cool! Yet... arghhh!

Range/workaround test: SFINAE defect on EDG?
by Stefan Slapeta 31 Jul '04

31 Jul '04

First of all, the most important question: Why do we test workarounds for partial spezialization on compiler which don't need these workarounds? I've isolated the problem with the failing range/workaround testcase on Intel 8. IMO it's a compiler defect because the function template in is_array should be disabled by SFINAE. This code fails to compile with the current comeau release, too. template <class T> struct wrap {}; // this one should disabled because it's not allowed to return an array: template< typename T > T(* is_array_tester1(wrap<T>) )(wrap<T>); char is_array_tester1(...); void f() { sizeof(is_array_tester1(wrap<int[42]>()); } Shall a submit a DR?

Please could anybody explain me what the reason for white cells in the regression tests is and why these tests are not executed? Concrete examples are: - test: ifstream_line_iterator_test - numeric/ublas: test7 Thanks, Stefan

Javascript Tree Control [was: Serialization Menu]
by Jonathan Turkanis 31 Jul '04

31 Jul '04

Dear All, There was a discussion a couple weeks ago about the javascript menu in Robert Ramey's serialization docs. I suggested making a menu component available Boost-wide and testing it on a large number of browsers to address portability issues. I've written a preliminary version, documented here: http://tinyurl.com/6a9ym and downloadable from here (its a bit large because it contains a bunch of screenshots): http://tinyurl.com/6w56v (tree_control.zip) You can see the control in action here: http://tinyurl.com/6tdvy I've verified that it works -- with varying levels of functionality -- on 26 browsersincluding some antiques such as IE3.02.
