https://bugzilla.novell.com/show_bug.cgi?id=833247 https://bugzilla.novell.com/show_bug.cgi?id=833247#c2 Lawrence Somerville changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |l_pat_s@hotmail.com --- Comment #2 from Lawrence Somerville 2013-08-21 00:35:50 UTC --- August 20, 2013 After a few weeks of time, gratefully I found what I will call a "workaround" solution for this problem using a clue kindly provided by Bob Tennent. On http://www.tug.org/pipermail/tex-live/2011-November/030599.html on the Internet he wrote, "...in some Linux distributions the latex2html package will *depend* on a full installation of something hopelessly out-of-date like texlive-2007 or tetex which complicates the installation" (of I think LaTeX2HTML). And at http://www.tug.org/pipermail/tex-live/2011-November/030604.html, continuing in the same "chain" of likely electronic-mail letters, Bob Tennent further wrote, "Installation of latex2html-2008 from the tarball at CTAN" (the Comprehensive TeX Archive Network on the Internet) "does avoid the dependency issues and it's likely to need updating." These writings of Bob Tennent gratefully gave me the clue that LaTeX2HTML 1.71, which worked probably well for me with portions of TeX Live 2011, might be noncommensurate in some way with portions of TeX Live 2012. So in attempting the solution of Bob Tennent I obtained the file latex2html-2012.tgz from a CTAN Web page. Within openSUSE-12.3's Yet another Software Tool 2's (YaST2's) Software Management I deleted the installations of the openSUSE-12.3 software packages entitled "latex2html," "latex2html-doc," and "latex-pngicons." I unpacked the downloaded file latex2html-2012.tgz using the command "tar xvzf latex2html-2012.tgz" in a new folder and followed the instructions in a file entitled "INSTALL," which came within that .tgz file to install what turned out to be LaTeX2HTML 2012 (1.2) in my installation of portions of TeX Live 2012 in an openSUSE-12.3, Linux operating system. The essential commands in doing so were "./configure --prefix=/usr", "make," and "make install". The result was the installation of some executable LaTeX2HTML files in the directory /usr/bin, some shared library files in the directory /usr/shared/lib/latex2html, and some unshared library files in the directory /usr/lib/latex2html, with each of those three directories beginning with the input "prefix" of "/url". After deleting old copies of everything associated with my test file Throwaway29.tex, except the file Throwaway29.tex itself, gratefully the result of executing "latex Throwaway29.tex" twice and "latex2html -debug -nonavigation -no_math -html_version 3.2,math -split 0 Throwaway29.tex" once was that the equivalent of the expression y=(1/2) x^2 without the parentheses and with a horizontal fraction line was properly displayed in the output file ..../Throwaway29/Throwaway29.html when viewed in the Web browser Konqueror (Some problems in displaying other mathematics after similarly processing a different .tex file were rectified by making the minor changes discussed in Appendix II.). Afterwards the new folder into which the file latex2html-2012.tgz, which had been downloaded from a CTAN Web page, had been unpacked could be deleted from my computer's hard-disk drive. The above success shows that LaTeX2HTML 2012 (1.2) can be made to work with portions of TeX Live 2012 in an openSUSE-12.3, Linux operating system (As of August 14, 2013, TeX Live 2013 was not yet available for installation from the standard openSUSE-12.3 repositories for stable openSUSE 12.3. But from Harvey's posting at http://bbs.archlinux.org/viewtopic.php?pid=1299370 on the Internet, there is a possible clue that TeX Live 2013 may have worked with LaTeX2HTML 2008-2, dated July 10, 2013, up to, but not including, the TeX Live 2013 update named texlive-core2013.30962-1. Based on Harvey's joke near the end of his posting there and because that Web page has "linux" in its Uniform Resource Locator [URL], I suppose that Harvey may have been using some distribution of a Linux operating system in the results he reported. He also wrote that he reported his problem with LaTeX2HTML 2008-2 and TeX Live 2013, a problem different from my problem with LaTeX-coded fractions like \frac{1}{2}, as a "bug." I am not certain whether he reported that software "bug" to the developers of TeX Live or to the developers of the distribution of the Linux operating system that he was using at the time he found what he speculated might be a "bug."). Without delving deeply into the computer codes involved, I have two general hypotheses to explain this success: 1) Similar to what Bob Tennent reported for probably an earlier version of LaTeX2HTML and some distribution or distributions of a Linux operating system that is or are unknown to me, perhaps in my case as well there was in some way some kind of a mismatch between LaTeX2HTML 2008 (1.71) and portions of TeX Live 2012 in my installation of the openSUSE-12.3, Linux operating system. 2) In openSUSE 12.3, compared to openSUSE 12.2, I think some changes were made in grouping some software packages together. So perhaps there was a problem on the openSUSE-12.3 side of things that prevented LaTeX2HTML 1.71 from working well with portions of TeX Live 2012. I see short-, intermediate-, and long-term solutions to the general problem of getting LaTeX2HTML to work well with portions of TeX Live in a Linux operating system. The short-term solution is the one I explained in the paragraph two paragraphs above this one that gratefully worked for me in an openSUSE-12.3, Linux operating system and that one could hope might also work in other distributions of the Linux operating system. The intermediate-term solution is for you to fix the problem for users of the version of LaTeX2HTML that is supplied to openSUSE-12.3 users from openSUSE-12.3's software repositories.---If the above hypothesis 1 is correct without any complications from hypothesis 2, the intermediate-term solution might be as simple as openSUSE-12.3 developers changing the version of LaTeX2HTML they supply from their online repositories from the year-2008 to the year-2012 version of it that is available from the CTAN. You could try doing that first. If that does not succeed in eliminating the improper rendering of the LaTeX code \frac{1}{2}, then next try to find a possible problem in how openSUSE 12.3 has LaTeX2HTML 2012 (1.2) and TeX Live 2012 configured to work with each other. But the long-term and more general solution for all distributions of the Linux and Windows operating systems which may make use of TeX Live could be to incorporate a recent version of LaTeX2HTML in a recent version of TeX Live and from testing LaTeX2HTML and LaTeX in TeX Live with .tex files containing some mathematical expressions before distributing Tex Live to in that way ensure that LaTeX2HTML within TeX Live will work well with TeX Live. I have written to an electronic-mail address for TeX Live recommending that TeX Live in the future include LaTeX2HTML. Appendix I: Licensing of LaTeX2HTML 2012 (1.2) For LaTeX2HTML 2012 (1.2) I found license information in the file /usr/share/lib/latex2html/docs/licence.tex in my installation of LaTeX2HTML obtained from the CTAN: "Use and copying of this software and the preparation of derivative works based on this software are permitted, so long as the following conditions are met: \begin{itemize} \item The copyright notice and this entire notice are included intact and prominently carried on all copies and supporting documentation. \item No fees or compensation are charged for use, copies, or access to this software.

The aggregation of another unrelated program with this software or its derivative on a volume of storage or distribution medium does not bring the other program under the scope of these terms. \end{itemize}" Appendix II: Changes That Were Necessary to Make in LaTeX2HTML 2012 Files to Avoid Some Problems With Images of Some Mathematics Appearing in a HyperText Markup Language File Produced by the Combination of Programs LaTeX and LaTeX2HTML 2012 (1.2) The changes to LaTeX2HTML discussed here have kindly been previously discussed by Shigeharu Takeno. For example, he discussed the changes to the Perl script file latex2html at http://tug.org/mailman/htdig/latex2html/2004-February/002688.html on the Internet. In the file /usr/bin/latex2html I added a ? after each # in lines 16,454-16,455 as follows: $math_verbatim_rx ="verbatim_mark#?math(\\d+)#"; $mathend_verbatim_rx ="verbatim_mark#?mathend([^#]*)#"; I did not find the file latex2html.pm in LaTeX2HTML 2012 (1.2) and therefore did not make similar modificiations within it. I left the following line in the file /usr/share/lib/latex2html/versions/math.pl unchanged: $mathend_mark = "\n${verbatim_mark}mathend000#"; because $mathend_mark is used several times in that file math.pl. I found that commenting out by prepending that line of code with a # was not essential for the successful rendering of mathematical symbols by LaTeX2HTML. And furthermore commenting out that line of code could conceivably result in $mathend_mark being undefined, if the lines using $mathend_mark in that file math.pl are ever reached and if $mathend_mark is not effectively defined for the file math.pl elsewhere within the LaTeX2HTML code. And in the file /usr/lib/latex2html/l2hconf.pm I prepended line 136 with a # as follows: # $DVIPSOPT= ' -Ppdf -E'; The line 169 of the same file was already prepended with a # as follows: # $DVIPSOPT .= " -Ppdf"; I left line 151 of the same file unchanged as follows: $DVIPSOPT .= " -E"; . -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=833247 https://bugzilla.novell.com/show_bug.cgi?id=833247#c6 --- Comment #6 from Lawrence Somerville 2013-10-08 19:20:26 UTC --- Again from my above comment 2, '...the intermediate-term solution might be as simple as openSUSE-12.3 developers changing the version of LaTeX2HTML they supply from their online repositories from the year-2008 to the year-2012 version of it that is available from the CTAN' (Comprehensive TeX Archive Network). The openSUSE-12.3 developers would probably have to make some change or changes from the .tgz file provided by the CTAN to the proper kind of file or package with which Yet another Software Tool 2 (YaST2) is "used" to providing to end users of such software. Once installed, someone could try to run the computer codes LaTeX and LaTeX2HTML on a simple .tex file containing the LaTeX code \frac{1}{2} to see if the fraction 1/2 containing a horizontal instead of a diagonal fraction line appears in the .html (HyperText Markup Language) output file produced by LaTeX2HTML or not. The developers of openSUSE-12.3 Linux could try this approach first. On October 8, 2013 I could still click on the hyperlink reading latex2html-2012.tgz on the Web page with the Uniform Resource Locator (URL) http://www.ctan.org/tex-archive/support/latex2html and see that a download of the file latex2html-2012.tgz could be provided. Note that this approach is to move to a more recent version of LaTeX2HTML than the year-2008 version of it, namely the year-2012 version of LaTeX2HTML, rather than to go back to portions of TeX Live 2011, which I found did work with the year-2008 version of LaTeX2HTML. An openSUSE-12.3 repository was providing at least portions of TeX Live 2012 in probably August of the year 2013. If this suggestion of an openSUSE-12.3 repository providing in the proper form the year-2012 instead of the year-2008 version of LaTeX2HTML does not work to eliminate the improper rendering by LaTeX2HTML of the LaTeX code \frac{1}{2}, then again from my comment 2 here, openSUSE-12.3 developers could "next try to find a possible problem in how openSUSE 12.3 has LaTeX2HTML 2012 (1.2) and TeX Live 2012 configured to work with each other." For example, there should be a good match between the directories where TeX Live 2012 files are located and where LaTeX2HTML 2012 "expects" the TeX Live 2012 files that it needs are located and/or possibly vice versa. If such mismatching of directories is a problem, then either the LaTeX2HTML code or the TeX Live 2012 code might need to be modified to enable such directory matching between TeX Live 2012 and LaTeX2HTML 2012. But, thanks to Bob Tennent's postings at http://www.tug.org/pipermail/tex-live/2011-November/030599.html and http://www.tug.org/pipermail/tex-live/2011-November/030604.html on the Internet, with the file latex2html-2012.tgz obtained from the CTAN and the gratefully successful at least partially manual installation procedure I discussed in my comment 2 here, such directory mismatches are apparently avoided. The intermediate-term solution I request here to instead while online have YaST2 install LaTeX2HTML 2012, if that works well I think would be better than having to partially manually install LaTeX2HTML 2012 obtained from the CTAN. I am not aware of any recent result for what I consider to be the ultimate, future, long-term solution for LaTeX2HTML-TeX Live compatibility that I suggested in my comment 2 here. That would be to have a version of LaTeX2HTML that is compatible with TeX Live included as a part of TeX Live, for example possibly in an updated TeX Live 2013 or in future versions of TeX Live. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As I hope I mentioned, I gratefully have LaTeX2HTML labeled with the year 2012 obtained from the Comprehensive TeX Archive Network (CTAN) working in openSUSE-13.1 after having installed it in the manner I discussed earlier in this thread. I would prefer not to uninstall this working setup of LaTeX2HTML just to test the version of LaTeX2HTML now available from openSUSE-13.1 repositories in openSUSE 13.1. So I leave a LaTeX-coded fraction like \frac{1}{2} for someone else to test with LaTeX and LaTeX2HTML supplied from openSUSE-13.1 repositories. Had I not already installed LaTeX2HTML from the CTAN your suggestion would be worth trying. Thanks for any effort you or others kindly made in fixing or trying to fix the problem I discuss here. I hope you can understand my thinking. Please arrange for any fix you or others made of this problem to be propagated into future versions of openSUSE. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=833247 https://bugzilla.novell.com/show_bug.cgi?id=833247#c18 --- Comment #18 from Lawrence Somerville 2014-02-25 00:49:19 UTC --- Hello, Petr Gajdos. As it turns out to deal with other problems I formatted the openSUSE-containing partition of my virtual “hard-disk drive” and reloaded the 64-bit, openSUSE-13.1, Linux operating system twice for use as the virtual “machine” of Oracle Virtual Machine (VM) VirtualBox 4.3.6 r91406. So this has made a good opportunity for me to test the fix of the LaTeX2HTML problem with LaTeX code of the form \frac{1}{2} that you or other people have kindly made in the latex2html software package provided by openSUSE 13.1. First I noticed that the version 2008-26.4.1 of the software package latex2html provided via an openSUSE-13.1 Web page matches the version of the source code for latex2html that someone provided me in this posting “thread” that likely contains the fix to my posted problem; secondly I noticed that the latest “build” date was January 10, 2014, long after Petr Gajdos's November 26, 2013 notification of the fix, So that's good! It meant that there was a chance that the January 10, 2014 “build” could include the fix. So I tried that openSUSE-13.1-provided version 2008-26.4.1 of latex2html after performing the editing in my “Comment 2” in this “thread.” And gratefully I confirm that the problem in LaTeX2HTML rendering LaTeX code of the form \frac{1}{2} has been fixed in the software package latex2html 2008-26.4.1 provided by an openSUSE-13.1 repository for my installation of the 64-bit, openSUSE-13.1, Linux operating system! Thank you or whoever made that fix! In Yet another Setup Tool 2's (YaST2's) Software Management I searched for “latex2html” and then after it was found in that search clicked on that name. Next in the lower pane of Software Management I clicked on “Dependencies” and saw that texlive-dvips was listed for “Installed Version” and “Available Version” “Provides:”. So based on Petr Gajdos's report that texlive-dvips was missing from the dependencies of of the latex2html package, that omission appears to have been fixed. I have a minor correction to my posting in “Comment 2” of this “thread.” There I have the phrase “I added a ? after each # in lines 16,454-16,455 as follows:”. However, each of those lines contains two #s. So here is the corrected phrase: “I added a ? after the first # in each of the lines 16,454-16,455 as follows:”. Sorry, I made that error. The line numbers for the corresponding lines of code are slightly higher in the more recent “build” and/or version 2008-26.4.1 of the software package latex2html than the line numbers given above. In addition, I suggest that the edits I mentioned in "Comment 2" be checked and, if necessary to be made, be made in the version of the software package latex2html that openSUSE makes available via its repositories. Thanks for your kindly provided help already! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
