Hello Fabrice


Thanks for your follow up. I saw your picture and I am choked to see that TeXmacs looks completely awful. I include a picture of my TeXmacs installation, running the first screen. It looks good, but lacks the images of the pair of bulls either the spanish or the english version (from Help -- About -- Welcome original message). You can see it in the following web address:

https://docs.google.com/document/d/1-27EfiEabvk08jXNGhd3Fy9UjIla5G8npDg_cHJFEnk/edit?hl=es

I am using TeXmacs 1.0.7.10 on Windows XP SP3 Spanish, with spanish locale.

TeXmacs ran well, except that the only fonts that works are Roman, Concrete and Deja Vu (I have this last font installed in windows/fonts directory and also in MikTeX directory). Therefore the situation is at least aceptable with respect to a minimum variety on fonts selection.

Neither works the invocation of Asymptote, Maxima, Gnuplot or Graphviz, which I have installed in my sistem. The last year I read somewhere that for windows, those sesion scripts doesn't work. I ignore why and if the situation is remediable by an user.

I searched the readme text files in TeXmacs installation for hints about the fonts use and found the following reference:

----
GNU TeXmacs uses the following algorithm to find fonts:

- Look whether the font is in one of directories specified by the user paths TEX_TFM_PATH or TEX_PK_PATH.
- Look whether the font is installed by default in $TEXMACS_PATH/data/tfm or $TEXMACS_PATH/data/pk.
- Look whether the font was already generated in the TeTeX distribution (using kpsepath).
- Automatically generate the font using MakeTeXTFM and/or MakeTeXPK.
-----

And from 'compiling TeXmacs' I learned that:

----
From compiling TeXmacs:

* You have problems with the font system from TeX when running.
Solution: get a version of TeX with 'kpsepath', 'MakeTeXPK' and 'MakeTeXTFM'.

* TeXmacs runs fine, but certain fonts are not displayed correctly.
Solution: This problem may have several causes:
o You use a recent version (>= 7.3) of RedHat Linux or one of its clones. On such systems, the installation of
TeTeX is bugged and you need to change some permissions in order to allow font generation by Metafont.
As root, type chmod -R a+rw /var/lib/texmf/*
o You do not use a standard TeX/LaTeX distribution, such as TeTeX (standard distributions come with scripts
for generating fonts, such as 'mktextfm' or 'MakeTeXTFM'). You may either install a more standard TeX/LaTeX
distribution, or download some pregenerated fonts from texmacs.org.
----


So, I made the two environmental variables (TEX_TFM_PATH and TEX_PK_PATH). Also, modified by hand the file settings.scm in "C:\Documents and Settings\Denis\Datos de programa\TeXmacs\system", adding the following content:

----
(VERSION "1.0.7.10")
(KPSEPATH "false")
(KPSEWHICH "C:\Archivos de programa\MiKTeX 2.9\miktex\bin\kpsewhich.exe")
(MAKETFM "C:\Archivos de programa\MiKTeX 2.9\miktex\bin\miktex-maketfm.exe")
(MAKEPK "C:\Archivos de programa\MiKTeX 2.9\miktex\bin\miktex-makepk.exe")
(TEXHASH "C:\Archivos de programa\MiKTeX 2.9\miktex\bin\texhash.exe")
(TFM "C:\Archivos de programa\MiKTeX 2.9\fonts\tfm")
(PK "C:\Documents and Settings\Denis\Configuración local\Datos de programa\MiKTeX\2.9\fonts\pk")
(PFB "C:\Archivos de programa\MiKTeX 2.9\fonts\type1")
(DPI "600")
(EC "true")
----

Originally the file contained the value "false" or "{}"for almost all the variables and '(EC "false")'.

Since I suspected that TeXmacs wasn't able to find my MiKTeX installation. I searched for kpsewhich, maketfm, makepk and texhash. Maketfm and makepk are named differently and this could be an issue with TeXmacs.

As a result, TeXmacs made a clear effort to build the fonts, but for some unknown reason the process failed. I suspect that this is related to the lack of kpsepath in MikTeX.

After this, I was determined to found and install TeTeX, but is an abandoned version without an addres to download it from for windows. LaTeX live, informs that can't be two LaTeX version installed because the environmental variables conflict each other.

After this failure, I searched for a LaTeX package to print font characters tables, but the size of the effort is big and also, the font name in LaTeX, although documented with the Karl Berry naming scheme, is really hard to use to construct the LaTeX instructions to build fonts tables. Since I have a full MiKTeX instalation, I made a directory listing, and found that I have 512 font files. For the mean time I haven't been able to find a programatic way to declare every font and instruct pdfLaTeX to generate the font table, which was my hope to produce the font metrics files that TeXmacs uses.

I also have the idea that the font encoding tables that TeXmacs uses to access the characters with diacritical marks, those of Latin 1 in TeX encoding or ISO-8829-1, perhaps have some problem, but I haven't inspected in educated manner those tables because I still don't know how this encodings works.

What I have found so far is that the mechanism for building fonts, fails in Windows XP SP3. I don't now if this situation is specific to XP or to Windows. I even installed TeXmacs in a path without spaces, without solving the fonts problem. But the hints indicates me that is related to an inability to locate and use MiKTex.

The solution of installing prebuild fonts, does not work well also for me. There are two files available. One of them is in TeXmacs web site. The other one which I did not retained the web address where I found it, I believe is residing in git hub. This is more complete, but comes from a Linux box and uses 'make' to build and install and wasn't able to use it effectively.

I installed the font package from TeXmacs web site. The first time in my user directory and the second time in the program directory, without a positive result. The failure of using precompiled fonts with TeXmacs indicates me, that the problem to displaying correctly the fonts, resides in TeXmacs itself.

I have detected two problems:

- TeXmacs does not found the declared font and uses the Roman face instead (declared using the menu selecting
'Document -- Font -- Text font).
- TeXmacs does not display correctly characters with diacritical marks common in spanish
(á é í ó ú ü Á É Í O Ú ñ Ñ ¿ ¡) with fonts different from the three I mentioned previously.


As you might see, I am still far away to found a solution, but I have hope that I will find one.

If you like, both of us can make comparisons of our Windows XP installations. Perhaps your machine lacks some software, environment variables or a correct key in the windows registry.


Thanks for your interest,


Denis J Navas

Hello Denis,

How do your fonts look like ?
I juste upgraded Texmacs from 1.0.7.9 to 1.0.7.10 and the welcome
message looks like this:
http://imageshack.us/photo/my-images/7/texmacs.jpg

There is nothing new, the previous version had the same problem.
And the behaviour is the same problem on two different computers (both
are under windows XP). I have no problem with Texmacs under Linux, but
this bug prevents me from using Texmacs from Windows.

Cheers,
fabrice
