debugging mtxrun

Hi Mojca, hi everyone, can someone please help me getting mtxrun work properly on Debian again??? Ok, I have current luatex, and current context from TL2012 packaged for Debian. In Debian we have a bit a funny layout: /usr/share/texlive/texmf-dist /usr/share/texlive/texmf /usr/share/texmf /etc/texmf I have edited texmfcnf.lua which is located in /usr/share/texmf/web2c to look like (only relevant parts extracted): ... local texmflocal = "/usr/local/share/texmf"; .. TEXMFSYSVAR = "/var/lib/texmf", TEXMFVAR = "home:.texmf-var", ... TEXMFCACHE = "$TEXMFSYSVAR;$TEXMFVAR", TEXMFCONFIG = "home:texmf-config", ... TEXMFMAIN = "/usr/share/texlive/texmf", TEXMFDIST = "/usr/share/texlive/texmf-dist", TEXMFCONTEXT = "/usr/share/texmf", TEXMFLOCAL = /usr/local/share/texmf", TEXMFSYSCONFIG = "/etc/texmf", .... TEXMF = "{$TEXMFCONFIG,$TEXMFVAR,$TEXMFHOME,$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFLOCAL,!!$TEXMFCONTEXT,!!$TEXMFMAIN,!!$TEXMFDIST}", (the TEMXCONFI is actually a bug and should be .texmf-config) But, mtxrun does not find anything.... # mtxrun --generate --verbose resolvers | resolving | creating instance resolvers | resolving | variable 'SELFAUTOLOC' set to '/usr/bin' resolvers | resolving | variable 'SELFAUTODIR' set to '/usr' resolvers | resolving | variable 'SELFAUTOPARENT' set to '.' resolvers | resolving | variable 'TEXMFCNF' set to '' resolvers | resolving | variable 'TEXMF' set to '' resolvers | resolving | variable 'TEXOS' set to '/usr' resolvers | resolving | resolvers | resolving | using configuration specification 'home:texmf/web2c;selfautoparent:texmf{-local,-context,}/web2c' resolvers | resolving | resolvers | resolving | unknown configuration file '/root/texmf/web2c/texmfcnf.lua' resolvers | resolving | unknown configuration file './texmf-local/web2c/texmfcnf.lua' resolvers | resolving | unknown configuration file './texmf-context/web2c/texmfcnf.lua' resolvers | resolving | unknown configuration file './texmf/web2c/texmfcnf.lua' resolvers | resolving | resolvers | resolving | warning: no lua configuration files found resolvers | resolving | no texmf paths are defined (using TEXMF) resolvers | resolving | mtxrun | mtxrun | runtime: 0.008 seconds # which is unlucky .... I guess I have to *edit* mtxrun to make it find the texmf.cnf files? But I have no idea what I have to do. In addition, when I do: # TEXMFCNF="/usr/share/texmf/web2c/;/etc/texmf/web2c" mtxrun --generate --verbose it find the proper texmfcnf.lua, but seems to not be interested in reading the right values from it: # TEXMFCNF="/usr/share/texmf/web2c/;/etc/texmf/web2c" mtxrun --generate --verbose resolvers | resolving | creating instance resolvers | resolving | variable 'SELFAUTOLOC' set to '/usr/bin' resolvers | resolving | variable 'SELFAUTODIR' set to '/usr' resolvers | resolving | variable 'SELFAUTOPARENT' set to '.' resolvers | resolving | variable 'TEXMFCNF' set to '/usr/share/texmf/web2c/;/etc/texmf/web2c' resolvers | resolving | variable 'TEXMF' set to '' resolvers | resolving | variable 'TEXOS' set to '/usr' resolvers | resolving | resolvers | resolving | using configuration specification '/usr/share/texmf/web2c/;/etc/texmf/web2c' resolvers | resolving | resolvers | resolving | found configuration file '/usr/share/texmf/web2c/texmfcnf.lua' resolvers | resolving | unknown configuration file '/etc/texmf/web2c/texmfcnf.lua' resolvers | resolving | resolvers | resolving | skipping configuration file '/usr/share/texmf/web2c/texmfcnf.lua' (no file) resolvers | resolving | no texmf paths are defined (using TEXMF) resolvers | resolving | mtxrun | mtxrun | runtime: 0.007 seconds # Any help appreciated... otherwise we continue shipping 2011 context in a broken state in Debian :-( or worse, I have to call for removal before freeze.

\startframed and parameters
by Wolfgang Schuster 17 May '12

17 May '12

Hi Hans, \startframed doesn’t accept local settings because \pack_framed_process expects two arguments. Here is only one optional argument \unexpanded\def\startframed {\dosingleempty\pack_framed_start_framed} \def\pack_framed_start_framed[#1]% {\bgroup \advance\framednesting\plusone \expandafter\let\csname\??ol:\the\framednesting\s!parent\endcsname\??ol \pack_framed_process[\??ol:\the\framednesting][#1]% \bgroup} while \framed accepts two \unexpanded\def\framed {\bgroup \advance\framednesting\plusone \expandafter\let\csname\??ol:\the\framednesting\s!parent\endcsname\??ol \dodoubleempty\pack_framed_process[\??ol:\the\framednesting]} and \pack_framed_process checks for the second argument: \unexpanded\def\pack_framed_process[#1][#2]% assumes a \dodoubleempty (slows down), also should have leading \bgroup {\bgroup \pack_framed_initialize{#1}% \ifsecondargument % faster \getparameters[\currentframed][#2]% here ! \fi \pack_framed_process_indeed} Test file: \starttext \secondargumentfalse % was true from a previous command but should be false \startframed[frame=off]text\stopframed \framed[frame=off]{text} \stoptext Wolfgang

It depends on how much support you want. - for basic language support we need an entry in lang-def.mkiv - for labels we need entries in lang-txt.lua - for patterns you need to check with Mojca what file we need to use - if you also want commanda and keywords in esperanto we need to extend mult-def.lua Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Wrong structure numbers in margin
by Marco 16 May '12

16 May '12

Hi Hans, could you check the definition of \placeheadmarginalternative in strc-ren.mkiv? The current solution fails when structure number are set to “margin” in a doublesided layout because of the hard-coded \leftmargindistance. The “maybe better” solution actually seems to work better. \setuplayout [backspace=8cm, width=5cm, leftmargindistance=2cm] \setuppagenumbering [alternative=doublesided] \setupheads [alternative=margin] \unexpanded\def\placeheadmarginalternative#1#2% {\vbox {\localheadsetup \begstrut % use one \strut here! \dontleavehmode % in case there is no strut, else side effects with llap \ifconditional\headshownumber % this gives a wrong result on the second page %\llap{\hbox{\hfill{#1}\hskip\localheadskip\hskip\leftmargindistance}}% introduces whitespace % maybe better: \inleftmargin{\hbox{\hss{#1}\hskip\localheadskip}}% \fi {#2}}} \showframe \starttext \chapter{Chapter} \null\page \section{Section} \subsection{Subsection} \subsubsection{Subsubsection} \stoptext Regards Marco Patzer

Streams: compensation not happening correctly.
by Sietse Brouwer 12 May '12

12 May '12

Hi all, I was trying to work out the streams mechanism, and found the following bug (I call my streams [left] and [right]): * An unwanted extra compensating line is inserted after the first block of the [left] stream that is as tall as, or shorter than, its corresponding block in the [right] stream. * If that extra line has not yet been inserted, then when two blocks have the same height the one on the [left] is wrongly measured as being shorter. (For a single line containing a capital A, it's 561512 vs 932551.) * This happens only once: subsequent identical-content blocks will indeed have identical heights. This is just a bug report; for me, at least, a fix is not required. Minimal example and relevant bit from its output log below. Cheers, Sietse Sietse Brouwer ---- minimal example ---- \enabletrackers[streams.flushing] \setuplayout[grid=yes] \showgrid \starttext \enableoutputstream[left] A %\input ward \par \pushoutputstream % Unwanted compensating line inserted here B \par \pushoutputstream % If the Ward paragraph is enabled, the extra line is inserted here, instead.
