\placetable vs. \placefloat and option "none"
by Lukas/ConTeXt 07 Jul '20

07 Jul '20

Hello, option "none" has different effect with \placetable and \placefloat. No problem with this, but as I thought both commands raise from the same code (or more precisely: I thought that \placetable is special case (specialization) of \placefloat), I'm a bit surprised that \placefloat[none] keeps caption whilst \placetable[none] supresses it. See the sample: ---- \setupexternalfigures[location=default] \starttext \placetable[force,none]{}{\externalfigure[cow]} % [1] \placefloat[force,none]{}{\externalfigure[cow]} \stoptext ---- (I'm aware that I'm placing \externalfigure into \placetable in [1] - does it matter?) - Also relates here: https://wiki.contextgarden.net/Command/placefloat . Best regards, Lukas

Bad interaction between \setupinteraction and \defineenumeration
by Jairo A. del Rio 07 Jul '20

07 Jul '20

The following: \setupinteraction[state=start,focus=standard,color=black,contrastcolor=black] \defineenumeration[proposition][alternative=top,text=Proposición,headalign=middle,numberconversion=R,headstyle=\WORDS,style=\emph,referenceprefix=prop] \starttext \startproposition[1] \dorecurse{10}{\input ward} \stopproposition \in[prop:1] \stoptext works almost perfectly. However, the cross-reference does not work, even if the number of the enumeration is displayed correctly. The example fails both in LuaTeX and LuaMetaTeX. As I remember, the problem appeared as early as 2019, so not a matter of a bad installation. Any ideas? Cordially, Jairo :)

Resetting image width
by Henning Hraban Ramm 06 Jul '20

06 Jul '20

Hi, for collecting a lot of images into a booklet I set \setupexternalfigures[width=\textwidth,maxheight=\textheight] but would like to have some single images defined by height and proportional width, like \externalfigure[dummy][width=auto,height=.5\textheight] but height and width only take dimensions. Can you give me a hint? Hraban

LMTX and soft links (Linux)
by Jairo A. del Rio 06 Jul '20

06 Jul '20

I'm using both LMTX from the ConTeXt standalone installation and a TeX Live installation. Since I'm using binaries from the standalone (and added LMTX to path, etc.), I created soft links in texmf-modules via ln -s /usr/local/texlive/2020/texmf-dist/tex ~/lmtx/tex/texmf-modules/tex and similar (lmtx is my directory for the standalone). LuaTeX finds files without any issues. However LuaMetaTeX gives the following error: runtime error : input file (name of file) is not found, quitting The same result is for modules, .sty files and .tex files. Is this intentional, a bug in LMTX, or is a better solution possible? In case it's useful, I'm working with Ubuntu 20.04. Thank you a lot. Jairo :)

ConTeXt source browser website update
by Taco Hoekwater 05 Jul '20

05 Jul '20

Hi all, I just replaced the software of https://source.contextgarden.net/ by a Lua implementation that uses Hans Hagen’s SciTE lexers for syntax highlighting and a Lua-generated search index. There is no official documentation yet (because I may want to change some stuff still) but here is some relevant information: * The search field uses a Lua string pattern to match a single word (no multi-word search as of yet). See https://www.lua.org/manual/5.3/manual.html#6.4.1 for the syntax of lua string patterns. * The search index only contains 7-bit ASCII ‘words’ that contain at least one of 'a-zA-Z’ (writing an LPEG for unicode matching is a tricky and probably would be quite slow even if I could make it work). Still, this should be ok-ish because most of the ConTeXt source is ASCII, except for the interface files. * The files context-en.xml, mtxrun{.lua}, and all of the files in the tex/context/patterns subtree are skipped in the search index. Also skipped are words shorter than 3 bytes, lua keywords, and words having more than (approx) 1500 hits * On the plus side, because of the SciTE lexer, “contextversion’ and “\contextversion” are separate entries in the search index. And you can search for “\@@kldirection”. * For text file types that have no SciTE lexer there is no syntax highlighting, and binary files are ignored altogether. The rest of the interface should be self-explanatory. Suggestions for improvements are welcome. Index statistics: 4085 files processed, 178 skipped, 3744 with matches 120733 words found 119154 words exported to word.idx 37928 comment words found 36880 words exported to comment.idx 26756 documentation words found 26018 words exported to docs.idx The word.idx is roughly 11 megabytes. Have fun, Taco

About some deprecated commands
by Jairo A. del Rio 05 Jul '20

05 Jul '20

Hi, list! I've realized the following commands commented in https://wiki.contextgarden.net/System_Macros/Expansion_Control no longer work in LMTX: \@EA \@EAEAEA \@EAEAEAEAEAEA One just could copy them from syst-aux.mkiv, but anyways. Should it be mentioned on the Wiki or something like that? Thank you very much. Jairo :)

Multiple cases of unexpected behaviour in luametatex
by Marcel Fabian Krüger 04 Jul '20

04 Jul '20

Hi, I recently noticed some cases where luametatex behaved in unexpected ways: - The "Extra \fi" error isn't triggered, instead an extra `\fi` freezes luametatex. (Can be reproduced by compiling a document which only consists of a single \fi) - token.new can only create some `data` tokens, but it doesn't apply bound checking on it's arguments: Take ``` \directlua{ t = token.new(0x200000, token.command_id'data') print(t.cmdname, t.command, t.mode) } ``` which prints register 102 0 The issue does not seem to be that such tokens do not exists because \letdatacode\somedata="200000 \directlua{ local t = token.create'somedata' print(t.cmdname, t.command, t.index) } does print data 101 2097152 Also for all other commands LuaTeX seems to apply range-checks to ensure that such overflows don't happen, even if invalid values are passed as firstargument. - There is token.primitives(). My assumption is that the returned table is meant to indicate the command is, mode and name corresponding to every primitive. (I think it is awesome that such a table is made available in luametatex) But especially the mode field sometimes has values which do not correspond to the mode of the actual primitives: I tried running the following in an almost iniTeX setting where all primitives aside from \shipout and \Umathcodenum have their default definitions: ``` \catcode`\%=12 \catcode`\~=12 \directlua{ local sorted = token.primitives() table.sort(sorted, function(a,b) return a[1]<b[1] or a[1]==b[1] and a[2]<b[2]end) for _,info in ipairs(sorted) do local t = token.create(info[3]) local rc, rm = t.command, t.mode if rc==info[1] and rm ~= info[2] then if info[2] == 0 then print(string.format('MODE MISMATCH, expected zero: \string\\%s: real: %i, command: %i', info[3], rm, rc)) else print(string.format('MODE MISMATCH: \string\\%s: offset: %i, command: %i', info[3], rm-info[2], rc)) end elseif rc~=info[1] then print(t.csname) end end } ``` This indicates that there are two kinds of differences: For some command codes, there are multiple primitives whose second entry in the token.primitives table is zero even though their mode is not zero. This especially affects the commands `above`, `after_something`, `make_box`, `un_vbox`, `set_specification` and `car_ret`. E.g. for after_something, all of \atendofgrouped, \afterassigned and \aftergrouped have a zero as second entry in token.primitives. The other difference is that all the internal_... commands have a fixed offset which differes between commands in their mode field. IMO the difference for the internal_... commands make sense because they make for easier to use numbers, but having multiple primitives indicating mode 0 for the other commands seems to make this table significantly less useful because it can't be used to get a unique description of a primitive. (I may have completely misinterpreted the table of course, but given that for other primitives the values match I do not think so) Best regards, Marcel

Converting a CSV file to a Lua table and Lua file
by Otared Kavian 04 Jul '20

04 Jul '20

Hi all, I have a bash script which converts a CSV file into a Lua table, which is then used in ConTeXt. It works fine, but I wonder whether there is a code within LuaMetaTeX for doing this directly there (writing a new file which contains the Lua table). This would be more efficient and neater. Thus a CSV file « example.csv » containing the lines: X,Y,Z 0.05597,0.6612,0.8618 0.156804,0.8784,0.961 0.496804,0.8784,0.9324 0.176804,0.648,0.9643 would be converted and wriiten into a lua file « example.lua » containing the lines: return{ -- {X,Y,Z}, {0.05597,0.6612,0.8618} {0.156804,0.8784,0.961} {0.496804,0.8784,0.9324} {0.176804,0.648,0.9643} } Thanks in advance for any help: Otared K.
