A question about an algorithm environment

Hi Wolfgang, Why in the first example, the indentation of my Python code that I wish is not respected and that I have to do as the second example to have what I want ? Thank you.

Luatex 1.08.0 announcement
by luigi scarso 28 Oct '19

28 Oct '19

============================================================== LuaTeX 1.08 2018-08-28 ============================================================== (1) This release is a prelude to 1.10, the next stable iteration of LuaTeX after version 1.00. (2) Lua 5.3 is now considered to be default and we might use 5.4 in version 1.10. There are no real functional changed expected. You still need to rename the binary for 5.3! (3) Binary mode is no longer available in MPlib but it is still available in stand alone MetaPost. This simplifies compilation and reduces dependencies. (4) The dependency on Poppler for pdf image inclusion has been removed. We now use a small dedicated library written by Pawel Jakowski. We no longer need c++ compilers. We're in the process of making it behave well on all platforms. It has been tested on intel platforms. (5) We know that there can be some (alignment) issues with the arm platform but these are looked into. Therefore, later this year we will release 1.09. Version 1.10 is planned for TeXlive. We hope that ffi works ok on intel and arm platforms at that point. (6) There have been some extensions to the Lua libraries and some callbacks have been added. Also, a few new primitives have been introduced. The documentation mentions the stable extensions. (7) There are the usual bug fixes and cleanups but there have been no real fundamental changes in the API. The LuaTeX team

questions about publ-imp-apa.mkvi

Hello, Why do we have in publ-imp-apa.mkvi, line 1182 sq \btxdoif {number} { %\btxleftparenthesis (\btxflush{number} \btxrightparenthesis } and not \btxdoif {number} { \btxleftparenthesis \btxflush{number} \btxrightparenthesis } ? Damien Thiriet

typo in publications-customized.tex
by Damien Thiriet 28 Oct '19

Hello, I found a typo in publications-customize.tex. Here is a diff -u that may help to fix it quickly (not used to sending diff, I hope it'll help) --- publications-customize-patched.tex Mon Oct 28 07:26:37 2019 +++ publications-customize.tex Mon Oct 21 13:56:04 2019 @@ -362,7 +362,7 @@ diagnostics as described in the Appendices. Their functional meaning is rather \quote {handled} in contrast to \index {field+ignored}\quote {ignored}. \stopfootnote Note that if a category is \emphasis {not} declared in this \LUA\ -table, then \emphasis {all} of its fields will be considered \index +table, than \emphasis {all} of its fields will be considered \index {field+optional}\quote {optional}. Thus, ignoring this level of control and simply defining additional setups might be sufficient for most use. Regards, Damien Thiriet

cm unicode font: missing tounicode of oldstyle nums
by Ulrike Fischer 27 Oct '19

27 Oct '19

cmunrm.otf uses "unstandard" names for the glyphs of the old style numbers, e.g. oneoldstyle. This means that the glyphs don't get a tounicode mapping: \starttext \pdfvariable compresslevel=0 \font\test={file:cmunrm.otf:mode=node;script=latn;language=DFLT;+onum;}\test abc123 \stoptext gives 6 beginbfchar <0042> <0061> <0043> <0062> <0044> <0063> <0874> <FFFD> <0875> <FFFD> <0876> <FFFD> endbfchar The names are in glyphtounicode.tex, which contains e.g. \pdfglyphtounicode{oneoldstyle}{0031} So it doesn't looks as if they were completly unusual. Would it be possible to add tounicode mappings for these name? And how can one declare mappings for really unusual names? -- Ulrike Fischer https://www.troubleshooting-tex.de/

interlaced overbrace and underbrace
by mf 25 Oct '19

25 Oct '19

Hello list, is there a better way to interlace overbraces and underbraces like this? \starttext These are the expressions to combine: $$\overbrace{a+b+c}+d \quad a+\underbrace{b+c+d}$$ This is the desired result: $$\overbrace{a+b+c}+d \kern-16mm\underbrace{\hbox to 15mm{ }}$$ \blank {\tfx(the underbrace should move down a little more)} \stoptext TIA, Massi

place single entry of a register, or filtering the terms of a register
by mf 25 Oct '19

25 Oct '19

Hello list, is there a way to place only one single entry of a register, or a selection of entries? I looked into strc-reg.mkiv and strc-reg.lua and i would answer "no, it's not possible". I could hack strc-reg.lua and define a command to do that, but maybe a better solution is already there. Here's a very simple MWE to work on, in case it's possible: \starttext Cat\index{cat}, mouse\index{mouse}. \page Cat\index{cat}, dog\index{dog}. \page \placeindex \page Here I'd like to place only the "cat" entry:\par \placeindex[criterium=???] \stoptext Massi

Luacode: Data File to Table
by Rudolf Bahr 24 Oct '19

24 Oct '19

Hi All! LuaMetaTeX, Version 2.00.0 ConTeXt ver: 2019.10.10 18:15 MKIV beta fmt: 2019.10.19 int: english/english I'd like to transfer the entries in a data file to a Lua table according to [1]. Here a MWE of my data file, appended as file Rosi.lua: -------------------------- Rosi{ smrk = "00-003", picture_file = "/home/sam/pictures/", picture_name = "00-003---1981---Provence.png", width_px = "394", height_px = "481", } Rosi{ smrk = "00-006", picture_file = "/home/sam/pictures/", picture_name = "00-006---1986---Eire.png", width_px = "392", height_px = "479", } And here is my MWE in Luacode: ------------------------------ \startluacode userdata = userdata or {} u = userdata function u.Hugo ( ) local S = {} function Rosi (b) S [ b.smrk ] = { [ "smrk" ] = b.smrk, [ "picture_file" ] = b.picture_file, [ "picture_name" ] = b.picture_name, [ "width_px" ] = b.width_px, [ "height_px" ] = b.height_px, } context ( 'function Rosi(): b.smrk = ', b.smrk ) context.par() end require ("Rosi") end \stopluacode \starttext \currenttime \def\Heidi% {\ctxlua{u.Hugo()}} \Heidi \stoptext The entries in Rosi.lua aren't recognized in Luacode! The output pdf is appended as well. Now the essential part of the MWE above in pure Lua. Here it works! Strange. ----------- userdata = userdata or {} u = userdata function u.Hugo ( ) S = {} function Rosi (b) S [ b.smrk ] = { [ "smrk" ] = b.smrk, [ "picture_file" ] = b.picture_file, [ "picture_name" ] = b.picture_name, [ "width_px" ] = b.width_px, [ "height_px" ] = b.height_px, } print ( "b.smrk = " .. b.smrk ) end require ("Rosi") print ( S["00-003"]["width_px"], S["00-003"]["height_px"] ) print ( S["00-006"]["width_px"], S["00-006"]["height_px"] ) end u.Hugo () Please, what could be done?
