string.format changed in LuaTeX / grph-downsample
by Henning Hraban Ramm 23 Mar '18

23 Mar '18

Ahoi, since i recently updated my ConTeXt beta, Lua function string.format behaves differently, i.e. type checks are stricter. I guess it’s due to switching to Lua 5.3 in LuaTeX? E.g. this: if tonumber(string.format('%d', value)) == value then ... throws bad argument #2 to 'format' (number has no integer representation) Since I just need to check if the number is integer, this works: if tonumber(value) == math.floor(value) then ... This also affects Peter Münster’s grph-downsample module; please find a fixed version attached. (Decimal pixel sizes make no sense anyway, so I just "floored" them.)

\basegrid ignores color
by Henri Menke 23 Mar '18

23 Mar '18

Dear devs, The \basegrid macro ignores its color option. That's kind of obvious because as I look at the code I don't see the color being communicated to Metapost at any point. When you're at it, could you please also add a rulethickness parameters? Thanks! Reproducible in TL2018 pertest and latest beta. MWE is below (as always). Cheers, Henri --- \starttext \basegrid[color=red] \color[red]{\basegrid} \stoptext

Framed & before/after
by Procházka Lukáš Ing. 22 Mar '18

22 Mar '18

Hello, does \framed recognize before and after keys, as mentioned here: http://wiki.contextgarden.net/Command/defineframed or: http://wiki.contextgarden.net/Command/setupframedtexts ? In the following example it seems both keys are ignored: ---- \defineframed[AddressBox][before=\red,after=\small] \starttext \green A \AddressBox{\cldcontext{"Hele"}} B \stoptext ---- Best regards, Lukas -- Ing.

You're bitten by the cleaner that kind of normalizes entries as you can see when you say \enabletrackers[*sort*] replacing spaces by \0 can help but that sort of assumes that you know what happens inside So, i added some code to handle that. I also added a helper so that you can do: \startluacode local list = { -- old testament "Genesis", "Exodus", "Leviticus", "Numbers", "Deuteronomy", "Joshua", "Judges", "Ruth", "1 Samuel", "2 Samuel", "1 Kings", "2 Kings", "1 Chronicles", "2 Chronicles", "Ezra", "Nehemiah", "Esther", "Job", "Psalms", "Proverbs", "Ecclesiastes", "Canticles", "Isaiah", "Jeremiah", "Lamentations", "Ezekiel", "Daniel", "Hosea", "Joel", "Amos", "Obadiah", "Jonah", "Micah", "Nahum", "Habakkuk", "Zephaniah", "Haggai", "Zechariah", "Malachi", -- new testament "Matthew", "Mark", "Luke", "John", "Acts", "Romans", "1 Corinthians", "2 Corinthians", "Galatians", "Ephesians", "Philippians", "Colossians", "1 Thessalonians", "2 Thessalonians", "1 Timothy", "2 Timothy", "Titus", "Philemon", "Hebrews", "James", "1 Peter", "2 Peter", "1 John", "2 John", "3 John", "Jude", "Revelation", } sorters.definitions['bbt'] = { replacements = sorters.replacementlist(list), } \stopluacode \defineregister [booksort] [language=bbt, n=1, indicator=no] \starttext One \booksort{Genesis+5.2} Two \booksort{Exodus+2} Three \booksort{Genesis+45} Four \booksort{Philemon+2} Five \booksort{John+45} Six \booksort{1 John 1+45} Seven \booksort{2 John 2+45} \blank[3*line] \placeregister[booksort][language=bbt] \stoptext It probably makes sense to make this into a module but then we need to collect a few lists.
