scite module adds empty line at the end
by Wolfgang Schuster 26 Mar '20

26 Mar '20

Hi, when I use the scite module to format code blocks I get a empty line at the end of the environment. The cause for this is the "lines" environment used by the module which adds a \blank at the end. A custom lines environment without before/after values would help here. %%%% begin example \usemodule[scite] \setuptyping [TEX] [before=, after={\blank[back]}, after=] %\setuplines[after=] \starttext \ruledvbox\bgroup \startTEX \empty \stopTEX \egroup \stoptext %%%% end example Wolfgang

\tochar problem with symbols
by Wolfgang Schuster 10 Mar '20

10 Mar '20

Hi Hans, I encountered a nasty problem when I tried to make symbols for the Libertinus keyboard font. Whenever I tried to make a table with all symbols in the font ConTeXt stops with a error message. %%%% begin example \definefontsynonym [LibertinusKeyboard] [file:libertinuskeyboardregular.otf] \startsymbolset [libertinus-keyboard] [font=LibertinusKeyboard] % Libertinus Keyboard Regular \stopsymbolset \starttext \showsymbolset [libertinus-keyboard] \stoptext %%%% end example The error message is caused by two symbols in the font, the first is "bar" and the second is "dollar". The reason for this is that ConTeXt uses \tochar to auto create symbols in the font but \tochar set special catcodes for some letters. As can be seen in the example below "dollar" has catcode 3 and "bar" has catcode "13". %%%% begin example \starttext x\tochar{n:bar}|x \tochar{n:dollar}x$ \stoptext %%%% end example Wolfgang

Different Versions of Manuals
by Sebastian Miele 03 Mar '20

03 Mar '20

The ConTeXt Excursion referenced from the garden and contained in the LMTX distribution say that they are from 2017-Oct-05. The version linked from http://www.pragma-ade.com/overview.htm says it is from 1999-May-27. The ConTeXt reference manual linked from http://www.pragma-ade.com/overview.htm is from 2001-Nov-12. The version referenced in the garden is from 2013-Sep-27. As of now, I did not find a version of the document in the distribution. Neither in ConTeXt LMTX, nor in ConTeXt Standalone. In the following days I will start to use the most recent version of the two documents known to me. In the LMTX distribution: musings.pdf is from 2020-Jan-17, whereas musings.tex and musings-names.tex are from 2020-Feb-18. luametatex.pdf in LMTX is from Feb-18. In Standalone it is from Jan-30.

Typos in the LuaMetaTeX Manual
by Sebastian Miele 18 Feb '20

18 Feb '20

Some of these are up to two weeks old and may already have been fixed otherwise. "has resulted in many more parameters than were not accessible before": "than" instead of "that". "in a \atop stack": "a" instead of "an". "Method six omits the surround glue when there is (x)spacing glue present while method seven does the opposite, the glue is only applied when there is (x)space glue present too": The "too" at the end superfluous. Apart from that, the sentence says the exact opposite of what the preceding table says. At least one of them is wrong. "Note 1: for ease of use": "for" instead of "For". "so you you might encounter" "a \hbox": "a" instead of "an". The table for \mathscriptboxmode repeats 2 in the last two rows for the value column. In the last row it should be 3. "These primitives accepts an option width specification": "option" instead of "optional". "the fact if the used characters in the font have": "if" instead of "whether". "Commands like (plain TEXs) \big need use this feature": "use" instead of "to use". "These commands are provides as convenience": "provides" instead of "provided". The code example in 8.8.2 (Script commands \Unosuperscript and \Unosubscript) uses the wrong buffer. "and a character as nucleus. and which has the side effect that": Superfluous ". and". "(like kern and width, or data and value": Missing closing parenthesis. "and and" "A few more xperiments were done" "two kind of callbacks": "kind" instead of "kinds". "has to represent a hbox": "a" instead of "an". "<number prevdepth>": Probably should be "<number> prevdepth". "This callback replaces the code that prints LuaTeX’s when a file": "prints LuaTeX's" instead of "LuaTeX prints". Two occurrences of this typo (start_file, stop_file). "The value is currently": Swap "is" and "currently". "lua.setluaname(<string> s,<number> n])": A lone "]". "If you pass true to get you get 5 values returned for a glue and when you pass false you only get the width returned": This sentence only repeats something already mentioned in the same paragraph and can be deleted. "in which care only": "care" instead of "case". "the space before in between will be gobbled": The example code before that line actually uses "inbetween". "in between" probably is the correct spelling. "a callback that read numbers": "read" instead of "reads". "The engine can in one of four modes": "can in" instead of "can be in". "You can initialize with a new seed with init_rand (lua_math_randomseed is equivalent to this one": Somewhere in this sentence a closing parenthesis is missing. "This function behaves like texio.write, but make sure": "make" instead of "makes". "This function that should be used with care": Superfluous "that". "Normally a LUA will just collect prints": Something like "call" is missing after "LUA". "and as performance is quite ok. One can build additional parsers": Probably "ok. One" instead of something like "ok(,) one". "returns a number representing a dimension and or two numbers being the filler and order": "and or" instead of probably just "or". "The scan_code function takes an optional number, the keyword function": The "scan_code" has the prefix "scan_" in this sentence, the "keyword" does not, although it has in the preceding table. "returns a table of tokens tokens" "(for instance the catcode in case of a character or the classifier that determines the internal treatment": Missing closing parenthesis. In section 11.6.6 (Nota bene) the examples after "If we now say" do not change anything and seem to be superfluous, as far as I can see. "The argument hash can have a number of different fields": "hash" used to mean (hash) table. "Graphical objects come in various types that each has a different list of accessible values": "has a different list" instead of "have different lists". Or: "types that each" instead of "types. Each". Or: "types that each has" instead of "types, each having". "Each dash is two-item hash": Missing "a". Using "hash" to mean (hash) table. "The first argument is to be a page dictionary": "is" followed "to be". But more importantly: The sentence seems to make no sense in its context. "13.1.7 get[from][dictionary|array|stream]": Contrary to the section title, the section does not explain the getfrom.. stuff. That is handled in a separate following section. "The pdfe.new that takes three arguments:": "The pdfe.new that" instead of e.g. just "pdfe.new". "so that multiple doesn’t use more memory": Something is missing between "multiple" and "doesn't". And probably "don't" (plural). "an pdfe": "an" instead of "a". At least two occurrences of this. "puspose": instead of "purpose". The table explaining "readfixed2", "readfixed4", and "read2dot14" contains e.g. "a 2 byte float" in the results column. However, as far as I can see now, the functions probably read fixed point numbers of specific formats and return them as ordinary Lua (floating point) numbers. Similar considerations apply to other rows of the table. Maybe the results column should be separated into two columns: One on what is read from the stream, and one on how the result is represented and returned in Lua. "string.cWharacters" "Keep in mind that there might be platforms where this function is available": Probably a missing "not". Or "un" before "available". "The lua library provide some general helpers": "provide" instead of "provides". "Deep down some more has changes": Probably "changes" instead of "changed".

Minor Problems in the LuaMetaTeX Manual
by Sebastian Miele 16 Feb '20

16 Feb '20

"When you are processing a snippet of text starting with btex and ending with either etex or verbatimtex": According the MetaPost manual there are only "verbatimtex .. etex" blocks, but no "btex .. verbatimtex" blocks. "There is one special case: pens that are (possibly transformed) ellipses have an extra string-valued": In the current PDF, the "string-valued" gets hyphenated as "stringA" at the end of a line and "Bvalued" at the beginning of the following line.

time in downloaded attachments
by Pablo Rodriguez 13 Feb '20

13 Feb '20

Hans, would it be possible that "--remote-time" could be added to curl, so that attachments that are downloaded display when they were uploaded and not when they were downloaded? For some reason unknown to me, this seems to have no effect with http://lmtx.pragma-ade.nl/install-lmtx/installation.pdf (among many other ones). Timestamps work right when I download "curl -R -O http://lmtx.pragma-ade.nl/install-lmtx/installation.pdf" from the shell. Many thanks for your help, Pablo -- http://www.ousia.tk

Bug: Inline Math Surrounding Spacing
by Sebastian Miele 05 Feb '20

05 Feb '20

In the table on \mathsurroundmode in the LuaMetaTeX manual every example row has the same spacing, although there should be noticable differences. After trying to find the root of problem, I came to the conclusion that currently ConTeXt LMTX obeys neither \mathsurround nor \mathsurroundskip at all.
