Comma lists and Lua
by Wolfgang Schuster 07 Jun '12

Hi, in the following example the space before the “one” in the line \ctxlua{userdata.commalist(" one, two, three")} is visible in the output. I guess this counts as bug because in the assignment list the space before “a=x” is removed. Example: \starttext \startluacode userdata = userdata or {} function userdata.commalist(list) local list = utilities.parsers.settings_to_array(list) context.starttabulate() for index, value in next, list do context.NC() context.quotation(index) context.NC() context.quotation(value) context.NC() context.NR() end context.stoptabulate() end function userdata.parameters(list) local list = utilities.parsers.settings_to_hash(list) context.starttabulate() for key, value in next, list do context.NC() context.quotation(key) context.NC() context.quotation(value) context.NC() context.NR() end context.stoptabulate() end \stopluacode \ctxlua{userdata.commalist("one,two,three")} \ctxlua{userdata.commalist(" one, two, three")} \ctxlua{userdata.parameters("a=x,b=y,c=z")} \ctxlua{userdata.parameters(" a=x, b=y, c=z")} \stoptext Wolfgang

Including gif images from the web
by Aditya Mahajan 31 May '12

31 May '12

Hi, Inclusion of gif images from the web does not work. For example: \starttext \externalfigure[http://upload.wikimedia.org/wikipedia/commons/a/a0/Sunflower_as_gif_websafe.gif] \stoptext It is a rather strange bug. In grph-inc.lua we have local newbase = file.addsuffix(newbase,newformat) local newname = file.join(newpath,newbase) Now, since the webaddress has a dot, newbase has a dot. file.addsuffix does not change the suffix if a file already has a suffix (and does not give any warning about it!). So, newname does not end with .pdf, and therefore gm convert long-path.gif long-path does not convert to pdf--the resultant file is a gif file. Hence, direct inclusion of that file fails. A simple fix is to change the addsuffix line to: newbase = newbase .. "." .. newformat Aditya

Users can do \setupframed[mine:whatever=wewant] and then say \framedparameter{mine:whatever}. They never see or use the #1 (being a special and abstract namespace value). It's the value of \currentframed that starts the lookup chain. Also, a lot of this low level code is optimized for performance.

Definition of \doframedparentparameter
by Marco 28 May '12

28 May '12

Hi, I have a question about \doframedparentparameter from pack-rul.mkiv: \def\doframedparentparameter#1#2{\ifx#1\relax\doframedrootparameter#2\else\doframedparameter#1{#2}\fi} When the else branch is taken, it picks up the second argument, but when the if branch is taken, it just picks up the first letter of the argument (since the braces are missing). Is that intended? When there are braces in the else branch there should also be braces in the if branch. Marco

Local settings for frame borders
by Aditya Mahajan 28 May '12

28 May '12

Hi, Currently it is not possible to individually set the thickness of the different borders of a frame. A typical use-case is typesetting a table row where the top frame is double the thichness of the bottom frame. Having to resort to metapost for something as simple as this is a bit annoying. Attached is a metapost library that defines "local" fences and allows you to set border individually. For example \defineframed[...][frame=off, topframe=local, topframethickness=1pt, bottomframe=local, bottomframethickness=0.5pt] sets the top frame to be 1pt and the bottomframe to be 0.5pt. Does it make sense to include this (appropriately modified) in the core? Or is it better to distribute such enhancements as a user module. Aditya
