[ \startTEXpage with \strut ]
by vm 08 Dec '24

08 Dec '24

Trying to get a single page of a specific size, I set the width and height of \startTEXpage only to find out that a \strut as a last command before the \stopTEXpage, will expand the height. 8<---- \setuppapersize [A2] \starttext \startTEXpage[offset=0mm, width=220mm, height=110mm] MWE without \type{\strut} -> Landscape (220 × 110 mm) %MWE with \type{\strut} -> Landscape (220 × 111 mm) %\strut \stopTEXpage \stoptext --->8 There if probably a reason to it, so I'd like to know why it works as it does. .F

Roman numerals typography
by damien＠thiriet.web4me.fr 07 Dec '24

Hello, In French typography, roman numerals are usually typeset being connected with a top bar and a lower bar, at least when it comes to century numbers (should be also small caps, something I discovered today). Since I am not sure my vocabulary suits to this reality, you can see a sample looking at photos displayed in this online article https://fr.cultura10.com/r%C3%A8gles-d%27%C3%A9criture-des-nombres-romains/ I have been simulating this with kerning for several years, but I recently switched from Latin Modern Sans to Luciole (both 24pt) for my presentations and I have to redesign this issue. So it is a good opportunity to find some a better alternative than stuff like \def\III{{\rm I\kern -1.3pt I\kern -1.3pt I}}, working at the font level or with a ConTeXt built-in macro. Several questions: 1) Is this already implemented in ConTeXt (I don't have time to reinvent the wheel once more)? The sample I looked at in the \Romannumeral wiki page doesn't implement this, but they may be alternative I am not aware of. 2) If it isn't, I think the best way would be to add a font extension, using hits given by Hans in the 11th meeting proceedings. However, what would be the best idea: playing with kerning, or with ligatures? Thanks for your advices, Damien Thiriet

Rounded pens with Metapost

Hi, are there now better ways to create rounded pens without adding many support points? \starttext \startMPpage[offset=1dk] path Halfcircle ; Halfcircle = (1,0){up} for i = 1 upto 180 : .. ((1,0) rotated i) endfor -- cycle ; draw Halfcircle scaled 10 shifted (0,12) ; pen HalfcirclePen ; HalfcirclePen := makepen Halfcircle ; draw ((0,1) -- (1,1)) scaled 10 withpen HalfcirclePen ; draw ((0,0) -- (0,1)) scaled 10 withpen HalfcirclePen rotated 90 ; draw ((1,0) -- (1,1)) scaled 10 withpen HalfcirclePen rotated 270 ; draw ((0,0) -- (1,0)) scaled 10 withpen HalfcirclePen rotated 180 ; \stopMPpage \startMPpage[offset=1dk] path RoundedRectangle ; RoundedRectangle = (-1,0){up} for i = 180 step -1 until 89 : ..

month form \currentdate in Roman numerals
by Pablo Rodriguez 07 Dec '24

07 Dec '24

Dear list, I would like to get the current month in Roman numerals (just now, it would be XII for December). The best I get is: \currentdate[\cldcontext{converters['R'] (tonumber(os.date("\letterpercent m", os.date(os.time()))))}] This strikes me as too complex (even for someone who cannot code). Is there now simpler way to write that? Just in case it may be relevant, this is part of the full day reference. Many thanks for your help, Pablo

Transition from ConTeXt mark II to mark IV
by Michal Kvasnička 06 Dec '24

06 Dec '24

Hallo. I need some help. I have all my teaching materials (slides, worksheets, and everything, including many MetaPost figures) in ConTeXt mark II. After the transition to Ubuntu 24.10, I found that the texexec is not a part of the ConTeXt distribution anymore. I tried to compile my stuff with context instead and failed. This is probably because the macros in my old modules (created by myself many years ago) are not compatible with mark IV. Hence my question: Is there any document on the transition from mark II to mark IV? Many thanks for your kind help. Best wishes, Michal

Hiding a part of a path
by Jeong Dal 02 Dec '24

02 Dec '24

Dear all, I’d like to hide a part of a path. I can do that after changing it into an image, but it is not clearly erased. Is there a way to do that not changing it into an image? Thank you for reading. Best regards, Dalyoung \startMPcode path p,q; picture pic; numeric u; u:= 1cm; p := origin--(2u,0)--(3u,u)--(3u,0)--(4u,0); q := (3u,u)--(3u,0); pic := image(draw p; draw q withcolor white;); draw pic; \stopMPcode

Metapost lines with fancy line endings and connections
by Wolfgang Schuster 01 Dec '24

01 Dec '24

Hi, I have a bunch of similar graphics on a 7x7 where some lines have exceptions for the endings and connections. - When a line ends in one of the four corners the line end has an angle of 45 degrees. - When a line takes a turn the outer corner results also in a 45 degree angle. - Single points always use straight endings. - Lines which end outside of a corner end with a straight line. While I can get the desired result which a filled path I'm looking for a solution where I have to set fewer control points. The example below shows the simpler draw alternative where I need only a start and end point versus the outline alternative where I need at least twice as many points to get the desired output. \starttext \startuseMPgraphic{draw} draw hlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 shifted (0.5,0.5) withcolor "darkgray" ; draw vlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 shifted (0.5,0.5) withcolor "darkgray" ; pickup pensquare scaled 1; drawoptions(withcolor "red"); draw (1,7) -- (7,7) ; draw (1,1) -- (3,1) -- (3,5) ; draw (7,3) -- (5,3) -- (5,5) -- (7,5) ; draw (7,1) ; \stopuseMPgraphic \startuseMPgraphic{fill} draw hlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 withcolor "darkgray" ; draw vlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 withcolor "darkgray" ; drawoptions(withcolor "green"); fill (0,6) -- (7,6) -- (6,7) -- (1,7) -- cycle ; fill (1,0) -- (2,0) -- (3,1) -- (3,5) -- (2,5) -- (2,1) -- (0,1) -- cycle ; fill (7,2) -- (5,2) -- (4,3) -- (4,4) -- (5,5) -- (7,5) -- (7,4) -- (5,4) -- (5,3) -- (7,3) -- cycle ; fill (6,0) -- (7,0) -- (7,1) -- (6,1) -- cycle ; \stopuseMPgraphic \startcombination[2*1] {\scale[s=10]{\useMPgraphic{draw}}}{draw option} {\scale[s=10]{\useMPgraphic{fill}}}{fill option} \stopcombination \startoverlay {\scale[s=10]{\useMPgraphic{draw}}} {\scale[s=10]{\useMPgraphic{fill}}} \stopoverlay \stoptext Wolfgang
