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

Some questions about punctuation squeezing in Japanese

hi,lists The punctuation of question marks, exclamation marks, and quotation marks doesn't seem to be very good at the moment. ipaexgothic font download : https://moji.or.jp/ipafont/ipaex00401/ %%%%%%%% \starttext \definedfont[name:ipaexgothic] \startscript[nihongo] \setbox0\hbox{% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% \framed[width=1em,height=.8em,depth=.2em,strut=no,framecolor=red]{}% }\leavevmode\smash{\copy0}\hskip-16em（あ）。亂數：「假，文。」「亂數」 <== work well \leavevmode\smash{\copy0}\hskip-16em 亂數、「假文？」「亂數！」假文」。亂數 <== not good with {\red？」} and {\red！」}. \\ ==>{\red？} and {\red！} should be full-width with {\red」}. just like {\red ？{}｣} \leavevmode\smash{\copy0}\hskip-16em 亂數：“假文。”亂數：“假文？”亂數：“假文！” <== not good with {\red：“} and {\red。”} and {\red？”} and {\red！”}.\\ ==>{\red “ ”} should be half-width with {\red 。？！}. just like {\red「」} \leavevmode\smash{\copy0}\hskip-16em 「ちょっと」，“チェック”亂數・假文 <== not good with {\red ，“}. \\ ==>the space between {\red ，} and {\red “} should be half-width \stopscript \stoptext thanks for any help, autumnus

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
