m-graph read data and plot
by John Kitzmiller 06 Aug '15

06 Aug '15

Given a file, data.d, containing 1 4 7 I expected the following code to draw a line from (4,1) to (7,1)… \enabletrackers[metapost.showlog] \usemodule[m-graph] \startMPpage[instance=graph,offset=3mm] draw begingraph(5cm,5cm); gdata("data.d", v, for n = 1 upto 3: a[n] = scantokens v[n]; endfor; show a1; show a2; show a3; % numeric show v1; show v2; show v3; % string gdraw (a2,a1)—(a3,a1); % same problem in or out of data group ); endgraph; \stopMPpage …the show lines return what I expected, but then come the complaints: ! Inconsistent equation (off by 0.90000000000000002)… >> (0,0,1,0,0,yypart S) ! Transform components aren't all known… My goal is to draw multiple box plots https://en.wikipedia.org/wiki/Box_plot <https://en.wikipedia.org/wiki/Box_plot>, either vertical or horizontal, from data sets, but I am stuck at this early stage.

Formatting footnotes
by robheus 06 Aug '15

06 Aug '15

Hello list, I want some adjustments to my footnotes. 1. The note number in the footnote needs to be normal instead of superscript. 2. The placement of the number is now in the margin, but needs to be in the normal starting position of body text. Of course the foot note texts then has to shift accordingly to the right, and leaving enough room for footnote numbers not exceeding 99. How do I dot this? Greetings, Rob

local environment?
by talazem＠fastmail.fm 05 Aug '15

05 Aug '15

Dear all, What is the replacement for `localenvironment` in project structures? The first part of my book has one layout; the second has another. I have designed one environment for the first part, and another environment for the second. I do not want the first environment to be used for the second half of the book. In cont-eni.pdf, I read about using `localenvironment` for such scenarios, but it seems this has been removed. This is probably a very basic question, but how do I should change the following such that *one pdf* is produced, where the first part—ComponentA—uses EnvironmentA’s layout, while the second part—ComponentB—uses EnvironmentB's. If any startsetups need to be defined, I’d be grateful for any example, showing also where to place them. # Product \startproduct MyProduct \component ComponentA \component ComponentB \stopproduct # EnvironmentA \startenvironment envA % the definitions \stopenvironment # EnvironmentB \startenvironment envB % the definitions \stopenvironment # ComponentA \environment envA \product MyProduct \startcomponent ComponentA \starttext … \stoptext # ComponentB \environment envB \product MyProduct \startcomponent ComponentA \starttext … \stoptext --- With thanks, Talal

Is this a bug?
by Matt Gushee 04 Aug '15

04 Aug '15

Hello, all-- I asked this question a few days ago, in the context of solving a problem I was having. That problem is solved, thanks to Wolfgang, but I haven't seen any response to my mention of what I think is a bug. The issue I was having was that, when I tried to process an old project with mkIV, there was no output because the project structure was obsolete: it contained a project and several products, but no components. But even though there was no output, there was also no error message, and in fact the log file falsely reported that a PDF file had been saved. That can't be right, can it? Seems like a bug. My ConTeXt version is: current version: 2015.05.18 12:26 -- Matt Gushee

r2l alignment and linenumbering conflict?
by talazem＠fastmail.fm 04 Aug '15

04 Aug '15

There seems to be some limitation (or bug) in right-to-left (r2l) alignment, when used alongside linenumbering. Consider the following: > \setuppapersize[A6] > \starttext \showframe > > \section{Incorrect} > \startlinenumbering > \startalignment[r2l] > Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque molestie dictum quam non congue. Integer ut dolor vel mi vestibulum molestie vel et nulla. > \stopalignment > \stoplinenumbering > > \section{Correct} > \startalignment[r2l] > Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque molestie dictum quam non congue. Integer ut dolor vel mi vestibulum molestie vel et nulla. > \stopalignment > > \stoptext The RTL alignment works correctly on its own. However, when you introduce another factor — here, linenumbers — the RTL alignment is ignored. Perhaps this linked to the problem with of RTL footnotes being discussed here: gmane.comp.tex.context/92113 <http://article.gmane.org/gmane.comp.tex.context/92113>? Best wishes, Talal

Formatting footnotes - conditional rule
by robheus 04 Aug '15

04 Aug '15

Hello list, Formatting footnotes allows defining wether the rule is on or off, seperating normal text from the foot notes. Can it be implemented in Context to display the footnote rule depending on wether either a new footnote begins (fist line starts with foot note number) or the footnote text is a continuation of a footnote started on a previous page? Thanks, Rob

ending every paragraph
by Idris Samawi Hamid ادريس سماوي ح امد 04 Aug '15

04 Aug '15

Dear gang, Suppose I want to end the last line of every paragraph with a command, say, \thinrule, or a string of dots. Is there a straightforward way to do that? TeX has \everypar but I'm not aware of any, say, \endeverypar command. Best wishes Idris -- Idris Samawi Hamid Professor of Philosophy Colorado State University Fort Collins, CO 80523
