Handling of negative values in the statistical-charts?
by Ramkumar KB 28 Aug '21

28 Aug '21

Dear List, I have been exploring the use of the awesome statistical-charts <https://akela.mendelu.cz/~thala/statcharts/> module. So first of all, a big thanks to the authors of the same. I seem to have hit a snag when it comes to handling of -ve values. In my example (attached tex & pdf), the y-axis labels and the grids do not seem to be working on the -ve side (also, able to flip labels above x-axis for -ve values). This seems to be the case of column charts and bar charts (and I will test this for the other types of charts also). If this is a more generic issue across all the types, then I can contribute towards enhancing it (as any charts module should handle -ve values). Any tips or pointers would be really helpful. Thank you very much. best regards,

prefixstarter in captions
by Adam Reviczky 28 Aug '21

28 Aug '21

Hi, There was a question on the list before on prepending to the numberpart of a caption with the 'numberstarter' command, which works just fine ( https://mailman.ntg.nl/pipermail/ntg-context/2017/089142.html) I wanted to try the same but for prepending to the entire prefix (not just the number part) when prefixsegments are used, however using 'prefixstarter' does not seem to make a difference. For the sake of the example I have added the numberstarter in as well, just for comparison. Caption with the example reads "Figure 1.S.1" whereas I was expecting "Figure C.1.S.1". MWE: \setupfloatcaption[figure][number=yes,way=bytext,prefix=yes,prefixstarter={C.},numberstarter={S.}] \starttext \startchapter[title={Cow}] \startplacefigure[title={Custom caption}] \externalfigure[cow] \stopplacefigure \stopchapter \stoptext Not sure whether prefixstarter is the intended command to use, but the wiki of setupcation (https://wiki.contextgarden.net/Command/setupcaption) says it inherits from setupcounter which has both numberstarter and prefixstarter defined in the same way.

Re: [NTG-context] Test for displaying a header

Fabrice, there is difference between putting something on the first page regardless of the number of pages in your document or do something when your document contains only a single or more pages. When you have a header or title which is always placed on the first page (but not on the following pages) you have to options. 1. Check the current page when to header is placed which can be done with \doif{\pagenumber}{1}{...} 2. Disable the header on the first page (\setupheader[state=high]) and place your own title as a regular element in the running text. A case where you have to number the number of total pages is when you try to show the page counter in the form "Page x of y" for 2 or more pages. In this case you have to check against the value for the total number of pages which can be done with \doifnot{\totalnumberofpages}{1}{...}. Below are two examples which show how the header/title placement works. %%%% start example 1 \startsetups [header] \startframed [width=max,height=max] First page header \stopframed \stopsetups \startsetups [footer] Page \userpagenumber\ of \lastuserpagenumber \stopsetups \setupheadertexts [\doif{\pagenumber}{1}{\directsetup{header}}] \setupfootertexts [\doifnot{\totalnumberofpages}{1}{\directsetup{footer}}] \starttext \dorecurse{12}{\samplefile{lorem}\par} \stoptext %%%% stop example 1 %%%% start example 2 \startsetups [header] \setupheader[state=high] \startframed [width=max,height=3cm] First page header \stopframed \blank \stopsetups \startsetups [footer] Page \userpagenumber\ of \lastuserpagenumber \stopsetups \setuppagenumbering [location=none] \setupfootertexts [\doifnot{\totalnumberofpages}{1}{\directsetup{footer}}] \starttext \setup[header] \dorecurse{12}{\samplefile{lorem}\par} \stoptext %%%% stop example 2 Wolfgang

getting path and filename from url
by Pablo Rodriguez 28 Aug '21

28 Aug '21

Dear list, I have the following sample: \starttext \startluacode url = "../a/b/cb/ce.b/ca.b/c/dabc.pdf" context(url) context("\\\\0 ok. " .. url:match "^(.*).pdf$") -- name and path context("\\\\1. " .. url:match "^(.*).+$") -- path context("\\\\2. " .. url:match"[^/]+[.$]") -- name context("\\\\3 ok. " .. url:match "[^.]+$") -- extension \stopluacode \stoptext How can I get that match for #1 ends in the last slash (including it "../a/b/cb/ce.b/ca.b/c/") and match for #2 ends in the last period (excluding it, "dabc")? Many thanks for your help, Pablo -- http://www.ousia.tk

Different author rendering in entry citation vs. list
by Joey McCollum 27 Aug '21

27 Aug '21

Hi, I'm trying to implement a custom bibliography rendering where in-text citations (specifically, citations with alternative=entry) are not identical to the entries in the bibliography list. Following a pattern I've seen in publ-imp-chicago.mkvi, I've been able to implement most of the features I'm interested in by using conditional formatting with a mode that is specifically set for citations with the "entry" alternative. I'd also like for author names in entry citations to be different author names in list entries, in the following ways: - In entry citations, authorconversion should be normal, while in list entries, authorconversion should be inverted (more specifically, the first name should be inverted, while all subsequent names should be in normal order...but if this is too complicated, then it may be an issue for another e-mail thread, and we can just focus on normal vs. inverted for now). - In entry citations, "et al." should be used for any names after the third name, while in list entries, all names should be printed in full. I thought that the following settings would work: \definebtx [sbl:\s!list] [sbl] [\c!otherstext=, \c!etallimit=, \c!etaldisplay=, \c!etaloption=, \c!authorconversion=inverted] % TODO: need to print the first name inverted, with all subsequent names in normal order \definebtx [sbl:\s!cite] [sbl] [\c!otherstext={\btxspace\btxlabeltext{others}}, % use et al. for truncated author / editor list \c!etallimit=3, % don't use et al. for 3 or fewer authors \c!etaldisplay=3, % \c!authorconversion=\v!normal] % by default, use normal name order for in-text citations But only the "list" settings seem to be used. I suspect this might be because the setup for "entry" citations invokes \btxhandleciteentry and therefore uses "list" settings everywhere except where I check modes for conditional formatting. But is there a command or environment I can use to change authorconversion locally, based on the current mode, in the helper methods I've defined for rendering bibliography entries? Thanks! Joey

The layout on the first page is different from the following pages but this is just how \definelayout work when you use a number as first argument. What you have to understand is that a setups-environment is just a macro definition where you provide the names as argument to the start command. This means \startsetups [header] ... \stopsetups works the same way as \def\internalname_header {...} but you have to use \setups [header] rather than \internalname_header to get the content of the environment.

Indexing redux
by Rik Kabel 26 Aug '21

26 Aug '21

List, I am trying to create an index with both "see" and "see also" cross-reference entries.[1] At this point, ConTeXt provides basic support for "see" entries via the \seeREGISTER command (it does not properly support references to sub-entries) and it provides no support at all for "see also" entries. Can somebody suggest a way to generate these entries? Perhaps a way of inserting entries into the index before it is formatted, in the manner of \writetolist or \writebetweenlist? (MkII has \writetoregister, but that did not carry forward and I do not know if it would have helped here.) I had brought this up to no response a couple of years ago.[2] I am hopeful that LMTX may offer a chance to get support for improved indexing, and in particular for "see" and "see also" entries. [1] For definitions and usage of "see" entries, see https://docs.oasis-open.org/dita/v1.1/OS/langspec/langref/index-see.html. For "see also" entries, see https://docs.oasis-open.org/dita/v1.1/OS/langspec/langref/index-see-also.ht…. For a deeper dive, see the publicly available University of Chicago Manual of Style version 15 guide, chapter 18, available at https://press.uchicago.edu/Misc/Chicago/CHIIndexingComplete.pdf, or more recent versions not yet freely available online. [2] See "Possible seeindex enhancement" at https://www.mail-archive.com/ntg-context@ntg.nl/msg89470.html. -- Rik
