Nestable environments with parameters?
by Brooks Moses 02 Oct '05

02 Oct '05

Hello again! I've actually got a solution to this problem, but I'm not particularly happy with it and would like to know if there's a better way -- or, for that matter, a more "standard ConTeXt" way -- of solving it. I'm building an environment that I'd like to be able to use in the following way: \setupmyenv[paramA=This] \startmyenv[paramA=That] A bit of text. \startmyenv More text. \stopmyenv \stopmyenv In particular, when it's used this way, I would like the inner environment to use the "This" version of paramA, rather than the "That" version. Moreover, since the parameter-handling code is (in the real example) fairly complicated, I'd like to reuse the same macro to handle it in both the \setupmyenv and the \startmyenv cases. I'm currently doing this in the following way: * \setupmyenv calls \getparameters[\??myenv][#1], where \??myenv was created with \definesystemvariable{myenv}. This creates a set of \@@myenvparamA and related macros containing all the global settings. * \startmyenv calls \copyparameters[\??myenv_][\??myenv][...], thereby copying all of the defaults into \@@myenv_paramA and so forth, which provide "local" values of all of the settings. * \startmyenv then calls \getparameters[\??myenv_][#1], thus overwriting the relevant local settings -- but not the global settings -- with the new values. The two \getparameters commands (and the stuff that surrounds them) is identical aside from "\??myenv" versus "\??myenv_", and thus can be enclosed in a shared macro. Also, since \startmyenv does all this in a group, the local settings on the inner environment don't contaminate the ones in the outer environment. This works, but I'm not especially happy with it -- the \copyparameters gets called every time the environment is started, and this seems rather a lot of excess work when most of the values don't change. It's also a source of programming errors, because I have to remember to update the list each time I change it. Any suggestions for a better solution? I couldn't find any environments in the ConTeXt core that do this sort of nesting.... Also, I'm trying to follow "ConTeXt standard style" as much as possible in this -- I'm hoping to write up a TUGboat article on it eventually -- and, while the trailing underscore works perfectly well to create a "local" version of a "global" variable, I'm wondering if there's a more standard way of doing that.... Thanks! - Brooks

Idris Samawi Hamid said this at Mon, 26 Sep 2005 12:52:56 -0600: >Apparently \incrementnumber[footnote] only works for n>1. Not entirely. There's also an interaction with grouping. So, there has to be a footnote used ungrouped before the number can be manipulated. {Title\footnote{test}} % 1 {Title\footnote{test}} % 2 \incrementnumber[footnote] Test\footnote{test} % 4? huh. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

Yet another footnote bug (or two).
by Brooks Moses 27 Sep '05

27 Sep '05

Again, from playing with footnote examples on the Wiki. \starttext {\bfd This is text\footnote{And a footnote.}.} This is text\footnote{With a footnote.}. \stoptext The footnote symbol shows up appropriately sized for normal text, not for the extra-large text. (It is boldface, though.) On the other hand, in chapter headings, the opposite problem occurs -- the footnote is too large. Note, in the following example, that the footnote in the chapter heading is a good bit larger than the x-height of the neighboring font, whereas the footnote in the ordinary text is a little bit smaller than the x-height of the neighboring font. \starttext \chapter{This is a chapter\footnote{And a footnote.}.} This is text\footnote{With a footnote.}. \stoptext - Brooks

Typesetting ConTeXt modules?
by Brooks Moses 20 Sep '05

20 Sep '05

Hello! How does one go about converting ConTeXt module files (such as syst-ext.tex and so forth) into typeset documentation? I saw the modules.zip file that Luigi Scarso uses to create his modules.pdf file, here: http://wiki.contextgarden.net/User:Luigi.scarso/modules.pdf But that seems to rely on something else converting the .tex file from the module into a .ted file, and I haven't been able to figure that out on my own.... - Brooks

Hi, This sounds like a bug. (there is no point in having a switch if you cannot safely turn it off) Taco Giuseppe Bilotta wrote: > > No, it was because I had disabled \preloadfonts. > Interesting.

Determining the current text style?
by Brooks Moses 12 Sep '05

12 Sep '05

Hi! I'd like to write some macros that do different things depending on the style of the current font. That is, \mymacro in this example \mymacro {\bf \mymacro} {\it \mymacro} should be able to do something different in each of those three cases. I remember seeing a bit of clever code in a recent message that could test whether or not it was being used in a region of typewriter font and adjust accordingly; are there similar tests that can be used for \bf, \it, and so forth? If so, what are they? (And how reliable are they?) (For those who are curious, I'm thinking about this for the LaTeX-compatiblity code I'm writing. LaTeX's \itshape command will select \it in normal font, but \bi in boldface font. LaTeX handles this by defining extra flags to keep track of the current style, but I'd like to avoid doing that if I don't need to.) Thanks, - Brooks
