Hello everyone, first off: I am new to ConTeXt (even if not so new to LaTeX) and would like to transfer some of my old macros to ConTeXt... I am well aware, that this means re-programming (most) of them. So be it. Furthermore, I am not sure if this is really the right way (read ConTeXt Way) to do it. It just looked like a good idea at the time ... However, I just hit a snuff with the following: If one places \NewIssue[Some Time] somewhere in the text, it should result in a new (issue / timestamp) to be generated, which can then placed in a list of issues / changes. I also want to be able to make use of the last value Issue to be placed in the header, same goes for the last timestamp Now this is how I went out to do this in ConTeXt (maybe wrongly so?) following the manual and some examples on contextwiki %--------------- code below ----------------------- \definesynonyms[Issue][issues][\IssueText][\IssueDate] \setupsynonyms[Issue][criterium=all] \newcounter\IssueCounter \definenumber[IssueNumber] \def\TempIssueText{% %% This was the (seemingly) only way to get any value beside 0 %% from \getnumber within doAddIssue %% Original place for \incrementnumber[IssueNumber] Issue~\getnumber[IssueNumber]: } \def\NewIssue{\dosingleargument\doNewIssue} \def\doNewIssue[#1]{% \increment\IssueCounter % This one works correctly. %% Alternative place for %\incrementnumber[IssueNumber] %% if placed here instead of in \TempIssueText %% a DIFFERENT, but still wrong result comes out %% that is: Debug shows the right progression, %% but ALL "Issue x" Numbers are set to the last one Debug: \IssueCounter / \getnumber[IssueNumber]% %% but alas I can't seem to make this work with the following lines :-( \doifempty{#1}{\Issue[\IssueCounter]{\TempIssueText}{\currentdate}} \doifnotempty{#1}{\Issue[\IssueCounter]{\TempIssueText}{#1}} %% Note: Using \dofiemptyelse gives the same result, %% I just wanted to make sure here that I am /really/ not calling it twice, %% somehow, by being able to disable each case, separately and definitely. -- \IssueCounter / \getnumber[IssueNumber] \crlf } % -- -- -- -- -- -- \starttext \NewIssue[January 9, 2008] \NewIssue[January 10, 2008] \NewIssue % January 11, 2008 List of issue \# and dates: \placelistofissues \blank \IssueDate{\IssueCounter} % produces correct result in either case \stoptext %--------------- code above ----------------------- Result as printed out by original version ---------------------------------------------- Debug: 1/ 0 – 1/ 0 Debug: 2/ 0 – 2/ 0 Debug: 3/ 0 – 3/ 0 List of issue # and dates: Issue 2: January 9, 2008 Issue 4: January 10, 2008 Issue 6: January 11, 2008 January 11, 2008 ------------------------------ So while \IssueCounter is updated correctly and used with the right values, \getnumber[IssueNumber] always sees / reports the original value However, the value in \placelistofissues are twice what they should be?! This is changed if one places \incrementnumber[IssueNumber] INSIDE of \doAddIssue Here, \getnumber[IssueNumber] does report the right value (same as IssueCounter) However, in that case the result looks like this: Result as printed out by alternative version ---------------------------------------------- Debug: 1/ 1 – 1/ 1 Debug: 2/ 2 – 2/ 2 Debug: 3/ 3 – 3/ 3 List of issue # and dates: Issue 3: January 9, 2008 Issue 3: January 10, 2008 Issue 3: January 11, 2008 January 11, 2008 ------------------------ In short, while now the value of \getnumber[IssueNumber] is correct before and after, its value in \placelistofissues is always the last value, i.e. equal to the total number of issues. And this does NOT even change, when one replaces Issue~\getnumber[IssueNumber]: Issue~\IssueCounter: in \TempIssueText So for some reason, \TempIssueText is called twice ? How? Where? Unfortunately, my ConTeXt.foo is not yet good enough to make it over the TeX.bar here as I haven't found a way to make this work (preferably with \IssueCounter as all this \XXXnumber stuff does not seem to work the way I think it should, anyway...) And yes, ANY help with this is very welcome by now Sincerely Carsten P.S: Context version is 2007.01.12 15:56 / TeXlive / OS X

Have you looked at enumerations? They provide a way to something very similar to what you want.
If one places \NewIssue[Some Time] somewhere in the text, it should result in a new (issue / timestamp) to be generated, which can then placed in a list of issues / changes.
\defineenuemration[Issue][title=yes] \Issue[one]{January 9, 2008} blah blah blah \Issue[two]{January 10, 2008} more blah blah blah In issue \in[one] we wrote what we did on \about[one]
I also want to be able to make use of the last value Issue to be placed in the header, same goes for the last timestamp
Another option may to think of issue as a section (or subsection) \definehead[Issue][section] \Issue {Jan 9, 2008} What we did at that time. \Issue {Jan 10, 2008} something else \stoptext Then you can use \setupheadertexts[issue] to get the current issue in the header.
Now this is how I went out to do this in ConTeXt (maybe wrongly so?) following the manual and some examples on contextwiki
I haven't looked at your code below. First check if one the in-built stuctural environments of ConTeXt do what you want. Aditya

Hi Aditya, thanks for taking the time to answer this. And yes, I looked at what ConTeXt has already built in. On 12.01.2008 at 18:44 wrote Aditya Mahajan:

As a matter of fact, I am using the following for all the heavy stuff (implementing that in LaTeX is/was a REAL pain) \definesynonyms[Issue][issues][\IssueText][\IssueDate] \setupsynonyms[Issue][criterium=all] \Issue[1]{Issue 1:}{Some Date} \Issue[2]{Issue 2:}{\currentdate} and if I just put the values in by hand, it works like a champ. Sorted list and all. ;-D Took me less than 5 minutes to implement (read: find in the manual). Just gonna _love_ ConTeXt for that! Now, with such a nice success (and because I have much more "counter" stuff on the way) I was feeling lucky ... and spent the next 5 hours figuring out / searching on the web / going over the source how to have the "number" for each issue placed automatically, every time a new issue date is set. Yes, sure, I could just _write_ that in, but then I would have to check myself, which number is exactly the one I need, and not have the computer do it for me. But, hey where is the fun in that? ;-) What this all burns down is, that I /really/ would like to understand, how I can pass a value from a counter as (constant) argument to a self- defined function. As that seems to be the core of the matter/problem here. Any suggestions? Cheers Carsten

You need to understand how synonyms work. It writes enteries to the tuo file, and then uses that in the second pass to sort things. One way to make sure that you have the correct entry in the tuo file is to use expanded: \definesynonyms[Issue][issues][\IssueText][\IssueDate] \setupsynonyms[Issue][criterium=all] \newcounter\IssueCounter \def\NewIssue{\dosingleargument\doNewIssue} \def\doNewIssue[#1]% {\increment\IssueCounter %Debug: \IssueCounter / \getnumber[IssueNumber]% \doifelsenothing{#1} {\expanded{\Issue[\IssueCounter]{\IssueCounter}{\currentdate}}} {\expanded{\Issue[\IssueCounter]{\IssueCounter}{#1}}}} % Compare the tuo file with and without expanded and you will know what is % happening. \starttext \NewIssue[January 9, 2008] \NewIssue[January 10, 2008] \NewIssue % January 11, 2008 List of issue \# and dates: \placelistofissues \blank \IssueDate{\IssueCounter} % produces correct result in either case \stoptext Aditya
Hi Aditya, yes, looking at the .tuo did the trick. :-D I had tried things with expanded already, but at that time I still had
{\expanded{\Issue[\IssueCounter]{Issue~\IssueCounter:}{\currentdate}}} as command. Which does NOT work (due to the tilde ~ resulting in an error message then) The rest was actually fine. Now, without it (i.e. "~") it works! ... {\expanded{\Issue[\IssueCounter]{Issue: \IssueCounter:}{\currentdate}}} ...
Thanks a lot, that had me seriously baffled ;-) Carsten On 12.01.2008 at 23:29 wrote Aditya Mahajan:

\nonbreakablespace works instead of ~. Aditya
