I am maintaining a small vademecum for my workplace. One of the things it contains is a list of handy phone numbers, which should be sorted. Until now I have used the attached hack. It has worked reasonably well until the directory outgrew the one page. Before I start to modify my hack it occurred to me that ConTeXt most likely has a machinery for this already. It is a sort of register, after all. I have looked in the manual at registers and sorted lists but have not been able to find what I want. The desired specifications are: 1. columns (to save space) 2. sorted (in a correct Swedish order) 3. spans several pages Thanks for any pointers, Johan -- Johan Sandblom, MD PhD m +46735521477 Sweden "What is wanted is not the will to believe, but the will to find out, which is the exact opposite" - Bertrand Russell

Hello Johan. I wonder whether it would be better to have a list of telephone numbers in an external file (eg csv file) that can handle aplication such as Excel or Calc. The list is sorted by this instrument and ConTeXt would just typed data from external file. For practical reasons it would be better to have that list in an external file. I do these things with my scancsv.lua tool. Now I finishing module for ConTeXt. see http://public.hajtmar.com/?cesta=JRsVFQdsBhwIWyAGFFsAJkBJQURsAgsVByYcDREAKh0...

So if I understand correctly, everything is fine except that your current solution only works for a single page? If so, replacing \bTABLE with \bTABLE[split=yes] should do the trick. (Sorry, don't have time to test this now, but it is documented at http://wiki.contextgarden.net/TABLE .) Hope this helps, Pont

Thank you for your suggestions! Jaroslav, having the numbers in a separate file and sorting there, while possible, would increase overhead in managing the document and make it impossible to enter phone numbers at other places in the text. Pontus, splitting the table over pages would interact poorly with columns since the first entry on the second page would be the one after the last in the first column on the first page: 1 6 11 2 7 12 3 8 13 4 9 14 5 10 15 Wolfgang, this is what I was hoping for, but there are some problems: - the numbers should be flush right - in the real file entries are longer than in my example file, but none so long as to require a line break. Here many entries require a line break and the next entry runs over the second line of the broken entry. See a slightly more realistic example below.

Again, it is your decision, and of course we don't know what special requirements you have, but using some sort of well-known format would make your solution much more future-proof. Good luck Thomas

I agree there may be advantages with a solution involving an external file. The phone directory is slowly growing, but it has taken it years to reach one page, so I am not sure the size of the database will ever be a problem. The current solution works for now, but it is good to be able to handle external files this way if the need arises. Thank you for your opinions. Johan 2011/8/3 Jaroslav Hajtmar :

Hello Johan, Certainly it is possible to combine solution of Wolfgang with retrieving data from an external file without having to sort the data by another application. Enough to define a simple ConTeXt macro that contains a piece of Lua code. Here my modification of Wolfgang last solution for your inspiration:

\def\processexternalfile#1{ \startluacode myextfile=io.open('#1',"r") repeat line=myextfile:read() if line ~= nil then splitline=string.split(line, ",") context('\\Telefon['..splitline[1]..']{'..splitline[2]..'}') end until (line == nil) myextfile:close() \stopluacode }

\mainlanguage[swedish]

\definedescription [TelefonEntry] [width=2em]

\unexpanded\def\TelefonCommand#1#2#3% {\hbox to \hsize{#2\hfil#3}\par}

\definesorting[Telefon][Telefone]

\starttext

Wolfgang's solution:

\Telefon[Eldallah Awdawebi]{78423} \Telefon[Nada Pipidepaulou]{78264} \Telefon[Aölaksd aölksd]{044578264} \Telefon[Ö]{320399} \Telefon[å]{23402394} \Telefon[åå]{23042} \Telefon[ååå]{098234}

\startcolumns[n=3] \placelistofsorts[Telefon][criterium=all,command=\TelefonCommand] \stopcolumns

\blank[big]

% Create external CSV file "extfile.csv". % Structure of this file is:

% Eldallah Awdawebi,78423 % Nada Pipidepaulou,78264 % Aölaksd aölksd,044578264 % Ö,320399 % å,23402394 % åå,23042 % ååå,098234

My solution - processing an external file \quotation{extfile.csv}:

\processexternalfile{extfile.csv}

\startcolumns[n=3] \placelistofsorts[Telefon][criterium=all,command=\TelefonCommand] \stopcolumns

\stoptext

Best regards Jaroslav

Thank you for your suggestions!

Jaroslav, having the numbers in a separate file and sorting there, while possible, would increase overhead in managing the document and make it impossible to enter phone numbers at other places in the text.

Ultimately, it is of course your decision what you want to do, but I think you were a bit quick to reject Jaroslav's suggestion. TeX isn't meant to store databases. Having the information in some external file will actually make things much easier in the middle and long run. It's easier to manage, it scales better, and it will allow you to reuse this information in other ways. And ConTeXt is excellent in that it can handle many different input formats. I wrote something about using databases in xml or sql format in the latest MAPS issue; csv is easy to produce (libreoffice calc can produce csv). You could even store the information in a raw lua table and then retrieve it via some macros. I think the sorting itself should be done in ConTeXt because language support for the other solutions is probably not as straightforward (if it exists at all), but I would definitely store the information in some other format. Again, it is your decision, and of course we don't know what special requirements you have, but using some sort of well-known format would make your solution much more future-proof.

Good luck

Thomas
