I'm too studpid for Context...

I believe, it is possible to use in Conext the otf-fonts I have in my computer. I generated the database, the quert shows me, that the font is there, but I can not get it in my file. And when I read the chapter in the Manual or whatever I can find, I read a lot about Typescripts and unterstand absolutely nothing. I find how to make a typescript for palatino, which makes no difference, but I don’t unterstand why I shall make a typescript and how. Is there a text which tells step by step what I have to so and why? Now the situation is: I have a lot of Fonts and can use just four. That was much easier with LaTeX...

Re: [NTG-context] Simple command with variable number of arguments

Dear Hans, Here is the file in my desktop. The reason I didn’t define “sgn” in the function “uppertri” is that it is inherited from the call of “determinant’. However, I put “sgn=1” so that the function “uppertri” works independently. I checked the function “uppertri” and found that it worked fine. Here is a sample file. \environment MatrixLuacode \starttext \getbuffer[luaMatrix] \startformula\startalign \startluacode local mat = {{0, 2, 4, -4, 1},{0, 0, 2, 3 , 4}, {2, 2, -6, 2, 4 }, {2,0 , -6, 9, 7},{2, 2, -6, 2, 4 },{2, 2, -6, 2, 4 }} -- local mat = {{1,2,3},{3,4,5},{3,4,5},{3,4,5},{3,4,5}} context.NC("\\text{Given Matrix}\\quad\\Rightarrow\\quad") context.NC() matrixOP.write(mat) context.NR() context.NC() context("\\text{Upper Triangular}\\quad\\Rightarrow\\quad") mat = matrixOP.upperTri(mat) context.NC() matrixOP.write(mat) context.NR() \stopluacode \stopalign\stopformula \stoptext Sometimes, I got “-0” as an entry of matrix after calculation but I couldn’t resolve it(I asked about it to this list before). Thank you. Best regards, Dalyoung

Dear Hans, Thank you for checking and enhancing. I also got an error at “uppertri” as you point out. The version that I have sent is one in my notebook which may be different from that in the desktop at school. When I made a class material, it worked fine. I have to check it and send it to you again. I appreciate you for making it more usable for ConTeXt users. I also found that there is a matrix module for lua programming. It is nice for the calculation of matrix, but I have a difficulty to typeset the result. That’s why I try to write a code even though I am not good in Lua programming. If it is easy to take over the result into TeX, using the lua module is much efficient and correct, I think. Anyway, I hope that it helps to typeset matrices. Best regards, Dalyoung > Hi, > > Can you check the attached? The uppertri is wrong but it was already wrong (e.g. sign is used but never assigned). I inlined some code so ... I think there were some more errors (obscured by the fact that that piece of code is not reached). > > We can turn this into m-matrix or so, maybe we need to add some more. > > Hans > > ----------------------------------------------------------------- > Hans Hagen | PRAGMA ADE > Ridderstraat 27 | 8061 GH Hasselt | The Netherlands > tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com > | www.pragma-pod.nl > ----------------------------------------------------------------- > <xtest.tex>

[***SPAM***] texi2pdf
by hwitloc＠gmail.com 23 May '14

23 May '14

I have installed the standalone and it works well on my Xubuntu system. I tried to run texi2pdf, which not a part of the standalone system, but fails due to: "...don't have any working TeX binary installed.." If the standalone has one I will add its path to my PATH and the texi2pdf should work. I'm trying to avoid installing a full TeXLive distribution on this old limited memory machine. Any advice would help. Thenks

LuaTeX/ConTeXt connect to SQL Server
by Matt Baker 23 May '14

23 May '14

FROM MY POSTING AT: http://tex.stackexchange.com/questions/180018/luatex-context-connect-to-sql… I am looking to connect ConTeXt to a SQL Server database. I have looked through the manuals, and even read pragma-ade's SQL PDF (which, for me, seems a bit abstract). I am not extremely familiar with Lua but have read up on the language (I am more familiar with JS). For LaTex I used nlatexdb which did the trick, but LaTex isn't able to do what ConTeXt can. - The connection needs to use Windows Authentication. - The document is set up as a letter with an environment that it pulls from. - It would be preferable to have the connection and queries be seperate from the letter itself, and be able to place variables into the letter that can be populated through the queries (much like nlatexdb) if possible. - example: Dear ??first ??last, Thank you for your interest in ??product... etc. I am rather new to ConText and just starting to get the hang of it, long time latex user, the transition starts off rather confusing, but once it makes sense it opens up a whole toolbox of available tools which is great. Just need this one last tool. Any help would be much appreciated. EDIT:: Honestly I haven't gotten to any point that I felt I could attempt trying the connection. Looking at the SQL PDF from pragma-ade it should look something like: local presets = { server = "XXX\XXX", Database = "Customer", Integrated Security = "True", } presets.id = "XXX" local template = [[ SELECT 'Control_Content' FROM 'Customer.dbo.Report_Client_Data' WHERE 'Control_Name' LIKE 'Long_Name' AND 'Client_Id' = 154; ]] local data, keys = utilities.sql.execute { presets = presets, template = template, variables = {}, } I can't seem to find where or how the connection is being made, except perhaps where utilities.sql.execute is called, but I can't find any information anywhere about such a call in lua or context...

Dear Luigi and listers, Last year, I need to write a text for a linear algebra class. Since there are many \startmatrix … \stopmatrix and matrix calculations, I wrote a lua code which did matrix calculations and writing with a lot of help from this list. Using the code, I can write class materials easily. It is good enough for my purpose. I am not good in Lua coding, so there may be many things to be checked for efficiency and for stability. However, I attached the code because there may be someone who need it. It is also good thing to return what I get from the list back. I hope that you enhance the code for better performance since you are an expert in Lua. I always thank to this list and to developers of ConTeXt.

Experience with DITA XML or XSL/FO
by Mica Semrick 23 May '14

23 May '14

Hi list, I've been contemplating making a ConTeXt output or parser for DITA XML and was wondering if anyone has worked with DITA and ConTeXt before? If you have and could offer any advice and/code, that would be most helpful! Best, Mica

[OT] Twenty Questions for DEK

Bold small caps
by Mojca Miklavec 23 May '14

23 May '14

Hi, I always forget how to use bold or italic small caps (I keep mixing addff/setff and smcp/+smcp/smallcaps etc.). In ideal world it could be nice if simply {\sc Normal and \bf Bold Small Caps} or {\bf\sc Bold Small Caps} would work out-of-the-box. The first hit on the wiki was http://wiki.contextgarden.net/Bold_small_caps which contained just the MKII example. I added a MKIV example {\setff{smallcaps} Normal and \bf bold Small Caps.} but the problem is that this example only works with <put any font name here> except for the default Latin Modern setup. Would it make sense to fix this for the default LM setup as well? Mojca
