Using command line values in a TeX document; writing a script?

Using command line values in a TeX document; writing a script?

[Gerben Wierda]

[-- Attachment #1.1: Type: text/plain, Size: 1248 bytes --]

Currently, I process a file like this:

mtxrun --autogenerate --script context test12.tex

and in the file test12.tex one sees something like this:

\input archimate-mp
\ctxlua{moduledata.archimate(“myarchimatefile.xml")}

The latter parses the xml file and produces a PDF using generated MP code.

What I would like to do is not have to edit the .tex file when I want to process another .xml file but just pass the name of the xml file on the command line. And I would like to pass on a second filename with some local overrides settings fr my code. All of this needs to be data that I can use in my programming. E.g. something like:

mtxrun --autogenerate --script myscriptname “ myarchimatefile.xml” “myhelper.xml"

It is OK that this would produce a fixed name output file (e.g. myparsedxml.pdf), so it is OK to have some generic myparsedxml.tex (instead of test12.tex as per my example) file that produces a .pdf and more in the current working directory but resides somewhere in a generic place. But preferably, this would produce myarchimatefile.pdf

I’ve read the manual on mtxrun scripts to see if I can make my own, but I’m utterly failing to understand what is written in a way that let me write my own.

Hi Gerben,

What you want is quite easy to do since you are using lua already. Try this:

  % context --whatever=green test

with test.tex:

  \starttext
  \startluacode
  table.print(environment.arguments)
  \stopluacode
  \stoptext

everything from the command line ends up in environment.arguments.

Best wishes,
Taco

This helps for adding information to my processing. 

What I was also looking for is that I don’t have a test.tex anymore, just the XML file I am parsing and a command line action.

So, I use mtxrun, give it the name of an XML. lua code (using a ’script’ somewhere?) reads the XML, extracts a name (e.g. ‘foo’) from it, creates a .tex file (e.g. ‘foo.tex’), produces a .pdf file from that .tex file (e.g. ‘foo.pdf').

When processing XML, I normally use 
  
   context —environment=whatever.tex file.xml

with whatever.tex being a mix of tex and lua to setup and process the XML directly,
perhaps including other XML files as needed.

But when you need to extract stuff and rename files, a Makefile or shell script
comes more naturally (at least for me).

But this means that the whatever.tex file needs to exist beforehand and the result is whatever.pdf

I want the actual PDF to be produced have a name that comes from the XML I am processing and thus the whatever.tex file be created by lua. There is no whatever.tex file before I run the command.

Pre-command:
	XML:
		contains file name “foo”
	there is no .tex file

Command:
	produces foo.tex (gets the name from the XML) and “foo.pdf"

The TeX file in Tacos example contains the xmlsetup entries which are used
to map the XML tags to ConTeXt commands and environment, the resulting
PDF file has the same name as the XML file.

That is different from

	 the resulting PDF file has the name of an entry/field in the XML file.

So, what I am looking for is:

	command foo.xml

which results in 

	bar.pdf

where ‘bar’ is text in foo.xml

Gerben,

I do not know if it is possible with Context. 

But this definitely works with an xsl operation. 

You will need an xsl file like this:

myxslfile.xsl:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:template match="contacts">
  <xsl:for-each-group select="contact" group-by=“contact/@ad">
    <xsl:result-document href="groep-{current-grouping-key()}.xml">
       <contacts>
         <xsl:copy-of select="current-group()"/>
       </contacts>
    </xsl:result-document>
  </xsl:for-each-group>
</xsl:template>
<!-- alleen met Saxon, xslt: versie 2 -->

</xsl:stylesheet>


myxmlfile.xml

<contacts>
<contact>
<name ad=“BAR">John</name>
</contact>
<contact>
<name ad=“BAR”>Gerben</name>
</contact>
</contacts>

Use it like this with saxon (xsl version 2).

saxon -xsl:myxslfile.xsl -s:myxmlfile.xml -o:dummy.xml

This program will generate an empty dummyfile.xml but also xml files, (e.g. BAR.xml) in which it will collect al contact that have @ad=‘BAR', and there will be as many files as you have different values of @ad in your xml file. I am very far from being a specalist on xsl, please refer for further information to xsl forums. Have fun experimenting!

I do this myself and then have a script generate the pdfs.

Hope this helps.

Robert
