How can I build an arara rule for running perl scripts

Question

I want to write an arara rule for perl scripts, especially for fancy-preview. (Another test-script: latexcount.)

---

Edit:

1. In the Command-Line perl fancy-preview jobname.tex works!

2. I have installed ActiveState Perl

---

This does not work

!config
# perl rule for arara
# version: 0.1
# requires arara 3.0+
identifier: perl
name: Perl
command: <arara> @{program} @{script} @{getBasename(file)} @{options}
arguments:
- identifier: program
  flag: <arara> @{parameters.program}
  default: cmd /c  perl
- identifier: script
  flag: <arara> @{parameters.script}
  default: fancy-preview
- identifier: options
  flag: <arara> @{parameters.options}
  default: --fancy_options="previewall,nosoap"

What can I do?

EDIT1:

The "rule" above is a first draft-version.

For the result, I thought about an inputpath: 'C:/MyPerlScripts/...' or so on - so I have not to build a coupled motion for my perl-scripts and could store them under a central place. But for this and others, the rule has to run ;) ...

---

EDIT2:

If I change

 - identifier: program
      flag: <arara> @{parameters.program}
      default: cmd /c start perl

there is no error-messgage but the perls scripts were not runned (ok, this only for Windows, but it does not work) - I do not understand! :(

---

Edit3:

Same effect as Edit2:

 - identifier: program
      flag: <arara> @{parameters.program}
      default: cmd /c start C:/Perl/bin/perl.exe

Same without 'start':

A litte message of partially success

I think the problem is partly the script fancy-preview and partly arara.

Because: If I use the script latexcount with "perl.yaml" as given above on the following document

% arara: perl: { script: latexcount.pl }

\documentclass{article}
\begin{document}
Count these words!
\end{document}

I get

Can't open --fancy_options=previewall,nosoap: No such file or directory at latexcount.pl line 72, <> line 8.

3 words in the main text
 in the footnotes
3 total

Status: SUCCESS

This is correct in each line!

I think (at fancy-preview etc.) arara stops, if there is a warning or something else. In that case, I do not know, what to do - this could be arara-interna or not? The authors-team are the last hope :()

Answer 1

So, I think, thats it:

· identifier program : please choose your own perl version here as default. In the most cases, artless "perl" is written here

· identifier inputfile: choose

% arara: perl: {script: xyz.pl , inputfile: '' }

for an empty value, for example in these cases, when the perl-script is not executed on a tex-file.

· boolean identifier onlylog gives the perl-log as perl_log.txt

% arara: perl: {script: xyz.pl , onlylog: yes }

Check (for Linux) if you need ^> perl_log.txt instead of > perl_log.txt

· identifier inputpath choose the path to the folder, which contains your perl-scripts ;)

· identifiers compile and options:

Example:

% HELP:
% Help-Info "fancy-preview":
% #arara: perl: { script: fancy-preview.pl , options: -h }

% Help-Info "perl":
% #arara: perl: { script: latexcount.pl , compile: -h }

perl.yaml

!config
# perl rule for arara
# version: 0.2a
# requires arara 3.0+, PERL
#
#  ### 
#  Please check defaults at 'program', 'inputpath' (and 'onlylog') !
#  ###
#
identifier: perl
name: Perl
command: <arara> @{program} @{compile} @{inputpath}@{script} @{inputfile} @{options} @{onlylog}
arguments:
- identifier: program
  flag: <arara> @{parameters.program}
  default: 'cmd /c c:\texlive\2013\tlpkg\tlperl\bin\perl.exe'  
#  default: <arara> @{ isWindows("cmd /c  perl", "perl") }
#  default: 'cmd /c  c:\Perl\bin\perl.exe'
- identifier: compile
  flag: <arara> @{parameters.compile}
- identifier: inputpath
  flag: <arara> @{parameters.inputpath}
  default: 'C:\Users\ccc\PerlScripts\'
- identifier: script
  flag: <arara> @{parameters.script}
- identifier: inputfile
  flag: <arara> @{parameters.inputfile}
  default: <arara> @{getBasename(file)}.tex
- identifier: options
  flag: <arara> @{parameters.options}
- identifier: onlylog
  flag: <arara> @{ isTrue( parameters.onlylog , "> perl_log.txt"  ) }

I tested with success: latexcount.pl and fancy-preview.pl (Warning: at fancy-preview.pl you have to do some preliminary work - pm-modules, acrotex-packages).

Example

% arara: perl: { script: latexcount.pl  }

\documentclass{article}
\begin{document}
Count these words, immediately! 
\end{document}
