**Details and attribution** 
(see GTF_)

**Local Admins ONLY** 
Only users whose IDs found in the local admin_user configuration setting in universe_wsgi.ini can run this tool.

**If you find a bug** 
Please raise an issue at the bitbucket repository GTFI_

**What it does** 
This tool enables a user to paste and submit an arbitrary R/python/perl script to Galaxy passing
any number of input files and their metadata names to the script for use in (eg) summaries or reports.
This allows quick generation of tools capable of taking some arbitrary number of user selected inputs
for the "reduce" step of a map-reduce HPC model.

**Input options** 
This version allows multiple input file selected from the history - their paths and metadata names
are provided to your script - see the examples below for each scripting language. Python uses argparse.
Rscript uses some code to create all the command line variables. Parameters are injected into the bash/sh
execution environment so they magically "appear" as $ prefixed variables and will also be found on the
command line as parameters to be parsed if that's your preference.
Note that additional parameters are NOT presented to the user of the generated tool but are frozen with the script.
If there's demand, it would not be too hard to add them to the generated script...

**Output options** 
Optional script outputs include one single new history tabular file and for scripts that create multiple file reports
or analyses, an Html page linking every file and image created by the script can be automatically generated.

**Tool Generation option** 
Once the script is working with test data, this tool will optionally generate a new Galaxy tool in a Tool Shed (gzip) repository file
ready to upload to your local toolshed for sharing and installation.
Provide a small sample input when you run generate the tool because it will become the input for the generated functional test.

.. class:: warningmark

**Note to system administrators** 
This tool offers *NO* built in protection against malicious scripts. It should only be installed on private/personnal Galaxy instances.
Admin_users will have the power to do anything they want as the Galaxy user if you install this tool.

.. class:: warningmark

**Use on public servers**  is STRONGLY discouraged for obvious reasons

The tools generated by this tool will run just as securely as any other normal installed Galaxy tool but like any other new tools, should always be checked carefully before installation.
We recommend that you follow the good code hygiene practices associated with safe toolshed.

**Scripting conventions** The pasted script will be executed with the path to the (optional) input tabular data file path or NONE if you do not select one, and the path to the optional
output file or None if none is wanted, as the first and second command line parameters. The script must deal appropriately with these - see Rscript examples below.
Note that if an optional HTML output is selected, all the output files created by the script will be nicely presented as links, with pdf images linked as thumbnails in that output.
This can be handy for complex scripts creating lots of output.

<![CDATA[

**Multiple inputs**

Your script will receive up to 3 named parameters
INPATHS is a comma separated list of input file paths
INNAMES is a comma separated list of input file names in the same order
OUTPATH is optional if a file is being generated, your script should write there
Your script should open and write files in the provided working directory if you are using the Html
automatic presentation option.

Python script command lines will have --INPATHS and --additional_arguments etc. to make it easy to use argparse

Rscript will need to use commandArgs(TRUE) - see the example below - additional arguments will
appear as themselves - eg foo="bar" will mean that foo is defined as "bar" for the script.

Bash and sh will see any additional parameters on their command lines and the 3 named parameters
in their environment magically - well, using env on the CL

***python***::

 # argparse for 3 possible comma separated lists
 # additional parameters need to be parsed !
 # then echo parameters to the output file
 import sys
 import argparse
 argp=argparse.ArgumentParser()
 argp.add_argument('--INNAMES',default=None)
 argp.add_argument('--INPATHS',default=None)
 argp.add_argument('--OUTPATH',default=None)
 argp.add_argument('--additional_parameters',default=[],action="append")
 argp.add_argument('otherargs', nargs=argparse.REMAINDER)
 args = argp.parse_args()
 f= open(args.OUTPATH,'w')
 s = '### args=%s\n' % str(args)
 f.write(s)
 s = 'sys.argv=%s\n' % sys.argv
 f.write(s) 
 f.close()



***Rscript***::

 # tool factory Rscript parser suggested by Forester
 # http://www.r-bloggers.com/including-arguments-in-r-cmd-batch-mode/
 # additional parameters will appear in the ls() below - they are available
 # to your script
 # echo parameters to the output file
 ourargs = commandArgs(TRUE)
 if(length(ourargs)==0){
    print("No arguments supplied.")
 }else{
    for(i in 1:length(ourargs)){
         eval(parse(text=ourargs[[i]]))
    }
 sink(OUTPATH)
 cat('INPATHS=',INPATHS,'\n')
 cat('INNAMES=',INNAMES,'\n')
 cat('OUTPATH=',OUTPATH,'\n')
 x=ls()
 cat('all objects=',x,'\n')
 sink()
 }
 sessionInfo()
 print.noquote(date())


***bash/sh***::

 # tool factory sets up these environmental variables
 # this example writes those to the output file
 # additional params appear on command line
 if [ ! -f "$OUTPATH" ] ; then
    touch "$OUTPATH"
 fi
 echo "INPATHS=$INPATHS" >> "$OUTPATH"
 echo "INNAMES=$INNAMES" >> "$OUTPATH"
 echo "OUTPATH=$OUTPATH" >> "$OUTPATH"
 echo "CL=$@" >> "$OUTPATH"

***perl***::

 (my $INPATHS,my $INNAMES,my $OUTPATH ) = @ARGV;
 open(my $fh, '>', $OUTPATH) or die "Could not open file '$OUTPATH' $!";
 print $fh "INPATHS=$INPATHS\n INNAMES=$INNAMES\n OUTPATH=$OUTPATH\n";
 close $fh;
