#
# January 2015
# unified all setups by passing the script on the cl rather than via a PIPE - no need for treat_bash_special so removed
#
# in the process of building a complex tool
# added ability to choose one of the current toolshed package_r or package_perl or package_python dependencies and source that package
# add that package to tool_dependencies
# Note that once the generated tool is loaded, it will have that package's env.sh loaded automagically so there is no
# --envshpath in the parameters for the generated tool and it uses the system one which will be first on the adjusted path.
#
# sept 2014 added additional params from
# https://bitbucket.org/mvdbeek/dockertoolfactory/src/d4863bcf7b521532c7e8c61b6333840ba5393f73/DockerToolFactory.py?at=default
# passing them is complex
# and they are restricted to NOT contain commas or double quotes to ensure that they can be safely passed together on 
# the toolfactory command line as a comma delimited double quoted string for parsing and passing to the script
# see examples on this tool form

# august 2014

# Allows arbitrary number of input files
# NOTE positional parameters are now passed to script
# and output (may be "None") is *before* arbitrary number of inputs
#
# march 2014
# had to remove dependencies because cross toolshed dependencies are not possible - can't pre-specify a toolshed url for graphicsmagick and ghostscript
# grrrrr - night before a demo
# added dependencies to a tool_dependencies.xml if html page generated so generated tool is properly portable
#
# added ghostscript and graphicsmagick as dependencies 
# fixed a wierd problem where gs was trying to use the new_files_path from universe (database/tmp) as ./database/tmp
# errors ensued
#
# august 2013
# found a problem with GS if $TMP or $TEMP missing - now inject /tmp and warn
#
# july 2013
# added ability to combine images and individual log files into html output
# just make sure there's a log file foo.log and it will be output
# together with all images named like "foo_*.pdf
# otherwise old format for html
#
# January 2013
# problem pointed out by Carlos Borroto
# added escaping for <>$ - thought I did that ages ago...
#
# August 11 2012 
# changed to use shell=False and cl as a sequence

# This is a Galaxy tool factory for simple scripts in python, R or whatever ails ye.
# It also serves as the wrapper for the new tool.
# 
# you paste and run your script
# Only works for simple scripts that read one input from the history.
# Optionally can write one new history dataset,
# and optionally collect any number of outputs into links on an autogenerated HTML page.

# DO NOT install on a public or important site - please.

# installed generated tools are fine if the script is safe.
# They just run normally and their user cannot do anything unusually insecure
# but please, practice safe toolshed.
# Read the fucking code before you install any tool 
# especially this one

# After you get the script working on some test data, you can
# optionally generate a toolshed compatible gzip file
# containing your script safely wrapped as an ordinary Galaxy script in your local toolshed for
# safe and largely automated installation in a production Galaxy.

# If you opt for an HTML output, you get all the script outputs arranged
# as a single Html history item - all output files are linked, thumbnails for all the pdfs.
# Ugly but really inexpensive.
# 
# Patches appreciated please. 
#
#
# long route to June 2012 product
# Behold the awesome power of Galaxy and the toolshed with the tool factory to bind them
# derived from an integrated script model  
# called rgBaseScriptWrapper.py
# Note to the unwary:
#   This tool allows arbitrary scripting on your Galaxy as the Galaxy user
#   There is nothing stopping a malicious user doing whatever they choose
#   Extremely dangerous!!
#   Totally insecure. So, trusted users only
#
# preferred model is a developer using their throw away workstation instance - ie a private site.
# no real risk. The universe_wsgi.ini admin_users string is checked - only admin users are permitted to run this tool.
