10 # This is a Galaxy tool factory for simple scripts in python, R or whatever ails ye.
|
|
|
11 # It also serves as the wrapper for the new tool.
|
|
|
12 #
|
|
|
13 # you paste and run your script
|
|
|
14 # Only works for simple scripts that read one input from the history.
|
|
|
15 # Optionally can write one new history dataset,
|
|
|
16 # and optionally collect any number of outputs into links on an autogenerated HTML page.
|
|
|
17
|
|
|
18 # DO NOT install on a public or important site - please.
|
|
|
19
|
|
|
20 # installed generated tools are fine if the script is safe.
|
|
|
21 # They just run normally and their user cannot do anything unusually insecure
|
|
|
22 # but please, practice safe toolshed.
|
|
|
23 # Read the fucking code before you install any tool
|
|
|
24 # especially this one
|
|
|
25
|
|
|
26 # After you get the script working on some test data, you can
|
|
|
27 # optionally generate a toolshed compatible gzip file
|
|
|
28 # containing your script safely wrapped as an ordinary Galaxy script in your local toolshed for
|
|
|
29 # safe and largely automated installation in a production Galaxy.
|
|
|
30
|
|
|
31 # If you opt for an HTML output, you get all the script outputs arranged
|
|
|
32 # as a single Html history item - all output files are linked, thumbnails for all the pdfs.
|
|
|
33 # Ugly but really inexpensive.
|
|
|
34 #
|
|
|
35 # Patches appreciated please.

|
|
|
40 # derived from an integrated script model
|
|
|
41 # called rgBaseScriptWrapper.py
|
|
|
42 # Note to the unwary:
|
|
|
43 # This tool allows arbitrary scripting on your Galaxy as the Galaxy user
|
|
|
44 # There is nothing stopping a malicious user doing whatever they choose
|
|
|
45 # Extremely dangerous!!
|
|
|
46 # Totally insecure. So, trusted users only
|
|
|
47 #
|
|
|
48 # preferred model is a developer using their throw away workstation instance - ie a private site.
|
|
|
49 # no real risk. The universe_wsgi.ini admin_users string is checked - only admin users are permitted to run this tool.
