ScriptsGen

The script is aiming for a handy tool when you need to test your algorithm with different combinations of parameters. It helps to generate a script file for each parameter combination according to a template file, which is particularly suitable for subsequent parallel running.

Usage

$ scripts_gen.py --help
usage: scripts_gen.py [-h] --template FILE --save-to FOLDER --param DICT
                      --format STRING [--open TOKEN] [--close TOKEN]
                      [--comment TOKEN] [--delete]

Generate scripts from a template, by enumerating combinations of parameters.

arguments:
  -h, --help        show this help message and exit
  --template FILE   The location of the template file.
  --save-to FOLDER  The destination folder for the scripts.
  --param DICT      All the parameters with their values as a dictionary,
                    where a value can be a list, or a file name that refers to
                    a file containing one parameter value per line. See
                    Python's dictionary literals
                    (http://docs.python.org/3/reference/expressions.html
                    #dictionary-displays).
  --format STRING   The format string for the file names of the scripts. See
                    Python's format string syntax
                    (http://docs.python.org/3/library/string.html#format-
                    string-syntax).
  --open TOKEN      The token that indicates the start of a template
                    identifier. (default: <%)
  --close TOKEN     The token that indicates the end of a template identifier.
                    (default: %>)
  --comment TOKEN   The token placed in the template file that treats the rest
                    of the line, which will be removed in the scripts, as a
                    comment. (default: ###)
  --delete          Delete the contents in the destination folder before
                    creation. (default: False)

Also, there are some built-in template identifiers for the components of the script names (see example/template.txt):

• __FULL_PATH__ : the full path of the current script
• __DST_FOLDER__ : the destination folder of this run, no trailing '/' or '\\'
• __FILE__ : the file name of the current script
• __FILE_NO_EXT__ : the file name of the current script but without extension
• __EXT__ : the extension of the current script

In a word,

<%__FULL_PATH__%> == <%__DST_FOLDER__%>/<%__FILE__%> == <%__DST_FOLDER__%>/<%__FILE_NO_EXT__%>.<%__EXT__%>
