Installing

You need to install markdown

python -m pip install markdown

Description

Descriptions may use markdown. Check its syntax here!
You may use moopec.py to read one or more files in the DSL and generate the problem
The examples folder has some examples
Please feel free to install feedback.tcl on ~mooshak/packages/utils/ to have a nice feedback (courtesy of Pedro Ribeiro)
After generating the folders containing the problems, simply copy them to ~mooshak/data/contests/YOUR_CONTEST/problems

DSL description

NAME The name of the problem
LETTER This is the name of the folder that stores the problems and what is stored in letter
TESTS One or more tests; it ends with an END keyword
- INPUT One line of input
- LONGINPUT One or more lines of input; it ends with an END keyword
- INPUTGEN An optional integer followed by a function (either a lambda function or the name of a function in an imported module)
- FEEDBACK A feedback message for all inputs. If the message is Description, these tests will be automatically added to the end of the description
- POINTS How many points to award to each of the inputs
- SHOW if present, it shows these tests to the user
IMPORT The name of a module to import
CODE One or more lines, ending with an END keyword. This creates a module and adds the code into it.
SOLVER A Function that will be used to create the output for each test. This may either be a lambda function or the name of a function in an imported module. It takes the input.
EXPLANATION A function that will be used for generating an explanation for each test that is shown in the problem description. This may either be a lambda function or the name of a function in an imported module. It takes the input.
DESCRIPTION One or more lines, using the markdown syntax, ended with the END keyword
INPUT_TRANSF a function (either a lambda function or the name of a function in an imported module) that will be used to transform the inputs. This transformation is the last step before creating the input files.
POINTS Evenly distributes this number of points to all tests

A file may have several problems, the first keyword being NAME and finished by END.
