##Pollstr
Pollstr is a domain-specific language embedded in Haskell for specifying and generating surveys.
After running cabal install, run the tests by loading Examples/First.hs in
ghci and invoke the testLatex and testJSON functions. latexmk is required to build the pdf files from tex.
Things that have been updated:
-
Variable binding/environment management improvements: Variable mapping for responses and questions have been moved into the parser. It is now an error at parse time to reference an unbound variable or to use a duplicate name for both a question and a response. Variables of the same type can still be rebound, however.
-
More response types: In addition to single-selection, I've added a multiple-selection and a free response type. For multiple selection, the respondent may check all options that apply. For free response, space is provided for the respondent to write-in his response.
-
Addition skip options: For single-selection response types, users may now specify any number of (non-overlapping) skips. This is still rudimentary, and it would be nice to clean up the concrete syntax for this. Additionally, there is no check for overlapping options.
-
Tests have been added for the new features and grammar has been updated.
