Description
This module contains functions for cleaning up types before they are rendered, e.g. in error messages or annoations, and also some PPrint instances that rely upon tidying.
Synopsis
- tidySpecType :: Tidy -> SpecType -> SpecType
- tidySymbol :: Symbol -> Symbol
- panicError :: Error -> a
- class Result a where
- errorToUserError :: Error -> UserError
- cinfoError :: Cinfo -> Error
Tidying functions
tidySymbol :: Symbol -> Symbol #
tidySymbol is used to prettify the names of parameters of kvars appearing in solutions.(*)
For example, if you have a kvar $k0 with two parameters, you may have a solution that looks like
0 < lq_karg$nnf_arg$##k0
where we know it is a kvar-arg because of the
- kArgPrefix (lq_arg)
- hvarArgPrefix (nnf_arg)
- k0 the name of the kvar
- `0` the parameter index
- k0 again (IDK why?!)
all of which are separated by ##
So tidySymbol tests if indeed it is a kArgPrefix-ed symbol and if so converts
`lq_karg$nnf_arg$##k0` ----> `$k0##0`
Panic and Exit
panicError :: Error -> a Source #
This function is put in this module as it depends on the Exception instance, which depends on the PPrint instance, which depends on tidySpecType.
Show an Error, then crash
