Documentation
olderThan :: FortranVersion -> String -> FortranVersion -> a -> a Source #
Continue only if the given version is equal to or older than a "maximum" version, or emit a runtime error.
continueOnlyFor :: [FortranVersion] -> String -> FortranVersion -> a -> a Source #
Continue if the given version is one of the given "permitted" versions, else emit a runtime error.
tooOld :: FortranVersion -> String -> FortranVersion -> a Source #
Emit a runtime error due to bad pretty printing.
Intended to be used in the otherwise guard.
printIndentedBlockWithPre :: FortranVersion -> Indentation -> Doc -> [Block a] -> Doc Source #
type Indentation = Maybe Int Source #
pprintAndRender :: IndentablePretty t => FortranVersion -> t -> Indentation -> String Source #
class IndentablePretty t where Source #

noParensLit :: FortranVersion -> Expression a -> Doc Source #
Pretty print an Expression inside parentheses, _except_ if the
Expression is an integer literal, in which case print without the parens.

| RefmtStNewline Int | Unsure yet whether current line it's a comment or statement. |
| RefmtStComment | Current line is a comment; no need to track column number. |

reformatMixedFormInsertContinuations :: String -> String Source #
Add continuations where required to a pretty-printed program.
Ensures that no non-comment line exceeds 72 columns.
The reformatting should be compatible with fixed and free-form Fortran
standards, so called intersection format. In this format the
last statement character should not be placed after column 72, however
continuation character should be put at column 73 (it should be ignored in
fixed-form language)
See: http://fortranwiki.org/fortran/show/Continuation+lines
This is a simple, delicate algorithm that must only be used on pretty printer output, due to relying on particular parser & pretty printer behaviour. In particular, comments not beginning a line (e.g. after a statement or continuation) won't be picked up as a comment, so could wreck that line. Be warned if you're using it on piles of funky-looking code!
prettyError :: String -> a Source #
error wrapper to make it easier to swap this out for a monad later.
