:: String -> Int is:exact -package:base -package:ViennaRNAParser -package:locators -package:monads-tf -package:Cabal -package:filepath -package:hxt -package:safe
Returns the display width of a string. Assumes all characters with
unknown widths are 0 width.
Like strWidth, but also strips ANSI escape sequences before
calculating the width.
This is no longer used in code, as widths are calculated before adding
ANSI escape sequences, but is being kept around for now.
Returns the precedence of default Haskell operators
Get the hash of a string.
This util is currently used to generate an
Int used for the
internal pattern variable representation from the external pattern
variable representation (
String)
The error used in
fixpointToFinal,
runFixpoint and
runFixpointM when the result of a failed computation is
recursively used and somehow visible. You may use this for your own
Fixpoint interpreters. The argument should be the name of the
interpreter.
Alias for errorWithoutStackTrace (for base >= 4.9)
