:: String -> Int -package:hledger-lib -package:speculate -package:express -package:safe -package:Cabal -package:polysemy -package:ghc -package:dbus -package:hxt -package:simple-cmd -package:hegg

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.
Alias for realLength.
Given a number encoded in Locator16, convert it back to an integer.
Raises an error with a printf-specific prefix on the message string.
Like the function error, but appends a stack trace to the error message if one is available.
Raises a SizeOverflowException, with a message using the given function name.
raise a fatal internal error; message may have multiple lines
stop execution and displays an error message
Same as error but will make HDL generation fail if included in the final circuit. This is useful for the error case of static assertions. Note that the error message needs to be a literal, and during HDL generation the error message does not include a stack trace, so it had better be descriptive.
