unescaping-print: Tiny package providing unescaping versions of show and print

[ bsd3, library, text ] [ Propose Tags ] [ Report a vulnerability ]

This package solves the problem of escaping all "non-printable" symbols by the standard show function. It provides the ushow and uprint functions which replace show and print from Prelude. The function uprint is intended to be used as custom printing function in GHCi (with the `-interactive-print` option).

Readme for unescaping-print-0.1

[back to package description]

This package provides the replacement for the show and print functions which escape "non-printable" characters including every character with the ASCII code greater than 127. It is intended to be used with GHCi's -interactive-print option:

GHCi> :set -interactive-print=UnescapingPrint.uprint
GHCi> "Съешь ещё этих мягких французских булок, да выпей чаю"
"Съешь ещё этих мягких французских булок, да выпей чаю"
GHCi> "Vogt Nyx: »Büß du ja zwölf Qirsch, Kämpe!«"
"Vogt Nyx: »Büß du ja zwölf Qirsch, Kämpe!«"
GHCi> "Dès Noël où un zéphyr haï me vêt de glaçons würmiens je dîne d’exquis rôtis de bœuf au kir à l’aÿ d’âge mûr & cætera"
"Dès Noël où un zéphyr haï me vêt de glaçons würmiens je dîne d’exquis rôtis de bœuf au kir à l’aÿ d’âge mûr & cætera"

This approach works for (almost) any type with Show instance:

GHCi> (Just "Привет, ", 'м','и','р') 
(Just "Привет, ",'м','и','р')

This change could be made persistent via $HOME/.ghci file.
