Prelude.Spiros.Pretty

Description

Pretty-printing and Parsing, with standard casing/capitalization.

TODO separate packages?

simple-print-parse re-exports these packages:

  • simple-print;
  • simple-parse, which has more dependencies (like on the exceptions package).

Description

Provides utilities (and aliases) for defining simple ad-hoc parsers and (pretty-)printers for types (especially sum types).

Motivation

Useful when:

  • you want your program to print out a human-friendly representations of haskell types, or to be able to consume them in either a consistent format or a versatile format;
  • but, you don't want to be burdened by a dependency on some parser package.

(i.e. by "human-friendly", I mean "more pleasantly readable and writable than with Show / Read").

uses of Print include:

  • error messages.

uses of Parse include:

  • command-line options.

Features

Such "formats" include:

i.e. the user can define custom capitalization (via WordCasing) or a custom separator (via WordSeparator).

by default, each format's utility functions assume that:

  • constructors are written in (the conventional) class-case (i.e. ClassCase); and
  • the types are finite (satisfying Enum or GEnum).

but, each format's module also provides (more general) versions, which can be given:

  • some list of values; or,
  • even manually tokenized strings.

Examples

to print out a constructor, the default toPrinter function does the following:

  • show it;
  • break up the string shown in its words and/or subwords;
  • merge that list of strings (back into a single string) via some TokenStyle (by default, HyphenCase).

HyphenCase being the most readable, imo. it's most common token style for: command line options, URLs, and so on.

Naming

NOTE In this package, the word "print" means "convert to a human-friendly string", not "write to stdout".

Synopsis

Documentation

type Print a = a -> String Source #

Simple printer.

Usage:

Here is an example printer,

printVerbosity :: Parse Verbosity
printVerbosity = case

  Concise -> "concise"
  Verbose -> "verbose"

for this type

data Verbosity = Concise | Verbose

type Parse a = forall m. MonadThrow m => ParseM m a Source #

Simple parser.

Expansions.

                  Parse a

≡

(MonadThrow m) => ParseM m a

≡

(MonadThrow m) => (String -> m a)

Specializations.

Specializations include:

Parse a  ≡  (String -> Maybe                a)
Parse a  ≡  (String ->                      [a])
Parse a  ≡  (String -> Either SomeException a)
Parse a  ≡  (String -> IO                   a)

Usage:

Here is an example parser,

parseVerbosity :: Parse Verbosity
parseVerbosity s = go s

  where
  go = case
  
    "concise" -> return Concise
    "verbose" -> return Verbose
  
    "Concise" -> return Concise
    "Verbose" -> return Verbose
  
    "default" -> return def
  
    _         -> throwString s

parseVerbosity_Maybe :: ParseM Maybe Verbosity
parseVerbosity_Maybe = parseVerbosity

given

data Verbosity = Concise | Verbose

instance Default Verbosity where def = Concise

Also see ParseM.

type ParseM m a = String -> m a Source #

Simple parser.

Usage:

Here is an example parser,

parseVerbosity :: (MonadThrow m) => Parse m Verbosity
parseVerbosity s = go s

  where
  go = case
  
    "concise" -> return Concise
    "verbose" -> return Verbose
  
    "Concise" -> return Concise
    "Verbose" -> return Verbose
  
    "default" -> return def
  
    _         -> throwString s

parseVerbosity_Maybe :: Parse Maybe Verbosity
parseVerbosity_Maybe = parseVerbosity

given

data Verbosity = Concise | Verbose

newtype Tokens Source #

Under tokenization (i.e. parsing into tokens), some information about capitalization must be preserved.

For example, this "word":

GHCVersion

is represented as (and should be parsed into):

[ toAcronymToken "GHC"
, toSubwordToken "Version"
] :: Tokens

which is equivalent to (i.e. lower-cased and without the smart-constructors):

[ AcronymToken "ghc"
, SubwordToken "version"
] :: Tokens

restyleString :: TokenizationConfig -> String -> String Source #

Example
  1. We have an Enum whose constructors' names:
  • are class-cased (the conventional styling);
  • are suffixed by the name of their type;
  • and may have acronyms (i.e. an alpha-numeric sequence, with all letters being upper-case).

e.g.:

data Query

  = WindowIdQuery
  | WMClassQuery

  deriving (Enum,Bounded,Show,Read)
  1. We want to render its constructors' names, as the valid values of a command-line option

i.e.:

printQueryForCmdLn :: Print Query
printQueryForCmdLn WindowIdQuery = "window-id
printQueryForCmdLn WMClassQuery  = "wm-class

NOTE the acronym WM is (correctly) grouped into a single Token; c.f. the (incorrectly) un-grouped "w-m-class", which is less legible.

  1. We can also print it as an idiomatic command-line option, by (type) name.

i.e.:

printQueryAsLongOptionAndShortOption :: (String, Char)
printQueryAsLongOptionAndShortOption = ("query", q)

e.g. (assuming an executable named ./example):

$ ./example --query=window-id
$ ./example -q wm-class

restyleClassCasedToHyphenated :: String -> String Source #

Specializes restyleString; with ClassCase, HyphenCase, and UpperCasedAcronym.

>>> restyleClassCasedToHyphenated "WMClass"
"wm-class"
>>> restyleClassCasedToHyphenated "WindowId"
"window-id"

intersperseBySeparator :: WordSeparator -> NonEmpty String -> NonEmpty String Source #

>>> :set -XOverloadedStrings
>>> :set -XOverloadedLists
>>> toList (intersperseBySeparator (WordSeparator (Just '-')) ["cabal","new","build"])
["cabal","-","new","-","build"]
>>> toList (intersperseBySeparator (WordSeparator Nothing) ["cabal","new","build"])
["cabal","new","build"]
