Synopsis

The Options Tutorial

This API module provides the generic types used to specify the options when compiling REs for each of the backl ends.

See the tutorials at http://re-tutorial-options.regex.uk

SimpleREOptions

data SimpleREOptions Source #

the default API uses these simple, universal RE options, which get auto-converted into the apropriate back-end REOptions_

Constructors

MultilineSensitive

case-sensitive with ^ and $ matching the start and end of a line

MultilineInsensitive

case-insensitive with ^ and $ matsh the start and end of a line

BlockSensitive

case-sensitive with ^ and $ matching the start and end of the input text

BlockInsensitive

case-insensitive with ^ and $ matching the start and end of the input text

Instances

Bounded SimpleREOptions Source # 
Enum SimpleREOptions Source # 
Eq SimpleREOptions Source # 
Ord SimpleREOptions Source # 
Show SimpleREOptions Source # 
Lift SimpleREOptions Source #

we need to use this in the quasi quoters to specify SimpleREOptions selected by the quasi quoter

Methods

lift :: SimpleREOptions -> Q Exp #

IsOption SimpleREOptions Source # 

REOptions_

data REOptions_ r c e Source #

the general options for an RE are dependent on which back end is being used and are parameterised over the RE type for the back end, and its CompOption and ExecOption types (the compile-time and execution time options, respectively); each back end will define an REOptions type that fills out these three type parameters with the apropriate types (see, for example, Text.RE.TDFA)

The Macro Tables

type Macros r = HashMap MacroID r Source #

our macro tables are parameterised over the back end RE type and and just associate each MacroID with an RE (which may in turn contain macros to be expanded)

newtype MacroID Source #

MacroID is just a wrapped String type with an IsString instance

Constructors

emptyMacros :: Macros r Source #

a macro table containing no entries
