Description

Warning! This module is subject to change in the future, and therefore should not be relied upon to have a consistent API.

Synopsis

INI types

newtype RawIni Source #

An Ini value is a mapping from section names to IniSection values. The section names in this mapping are normalized to lower-case and stripped of whitespace. This sequence retains the ordering of the original source file.

data IniSection Source #

An IniSection consists of a name, a mapping of key-value pairs, and metadata about where the section starts and ends in the file. The section names found in isName are not normalized to lower-case or stripped of whitespace, and thus should appear exactly as they appear in the original source file.

Constructors

IniSection 

Fields

  • isName :: Text

    The name of the section, as it appears in the original INI source

  • isVals :: Seq (NormalizedText, IniValue)

    The key-value mapping within that section. Key names here are normalized to lower-case and stripped of whitespace. This sequence retains the ordering of the original source file.

  • isStartLine :: Int

    The line on which the section begins. This field is ignored when serializing, and is only used for error messages produced when parsing and deserializing an INI structure.

  • isEndLine :: Int

    The line on which the section ends. This field is ignored when serializing, and is only used for error messages produced when parsing and deserializing an INI structure.

  • isComments :: Seq BlankLine

    The blank lines and comments that appear prior to the section head declaration, retained for pretty-printing identical INI files.

data IniValue Source #

An IniValue represents a key-value mapping, and also stores the line number where it appears. The key names and values found in vName and vValue respectively are _not_ normalized to lower-case or stripped of whitespace, and thus should appear exactly as they appear in the original source file.

Constructors

IniValue 

Fields

  • vLineNo :: Int

    The line on which the key/value mapping appears. This field is ignored when serializing, and is only used for error messages produced when parsing and deserializing an INI structure.

  • vName :: Text

    The name of the key, as it appears in the INI source.

  • vValue :: Text

    The value of the key

  • vComments :: Seq BlankLine
     
  • vCommentedOut :: Bool

    Right now, this will never show up in a parsed INI file, but it's used when emitting a default INI file: it causes the key-value line to include a leading comment as well.

  • vDelimiter :: Char

data BlankLine Source #

We want to keep track of the whitespace/comments in between KV lines, so this allows us to track those lines in a reproducible way.

data NormalizedText Source #

The NormalizedText type is an abstract representation of text which has had leading and trailing whitespace removed and been normalized to lower-case, but from which we can still extract the original, non-normalized version. This acts like the normalized text for the purposes of Eq and Ord operations, so

  normalize "  x  " == normalize "X"

This type is used to store section and key names in the

Constructors

NormalizedText 

normalize :: Text -> NormalizedText Source #

The constructor function to build a NormalizedText value. You probably shouldn't be using this module directly, but if for some reason you are using it, then you should be using this function to create NormalizedText values.

serializing and deserializing

parseRawIni :: Text -> Either String RawIni Source #

Parse a Text value into an Ini value, retaining a maximal amount of structure as needed to reconstruct the original INI file.

printRawIni :: RawIni -> Text Source #

Serialize an INI file to text, complete with any comments which appear in the INI structure, and retaining the aesthetic details which are present in the INI file.

inspection

lookupInSection Source #

Arguments

:: Text

The section name. Will be normalized prior to comparison.

-> Text

The key. Will be normalized prior to comparison.

-> RawIni

The Ini to search.

Look up an Ini value by section name and key. Returns the sequence of matches.

lookupSection Source #

Arguments

:: Text

The section name. Will be normalized prior to comparison.

-> RawIni

The Ini to search.

-> Seq IniSection 

Look up an Ini section by name. Returns a sequence of all matching section records.

lookupValue Source #

Arguments

:: Text

The key. Will be normalized prior to comparison.

-> IniSection

The section to search.

-> Seq IniValue 

Look up an Ini key's value in a given section by the key. Returns the sequence of matches.
