fromString -package:os-string

O(1). A Builder taking a String, satisfying

• toLazyText (fromString s) = fromChunks
  [S.pack s]

Performs replacement on invalid scalar values:

>>> fromString "\55555"
"\65533"

Converts a Haskell string into a UTF8 encoded bytestring.

Converts a Haskell string into a UTF8 encoded bytestring.

Converts a Haskell string into a UTF8 encoded string. Complexity: linear.

If the passed in String can be parsed as a UUID, it will be. The hyphens may not be omitted. Example:

>>> fromString "c2cc10e1-57d6-4b6f-9899-38d972112d8c"
Just c2cc10e1-57d6-4b6f-9899-38d972112d8c

Hex digits may be upper or lower-case.

O(n). Serialize a Unicode String using the UTF-8 encoding.

O(n). Serialize the lower 8-bits of all characters of a string

Construct/pack from String

>>> fromString []
""

>>> fromString ['a','b','c']
"abc"

>>> fromString ['\55295','\55296','\57343','\57344'] -- U+D7FF U+D800 U+DFFF U+E000
"\55295\65533\65533\57344"

Note: This function is total because it replaces the (invalid) code-points U+D800 through U+DFFF with the replacement character U+FFFD.

Convert a String consisting of only characters in the ASCII block to a byte sequence. Any character with a codepoint above U+007F is replaced by U+0000.

Convert a String consisting of only characters representable by ISO-8859-1. These are encoded with ISO-8859-1. Any character with a codepoint above U+00FF is replaced by an unspecified byte.

Construct a CharIterator from a Unicode string.

See fromText.

Encode String to ByteString using UTF-8.

Encode a Unicode string to Path using strict UTF-8 encoding on Posix. On Posix it may fail if the stream contains null characters. TBD: Use UTF16LE on Windows.

A shorthand for maybeParsed . parseString

fromString qm sep text parses text into a spreadsheet, using the quotation character qm and the separator character sep.

>>> Spreadsheet.fromString '"' '\t' "\"hello\"\t\"world\"\n\"end\"\n"
Exceptional {exception = Nothing, result = [["hello","world"],["end"]]}

>>> Spreadsheet.fromString '"' ',' "\"hello,world\",\"really\"\n\"end\"\n"
Exceptional {exception = Nothing, result = [["hello,world","really"],["end"]]}

>>> Spreadsheet.fromString '"' ';' "\"hello \"\"world\"\"\"\n\"really\"\n"
Exceptional {exception = Nothing, result = [["hello \"world\""],["really"]]}

>>> Spreadsheet.fromString '"' ',' "\"hello\nworld\"\n"
Exceptional {exception = Nothing, result = [["hello\nworld"]]}

MF.fromString parses a Text value in MetaFont syntax, and attempts to return a TrailLike. Only a subset of Metafont is supported; see the tutorial for details.
