Parser for a format with a builder.

Equations

• Std.Time.GenericFormat.builderParser format config func = Std.Time.GenericFormat.builderParser.go✝ config format func

def Std.Time.GenericFormat.parse {aw : Awareness} (format : GenericFormat aw) (input : String) : Except String aw.type

Parses the input string into a ZoneDateTime.

Equations

• format.parse input = (Std.Time.GenericFormat.parser✝ format.string format.config aw <* Std.Internal.Parsec.eof).run input

def Std.Time.GenericFormat.parse! {aw : Awareness} (format : GenericFormat aw) (input : String) : aw.type

Parses the input string into a ZoneDateTime and panics if its wrong.

Equations

• format.parse! input = match format.parse input with | Except.ok res => res | Except.error err => panicWithPosWithDecl "Std.Time.Format.Basic" "Std.Time.GenericFormat.parse!" 1480 18 err

def Std.Time.GenericFormat.parseBuilder {aw : Awareness} {α : Type} (format : GenericFormat aw) (builder : FormatType (Option α) format.string) (input : String) : Except String α

Parses an input string using a builder function to produce a value.

Equations

• format.parseBuilder builder input = (Std.Time.GenericFormat.builderParser format.string format.config builder).run input

def Std.Time.GenericFormat.parseBuilder! {α : Type} {aw : Awareness} [Inhabited α] (format : GenericFormat aw) (builder : FormatType (Option α) format.string) (input : String) : α

Parses an input string using a builder function, panicking on errors.

def Std.Time.GenericFormat.formatGeneric {aw : Awareness} (format : GenericFormat aw) (getInfo : (typ : Modifier) → Option (TypeFormat typ)) : Option String

Formats the date using the format into a String, using a getInfo function to get the information needed to build the String.

Equations

• format.formatGeneric getInfo = Std.Time.GenericFormat.formatGeneric.go✝ getInfo "" format.string

def Std.Time.GenericFormat.formatBuilder {aw : Awareness} (format : GenericFormat aw) : FormatType String format.string

Constructs a FormatType function to format a date into a string using a GenericFormat.

Equations

• format.formatBuilder = Std.Time.GenericFormat.formatBuilder.go✝ "" format.string

class Std.Time.Format (f : Type) (typ : Type → f → Type) : Type 1

Typeclass for formatting and parsing values with the given format type.

• format (fmt : f) : typ String fmt

  Converts a format f into a string.

• parse {α : Type} (fmt : f) : typ (Option α) fmt → String → Except String α

  Parses a string into a format using the provided format type f.
