Variant of the t mustache datatype which includes source-file locations, and associated functions.

}

  1. | String of string

and section = {
  1. name : dotted_name;
  2. contents : t;
}
and partial = {
  1. indent : int;
  2. name : name;
  3. contents : t option Stdlib.Lazy.t;
}

  2. desc : desc;
}
val dummy_loc : loc

A value of type loc, guaranteed to be different from any valid location.

val parse_lx : Stdlib.Lexing.lexbuf -> t

Read

val of_string : string -> t
val pp : Stdlib.Format.formatter -> t -> unit

pp fmt template print a template as raw mustache to the formatter fmt.

val to_formatter : Stdlib.Format.formatter -> t -> unit

Alias for compatibility

val to_string : t -> string

to_string template uses to_formatter in order to return a string representing the template as raw mustache.

val render_fmt : ?strict:bool -> ?partials:(name -> t option) -> Stdlib.Format.formatter -> t -> Json.t -> unit

render_fmt fmt template json render template, filling it with data from json, printing it to formatter fmt.

For each partial p, if partials p is Some t then the partial is substituted by t. Otherwise, the partial is substituted by the empty string is strict is false. If strict is true, the Missing_partial exception is raised.

val render : ?strict:bool -> ?partials:(name -> t option) -> t -> Json.t -> string

render template json use render_fmt to render template with data from json and returns the resulting string.

val fold : string:(loc:loc -> string -> 'a) -> section:(loc:loc -> inverted:bool -> dotted_name -> 'a -> 'a) -> escaped:(loc:loc -> dotted_name -> 'a) -> unescaped:(loc:loc -> dotted_name -> 'a) -> partial:(loc:loc -> int -> name -> t option Stdlib.Lazy.t -> 'a) -> comment:(loc:loc -> string -> 'a) -> concat:(loc:loc -> 'a list -> 'a) -> t -> 'a

fold template is the composition of f over parts of template, called in order of occurrence, where each f is one of the labelled arguments applied to the corresponding part. The default for f is the identity function.

  • parameter string

    Applied to each literal part of the template.

  • parameter escaped

    Applied to "name" for occurrences of {{name}}.

  • parameter unescaped

    Applied to "name" for occurrences of {{{name}}}.

  • parameter partial

    Applied to "box" for occurrences of {{> box}}.

  • parameter comment

    Applied to "comment" for occurrences of {{! comment}}.

val expand_partials : (name -> t option) -> t -> t

expand_partials f template is template where for each Partial p node, p.contents now evaluates to f p.name if they were evaluating to None. Note that no lazy is forced at this point, and calls to f are delayed until p.contents is forced.

module Infix : sig ... end

Shortcut for concatening two templates pieces.

val raw : loc:loc -> string -> t

<p>This is raw text.</p>

val escaped : loc:loc -> dotted_name -> t

{{name}}

val unescaped : loc:loc -> dotted_name -> t

{{{name}}}

val inverted_section : loc:loc -> dotted_name -> t -> t

{{^person}} {{/person}}

val section : loc:loc -> dotted_name -> t -> t

{{#person}} {{/person}}

val partial : loc:loc -> ?indent:int -> name -> t option Stdlib.Lazy.t -> t

{{> box}}

val comment : loc:loc -> string -> t

{{! this is a comment}}

val concat : loc:loc -> t list -> t

Group a t list as a single t.
