Module `OpamFile.OPAM`

OPAM files

include IO_FILE

type t

File contents

val write : OpamTypes.filename -> t -> unit

Write some contents to a file

val read : OpamTypes.filename -> t

Read file contents. Raise an error if the file does not exist.

val safe_read : OpamTypes.filename -> t

Read file contents. Return empty if the file does not exist.

val read_from_channel : ?filename:OpamTypes.filename -> in_channel -> t

Read from channel.

val read_from_string : ?filename:OpamTypes.filename -> string -> t

val write_to_channel : out_channel -> t -> unit

val empty : t

val create : OpamTypes.package -> t

Create an opam file

val template : OpamTypes.package -> t

Create an OPAM package template filled with common options

val validate : t -> (int * [ `Warning | `Error ] * string) list

Runs several sanity checks on the opam file; returns a list of warnings. `Error level should be considered unfit for publication, while `Warning are advisory but may be accepted. The int is an identifier for this specific warning/error.

val validate_file : 
  OpamTypes.filename ->
  (int * [ `Warning | `Error ] * string) list * t option

Same as validate, but operates on a file, which allows catching parse errors too. You can specify an expected name and version

val validate_string : 
  OpamTypes.filename ->
  string ->
  (int * [ `Warning | `Error ] * string) list * t option

Like validate_file, but takes the file contents as a string

val warns_to_string : (int * [ `Warning | `Error ] * string) list -> string

Utility function to print validation results
