Module `Conan_string`Source

recognition.

Conan_string is a system-free implementation of the file recognition. This implementation does not uses any syscalls - and it can be safely used into a MirageOS example.

So Conan_string does not have an access to a database. The user must rebuild a Conan.Tree.t by himself/herself via tree_of_string for example. Then, from this tree, the user is able to recognize a payload as a simple string with run:

  let v =
    {file|0       byte    0x66
  >1      byte    0x6f
  >>1     byte    0x6f    foo header
  |file}

  let tree = match Conan_string.tree_of_string v with
    | Ok tree -> tree
    | Error (`Msg err) -> failwith err

  let database = Conan.Tree.database ~tree

  let m = match Conan_string.run ~database contents with
    | Ok m -> m
    | Error (`Msg err) -> failwith err

Sourceval tree_of_string : string -> (Conan.Tree.t, [> `Msg of string ]) result

tree_of_string str tries to parse the given str as a decision tree according to the libmagic format.

Source

val run : 
  database:Conan.Process.database ->
  string ->
  (Conan.Metadata.t, [> `Msg of string ]) result

run ~database contents tries to recognize the given contents with the help of database. The databse can be made via Conan.Process.database. Indeed, a Conan.Tree.t can have some indirect decision paths so we must pre-process the tree to agglomerate such indirections.
