Lexer for Lambdapi syntax. Uses Sedlex, a Utf8 friendly lexer. Some helper functions to check if a string conflicts with the syntax are also provided.

Identifiers.

There are two kinds of identifiers: regular identifiers and escaped identifiers of the form "{|...|}".

Modulo those surrounding brackets, escaped identifiers allow to use as identifiers keywords or filenames that are not regular identifiers.

An escaped identifier denoting a filename or directory is unescaped before accessing to it. Hence, the module "{|a b|}" refers to the file "a b".

Identifiers need to be normalized so that an escaped identifier, once unescaped, is not regular. To this end, every identifier of the form "{|s|}" with s regular, is understood as "s" (function remove_useless_escape below).

Finally, identifiers must not be empty, so that we can use the empty string for the path of ghost signatures.

val is_regid : string -> bool
val escape : string -> string

escape s converts a string s into an escaped identifier if it is not regular. We do not check whether s contains "|}". FIXME?

val remove_useless_escape : string -> string

remove_useless_escape s replaces escaped regular identifiers by their unescape form.

val qid : bool -> string list -> Sedlexing.lexbuf -> token
val comment : int -> Sedlexing.lexbuf -> token
val token : Sedlexing.lexbuf -> unit -> token * Stdlib.Lexing.position * Stdlib.Lexing.position
