WebCoq represents a string as a list-like Inductive of Ascii characters: Locate string. (* Coq.Strings.String.string *) Print string. (* Inductive string : Set := EmptyString : string String : Ascii.ascii -> string -> string *) The C programming language represents a character as a byte, that is, an 8-bit signed or unsigned integer. Strings that involve ascii characters of code >= 128 which are not part of a valid utf8 sequence of characters are not representable using the Coq string notation (use explicitly the String constructor with the ascii codes of the characters). Module Export StringSyntax. WebThe string fields are the Coq version, the protocol version, the release date, and the compile time of Coqtop. The protocol version is a date in YYYYMMDD format, where "20150913" corresponds to Coq 8.6. An IDE that wishes to support multiple Coq versions can use the protocol version information to know how to handle output from Coqtop. crepusculo doblaje wiki
