val compare_ignore_case : string -> string -> int

Case-insensitive string comparison. Only ISO-8859-1 accents are handled.

val hash : string -> int

Same as String.hash but made available here until the minimal supported version of OCaml is 5.0.

val remove_prefix : ?strict:bool -> string -> string -> string option

remove_prefix ~strict prefix s returns None if prefix is not a prefix of s and Some s' iff s=prefix^s'.

val remove_suffix : ?strict:bool -> string -> string -> string option

remove_suffix ~strict suffix s returns None if suffix is not a suffix of s and Some s' iff s=s'^suffix.

val utf8_length : string -> int

Same as String.length but counts utf8 characters instead of bytes.

val utf8_escaped : string -> string

Same as String.escaped but for utf8 encoded strings. Unicode non ASCII characters are preserved unescaped.

val trim_underscores : string -> string

remove underscores at the beginning and end of a string. If a string is composed solely of underscores, return the empty string

val html_escape : string -> string

Escape string for use in HTML tag.

val percent_encode : string -> string

percent_encode s returns the string s encoded so that it can be used as a path component in a HTML URL. All characters not on the list of unreserved characters in RFC3986 are percent-encoded. For instance the space character is converted to %20.

Cf. https://datatracker.ietf.org/doc/html/rfc3986#section-2.3 for the list of unreserved characters.

val means_yes : string -> bool

Return true if the string is "yes", "true" or "1" (ignore case).
