Gio.Application.id_is_valid

function id_is_valid(application_id: String): Boolean {
    // Gjs wrapper for g_application_id_is_valid()
}
  

Checks if application_id is a valid application identifier.

A valid ID is required for calls to Gio.Application.new and Gio.Application.prototype.set_application_id.

For convenience, the restrictions on application identifiers are reproduced here:

- Application identifiers must contain only the ASCII characters "[A-Z][a-z][0-9]_-." and must not begin with a digit.

- Application identifiers must contain at least one '.' (period) character (and thus at least three elements).

- Application identifiers must not begin or end with a '.' (period) character.

- Application identifiers must not contain consecutive '.' (period) characters.

- Application identifiers must not exceed 255 characters.
