WebPromise Prolog.consult ( ...Sources) Load the given Sources. Each source is either a file from the local file system, e.g., library (lists) or a URL. The sources are downloaded and processed sequentially. This uses Prolog.forEach () calling load_files/1. The returned Promise returns 1 on success. http://www.picat-lang.org/bprolog/example.html

For example, a complex rule of the form: WebWhen Prolog is in asynchronous mode, i.e., called through Prolog.forEach(), we can also load code from a URL. For example, we can load the CHAT80 demo program directly from GitHub using 232 The \ c continues the quoted atom from the next line after removing leading white space. http://www.hakank.org/constraint_programming_blog/2013/03/a_first_look_at_bprolog.html tally marks ppt
