Also, move the current PGF from CommandEnv to GFEnv in GF.Interactive, making the command interpreter even more generic. + Use a state monad to maintain the state of the interpreter in GF.{Interactive,Interactive2}. 2015-08-10T14:12:51+00:00 hallgren hallgren@chalmers.se 2015-08-10T14:12:51+00:00 urn:sha1:8d6e61a8df4480385a1f2ef29a96f6a88af9e3ba Some C run-time functionality is now available in the GF shell, by starting GF with 'gf -cshell' or 'gf -crun'. Only limited functionality is available when running the shell in these modes: - You can only import .pgf files, not source files. - The -retain flag can not be used and the commands that require it to work are not available. - Only 18 of the 40 commands available in the usual shell have been implemented. The 'linearize' and 'parse' commands are the only ones that call the C run-time system, and they support only a limited set of options and flags. Use the 'help' commmands for details. - A new command 'generate_all', that calls PGF2.generateAll, has been added. Unfortuntaly, using it causes 'segmentation fault'. This is implemented by adding two new modules: GF.Command.Commands2 and GF.Interactive2. They are copied and modified versions of GF.Command.Commands and GF.Interactive, respectively. Code for unimplemented commands and other code that has not been adapted to the C run-time system has been left in place, but commented out, pending further work. 2015-02-27T16:42:09+00:00 hallgren hallgren@chalmers.se 2015-02-27T16:42:09+00:00 urn:sha1:632aab83c3111d198f701de9e72878aa0ceb7015 Because the prompt included the name of the abstract syntax, the loading of the PGF was forced even if -retain was used. Even worse, if an error occured while loading the PGF, it was repeated and caught every time the prompt was printed, creating an infite loop. The solution is to not print the name of the abstract syntax when the grammar is imported with -retain, which is the way things were before anyway. 2015-02-27T13:49:13+00:00 hallgren hallgren@chalmers.se 2015-02-27T13:49:13+00:00 urn:sha1:e0bc6308e07edf4302242e434932c9da42c162bd The commands available in the shell after import -retain are now a superset of the commands available after import without -retain. The PGF is created lazily, so there should be no performance penalty if the PGF isn't needed. If there are errors, they won't be reported until a command that uses the PGF is entered. 2014-08-13T22:16:18+00:00 hallgren hallgren@chalmers.se 2014-08-13T22:16:18+00:00 urn:sha1:cd5193b7e19e7ff5e49cdeafe149fdeec8e19fb0
