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.
+ Move type CommandInfo from GF.Command.Commands to a new module
GF.Commands.CommandInfo and make it independent of the PGF type.
+ Make the module GF.Command.Interpreter independent of the PGF type and
eliminate the import of GF.Command.Commands.
+ Move the implementation of the "help" command to its own module
GF.Command.Help
By adding unlexer=none (or unlexer=id) in requests that output linearizations
(e.g. command=linearize, command=translate), you can leave &+ uninterpreted
instead of gluing the adjacent tokens. This means that the output is left in
a format that can be parsed in a subsequent request.
To implement this consistently, the function linearizeAndBind was replaced
with the function linearizedAndUnlex (but there are a couple of requests
that do not call this function...)
Note that this applies to the Haskell run-time requests only. The C run-time
request (c-linearize, c-translate) always applies the &+ token and the
c-parse request can parse input containing glued tokens.
