While at a meeting today I had a period of time where I couldn't
easily sync with the Parrot repository to work on it, so I hacked
together a small script to automatically populate a new languages/
subdirectory with a "standard" compiler tools setup. The script
is attached.
With this script, one can do:
$ perl tools/dev/mk_language_shell.pl Xyz
The script will automatically create a languages/xyz/
directory with the following files (all customized to the
language being created):
xyz.pir
config/makefiles/root.in
src/parser/grammar.pg
src/parser/actions.pm
src/builtins/say.pir
t/harness
t/00-sanity.t
The script also runs the reconfigure step on the directory
to produce a Makefile from config/makefiles/root.in . So,
after running the above to create a compiler shell for 'Xyz',
one can immediately do:
$ cd languages/xyz
$ make test
../../parrot
/home/pmichaud/parrot/trunk/runtime/parrot/library/PGE/Perl6Grammar.pbc \
--output=src/gen_grammar.pir \
src/parser/grammar.pg
../../parrot /home/pmichaud/parrot/trunk/compilers/nqp/nqp.pbc
--output=src/gen_actions.pir \
--target=pir src/parser/actions.pm
/usr/bin/perl -MExtUtils::Command -e cat src/builtins/say.pir
>src/gen_builtins.pir
../../parrot -o xyz.pbc xyz.pir
/usr/bin/perl t/harness
t/00-sanity......ok
All tests successful.
Files=1, Tests=2, 0 wallclock secs ( 0.01 usr 0.01 sys + 0.06 cusr 0.01
csys = 0.09 CPU)
Result: PASS
$
After that the language implementor can start customizing the grammar,
actions, etc. for whatever language is being built.
Comments welcomed. Let me know if/when we want this script added
to tools/dev/ .
