prog_io.nl:
An error message was omitting the file name & line number.
Also ensure that all error messages start with "error:".
codegen.nl, interpreter.nl, bintree.nl, list.nl:
Fix stuff detected by nit.
make_hlds.nl:
Transform to `semi-homogeneous' form (still need to expand
unifications).
prog_util.nl:
Fix bug.
mercury_builtin.nl:
Add call/1.
hlds.nl:
Add a count of the number of errors and warnings to the module_info
data structure.
toplevel.nl:
Continue processing after syntax errors.
varset.nl:
Added predicate varset__vars.
term.nl:
Added predicate term__vars_list.
typecheck.nl:
Implement two previously unimplemented parts of the typechecker:
detect attempts to instantiate type variables which occur in
the predicate's type declaration, and detect any failure to
bind all other type variables. (That was the last two;
apart from
prog_util.nl:
Fix problem where the expansion of equivalence types was
introducing fresh variables into the type varset, which caused
problems in relation to the above changes to typecheck.nl.
hlds_out.nl:
Fix typo in type declaration (found by above fixes to typechecker).
options.nl:
Fix bug in type definition introduced by last change.
make_hlds.nl:
Add a missing pred & mode declaration.
modes.nl:
Don't display the verbose messages unless the very-verbose
flag was specified.
prog_util.nl:
Changed if-then-else to -> ;
string.nl:
Changed if-then-else to -> ;
term.nl:
Changed if-then-else to -> ; and added an XXX in term__context_init
varset.nl:
Changed if-then-else to -> ;
modes.nl:
New file. At the moment it just checks for undefined modes and
undefined insts.
Makefile, doit.nl:
Add new files modes.nl and prog_util.nl.
term.nl:
Add term__var_to_int.
toplevel.nl:
Call the mode checker.
prog_io.nl, make_hlds.nl, hlds.nl:
Allow for the possibility of abstract `inst' definitions,
just like abstract type definitions. Currently they
are allowed for in the data structure, but they aren't
parsed correctly, and the utilities in hlds.nl don't handle
them that well.
hlds.nl:
Move `unqualify_name' to prog_util.nl.
make_hlds.nl:
Move `split_types_and_modes' to prog_util.nl.
mercury_to_goedel.nl, toplevel.nl:
Move the equivalence type expansion code to prog_util.nl.
builtin.nl, toplevel.nl:
Add a new module `builtin.nl' which gets automatically imported
into every module. In it, define the standard modes input,
output, etc., and various other stuff.
std_util.nl:
Move the defintion for \= to builtin.nl.
Remove the definition of ~=.
prog_io.nl:
Export parse_goal/2, since it's used by mercury_to_goedel.
mercury_to_goedel.nl:
Fix various type errors.
list.nl, int.nl, io.nl, codegen.nl, det_analysis.nl, llds.nl, hlds_out.nl:
Fix various syntax errors, typos and errors in type and mode
declarations discovered by mercury_compile.
