Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the tests
that check compiler error messages, expect the new line numbers.
browser/cterm.m:
browser/tree234_cc.m:
Import only one module per line.
tests/hard_coded/boyer.m:
Fix something I missed.
Estimated hours taken: 1
Fix a bug reported by Ralph Becket which caused a compiler abort
if the user declared the modes but not the types for a field
access function.
compiler/typecheck.m:
In the clause introduced when the user declares the modes
of a field access function, make sure the var-functor
unification can only be interpreted as a field access,
not a recursive function call.
Add field labels to the typecheck_info type.
tests/invalid/record_syntax_errors.m:
tests/invalid/record_syntax_errors.err_exp:
Add a test case.
doc/reference_manual.texi:
Clarify the documentation.
Estimated hours taken: 70
Implement syntax for getting and setting fields of constructors.
compiler/make_hlds.m:
Add information about field definitions to the module_info.
Check that user-defined field access functions for exported
fields are also exported, otherwise predicates in other modules
could use a different method to access a field than predicates
in module defining the field.
Add a `predicate preds_add_implicit_report_error' to allow that check
to be performed for functions which are added to the module_info
by some means other than a `:- func' declaration.
Parse field access goals and expressions.
Add predicates `insert_arg_unifications_with_supplied_contexts',
and `append_arg_unification', which allow more control over
the contexts given to the added unifications. These are
useful because the field value for an update is really an
argument of the inner-most update function call, while the
input term is an argument of the outer-most function call.
compiler/prog_io_dcg.m:
Allow DCG goals of the form `:=(DCGArg)', which unifies `DCGArg'
with the output DCG argument, ignoring the input DCG argument.
The rationale for this change is that if we have convenient syntax
for updating parts of a DCG argument, we should also have convenient
syntax for updating the whole DCG argument.
compiler/typecheck.m:
Add a default clause for field access functions for which
the user has supplied type and mode declarations but no
clauses.
Typecheck field access function calls.
Use `io__write_list' to remove some duplication of code
to write out comma separated lists of error descriptions.
compiler/post_typecheck.m:
Expand field accessor goals into the equivalent unifications.
They are expanded inline rather than generating new get and set
predicates for field name to avoid having to work out how to mode
the generated predicates.
Remove an unnecessary goal traversal to qualify function
calls and constructors. That code is now called from purity.m.
compiler/prog_data.m:
compiler/prog_io.m:
compiler/mercury_to_goedel.m:
compiler/mercury_to_mercury.m:
Store field names as `sym_name's rather than strings.
Use a `maybe' type rather than an empty string to designate
an unlabelled field.
compiler/hlds_data.m:
Define data structures to hold information about
the field names visible in a module.
compiler/hlds_module.m:
Add a field to type module_info to hold information
about the fields visible in a module.
compiler/hlds_pred.m:
Add predicates to identify field access function names,
and to handle the arguments of field access functions.
compiler/make_hlds.m:
compiler/hlds_goal.m:
compiler/modecheck_call.m:
compiler/higher_order.m:
compiler/purity.m:
compiler/polymorphism.m:
compiler/dnf.m:
compiler/cse_detection.m:
compiler/lambda.m:
Move `create_atomic_unification' from make_hlds.m to hlds_goal.m
because it is used by several other modules.
compiler/hlds_goal.m:
Add a version of goal_info_init which takes the context of
the goal, for use by make_hlds.m.
compiler/type_util.m:
Add a predicate `type_util__get_type_and_cons_defn' to
get the hlds_type_defn and hlds_cons_defn for a user-defined
constructor.
compiler/prog_util.m:
Add predicates to add and remove prefixes or suffixes
from the unqualified part of a sym_name.
compiler/prog_out.m:
Add a predicate to convert a `sym_name/arity' to a string.
compiler/hlds_out.m:
Add `hlds_out__simple_call_id_to_string' to convert a
`pred_or_func - sym_name/arity' to a string for use in
error messages.
compiler/purity.m:
Thread through the pred_info so that the expansion of field accessor
goals can add new variables.
compiler/mercury_to_mercury.m:
library/ops.m:
Reduce precedence of `^/2' for use as a field name separator.
Add operator `^'/1 to designate which side of the `:=' is
the field name in a DCG field access goal.
Add operator `:=/2' for field update expressions.
doc/reference_manual.texi:
Document the new syntax.
doc/transition_guide.texi:
Document the new operators.
