Estimated hours taken: 16 Branches: main, release Replace the "set" command of mdb with a bunch of commands: the `format', `format_param', `list_context_lines', `list_path', `xml_browser_cmd', `xml_tmp_filename', `fail_trace_counts', `pass_trace_counts' and `max_io_actions' commands. Each of these set just one parameter or one of set of closely related parameters. Move all these commands, and some existing commands that set parameters that were elsewhere, to the "parameter" command category. Extend some of these commands so that if given no arguments, they report the current values of the parameters they would otherwise set. Replace the "set" commands of the mdb browser and of the declarative debugger with a bunch of commands: "format", "depth", "size", "width", "lines", "actions" and "params" (the last prints the current value of the parameters). For each category of mdb commands, create files mercury_trace_cmd_<cat>.[ch], and move the functions dealing with that category of commands there from mercury_trace_internal.c. Give each of these new files a logical structure that was sometimes missing from the relevant parts of mercury_trace_internal.c. NEWS: Mention these changes. doc/mdb_categories: Document these changes. doc/user_guide.texi: Document these changes. Fix an old documentation bug: you couldn't set listing paramaters from a declarative debugger command. Fix an old documentation bug: the description of the goal_path step for scopes was obsolete. Fix some obsolete references to : as module qualifier. browser/parse.m: Update the browser command set along the lines at the top. browser/declarative_user.m: Update the declarative debugger command set along the lines at the top. Move the declaration for the type representing declarative debugger commands to near the top of the file. browser/browser_info.m: Provide some access predicates. Update the predicate that generates mdb commands to save the persistent state of the debugger to generate the new forms of parameter commands. Move types and predicates for dealing with browser parameters from browse.m to here, so that declarative_user.m can use them too. browser/browse.m: Delete the code moved to browser_info.m, and conform to the other changes in the other modules. browser/listing.m: Provide a predicate to return the type of listing paths. scripts/mdbrc.in: Update the commands that set the XML parameters. scripts/Mmakefile: Get mmake to rebuild mdbrc from mdbrc.in when mdbrc.in changes. trace/mercury_trace_internal.c: trace/mercury_trace_cmds.h: trace/mercury_trace_cmd_*.[ch]: Implement the changes described at the top. Fix an old bug: the commands that update the search path for the "list" command don't make the search path term permanent, which is needed in non-conservative-gc grades. trace/mercury_trace_spy.c: Fix some obsolete references to : as module qualifier. trace/mercury_trace_browse.[ch]: Delete the functionality now moved to mercury_trace_cmd_parameter.c. tests/debugger/mdb_command_test.inp: Update the set of commands being tested. tests/debugger/save.{inp,exp}: Update the parameter commands in this test case.	2006-04-04 07:37:31 +00:00
Zoltan Somogyi	b51c742885	Allow the debugger to print higher order values and typeinfos, mainly by ... Estimated hours taken: 50 Branches: main Allow the debugger to print higher order values and typeinfos, mainly by making the committed choice modes of the predicates in deconstruct.m to deconstruct higher order values and typeinfos. (The non committed choice versions will continue to return only placeholders.) Having the debugger print typeinfos is occasionally useful but more often it is just distracting. This change therefore adds a new debugger command, "print_optionals", that toggles the printing of optional values. For now, the only optional values are typeinfos. NEWS: Mention the new capability and the new predicates in the library. Mention the predicates added previously that allow the caller to specify how non-canonical terms should be handled, since the change in their semantics that we anticipated when they were added has now happened, and their semantics should now be more stable. browser/browser_info.m: Use the predicates in the deconstruct.m instead of std_util, to make the choice of noncanonical term method handling explicit. browser/browse.m: When writing small terms using io__write_univ, explicitly use the same noncanonical term handling method as browser_info.m library/io.m: Add predicates to retrieve the current input and output streams. Add versions of io__write_univ that specify the stream and maybe the method of handling noncanonical terms. Add a mode to io__write_list that allows the closure that prints the list elements to be cc_multi. All of these are for the new functionality in the browser. runtime/mercury_ml_expand_body.h: In committed choice contexts, deconstruct closures as if they were ordinary terms, with the function symbol being the name of the predicate/function and the arguments being the terms stored in the closure. In committed choice contexts, deconstruct typeinfos as if they were ordinary terms, with the function symbol being the name of the type constructor and the arguments being the type constructor's arguments. runtime/mercury_type_info.[ch]: Add a new function, MR_collapse_ctor_equivalences, for use by mercury_ml_expand_body.h. Delete a redundant function comment. library/deconstruct.m: Document the changes in the behavior of the predicates defined in this module as a result of the change to mercury_ml_expand_body.h. runtime/mercury_ho_call.h: runtime/mercury_stack_layout.h: Add prefixes on structure field names that did not have them. browser/dl.m: Add prefixes where needed by the changes to mercury_ho_call.h. runtime/mercury_layout_util.[ch]: Remove the first argument of MR_materialize_closure_typeinfos, since its correct value is always the same part of the second argument. runtime/mercury_deep_copy_body.h: Do not pass the first argument of MR_materialize_closure_typeinfos. Add field name prefixes where necessary. compiler/modules.m: The mercury_builtin module is no longer part of the library. compiler/pd_debug.m: compiler/rl_analyze.m: Minor updates to avoid trying to take the address of io__write_list, since it now has more than one mode. runtime/mercury_init.h: runtime/mercury_wrapper.[ch]: trace/mercury_trace_vars.[ch]: Add a parameter to MR_trace_browse_all_on_level that specifies whether we should print values of type type_info. trace/mercury_trace_vars.c: Do not ignore predicates and functions anymore. runtime/mercury_stack_trace.c: trace/mercury_trace.c: trace/mercury_trace_declarative.c: trace/mercury_trace_external.c: Pass the new parameter of MR_trace_browse_all_on_level. trace/mercury_trace_internal.c: Implement the "print_optionals" command. doc/user_guide.texi: Document the "print_optionals" command. tests/debugger/mdb_command_test.inp: Test the documentation of "print_optionals". tests/debugger/higher_order.{m,inp,exp,exp2}: A new test case to exercise the ability to print higher order values. Note that the format of the predicate names in the output should be improved, but that is a separate change since doing it the right way requires bootstrapping. tests/debugger/Mmakefile: Enable the new test case. tests/debugger/nondet_stack.exp*: Update the expected output to reflect the fact that nondet stack dumps, being intended for debugging, include type_infos. tests/debugger/tabled_read_decl.exp*: Update the expected output to reflect the fact that for maximum usefulness, the printing of I/O action atoms prints meaningful type_infos. tests/hard_coded/deconstruct_arg.*: tests/hard_coded/write_reg1.*: Expand these tests to check that we handle higher order values correctly not just when canonicalizing but also in committed choice modes.	2002-02-24 11:53:46 +00:00
