source: Moved the option variables out of global space and into
`struct m4'; made `m4_symtab' a real datatype, so that it's api
is not marred passing `struct m4' around just so it can decide
whether to keep traced symbol names or not. Added setters and
getters for the formerly global option variables, and obviously
changed a vast number of functions to take a `struct m4' and use
the getter funcs to find option values.
* m4/utility.c (interactive, sync_output, debug_level)
(no_gnu_extensions, prefix_all_builtins, suppress_warnings)
(max_debug_argument_length, warning_status, nesting_limit)
(discard_comments): Removed.
* m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
(debug_level, max_debug_argument_length, prefix_all_builtins)
(suppress_warnings, discard_comments, interactive, sync_output):
Removed from here...

this structure.

(m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
(m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
macros for the new fields.
* m4/m4module.h (m4_context_field_table)
(m4_context_opt_bit_table): Helper macros used to generate
prototypes, setters and getters for new option fields
consistently.

(m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
(m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
setter and getter functions generated by cpp from
m4_context_field_table and m4_context_opt_bit_table, exported as
part of the module api. Changed all callers.
* m4/symtab (struct m4_symtab): Used as the concrete type for
m4_symtab now.
(m4_symtab_create): Allocate and initialise a new struct.
(m4_symtab_apply): New function that works like m4_hash_apply, but
with different callbacks specific to symbol tables. Changed all
callers.
(symbol_destroy, arg_destroy, arg_copy): Renamed
symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
they have unused parameters for a reason!
(dump_symbol_CB): New callback to dump the contents of a single
symbol.
(symtob_dump): Rewritten in terms of dump_symbol_CB.
* m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
Changed all callers.
* m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
of the contained `m4_symtab' at the `no_gnu_extensions' field.
Although I'm not convinced these semantics are correct, they are
at least consistent with how things were before this delta. Also
set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.

functions for modularisation later.

with create a `struct m4' context container, and replace
`m4__symtab' with `context->symtab' throughout. This means
initialising a context container in main, and adjusting many
functions between main and the module entry points so that the
container gets passed through. It would have been nice to
defer this until after 1.5, but it has a major effect on the
user's module writing ABI, so it needs to be addressed now - at
least in the areas that impact the ABI. An interrelatated change
in the symtab API removes the dependency on a global symbol table,
and instead focuses on a passed table (from the context
container).
* TODO: Reminders for finishing context functionality.
* m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
* m4/m4.c: New file. Manage new struct m4 objects to eliminate
global variables and eventually allow m4 to be reentrant.
* m4/m4private.h (m4): Define the new structure here...
(M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
don't carry the overhead of a function call.
* m4/m4module.h: Prototype extern functions from m4/m4.c.
(m4): Declare type for new struct m4 objects.
(M4SYMTAB): User macro to ease finding the symbol table for the
current context for module developers.
(m4_symbol_token): Renamed to m4_symbol_set_token which contains a
verb.

(m4_macro_pushdef, m4_macro_table_install, m4_module_load)
(m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
m4* context parameter. Changed definitions and all callers.
(m4_symtab): Alias for m4_hash to decouple the
m4_symtab api from m4_hash.
(m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
m4_hash.
(m4_symtab_create): New function to return an initialised
m4_symtab.
(m4_symtab_delete): New function to delete an m4_symtab's memory.
(m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
(m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
instead of simply using the global m4__symtab. Changed
definitions and all callers.
* m4/m4private.h (m4__symtab_remove_module_references): Ditto.
* m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
* src/main.c (main): Create a context and use that instead of the
former global m4__symtab.

argument range checking, tabulate the maxima and minima for all
builtins in each module. This forces us to consider what the
valid ranges for each builtin should be, and moves the checking
code out of each builtin implementation and into the builtin
caller infrastructure.
* m4/m4module.h (struct m4_builtin): Add argument minima and
maxima.
* m4/m4private.h (struct m4_token): Reflect them here too.
* m4/input.c (struct input_block): ...and here.
(m4_token_copy): New function for token copying.
(init_macro_token): Copy them from a token to the input stack.
(m4_next_token): Don't forget to initialise them for text
macros.
* m4/macro.c (expand_argument): Use m4_token_copy, and also
check argument counts before calling the builtin handler.
* m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
(m4_symbol_macro): Likewise.
* m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
parameters. Updated all callers.

For as long as a traceon(`foo') is active, calls to foo will be
traced regardless of intervening undefines or module unloads.
Fixed the flag propogation issues differently to the fixes
reverted with the last attempt at nailing down trace:
* m4/m4private.h: This file is not visible outside of the m4
source tree, so I removed all the `M4_' and `m4_' prefixes to save
on typing. Updated all clients.
(m4_token): New typedef contains the fields that need to be passed
around with the low level tokeniser.
(m4_token_data): Removed.
(m4_symbol): Now contains the traced flag again.
* m4/symtab.c: Rewritten again. Now we don't remove symbols with
the trace bit set. This change is contained entirely within this
module and doesn't leak out into the callers. Updated all
clients.
(m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
new fields in m4_token. Updated all clients.
* m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
that `groks_macro_args' and `blind_if_no_args' flags are retained
when defn() results are passed around in m4 code. Updated all
callers.
(m4_builtin_define): Ditto.
(m4_macro_pushdef, m4_macro_define): Ditto.
* m4/input.c (struct input_block): Add a flags field to facilitate
the above.
(m4_push_macro): ...use it.
(init_macro_token): Retrieve it.
(m4_next_token): Initialise it.
* m4/macro.c (expand_argument): Copy it.
* m4/m4module.h: Adjust.
* tests/builtins.at: Adjust the expected output of the trace
tests to reflect the change in semantics.
* tests/modules.at (modules: trace): Check that unloading a
module which supplies a traced symbol definition doesn't lose te
trace bit.

structure on 2001-09-20. We are still not happy about the way
trace works in conjunction with defn and undefine, and leaving
the reverted patch active prevents us from moving the traced
bit from the definition back to the symbol.
|
|
|
* modules/evalparse.c: ...here. This code is shared between
modules/mpeval.c and modules/m4.c, so there is no need to pollute
the libm4 API with its details. Moderately rewritten to interface
into its clients more simply.
* m4/eval.c: Deleted. Migrated functionality to...
* modules/m4.c: ...here.
(builtin_eval): Implemented in terms of the new interface style.
* modules/mpeval.c (builtin_mpeval): Ditto.
* m4/m4module.h: Removed references to the former m4/eval.c.
* m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
(EXTRA_libm4_la_SOURCES): Deleted.
* modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
(EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
