branch: devel-rpplx-external-except
commit 7ae31dcf217d927ab5b447932758a1af6ac37ae4
Author: rpplx <address@hidden>
Date: Mon Jul 3 11:48:15 2017 +0200
Added support for run time management of trace, warning and assert feedback.
By default GMM macros such as GMM_ASSERT*, GMM_WARNING*, print feedback
messages to std::cerr. A customisation could be done by defining
EXTERNAL_EXCEPT_ and providing header file external_except.h that overrides
specific macros. This introduces however source code dependency.
This commit provides new mechanism to specify feedback handling on run
time. Default behaviour of GMM is preserved and no changes to existing code are
necessary. Users willing to send feedback somewhere else and take different
action on catching exception can provide user defined class derived from
gmm::base_feedback_handler and set it in gmm::feedback_manager. The default GMM
behaviour is implemented in gmm::default_feedback_handler.
Changes: outline:
1. Code formatting : changed tabs to spaces
2. gmm_error exception now can optionally take integer argument (used for
instance as severity level).
3. New macro GMM_THROW_AT_LEVEL to throw exception with specified level
value.
4. structures warning_level, traces_level moved to gmm_feedback_management.h
5. Macros: GMM_WARNING_MSG, GMM_TRACE_MSG, GMM_WARNING*, GMM_ASSERT* and
GMM_STANDARD_CATCH_ERROR now use the new feedback mechanism.
6. Fix for GMM_PRETTY_FUNCTION of Windows
7. Removed dependency on EXTERNAL_EXCEPT_ and inclusion of
external_except.h header.
