Parameters
fsm_journal_event()fsm_journal_eventfsm.hfsm.hfsm_journal_eventvoid fsm_journal_event (int severity, int source, const char * file_source, const char * function_source, const char * string_value)It is mandatory for any event to call this function to be published in the journal. Before publication, a filter can be applied here (and only here) to select only some events of interest (during debugging, for example).If there are too many events, a filter can be applied here to select a few interesting events for publication in the log.This filter can operate on any the following five parameters: severity, source, *file_source, *function_source, *string_value. See alsobelow (params)
Simple filters (on a single parameter) can be combined using the logical operators 'and' and 'or' and parentheses.Use: $ grep -r "fsm_journal_event" to confirm the callergraph calls.Since2024-08See alsosrc/journal.c/fsm_journal_push_front()src/main/main() src/widget/topbar/modal.c src/widget/topbar/right.c src/widget/topbar/dialog.c src/widget/topbar/left.c src/widget/topbar/dispatch.c * 3 src/widget/one_rule/dispatch.c src/widget/one_rule/algebra/conditions.c * 2 src/widget/measure/dispatch.c src/widget/dispatch.c * 3 src/widget/all_rules/dispatch.c src/fsm/preferences/manager.c * 8 src/fsm/measures/manager.c * 2 src/fsm/measures/tools_list.c * 4 src/fsm/dispatch.c * 10 src/fsm/results/manager.c src/util/tree.c src/signal.c * 38
Parameters
severity<>
See alsoenum fsm_enum_journal_severity in include/fsm.h 'severity' is a pre-defined value that must be associated to each event. It ranges from zero to six : CRITICAL ERROR WARNING INFO MESSAGE DEBUG TRACE 0 1 2 3 4 5 6
Parameters
source<>
See alsoenum fsm_enum_journal_source in include/fsm.h 'source' is a pre-defined value that can be associated to each event. It is not mandatory. It can be set to 'NULL'.
Parameters
*file_source<> the name of the file that emits the event. *function_source<> the function that emits the event. *string_value<> any value that can qualify the event and provides useful information when reading the log.
fsm_journal_init()fsm_journal_initfsm.hfsm.hfsm_journal_initvoid fsm_journal_init (fsm_struct_journal * jj)init the journal Since2024-09
Parameters
fsm_journal_publication_request()fsm_journal_publication_requestfsm.hfsm.hfsm_journal_publication_requestvoid fsm_journal_publication_request ( )The fsm_journal_publication_request() is called only once, by main(), just after closing the app and before ending the program. This is to guarantee the chronological order of the events in the journal.The log is modified for each event but events can be send asynchronously. This is why the journal is only published once, before the end of "main()", Its chronological order is therefore guaranteed.src/journal.c/fsm_journal_publish() (called here) is the last function of the program to be executed.The fsm_struct_journal (gg_logs) is a static instance in this file. Therefore, all the functions that read or write it are in this file. This is to avoid uncontrolled operations on it.Since2024-08See alsosrc/main/main()src/journal/fsm_journal_publish() fsm_journal_publish()fsm_journal_publishfsm.hfsm.hfsm_journal_publishvoid fsm_journal_publish (fsm_struct_journal jj)publish all the logs today just print in the console TODO > in a file Since2024-09
