/*******************************************************************************
* ---------------------------
* Log Script für ioBroker zum Aufbereiten des Logs für Visualisierungen (vis), oder um
* auf Log-Ereignisse zu reagieren.
* ---------------------------
*
* Das Script nimmt jeden neuen Logeintrag des ioBrokers und wendet entsprechend gesetzte
* Filter an, um den Eintrag dann in den entsprechenden Datenpunkten dieses Scripts abzulegen.
* Es stehen auch JSON-Datenpunkte zur Verfügung, mit diesen kann im vis eine
* Tabelle ausgegeben werden (z.B. über das Widget 'basic - Table')-
*
* Aktuelle Version: https://github.com/Mic-M/iobroker.logfile-script
* Support: https://forum.iobroker.net/topic/13971/vorlage-log-datei-aufbereiten-f%C3%BCr-vis-javascript
* ---------------------------
* Change Log:
* 2.0.2 Mic + Changed certain functions to async to get rid of setTimout() and for the sake of better error handling.
* + startTailingProcess(): ensure the tailing starts if the file is present (wait to be created)
* 2.0.1a Mic Removed constant MERGE_LOGLINES_ACTIVE
* 2.0.0a Mic Major improvements and fixes:
* + Change from instant state update to schedule (STATE_UPDATE_SCHEDULE). The instant update, so once
* new log entries coming in, caused several issues (setting and getting state values (getState() and
* setState()) within <1ms simply does not work.
* - Fix issue with merging log lines
* + Moved global option MERGE_LOGLINES_ACTIVE to LOG_FILTER, for allowing turning on/off for each filter id.
* + Several other code improvements
* Note: For upgrading from previous version: replace script entirely, re-enter all your options,
* and delete all existing states prior to first activation of this script.
* ----------------------------------------------------------------------------------------------------
* 1.5.1 Mic - Set option MERGE_LOGLINES_ACTIVE to 'false' as default, as users reported issues. See
* https://forum.iobroker.net/post/288772 . Also option MERGE_LOGLINES_ACTIVE being marked as "experimental"
* in the comments. Requires further investigation.
* 1.5 Mic - Fix issue with option MERGE_LOGLINES_ACTIVE
* 1.4 Mic + New option MERGE_LOGLINES_TXT for an individual (e.g. localized) string other than 'entries'.
- Fix JSON span class closing
* 1.3 Mic + New option MERGE_LOGLINES_ACTIVE: Merge Loglines with same log message to only one line and adds leading
* '[123 entries]' to log message.
* 1.2 Mic - Fixed issue #6 (Button javascript.0.Log-Script.logXxxx.clearJSON not working reliably)
* 1.1 Mic + 1. 1.0x script seems to work reliable per user feedback and my own test, so pushing into 1.1 stable.
* + New state '.logMostRecent': provides just the most recent log entry to work with "on /
* subscribe" on this state and trigger actions accordingly.
* 1.02 alpha Mic - fix restarting at 0:00 (note: restarting is needed due to log file name change)
* 1.01 alpha Mic - fix: creating new file system log file only if not yet existing
* 1.00 alpha Mic + Entirely recoded to implement node-tail (https://github.com/lucagrulla/node-tail).
* ----------------------------------------------------------------------------------------------------
* 0.8.1 Mic - Fix: L_SORT_ORDER_DESC was not defined (renamed constant name was not changed in config)
* 0.8 Mic - Fix: Script caused a "file not found" error if executed right at or shortly after midnight.
* 0.7 Mic - Fix: States "...clearDateTime" will not get an initial date value on first script start,
* also fix for "on({id: ".
* 0.6 Mic + Put 0.5.1 BETA into stable
* + New option L_APPLY_CSS. If true, it will add <span class='log-info'>xxx</span>
* to each log string. 'log-info' for level info, 'log-error' for error, etc.
* This makes it easy to format a JSON table with CSS.
* 0.5.1 BETA Mic + New States "Clear JSON log ..." and "Clear JSON log - Date/Time ...".
* When the button "Clear JSON log" is pushed, the current date/time
* will be set into the date/time state. Once refreshed
* (per schedule in the script, e.g. after 2 minutes), the JSON
* will be cleaned and display just newer logs.
* Use Case: In vis, you can now add a button "clear log" or
* "Mark as read". If you hit the button, the log will be
* cleared and just new log items will be displayed.
* *** THIS IS STILL BEING TESTED *** therefore a beta release...
* 0.5 Mic + New parameter 'clean' to remove certain strings
* from the log line.
* + New parameter 'columns' for JSON output to specify which columns
* to be shown, and in which order.
* + New state "JSONcount" to have the number of log lines in state
* - Fixed a few issues
* 0.4 Mic - Bug fix: improved validation of log line consistency
* 0.3 Mic + Added filtering and blacklist
* - Several fixes
* 0.2 Mic - Bug fix: corrected wrong function name
* 0.1 Mic * Initial release

* --------------------------------------------------------------------------------------------------------------------------
* filter_any: Mindestens einer der gelisteten Begriffe muss enthalten sein. Leeres Array [] eingeben, falls hier filtern
* nicht gewünscht.
* --------------------------------------------------------------------------------------------------------------------------
* blacklist: Schwarze Liste: Wenn einer dieser Begriffe im Logeintrag enthalten ist, so wird der komplette Logeintrag
* nicht übernommen, egal was vorher in filter_all oder filter_any definiert ist.
* Mindestens 3 Zeichen erforderlich, sonst wird es nicht berücksichtigt.
* HINWEIS: BLACKLIST_GLOBAL wird vorher schon angewendet, hier kannst du einfach nur noch eine individuelle
* Blackliste pro id definieren.
* --------------------------------------------------------------------------------------------------------------------------
* clean: Der Log-Eintrag wird um diese Zeichenfolgen bereinigt, d.h. diese werden entfernt, aber die restliche Zeile
* bleibt bestehen. Z.B. um unerwünschte Zeichenfolgen zu entfernen oder Log-Ausgaben zu kürzen.
* --------------------------------------------------------------------------------------------------------------------------
* columns: Nur für JSON (für vis).
* Folgende Spalten gibt es: 'date','level','source','msg'. Hier können einzelne Spalten entfernt oder die
* Reihenfolge verändert werden. Bitte keine anderen Spalten eintragen, sondern nur 'date','level','source','msg'.
* --------------------------------------------------------------------------------------------------------------------------
* merge: Log-Einträge mit gleichem Text zusammenfassen. Beispiel:
* -----------------------------------------------------------------------------------
* 2019-08-17 20:00:00.335 - info: javascript.0 script.js.Wetter: Wetterdaten abrufen.

* 2019-08-17 20:30:00.335 - info: javascript.0 script.js.Wetter: Wetterdaten abrufen.
* -----------------------------------------------------------------------------------
* Daraus wird dann nur noch eine Logzeile mit letztem Datum/Uhrzeit und hinzufügen von "[3 Einträge]":
* -----------------------------------------------------------------------------------
