# LogViewer
  - This is a general log viewer. It can parse the log files by providing regular expression configuration.
  - It supports several log format, such as spring-boot, Android, iOS, Visual studio, etc.
  -  ***Theoretically, this tool can be used to analyze any log format as long as you write regular expressions for it***.
 
# Function Point
  - 1. Config the regular expression(REGULAR) in ini configuration files, and then, set the result map in REGMAP, then the log files can be analyzed and displayed.
  - 2. Can filter the log according to machine / Process Id / Thread Id, log level, log text etc.
  - 3. Can calculate and get the elapse from the same thread of adjacent logs, thus it is able to identify the performance issue quickly.
  - 4. Can sort according to any column.
  - 5. Can open Visual Studio and identify the source code by double clicking the log item, only if there is a source filename and line number in logs.
  
# Log Configuration
  - 1.Sample file [Standard-SpringBoot.ini](x64/Release/Dsh-SpringBoot.ini) , the log file is [spring log demo](demos/dsh-springdemo.log), can get logs from multi servers by [distributed shell](https://github.com/fishjam/dsh) .
  - 2.COMMON 
    - REGULAR :  defines the regular expression for a log. [Regex Match Tracer](http://www.regex-match-tracer.com/) is recommended for writing and validating RegEx.
    - TIME_FORMAT : define the date and time format, now only support 4 format(ref sample).
    - OPEN_COMMAND: define the open source file and locate line position command in other IDE(just need support file and line), example: [Open *.go file in goland](x64/Release/GoLang.ini#L11)
  - 3.REGMAP : define the regular result and log part's correspondence. 
  - 4.LEVELMAP: define the log level's correspondence. 

# Use [Regex Match Tracer](http://www.regex-match-tracer.com/) to analyze and edit regular configurations
  - 1. Refer [Standard-SpringBoot.ini](https://github.com/fishjam/LogViewer/blob/master/x64/Release/Dsh-SpringBoot.ini) and [distributed spring log demo](https://github.com/fishjam/LogViewer/blob/master/demos/dsh-springdemo.log)

# TODO
 - [ ] Support pipe source, and so it can support real-time log(tail -f xxx | adb logcat | idevicelogsys | etc.)
