Logtrail Source Analyzer Java

Source Analyzer for Java Language. Parse the source code to analyze and extract logger statements into JSON with configured context.

Usage

java -jar source-analyzer.jar -src project/src -context FQN -output patterns.json

The context can be SIMPLE_NAME (class name containing the logger statement) or FQN (includes package name)

TODO

The parser for now is hard coded for SLF4J API. Has following shortcomings:

• Makes assumption that the logger context is always Class(SIMPLE_NAME) / Package(FQN) containing the logger statement. Cannot handle cases where the logger context is hard-coded string (LoggerFactor.getLogger("custom-context")) or present in base class. \When the analyzer is not able to resolve the logger declaration to current class, it will map the log statement to default-context.
• The reg-ex patterns only matches variable values with non-whitespace chars. e.g. in the below logger statement if username evaluates to John Smith only John will be matched.

LOG.info("User {} is logged in", username)

• Following logger statements will be matched:

 LOG.info("User logged in");
 LOG.info("User {} is logged in",username);
 LOG.info("User {} is logged in from machine {}",username,machine);
 LOG.info("User " + username + " is logged in from machine " + machine);
