Java lines of code to Java statements

locs-to-stms is an utility Java program that parses java files to extract the set of lines of code that are part of the same Java statement.

Considering the following snippet of code from JFreeChart, class org.jfree.chart.renderer.category.LineAndShapeRenderer:

762.  if (this.useSeriesOffset) {
763.      x0 = domainAxis.getCategorySeriesMiddle(
764.              column - 1, dataset.getColumnCount(),
765.              visibleRow, visibleRowCount,
766.              this.itemMargin, dataArea,
767.              plot.getDomainAxisEdge());
768.  }

It can be seen there are 6 lines of code, but only 2 statements (as lines 763-767 are part of the same statement). So, locs-to-stms reads a list of java files and prints to a file, information of each java statement. Each row of the file contains two columns: First column represents a statement, and the second column represents a line of code that is part of the statement. For example:

...
org/jfree/chart/renderer/category/LineAndShapeRenderer.java#763:org/jfree/chart/renderer/category/LineAndShapeRenderer.java#764
org/jfree/chart/renderer/category/LineAndShapeRenderer.java#763:org/jfree/chart/renderer/category/LineAndShapeRenderer.java#765
org/jfree/chart/renderer/category/LineAndShapeRenderer.java#763:org/jfree/chart/renderer/category/LineAndShapeRenderer.java#766
org/jfree/chart/renderer/category/LineAndShapeRenderer.java#763:org/jfree/chart/renderer/category/LineAndShapeRenderer.java#767
...

I.e., lines #764, #765, #766, #767 are part of statement #763.

How to compile it?

mvn clean package

How to use it?

java -jar locs-to-stms-<version>-jar-with-dependencies.jar locstostms \
  <classes> ...
  --srcDirs <dir>
  [--outputFile <file>]

Where <classes> is the list of classes to parse, --srcDirs is the source directory (more than one can be defined), --outputFile is the file to which the output of locs-to-stms is written.

For example:

java -jar locs-to-stms-0.0.1-jar-with-dependencies.jar locstostms
  org.jfree.chart.renderer.category.LineAndShapeRenderer \
  --srcDirs src/main/java \
  --outputFile locstostms.txt
