xtc.tree.LineupPrinter
| LineupPrinter | | public class LineupPrinter extends Printer (Code) | | A printer that guarantees that each Node is printed at the exact
file, line, and column specified by its location. Where necessary, this
printer prints line markers (similar to those used by the C preprocessor:
# line "file"
Reproducing exact source locations helps downstream tools track symbolic
information for error messages, debugging, and exception backtraces. Even
though this printer makes a best effort to print nodes without locations
nicely, experience shows that the generated code is usually harder to read
for humans (less "pretty") than with the superclass xtc.tree.Printer.

Line number specified by the last node that had a location. | | protected String | markedFile
File name specified by the last emitted line marker. | | protected long | markedLine
Line number specified by the last emitted line marker. | | protected long | markedPhysical
Line number in the actual output after the last emitted line marker. | | protected boolean | showFilePaths
