Class BuildDependencyGenerator
java.lang.Object
org.antlr.v4.tool.BuildDependencyGenerator
Given a grammar file, show the dependencies on .tokens etc...
Using ST, emit a simple "make compatible" list of dependencies.
For example, combined grammar T.g (no token import) generates:
TParser.java : T.g
T.tokens : T.g
TLexer.java : T.g
If we are using the listener pattern (-listener on the command line)
then we add:
TListener.java : T.g
TBaseListener.java : T.g
If we are using the visitor pattern (-visitor on the command line)
then we add:
TVisitor.java : T.g
TBaseVisitor.java : T.g
If "-lib libdir" is used on command-line with -depend and option
tokenVocab=A in grammar, then include the path like this:
T.g: libdir/A.tokens
Pay attention to -o as well:
outputdir/TParser.java : T.g
So this output shows what the grammar depends on *and* what it generates.
Operate on one grammar file at a time. If given a list of .g on the
command-line with -depend, just emit the dependencies. The grammars
may depend on each other, but the order doesn't matter. Build tools,
reading in this output, will know how to organize it.
This code was obvious until I removed redundant "./" on front of files
and had to escape spaces in filenames :(
I literally copied from v3 so might be slightly inconsistent with the
v4 code base.
