Implementation according to discussion based on vladak #4610
I've verified that the include 'file' are clickable.

There should be a test file that actually uses these newly supported properties. The lexer should be run on the file and compare the xref to golden stored output - see https://github.com/oracle/opengrok/tree/master/opengrok-indexer/src/test/resources/analysis/fortran

Can you give me more info on this one ?

The Fortran analysis tests are under https://github.com/oracle/opengrok/tree/master/opengrok-indexer/src/test/java/org/opengrok/indexer/analysis/fortran

From there, the

opengrok/opengrok-indexer/src/test/java/org/opengrok/indexer/analysis/fortran/FortranXrefTest.java

Lines 39 to 44 in f79db40

	void sampleTest() throws IOException {
	writeAndCompare(new FortranAnalyzerFactory(),
	"analysis/fortran/sample.f",
	"analysis/fortran/sample_xref.html",
	readTagsFromResource("analysis/fortran/sampletags"), 28);
	}

is the most relevant for this change. It runs the lexer on the https://github.com/oracle/opengrok/blob/master/opengrok-indexer/src/test/resources/analysis/fortran/sample.f file and compares the result with the golden file https://github.com/oracle/opengrok/blob/master/opengrok-indexer/src/test/resources/analysis/fortran/sample_xref.html

For this case, I'd recommend creating new Fortran code under https://github.com/oracle/opengrok/tree/master/opengrok-indexer/src/test/resources/analysis/fortran with its expected output and adding a new test (or better parametrize the pre-existing one referenced above). The golden file (expected result) can be obtained e.g. by running the indexer on the sample file or by extracting the data from debugger when stepping through the newly added test case.

@vladak Made the changes suggested by you.

[vladak]

fix the onNonSymbolMatched() arguments

[navinp0304]

fix the onNonSymbolMatched() arguments

You mean this 84c1728 ?

[vladak]

yep, something like this (modulo the missing white space around binary operators)

@vladak
Do you have any scripts like indent,style oe clang-format and the settings I can use ?
Or is it just this ?
onNonSymbolMatched(cmatch.substring(cmatch.length()-1,1)

[vladak]

The style check is run during Maven build of the project using the maven-checkstyle-plugin (e.g. mvn -DskipTests=true verify), the rules are stored in https://github.com/oracle/opengrok/tree/master/dev/checkstyle

Actually, looking at the rules and checkstyle.org documentation I am not sure it can be enforced. Just surround the binary operators with spaces.

Thanks !
