I use opengrok, with default config to index golang source code, but there is no function list in the nagivate window,

I try to index with -o option:

./opengrok/bin/indexer.py \
    -a $OPENGROK/lib/opengrok.jar -- \
    -c /opt/ctags/bin/ctags \
    -o ctags.conf \
    -s $PWD/repo/src -d $PWD/repo/data -H -P -S -G \
    -W $PWD/configuration.xml \
    -U http://localhost:8080

and the ctags.conf is:

--langdef=golang
--langmap=golang:.go
--regex-golang=/func([ \t]+\([^)]+\))?[ \t]+([a-zA-Z0-9_]+)/\2/d,func/
--regex-golang=/var[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/d,var/
--regex-golang=/type[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/d,type/

but still doesn't work.

Any help? Thanks!

Contributor guide

Research direction
Inspect how OpenGrok invokes ctags and verify that the custom ctags configuration for Go is being used correctly. Check the indexing logs and the generated data to see if Go symbols are extracted.
