I have posted a question to the Xemacs NG about the fact that many
distros install a symlink to exuberant ctags that is named "etags,"
which has an incompatible command-line interface to real etags. Real
etags is surprisingly hard to get your hands on, without installing GNU
Emacs.
The upshot of this is that jtags, the script with JDE, doesn't work with
exuberant etags. After receiving a response on the NG which was "I found
a binary of the real etags in my emacs install", I decided to modify
jtags to support exub. etags.
The changes are:
# OLD:
# ${etags_dir}etags -l none -a -o ${java_dir}/TAGS \
# "--regex=$class1" "--regex=$class2" "--regex=$constructor"
# NEW:
# reflag='/b'
# ${etags_dir}etags --langdef=jtags --language-force=jtags -a -f
${java_dir}/TAGS \
# "--regex-jtags=$class1$reflag" "--regex-jtags=$class2$reflag"
"--regex-jtags=$constructor$reflag"
Really only three commands in the script are changed. But I don't know
what dialect of regex real etags expected, so I don't know if this works
properly.
Also, I don't know how well tags work in jtags/JDE. For instance, many
classes in one project I'm working on are singletons and have a static
"getInstance" method. find-tag in XEmacs can't seem to locate the proper
definition. Is this a problem with my conversion, with JDE, or with tag
support in Emacs for java?
Thanks,
Stuart
