A short crash example: Lets pretend your top Java directory is
~/source/my_java_project
and that you like to change the class name DontGrokTags to GrokTags.
Please do the following:
M-! cd ~/source/my_java_project; find . -name "*.java" -print | etags - RET
M-x select-tags-table RET ~/source/my_java_project RET
M-x tags-query-replace RET \<DontGrokTags\> RET GrokTags RET
... and answer as you please, just like for query-replace (M-%),
i.e. do a couple of "y" until that you are confident that the changes
done are correct, then "!" to do the rest of the files. End with a
"C-x s" to save all those changed files.
Explanation:
o The first line above does a shell command where you run the
external program "etags" in a nifty "find" command (taken from
the info pages), to make a TAGS file, situated at your top Java
directory.
o The second line tells emacs to use that particullar TAGS file
for further tags command.
o The third line does the magic name change. Note: I recommend to
use the regexp meta characters "start of word" (\<) and "end of
word" (\>) to avoid conversion of other names that use
DontGrokTags as part of their names, e.g. DontGrokTagsAtAll will
not be converted by the above method.
The final thing todo is to change the filename DontGrokTags.java. You
may want to do "M-x vc-rename-file RET ... RET" if your file is under
CVS/RCS control.
Read more about tags in info by doing "C-h i g (emacs)Tags RET", and
more about regexps and searching in "C-h i g (emacs)Search RET".
