E259: not find ***

[ltang666]

Want to find the definition, but ctags return E259. How can I debug it?

The command line you used to run ctags:

ctags -f "/.cache/tags/data.tags.temp" "-
-options=/.vim/plugged/vim-gutentags/res/ctags_recursive.options"  --fields=+niazS --extra=+q --c++-kinds
=+px --c-kinds=+px --output-format=e-ctags "/search/z"

What is E259?

Are you talking about the exit status of the ctags process?
If the VIM reports #529, I have no idea.

It seems that E259 is reported by VIM.

Want to find the definition, but ctags return E259. How can I debug it?

What you have to do for debugging ctags is find a way to explain the bug of ctags without VIM.

The definition you are looking for is included in tags output of ctags?
If the answer is yes, I would like to say ctags works fine. You cannot debug ctags because ctags has no but about the input files and the definition you are looking for.

If you cannot find the definition in the tags file, there can be a bug of ctags.
You must identify the input file name where the definition is. If the programming language used in the input file is not supported in ctags, the debugging is not needed. Instead, you have to write a new parser. We don't call "writing new parser" is "developping".
