do not tag from hpp/cpp

LawranceXcl commented 1 year ago

when I input this command: ctags -R --kinds-c++=+p+l+x+c+d+e+f+g+m+n+s+t+u+v --fields=+liaS --extras=+q --languages=c++,c *, the tags file in current directory has no useful tags ,like this:

So what happens? thks

masatake commented 1 year ago

I have no idea. You specified too many options. What happens if you use the following command line?

$ cd /home/xcl/code/demo/test_main_modules/c++/code_musing
$ ctags --options=NONE -o - -R

Looks strange.

How about next one?

$ cd /home/xcl/code/demo/test_main_modules/c++/code_musing
$ ctags --options=NONE -o - --verbose main.cpp

LawranceXcl commented 1 year ago

@masatake not tags file generated yet, but it seems to be working!

masatake commented 1 year ago

tags is not generated. It is o.k. -o - option for printing tags to stdout. Could you try the following command lines?

$ cat > input.cpp <<EOF
int main(void) { return 0; }
EOF
$ ctags --options=NONE --verbose -o - input.cpp

In addition, I would like to see the output of:

$ cd /home/xcl/code/demo/test_main_modules/c++/code_musing
$ od -A x -t x1z -v < main.cpp | head -20

It seems that your main.cpp uses the newer syntax, maybe called C++-3000, that ctags doesn't support. The committee of C++-3000 accepts the binary-based compressed syntax.

About input.cpp, I don't understand what happens. I would like to see the output of:

$ cd /home/xcl/code/demo/test_main_modules/c++/code_musing
$ od -A x -t x1z -v < input.cpp

masatake commented 1 year ago

The file size of input.c is 4.1kb in your screenshot though it should be 29 bytes.

% ls -l input.cpp
-rw-r--r--. 1 jet jet 29 Apr 26 14:11 input.cpp

The file size of input.c is 4.1kb in your screenshot though it should be 29 bytes.

I don't think this is an issue of ctags.

The od output I expected is:

$ cat > input.cpp <<EOF             
int main(void) { return 0; }
EOF
$ od -A x -t x1z -v < input.cpp 
000000 69 6e 74 20 6d 61 69 6e 28 76 6f 69 64 29 20 7b  >int main(void) {<
000010 20 72 65 74 75 72 6e 20 30 3b 20 7d 0a           > return 0; }.<

On your system input.cpp has unexpected data:

000000 88 7d 1c b0 61 00 07 00 ad 7c 75 44 b5 56 17 a5  >.}..a....|uD.V..<

...

I don't understand what happens on your platform. The file system or your cat command looks broken to me. Anyway, this is nothing to do with ctags.
