[Ctags] Tagging of Emacs backup files

[Niels S. O. <ns...@ma...>]

Hi,

When I tag my sources, Emacs backup files are also processed. How can I
exclude them from being tagged?

I normally run ctags recursively on my C++ source root like this:

    ctags -e -R --c-types=+C --file-tags=yes --totals --lang=c++ mydir

The resulting tags file will contain tags for both:

  foo.cpp
  foo.cpp~

But .cpp~ is not part of the default C++ language map:

  ctags -V
  Installing option defaults
      Setting default header extensions: h, H, hh, hpp, hxx, h++, inc, def
      Setting default asm map: asm, s, S
      Setting default AWK map: awk, gawk, mawk
      Setting default BETA map: bet
      Setting default C map: c
      Setting default C++ map: c++, cc, cpp, cxx, h, hh, hpp, hxx, h++, C, H
      Setting default COBOL map: cob, COB
      Setting default Eiffel map: e
      Setting default Fortran map: f, for, ftn, f77, f90, f95, F, FOR, FTN, F77, F90, F95
      Setting default Java map: java
      Setting default Lisp map: cl, clisp, el, l, lisp, lsp, ml
      Setting default Perl map: pl, pm, perl
      Setting default Python map: py, python
      Setting default Scheme map: SCM, SM, sch, scheme, scm, sm
      Setting default sh map: sh, SH, bsh, bash, ksh
      Setting default Tcl map: tcl, wish
      Setting default Vim map: vim


I'm running:

  Exuberant Ctags 4.0.3
  NT4.0 SP6a
