NAME

       rusty-tags - creates ctags/etags for a cargo project

SYNOPSIS

       rusty-tags [options] tags_kind

DESCRIPTION

       rusty-tags  creates tags for source code navigation using ctags for a cargo(1) project, all of its direct
       and indirect dependencies and the Rust standard library.  It can be run anywhere inside a cargo  project.
       rusty-tags  creates  a  rusty-tags.vi  (if  tags_kind  is vi) or a rusty-tags.emacs file (if tags_kind is
       emacs) beside the Cargo.toml file.  Tags are also  generated  for  every  dependency.   If  a  dependency
       reexports  parts of its own dependencies, then these reexported parts are also contained in the tags file
       of the dependency.

       Tags for the standard library are created if the path to the Rust source  is  supplied  by  defining  the
       environment variable RUST_SRC_PATH.

OPTIONS

       -f, --force-recreate
              Forces the recreation of the tags of all dependencies and the Rust standard library.

       -h, --help
              Prints help information.

       -n, --num-threads=num
              Set the number of threads used for the tags creation (default: number of available physical cpus).

       -o, --omit-deps
              Do not generate tags for dependencies.

       -O, --output=filename
              Set  the  name  of  the  output  tags  file  (default:  rusty-tags.vi if tags_kind is vi or rusty-
              tags.emacs if tags_kind is emacs).

       -q, --quiet
              Do not output anything but errors.

       -s, --start-dir=dir
              Set the start  directory  for  the  search  of  the  Cargo.toml  file  (default:  current  working
              directory).

       -V, --version
              Prints version information.

       -v, --verbose
              Enable verbose output about all operations.

CONFIGURATION

   rusty-tags configuration
       rusty-tags reads the configuration file ~/.rusty-tags/config.toml.  It supports these settings:

       vi_tags
              The file name used for vi tags (default: rusty-tags.vi).

       emacs_tags
              The file name used for emacs tags (default: rusty-tags.emacs).

       ctags_exe
              The  name or path to the ctags(1) executable (default: ctags, exuberant-ctags, exctags, universal-
              ctags, uctags are tried in that order).

       ctags_options
              The options given to the ctags(1) executable (default: none).

   vim configuration
       To use the generated tag files with vim, add the following to your vimrc file:
           autocmd BufRead *.rs :setlocal tags=./rusty-tags.vi;/
           autocmd BufWritePost *.rs :silent! exec "!rusty-tags vi --quiet --start-dir=" . expand('%:p:h') . "&"
       | redraw!

       The  first line ensures that vim will automatically search for a rusty-tags.vi file upwards the directory
       hierarchy.  This setting is important if you want to jump to dependencies and the further jump  to  their
       dependencies.

       The second line ensures that your project's tag file gets updated if a file is written.

       If  you  have  set  the  path to the Rust source code in the RUST_SRC_PATH environment variable, use this
       setting instead:
           autocmd BufRead *.rs :setlocal tags=./rusty-tags.vi;/,$RUST_SRC_PATH/rusty-tags.vi

ENVIRONMENT

       RUST_SRC_PATH
              The path to the source code of the Rust standard library to generate tags for.
