$ cargo install rusty-tags
The build binary will be located at
rusty-tags vi or
rusty-tags emacs anywhere inside
of the cargo project should just work.
After its run a
rusty-tags.vi / rusty-tags.emacs file should be beside of the
Additionally every dependency gets a tags file at its source directory, so jumping further to its dependencies is possible.
If a dependency reexports parts of its own dependencies, then these reexported parts are also contained in the tags file of the dependency.
Rust Standard Library Support
Tags for the standard library are created if the rust source is supplied by
defining the environment variable
If you're using rustup you can get the rust source of the currently used compiler version by calling:
$ rustup component add rust-src
And then setting
RUST_SRC_PATH inside of e.g.
$ export RUST_SRC_PATH=$(rustc --print sysroot)/lib/rustlib/src/rust/src/
rustup by getting the rust source by yourself:
$ git clone https://github.com/rust-lang/rust.git /home/you/rust $ cd /home/you/rust $ git checkout stable $ export RUST_SRC_PATH=/home/you/rust/src/ # should be defined in your ~/.bashrc
rustup is the recommended way, because the you will automatically get
the correct standard library tags of the currently used compiler version.
The current supported configuration at
~/.rusty-tags/config.toml (defaults displayed):
# the file name used for vi tags vi_tags = "rusty-tags.vi" # the file name used for emacs tags emacs_tags = "rusty-tags.emacs"
Put this into your
autocmd BufRead *.rs :setlocal tags=./rusty-tags.vi;/ autocmd BufWrite *.rs :silent! exec "!rusty-tags vi --quiet --start-dir=" . expand('%:p:h') . "&"
The first line (only supported by vim >= 7.4) ensures that vim will
automatically search for a
rusty-tags.vi file upwards the directory hierarchy.
This tags setting is important if you want to jump to dependencies and then further jump to theirs dependencies.
The second line ensures that your projects tag file gets updated if a file is written.
If you've supplied the rust source code by defining
autocmd BufRead *.rs :setlocal tags=./rusty-tags.vi;/,$RUST_SRC_PATH/rusty-tags.vi
The plugin CTags uses vi style tags, so
rusty-tags vi should work.
By default it expects tag files with the name
.tags, which can be set
vi_tags = ".tags" inside of
Mac OS users may encounter problems with the execution of
ctags because the shipped version
of this program does not support the recursive flag. See this posting
for how to install a working version with homebrew.
