When maintaining Rust projects, this plugin helps with updating the dependencies in Cargo.toml files. It uses the crates.io API to get all available versions of a crate and caches them.

curl needs to be installed.

• Insert completion

  If the cursor is on a version requirement and in insert mode, use <c-x><c-u> (hold Ctrl and hit x then u) to open a completion menu with all available versions (see :h i_CTRL-X_CTRL-U).

• :CratesUp

  Update the current dependency to the latest non-prerelease version.

• :CratesToggle

  For each dependency that is out-of-date, indicate the latest version as virtual text after the end of the line. Use it again to remove all indicators. This is a Nvim-only feature.

  Customize the colors of the indicators like this:

  highlight Crates ctermfg=green ctermbg=NONE cterm=NONE
  " or link it to another highlight group
  highlight link Crates WarningMsg

  Use :verb CratesToggle to see debug messages.

Inspired by serayuzgur/crates.

Happy 🦀 everyone!

Automatically run :CratesToggle when opening a Cargo.toml file:

if has('nvim')
  autocmd BufRead Cargo.toml call crates#toggle()
endif
