Support for dune shell completions for bash and zsh has just landed in the Dune Developer Preview!
Running the installer adds a snippet to
your shell config (e.g. ~/.bashrc) that installs a completion handler for dune.
The completion script was taken from
here, and that page has
some information about how the script was generated. Once it's installed the
completions will work any time dune is typed at the start of a command, so
you can still use the completions when running a version of Dune installed with
Opam or your system package manager after installing the Dune Developer Preview.
Currently only command completions are supported. So you can run:
$ dune c<TAB>
cache clean coq
...or:
$ dune build -<TAB>
--action-stderr-on-success
--action-stdout-on-success
--always-show-command-line
--auto-promote
--build-dir
--build-info
--cache
...
But if you run dune build <TAB> then it will still suggest
local files rather than build targets.
Try it out!
Getting started is easy:
$ curl -fsSL https://get.dune.build/install | sh
$ source ~/.bashrc # or: source ~/.zshrc
$ dune <TAB>
build
cache
clean
coq
describe
diagnostics
exec
...
