Try it

Install the binary:

cargo install dev_bestia_cargo_completion

Save definition for auto_completion in bash:

complete -C "dev_bestia_cargo_completion" cargo

Start typing cargo b and press tab.
It should auto-complete to cargo build.
Congratulation! You just used auto-completion :-)

bash auto completion

Auto-completion in Debian bash is a great tool. You type the first letters, press tab and the word is auto-completed.
Bash can call an executable binary to return the available words. So it can be written in Rust. This can produce even better results as known as dynamic auto-completion.
For my knowledge cargo does not have auto-completion yet. There are many plans. It can take some time.
I will build what I need now. Something simple. It doesn't need to be perfect.
This is a great blog:

complete, the Linux command

The Linux command complete adds auto_completion definitions to bash.
But it is only for the current session. If you want to make it persistent add it to you ~/.bashrc file. Or to some other file that runs commands on initialization of the bash.

# list the definitions
# delete a definition
complete -r cargo
# define a binary to auto-complete the command
complete -C "binary" command


I choose this long name for my crate, because cargo-completion is a hot topic. Sooner or later someone will build it - officially. This is why I added the prefix dev_bestia_, because my web domain is This way I have the guarantee of a unique name and leave the short name to the future official version.

cargo install cargo-auto

and then list the user-defined automation tasks with

cargo auto

You can change the definition for bash auto-completion to point to the compilation of this project in development. So you can easy test the auto-completion while developing it.

complete -C "/home/luciano/rustprojects/dev_bestia_cargo_completion/target/debug/dev_bestia_cargo_completion" cargo

open-source free and free as a beer

My open-source projects are free and free as a beer (MIT license).
I just love programming.
But I need also to drink. If you find my projects and tutorials helpful, please buy me a beer or two donating on my paypal. You know the price of a beer in your local bar ;-)
So I can drink a free beer for your health :-)
Na zdravje !
