Navi

To instal navi¹ on Linux you can use

$ bash <(curl -sL https://raw.githubusercontent.com/denisidoro/navi/master/scripts/install)

When installing navi on Ubuntu 20 you will get the error

invalid preview window layout: up:2:nohidden
invalid preview window layout: up:2:nohidden
invalid preview window layout: up:2:nohidden

This is very likely due to the fact that the fzf² version is too old (perhaps 0.20).

To upgrade to the latest version of fzf use:

$ git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
$ ~/.fzf/install

Importing cheatsheets

You can import cheatsheets from any git repository that includes .cheat files:

$ navi repo add https://github.com/ruivieira/cheatsheets

External variables

It is possible to populate variables with external data in navi. To do so, specify how fzf will extract the data. For instance, the command

docker stop <container_id>

will stop the container <container_id>, which we could extract from the output of

$ docker ps

We can then specify docker ps and the input of docker stop and instruct fzf on the data’s format. For instance, here (line 2) we say that from the command of docker ps we should extract the first column, delimited by spaces and remove the first line, since it is the header.

docker stop <container_id>
$ container_id: docker ps --- --column 1 --header-lines 1 --delimiter '\s\s+'
