Using it for shell scripting

For a real world scenario example, please check this blog post.

Let's say you want to write a bash script that, among other things, asks the user to write the name of a git branch that should be checked out.

If you already have the cheatsheet above, then you could write the following in your script:

navi --query "change branch" --best-match

navi will ask the user to fill all arguments needed.

If you want to set the <branch> beforehand in your script:

branch="master" navi --query "change branch" --best-match

• no interactive input will be shown
• the value for <branch> will be exactly the one passed as argument

If you want to filter some results for <branch>:

branch__query="master" navi --query "change branch" --best-match

• an interactive input will be shown, unless a single entry is autoselected
• the value for <branch> will be the one selected

If you want to select the best match for <branch>:

branch__best="master" navi --query "change branch" --best-match

• no interactive input will be shown
• the value for <branch> will be the one that best matches the one passed as argument
