Quirks

Here’s a shocker for ya’: Calva isn’t perfect. 😄

There are quirks and things that flat out do not work. We’ll try to collect info about such things here, providing workarounds when available (or, rather, known to us).

Test features not available with ClojureScript

Currently cider-nrepl does not provide its test functionality for ClojureScript code. Please consider contributing to fixing that.

Using with Parinfer

Calva defaults to formatting as you type. If you use Parinfer this creates a conflict, since it auto-indents your code. If you want to use Parinfer you’ll have to tell Calva not to do auto-formatting by disabling calva.fmt.formatAsYouType.

However, with VS Code and Calva it is probably better to learn to use Paredit’s slurp and barf and generally use Calva’s automatic formatting.

MacOS and the Slurp and Barf Keyboard Shortcuts

To make slurping and barfing forward really easy to perform they are bound to ctrl+right and ctrl+left, respectively. However on MacOS those shortcuts are sometimes bound by Mission Control, causing the Calva shortcuts to not work. One way to solve it is to disable the shortcuts in System Preferences -> Keyboard -> Shortcuts:
