Strict Paredit
Classic, Emacs Paredit-like Structural editing and navigation for Common Lisp, Clojure and Scheme.
This is a Paredit extension for Visual Studio Code. It is a thin wrapper around paredit.js. You find it inside Code's extension view and on the Marketplace.
Commands
Note: You can choose to disable all default key bindings by configuring paredit.defaultKeyMap to none. (Then you probably also want to register your own shortcuts for the commands you often use. see ets/keys.json for example). By default the strict mode map is used. Below commands work in both strict mode and original mode.
If you are new to Paredit, below shortcut in bond text is a small but very frequently used set of commands that helps in 95% of the time. I hightly recommend you memorize them to be efficient.
Navigation

|---|---|
| ctrl+right | Forward Sexp |
| ctrl+left | Backward Sexp |
| ctrl+down | Forward Down Sexp |
| ctrl+up | Backward Up Sexp |
| ctrl+alt+right | Close List |
Selecting
| Default keybinding | Action |
|---|---|
| ctrl+w | Expand Selection |
| ctrl+shift+w | Shrink Selection |
| ctrl+alt+w | Select Current Top Level Form |
Editing
| Default keybinding | Action |
|---|---|
| ctrl+alt+. | Slurp Forward |
| ctrl+alt+< | Slurp Backward |
| ctrl+alt+, | Barf Forward |
| ctrl+alt+> | Barf Backward |
| ctrl+alt+s | Splice |
| ctrl+alt+shift+s | Split Sexp |
| ctrl+delete | Kill Sexp Forward |
| ctrl+shift+backspace (on Mac) | Kill Sexp Forward |
| ctrl+backspace | Kill Sexp Backward |
| ctrl+alt+down | Splice & Kill Forward |
| ctrl+alt+up | Splice & Kill Backward |
| ctrl+alt+9, Ctrl+alt+( | Wrap Around () |
| ctrl+alt+[ | Wrap Around [] |
| ctrl+alt+{ | Wrap Around {} |
| ctrl+alt+i | Indent |
| ctrl+alt+t | Transpose |
You can also select the sexp with ctrl+w then wrap around by typing (, [ or { and delete it with backsapce
Strict only keybinding
| Strict mode keybinding | Action |
|---|---|
| backspace | Delete Backward or move left if at )]} |
| delete | Delete Forward or move right if at )]} |
| shift+backspace (on Mac) | Delete Forward or move right if at )]} |
| ctrl+alt+backspace | Force Delete Backward |
| ctrl+alt+delete | Force Delete Forward |
| alt+shift+backspace (on Mac) | Force Delete Forward |
NB: Strict mode is enabled by default. The backspace and delete keys won't let you remove parentheses or brackets so they become unbalanced. To force a delete anyway, use the supplied commands for that. Strict mode can be switched on/off by configuring paredit.defaultKeyMap to strict/original.

|---|---|
| ctrl+alt+c ctrl+right | Copy Forward Sexp |
| ctrl+alt+c ctrl+left | Copy Backward Sexp |
| ctrl+alt+c ctrl+down | Copy Forward Down Sexp |
| ctrl+alt+c ctrl+up | Copy Backward Up Sexp |
| ctrl+alt+c ctrl+alt+right | Copy Close List |
Cutting
| Default keybinding | Action |
|---|---|
| ctrl+alt+x ctrl+right | Cut Forward Sexp |
| ctrl+alt+x ctrl+left | Cut Backward Sexp |

Maintainers
This project is forked from https://github.com/BetterThanTomorrow/calva-paredit. Original one is maintained by author Peter Strömberg as part of project calva, https://github.com/BetterThanTomorrow/calva
I maintain this fork with the following stress:
- Tweak to keep the joy of original Emacs paredit, especially how delete, back parens and navigation works.
- Make it useful for Common Lisp and Scheme developers (Assume there's no one use vscode to code Emacs Lisp :)
