dsh-code-runner

Opening a code file in DSH better-sidebar and wanting to see output instantly usually means switching to a terminal, typing the right command, and waiting. dsh-code-runner collapses that ritual into a single button. Inspired by the vscode-code-runner executor model, it injects a play button into the editor header: click it and the file is auto-saved, an executor is matched by extension, and the command runs in the bottom terminal panel without leaving the current view.

Stability is built in. Commands travel through the built-in WebSocket terminal channel, and the connection stays open after sending so long-running tasks are never killed by the host reconnect logic. When the bottom panel is unavailable, execution falls back to the right-side terminal. The bundled executor covers dozens of languages including JavaScript, Python, C, C++, Go, Rust, Shell, Lua, Haskell, and more, with the mapping consolidated in one file for easy extension. At install time the script auto-detects and pulls in the better-sidebar base dependency. The plugin never modifies DSH source code, registers no extra tools, and leaves the session context untouched.

For developers who treat better-sidebar as a daily coding workbench and want to run scripts or compile snippets without breaking out of the chat flow, this is a small but meaningful upgrade. Open any runnable file from the tree, and that little play button in the editor header is the only interaction you need.
