eval.hx

Evaluates Steel code against the live editor engine (via the eval-string builtin) and routes results to a dedicated *hx-eval* scratch buffer, in the style of nrepl.hx⁠.

Evaluation is synchronous and runs on the editor’s own engine, so evaluated code can call any helix/* function and see prior definitions.

Note that evaluated code shares the global namespace and can shadow bindings.

Demo

Commands

• :hx-eval-selection - Evaluate the primary selection.
• :hx-eval-buffer - Evaluate the entire buffer.
• :hx-eval-multiple-selections - Evaluate every selection in sequence.
• :hx-eval-prompt - Prompt for an expression and evaluate it.

Results are appended to the *hx-eval* buffer in REPL format: a repl:N:> prompt, the value, or a commented error block.

Install

forge pkg install --git https://github.com/waddie/eval.hx
