com.blockether.vis.ext.language-python.core — com.blockether/vis-language-python 0.1.4

vis-language-python — a managed Python REPL exposed through the generic language facade (repl_start / repl_eval / repl_stop). Activates only when the workspace looks like a Python project. The REPL is a subprocess on a project-aware interpreter (uv / poetry / .venv / python3), registered as a session resource so it shows in ctx + the footer and is stoppable by id.

py-repl-eval-fn clj

(py-repl-eval-fn env arg)

repl_eval handler for Python. Accepts a code string or {code, dir, timeout_ms}. AUTO-STARTS a REPL for the dir if none is running, then evaluates (globals persist across calls).

py-start-repl-fn clj

(py-start-repl-fn env op opts)

repl_start handler for Python. Positional op (default "start") + opts {dir, id}. Lifecycle: start / restart / stop / status. op arrives as a STRING from the model (strings-only boundary) — dispatch on it, no keyword minting.

py-test-fn clj

(py-test-fn env arg)

run_tests handler for Python. Two backends behind {runner}:

• "graalpy" (DEFAULT) — hermetic, stdlib-only. Discovers test_*.py / *_test.py under {paths} (default: tests/ if present, else the workspace root) and runs each in a TRUSTED GraalPy context via the built-in pytest shim. No project deps visible.
• "project" — shells the project interpreter's pytest (uv/poetry/.venv/python3 -m pytest <paths>) so installed test deps ARE visible. Aliases: {interpreter true}. Pass an opts map {runner, paths, dir} (a bare code string is not accepted).

register-repl-resource! clj

(register-repl-resource! session dir result & [id])

Mirror a managed Python REPL into the session resource registry (ctx + footer

• stop/restart by id). No-op without a session or a live pid.
