The 1.2.0 release contains some cool new features and some bug fixes.

New features since 1.1.0 include:

  • Reload is automatically done whenever a script file, requirements.txt or yaml file below the pyscript folder is modified, created, renamed or deleted, or a directory is renamed, created or deleted; see #74. This uses the watchdog module which is already used by the folder_watcher integration.
  • New functions task.create, task.current_task, task.cancel, task.name2id, task.wait, task.add_done_callback, task.remove_done_callback allow new background (async) tasks to be created, canceled, waited on, and completion callbacks to be added or deleted. Proposed by @dlashua and @valsr; see #112, #130, #143, #144.
  • Added support for now to @time_trigger time specifications, which means the current date and time when the trigger was first evaluated (eg, at startup or when created as an inner function or closure), and remains fixed for the lifetime of the trigger. This allows time triggers of the form once(now + 5min) or period(now, 1hr). Proposed by @wsw70; see #139.
  • Function decorators are now supported. However, the existing trigger decorators are still hardcoded (ie, not available as function calls), and decorators on classes are not yet supported. First implementation by @dlashua; see #43.
  • New function decorator @pyscript_compile compiles a native Python function inside pyscript, which is helpful if you need a regular function (by default all pyscript functions are async coroutines) for task.executor, functions like map or filter, callbacks, or if you have code you want to run at compiled speed (see #71). The function body can't contain any pyscript-specific features, and closure of variables for an inner function that uses @pyscript.compile won't work either, since in pyscript local variables with scope binding are objects, not their native types. Proposed by @dlashua; see #71.
  • A new variable pyscript.app_config is available in the global address space of an app's main file (ie, apps/YOUR_APP.py or apps/YOUR_APP/__init__.py) and is set to the YAML configuration for your app (ie, pyscript.config["apps"][YOUR_APP]). The latter is still available, but is deprecated and the apps entry in pyscript.config will be removed in a future release to prevent wayward applications from seeing configuration settings for other apps.
  • Updated croniter to 1.0.2.
  • Updated docs to explain how secret parameter values can be stored and retrieved from yaml configuration, by @exponentactivity; see #124.
  • Report parsing errors on invalid @time_active arguments; by @dlashua; see #119.
  • task.executor raises an exception when called with a pyscript function.

Breaking changes since 1.1.0 include:

None. However, the use of pyscript.config["apps"][YOUR_APP] to get application configuration is still available but now deprecated. The apps entry in pyscript.config will be removed in a future release. This is to prevent wayward applications from seeing configuration settings for other apps. The new pyscript.app_config variable should be used instead - it is set to pyscript.config["apps"][YOUR_APP] for each app.

Bug fixes since 1.1.0 include:

  • Fixed shutdown trigger for case where it calls task.unique(); reported by @dlashua (#117).
  • Duplicate @service function definitions (ie, with the same name) now correctly register the service, reported by @wsw70; see #121.
  • Added error message for invalid @time_active argument, by @dlashua; see #118.
  • The scripts subdirectory is now recursively traversed for requirements.txt files.
  • Inner functions and classes (defined inside a function) are added to global symbol table if declared as global.
  • Reload all scripts if global settings allow_all_imports or hass_is_global change; see #74.
  • Methods bound to class instances use weakrefs so that __del__ works; reported by @dlashua; see #146.
  • Pyscript user-defined functions (which are all async) can now be called from native python async code; see #137.
  • Internals that call open() now set encoding=utf-8 so Windows platforms use the correct encoding; see #145.
  • On Windows, python is missing locale.nl_langinfo, which caused startup to fail when the locale-specific days of week were extracted. Now the days of week in time trigger expressions are available on Windows, but only in English; see #145.
  • task.name2id() raises NameError if task name is undefined. Also added kwargs to task.wait().
  • Added "scripts/**" to REQUIREMENTS_PATHS, so deeper directories are searched.
  • Fixed typos in task reaper code, by @dlashua; see #116.
  • Fixed exception on invalid service call positional arguments, reported by @huonw; see #131.

Thanks to @dlashua for proposing, implementing and testing several new features in this release.

Enjoy!
