- [inputs/outputs](https://app.metapage.io/dion/py.mtfm.io-test/view)
- Run python code entire in the browser, and connect to other metaframes
- Edit python code directly in the frame
- All code and configuration is stored in the URL
- shareable and durable
## Configuration + Inputs/Outputs
There are two (metaframe) modes (set in ⚙️ Options):
1. `✅ Re-run python code on new inputs`: Anytime new metaframe inputs arrive, restart the script. Any files in `/outputs` are copied and send as metaframe outputs. If the file suffix is recognized (e.g. `.js`, `.json`, `.py`) then it will be sent as a string (or directly as JSON if ending in `.json`), otherwise it will be send as an ArrayBuffer.
- Inputs **are** copied as files
2. `❌ Re-run python code on new inputs`: Run the script once, the script is responsible for listening to inputs by calling the metaframe object (see examples below).
- Inputs are **not** copied as files
The use case of copying inputs and outputs as files but **not* re-running seems counterintuitive to me, let me know if you have this use case: https://github.com/metapages/metaframe-py/issues
## Useful code snippets
### Get the (current) metaframe inputs
```python
from js import metaframe
inputs = metaframe.getInputs().as_object_map()
for key in inputs:
print(key)
print(inputs[key])
# Do something with the value
```
### Listen to new metaframe inputs
```python
from pyodide.ffi import create_proxy
from js import metaframe
def onInputs(*args):
print('got inputs in python:')
inputs = args[0].as_object_map()
for key in inputs:
print(key)
onInputsProxy = create_proxy(onInputs)
disposer = metaframe.onInputs(onInputsProxy)
# Call the disposer via the scriptUnload described next below
```
### Unload/cleanup/dispose
When iterating/editing, the python script is repeatedly run in the `pyiodide` object. This can cause problems if proxied `js <-> python` objects are not properly disposed.
Before every new python script execution, (in javascript) if a `window.scriptUnload` script exists, it is called. This is where you put your cleanup:
```python
from pyodide.ffi import create_proxy
from js import window
# Put this at the end of your script:
def scriptUnload(*args):
print('unloading from python')
# Call your cleanup code here
proxy_scriptUnload = create_proxy(scriptUnload)
window.scriptUnload = proxy_scriptUnload
```
### Logging to the main div
Some convenience functions:
```py
# log is the same as logStderr
from js import log, logStdout, logStderr
# These functions only take a single string, no fancy formatting or multiple arguments
log("some string")
logStdout("some string")
logStderr("some error")
```
