1 | # pyscript-local-runtime
2 |
3 | This repository provides a framework for running PyScript and all its runtime dependencies locally e.g. to create a Chrome extension using Python, or an offline web app using PyScript without relying on internet access.
4 |
5 | PyScript and its dependency Pyodide continue to evolve but this demo is frozen at Pyodide v0.21.3. You're strongly advised to check out the [latest version of PyScript](https://pyscript.net/) and there are numerous PyScript tutorials online for learning more about its capabilities - that's not the focus of this Demo!
6 |
7 | All the files you need to run PyScript (at v0.21.3) are in the `/runtime` directory and you can also download them on POSIX using wget...
8 | ```shell
9 | cd runtime
10 | source setup.sh
11 | ```
12 |
13 | or on Windows using the helper script supplied:
14 | ```
15 | cd runtime
16 | python setup.py
17 | ```
18 |
19 | ## **EXAMPLE CHROME EXTENSION**
20 | 
21 |
22 | This example Chrome Extension launches a Popup when clicked, renders the time using Python's `datetime` module, and provides a Python REPL session for you to play with directly inside the extension.
23 |
24 | To use this extension directly, first clone it to your local machine then
25 | [follow this tutorial](https://medium.com/p/6c6b0e2e1573) to load the unpacked extension into Chrome and pin it to your Extensions toolbar.
26 |
27 | * Icons are in the `/icons` folder.
28 | * PyScript/Pyodide files to run this offline or as part of an extension are in the `/runtime` folder.
29 | * Other magic required for Chrome to recognise this as an extension is in `manifest.json`.
30 | * `popup.css` is a super-simple Cascading Style Sheet which defines the appearance of the Popup - in this case simply the width, height, and background colour.
31 | * `popup.html` defines the page content of the Popup. It includes some simple boiler-plate HTML as well as some examples of Python code which runs under the tags `` and/or ``.
32 | * `popup.html` must include a `` block as follows:
33 |
34 | ```html
35 |
36 | [[runtimes]]
37 | src = "runtime/pyodide.js"
38 | name = "pyodide-0.21.3"
39 | lang = "python"
40 |
41 | ```
42 |
43 | * `popup.html` must also include two lines to load PyScript and its default stylesheet into the extension:
44 |
45 | ```html
46 |
47 |
48 | ```
49 |
50 | Further information about getting started with Chrome Extensions is available [here](https://developer.chrome.com/docs/extensions/mv3/getstarted/).
51 |
52 | All the best,
53 | Pete

1224 | extension of filename. In particular we decide the file format as

1226 |
1227 | 1. If format is present, we use that.

1234 | extract_dir

1242 | extract_dir.

2065 |
2066 | Specifies what should be returned, must be one of ``'last_expr'``,
2067 | ``'last_expr_or_assign'`` or ``'none'``. On other values an exception is

2076 | Specifies whether a trailing semicolon should suppress the result or not.

2083 |
2084 | mode : ``str``
2085 |
2086 | The "mode" to compile in. One of ``"exec"``, ``"single"``, or ``"eval"``. Defaults

2530 |
2531 | ``default_converter`` if present will be invoked whenever Pyodide does

2533 | If ``default_converter`` raises an error, the error will be allowed to
2534 | propagate. Otherwise, the object returned will be used as the
2535 | conversion. ``default_converter`` takes three arguments. The first
2536 | argument is the value to be converted.
2537 |
2538 | Here are a couple examples of converter functions. In addition to the
2539 | normal conversions, convert ``Date`` to ``datetime``:
2540 |
2541 | .. code-block:: python
2542 |
2543 | from datetime import datetime
2544 | def default_converter(value, _ignored1, _ignored2):
2545 | if value.constructor.name == "Date":
2546 | return datetime.fromtimestamp(d.valueOf()/1000)
2547 | return value
2548 |
2549 | Don't create any JsProxies, require a complete conversion or raise an error:

2551 | .. code-block:: python
2552 |
2553 | def default_converter(_value, _ignored1, _ignored2):
2554 | raise Exception("Failed to completely convert object")
2555 |
2556 | The second and third arguments are only needed for converting
2557 | containers. The second argument is a conversion function which is used
2558 | to convert the elements of the container with the same settings. The
2559 | third argument is a "cache" function which is needed to handle self
2560 | referential containers. Consider the following example. Suppose we have
2561 | a Javascript ``Pair`` class:
2562 |
2563 | .. code-block:: javascript
2564 |
2565 | class Pair {
2566 | constructor(first, second){
2567 | this.first = first;
2568 | this.second = second;
2569 | }
2570 | }
2571 |
2572 | We can use the following ``default_converter`` to convert ``Pair`` to ``list``:
2573 |
2574 | .. code-block:: python
2575 |
2576 | def default_converter(value, convert, cache):
2577 | if value.constructor.name != "Pair":
2578 | return value
2579 | result = []
2580 | cache(value, result);
2581 | result.append(convert(value.first))
2582 | result.append(convert(value.second))
2583 | return result
2584 |
2585 | Note that we have to cache the conversion of ``value`` before converting
2586 | ``value.first`` and ``value.second``. To see why, consider a self
2587 | referential pair:
2588 |
2589 | .. code-block:: javascript
2590 |
2591 | let p = new Pair(0, 0);
2592 | p.first = p;
2593 |
2594 | Without ``cache(value, result);``, converting ``p`` would lead to an
2595 | infinite recurse. With it, we can successfully convert ``p`` to a list
2596 | such that ``l[0] is l``.

2838 | desired result of the dict conversion. Some suggested values for
2839 | this argument:
2840 |
2841 | js.Map.new -- similar to the default behavior
2842 | js.Array.from -- convert to an array of entries
2843 | js.Object.fromEntries -- convert to a JavaScript object
2844 | default_converter: Callable[[Any, Callable[[Any], JsProxy], Callable[[Any, JsProxy], None]], JsProxy], default=None
2845 | If present will be invoked whenever Pyodide does not have some built in
2846 | conversion for the object. If ``default_converter`` raises an error, the
2847 | error will be allowed to propagate. Otherwise, the object returned will
2848 | be used as the conversion. ``default_converter`` takes three arguments.
2849 | The first argument is the value to be converted.
2850 |
2851 | Here are a couple examples of converter functions. In addition to the
2852 | normal conversions, convert ``Date`` to ``datetime``:
2853 |
2854 | .. code-block:: python
2855 |

2857 | from js import Date
2858 | def default_converter(value, _ignored1, _ignored2):
2859 | if isinstance(value, datetime):
2860 | return Date.new(value.timestamp() * 1000)
2861 | return value
2862 |
2863 | Don't create any PyProxies, require a complete conversion or raise an error:

2865 | .. code-block:: python
2866 |
2867 | def default_converter(_value, _ignored1, _ignored2):
2868 | raise Exception("Failed to completely convert object")
2869 |
2870 | The second and third arguments are only needed for converting
2871 | containers. The second argument is a conversion function which is used
2872 | to convert the elements of the container with the same settings. The
2873 | third argument is a "cache" function which is needed to handle self
2874 | referential containers. Consider the following example. Suppose we have
2875 | a Python ``Pair`` class:
2876 |
2877 | .. code-block:: python
2878 |
2879 | class Pair:
2880 | def __init__(self, first, second):
2881 | self.first = first
2882 | self.second = second
2883 |
2884 | We can use the following ``default_converter`` to convert ``Pair`` to ``Array``:
2885 |
2886 | .. code-block:: python
2887 |
2888 | from js import Array
2889 | def default_converter(value, convert, cache):
2890 | if not isinstance(value, Pair):
2891 | return value
2892 | result = Array.new()

2894 | result.push(convert(value.first))
2895 | result.push(convert(value.second))
2896 | return result
2897 |
2898 | Note that we have to cache the conversion of ``value`` before converting
2899 | ``value.first`` and ``value.second``. To see why, consider a self
2900 | referential pair:
2901 |
2902 | .. code-block:: javascript
2903 |
2904 | p = Pair(0, 0);
2905 | p.first = p;
2906 |
2907 | Without ``cache(value, result);``, converting ``p`` would lead to an
2908 | infinite recurse. With it, we can successfully convert ``p`` to an Array
