Run python code in typst using RustPython.
#import "@preview/pyrunner:0.2.0" as py
#let compiled = py.compile(
```python
def find_emails(string):
import re
return re.findall(r"\b[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}\b", string)
def sum_all(*array):
return sum(array)
```)
#let txt = "My email address is [email protected] and my friend's email address is [email protected]."
#py.call(compiled, "find_emails", txt)
#py.call(compiled, "sum_all", 1, 2, 3)Block mode is also available.
#let code = ```
f'{a+b=}'
```
#py.block(code, globals: (a: 1, b: 2))
#py.block(code, globals: (a: "1", b: "2"))The result will be a+b=3 and a+b='12'.
Due to restrictions of typst and its plugin system, some Python function will not work as expected:
- File and network IO will always raise an exception.
datatime.nowwill always return 1970-01-01.
Also, there is no way to import third-party modules. Only bundled stdlib modules are available. We might find a way to lift this restriction, so feel free to submit an issue if you want this functionality.
Run Python code block and get its result.
code: string | raw content - The Python code to run.globals: dict (named optional) - The global variables to bring into scope.
The last expression of the code block.
Compile Python code to bytecode.
code: string | raw content - The Python code to compile.
The bytecode representation in bytes.
Call a python function with arguments.
compiled: bytes - The bytecode representation of Python code.fn_name: string - The name of the function to be called...args: any - The arguments to pass to the function.
The result of the function call.
Install wasi-stub. You should use a slightly modified one. See the related issue.
