# Import Expression Parser (for lack of a better name)
|
||
|
||

|

[](https://coveralls.io/github/iomintz/import-expression-parser?branch=main)
|
||
|
||
Import Expression Parser converts code like this:
|
||
|
||
```py
|
||
urllib.parse!.quote('hello there')
|
||
```
|
||
|
||
Into this equivalent code:
|
||
```py
|
||
importlib.import_module('urllib.parse').quote('hello there')
|
||
```
|
||
|
||
## Usage
|
||
|
||
```py
|
||
>>> import import_expression
|
||
>>> import_expression.eval('collections!.Counter("bccdddeeee")')
|
||
Counter({'e': 4, 'd': 3, 'c': 2, 'b': 1})
|
||
```
|
||
|
||
The other public functions are `exec`, `compile`, and `parse`. See their docstrings for details.
|
||
|
||
By default, the filename for `SyntaxError`s is `<string>`.
|
||
To change this, pass in a filename via the `filename` kwarg.
|
||
|
||
### AST usage
|
||
|
||
<!-- TODO document usage like jishaku or how one could build a REPL -->
|
||
|
||
### REPL usage
|
||
|
||
Run `import_expression` for an import expression enabled REPL. \
|
||
Run `import_expression -a` for a REPL that supports both import expressions and top level `await` (3.8+).
|
||
|
||
See `import_expression --help` for more details.
|
||
|
||
### Monkey Patching the REPL
|
||
|
||
`import_expression.patch.patch` is deprecated in favor of using `python -m import_expression`.
|
||
|
||
## Limitations / Known Issues
|
||
|
||
* Due to the hell that is f-string parsing, and because `!` is already an operator inside f-strings,
|
||
import expressions inside f-strings will likely never be supported.
|
||
* Due to python limitations, results of `import_expression.exec` will have no effect on the caller's globals or locals
|
||
without an explicit `globals` argument.
|
||
* Unlike real operators, spaces before and after the import expression operator (such as `x ! .y` are not supported).
