Name: python-import-expression

# Import Expression Parser (for lack of a better name)
[](https://travis-ci.org/iomintz/import-expression-parser)
[](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`, `parse`, `find_imports`, and `update_globals`.
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.
### Reusing compiled code objects
import_expression.eval/exec/compile should not be passed strings in a tight loop. \
Doing so will recompile the string every time. Instead, you should pre-compile the string to a code object
and pass that to import_expression.eval / import_expression.exec.
For example, instead of this:
```py
for line in sys.stdin:
print(import_expression.eval('foo!.bar(l)', dict(l=line))
```
Prefer this:
```py
code = import_expression.compile('foo!.bar(l)', mode='eval')
for line in sys.stdin:
print(import_expression.eval(code, dict(l=line)))
```
### Custom encoding
```py
# encoding: import_expression
print(typing!.TYPE_CHECKING)
```
This file, when run, will print True/False. For maximum laziness you can also do `#coding:ie`.
### 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.
### Running a file
Run `import-expression <filename.py>`.
### File rewriter
Run `import-expression-rewrite <file.py>` to rewrite a file containing import expressions to standard Python. \
Add the `-i` flag to rewrite in-place.
## 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.
