**Capabilities:**
* This package is a work-in-progress and is largely untested -- it works for
2020-04-17 13:51:43 -07:00
the tasks I usually use it for, but I can't guarantee I've even
2017-09-18 03:01:48 -07:00
tried the features you happen to use! Use at your own risk!
* Interfaces and datastructures are subject to change!
* That said the following work for me:
- polygons
- layer info
- cell names
- compressed blocks
- basic property I/O

## Documentation
Most functions and classes are documented inline.
2017-09-18 03:01:48 -07:00
2017-09-18 03:08:18 -07:00
To read the inline help,
```python3
import fatamorgana
help(fatamorgana.OasisLayout)
```
The documentation is currently very sparse and I expect to improve it whenever possible!
## Examples

Read an OASIS file and write it back out:
```python3
import fatamorgana
with open('test.oas', 'rb') as f:
layout = fatamorgana.OasisLayout.read(f)
2020-04-17 13:51:43 -07:00
2017-09-18 03:08:18 -07:00
with open('test_write.oas', 'wb') as f:
layout.write(f)
```
