# Python-Skill Bridge
[](https://badge.fury.io/py/skillbridge)
### Prerequisites
- Python 3.8 or higher[^1]
- pip
- IC 6.1.7 or ICADV/M or higher
[^1]: For Python 3.6 and Python 3.7 please install version `1.5.1` (`pip install skillbridge==1.5.1`)
### Features
- Run Virtuoso's Skill functions from Python
- Automatically translate all Skill objects to Python
- Automatically translate Python numbers, booleans, strings, lists and dictionaries to Skill
- Retrieve Skill function documentation in Python
- Convenient tab-completion (+ jupyter support)
- object attributes
- global function list
- methods
Read more in the [full documentation](https://unihd-cag.github.io/skillbridge/).
### Installation
```bash
pip install skillbridge
```
Add the `--user` option if you don't want to install it systemwide.
Before you can use the Skill bridge you must generate the function definitions from
Virtuoso via the Skill console.
1. Type `skillbridge path` into your shell to acquire the correct `PATH-TO-IPC-SERVER`
2. Open Virtuoso
2. Type these commands into the Skill console
- `load("PATH-TO-IPC-SERVER")`
After that you can also generate the static completion stub files. This is useful for code completion
in certain IDEs (e.g. PyCharm)
- Type `skillbridge generate` into your shell.
### Updating
In order to update the python package type this
```bash
pip install skillbridge --upgrade
```
### Examples
**_Note:_** All these examples assume that the Skill server is running. You can
start it by typing the following command into the Skill console.
```lisp
load("PATH-TO-IPC-SERVER")
pyStartServer
```
##### Connecting to the server
```python
from skillbridge import Workspace
ws = Workspace.open()
```
##### Accessing the currently open edit cell view
```python
cell_view = ws.ge.get_edit_cell_view()
```
##### Inspecting available properties
```python
>>> dir(cell_view)
['DBUPerUU', 'any_inst_count', 'area_boundaries', 'assoc_text_displays', 'b_box', ...]
```
or type `cell_view.` in jupyter/ipython
##### Reading properties
```python
>>> print(cell_view.b_box)
[[0, 10], [2, 8]]
```
##### Call any SKILL function
```python
>>> ws['plus'](3, 4)
7
```
*equivalent to:*
```lisp
(plus 3 4)
```
