# AIA Tools
AIA Tools is a Python library for interacting with App Inventor Application (AIA) files in Python. It is useful for opening, summarizing, and analyzing AIA files for research inquiries. The query API is inspired by SQLalchemy
## Installing
```shell
$ pip install aiatools
```
For development:
```shell
$ pyenv install 3.6.3
$ pyenv virtualenv 3.6.3 aiatools
$ pyenv activate aiatools
$ pip install -r requirements.txt
$ pip install .
```
## Usage Examples
```python
from aiatools import AIAFile
with AIAFile('MyProject.aia') as aia:
print('Number of screens: %d\n' % len(aia.screens))
print('Number of components: %d\n' % len(aia.screens['Screen1'].componentiter()))
print('Number of blocks: %d\n' % len(aia.screens['Screen1'].blockiter()))
print('Number of event blocks: %d\n' % len(aia.screens['Screen1'].blockiter(type='component_event')))
aia.screens['Screen1'].blocks(type=='component_event').count(by='event_name')
```
```python
from aiatools import AIAFile
from aiatools.attributes import event_name, type
from aiatools.block_types import *
from aiatools.component_types import *
aia = AIAFile('MyProject.aia')
# Count the number of screens
print len(aia.screens)
# Count the number of distinct component types used on Screen1
print aia.screens['Screen1'].components().count(group_by=type)
# Count the number of Button components on Screen1
print aia.screens['Screen1'].components(type==Button).count()
# Count the number of component_event blocks, grouped by event name
print aia.screens['Screen1'].blocks(type==component_event).count(group_by=event_name)
# Compute the average depth of the blocks tree in Button.Click handlers
print aia.screens['Screen1'].blocks(type==component_event && event_name == Button.Click).avg(depth)
# Count the number of blocks referencing a specific component
print aia.screens['Screen1'].components(name=='Button1').blocks().count()
# Count the number of event handlers where the event opens another screen
print aia.blocks(type==component_event).descendants(type==control_openAnotherScreen).count()
# Get the screens where the user has included more than one TinyDB
print aia.screens().components(type==TinyDB).count(group_by = Screen.name).filter(lambda k,v: v > 1)
```
## Selectors
```python
project = AIAFile('project.aia')
project.screens() # Select all screens
project.screens('Screen1') # Select Screen1
project.screens(Button.any) # Select any screen with at least 1 button
project.screens(Control.open_another_screen) # Select any screen containing an open_another_screen block
project.screens(Component.Name == 'TinyDb1') # Select any screen containing a component named TinyDb1
```

## Attributes
`depth` - For a component, this is the depth of the component hierarchy rooted at that component. For components that are not containers this value is always 1. For containers and blocks, this is the longest length of the paths from this root node to any of its leaf nodes.
`length` - The number of direct descendants of the target. If the target is a component container, it will be the number of direct chidlren. For a block, it will be the number of
`children` - The list of children for the item(s) in the set. If more than one item is in the set, the children will be provided in the order of their parents.
`mutators` - If the block has mutations, a list of strings indicating the types of the mutations, e.g. ['if', 'elseif', 'elseif', 'else'].
`callers` - For procedures, the number of caller blocks in the workspace. For variables and component methods and properties, the number of getter blocks.
## Aggregation
`max` - Maximum value of the filter
`min` - Minimum value of the filter
`avg` - Average value of the filter
`count` - Count of items matching the filter
`median` - Median value of the attribute
