## Installation

```bash

pip install VerbalExpressions

```

## Usage

```python

from verbalexpressions import VerEx

verbal_expression = VerEx()

```

## Examples

### Testing if we have a valid URL

```python

# Create an example of how to test for correctly formed URLs

verbal_expression = VerEx()

tester = (verbal_expression.

            start_of_line().

            find('http').

            maybe('s').

            find('://').

            maybe('www.').

            anything_but(' ').

            end_of_line()

)

# Create an example URL

test_url = "https://www.google.com"

# Test if the URL is valid

if tester.match(test_url):

    print "Valid URL"

# Print the generated regex

print tester.source() # => ^(http)(s)?(\:\/\/)(www\.)?([^\ ]*)$

```

### Replacing strings

```python

# Create a test string

replace_me = "Replace bird with a duck"

# Create an expression that looks for the word "bird"

expression = VerEx().find('bird')

# Execute the expression in VerEx

result_VerEx = expression.replace(replace_me, 'duck')

print result_VerEx

# Or we can compile and use the regular expression using re

import re

regexp = expression.compile()

result_re = regexp.sub('duck', replace_me)

print result_re

```

### Shorthand for string replace

```python

result = VerEx().find('red').replace('We have a red house', 'blue')

print result

```

## Developer setup : running the tests

```bash

python setup.py develop

python setup.py test

```
