Installation

You can install the latest release version from PyPI:

pip install pyrematch

Or you can build from the source code:

git clone [e-mail]:REmatchChile/REmatch.git
cd REmatch
pip install .

Usage

Here is an example that prints all the matches using the finditer function.

import pyrematch as REmatch

# Define the document and the REQL pattern
document = "[e-mail]\[e-mail]\[e-mail]"
pattern = r"@!domain{(\w+\.)+\w+}(\n|$)"

# Create a REQL query
query = REmatch.reql(pattern)

# Execute the query and print the results
for match in query.finditer(document):
    print(match)

The Query object contains also other useful methods. To get a single match, you can use:

query.findone(document)

To find all the matches, you can use:

query.findall(document)

To find a limited number of matches, you can use:

limit = 10
query.findmany(document, limit)

To check if a match exists, you can use:

query.check(document)
