## What is actrie?
In the beginning, **actrie** is an implementation of Aho-Corasick automation, optimize for large scale multi-pattern.
Now, we support more types of pattern: anti-ambiguity pattern, anti-antonym pattern, distance pattern, alternation pattern, etc. You can combine all of them together.
## Pattern syntax
### 1. **plain** pattern
> **abc**
### 2. **anti-ambiguity** pattern
> center **(?&!** ambiguity **)**
### 3. **anti-antonym** pattern
> **(? prefix **.{min,max}** suffix
### 5. **alternation** pattern
> pattern0 **|** pattern1
### 6. **wrapper** pattern
> **(** pattern **)**
## Build and install
### 1. Build C library
```bash
# download source
git clone --depth=1 --recurse-submodules --shallow-submodules https://github.com/ifplusor/actrie.git
# go to project directory
cd actrie
# make build directory
mkdir build && pushd build
# configure cmake project
cmake -DCMAKE_BUILD_TYPE=Release ..
# configure cmake project if no stdatomic.h in gcc
#cmake -DCMAKE_BUILD_TYPE=Release -D__GCC_ATOMICS__=ON ..
# build alib and actrie libraries
make actrie
popd
```
### 2. Build and install Python package
```bash
# build wheel package
python setup.py bdist_wheel
# install wheel package
pip install dist/actrie-*.whl
# Or install from PyPI
pip install actrie
```
### 3. Build and install Java package
```bash
# go to jni directory
pushd jni
# build nar package
mvn clean package
# install to local maven repository
mvn install
popd
```
## Example
### vocab.txt
```text
f|(a|b).{0,5}(e(?&!ef)|g) pattern0
abc pattern1
efg pattern2
```
### **Python**: example.py
```python
#!/usr/bin/env python
# coding=utf-8
from actrie import *
# with open("vocab.txt") as rf:
# pattern = rf.read()
pattern = """
f|(a|b).{0,5}(e(?&!ef)|g)
abc
efg
"""
content = "abcdefg"
def test():
global pattern, content
# create matcher by file
# matcher = Matcher.create_by_file("vocab.txt")
# create matcher by string
matcher = Matcher.create_by_string(pattern)
# iterator
for matched in matcher.finditer(content):
print(matched)
# find all
all_matched = matcher.findall(content)
print(all_matched)
if __name__ == "__main__":
test()
```
### **Java**: Example.java
```java
package psn.ifplusor.actrie;
public class Example {
public static void main(String[] args) {
String pattern = "f|(a|b).{0,5}(e(?&!ef)|g)\nabc\nefg";
String content = "abcdefg";
// create matcher by string
try (Matcher matcher = Matcher.createByString(pattern)) {
try (Context context = matcher.match(content)) {
// iterator
for (Word word : context) {
System.out.println(word);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
