coral-media/ext-ir
==================

[](#coral-mediaext-ir)

Information retrieval primitives for PHP.

Build requirements:

- System OpenBLAS is required.
- Linux/macOS: install OpenBLAS development package (for example `libopenblas-dev`).
- Windows: set `OPENBLAS_ROOT` to a prefix containing `include` and `lib\\openblas.lib`.
- Snowball is vendored under `lib/libstemmer` and built as part of the extension.

Install with PIE:

```
# from repository root
cd ext-ir
pie install -j"$(nproc)"
# from packagist
pie install coral-media/ext-ir
```

If OpenBLAS is installed in a non-default location:

```
cd ext-ir
OPENBLAS_PREFIX=/custom/prefix pie install -j"$(nproc)"
```

Build from source (manual):

```
cd ext-ir
phpize
./configure --with-php-config="$(command -v php-config)"
make -j"$(nproc)"
make test
sudo make install
```

Enable extension:

```
extension=ir
```

Windows notes:

- Ensure OpenBLAS is installed and `OPENBLAS_ROOT` points to the prefix.
- Build with the same PHP toolchain version/arch/thread-safety as target PHP.
- Prebuilt libraries availables under Releases section.

Current scaffold (`0.1.0`) includes:

- `ir_version()`
- `CoralMedia\IR\LinearAlgebra::{dot,normL2}()`
- `CoralMedia\IR\Text::{tokenize,stem}()`
- `CoralMedia\IR\Vectorizer::{frequency,vocabulary,fit,transform,fitTransform,tfIdf}()`
- `CoralMedia\IR\Similarity::{pearson,cosine,euclidean,nearest,topK}()`

Usage example:

```
