# Description
Implements a Pharo uFFI wrapper to the Martin Porter’s [Stemming algorithm](https://en.wikipedia.org/wiki/Stemming). This algorithm remove and replace well-known suffixes of English words. Basically it provides a single method #stem: which receive an English String to stem, and answer its stemmed version.
# Installation
```smalltalk
EpMonitor disableDuring: [
Metacello new
baseline: 'LibStemmer';
repository: 'github://hernanmd/libstemmer/src';
load ].
```
The library should detect automatically for your platform. If it is not the case, please open an [issue](https://github.com/hernanmd/libstemmer/issues).
# How to compile the library
Instead of using the library provided in this repository, you can compile your own version in your box. In that case first make sure you have clang installed and clone the following repository:
```bash
git clone https://github.com/wooorm/stmr.c
cd stmr.c
```
Then edit the stmr.c file to add `extern` in the `stem()` function prototype.
## macOS
```bash
clang -shared -undefined dynamic_lookup -o libstmr.dylib stmr.c
```
## Windows
```bash
clang -shared -o libstmr.dll stmr.c
```
## Linux
TBD
## Baseline String
If you want to add the LibStemmer to your Metacello Baselines or Configurations, copy and paste the following expression:
```smalltalk
" ... "
spec
baseline: 'LibStemmer'
with: [ spec repository: 'github://hernanmd/libstemmer/src' ];
" ... "
```
# Usage
```smalltalk
| englishStemmer |
englishStemmer := FFILibStemmer uniqueInstance.
englishStemmer stem: 'considerations'. "'consider'"
englishStemmer stem: 'eating'
```

## Version management
This project use semantic versioning to define the releases. This means that each stable release of the project will be assigned a version number of the form `vX.Y.Z`.
- **X** defines the major version number
- **Y** defines the minor version number
- **Z** defines the patch version number
When a release contains only bug fixes, the patch number increases. When the release contains new features that are backward compatible, the minor version increases. When the release contains breaking changes, the major version increases.
Thus, it should be safe to depend on a fixed major version and moving minor version of this project.
