# Geddes
[](https://crates.io/crates/geddes)
[](https://pypi.org/project/geddes/)

A Rust XRD pattern parser with Python and Node.js bindings. Supports:
- `.raw` (GSAS text or Bruker binary)
- `.rasx` (Rigaku Zip archive)
- `.xrdml` (Panalytical XML)
- `.xy` / `.xye` (Space-separated ASCII)
- `.csv` (Comma-separated values)
## Rust Usage
Load from a file path:
```rust
use geddes::read;
fn main() {
let pattern = read("tests/data/xy/sample.xy").unwrap();
println!("{} {}", pattern.x.len(), pattern.y.len());
}
```
Load from in-memory bytes (filename is used to infer the format):
```rust
use std::fs;
use geddes::read_bytes;
fn main() {
let data = fs::read("tests/data/xy/sample.xy").unwrap();
let pattern = read_bytes(&data, "sample.xy").unwrap();
println!("{} {}", pattern.x.len(), pattern.y.len());
}
```
## Python Usage
Load from a file path:
```python
import geddes
pattern = geddes.read("tests/data/xy/sample.xy")
print(len(pattern.x), len(pattern.y))
```
Load from in-memory bytes (filename is used to infer the format):
```python
import geddes
with open("tests/data/xy/sample.xy", "rb") as f:
data = f.read()
pattern = geddes.read_bytes(data, "sample.xy")
print(len(pattern.x), len(pattern.y))
```
## Node.js Usage
Load from a file path:
```javascript
const geddes = require('@jcwang587/geddes')
const pattern = geddes.read('tests/data/xy/sample.xy')
console.log(pattern.x.length, pattern.y.length)
```
Load from in-memory bytes (filename is used to infer the format):
```javascript
const fs = require('node:fs')
const geddes = require('@jcwang587/geddes')
const bytes = fs.readFileSync('tests/data/xy/sample.xy')
const pattern = geddes.readBytes(bytes, 'sample.xy')
console.log(pattern.x.length, pattern.y.length)
```
