Debian Changelog parser
=======================
This crate provides a parser for debian/changelog files, as described in the
Debian policy,
[section 4.4](https://www.debian.org/doc/debian-policy/ch-source.html#debian-changelog-debian-changelog).
The parser builds a CST. It is lossless - i.e. preserves formatting, and allows
editing and partial parsing.
Example:
```rust
use std::io::Read;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let file = std::fs::File::open("/usr/share/doc/rustc/changelog.Debian.gz")?;
let mut gz = flate2::read::GzDecoder::new(file);
let mut contents = String::new();
gz.read_to_string(&mut contents)?;
let changelog: debian_changelog::ChangeLog = contents.parse()?;
for entry in changelog.entries() {
println!(
"{}: {}",
entry.package().unwrap(),
entry.version().unwrap().to_string()
);
}
Ok(())
}
```
Or to update an existing changelog file:
```rust
use std::io::Read;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let file = std::fs::File::open("debian/changelog")?;
let mut contents = String::new();
file.read_to_string(&mut contents)?;
let mut changelog: debian_changelog::ChangeLog = contents.parse()?;
changelog.try_auto_add_change(
&["* Make a change"],
(
"Jelmer Vernooij".to_string(),
"jelmer@debian.org".to_string(),
),
None,
None,
)?;
std::fs::write("debian/changelog", changelog.to_string())?;
Ok(())
}
```
