## Quick start
|
||
|
|
|
||
|
|
```rust

||
|
|
use watchexec::{
|
||
|
|
config::ConfigBuilder,
|
||
|
|
error::Result,
|
||
|
|
pathop::PathOp,
|
||
|
|
run::{
|
||
|
|
ExecHandler,
|
||
|
|
Handler,
|
||
|
|
watch,
|
||
|
|
},
|
||
|
|
};
|
||
|
|
|
||
|
|
fn main() -> Result<()> {
|
||
|
|
let config = ConfigBuilder::default()
|
||
|
|
.clear_screen(true)
|
||
|
|
.run_initially(true)
|
||
|
|
.paths(vec![ "/path/to/dir".into() ])
|
||
|
|
.cmd(vec![ "date; seq 1 10".into() ])
|
||
|
|
.build()?;
|
||
|
|
|
||
|
|
let handler = MyHandler(ExecHandler::new(options)?);
|
||
|
|
watch(&handler)
|
||
|
|
}
|
||
|
|
|
||
|
|
struct MyHandler(ExecHandler);
|
||
|
|
|

|
|
|
||
|
|
fn on_manual(&self) -> Result<bool> {
|
||
|
|
println!("Running manually!");
|
||
|
|
self.0.on_manual()
|
||
|
|
}
|
||
|
|
|
