Auto run command when some files changed.
fwatcher is implemented by rust language,
so you need cargo command:
cargo install fwatcher
fwatcher will be installed in your cargo binary directory(~/.cargo/bin/).
fwarcher can be use as a command:
``` $ fwatcher -h Usage: fwatcher [options] CMD
Options: -h, --help Display this message -v, --version Print version info -r, --restart Auto restart command -d, --directory
For example to search recursively for python files in the current directory and run pytest when a file is updated:
fwatcher -d . -p "**/*.py" "pytest"
you can also use more than one directory/pattern option:
fwatcher -d src -d test -p "**/*.py" -p "**/*.html" "pytest"
The --restart option kills the command if it's still running when a filesystem change happens. Can be used to restart locally running webservers on updates, or kill long running tests and restart on updates:
fwatcher -d src -p "**/*.py" --restart "run_forever_cmd"
Dependencies in your project's Cargo.toml:
toml
[dependencies]
glob = "0.2"
notify = "4.0"
fwatcher = "0.0.2"
The following example shows simple usage:
```rust extern crate glob; extern crate getopts; extern crate fwatcher;
use fwatcher::Fwatcher; use glob::Pattern; use std::path::PathBuf; use std::time::Duration;
fn main() { let dirs =vec![PatchBuf::new("src")]; let patterns = vec![Pattern::new("*/.py")]; let interval = Duration::new(i, 0); let restart = false; let cmd = vec!["pytest".to_string];
let mut fwatcher = Fwatcher::new(dirs, patterns, interval, restart, cmd);
fwatcher.run();
} ```
