### Rust Edition
|
## MSRV
|
||||||
This project uses Rust **2018 edition** to ensure compatibility and stable language features.
|
The minimum supported Rust version is `1.60.0` for broader support.

|

|
||||||
|
|
||||||
|
### Set Current Directory
|
||||||
|
Specify the directory to run the command.
|
||||||
|
|
||||||
|
```rust
|
||||||
|
use comlexr::cmd;
|
||||||
|
|
||||||
|
let command = cmd!(
|
||||||
|
cd "~/";
|

|
);
|
||||||
|
|
||||||
|
assert_eq!(format!("{command:?}"), r#"cd "~/" && "echo" "test""#);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Setting Environment Variables
|
||||||
|
Set environment variables for the command.
|
||||||
|
|
||||||
|
```rust
|
||||||
|
use comlexr::cmd;
|
||||||
|
|
||||||
|
const NEW_VAR: &str = "NEW_VAR";
|
||||||
|
|
||||||
|
let command = cmd!(
|
||||||
|
env {
|
||||||
|
"TEST": "test",
|
||||||
|
NEW_VAR: "new_var"
|
||||||
|
};
|
||||||
|
"echo",
|
||||||
|
"test",
|
||||||
|
);
|
||||||
|
|
||||||
|
assert_eq!(format!("{command:?}"), r#"NEW_VAR="new_var" TEST="test" "echo" "test""#);
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Conditional
|
||||||
|
You can have a default value set for an environment variable.
|
||||||
|
|
||||||
|
```rust
|
||||||
|
use comlexr::cmd;
|
||||||
|
|
||||||
|
const NEW_VAR: &str = "NEW_VAR";
|
||||||
|
std::env::set_var("TEST", "realvalue");
|
||||||
|
|
||||||
|
let command = cmd!(
|
||||||
|
env {
|
||||||
|
"TEST":? "test",
|
||||||
|
NEW_VAR: "new_var"
|
||||||
|
};
|
||||||
|
"echo",
|
||||||
|
"test",
|
||||||
|
);
|
||||||
|
|
||||||
|
assert_eq!(format!("{command:?}"), r#"NEW_VAR="new_var" "echo" "test""#);
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Current Directory and Env Variable Order Matters
|
||||||
|
Environment variable declarations **MUST** come after the current directory declaration.
|
||||||
|
|
||||||
|
```rust
|
||||||
|
use comlexr::cmd;
|
||||||
|
|
||||||
|
let command = cmd!(
|
||||||
|
cd "~/";
|
||||||
|
env {
|
||||||
|
"TEST": "test",
|
||||||
|
};
|
||||||
|
"echo",
|
||||||
|
"test",
|
||||||
|
);
|
||||||
|
|
||||||
|
assert_eq!(
|
||||||
|
format!("{command:?}"),
|
||||||
|
r#"cd "~/" && TEST="test" "echo" "test""#
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Piping commands
|
||||||
|
When using the `pipe` feature, you can make use of `pipe!` to chain the stdout of commands to stdin. Execution is lazy so commands aren't run until `status()` or `output()` is called.
|
||||||
|
|
||||||
|
```rust
|
||||||
|
use comlexr::{pipe, cmd};
|
||||||
|
|
||||||
|
let dir = tempfile::tempdir().unwrap();
|
||||||
|
let file = dir.path().join("out");
|
||||||
|
let mut pipe = pipe!(cmd!("echo", "test") | cmd!("tee", &file));
|
||||||
|
|
||||||
|
let status = pipe.status().unwrap();
|
||||||
|
assert!(status.success());
|
||||||
|
```
|
||||||
|
|
||||||
|
### Sending variables to stdin
|
||||||
|
You can also send data to the stdin of the first command in the chain.
|
||||||
|
|
||||||
|
```rust
|
||||||
|
use comlexr::{pipe, cmd};
|
||||||
|
|
||||||
|
let mut pipe = pipe!(stdin = "test"; cmd!("sed", "s|e|oa|"));
|
||||||
|
let output = pipe.output().unwrap();
|
||||||
|
|
||||||
|
assert!(output.status.success());
|
||||||
|
assert_eq!(String::from_utf8_lossy(&output.stdout), "toast");
|
||||||
|
```
|
||||||
|

||||||
