Trait ShellEnvironment 

pub trait ShellEnvironment: Send + Sync {
    // Required methods
    fn shell_exec(&self, script: &str) -> Result<()>;
    fn shell_exec_stdout(&self, script: &str) -> Result<String>;
    fn shell_exec_visible(&self, script: &str) -> Result<()>;
    fn log_info(&self, msg: &str);
    fn log_success(&self, msg: &str);

    // Provided methods
    fn log_warn(&self, _msg: &str) { ... }
    fn shell_exec_capture(&self, script: &str) -> Result<(String, String)> { ... }
}

Minimal shell execution abstraction used by dev-mode builds.

This trait provides just shell execution and logging — enough for dev_build() which runs nix build directly in the Lima VM.

Required Methods

fn shell_exec(&self, script: &str) -> Result<()>

Execute a shell script in the VM.

fn shell_exec_stdout(&self, script: &str) -> Result<String>

Execute a shell script in the VM and capture stdout.

fn shell_exec_visible(&self, script: &str) -> Result<()>

Execute a shell script with visible output.

fn log_info(&self, msg: &str)

Log an informational message.

fn log_success(&self, msg: &str)

Log a success message.

Provided Methods

fn log_warn(&self, _msg: &str)

Log a warning (optional; default no-op for test fakes).

fn shell_exec_capture(&self, script: &str) -> Result<(String, String)>

Execute a shell script, capturing both stdout and stderr.

Returns (stdout, stderr) on success. On failure, returns the exit code and captured stderr in the error. Used by the build pipeline to capture nix build errors for structured reporting.

Default: falls back to shell_exec_stdout (stderr not captured).
