Usage

Rust

use dkdc_sh::{which, require, run, run_with_env, tmux, git};

// Command checking
if which("tmux").is_some() { /* ... */ }
require("git")?;

// Run arbitrary commands
let output = run("echo", &["hello"])?;

// Run with custom environment variables
let output = run_with_env("cargo", &["build"], &[("RUSTFLAGS", "-D warnings")])?;

// Tmux session management
tmux::new_session("my-service", "python server.py")?;
tmux::send_keys("my-service", "reload")?;
let logs = tmux::capture_pane("my-service", Some(50))?;
tmux::kill_session("my-service")?;

// Git operations
git::clone_shallow("https://github.com/org/repo.git", &dest, "main")?;
git::clone_shallow_with_env(
    "https://github.com/org/repo.git", &dest, "main",
    &[("GIT_SSH_COMMAND", "ssh -i ~/.ssh/deploy_key")],
)?;
git::checkout_new_branch(&repo_dir, "feature/branch")?;
git::config_set(&repo_dir, "user.email", "bot@example.com")?;
let log = git::cmd_with_env(&repo_dir, &["log", "--oneline"], &[("GIT_PAGER", "cat")])?;

Python

import dkdc_sh

# Command checking
path = dkdc_sh.which("tmux")
dkdc_sh.require("git")

# Run commands
output = dkdc_sh.run("echo", ["hello"])

# Run with custom environment variables
output = dkdc_sh.run("cargo", ["build"], env=[("RUSTFLAGS", "-D warnings")])

# Tmux
dkdc_sh.tmux_new_session("my-service", "python server.py")
dkdc_sh.tmux_send_keys("my-service", "reload")
logs = dkdc_sh.tmux_capture_pane("my-service", lines=50)
dkdc_sh.tmux_kill_session("my-service")

# Git
dkdc_sh.git_clone_shallow("https://github.com/org/repo.git", "./dest", "main")
dkdc_sh.git_checkout_new_branch("./repo", "feature/branch")
output = dkdc_sh.git_cmd("./repo", ["log", "--oneline"])

Error handling

Rust

The library uses a unified Error enum:

Python

All errors are raised as RuntimeError.
