+# Changelog
+
+## 2026-05-09 - 3.4.0 - feat(smartshell)
+add cwd-aware execution options, structured strict-mode errors, and safer process tree termination
+
+- adds cwd and env runtime options across exec, spawn, interactive, wait-for-line, and PTY execution APIs
+- introduces SmartshellError with exit code, signal, stdout, stderr, and combined result details for strict-mode failures
+- terminates timed-out commands via process tree killing to prevent detached child processes from continuing after timeout
+
+## 2026-03-15 - 3.3.8 - fix(repo)
+remove obsolete Serena project configuration files
+
+- Deletes the .serena project configuration from the repository
+- Cleans up editor or tooling metadata that is not part of the package runtime or source code
+
+## 2026-03-05 - 3.3.7 - fix(smartshell)
+avoid triple shell nesting, improve WSL path filtering, and use chunked log buffer to reduce memory usage
+
+- Spawn uses the executor shell binary directly (e.g. /bin/bash) and removes extra bash -c wrapping to avoid triple shell nesting
+- Only filter out /mnt/c/ and other WSL-specific PATH entries when running under WSL (adds _isWSL detection)
+- Replace single concatenated Buffer with chunked buffering in ShellLog (lazy concatenation, logLength property) and update checks to use logLength
+- Remove unused dependency "tree-kill" from package.json
+
+## 2026-03-04 - 3.3.6 - fix(smartshell)
+use 'close' event on child processes to ensure exit handling and update dependency versions
+
+- Replace child_process 'exit' listeners with 'close' in ts/classes.smartshell.ts (two occurrences) to ensure handlers run after stdio streams are closed.
+- Bump devDependencies: @git.zone/tsbuild ^2.7.3 -> ^4.1.2, @git.zone/tsrun ^1.6.2 -> ^2.0.1, @git.zone/tstest ^2.8.3 -> ^3.2.0, @types/node ^22.19.13 -> ^25.3.3.
+- Bump dependencies: @push.rocks/smartexit ^2.0.1 -> ^2.0.3, which ^5.0.0 -> ^6.0.1.
+
+## 2026-03-03 - 3.3.2 - fix(release)
+add @git.zone/cli release configuration with registries and public access
+
+- Updated file: npmextra.json
+- Added @git.zone/cli.release.registries: https://verdaccio.lossleess.digital, https://registry.npmjs.org
+- Set @git.zone/cli.release.accessLevel to "public"
+
+## 2026-03-03 - 3.3.1 - fix(deps)
+bump @push.rocks/smartexit dependency to ^1.1.1
+
+- Updated @push.rocks/smartexit from ^1.0.23 to ^1.1.1
+- Only package.json was modified
+- Project current version is 3.3.0; recommend a patch release to 3.3.1
+
+## 2025-08-17 - 3.3.0 - feat(smartshell)
+Add secure spawn APIs, PTY support, interactive/streaming control, timeouts and buffer limits; update README and tests
+
+- Introduce execSpawn family (execSpawn, execSpawnStreaming, execSpawnInteractiveControl) for shell-free, secure execution of untrusted input (shell:false).
+- Add PTY support (optional node-pty) with execInteractiveControlPty and execStreamingInteractiveControlPty; PTY is lazy-loaded and documented as an optional dependency.
+- Expose interactive control primitives (sendInput, sendLine, endInput, finalPromise) for both spawn and shell-based executions, and streaming interfaces with process control (terminate, kill, keyboardInterrupt, customSignal).
+- Implement timeouts, maxBuffer limits and onData callbacks to prevent OOM, stream output incrementally, and support early termination and debugging logs.
+- Improve process lifecycle handling: safe unpipe/unpipe-on-error, smartexit integration, and safer signal-based tree-kill behavior.
+- Enhance execAndWaitForLine with timeout and terminateOnMatch options to allow pattern-based waits with configurable behavior.
+- Update README with a Security Guide recommending execSpawn for untrusted input, PTY usage guidance, and new feature documentation (timeouts, buffer limits, debug mode, environment control).
+- Add extensive tests covering error handling, interactive control, passthrough, PTY behavior, spawn behavior, silent/streaming modes and environment propagation.
+
+## 2025-08-16 - 3.2.4 - fix(tests)
+Update tests & CI config, bump deps, add docs and project configs
+
+- Add comprehensive README overhaul with detailed usage, examples, API reference and best practices.
+- Add extensive silent-mode tests (test/test.silent.ts) to validate execSilent, execStrictSilent, execStreamingSilent and execAndWaitForLineSilent behaviors.
+- Update test runner and script: test script now runs tstest with --verbose, --logfile and --timeout; tests now import tapbundle from @git.zone/tstest.
+- Fix import in test/test.ts to use @git.zone/tstest/tapbundle.
+- Bump devDependencies: @git.zone/tsbuild -> ^2.6.4, @git.zone/tstest -> ^2.3.2; bump @push.rocks/smartpromise -> ^4.2.3.
+- Add typings entry and packageManager field to package.json.
+- Add project configuration files (.serena/project.yml) and local settings (.claude/settings.local.json).

+# @push.rocks/smartshell
+
+`@push.rocks/smartshell` is a TypeScript-first Node.js library for running shell commands with modern async APIs. It wraps `child_process` in promises, adds strict and silent execution modes, supports streaming and programmatic stdin control, exposes safer shell-free spawn methods for untrusted arguments, and gives you practical process controls like timeouts, process-tree termination, custom environments, working directories, and optional PTY-backed terminal emulation.
+
+## Issue Reporting and Security
+
+For reporting bugs, issues, or security vulnerabilities, please visit [community.foss.global/](https://community.foss.global/). This is the central community hub for all issue reporting. Developers who sign and comply with our contribution agreement and go through identification can also get a [code.foss.global/](https://code.foss.global/) account to submit Pull Requests directly.
+
+## Install
+
+```bash
+pnpm add @push.rocks/smartshell
+```
+
+PTY support is optional and only needed when a command requires a real terminal:
+
+```bash
+pnpm add --save-optional node-pty
+```
+
+## Quick Start
+
+```typescript
+import { Smartshell } from '@push.rocks/smartshell';
+
+const shell = new Smartshell({
+  executor: 'bash',
+});
+
+const result = await shell.exec('echo "hello from smartshell"');
+
+console.log(result.exitCode); // 0
+console.log(result.stdout); // hello from smartshell
+```
+
+Use `execSpawn()` whenever command arguments include user input or any other untrusted value:
+
+```typescript
+const filenameFromUser = 'report.txt; rm -rf /';
+
+// Safe: no shell is used, so metacharacters are treated as argument text.
+const result = await shell.execSpawn('cat', [filenameFromUser], {
+  silent: true,
+});
+```
+
+## What It Does
+
+- Promise-based command execution for `async`/`await` code.
+- Shell-based methods for trusted command strings.
+- Shell-free spawn methods for safer argument handling.
+- Silent, strict, streaming, passthrough, and interactive-control modes.
+- Process-tree cleanup through `@push.rocks/smartexit`.
+- Timeout support for terminating long-running process trees.
+- `cwd`, `env`, and `AbortSignal` support.
+- Bounded output buffering with `maxBuffer`.
+- Separate `stderr` capture plus the historical combined output buffer.
+- Optional PTY support through `node-pty` for terminal-native programs.
+- A small `SmartExecution` helper for restarting long-running commands.
+- The `which` utility re-exported for command discovery.
+
+## Execution Modes
+
+### Standard Execution
+
+`exec()` runs a trusted command string through the configured shell and resolves with an `IExecResult`.
+
+```typescript
+const result = await shell.exec('git --version');
+
+console.log(result.exitCode);
+console.log(result.stdout);
+```
+
+Shell execution is convenient for hardcoded command strings, pipes, redirects, globbing, and shell syntax:
+
+```typescript
+await shell.exec('mkdir -p dist && cp assets/*.json dist/');
+```
+
+### Silent Execution
+
+`execSilent()` captures output without writing it to the current process stdout.
+
+```typescript
+const result = await shell.execSilent('node --version');
+console.log(result.stdout.trim());
+```
+
+### Strict Execution
+
+`execStrict()` rejects with `SmartshellError` when the command exits with a non-zero code or is terminated by a signal.
+
+```typescript
+import { SmartshellError } from '@push.rocks/smartshell';
+
+try {
+  await shell.execStrict('pnpm test');
+} catch (error) {
+  if (error instanceof SmartshellError) {
+    console.error(error.message);
+    console.error(error.exitCode);
+    console.error(error.stderr);
+  }
+}
+```
+
+Use `execStrictSilent()` for strict behavior without console output:
+
+```typescript
+await shell.execStrictSilent('pnpm build');
+```
+
+### Streaming Execution
+
+`execStreaming()` starts a command and returns immediately with the child process, a final result promise, and process-control helpers.
+
+```typescript
+const streaming = await shell.execStreaming('pnpm install');
+
+streaming.childProcess.stdout?.on('data', (chunk) => {
+  process.stdout.write(`[install] ${chunk}`);
+});
+
+const result = await streaming.finalPromise;
+console.log(result.exitCode);
+```
+
+Streaming executions can be controlled explicitly:
+
+```typescript
+const server = await shell.execStreaming('pnpm dev', false, {
+  cwd: '/path/to/app',
+});
+
+await server.keyboardInterrupt(); // SIGINT
+await server.terminate(); // SIGTERM
+await server.kill(); // SIGKILL
+await server.customSignal('SIGHUP');
+```
+
+`execStreamingSilent()` starts a streaming command without printing output automatically.
+
+### Passthrough Execution
+
+`execPassthrough()` pipes the current process stdin into the command. This is useful for commands that should receive real user input while still returning a result.
+
+```typescript
+await shell.execPassthrough('read name && echo "hello $name"');
+```
+
+`execStreamingPassthrough()` combines passthrough stdin with the streaming interface.
+
+### Programmatic Input Control
+
+`execInteractiveControl()` returns methods for sending stdin manually.
+
+```typescript
+const interactive = await shell.execInteractiveControl('cat');
+
+await interactive.sendLine('first line');
+await interactive.sendInput('second line without newline');
+await interactive.sendInput('\n');
+interactive.endInput();
+
+const result = await interactive.finalPromise;
+console.log(result.stdout);
+```
+
+`execStreamingInteractiveControl()` gives you both programmatic input and streaming process controls:
+
+```typescript
+const repl = await shell.execStreamingInteractiveControl('node');
+
+await repl.sendLine('console.log(21 * 2)');
+await repl.sendLine('.exit');
+
+await repl.finalPromise;
+```
+
+### Interactive Shell Execution
+
+`execInteractive()` runs a trusted shell command with inherited stdio. It is meant for fully interactive terminal use and returns `void`; in CI environments it intentionally does nothing.
+
+```typescript
+await shell.execInteractive('vim readme.md');
+```
+
+## Secure Spawn APIs
+
+The `execSpawn()` family uses `child_process.spawn()` with `shell: false`. That means shell metacharacters are not interpreted.
+
+```typescript
+const result = await shell.execSpawn('git', ['status', '--short'], {
+  cwd: '/path/to/repo',
+  silent: true,
+});
+```
+
+### Why Spawn Matters
+
+```typescript
+const userInput = 'file.txt; rm -rf /';
+
+// Dangerous: shell syntax in userInput can be interpreted.
+await shell.exec(`cat ${userInput}`);
+
+// Safe: userInput is passed as one literal argument.
+await shell.execSpawn('cat', [userInput]);
+```
+
+### Spawn Streaming
+
+```typescript
+const streaming = await shell.execSpawnStreaming('pnpm', ['test'], {
+  cwd: '/path/to/package',
+});
+
+const result = await streaming.finalPromise;
+```
+
+### Spawn Interactive Control
+
+```typescript
+const interactive = await shell.execSpawnInteractiveControl('cat', []);
+
+await interactive.sendLine('hello');
+interactive.endInput();
+
+const result = await interactive.finalPromise;
+```
+
+PTY mode is currently available for shell-based interactive-control methods, not for `execSpawn()`.
+
+## PTY Support
+
+Some tools behave differently when they are connected to pipes instead of a real terminal. Editors, REPLs, password prompts, full-screen terminal UIs, readline prompts, and programs that depend on ANSI terminal behavior often need a PTY.
+
+Install the optional dependency first:
+
+```bash
+pnpm add --save-optional node-pty
+```
+
+Then use the PTY-specific methods:
+
+```typescript
+const prompt = await shell.execInteractiveControlPty(
+  'bash -c \'read -p "Name: " name && echo "Hello $name"\''
+);
+
+await prompt.sendLine('Ada');
+
+const result = await prompt.finalPromise;
+console.log(result.stdout);
+```
+
+Streaming PTY control works the same way, with PTY-backed process controls:
+
+```typescript
+const nodeRepl = await shell.execStreamingInteractiveControlPty('node');
+
+await nodeRepl.sendLine('console.log("PTY ready")');
+await nodeRepl.sendLine('.exit');
+
+await nodeRepl.finalPromise;
+```
+
+PTY output combines stdout and stderr because terminal sessions expose a single terminal data stream.
+
+## Runtime Options
+
+Most execution methods accept these options:
+
+```typescript
+interface TExecCommandOptions {
+  ptyCols?: number;
+  ptyRows?: number;
+  ptyTerm?: string;
+  ptyShell?: string;
+  maxBuffer?: number;
+  onData?: (chunk: Buffer | string) => void;
+  timeout?: number;
+  debug?: boolean;
+  env?: NodeJS.ProcessEnv;
+  cwd?: string;
+  signal?: AbortSignal;
+}
+```
+
+### Working Directory
+
+Prefer the `cwd` option over embedding `cd ... && ...` into command strings:
+
+```typescript
+await shell.execStrict('pnpm build', {
+  cwd: '/path/to/package',
+});
+
+await shell.execSpawn('git', ['status', '--short'], {
+  cwd: '/path/to/repo',
+});
+```
+
+### Environment Variables
+
+```typescript
+await shell.execSpawn('node', ['server.js'], {
+  env: {
+    ...process.env,
+    NODE_ENV: 'production',
+    PORT: '3000',
+  },
+});
+```
+
+### Timeouts
+
+Timeouts terminate the process tree with `SIGTERM`.
+
+```typescript
+const result = await shell.execSpawn('sleep', ['10'], {
+  timeout: 500,
+});
+
+console.log(result.signal); // SIGTERM on typical POSIX platforms
+```
+
+### Bounded Output Buffers
+
+Regular shell and spawn executions keep a combined output buffer. `maxBuffer` limits that buffer and replaces it with a truncation marker if the limit is exceeded.
+
+```typescript
+const result = await shell.exec('long-running-output-command', {
+  maxBuffer: 10 * 1024 * 1024,
+  onData: (chunk) => {
+    // Stream chunks elsewhere while smartshell protects its own buffer.
+    process.stdout.write(chunk);
+  },
+});
+```
+
+### Debug Logging
+
+```typescript
+const streaming = await shell.execSpawnStreaming('sleep', ['30'], {
+  debug: true,
+});
+
+await streaming.terminate();
+await streaming.finalPromise;
+```
+
+## Results and Errors
+
+### `IExecResult`
+
+```typescript
+interface IExecResult {
+  exitCode: number;
+  stdout: string;
+  combinedOutput?: string;
+  signal?: NodeJS.Signals;
+  stderr?: string;
+}
+```
+
+Important: `stdout` intentionally preserves smartshell's legacy behavior and contains the combined stdout/stderr buffer. Use `stderr` when you need stderr separately, and use `combinedOutput` when you want to make that combined-buffer behavior explicit in your own code.
+
+### `SmartshellError`
+
+Strict methods reject with `SmartshellError` and expose the command result details directly:
+
+```typescript
+class SmartshellError extends Error {
+  command: string;
+  result: IExecResult;
+  exitCode: number;
+  stdout: string;
+  combinedOutput?: string;
+  stderr?: string;
+  signal?: NodeJS.Signals;
+}
+```
+
+### Streaming and Interactive Results
+
+```typescript
+interface IExecResultStreaming {
+  childProcess: import('child_process').ChildProcess;
+  finalPromise: Promise<IExecResult>;
+  kill: () => Promise<void>;
+  terminate: () => Promise<void>;
+  keyboardInterrupt: () => Promise<void>;
+  customSignal: (signal: string) => Promise<void>;
+  sendInput: (input: string) => Promise<void>;
+  sendLine: (line: string) => Promise<void>;
+  endInput: () => void;
+}
+
+interface IExecResultInteractive extends IExecResult {
+  sendInput: (input: string) => Promise<void>;
+  sendLine: (line: string) => Promise<void>;
+  endInput: () => void;
+  finalPromise: Promise<IExecResult>;
+}
+```
+
+## Waiting for Output
+
+`execAndWaitForLine()` starts a streaming command and resolves when stdout matches a regular expression.
+
+```typescript
+await shell.execAndWaitForLine(
+  'pnpm dev',
+  /Server listening on port 3000/,
+  false,
+  {
+    timeout: 30_000,
+    terminateOnMatch: true,
+    cwd: '/path/to/app',
+  }
+);
+```
+
+Use `execAndWaitForLineSilent()` to suppress automatic output:
+
+```typescript
+await shell.execAndWaitForLineSilent('node server.js', /ready/, {
+  timeout: 10_000,
+});
+```
+
+If the process ends before a match or the timeout expires, the promise rejects.
+
+## Environment Customization
+
+`ShellEnv` is available through each `Smartshell` instance as `shell.shellEnv`. It lets you source files and add PATH directories before shell-based command strings execute.
+
+```typescript
+const shell = new Smartshell({
+  executor: 'bash',
+  sourceFilePaths: ['/opt/project/env.sh'],
+  pathDirectories: ['/opt/project/bin'],
+});
+
+shell.shellEnv.addSourceFiles(['./local.env.sh']);
+shell.shellEnv.pathDirArray.push('/custom/bin');
+
+await shell.exec('my-tool --version');
+```
+
+`ShellEnv` also imports the current `PATH` and appends `SMARTSHELL_PATH` when that environment variable is set. On WSL it filters Windows path entries that commonly break POSIX shell execution.
+
+## SmartExecution
+
+`SmartExecution` is a tiny restart helper for long-running commands such as development servers. It lazily creates its own bash-backed `Smartshell` and keeps one streaming execution active.
+
+```typescript
+import { SmartExecution } from '@push.rocks/smartshell';
+
+const devServer = new SmartExecution('pnpm dev');
+
+await devServer.restart(); // starts the command
+await devServer.restart(); // kills the current process tree and starts it again
+```
+
+If multiple restarts are requested while a restart is already in progress, they are collapsed into one additional restart.
+
+## Command Discovery
+
+The package re-exports `which` for checking whether an executable is available.
+
+```typescript
+import { which } from '@push.rocks/smartshell';
+
+const gitPath = await which('git');
+console.log(gitPath);
+```

+
+## Security Guide
+
+Command execution is powerful and dangerous when untrusted input is involved. The rule is simple: use shell-based APIs for trusted command strings, and use spawn APIs for untrusted arguments.
+
+### Prefer Spawn for Untrusted Data
+
+```typescript
+// Do not do this with untrusted values.
+await shell.exec(`git checkout ${branchFromRequest}`);
+
+// Do this instead.
+await shell.execSpawn('git', ['checkout', branchFromRequest]);
+```
+
+### Avoid Shell-Built Paths
+
+```typescript
+// Risky if pathFromUser contains shell syntax.
+await shell.exec(`cat ${pathFromUser}`);
+
+// Safer: validate the path and pass it as a literal argument.
+await shell.execSpawn('cat', [pathFromUser]);
+```
+
+### Set Resource Limits
+
+For user-triggered commands, set a timeout and a sensible buffer limit:
+
+```typescript
+await shell.execSpawn('convert', [inputPath, outputPath], {
+  timeout: 60_000,
+  maxBuffer: 20 * 1024 * 1024,
+  silent: true,
+});
+```
+
+### Control the Environment
+
+Pass an explicit `env` when secrets or inherited environment variables matter:
+
+```typescript
+await shell.execSpawn('node', ['worker.js'], {
+  env: {
+    PATH: process.env.PATH,
+    NODE_ENV: 'production',
+  },
+});
+```
+
+## Real-World Recipes
+
+### Build Pipeline
+
+```typescript
+const shell = new Smartshell({ executor: 'bash' });
+
+await shell.execStrict('rm -rf dist');
+await shell.execStrict('pnpm build');
+await shell.execStrict('pnpm test');
+```
+
+### Safe Git Automation
+
+```typescript
+async function checkoutAndTag(branch: string, tag: string) {
+  const shell = new Smartshell({ executor: 'bash' });
+
+  await shell.execSpawn('git', ['checkout', branch], { strict: true });
+  await shell.execSpawn('git', ['tag', tag], { strict: true });
+}
+```
+
+### Wait for a Development Server
+
+```typescript
+const server = shell.execAndWaitForLine(
+  'pnpm dev',
+  /ready|listening/i,
+  false,
+  {
+    cwd: '/path/to/app',
+    timeout: 30_000,
+  }
+);
+
+await server;
+```
+
+### Restart on File Changes
+
+```typescript
+import { watch } from 'node:fs';
+import { SmartExecution } from '@push.rocks/smartshell';
+
+const execution = new SmartExecution('pnpm dev');
+
+await execution.restart();
+
+watch('./src', { recursive: true }, async () => {
+  await execution.restart();
+});
+```
