var common = require('./src/common');

//@
//@ All commands run synchronously, unless otherwise stated.
//@ All commands accept standard bash globbing characters (`*`, `?`, etc.),
//@ compatible with the [node glob module](https://github.com/isaacs/node-glob).
//@
//@ For less-commonly used commands and features, please check out our [wiki
//@ page](https://github.com/shelljs/shelljs/wiki).
//@

// Include the docs for all the default commands
//@commands

// Load all default commands
require('./commands.json').forEach(function (command) {
  require('./src/' + command);
});

//@
//@ ### exit(code)
//@ Exits the current process with the given exit code.
exports.exit = process.exit;

//@include ./src/error
exports.error = require('./src/error');

//@include ./src/common
exports.ShellString = common.ShellString;

//@
//@ ### env['VAR_NAME']
//@ Object containing environment variables (both getter and setter). Shortcut
//@ to process.env.
exports.env = process.env;

//@
//@ ### Pipes
//@
//@ Examples:
//@
//@ ```javascript
//@ grep('foo', 'file1.txt', 'file2.txt').sed(/o/g, 'a').to('output.txt');
//@ echo('files with o\'s in the name:\n' + ls().grep('o'));
//@ cat('test.js').exec('node'); // pipe to exec() call
//@ ```
//@
//@ Commands can send their output to another command in a pipe-like fashion.
//@ `sed`, `grep`, `cat`, `exec`, `to`, and `toEnd` can appear on the right-hand
//@ side of a pipe. Pipes can be chained.

//@
//@ ## Configuration
//@

exports.config = common.config;

//@
//@ ### config.silent
//@
//@ Example:
//@
//@ ```javascript
//@ var sh = require('shelljs');
//@ var silentState = sh.config.silent; // save old silent state
//@ sh.config.silent = true;
//@ /* ... */
//@ sh.config.silent = silentState; // restore old silent state
//@ ```
//@
//@ Suppresses all command output if `true`, except for `echo()` calls.
//@ Default is `false`.

//@
//@ ### config.fatal
//@
//@ Example:
//@
//@ ```javascript
//@ require('shelljs/global');
//@ config.fatal = true; // or set('-e');
//@ cp('this_file_does_not_exist', '/dev/null'); // throws Error here
//@ /* more commands... */
//@ ```
//@
//@ If `true` the script will throw a Javascript error when any shell.js
//@ command encounters an error. Default is `false`. This is analogous to
//@ Bash's `set -e`

//@
//@ ### config.verbose
//@
//@ Example:
//@
//@ ```javascript
//@ config.verbose = true; // or set('-v');
//@ cd('dir/');
//@ ls('subdir/');
//@ ```
//@
//@ Will print each command as follows:
//@
//@ ```
//@ cd dir/
//@ ls subdir/
//@ ```

//@
//@ ### config.globOptions
//@
//@ Example:
//@
//@ ```javascript
//@ config.globOptions = {nodir: true};
//@ ```
//@
//@ Use this value for calls to `glob.sync()` instead of the default options.

//@
//@ ### config.reset()
//@
//@ Example:
//@
//@ ```javascript
//@ var shell = require('shelljs');
//@ // Make changes to shell.config, and do stuff...
//@ /* ... */
//@ shell.config.reset(); // reset to original state
//@ // Do more stuff, but with original settings
//@ /* ... */
//@ ```
//@
//@ Reset shell.config to the defaults:
//@
//@ ```javascript
//@ {
//@   fatal: false,
//@   globOptions: {},
//@   maxdepth: 255,
//@   noglob: false,
//@   silent: false,
//@   verbose: false,
//@ }
//@ ```
