Specifying the Object to this argument has the more merit.

A function is chosen properly by handling case of the command-name in accordance with the [`caseSensitive`](#basic_options-casesensitive) option. +The function is called with a parsed Array that excludes a command-name (i.e. first element is removed from the Array) as an argument list of the function. +That is, a structure of the `commandHandler` Object looks like: + +```js +{ + commandA: function(arg) { ... }, // commandA requires one argument. + commandB: function(arg1, arg2) { ... }, // readlineSync doesn't care those. + commandC: function() { ... } // Of course, it can also ignore all. +} +``` + +readlineSync just receives the arguments from the user and passes those to these functions without checking. The functions may have to check whether the required argument was input by the user, and more validate those. + +For example, the following code works same to the above code: + +```js +readlineSync.promptCL({ + add: function(element) { // It's called by also "ADD", "Add", "aDd", etc.. + console.log(element + ' is added.'); + }, + copy: function(from, to) { + console.log(from + ' is copied to ' + to + '.'); + } +}); +``` + +If the matched property is not found in the Object, a `_` property is chosen, and the function as the value of this property is called with a parsed Array as an argument list of the function. Note that this includes a command-name. That is, the function looks like `function(command, arg1, arg2, ...) { ... }`. +And if the Object doesn't have a `_` property, any command that the matched property is not found in the Object is refused. + +For example: + +```js +readlineSync.promptCL({ + copy: function(from, to) { // command-name is not included. + console.log(from + ' is copied to ' + to + '.'); + }, + _: function(command) { // command-name is included. + console.log('Sorry, ' + command + ' is not available.'); + } +}); +``` + +#### Options + +The following options have independent default value that is not affected by [Default Options](#basic_options). + +| Option Name | Default Value | +|-------------------|---------------| +| [`hideEchoBack`](#basic_options-hideechoback) | `false` | +| [`limitMessage`](#basic_options-limitmessage) | `'Requested command is not available.'` | +| [`caseSensitive`](#basic_options-casesensitive) | `false` | +| [`history`](#basic_options-history) | `true` | + +The following options work as shown in the [Basic Options](#basic_options) section. + + + + +

If you want to put a `'$'` which is *not* an escape character at the left of a placeholder, specify it like `'$<($)bufferSize>'`, then it is replaced to `'$1024'`. + +At the each position of `'(text1)'` and `'(text2)'`, `'text1'` and `'text2'` are put when a string that was got by a `parameter` has more than 0 length. If that got string is `''`, a placeholder with or without `'(text1)'` and `'(text2)'` is replaced to `''`. + +For example, a warning message that means that the command the user requested is not available: + +```js +command = readlineSync.prompt({ + limit: ['add', 'remove'], + limitMessage: 'Refused $ you requested.

Please input another.' +}); +``` + +```console +> +Refused . Please input another. +``` + +(May be more better: `'$<(Refused )lastInput( you requested. )>Please input another.'`) + +**Note:** The syntax `${parameter}` of older version is still supported, but this should not be used because it may be confused with template string syntax of ES6.

The boolean value is replaced to `'on'` or `'off'`, and the Array is replaced to the list of only string and number elements. +And in the `keyIn*` method, the parts of the list as characters sequence are suppressed. For example, when `['a', 'b', 'c', 'd', 'e']` is specified to the [`limit`](#basic_options-limit) option, `'$'` is replaced to `'a...e'`. If `true` is specified to the [`caseSensitive`](#basic_options-casesensitive) option, the characters are converted to lower case. + +For example: + +```js +input = readlineSync.question( + 'Input something or the Enter key as "$": ', + {defaultInput: 'hello'} +); +``` + +```console +Input something or the Enter key as "hello": +``` + +#### `limitCount`, `limitCountNotZero` + +A length of a current value of the [`limit`](#basic_options-limit) option. +When the value of the [`limit`](#basic_options-limit) option is empty, `'$'` is replaced to `'0'`, `'$'` is replaced to `''`. + +For example: + +```js +action = readlineSync.question( + 'Choose action$<( from )limitCountNotZero( actions)>: ', + {limit: availableActions} +); +``` + +```console +Choose action from 5 actions: +``` + +#### `lastInput` + +A last input from the user. +In any case, this is saved. + +For example: + +```js +command = readlineSync.prompt({ + limit: availableCommands, + limitMessage: '$ is not available.' +}); +``` + +```console +> wrong-command +wrong-command is not available. +``` + +#### `history_mN` + +When the history expansion feature is enabled (see [`history`](#basic_options-history) option), a current command line minus `N`. +*This feature keeps the previous input only.* That is, only `history_m1` is supported. + +For example: + +```js +while (true) { + input = readlineSync.question('Something$<( or "!!" as ")history_m1(")>: '); + console.log('-- You said "' + input + '"'); +} +``` + +```console +Something: hello +-- You said "hello" +Something or "!!" as "hello": !! +hello +-- You said "hello" +``` + +#### `cwd`, `CWD`, `cwdHome` + +A current working directory. + +* `cwd`: A full-path +* `CWD`: A directory name +* `cwdHome`: A path that includes `~` as the home directory + +For example, like bash/zsh: + +```js +command = readlineSync.prompt({prompt: '[$]$ '}); +``` + +```console +[~/foo/bar]$ +``` + +#### `date`, `time`, `localeDate`, `localeTime` + +A string as current date or time. + +* `date`: A date portion +* `time`: A time portion +* `localeDate`: A locality sensitive representation of the date portion based on system settings +* `localeTime`: A locality sensitive representation of the time portion based on system settings + +For example: + +```js +command = readlineSync.prompt({prompt: '[$]> '}); +``` + +```console +[04/21/2015]> +``` + +#### `C1-C2` + +_For [`limit` option for `keyIn*` method](#basic_options-limit-for_keyin_method) and [`charlist`](#utility_methods-questionnewpassword-options-charlist) option for [`questionNewPassword`](#utility_methods-questionnewpassword) method only_ + +A character list. +`C1` and `C2` are each single character as the start and the end.

But you should understand each environments for that. Or, **you should not use this** if your script is used in multiple environments. +For example, when the user input `EOF` (`^D` in Unix like system, `^Z` in Windows), `x1A` (`EOF`) is returned in Windows, and `x00` (`NULL`) is returned in Unix like system. And `x04` (`EOT`) is returned in Unix like system with raw-mode. And also, when [external program](#note-reading_by_external_program) is used, nothing is returned. See also [Control characters](#note-control_characters). +You may examine each environment and you must test your script very much, if you want to handle the raw input data. + +## With Task Runner + +The easy way to control a flow of the task runner by the input from the user: + +* [Grunt](http://gruntjs.com/) plugin: [grunt-confirm](https://github.com/anseki/grunt-confirm) +* [gulp](http://gulpjs.com/) plugin: [gulp-confirm](https://github.com/anseki/gulp-confirm) + +If you want to control a flow of the task runner (e.g. [Grunt](http://gruntjs.com/)), call readlineSync in a task callback that is called by the task runner. Then a flow of tasks is paused and it is controlled by the user. + +For example, by using [grunt-task-helper](https://github.com/anseki/grunt-task-helper): + +```console +$ grunt +Running "fileCopy" task +Files already exist: + file-a.png + file-b.js +Overwrite? [y/n]: y +file-a.png copied. +file-b.js copied. +Done. +``` + +`Gruntfile.js` + +```js +grunt.initConfig({ + taskHelper: { + fileCopy: { + options: { + handlerByTask: function() { + // Abort the task if user don't want it. + return readlineSync.keyInYN('Overwrite?'); + }, + filesArray: [] + }, + ... + } + }, + copy: { + fileCopy: { + files: '<%= taskHelper.fileCopy.options.filesArray %>' + } + } +}); +``` + +## Note + +### Platforms + +TTY interfaces are different by the platforms. If the platform doesn't support the interactively reading from TTY, an error is thrown. + +```js +try { + answer = readlineSync.question('What is your favorite food? '); +} catch (e) { + console.error(e); + process.exit(1); +} +``` + +### Control characters + +TTY interfaces are different by the platforms. In some environments, ANSI escape sequences might be ignored. For example, in non-POSIX TTY such as Windows CMD does not support it (that of Windows 8 especially has problems). Since readlineSync does not use Node.js library that emulates POSIX TTY (but that is still incomplete), those characters may be not parsed. Then, using ANSI escape sequences is not recommended if you will support more environments. +Also, control characters user input might be not accepted or parsed. That behavior differs depending on the environment. And current Node.js does not support controlling a readline system library. + +### Reading by external program + +readlineSync tries to read from a console by using the external program if it is needed (e.g. when the input stream is redirected on Windows XP). And if the running Node.js doesn't support the [Synchronous Process Execution](http://nodejs.org/api/child_process.html#child_process_synchronous_process_creation) (i.e. Node.js v0.10-), readlineSync uses "piping via files" for the synchronous execution. +As everyone knows, "piping via files" is no good. It blocks the event loop and a process. It might make the your script be slow. + +Why did I choose it? : + +* Good modules (native addon) for the synchronous execution exist, but node-gyp can't compile those in some platforms or Node.js versions. +* I think that the security is important more than the speed. Some modules have problem about security. Those don't protect the data. I think that the speed is not needed usually, because readlineSync is used while user types keys. + +## Deprecated methods and options + +See [README-Deprecated.md](README-Deprecated.md). diff --git a/z1-prototype/node_modules/readline-sync/lib/encrypt.js b/z1-prototype/node_modules/readline-sync/lib/encrypt.js new file mode 100644 index 0000000..d732ce6 --- /dev/null +++ b/z1-prototype/node_modules/readline-sync/lib/encrypt.js @@ -0,0 +1,24 @@ +/* + * readlineSync + * https://github.com/anseki/readline-sync + * + * Copyright (c) 2019 anseki + * Licensed under the MIT license. + */ + +var cipher = require('crypto').createCipher( + process.argv[2] /*algorithm*/, process.argv[3] /*password*/), + stdin = process.stdin, + stdout = process.stdout, + crypted = ''; + +stdin.resume(); +stdin.setEncoding('utf8'); +stdin.on('data', function(d) { + crypted += cipher.update(d, 'utf8', 'hex'); +}); +stdin.on('end', function() { + stdout.write(crypted + cipher.final('hex'), 'binary', function() { + process.exit(0); + }); +}); diff --git a/z1-prototype/node_modules/readline-sync/lib/read.cs.js b/z1-prototype/node_modules/readline-sync/lib/read.cs.js new file mode 100644 index 0000000..cc31801 --- /dev/null +++ b/z1-prototype/node_modules/readline-sync/lib/read.cs.js @@ -0,0 +1,123 @@ +/* jshint wsh:true */ + +/* + * readlineSync + * https://github.com/anseki/readline-sync + * + * Copyright (c) 2019 anseki + * Licensed under the MIT license. + */ + +var + FSO_ForReading = 1, FSO_ForWriting = 2, + PS_MSG = 'Microsoft Windows PowerShell is required.' + + ' https://technet.microsoft.com/en-us/library/hh847837.aspx', + + input = '', fso, tty, + options = (function(conf) { + var options = {}, arg, args =// Array.prototype.slice.call(WScript.Arguments), + (function() { + var args = [], i, iLen; + for (i = 0, iLen = WScript.Arguments.length; i < iLen; i++) + { args.push(WScript.Arguments(i)); } + return args; + })(), + confLc = {}, key; + + function decodeArg(arg) { + return arg.replace(/#(\d+);/g, function(str, charCode) { + return String.fromCharCode(+charCode); + }); + } + + for (key in conf) { + if (conf.hasOwnProperty(key)) + { confLc[key.toLowerCase()] = {key: key, type: conf[key]}; } + } + + while (typeof(arg = args.shift()) === 'string') { + if (!(arg = (arg.match(/^\-+(.+)$/) || [])[1])) { continue; } + arg = arg.toLowerCase(); + if (confLc[arg]) { + options[confLc[arg].key] = + confLc[arg].type === 'boolean' ? true : + confLc[arg].type === 'string' ? args.shift() : null; + } + } + for (key in conf) { + if (conf.hasOwnProperty(key) && conf[key] === 'string') { + if (typeof options[key] !== 'string') { options[key] = ''; } + else { options[key] = decodeArg(options[key]); } + } + } + return options; + })({ + display: 'string', + displayOnly: 'boolean', + keyIn: 'boolean', + hideEchoBack: 'boolean', + mask: 'string' + }); + +if (!options.hideEchoBack && !options.keyIn) { + if (options.display) { writeTTY(options.display); } + if (!options.displayOnly) { input = readByFSO(); } +} else if (options.hideEchoBack && !options.keyIn && !options.mask) { + if (options.display) { writeTTY(options.display); } + if (!options.displayOnly) { input = readByPW(); } +} else { + WScript.StdErr.WriteLine(PS_MSG); + WScript.Quit(1); +} + +WScript.StdOut.Write('\'' + input + '\''); + +WScript.Quit(); + +function writeTTY(text) { + try { + tty = tty || getFso().OpenTextFile('CONOUT$', FSO_ForWriting, true); + tty.Write(text); + } catch (e) { + WScript.StdErr.WriteLine('TTY Write Error: ' + e.number + + '\n' + e.description + '\n' + PS_MSG); + WScript.Quit(e.number || 1); + } +} + +function readByFSO() { + var text; + try { + text = getFso().OpenTextFile('CONIN$', FSO_ForReading).ReadLine(); + } catch (e) { + WScript.StdErr.WriteLine('TTY Read Error: ' + e.number + + '\n' + e.description + '\n' + PS_MSG); + WScript.Quit(e.number || 1); + } + return text; +} + +// TTY must be STDIN that is not redirected and not piped. +function readByPW() { + var text; + try { + text = WScript.CreateObject('ScriptPW.Password').GetPassword() + // Bug?
