`stdout` and `stderr` can be retrieved. 47 | 48 | ```objc 49 | [ [ SKShell currentShell ] runCommand: @"ls -al" 50 | completion: ^( int status, NSString * output, NSString * error ) 51 | { 52 | NSLog( @"%i", status );

65 | 66 | task = [ SKTask taskWithShellScript: @"ls -al" ]; 67 | 68 | [ task run ]; 69 | ``` 70 | 71 | The task is run synchronously, and its output, if any, will be automatically printed to `stdout`. 72 | 73 | The task will print the executed command prior to running, and print a status message once it's terminated, along with the elapsed time: 74 | 75 | [ ShellKit ]> 🚦 Running task: ls -al 76 | total 536 77 | drwxr-xr-x 5 macmade staff 170 May 11 23:49 . 78 | drwxr-xr-x@ 4 macmade staff 136 May 11 22:18 .. 79 | -rwxr-xr-x 1 macmade staff 124624 May 11 23:49 ShellKit-Test 80 | drwxr-xr-x 7 macmade staff 238 May 11 23:48 ShellKit.framework 81 | -rw-r--r-- 1 macmade staff 143936 May 11 23:48 libShellKit-Static.a 82 | [ ShellKit ]> ✅ Task completed successfully (63 ms) 83 | 84 | A task can have sub-tasks, to try to recover from a failure: 85 | 86 | ```objc 87 | SKTask * task;

159 | g2 = [ SKTaskGroup taskGroupWithName: @"parent-group" tasks: @[ g1 ] ]; 160 | 161 | [ g2 run ]; 162 | ``` 163 | 164 | The hierarchy of groups will be reflected by the prompt, like: 165 | 166 | [ ShellKit ]> [ parent-group ]> [ #1 ]> [ child-group ]> [ #1 ]> 🚦 Running task: true 167 | 168 | **Note that task groups can also run custom classes, as long as they conform to the `SKRunableObject` protocol.** 169 | 170 | ### Variables substitution 171 | 172 | A task may contain variables, that will be substituted when running. 173 | A variable has the following form: 174 | 175 | %{name}% 176 | 177 | The variable name may contain letters from A to Z (uppercase or lowercase) and numbers from 0 to 9. 178 | 179 | Variables are passed using the `run:` method of `SKTask` and `SKTaskGroup`. 180 | 181 | ```objc 182 | SKTask * task; 183 | 184 | task = [ SKTask taskWithShellScript: @"ls %{args}% %{dir}%" ]; 185 | 186 | [ task run: @{ @"args" : @"-al", @"dir" : @"/usr" } ]; 187 | ``` 188 | 189 | In the example above, the executed script will be: `ls -al /usr`. 190 | 191 | If no value is provided for a variable, the task will fail: 192 | 193 | ```objc 194 | SKTask * task; 195 | 196 | task = [ SKTask taskWithShellScript: @"echo %{hello}% %{foo}% %{bar}%" ]; 197 | 198 | [ task run: @{ @"hello" : @"hello, world" } ]; 199 | ``` 200 | 201 | [ ShellKit ]> 🚦 Running task: echo hello, world %{foo}% %{bar}% 202 | [ ShellKit ]> ⚠️ No value provided value for variable: foo 203 | [ ShellKit ]> ⚠️ No value provided value for variable: bar 204 | [ ShellKit ]> ❌ Error - Script contains unsubstituted variables 205 | 206 | ### Printing messages 207 | 208 | Messages can be printed very easily. 209 | For this purpose, the `SKShell` class provides several methods, like the following one: 210 | 211 | 212 | ```objc 213 | - ( void )printMessage: ( NSString * )format 214 | status: ( SKStatus )status 215 | color: ( SKColor )color, 216 | ...; 217 | ``` 218 | 219 | The status represents an optional icon. 220 | Colors can also be used, if the terminal supports it. 221 | 222 | As an example: 223 | 224 | ```objc 225 | [ [ SKShell currentShell ] printMessage: @"hello, %@" 226 | status: SKStatusDebug 227 | color: SKColorCyan, 228 | @"world" 229 | ]; 230 | ``` 231 | 232 | will produce: 233 | 234 | 🚸 hello, world 235 | 236 | ### Customising prompt 237 | 238 | The prompt can be customised to reflect the hierarchy of the invoked commands. 239 | 240 | For instance: 241 | 242 | ```objc 243 | [ SKShell currentShell ].promptParts = @[ @"foo", @"bar" ]; 244 | ``` 245 | 246 | Then, every printed message will be prefixed by: 247 | 248 | [ foo ]> [ bar ]> ... message ... 249 | 250 | License 251 | ------- 252 | 253 | ShellKit is released under the terms of the MIT license. 254 | 255 | Repository Infos 256 | ---------------- 257 | 258 | Owner: Jean-David Gadina - XS-Labs 259 | Web: www.xs-labs.com 260 | Blog: www.noxeos.com 261 | Twitter: @macmade 262 | GitHub: github.com/macmade 263 | LinkedIn: ch.linkedin.com/in/macmade/ 264 | StackOverflow: stackoverflow.com/users/182676/macmade 265 | -------------------------------------------------------------------------------- /ShellKit-Test/main.m: -------------------------------------------------------------------------------- 1 | /******************************************************************************* 2 | * The MIT License (MIT) 3 | * 4 | * Copyright (c) 2017 Jean-David Gadina - www.xs-labs.com 5 | * 6 | * Permission is hereby granted, free of charge, to any person obtaining a copy 7 | * of this software and associated documentation files (the "Software"), to deal 8 | * in the Software without restriction, including without limitation the rights 9 | * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 10 | * copies of the Software, and to permit persons to whom the Software is 11 | * furnished to do so, subject to the following conditions: 12 | * 13 | * The above copyright notice and this permission notice shall be included in 14 | * all copies or substantial portions of the Software. 15 | * 16 | * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 17 | * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 18 | * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
