Mojito Command Line¶

Mojito comes with a command-line tool that provides a number of key capabilities for the developer, from generating code skeletons, to running tests and test coverage, to cleaning up and documenting the code base.

All commands except mojito create must be run from within the application directory.

Help¶

To show top-level help for this command line tool:

$ mojito help

To show help for a specific command:

$ mojito help <command>

Creating Code from Archetypes¶

Archetypes are used to create skeletons for the different types of artifacts in a Mojito application. The skeletons only contain stripped down boilerplate code that is easier to create using the command-line tool rather than by hand.

To create a skeleton for a Mojito application:

$ mojito create app [<archetype-name>] <path/to/app-name>

This will create an empty application (i.e., one with no mojits) with the name provided. The application is created in a directory named <app-name> within the specified directory. If no archetype name is provided, the default archetype is used.
From the application directory, use the following command to create a skeleton for a mojit:

$ mojito create mojit [<archetype-name>] <mojit-name>

This will create an empty mojit with the name provided. The command assumes it is being executed within an application directory. Thus, the mojit is created in a directory named <mojit-name> within a mojits subdirectory of the application directory. For example, the mojit MyMojit would be created in mojits/MyMojit.

As with application creation, if no archetype name is provided, the default archetype is used. Depending upon the archetype, the skeleton may include any or all of the controller, model, view, and binder.

Mojito Archetypes¶

Mojito offers the following three archetypes for applications and mojits.

simple - The minimal configuration and code needed to run an application.
default - This archetype is run if no command-line archetype option is specified. It is a happy medium between simple and full.
demo - This archetype is only availabe for applications, but let’s you create demo applications. The built-in demo application is the quickstart application that serves documentation and serves as an example application.
full - Provides the most comprehensive configuration and code for applications.

Custom Archetypes¶

You can also customize archetypes and then use them to generate code. For example, if you customized the template code that Mojito uses (or create your own) to generate boilerplate code, such as an application or a mojit, you could have Mojito use your archetype to generate code with the following command:

$ mojito create mojit <archetype-path> <generated_code-path>

For example: $ mojito create app ./my_archetypes/mobile_web_app ./my_apps/micro_blog

Testing¶

Unit tests are run using YUI Test invoked using the Mojito command-line tool. Test output is written to the console and also to the file {CWD}/artifacts/test/result.xml, where {CWD} is the current working directory. Note when you run tests, the output may overwrite the results of past tests. To avoid this, you can use the long option --directory or an abbreviation such as --dir to to specify where to write test results.

To run tests for an application:

$ mojito test [app] [.]
To run the unit tests for a specific mojit, use one of the following:
- $ mojito test mojit <mojit-path>
- $ mojito test mojit <mojit-name>
To run the unit tests for one or more modules of a mojit, use one of the following:
- $ mojito test mojit <mojit-path> --testname <mojit-module1> --testname <mojit-module2> --testname <mojit-module3>
- $ mojito test mojit <mojit-path> <mojit-module1>,<mojit-module2>,<mojit-module3>
If one or more mojit modules (i.e., the YUI modules for a portion of the mojit) are specified, only the tests for those modules will be run. Otherwise all tests for the mojit will be run.
To specify the output directory for test results:
- $ mojito test [app] --directory <test_results-path>
- $ mojito test mojit <mojit-path> --dir <test_results-path>

To run functional and unit tests for the Mojito framework, you would use the test framework Yahoo Arrow. Follow the instructions in Running Mojito’s Built-In Tests to run the framework tests for Mojito.

Code Coverage¶

Code coverage is invoked in the same way as unit testing, but with the added option --coverage or -c. To run code coverage tests, you need to have Java installed. You can specify where to write the coverage results using the option --directory or --dir. Coverage results are written to the directory {CWD}/artifacts/test/coverage/ by default. You can also specify the path to write results with the long option --directory or an abbreviation such as --dir (see example below).

To run code coverage for a Mojito application:

$ mojito test [app] --coverage
To run code coverage for a specific mojit:

$ mojito test -c [mojit] <mojit-path>
To specify the output directory for test results:
- $ mojito test [app] -c --directory <path>
- $ mojito test mojit -c <mojit-path> --dir <path>
The coverage results will be written to <path>/coverage/.

Starting the Server¶

Use the following to start the server and run the application.

$ node app.js

Note

Mojito v0.8 and earlier used the Mojito CLI utility to start applications (mojito start). If you have an older application you need to create an app.js first and then use node app.js to start the application.

Sanitizing Code¶

Static code analysis is run using JSLint invoked using the Mojito command-line tool. By default, the JSLint error report is written to {CWD}/artifacts/jslint/jslint.html. You can also specify the directory to write the error report to with the long option --directory or an abbreviation such as --dir.

To run JSLint on the Mojito framework code:

$ mojito jslint mojito
To run JSLint on an application, including its mojits:

$ mojito jslint app .
To run JSLint on a specific mojit:

$ mojito jslint mojit <mojit-path>
To run JSLInt on all the files in a path:

$ mojito jslint [<path>]
To write the error report to a specific directory:

$ mojito jslint app . --dir <path>

Documenting Code¶

API documentation is generated using YUI Doc, which is invoked using the Mojito command-line tool. Documentation output is written to files in the locations specified below. Because it’s based on YUI Doc, you can start a server that displays the documentation with the option --server and specify a port with --port. You can also specify the output directory with the the option --directory or an abbreviation such as --dir.

To generate documentation for the Mojito framework itself:

$ mojito docs mojito

Output is written to {CWD}/artifacts/docs/mojito/, where {CWD} is the current working directory.
To generate documentation for an application, including all of its (owned) mojits, run the following from the application directory:

$ mojito docs app

Output is written to {app-dir}/artifacts/docs/.
To generate documentation for a specific mojit, run one of the following:
- $ mojito docs mojit <mojit-path>
- $ mojito docs mojit <mojit-name>
Output is written to {app-dir}/artifacts/docs/mojits/{mojit-name}/.
To start a server for the documentation:

$ mojito docs app --server [--port <port_number>]

Version Information¶

To display the version of the mojito-cli package:

$ mojito version
To show the version of an application and the locally installed version of Mojito:

$ mojito version app
To show the version for a mojit, run the following from the application directory:

$ mojito version mojit <mojit-name>

Note

Showing the version of the application and mojit requires that they have a package.json file.

Dependency Graphs (Deprecated)¶

The command below generates the Graphviz file {CWD}/artifacts/gv/yui.client.dot ({CWD} represents the current working directory) that describes the YUI module dependencies.

$ mojito gv

The mojito gv command has the following options:

--client - inspects the files that have client and common as the affinity. The default is just to inspect files that have server and common as the affinity. For example, using the --client option, the file controller.client.js and controller.common.js will be inspected.
--framework - also inspects the Mojito framework files.

Note

To render the Graphviz files into GIF images, you need the Graphviz - Graph Visualization Software.

No Longer Supported¶

As of Mojito v0.9, several command-line features are no longer supported. The following sections discuss what’s not supported and offer possible solutions.

mojito start¶

Applications are no longer started with mojito start. You start applications with node and the boot file app.js:

$ node app.js

mojito build¶

As of Mojito v0.9, the build command for creating HTML5 applications from Mojito applications is no longer available.

Specifying Context: –context¶

You can no longer specify the base context with the --context option. To specify a base context in Mojito v0.9 and later, you pass a context object to the extend method in the file app.js. In the example snippet from app.js below, the application when started will use the base context environment:staging:

var express = require('express'),
    libmojito = require('mojito'),
    app = express();

libmojito.extend(app, {
    context: {
        runtime: 'server',
        environment: 'staging'
    }
});
