This is an empty repo to make it easy to experiment with AtScript.
# Clone the repo...
git clone https://github.com/vojtajina/atscript-playground.git
cd atscript-playground
# Then, you need to install all the dependencies...
npm install
# If you want to be able to use global commands `karma` and `gulp`...
npm install -g karma-cli gulpOur example consists of two files:
atscript-playground/src/something.atsdefines a simple class that returns the sum of two input valuesatscript-playground/src/main.atsimports that class and prints a message to the console
To run in the browser, you need to first build the project. This creates a build/ directory that contains the transpiled *.js files that are created from your AtScript project.
# Do initial build, start a webserver and re-build on every file change...
gulp build serve watchOpen a browser and look in the console log to see the result.
The tests are in atscript-playground/test/something_spec.ats. Run them using Karma, like so:
karma startKarma opens a browser window for running tests. To see the actual test output (and errors), look for the log in the terminal window where you issued the karma start command.
Transpiles AtScript code into regular ES5 (today's JavaScript) so that it can be run in a current browser.
Traceur is configured to transpile AtScript modules into AMD syntax and we use RequireJS to load the code in the browser. This is just temporary until we improve the ES Module Loader polyfill (more details).
Assert library
When typeAssertions: true option is used, Traceur generates run-time type assertions such as assert.type(x, Object). The assert library does the actual run-time check. Of course, you can use your own assert library.
The idea with type assertions is that you only use them during the development/testing and when deploying, you use typeAssertions: false.
Test runner that runs the tests in specified browsers, every time that you change a file.
Task runner to make defining and running the tasks simpler.
