# Setting up a development environment
The following sets up a development environment of the compiler where editing the sources applies changes immediately without having to go through a build step:
git clone https://github.com/AssemblyScript/assemblyscript.git cd assemblyscript npm install npm link
Note that a development environment runs the sources directly by default, but will use distributions files once built. Cleaning the distribution files again with
npm run clean resets this. Whether
asc is running the sources or distribution files can be determined by checking the displayed version number. If it states
-dev, it runs the sources directly.
# Building distribution files
To build an UMD bundle to
dist/assemblyscript.js (depends on binaryen.js), including a browser version of asc to
dist/asc.js (depends on assemblyscript.js):
npm run build
Cleaning the distribution files (again):
npm run clean
Linting potential changes:
npm run check
Running the tests:
Running everything in order (check, clean, test, build, test):
npm run all
# Creating tests
The test suite is composed of a set of tests for each component, like the parser, the compiler and runtime. For each pull request, all the tests are run automatically and the PR only goes green if it passes all of them. Please see the instructions within the repository for all the details.
