# scala-native-example-app
An example project showing how to use Scala-Native in SBT, together with third
party libraries (in this case [Scalatags](https://github.com/lihaoyi/scalatags))
and a test suite (using [uTest](https://github.com/lihaoyi/utest)).
## Using this project
You should be able to import this project into IntelliJ-IDEA or any other Scala
IDE or editor without issue.
To build an executable without running:
```
$ ./mill show example.nativeLink
...
"out/example/nativeLink/dest/out"
```
To then run that executable:
```
$ out/example/nativeLink/dest/out --help
JSON Reformatter
Pretty-print JSON or minify it
--src Source file to load JSON from; defaults to stdin if not given
--dest Destination file to write JSON to; defaults to stdout if not given
--indent Indentation to pretty-print the JSON with; default 4, pass -1 to minify instead
$ echo [1, 2, 3] | out/example/nativeLink/dest/out --dest out.json
[
1,
2,
3
]
$ echo [1, 2, 3] | out/example/nativeLink/dest/out --indent -1
[1,2,3]
$ echo [1, 2, 3] | out/example/nativeLink/dest/out --dest out.json
$ cat out.json
[
1,
2,
3
]
```
The executable should run instantly, without the ~1s startup overhead you may be
used to with Scala programs running on the JVM.
```
$ time out/example/nativeLink/dest/out --help
...
real 0m0.009s
user 0m0.003s
sys 0m0.003s
```
To run tests:
```
$ ./mill example.test
...
-------------------------------- Running Tests --------------------------------
+ example.ExampleTests.minified 0ms
+ example.ExampleTests.indent0 0ms
+ example.ExampleTests.indent2 0ms
```
You can of course use the full functionality of uTest to
[select which tests to run](https://github.com/lihaoyi/utest#running-tests).
