- "make all" builds all combinations of configurations - Binaries are built to "bin" - (For convenience, the release interpreter also goes in the top level dir) - Libraries are built to "lib" This will also make it easier to support building and testing other configurations like Nan tagging versus union, computed goto, etc.

^title Getting Started
|
|
|
|
Getting Wren up and running on your machine should be pretty straightforward.
|
|
Tiny C programs with no dependencies are nice that way. If you're on a Unix or
|
|
Mac and you can rock a command line, it's just:
|
|
|
|
:::bash
|
|
$ git clone https://github.com/munificent/wren.git
|
|
$ cd wren
|
|
$ make
|
|
$ ./wren
|
|
|
|
Binaries for other configurations are built to `bin/`. Static and shared
|
|
libraries for embedding Wren get built in `lib/`.
|
|
|
|
For Mac users, there is also an XCode project under `project/xcode`. For
|
|
Windows brethren, `project/msvc2013` contains a Visual Studio solution. Note
|
|
that these may not have the exact same build settings as the makefile. The
|
|
makefile is the "official" way to compile Wren.
|
|
|
|
## Interactive mode
|
|
|
|
The above instructions will drop you into Wren's standalone interpreter in
|
|
interactive mode. You can type in a line of code, and it will immediately
|
|
execute it. Here's something to try:
|
|
|
|
:::dart
|
|
IO.print("Hello, world!")
|
|
|
|
Or a little more exciting:
|
|
|
|
:::dart
|
|
for (i in 1..10) IO.print("Counting up ", i)
|
|
|
|
You can exit the interpreter using good old Ctrl-C or Ctrl-D, or just throw
|
|
your computer to the ground and storm off.
|
|
|
|
## Running scripts
|
|
|
|
The standalone interpreter can also load scripts from files and run them. Just
|
|
pass the name of the script to wren. Create a file named "my_script.wren" in
|
|
your favorite text editor and paste this into it:
|
|
|
|
:::dart
|
|
for (yPixel in 0...24) {
|
|
var y = yPixel / 12 - 1
|
|
for (xPixel in 0...80) {
|
|
var x = xPixel / 30 - 2
|
|
var x0 = x
|
|
var y0 = y
|
|
var iter = 0
|
|
while (iter < 11 && x0 * x0 + y0 * y0 <= 4) {
|
|
var x1 = (x0 * x0) - (y0 * y0) + x
|
|
var y1 = 2 * x0 * y0 + y
|
|
x0 = x1
|
|
y0 = y1
|
|
iter = iter + 1
|
|
}
|
|
IO.write(" .-:;+=xX$& "[iter])
|
|
}
|
|
|
|
IO.print("")
|
|
}
|
|
|
|
Now run:
|
|
|
|
:::bash
|
|
$ ./wren my_script.wren
|
|
|
|
Neat, right? You're a Wren programmer now! The next step is to [read more
|
|
docs](syntax.html) and learn your way around the language. If you run into
|
|
bugs, or have ideas or questions, any of the following work:
|
|
|
|
* **Ask on the [Wren mailing list][list].**
|
|
* Tell me on twitter at [@munificentbob][twitter].
|
|
* [File a ticket][issue] at [the GitHub repo][repo].
|
|
* Send a pull request.
|
|
* Email me at [`robert@stuffwithstuff.com`](mailto:robert@stuffwithstuff.com).
