The Mars programming language will follow a similar syntax to that of Groovy.
It will use the file extension .mars.
publicprivate
If no modifier is set, then public is assumed.
The public modifier should be used to allow global access.
The private modifier restricts access to that package only.
| Modifier | Example | Note |
|---|---|---|
| public | string name | Optionally you can do public string name |
| private | private string name |
See keywords.md.
Although they will be supported, they are not required.
To set the package all you have to do is have it in the correct directory and add the following line to the top of your source file.
package uk.jamierocks.example
Comments are defined by using //.
// This is a comment
/*
* This is a long comment
*/
A long comment is defined by it's start /* and it's end */, the content it contains can be formatted however the programmer likes.
Unlike in Java, you don't have to name the source file after the class it will contain, infact source files can have multiple classes/structs/etc. The most basic class would define a main method.
void main(string[] args) {
println("Hello, World!")
}
The following is a example of a class.
package xyz.lexteam.example // Set the package
class ExampleClass { // Set the class - see I have used no access modifier because it will default to public
private string name // Declared a private field - notice no semi-colon?
string getName() { // Declared a method - see no access modifer - again public is assumed.
return name
}
}
Unlike the likes of Java, Mars has structs.
package xyz.lexteam.example
struct Book {
string name
string author
}
You can make an instance of that struct like the following.
new xyz.lexteam.example.Book("iWoz", "Steve Wozniak")
The following is an example of a enum.
package xyz.lexteam.example
enum OperatingSystem {
OSX('mac'),
LINUX('nix'),
WINDOWS('dows');
private string identifier
OperatingSystem(string identifier) {
this.identifier = identifier
}
}
