Jik v0.1.0-alpha.18
Jik v0.1.0-alpha.18 is now available. This release makes ordinary struct-related functions more pleasant to call, completes try propagation for calls without a result, and adds useful standard-library helpers.
Uniform function calls for structs
A function defined alongside a struct can now be called through a value of that struct when its first parameter is explicitly annotated with the struct type. This is method-like syntax for an ordinary function call: the receiver becomes the first argument. Calls can also be naturally chained when a function returns another struct value.
struct Vec2:
x: double
y: double
end
func scale(v: Vec2, fact: double, r: Region) -> Vec2:
return Vec2{x = v.x * fact, y = v.y * fact}[r]
end
func squared_norm(v: Vec2) -> double:
return v.x * v.x + v.y * v.y
end
func main():
v := Vec2{x = 3.0, y = 4.0}
norm := v.scale(2.0).squared_norm() // 100
end
Propagate failures from calls without results
In a throws func, try can now propagate a throwing call that does not return a value. If the call fails, the enclosing function returns through its error path; otherwise execution continues normally.
throws func save_record(record):
try write_record(record)
println("saved")
endNew library helpers and module fixes
The standard library now includes path::normalize for lexical path normalization and string::compare for lexicographic string comparison. The release also fixes module-import aliases, so importing the same file under different aliases consistently refers to the same module symbols and types.
