Standalone Functions

It's common to use functions or methods that have no logical connection as members of classes. Dynamic languages with first-class functions such as JavaScript and Python typically declare these as standalone functions declare stored as regular variables. Static languages with class-based files such as C# and Java typically declare these as static methods within static classes.

Declaring Standalone Functions

Budgie unifies the two with the concept of a standalone function. These functions, similar to static functions, are referenced in Budgie code as members of some standalone container, which becomes a static class in static languages but goes away in dynamic languages.

Declaring a standalone function requires placing it within a group of them, similar to a static class declaration.

  • standalone functions declare start takes a single parameter as the name of the group in PascalCase, which will become the class name in static languages.

    It may take in the export keyword before the name of the group to indicate the group being available to import in other files.

  • standalone functions declare end closes the group and takes no parameters.

  • standalone function declare start takes in either public or private to indicate its availability outside of the group, the function name in PascalCase, return type, and any number of (name, type) pairs of parameters.

  • standalone function declare end closes a function and takes no parameters.

Calling standalone functions with standalone function takes in the name of the group in PascalCase, the privacy of the command, the name of the method in PascalCase, then any parameters.

standalone functions declare start : export TextUtilities
standalone function declare start : public SquareText string text string
return : { standalone function : private TextUtilities RepeatText text { string length : text } }
standalone function declare end
standalone function declare start : private RepeatText string text string times int
variable : combined string ""
for numbers start : i int 0 times
operation : combined (increase by) text
for numbers end
return : combined
standalone function declare end
standalone functions declare end

In C#:

public static class TextUtilities
public static string SquareText(string text)
return TextUtilities.RepeatText(text, text.Length);
private static string RepeatText(string text, int times)
string combined = "";
for (int i = 0; i < times; i++)
combined += text;
return combined;

In Python:

def square_text(text):
return repeat_text(text, len(text))
def repeat_text(text, times):
combined = ""
for (i in range(0, times)):
combined += text
return combined

Importing Standalone Functions

The import standalone functions command must be used after the use in import declarations. Different languages will import either the container group (static class) or individual functions. It takes in the name of the group in PascalCase followed by any number of standalone function names in PascalCase to import.

import local : Utilities Text use { import standalone functions : TextUtilities RepeatText }
variable : repeated string { standalone function : public TextUtilities RepeatText "foo" 7 }

In C#:

using Utilities.Text;
string repeated = TextUtilities.RepeatText("foo", 7);

In Python:

from "./utilities/text" import repeat_text
repeated = repeat_text("foo", 7)
