Trash

Trash is simple and extensible programming language. It is something between Haskell, Tcl and Forth porgramming languages.

Example

Hello world:

$stdout "Hello, world!"

99 bottles of beer:

@while (([@int 99]) [@int 99] $stdout) {$1 gt 0} {
    $set (i stdout) ($1 $2)

    $set stdout [$stdout @i "bottles of beer on the wall,"]
    $set stdout [$stdout @i "bottles of beer!"]
    $set stdout [$stdout "Take one down, pass it around,"]
    $set stdout [$stdout [@i sub 1] "bottles of beer on the wall!"]

    (([@i sub 1]) [@i sub 1] $stdout)
}

You can find more examples in examples folder.

State

Now, trash interpreter is in alpha-testing version, all for core features and some base type methonds are implemented, but most of standart features (floating-point numbers, collections, functions, which generate sructures and enums, etc.) haven't been implemented yet.

Which featires are working now?

• $set operator (with multiple assignment)
• unquoted strings (may contain only ASCII alphanumeric symbols)
• quoted strings (without escape sequences)
• string variables (also quoted strings (without any escape characters))
• calling string variables and strings (any string returns itself)
• assigning closures to variables and calling them
• calling raw closures
• closures, which moves variables from scope to themself
• creating tuples, assigning and calling (any tuple returns itself) them
• len chars split push and eq methods for strings
• push pop len is_empty with without and {any number} methods for tuples
• integers, arithmetic operations with integers, chr method, @int cast function
• @if function, which calls condition closure and then call them closure or else closure
• @while function, which calls body closure, while condition closure returns true
• $stdout linear function, which prints its arguments to standart output
