Keywords#
yükle#
imports or includes a module; or it can also bring items in to scope
Including#
you can think of including as copy-pasting the code in the module
py
yükle "my-module"* # notice the star
Importing#
importing is different however as it creates what we call named modules. you can use them under their names in this case. This is what we recommend you to use, especially when dealing with third-party modules. ```py yükle "my-module" -> my-module
imports "my-module" inside a variable called my-module#
```
Bringing Items into Scope#
py
yükle "math.trl" -> math # math.trl from tests/
yükle (math:factorial) # brings factorial from math into scope
4 factorial de
Stdout#
24
Note: while bringing things into scope; in case the language encounters identifier:
*, it will bring everything in identifier into the scope.

işlev#
functions in tr-lang
they are reusable bits of code that you can call.
They have their own stack and namespace.
They can return the last variable on the stack using the ver keyword.
```py
işlev recursive-sum-up-to -> a
a > 0 ise
a + (a --)recursive-sum-up-to ver
yoksa
0 ver

ver#
returns the last value in the stack from a function
Look above for an example in code
son#
ends an if-else, while, block(confusing isn't it?) or function block
=?instead
üst#
copy the variable second to last
py
10 5 üst -* same as 10 5 10 *-
tks#
swap the last variable on stack with the second last
py
32 64 tks -* same as 64 32 *-

py
"What's your name? " de girdi -* Terminal: What's your name? [some input from user] *-
"Your name is " de de ".\n" de -* Terminal: Your name is [some input from user]. *-
dön#
