O Language: Database Management (and Object Relation Mapper)

O Language, you can write data directly into its own or SQL-based databases. With object-oriented data management, you can easily extract and manipulate your data. I will describe these database features in O Language in detail and with documentation using examples. This will tell you the features and how simple it is to make database management on O Language. This will save you extra time lost.

O Language: First Router

The router socket structure was created with the intention of creating an API over the HTTP/S protocol and exchanging data through the socket. In web based projects it is possible to write web server quickly and easily. In addition, the API can be created in micro-services.

hello.olm (as hello module):

def hello = fn(name){
 return "Hello, "+name+"! Welcome to Olang"

router.ola (as router script):

load "hello.olm"

def config = {
 "GET" : {
 "/" : "Welcome to the O-Lang Router!"
 "/:name" : hello("{{.name}}")

show("Listening Ctrl+C to exit.")
router("8080", config);

GET method test:

~> curl -X GET localhost:8080
Welcome to the O-Lang Router!

POST method test (oytun as parameter value for name [ :name => {{.name}} ]):

~> curl -X POST localhost:8080/oytun
Hello, oytun! Welcome to Olang

As you can see in the example, we wrote a web micro service using port 8080 via get and post methods.

O Language: HTTP Example Socket

The HTTP socket allows the HTTP protocol to be displayed on the web using any port. You can use the http(path, port, response) function to easily create an http socket.


def hello = fn(name){
 return "Hello, "+name+"! Welcome to Olang"


load "hello.olm"
show("Listening Ctrl+C to exit.")
http("/", "8080", hello("Oytun"));

First we loaded our “hello” module with load. Later in the hello() function on the 8080 port to provide this output. When we enter port localhost:8080 from our browser or curl, the result will be;

~> curl localhost:8080
 Hello, Oytun! Welcome to Olang

Now we can display the socket by connecting to 8080 port via HTTP. In the following lessons we will learn how to create routers and render pages on them.

O Language: Functions and Literals

The only difference between functions and literatures is that one of the brackets can be operated without parentheses. In this way you can define your own definitions.


The system has function definition function. These functions can be used many times.

def main = fn(param){
    return param

# => main function result:"Hello!"


You benefit by creating static functions directly in the system literature.

literal example(param){

main "Hello!"
# => main literal result:"Hello!"

Now we can begin to learn scope definitions.

O Language: Getting Started (Part 1)

System Oriented Functional Programming Language (SOFPL)

SOFPL is a specific structure that interprets each line separately and outputs the result. Shorten the functions performed in normal programming languages. For example, you can do the functions you can do in 10 lines with a line. It is up to you to determine what you will do in 9 lines. 🙂

In addition, you can start the process on the system, you can open the port and start data transfer. Simple socket software and transaction management functions are available and developed.
