O Language/Web Framework

O Language Web Framework (olf)

olf is the convention-based web framework for O Language. It provides a project layout for routes, controllers, templates, browser assets, and database code.

Create and run a project

olang web init my-project
cd my-project
olang web run

The official framework source is the olf repository.

Project structure

Path	Responsibility
boot.ola	Starts the application by loading lib/loader.olm.
lib/loader.olm	Central loader for every generated and installed module.
config/config.ola	HTTP route table.
controllers/	Request handler functions.
models/	Data model definitions.
connections/	Database connection definitions.
templates/	Server-rendered HTML templates.
public/	Browser assets.
library.olp	Project metadata and dependencies.
proc.ops	Local process definition.

Generate application components

olang web create controller home
olang web create model user
olang web create connection main
olang web create route get /users/:id show_user

The web CLI updates lib/loader.olm whenever it creates or installs a component. Controller and route definitions are written to config/config.ola; no separate route file is created. Generated controller functions are intentionally empty so the developer can fill in the behavior.

Add libraries

olang web add <remote> <library-name>
olang web install
olang web update

The dependency is recorded in library.olp, installed under lib/, and its entry point is added to the central loader.

Templates and request data

def main = fn() {
  return renderf("templates/index.html", {
    "title": "My Olang App",
    "body": "Welcome!"
  })
}

Use server.parameters for route parameters and server.get, server.post, server.headers, and server.form for request data.
