Curl is an open-source programming language built on Python technology

Curl Programming Language

Curl is an open-source programming language built on Python technology, designed to be simple and expressive. Every statement uses a keyword{...}\ style, and blocks are opened with - and closed with --\.

Why Curl?

Most programming languages treat AI as an afterthought — a third-party library you install, a client you configure, boilerplate you copy from a docs page. By the time you write response.choices[0].message.content, you've already forgotten what you were building.

Curl does it differently. pcAI is part of the language itself, the same way print is part of Python. There is no setup, no import, no client object. From the very first line of your program, you can ask a question and get an answer:

pcAI.ask{"What should I name this variable?"}\

That's the entire program. Not a demo — that actually runs.

This is what makes Curl different from every other language: AI is native syntax, not a library. You don't bolt it on at the end. You design around it from the start. Want a bot that remembers what you said three messages ago? It already does. Want to give it a personality? One line. Want to drop into a full interactive chat from inside a script? One line. Want to run it against your own local model with no API key at all? Point one environment variable at Ollama and you're done.

Curl is for people who want to build AI-powered programs without wading through infrastructure. For students writing their first script. For developers who want to prototype an idea in ten minutes instead of an afternoon. For anyone who's ever thought I just want to ask the computer a question and had to install four packages first.

Other languages got AI added to them. Curl was designed with it at the center.

Syntax Reference

Print — pcType

Outputs text to the console. Supports string concatenation with +.

pcType{"Hello, World!"}\
pcType{"Hello, " + var{name} + "!"}\

---

Input — pcAsk

Prompts the user for input. The result is accessed anywhere with input{ans}.

pcAsk{"What is your name? >>"}\
pcType{"You said: " + input{ans}}\

---

Variables — var

Assign a value with var{name, value}\. Reference it later with var{name}.

var{name, "Ritvik"}\
pcType{var{name}}\

Variables can hold strings, numbers, or lists.

---

Lists — list

Create a list with items separated by ;. Typically assigned to a variable.

var{colors, list{"red"; "green"; "blue"}}\
pcType{var{colors}}\

---

Functions — createFunc / func

Define a function with createFunc{name}- and close it with --\. Call it with func{name}\.

createFunc{greet}-
    pcType{"Hello from greet!"}\
--\

func{greet}\

---

Conditionals — if / elif / else

Simple if:

if{var{score} >= 90, then}-
    pcType{"Grade: A"}\
--\

If / else:

if{var{score} >= 90, then}-
    pcType{"Grade: A"}\
else:
    pcType{"Grade: B or below"}\
--\

If / elif / else:

if{var{score} >= 90, then}-
    pcType{"Grade: A"}\
elif{var{score} >= 80, then}-
    pcType{"Grade: B"}\
else:
    pcType{"Grade: C or below"}\
--\

For if+elif chains without an else, close with --\--\.

Supported comparison operators: == != < > <= >=

---

Embedded code blocks — otherCoding

Run a block of code written in another language. The closing }\ must be on its own line.

otherCoding{"Python",

x = 10
print("x =", x)

}\

Supported languages:

Language	Status
Python	Fully supported
JavaScript / Node.js	Supported (requires Node.js)
Java, C, C++	Not supported at runtime

---

Import — import

Import a Python package and give it a nickname.

import{"math", m}\

---

AI — pcAI + Curl-Bot

pcAI is a built-in AI module — no import required. It comes pre-connected to Curl-Bot, a fine-tuned model that knows everything about Curl syntax and has Curl-Bot's personality baked in.

Setup — get a free Hugging Face token at huggingface.co/settings/tokens, then:

export CURL_AI_KEY=hf_your_token_here

That's all. pcAI defaults to Curl-Bot automatically.

Ask a question:

var{reply, pcAI.ask{"What is the capital of France?"}}\
pcType{var{reply}}\

Interactive chat loop (type exit to quit):

pcAI.chat{""}\

Set a custom persona:

pcAI.context{"You are a friendly pirate who answers in rhymes."}\
var{reply, pcAI.ask{"What is 2 + 2?"}}\
pcType{var{reply}}\

Other methods:

var{s, pcAI.summarize{"some long text"}}\
var{a, pcAI.analyze{"some data"}}\
var{mood, pcAI.sentiment{"I love this!"}}\
var{t, pcAI.translate{"Bonjour — translate to English"}}\
pcAI.reset{""}\

Conversation history is kept across pcAI.ask calls and auto-compacts when it gets long.

Want to use a different model? Override with env vars:

Variable	Default	Description
CURL_AI_KEY	(required)	HF token, OpenAI key, etc.
CURL_AI_BASE_URL	https://api-inference.huggingface.co/v1	API base URL
CURL_AI_MODEL	gautamritvik/Curl-Bot	Model name

Works with Curl-Bot, OpenAI, OpenRouter, Ollama, or any OpenAI-compatible API.
