I built a programming language that speaks Urdu, Turkish, and Spanish — from an Android phone

English is the invisible gatekeeper of programming. Before you write your first if, you already need to read English. For 6 billion people, that's not a feature — it's a wall.

Two years ago I started asking a simple question: what if programming keywords existed natively in the learner's mother tongue?

The answer became NexusLang — an open-source, self-contained programming language where you write agar instead of if in Urdu, eğer in Turkish, si in Spanish. The compiler bridges it to standard English syntax under the hood, so you think in your language but ship in the world's language.

Today, three language packs are live (Urdu, Turkish, Spanish) plus English. 25 native keywords each. 100% test suite passing. Built solo from an Android phone in Argentina, with zero budget and a cross-border partnership in Pakistan.

Here's what I learned.

Why this matters

Most "inclusive" programming projects focus on UX. They make the editor prettier, the errors friendlier. But none of them touch the actual syntax. You still write function, return, while in English.

NexusLang attacks the gate itself.

The insight is simple: keywords are vocabulary, not grammar. The grammar of programming — scope, types, control flow — is universal. The vocabulary is just labels. And labels can be translated.

How the bridge works (v11 architecture)

NexusLang v11 is self-contained. It does NOT translate to Python. Source code runs on its own engine:

Lexer — tokenizes source (Urdu/Spanish/English keywords), respecting strings and comments.
Parser — recursive descent, builds an AST.
Interpreter — tree-walk execution over the AST with scoped environments.

Under the hood, each native keyword maps to its English equivalent during tokens:
compiles to:
The AST is identical. The compiled output is valid standard code. No magic, no runtime overhead, no lock-in.

A learner can start in their mother tongue, get fluent, and gradually switch to English keywords without rewriting a single line.

Real syntax, real semantics

NexusLang isn't a toy. It ships with:

Imperative: variables, operators, conditionals, loops (while, for, break, continue)
Functions: recursion, closures
Data: lists [.] with indexing a[0], dicts, strings, math
OOP: classes (کلاس), self (خود), constructor (بنا), methods, attributes
Modules: برآمد("file.nx")
File I/O: read / write
Errors: try/catch (کوشش/پکڑ) + friendly messages in the learner's language
REPL: interactive shell
Trilingual keywords: Urdu / Spanish / English

Three language packs, 25 keywords each

The current packs cover the most-spoken languages that also have the largest populations excluded from English-first tech education — with a deliberate focus on Pakistan, where Urdu is the national language and English proficiency is a real barrier to entry:

Urdu (پاکستان) — agar, warna, jabtak, chapo, کلاس, خود, بنا
Turkish (Türkiye) — eğer, yoksa, sürece, yazdır
Spanish (LatAm + España) — si, sino, mientras, imprimir
English (global baseline)

Each pack ships with a dedicated formatter (LAF) and its own test suite. Urdu has full RTL support in the web interface.

Built from an Android phone

I don't have a laptop. I built the entire stack — compiler, parser, test runner, web interface, documentation, marketplace — from Termux on a mid-range Android phone.

This is not a gimmick. It's a design constraint that forced elegance. Every decision had to be defensible on a 6-inch screen and a slow 4G connection. The codebase ended up smaller, cleaner, and more testable than it would have been with a full workstation.

The partnership with Pakistan is real: a co-founder in Lahore handles seller onboarding for NexusShop (the parallel marketplace), and we share equity 50/50. The language packs will pilot in Pakistani technical schools next quarter through the Virtual University of Pakistan.

Current status

Component	Status	Version
NexusLang Core	✅ Stable	v9.4
NexusVM	✅ Stable	v8
NexusBase (Ledger)	✅ Stable	v9
NexusShop	🚧 Pilot	v1
Urdu RTL Support	✅ Stable	v6

Roadmap

[ ] NexusShop pilot launch (Pakistan, Nigeria)
[ ] University pilot program (Virtual University of Pakistan)
[ ] Mobile app for merchant onboarding
[ ] Community-contributed keyword libraries (Hindi, Arabic, Portuguese)
[ ] NexusLang Pro (advanced features for professionals)

What's next

Pakistani school pilots: NexusLang as the first language in 3 technical institutes
5th language pack: Arabic (RTL support in the web interface)
IDE integrations: VSCode extension with native keyword autocomplete
Bridge to WebAssembly: so NexusLang code runs anywhere JavaScript runs

The question I'm sitting with

Is a mother-tongue programming language a real contribution to CS, or is it a pedagogical bridge that learners outgrow in 6 months?

I don't know yet. But I know that every learner who writes their first agar in Urdu instead of staring blankly at if is a small win against the gatekeeper.
