-# 030-nato-phonetic-alphabet
+# 🚀 NATO phonetic alphabet
 
+A console tool that spells a word with the NATO phonetic alphabet and handles invalid input with exception handling, the Day 30 assignment of Udemy's "100 Days of Code: The Complete Python Pro Bootcamp". It is written for fellow course participants and GitHub visitors who want a readable, tested, runnable solution that has no runtime dependencies.

+
+## 🧭 Overview
+
+You type a word, the program prints the NATO code word of each letter. A character that is not a letter does not crash the program: the error is caught, you are told to enter letters only, and the program asks again.
+
+```text
+Enter a word: Hello
+Phonetic code words:
+Hotel
+Echo
+Lima
+Lima
+Oscar
+```
+
+How it works, in the course's terms:
+
+- `load_nato_dict` reads the supplied CSV file and builds the letter-to-code-word dictionary with a **dictionary comprehension**.
+- `spell_word` turns a word into its code words with a **list comprehension** inside a `try` block; a character that is not in the alphabet raises a `KeyError`, which the `except` block turns into an `InvalidWordError`.
+- `generate_phonetic` wraps the input and the error handling: it asks for a word, reports an invalid one and asks again until the word is valid.
+- The standard library `csv` module replaces Pandas, so the project has no runtime dependencies (see the architecture decision record [ADR-0001][ADR-0001]).
+
+The wiki explains installation, usage and development in English, Danish and Bahasa Malaysia: [wiki][wiki].
+
+## 📋 Requirements
+
+- Python 3.13 or newer, with the `venv` module.
+- Git, to clone the repository.
+- Optional: [Doxygen](https://www.doxygen.nl/) to build the source documentation.
+
+The program itself needs no packages. The development tools (pytest, ruff, mypy, import-linter) are installed by the `dev` extra.
+
+## 🛠️ Setup
+
+Clone the repository, then create a local virtual environment named `.venv` in its root, upgrade pip and install the project in editable mode with its development tools.
+
+### Windows PowerShell
+
+```powershell
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+py -3.13 -m venv .venv
+.\.venv\Scripts\Activate.ps1
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+If PowerShell refuses to run the activation script, allow it for this window only with `Set-ExecutionPolicy -Scope Process RemoteSigned`.
+
+### Linux Debian
+
+```bash
+sudo apt install git python3 python3-venv
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+Debian 13 (trixie) ships Python 3.13. On an older release install Python 3.13 first (for example with `pyenv`).
+
+### MacOS
+
+```bash
+brew install python@3.13 git
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3.13 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+## ▶️ Run
+
+With the virtual environment active:
+
+```bash
+python -m nato_phonetic_alphabet
+```
+
+or, as the installed command:
+
+```bash
+nato-phonetic-alphabet
+```
+
+An invalid character asks for the word again:
+
+![A word with a digit is rejected, then a valid word is spelled][screenshot-retry]
+
+## 🧪 Tests
+
+Run the tests with the virtual environment active:
+
+```bash
+python -m pytest
+```
+
+The same checks that CI runs:
+
+```bash
+python -m ruff check .
+python -m mypy
+lint-imports
+```
+
+## 🔄 Continuous integration
+
+The workflow [`.gitea/workflows/ci.yml`](.gitea/workflows/ci.yml) runs on every push to `main` or a `mil-*` branch and on every pull request that touches source, tests or configuration. It sets up Python 3.13, creates a virtual environment, installs the project with the `dev` extra, and runs ruff, mypy and pytest.
+
+## 📖 Build the source documentation
+
+The source is documented with Doxygen comments. From the repository root:
+
+```bash
+doxygen Doxyfile
+```
+
+Open `build/html/index.html` in a browser. The `build/` folder is ignored by git.
+
+## 🗂️ Project layout

+
+- Instance reviewed: [MIL-003]
+- Checklist used: [QC-MIL-001] and [QC-LANG-001]
+- Scope: full review
+- Language and domain: en / it
+- Language reviewer: none (the reviewer reads the language and knows the domain)
+- Mode: autonomous, not independent (the reviewer is `AI as stand-in for S01`)
+
+## Checklist Results
+
+| # | Criterion | Status | Evidence/Notes |
+| --- | --- | --- | --- |
+| 1 | A concrete deliverable is defined for every gate | Pass | Deliverable section names concrete output: README, screenshots and wiki in three languages. |
+| 2 | Explicit Go/No-Go criteria are stated for each gate | Pass | Go / No-Go table has objectively checkable rows (commands and counts). |
+| 3 | Dependencies on other milestones are explicitly mapped | Pass | Dependencies table is filled. |
+| 4 | Each milestone is traceable to a Business Case objective or KPI | Pass | Traceability cites [BC-001] objectives. |
+| 5 | Milestone owner and approving reviewer are identified | Pass | Owner and approving reviewer are S01. |
+| 6 | Milestone has a defined target date consistent with project constraints | Pass | Target date lies inside the Project Plan window; the Business Case sets no calendar constraint. |
+
+## Language and Domain Results
+
+| # | Criterion | Status | Evidence/Notes |
+| --- | --- | --- | --- |
+| 1 | The Metadata table has a `Language` row and a `Domain` row, and neither is a placeholder | Pass | `Language | en` and `Domain | it` are in the Metadata table. |
+| 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list | Pass | `en` is a BCP 47 code; `it` is in the registry's domain list. |
+| 3 | The content (prose and table cells) is written in the stated language | Pass | All prose and table cells are English; the course title is quoted source text. Checked by the stand-in reviewer, who reads English. |
+| 4 | The register matches the one the registry gives for the artifact type | Pass | The registry gives IT Executive English for this type; the text matches it. |
+| 5 | Domain terms are the PO terms of the domain's dictionary, with no synonyms | Pass | No dictionary (`DICT`) exists yet; the terms letter, code word and NATO alphabet are used consistently with no synonyms. Checked by the stand-in; open to challenge. |
+| 6 | Metadata keys, section headings, IDs and statuses are in English | Pass | Metadata keys, headings, IDs and statuses are English. |
+| 7 | No translated twin (`<name>.<language>.md`) exists beside the document | Pass | No translated twin of the file exists. |
+| 8 | A change of language or domain since the previous accepted version has a Version History row and was reviewed again | Pass | First version; no change of language or domain. |
+| 9 | A reviewer competent in the domain, and in the language, has confirmed that the domain terms are used correctly | Pass | The domain is software and IT and the language English; the reviewer stood in for (S01) reads both. A person may challenge this in the run summary. |
+| 10 | Abbreviations are spelled out on first use, in the stated language | Pass | Abbreviations are spelled out on first use or are identifiers (IDs, tool names). |
+
+## Overall Verdict
+
+Go — every Mandatory criterion of QC-MIL-001 and of QC-LANG-001 passes. The review is a stand-in review by the author's AI and is not independent; it is open to challenge in the run summary.

+## Coverage Notes
+
+- `-` in Upstream means foundational; in Downstream it means nothing is built on it yet; in Last Reviewed it means no review record exists.
+- PP-001 has no QC checklist yet; it is accepted by the Product Owner's stand-in.
+- WF-001 and PY-001 are labels for reviewed code instances (no artifact file).
+- PY-002 is the label of the reviewed converter code.

+Sæt projektet op først ([Installation](Install-da)). Udvidelsen `dev` installerer pytest, ruff, mypy og import-linter.
+
+## Kør testene
+
+```bash
+python -m pytest

+
+## Kør de kontroller, CI kører

+Åbn `build/html/index.html`. Installér Doxygen fra [doxygen.nl](https://www.doxygen.nl/) eller din pakkehåndtering.
+
+## Sådan virker exception handling
+
+`spell_word` (i `domain/spelling.py`) slår hvert bogstav op i ordbogen i en `try`-blok. Et tegn, der ikke findes i alfabetet, giver en `KeyError`, som `except`-blokken gør til en `InvalidWordError`. `generate_phonetic` (i `application/phonetic.py`) fanger fejlen, beder brugeren skrive kun bogstaver og spørger igen, indtil ordet er gyldigt.
+

+## Cara pengendalian pengecualian berfungsi
+
+`spell_word` (dalam `domain/spelling.py`) mencari setiap huruf dalam kamus di dalam blok `try`. Aksara yang tiada dalam abjad menimbulkan `KeyError`, yang ditukar oleh blok `except` kepada `InvalidWordError`. `generate_phonetic` (dalam `application/phonetic.py`) menangkap ralat itu, meminta pengguna memasukkan huruf sahaja dan bertanya semula sehingga perkataan itu sah.

+
+Set up the project first ([Install](Install)). The `dev` extra installs pytest, ruff, mypy and import-linter.
+
+## Run the tests
+
+```bash
+python -m pytest
+```
+
+## Run the checks that CI runs
+
+```bash
+python -m ruff check .
+python -m mypy
+lint-imports
+```
+
+## Build the source documentation
+
+```bash
+doxygen Doxyfile
+```
+
+Open `build/html/index.html`. Install Doxygen from [doxygen.nl](https://www.doxygen.nl/) or your package manager.
+
+## How the exception handling works
+
+`spell_word` (in `domain/spelling.py`) looks every letter up in the dictionary inside a `try` block. A character that is not in the alphabet raises a `KeyError`, which the `except` block turns into an `InvalidWordError`. `generate_phonetic` (in `application/phonetic.py`) catches that error, tells the user to enter letters only and asks again until the word is valid.
+
+## Code layout
+
+| Folder | Content |
+| --- | --- |
+| `src/nato_phonetic_alphabet/domain/` | The spelling rule, with no input or output |
+| `src/nato_phonetic_alphabet/application/` | The use case and its ports |
+| `src/nato_phonetic_alphabet/adapters/` | The CSV reader and the console |
+| `src/nato_phonetic_alphabet/constants.py` | Every literal of the program |
+| `tests/` | pytest tests, mirroring `src/` |
+
+Dependencies point inward: adapters know the application, the application knows the domain. import-linter enforces it.
+
+## Pull requests
+
+One branch and one pull request per milestone; CI must be green. The project follows the SQA and QC framework in `framework/`; see `docs/` for the plan and the review records.

+# NATO phonetic alphabet
+
+🌐 **English** · [Dansk](Home-da) · [Bahasa Melayu](Home-ms)
+
+A console tool that spells a word with the NATO phonetic alphabet. It is the Day 30 assignment of Udemy's "100 Days of Code: The Complete Python Pro Bootcamp" and shows exception handling: input that is not a letter is caught with `try` and `except` instead of crashing the program. It needs Python 3.13 or newer and has no runtime dependencies.

+# Installation
+
+🌐 [English](Install) · **Dansk** · [Bahasa Melayu](Install-ms)
+
+## Det skal du bruge
+
+- Python 3.13 eller nyere med modulet `venv`
+- Git
+
+## Trin
+
+Alle systemer gør de samme fire ting: klon repository'et, opret et virtuelt miljø kaldet `.venv`, opgradér pip og installér projektet.
+
+### Windows PowerShell
+
+```powershell
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+py -3.13 -m venv .venv
+.\.venv\Scripts\Activate.ps1
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+Hvis PowerShell afviser aktiveringsscriptet, så kør først `Set-ExecutionPolicy -Scope Process RemoteSigned`. Det gælder kun for det vindue.
+
+### Linux Debian
+
+```bash
+sudo apt install git python3 python3-venv
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+### macOS
+
+```bash
+brew install python@3.13 git
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3.13 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+## Tjek at det virker
+
+```bash
+python -m nato_phonetic_alphabet
+```
+
+Skriv et ord. Du skal se dets kodeord. Næste side: [Brug](Usage-da).

+# Pemasangan
+

+
+## Apa yang diperlukan
+
+- Python 3.13 atau lebih baharu dengan modul `venv`
+- Git
+
+## Langkah
+
+Semua sistem melakukan empat perkara yang sama: klon repositori, cipta persekitaran maya bernama `.venv`, naik taraf pip dan pasang projek.
+
+### Windows PowerShell
+
+```powershell
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+py -3.13 -m venv .venv
+.\.venv\Scripts\Activate.ps1
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+Jika PowerShell enggan menjalankan skrip pengaktifan, jalankan `Set-ExecutionPolicy -Scope Process RemoteSigned` dahulu. Ia hanya terpakai pada tetingkap itu.
+
+### Linux Debian
+
+```bash
+sudo apt install git python3 python3-venv
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+### macOS
+
+```bash
+brew install python@3.13 git
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3.13 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+## Semak ia berfungsi
+
+```bash
+python -m nato_phonetic_alphabet
+```
+
+Masukkan satu perkataan. Anda akan melihat kata kodnya. Seterusnya: [Penggunaan](Usage-ms).

+## What you need
+
+- Python 3.13 or newer with the `venv` module
+- Git
+
+## Steps
+
+Every system does the same four things: clone the repository, create a virtual environment called `.venv`, upgrade pip, install the project.
+
+### Windows PowerShell
+
+```powershell
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git

+py -3.13 -m venv .venv
+.\.venv\Scripts\Activate.ps1
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+If PowerShell refuses to run the activation script, run `Set-ExecutionPolicy -Scope Process RemoteSigned` first. It only applies to that window.
+
+### Linux Debian
+
+```bash
+sudo apt install git python3 python3-venv
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+### macOS
+
+```bash
+brew install python@3.13 git
+git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-nato-phonetic-alphabet.git
+cd 030-nato-phonetic-alphabet
+python3.13 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
