nudoku is a ncurses based sudoku game.

nudoku is easily installable via many package managers.

• ncurses
• cairo (optional: for PDF/PNG output)

Get the latest .tar.xz release and extract it. Then run:

./configure
make
./src/nudoku

For the git version you will have to do:

git clone https://github.com/jubalh/nudoku
cd nudoku
autoreconf -i
./configure
make
./src/nudoku

Add -DDEBUG to make to have some debug output.

nudoku can also output sudokus in PDF and PNG format (see man nudoku -p/-i/-n). You need to have cairo installed and configure with:

./configure --enable-cairo

For normal interactive GUI run nudoku. To print two PDF pages with 8 hard sudokus run nudoku -p riddle.pdf -n 8 -d hard. To get a PNG with an easy sudoku run nudoku -i sudoku.png -d easy. See man nudoku to learn more.

For i18n support you need to set LANGUAGE variable:

export LANGUAGE=lang

Where lang is the translation of choice. See the list of supported languages in po/LINGUAS file.

If you plan to add/update the translation please follow these guidelines with examples:

1. Fork this repository and create a new git branch with language abbreviation as a name, e.g. es:

cd nudoku # your forked git repository
git checkout -b es

2. For new translation add language to po/LINGUAS and create .po file:

echo es >> po/LINGUAS && cp po/nudoku.pot po/es.po

3. Replace placeholders in uppercase in the head of the file with your information. Add translations for (preferably) each msgid.
4. Check your .po file with msgfmt for any errors:

msgfmt es.po # should not produce any output

5. Push your branch to remote and create PR:

git push origin es

If you add changes to source code make sure to update potfiles as well:

cd po # if you inside nudoku directory
make update-po
