 # Squirrel Battle
 
-Attention aux couteaux des écureuils !
+Squirrel Battle is an infinite rogue-like game with randomly generated levels, in which the player controls a squirrel in its quest down in a dungeon, using diverse items to defeat monsters, and trying not to die.
+
+## Installation
+
+#### Via PyPI :
+```
+$ pip install --user squirrel-battle
+```
+to install
+
+```
+$ pip install --user --upgrade squirrel-battle
+```
+to upgrade
+
+#### Via ArchLinux package :
+Download one of these two packages on the AUR :
+
+* python-squirrel-battle
+* python-squirrel-battle-git
+
+#### Via Debian package :
+Available on our git repository, has a dependency on fonts-noto-color-emoji (to be found in the official Debian repositories).
+
+Run
+```
+$ dpkg -i python3-squirrelbattle_23.14_all.deb
+```
+after downloading
+
+In all cases, execute via command line : `squirrel-battle`
+
+## For first-time players
+
+The game is played in a terminal only, preferably one that supports color, markdown and emojis, but it can be played with only grey levels and relatively classic unicode characters.
+
+Upon starting, the game will display the main menu. To navigate in menus, use zqsd or the keyboard arrows. To validate one of the options, use the Enter key. Mouse click is also supported in most menus, **but not in game**.
+
+The game in itself can have two types of display : using ascii and simple unicode characters, or using emojis. To activate emoji mode, go to the settings menu and select the squirrel texture pack. Emojis will not work if the terminal does not support them, so do tests before to ensure the terminal can display them.
+
+The game is translated (almost entirely) in English, French, German and Spanish. To change the language, go to the settings menu.
+
+Controls in-game are pretty basic : use zqsd or the keyboard arrows to move. To hit an ennemy, simply go in its direction if it is in an adjacent tile.
+
+There are several special control keys, they can be changed in the settings menu :
+
+* To close a store menu or go back to the main menu, use Space
+* To open/close the inventory, use i
+* To use an object in the inventory, use u
+* To equip an object in the inventory, use e
+* To use a long range weapon after it has been equipped, use l and then select the direction to shoot in
+* To drop an object from the inventory, use r (to pick up an object, simply go on its tile, its automatic)
+* To talk to certains entities (or open a chest), use t and then select the direction of the entity
+* To wait a turn (rather than moving), use w
+* To dance and confuse the ennemies, use y
+* To use a ladder, use <
+
+The dungeon consists in empty tiles (you can not go there), walls (which you can not cross) and floor ( :) ). Entities that move are usually monsters, but if you see a trumpet (or a '/'), do not kill it ! It is a familiar that will help you defeat monsters. Entities that do not move are either entities to which you can talk, like merchants and ... chests for some reason, or objects. Differentiating the two is not difficult, trying to go on the same tile as a living entity (or a chest) is impossible. Objects have pretty clear names, so it should not be too difficult determining what they do (if you still don't know, you can either read the docs, or test for yourself (beware of surprises though))
+
+And that is all you need to get started! You can now start your adventure and don't worry, floors are randomly generated, so it won't always be the same boring level.
 
 ## Documentation
 
-La documentation du projet est présente sur [squirrel-battle.readthedocs.io](https://squirrel-battle.readthedocs.io).

+
+Initialisation du terminal
+--------------------------
+
+Au lancement du jeu, le terminal est initialisé, les caractères spéciaux sont traduits en abstraction curses, les
+caractères tapés par l'utilisateur ne sont plus affichés sur le terminal, on envoie les touches tapées à curses en
+permanence sans avoir à taper sur Entrée, le curseur est rendu invisible, on active le support des couleurs et enfin
+on déclare vouloir attraper tous les clics de souris. Tout cela est fait dans un contexte Python, qui permet
+d'effectuer les opérations inverses lors de la fermeture du programme, même en cas de crash, afin de retrouver un
+terminal utilisable.
+
+
+Pads
+----
+
+Chaque morceau d'affichage est géré dans un *pad*. Un pad est un objet défini par curses, représentant une sous-fenêtre,
+qui a l'avantage d'être un peu plus flexible qu'une simple fenêtre. Un pad peut en effet dépasser de l'écran, et on
+peut choisir où placer le coin avant gauche et quelle partie du pad il faut dessiner sur la fenêtre.
+
+Ce projet implémente une couche d'abstraction supplémentaire, afin d'avoir des objets plus utilisables. Chaque partie
+d'affichage est réprésentée dans une classé étendant ``Display``. Chaque ``Display`` contient un (ou plusieurs) pads,
+et propose une surcouche de certaines fonctions de curses.
+
+L'affichage de texte par exemple sur un pad est plus sécurisée que celle proposée par curses. Le comportement par défaut
+est d'afficher un message à partir d'une position donnée avec des attributs (gras, couleur, ...) donnés sous
+forme numérique. Cette implémentation permet de passer les attributs voulus sous forme de paramètres booléens, de
+choisir la couleur de front/de fond sans définir de paire curses, mais surtout de tronquer le texte à la place
+disponible, afin de ne pas avoir à se soucier d'avoir un message trop grand et éviter des crashs non désirés.
+
+Les ``Display`` sont gérés par un ``DisplayManager``. C'est lui qui décide, en fonction de l'état actuel du jeu,
+d'afficher les bons ``Display`` aux bons endroits et de les redimensionner correctement en fonction de la taille du
+terminal. C'est aussi lui qui propage l'information de modifier les attributs d'un ``Display``, si par exemple
+l'inventaire du joueur a été mis à jour.
+
+Il s'occupe enfin de tout redimensionner si jamais le terminal a changé de taille, après une intervention
+de l'utilisateur.
+
+
+Interactions avec la souris
+---------------------------
+
+Le jeu attrape les clics de souris. C'est le ``DisplayManager``, connaissant l'état du jeu et ce qui est affiché à
+quel endroit, qui va chercher sur quel ``Display`` on a cliqué. L'information est propagée au bon ``Display``, en
+adaptant les coordonnées.
+
+Tout ``Display`` qui contient un menu procède de la même façon pour propager l'information au bon menu.

 Exécution des tests
 ===================
 
-.. note::
-  La documentation va être revue ici.
-
-Les tests sont gérés par ``pytest`` dans le module ``squirrelbattle.tests``.
-
 ``tox`` est un outil permettant de configurer l'exécution des tests. Ainsi, après
 installation de tox dans votre environnement virtuel via ``pip install tox``,
 il vous suffit d'exécuter ``tox -e py3`` pour lancer les tests et ``tox -e linters``
 pour vérifier la syntaxe du code.
+
+Tests unitaires
+---------------
+
+Les tests sont gérés par ``pytest`` dans le module ``squirrelbattle.tests``.
+Le module ``pytest-cov`` permet de mesurer la couverture du code.
+Pour lancer les tests, il suffit de lancer ``tox -e py3`` ou de manière équivalente
+``pytest --cov=squirrelbattle/ --cov-report=term-missing squirrelbattle/``
+
+L'intégration continue lance les tests pour les versions de Python de 3.6 à 3.10,
+sur une distribution Alpine Linux.
+
+Chaque partie du code est testée unitairement, pour obtenir une couverture
+maximale et assurer un bon fonctionnement. En particulier, le jeu est lancé
+en commençant sur une carte déterministe (non générée aléatoirement) chargée
+depuis ``assets/example_map.txt``, sur laquelle sont placés des ennemis et objets
+avec lesquels le joueur doit interagir. On vérifie qu'à chaque touche appuyée,
+il se passe le bon comportement. Le comportement des différents menus est
+également testé.
+
+L'environnement de test ne disposant pas a priori d'un terminal, le jeu est
+conçu pour fonctionner sans support graphique, avec un terminal fictif où les
+primitives de curses sont implémentées pour ne rien faire. On ne peut alors
+pas s'assurer du bon fonctionnement de curses.
+
+De plus, une très fine partie du code est ignorée lors de la couverture, ce
+qui correspond à la phase d'initialisation du terminal et à la boucle infinie
+qui reçoit les touches de l'utilisateur, qu'il est alors impossible de tester
+unitairement.
+
+
+Analyseur syntaxique
+--------------------
+
+``flake8`` est utilisé en guise d'analyseur syntaxique. Il vérifie si le code
+est bien formatté afin d'assurer une certaine lisibilité. En particulier,
+il vérifie l'indentation, si chaque variable est bien utilisée, s'il n'y a pas
+d'import inutile et s'ils sont dans l'ordre lexicographique, si chaque ligne
+fait au plus 80 caractères et si la signature de chaque fonction est bien
+spécifiée.
+
+Pour lancer l'analyse, ``tox -e linters`` suffit. L'intégration continue
+effectue cette analyse à chaque commit.

+Traduction
+==========
+
+Le jeu Squirrel Battle est entièrement traduit en anglais, en français et en allement.
+La langue se choisit dans les `paramètres <settings.html>`_.
+
+
+Utitisation
+-----------
+
+Les traductions sont gérées grâce au module natif ``gettext``. Le module
+``squirrelbattle.translations`` s'occupe d'installer les traductions, et de
+donner les chaînes traduites.
+
+Pour choisir la langue, il faut appeler ``Translator.setlocale(language: str)``,
+où ``language`` correspond au code à 2 lettres de la langue.
+
+Enfin, le module expose une fonction ``gettext(str) -> str`` qui permet de
+traduire les chaînes.
+
+Il est courant et recommandé d'importer cette fonction sous l'alias ``_``,
+afin de limiter la verbositer et de permettre de rendre facilement une chaîne
+traduisible.
+
+.. code:: python
+
+  from squirrelbattle.translations import gettext as _, Translator
+
+  Translator.setlocale("fr")
+  print(_("I am a translatable string"))
+  print("I am not translatable")
+
+Si les traductions sont bien faites (voir ci-dessous), cela donnera :
+
+.. code::
+
+  Je suis une chaîne traduisible
+  I am not translatable
+
+À noter que si la chaîne n'est pas traduite, alors par défaut on renvoie la
+chaîne elle-même.
+
+
+Extraction des chaînes à traduire
+---------------------------------
+
+L'appel à ``gettext`` ne fait pas que traduire les chaînes : il est possible
+également d'extraire toutes les chaînes à traduire.
+
+Il est nécessaire d'installer le paquet Linux ``gettext`` pour cela.
+
+L'utilitaire ``xgettext`` s'occupe de cette extraction. Il s'utilise de la façon
+suivante :
+
+.. code:: bash
+
+  xgettext --from-code utf-8 -o output_file.po source_1.py ... source_n.py
+
+Afin de ne pas avoir à sélectionner manuellement chaque fichier, il est possible
+d'appeler directement ``python3 main.py --makemessages``. Cela a pour effet
+d'exécuter pour chaque langue ``<LANG>`` :
+
+.. code:: bash
+
+  find squirrelbattle -iname '*.py' | xargs xgettext --from-code utf-8
+                    --add-comments
+                    --package-name=squirrelbattle
+                    --package-version=23.14
+                    "--copyright-holder=ÿnérant, eichhornchen, nicomarg, charlse"
+                    --msgid-bugs-address=squirrel-battle@crans.org
+                    -o squirrelbattle/locale/<LANG>/LC_MESSAGES/squirrelbattle.po
+
+Les fichiers de traductions se trouvent alors dans
+``squirrelbattle/locale/<LANG>/LC_MESSAGES/squirrelbattle.po``.
+
+
+Traduire les chaînes
+--------------------
+
+Après extraction des chaînes, les chaînes à traduire se trouvent dans
+``squirrelbattle/locale/<LANG>/LC_MESSAGES/squirrelbattle.po``, comme indiqué
+ci-dessus.
+
+Ce fichier peut-être édité avec un utilitaire tel que ``poedit``, sur
+l'interface Web sur `<https://translate.ynerant.fr/squirrel-battle/squirrel-battle>`_,
+mais surtout manuellement avec un éditeur de texte.
+
+Dans ce fichier, on obtient pour chaque chaîne à traduire un paragraphe de la
+forme :
+
+.. code:: po
+
+  #: main.py:4
+  msgid "I am a translatable string"
+  msgstr "Je suis une chaîne traduisible"
+
+Il sufift de remplir les champs ``msgstr``.
+
+
+Compilation des chaînes
+-----------------------
+
+Pour gagner en efficacité, les chaînes sont compilées dans un fichier avec
+l'extension ``.mo``. Ce sont ces fichiers qui sont lus par le module de traduction.
+
+Pour compiler les traductions, c'est l'utilitaire ``msgfmt`` fourni toujours par
+le paquet Linux ``gettext`` que nous utilisons. Il s'utilise assez simplement :
+
+.. code:: bash
+
+  msgfmt po_file.po -o mo_file.mo
+
+À nouveau, il est possible de compiler automatiquement les messages en exécutant
+``python3 main.py --compilemessages``.
+
+.. warning::
+
+  On ne partagera pas dans le dépôt Git les fichiers compilé. En développement,
+  on compilera soi-même les messages, et en production, la construction des
+  paquets se charge de compiler automatiquement les traductions.
