+
+## Description
+
+(Si vous voulez juste voir les derniers changements, vous pouvez regarder le [Changelog](changelog-fr.md) -- remarquez que le programme affiche le changelog si une version plus récente est détectée depuis la version 1.4.0.)
+
+Le fonctionnement du programme est assez simple : il converti une URL venant d'un site supporté en un fichier .epub pour les histoires ou .cbz pour les comics (d'autres options d'enregistrement sont disponibles, comme du texte simple, du HTML...)
+
+Pour vous aider à organiser vos histoires, il peut aussi servir de bibliothèque locale vous permettant :
+
+- d'importer une histoire depuis son URL (ou depuis un fichier)
+- d'exporter une histoire dans un des formats supportés vers un fichier
+- d'afficher une histoire en mode texte
+- via [fanfix-swing](https://github.com/nikiroo/fanfix-swing/): d'afficher une histoire en mode GUI **lui-même** ([fanfix-swing](https://github.com/nikiroo/fanfix-swing/)) ou **en appelant un programme natif pour lire le fichier** (potentiellement converti en HTML avant, pour que n'importe quel navigateur web puisse l'afficher)
+
+### Sites supportés
+
+Pour le moment, les sites suivants sont supportés :
+
+- http://FimFiction.net/ : fanfictions dévouées à la série My Little Pony
+- http://Fanfiction.net/ : fanfictions venant d'une multitude d'univers différents, depuis les shows télévisés aux livres en passant par les jeux-vidéos
+- http://mangahub.io/ : un site répertoriant une quantité non négligeable de mangas (English)
+- https://e621.net/ : un site Furry proposant des comics, y compris de MLP
+- https://sofurry.com/ : même chose, mais orienté sur les histoires plutôt que les images
+- https://e-hentai.org/ : support ajouté sur demande : n'hésitez pas à demander un site !
+- http://mangas-lecture-en-ligne.fr/ : un site proposant beaucoup de mangas, en français
+
+### Types de fichiers supportés
+
+Nous supportons les types de fichiers suivants (aussi bien en entrée qu'en sortie) :
+
+- epub : les fichiers .epub créés avec Fanfix (nous ne supportons pas les autres fichiers .epub, du moins pour le moment)
+- text : les histoires enregistrées en texte (.txt), avec quelques règles spécifiques :
+	- le titre doit être sur la première ligne
+	- l'auteur (précédé de rien, ```Par ```, ```De ``` ou ```©```) doit être sur la deuxième ligne, optionnellement suivi de la date de publication entre parenthèses (i.e., ```Par Quelqu'un (3 octobre 1998)```)
+	- les chapitres doivent être déclarés avec ```Chapitre x``` ou ```Chapitre x: NOM DU CHAPTITRE```, où ```x``` est le numéro du chapitre
+	- une description de l'histoire doit être donnée en tant que chaptire 0
+	- une image de couverture peut être présente avec le même nom de fichier que l'histoire, mais une extension .png, .jpeg ou .jpg
+- info_text : fort proche du format texte, mais avec un fichier .info accompagnant l'histoire pour y enregistrer quelques metadata (le fichier de metadata est supposé être créé par Fanfix, ou être compatible avec)
+- cbz : les fichiers .cbz (une collection d'images zipées), de préférence créés avec Fanfix (même si les autres .cbz sont aussi supportés, mais sans la majorité des metadata de Fanfix dans ce cas)
+- html : les fichiers HTML que vous pouvez ouvrir avec n'importe quel navigateur ; remarquez que Fanfix créera un répertoire pour y mettre les fichiers nécessaires, dont un fichier ```index.html``` pour afficher le tout -- nous ne supportons en entrée que les fichiers HTML créés par Fanfix
+
+### Plateformes supportées
+
+Toute plateforme supportant Java 1.6 devrait suffire.
+
+Le programme a été testé sur Linux (Debian, Slackware et Ubuntu), MacOS X et Windows pour le moment, mais n'hésitez pas à nous informer si vous l'essayez sur un autre système.
+
+Si vous avez des difficultés pour le compiler avec une version supportée de Java (1.6+), contactez-nous.
+
+## Options
+
+Vous pouvez démarrer le programme de deux façons :
+
+- ```java -jar fanfix.jar```
+- ```fanfix``` (si vous avez utilisé *make install*)
+
+Les arguments suivants sont supportés :
+
+- ```--import [URL]```: importer une histoire dans la librairie
+- ```--export [id] [output_type] [target]```: exporter l'histoire "id" vers le fichier donné
+- ```--convert [URL] [output_type] [target] (+info)```: convertir l'histoire vers le fichier donné, et forcer l'ajout d'un fichier .info si +info est utilisé
+- ```--read [id] ([chapter number])```: afficher l'histoire "id"
+- ```--read-url [URL] ([chapter number])```: convertir l'histoire et la lire à la volée, sans la sauver
+- ```--search```: liste les sites supportés (```where```)
+- ```--search [where] [keywords] (page [page]) (item [item])```: lance une recherche et affiche les résultats de la page ```page``` (page 1 par défaut), et de l'item ```item``` spécifique si demandé
+- ```--tag [where]```: liste tous les tags supportés par ce site web
+- ```--tag [index 1]... (page [page]) (item [item])```: affine la recherche, tag par tag, et affiche si besoin les sous-tags, les histoires ou les infos précises de l'histoire demandée
+- ```--list```: lister les histoires presentes dans la librairie et leurs IDs
+- ```--server [key] [port]```: démarrer un serveur d'histoires sur ce port
+- ```--stop-server [key] [port]```: arrêter le serveur distant sur ce port (key doit avoir la même valeur)
+- ```--remote [key] [host] [port]```: contacter ce server au lieu de la librairie habituelle (key doit avoir la même valeur)
+- ```--help```: afficher la liste des options disponibles
+- ```--version```: retourne la version du programme
+
+### Environnement
+
+Certaines variables d'environnement sont reconnues par le programme :
+
+- ```LANG=en```: forcer la langue du programme en anglais
+- ```CONFIG_DIR=$HOME/.fanfix```: utilise ce répertoire pour les fichiers de configuration du programme (et copie les fichiers de configuration par défaut si besoin)
+- ```NOUTF=1```: essaye d'utiliser des caractères non-unicode quand possible (cela peut avoir un impact sur les fichiers générés, pas uniquement sur les messages à l'utilisateur)
+- ```DEBUG=1```: force l'option ```DEBUG=true``` du fichier de configuration (pour afficher plus d'information en cas d'erreur)
+
+## Compilation
+
+```./configure.sh && make```
+
+Vous pouvez aussi importer les sources java dans, par exemple, [Eclipse](https://eclipse.org/), et faire un JAR exécutable depuis celui-ci.
+
+Quelques tests unitaires sont disponibles :
+
+```./configure.sh && make build test run-test```
+
+Si vous faites tourner les tests unitaires, sachez que certains fichiers flags peuvent les impacter:
+
+- ```test/VERBOSE```      : active le mode verbeux pour les erreurs
+- ```test/OFFLINE```      : ne permet pas au programme de télécharger des données
+- ```test/URLS```         : permet au programme de tester des URLs
+- ```test/FORCE_REFRESH```: force le nettoyage du cache
+
+Notez que le répertoire ```test/CACHE``` peut rester en place; il contient tous les fichiers téléchargés au moins une fois depuis le réseau par les tests unitaires (si vous autorisez les tests d'URLs, lancez les tests au moins une fois pour peupler le CACHE, puis activez le mode OFFLINE, ça marchera toujours).
+
+Les fichiers de test seront:
+
+- ```test/*.url```  : des URLs à télécharger en fichier texte (le contenu du fichier est l'URL)
+- ```test/*.story```: des histoires en mode texte (le contenu du fichier est l'histoire)
+
+### Librairies dépendantes (incluses)
+
+Nécessaires :
+
+- ```libs/nikiroo-utils-sources.jar```: quelques utilitaires partagés
+- [```libs/unbescape-sources.jar```](https://github.com/unbescape/unbescape): une librairie sympathique pour convertir du texte depuis/vers beaucoup de formats ; utilisée ici pour la partie HTML
+- [```libs/jsoup-sources.jar```](https://jsoup.org/): une libraririe pour parser du HTML
+- [```libs/JSON-java-20190722-sources.jar```](https://github.com/stleary/JSON-java): une libraririe pour parser du JSON
+
+Optionnelles :
+
+- [```libs/jexer-sources.jar```](https://github.com/klamonte/jexer): une petite librairie qui offre des widgets en mode TUI
+- [```pandoc```](http://pandoc.org/): pour générer les man pages depuis les fichiers README
+
+Rien d'autre, si ce n'est Java 1.6+.
+
+À noter : ```make libs``` exporte ces librairies dans le répertoire src/.

+# Fanfix
+
+Fanfix is a small Java program that can download stories from some supported websites and render them offline.
+
+## 🔴 This is the command line and server program
+
+You can also use:
+- the graphical client [Fanfix-swing](https://github.com/nikiroo/fanfix-swing/)
+- the TUI client [Fanfix-jexer](https://github.com/nikiroo/fanfix-jexer/)
+
+## Synopsis
+
+- ```fanfix``` --import [*URL*]
+- ```fanfix``` --export [*id*] [*output_type*] [*target*]
+- ```fanfix``` --convert [*URL*] [*output_type*] [*target*] (+info)
+- ```fanfix``` --read [*id*] ([*chapter number*])

+
+## Description
+
+(If you are interested in the recent changes, please check the [Changelog](changelog.md) -- note that starting from version 1.4.0, the changelog is checked at startup.)
+
+This program will convert from a (supported) URL to an .epub file for stories or a .cbz file for comics (a few other output types are also available, like Plain Text, LaTeX, HTML...).
+
+To help organize your stories, it can also work as a local library so you can:
+
+- Import a story from its URL (or just from a file)
+- Export a story to a file (in any of the supported output types)
+- Display a story from the local library in text format in the console
+- Via [fanfix-swing](https://github.com/nikiroo/fanfix-swing/): Display a story from the local library graphically **by itself** ([fanfix-swing](https://github.com/nikiroo/fanfix-swing/)) or **by calling a native program to handle it** (potentially converted into HTML before hand, so any browser can open it)
+
+### Supported websites
+
+Currently, the following websites are supported:
+
+- http://FimFiction.net/: fan fictions devoted to the My Little Pony show
+- http://Fanfiction.net/: fan fictions of many, many different universes, from TV shows to novels to games
+- http://mangahub.io/: a well filled repository of mangas (English)
+- https://e621.net/: a Furry website supporting comics, including MLP
+- https://sofurry.com/: same thing, but story-oriented
+- https://e-hentai.org/: done upon request (so, feel free to ask for more websites!)
+- http://mangas-lecture-en-ligne.fr/: a website offering a lot of mangas (in French)
+
+### Support file types
+
+We support a few file types for local story conversion (both as input and as output):
+
+- epub: .epub files created by this program (we do not support "all" .epub files, at least for now)
+- text: local stories encoded in plain text format, with a few specific rules:
+	- the title must be on the first line
+	- the author (preceded by nothing, ```by ``` or ```©```) must be on the second line, possibly with the publication date in parenthesis (i.e., ```By Unknown (3rd October 1998)```)
+	- chapters must be declared with ```Chapter x``` or ```Chapter x: NAME OF THE CHAPTER```, where ```x``` is the chapter number
+	- a description of the story must be given as chapter number 0
+	- a cover image may be present with the same filename as the story, but a .png, .jpeg or .jpg extension
+- info_text: contains the same information as the text format, but with a companion .info file to store some metadata (the .info file is supposed to be created by Fanfix or compatible with it)
+- cbz: .cbz (collection of images) files, preferably created with Fanfix (but any .cbz file is supported, though without most of Fanfix metadata, obviously)
+- html: HTML files that you can open with any browser; note that it will create a directory structure with ```index.html``` as the main file -- we only support importing HTML files created by Fanfix
+
+### Supported platforms
+
+Any platform with at lest Java 1.6 on it should be ok.
+
+It has been tested on Linux (Debian, Slackware, Ubuntu), MacOS X and Windows for now, but feel free to inform us if you try it on another system.
+
+If you have any problems to compile it with a supported Java version (1.6+), please contact us.
+
+## Options
+
+You can start the program in two ways:
+
+- ```java -jar fanfix.jar```
+- ```fanfix``` (if you used *make install*)
+
+The following arguments are allowed:
+
+- ```--import [URL]```: import the story at URL into the local library
+- ```--export [id] [output_type] [target]```: export the story denoted by ID to the target file
+- ```--convert [URL] [output_type] [target] (+info)```: convert the story at URL into target, and force-add the .info and cover if +info is passed
+- ```--read [id] ([chapter number])```: read the given story denoted by ID from the library
+- ```--read-url [URL] ([chapter number])```: convert on the fly and read the story at URL, without saving it
+- ```--search```: list the supported websites (```where```)
+- ```--search [where] [keywords] (page [page]) (item [item])```: search on the supported website and display the given results page of stories it found, or the story details if asked
+- ```--tag [where]```: list all the tags supported by this website
+- ```--tag [index 1]... (page [page]) (item [item])```: search for the given stories or subtags, tag by tag, and display information about a specific page of results or about a specific item if requested
+- ```--list```: list the stories present in the library and their associated IDs
+- ```--server [key] [port]```: start a story server on this port
+- ```--stop-server [key] [port]```: stop the remote server running on this port (key must be set to the same value)
+- ```--remote [key] [host] [port]```: contact this server instead of the usual library (key must be set to the same value)
+- ```--help```: display the available options
+- ```--version```: return the version of the program
+
+### Environment
+
+Some environment variables are recognized by the program:
+
+- ```LANG=en```: force the language to English
+- ```CONFIG_DIR=$HOME/.fanfix```: use the given directory as a config directory (and copy the default configuration if needed)
+- ```NOUTF=1```: try to fallback to non-unicode values when possible (can have an impact on the resulting files, not only on user messages)
+- ```DEBUG=1```: force the ```DEBUG=true``` option of the configuration file (to show more information on errors)
+
+## Compilation
+
+```./configure.sh && make```
+
+You can also import the java sources into, say, [Eclipse](https://eclipse.org/), and create a runnable JAR file from there.
+
+There are some unit tests you can run, too:
+
+```./configure.sh && make build test run-test```
+
+If you run the unit tests, note that some flag files can impact them:
+
+- ```test/VERBOSE```      : enable verbose mode
+- ```test/OFFLINE```      : to forbid any downloading
+- ```test/URLS```         : to allow testing URLs
+- ```test/FORCE_REFRESH```: to force a clear of the cache
+
+Note that ```test/CACHE``` can be kept, as it will contain all internet related files you need (if you allow URLs, run the test once which will populate the CACHE then go OFFLINE, it will still work).
+
+The test files will be:
+
+- ```test/*.url```  : URL to download in text format, content = URL
+- ```test/*.story```: text mode story, content = story
+
+
+### Dependant libraries (included)
+
+Required:
+
+- ```libs/nikiroo-utils-sources.jar```: some shared utility functions
+- [```libs/unbescape-sources.jar```](https://github.com/unbescape/unbescape): a nice library to escape/unescape a lot of text formats; used here for HTML
+- [```libs/jsoup-sources.jar```](https://jsoup.org/): a library to parse HTML
+- [```libs/JSON-java-20190722-sources.jar```](https://github.com/stleary/JSON-java): a library to parse JSON
+
+Optional:
+
+- [```libs/jexer-sources.jar```](https://github.com/klamonte/jexer): a small library that offers TUI widgets
+- [```pandoc```](http://pandoc.org/): to generate the man pages from the README files
+
+Nothing else but Java 1.6+.
+
+Note that calling ```make libs``` will export the libraries into the src/ directory.

+# Android UI mock-up
+
+## Concepts
+
+### Story
+
+We have **Stories** in Fanfix, which represent a story (an "epub", ...) or a comics (a "CBZ" file, ...).
+
+A story is written by an author, comes from a source and is dentified by a LUID (Local Unique ID).
+It can be a text story or an image story.
+
+The source can actually be changed by the user (this is the main sorting key).
+
+### Book
+
+We also have **Books**.
+
+Books can be used to display:
+
+- All the sources present in the library
+- All the authors known in the lbrary
+- Stories sharing a source or an author
+
+### All and Listing modes
+
+When representing sources or authors, books can be arranged in two modes:
+
+- "All" mode     : all the sources/authors are represented by a book and displayed in the UI
+- "Listing" mode : for each source/author, a group of books representing the corresponding story is present with the name of the source/author to group them (for instance, a JLabel on top of the group)
+
+Note: Listing mode can be left out of the Android version if needed (but the all mode is really needed).
+
+### Destination
+
+What I call here a destination is a specific group of books.
+
+Examples :
+
+- All the sources
+- All the books of author "Tulipe, F."
+- A listing of all the authors and their stories
+
+## Core
+
+### Library (main screen)
+
+![Main library](screens/main_lib.jpg)
+
+#### Header
+
+The header has a title, a navigation icon on the left and a search icon.
+
+Title can vary upon the current displayed books:
+
+- All sources
+- Sources listing
+- Source: xxx
+- All authors
+- Authors listing
+- Author: xxx
+
+The navigation icon open the Navigation drawer.
+
+##### Search
+
+![Search/Filter](screens/search.jpg)
+
+The search icon is actually a filter: it will hide all the books that don't contain the given text (search on LUID, title and author).
+
+#### List
+
+This list will hold books. Each item will be represented by :
+
+- a cover image (which is provided by fanfix.jar)
+- a main info, which can be:
+  - for stories, the story title
+  - for source books, the source name
+  - for author books, the author name
+- a secondary info, which can vary via a setting (see the Options page) between:
+  - author name (for a book representing an author, it is left blank)
+  - a count (a word count for text stories, an image count for images stories, a stories count for sources and authors books)
+
+#### UI
+
+Material.IO:
+
+- Title, navigation icon, search icon : [App bar top](https://material.io/design/components/app-bars-top.html)
+- List                                : [Cards](https://material.io/design/components/cards.html)
+
+A tap will open the target book in full-screen mode (i.e., the details about the card).
+
+On the detailed card, you will see the description (see Description Page) and 3 buttons :
+
+- Open
+- Delete
+- "..." for a menu
+
+### Navigation drawer
+
+![Navigation Drawer](screens/navigation.jpg)
+
+The navigation drawer will list 4 destinations:
+
+- All the sources
+- Listing of the sources
+- All the authors
+- Listing of the authors
+- By source
+
+...and 2 foldable "panels" with more destinations:
+
+- By source
+- By author
+
+Those subpanels will either contain the sources/authors **or** sub-subpanels with sources/authors.
+See fanfix.jar (BasicLibrary.getSourcesGrouped() and BasicLibrary.getAuthorsGrouped()).
+
+Note: if those last two cause problems, they can be removed; the first four options would be enough to cover the main use cases.
+
+#### UI
+
+Material.IO:
+
+- Navigation drawer: navigation drawer
+
+### Context menu
+
+![Context Menu](screens/menu.jpg)
+
+The context menu options are as follow for stories:
+
+- Open                : open the book (= internal or external reader)
+- Rename...           : ask the user for a new title for the story (default is current name)
+- Move to >>          : show a "new source..." option as well as the current ones fo quick select (BasicLibrary.getSourcesGrouped() will return all the sources on only one level if their number is small enough)
+  - *
+    - [new source...]
+  - [A-H]
+    - Anima
+    - Fanfiction.NET
+  - [I-Z]
+    - MangaFox
+- Change author to >> : show a "new author..." option as well as the current ones fo quick select (BasicLibrary.getAuthorsGrouped() will return all the authors on only one level if their number is small enough)
+  - *
+    - [new author...]
+  - [0-9]
+    - 5-stars
+  - [A-H]
+    - Albert
+    - Béatrice
+    - Hakan
+  - [I-Z]
+    - Irma
+    - Zoul
+- Delete              : delete the story
+- Redownload          : redownload the story (will **not** delete the original)
+- Properties          : open the properties page
+
+For other books (sources and authors):
+
+- Open: open the book (= go to the selected destination)
+
+#### UI
+
+Material.IO:
+
+- menu: [menu](https://developer.android.com/guide/topics/ui/menus.html)
+
+The menu will NOT use sublevels but link to a [list](https://material.io/design/components/lists.html) instead.
+
+### Description page
+
+![Description Page](screens/desc.jpg)
+
+#### Header
+
+Use the same cover image as the books, and the description key/values comes from BasicReader.getMetaDesc(MetaData).
+
+#### Description
+
+Simply display Story.getMeta().getResume(), without adding the chapter number (it is always 0 for description).
+
+An example can be seen in be.nikiroo.fanfix.ui.GuiReaderViewerTextOutput.java.
+
+### Options page
+
+![Options Page](screens/options.jpg)
+
+It consists of a "Remote Library" panel:
+
+- enable : an option to enable/disable the remote library (if disabled, use the local library instead)
+- server : (only enabled if the remote library is) the remote server host
+- port   : (only enabled if the remote library is) the remote server port
+- key    : (only enabled if the remote library is) the remote server secret key
+
+...and 5 other options:
+
+- Open CBZ files internally    : open CBZ files with the internal viewer
+- Open epub files internally   : open EPUB files with the internal viewer
+- Show handles on image viewer : can hide the handles used as cues in the image viewer to know where to click
+- Startup screen               : select the destination to show on application startup
+- Language                     : select the language to use
+
+#### Startup screen
+
+Can be:
+
+- Sources
+  - All
+  - Listing
+- Authors
+  - All
+  - Listing
+
+...but will have to be presented in a better way to the user (i.e., better names).
+
+#### UI
+
+Material.IO:
+
+- the page itself     : Temporary UI Region
+- the options         : Switch
+- the languages       : Exposed Dropdown Menu
+- the text fields     : the default for text fields
+- the scret key field : the default for passwords (with * * * )
+
+## Internal viewer
+
+The program will have an internal viewer that will be able to display the 2 kinds of stories (images and text).
+
+### Base viewer
+
+This is common to both of the viewer (this is **not** an architectural directives, I only speak about the concept here).
+
+![Base Viewer](screens/viewer.jpg)
+
+#### Header
+
+The title is the title of the story, shortened with "..." if too long.
+
+#### Content
+
+This area will host the text viewer or the image viewer.
+
+#### Navigator
+
+It contains 4 action buttons (first, previous, next and last chapter) and the title of the current chapter:
+
+- Descripton         : for the properties page (same layout as the actual Properties page)
+- Chapter X/Y: title : for the normal chapters (note that "Chapter X/Y" should be bold, and "X" should be coloured)
+
+#### UI
+
+Matrial.IO:
+
+- Header    : Header
+- Navigator : [Sheets bottom](https://material.io/design/components/sheets-bottom.html)
+
+### Text viewer
+
+![Text Viewer](screens/viewer-text.jpg)
+
+It will contain the content of the current chapter (Story.getChapters().get(index - 1)).
+
+Same layout as the Properties page uses for the resume, with just a small difference: the chapter name is now prefixed by "Chaper X: ".
+
+### Image viewer
+
+![Image Viewer](screens/viewer-image.jpg)
+
+#### Image
+
+Auto-zoom and fit (keep aspect ratio).
+
+#### Image counter
+
+Just display "Image X/Y"
+
+#### Handles
+
+This is a simple cue to show the user where to click.
+
+It can be hidden via the option "Show handles on image viewer" from the Options page.
+
+#### UI
+
+Pinch & Zoom should be allowed.
+
+Drag-to-pan should be allowed.

+Jexer - Java Text User Interface library
+========================================
+
+This library implements a text-based windowing system reminiscient of
+Borland's [Turbo Vision](http://en.wikipedia.org/wiki/Turbo_Vision)
+system.  (For those wishing to use the actual C++ Turbo Vision
+library, see [Sergio Sigala's C++ version based on the public domain
+sources released by Borland.](http://tvision.sourceforge.net/) )
+
+Jexer currently supports three backends:
+
+* System.in/out to a command-line ECMA-48 / ANSI X3.64 type terminal
+  (tested on Linux + xterm).  I/O is handled through terminal escape
+  sequences generated by the library itself: ncurses is not required
+  or linked to.  xterm mouse tracking using UTF8 and SGR coordinates
+  are supported.  For the demo application, this is the default
+  backend on non-Windows/non-Mac platforms.
+
+* The same command-line ECMA-48 / ANSI X3.64 type terminal as above,
+  but to any general InputStream/OutputStream or Reader/Writer.  See
+  the file jexer.demos.Demo2 for an example of running the demo over a
+  TCP socket.  jexer.demos.Demo3 demonstrates how one might use a
+  character encoding than the default UTF-8.
+
+* Java Swing UI.  This backend can be selected by setting
+  jexer.Swing=true.  The default window size for Swing is 80x25, which
+  is set in jexer.session.SwingSession.  For the demo application,
+  this is the default backend on Windows and Mac platforms.
+
+Additional backends can be created by subclassing
+jexer.backend.Backend and passing it into the TApplication
+constructor.
+
+The Jexer homepage, which includes additional information and binary
+release downloads, is at: https://jexer.sourceforge.io .  The Jexer
+source code is hosted at: https://github.com/klamonte/jexer .

+here](http://files.ax86.net/terminus-ttf/) .
+
+
+
+Usage
+-----
+
+Simply subclass TApplication and then run it in a new thread:
+
+```Java
+import jexer.*;
+
+class MyApplication extends TApplication {
+
+    public MyApplication() throws Exception {
+        super(BackendType.SWING); // Could also use BackendType.XTERM
+
+        // Create standard menus for File and Window
+        addFileMenu();
+        addWindowMenu();
+
+        // Add a custom window, see below for its code.
+        addWindow(new MyWindow(this));
+    }
+
+    public static void main(String [] args) {
+        try {
+            MyApplication app = new MyApplication();
+            (new Thread(app)).start();
+        } catch (Throwable t) {
+            t.printStackTrace();
+        }
+    }
+}
+```
+
+Similarly, subclass TWindow and add some widgets:
+
+```Java
+class MyWindow extends TWindow {
+
+    public MyWindow(TApplication application) {
+        // See TWindow's API for several constructors.  This one uses the
+        // application, title, width, and height.  Note that the window width
+        // and height include the borders.  The widgets inside the window
+        // will see (0, 0) as the top-left corner inside the borders,
+        // i.e. what the window would see as (1, 1).
+        super(application, "My Window", 30, 20);
+
+        // See TWidget's API for convenience methods to add various kinds of
+        // widgets.  Note that ANY widget can be a container for other
+        // widgets: TRadioGroup for example has TRadioButtons as child
+        // widgets.
+
+        // We will add a basic label, text entry field, and button.
+        addLabel("This is a label", 5, 3);
+        addField(5, 5, 20, false, "enter text here");
+        // For the button, we will pop up a message box if the user presses
+        // it.
+        addButton("Press &Me!", 5, 8, new TAction() {
+            public void DO() {
+                MyWindow.this.messageBox("Box Title", "You pressed me, yay!");
+            }
+        } );
+    }
+}
+```
+
+Put these into a file, compile it with jexer.jar in the classpath, run
+it and you'll see an application like this:
+
+![The Example Code Above](/screenshots/readme_application.png?raw=true "The application in the text of README.md")
+
+See the files in jexer.demos for many more detailed examples showing
+all of the existing UI controls.  The demo can be run in three
+different ways:
+
+  * 'java -jar jexer.jar' .  This will use System.in/out with
+    xterm-like sequences on non-Windows platforms.  On Windows it will
+    use a Swing JFrame.
+
+  * 'java -Djexer.Swing=true -jar jexer.jar' .  This will always use
+    Swing on any platform.
+
+  * 'java -cp jexer.jar jexer.demos.Demo2 PORT' (where PORT is a
+    number to run the TCP daemon on).  This will use the telnet
+    protocol to establish an 8-bit clean channel and be aware of
+    screen size changes.

+
+![Yo Dawg...](/screenshots/yodawg.png?raw=true "Yo Dawg, I heard you like text windowing systems, so I ran a text windowing system inside your text windowing system so you can have a terminal in your terminal.")
+
+
+
+System Properties
+-----------------
+
+The following properties control features of Jexer:
+
+  jexer.Swing
+  -----------
+
+  Used only by jexer.demos.Demo1.  If true, use the Swing interface
+  for the demo application.  Default: true on Windows platforms
+  (os.name starts with "Windows"), false on non-Windows platforms.
+
+  jexer.Swing.cursorStyle
+  -----------------------
+
+  Used by jexer.io.SwingScreen.  Selects the cursor style to draw.
+  Valid values are: underline, block, outline.  Default: underline.
+
+
+
+Known Issues / Arbitrary Decisions
+----------------------------------
+
+Some arbitrary design decisions had to be made when either the
+obviously expected behavior did not happen or when a specification was
+ambiguous.  This section describes such issues.
+
+  - See jexer.tterminal.ECMA48 for more specifics of terminal
+    emulation limitations.
+
+  - TTerminalWindow uses cmd.exe on Windows.  Output will not be seen
+    until enter is pressed, due to cmd.exe's use of line-oriented
+    input (see the ENABLE_LINE_INPUT flag for GetConsoleMode() and
+    SetConsoleMode()).
+
+  - TTerminalWindow launches 'script -fqe /dev/null' or 'script -q -F
+    /dev/null' on non-Windows platforms.  This is a workaround for the
+    C library behavior of checking for a tty: script launches $SHELL
+    in a pseudo-tty.  This works on Linux and Mac but might not on
+    other Posix-y platforms.
+
+  - Closing a TTerminalWindow without exiting the process inside it
+    may result in a zombie 'script' process.
+
+  - Java's InputStreamReader as used by the ECMA48 backend requires a
+    valid UTF-8 stream.  The default X10 encoding for mouse
+    coordinates outside (160,94) can corrupt that stream, at best
+    putting garbage keyboard events in the input queue but at worst
+    causing the backend reader thread to throw an Exception and exit
+    and make the entire UI unusable.  Mouse support therefore requires
+    a terminal that can deliver either UTF-8 coordinates (1005 mode)
+    or SGR coordinates (1006 mode).  Most modern terminals can do
+    this.
+
+  - jexer.session.TTYSession calls 'stty size' once every second to
+    check the current window size, performing the same function as
+    ioctl(TIOCGWINSZ) but without requiring a native library.
+
+  - jexer.io.ECMA48Terminal calls 'stty' to perform the equivalent of
+    cfmakeraw() when using System.in/out.  System.out is also
+    (blindly!)  put in 'stty sane cooked' mode when exiting.

+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+  processing mode) performed by means of including XHTML escape codes in literals.
+
+1.1.3.RELEASE
+=============
+- Improved performance of String-based unescape methods for HTML, XML, JS, JSON and others when the
+  text to be unescaped actually needs no unescaping.
+
+1.1.2.RELEASE
+=============
+- Added support for stream-based (String-to-Writer and Reader-to-Writer) escape and unescape operations.
+
+1.1.1.RELEASE
+=============
+- Fixed HTML unescape for codepoints > U+10FFFF (was throwing IllegalArgumentException).
+- Fixed HTML unescape for codepoints > Integer.MAX_VALUE (was throwing ArrayIndexOutOfBounds).
+- Simplified and improved performance of codepoint-computing code by using Character.codePointAt(...) instead
+  of a complex conditional structure based on Character.isHighSurrogate(...) and Character.isLowSurrogate(...).
+- [doc] Fixed description of MSExcel-compatible CSV files.
+
+
+1.1.0.RELEASE
+=============
+- Added URI/URL escape and unescape operations.

+# Fanfix
+
+## Screenshots
+
+Fanfix peut utiliser plusieurs interfaces :
+
+- GUI: une interface basée sur Swing, pour afficher le programme sur votre PC graphiquement
+- TUI: une interface basée sur [jexer](https://gitlab.com/klamonte/jexer/), pour afficher des fenêtre et des boutons en mode texte
+- CLI: une interface purement en lignes de commandes, facile à automatiser dans un script ou pour utiliser dans un terminal texte
+
+Cette gallerie reprend des screenshots de plusieurs versions de Fanfix, mais les versions les plus récentes sont affichées en premier.

+
+## Screenshots
+
+Fanfix can use different interfaces:
+

+ * <li>String</li>
+ * <li>Boolean</li>
+ * <li>Byte</li>
+ * <li>Character</li>

+     * A very fast and memory efficient class to encode and decode to and
+     * from BASE64 in full accordance with RFC 2045.<br><br> On Windows XP
+     * sp1 with 1.4.2_04 and later ;), this encoder and decoder is about 10
+     * times faster on small arrays (10 - 1000 bytes) and 2-3 times as fast
+     * on larger arrays (10000 - 1000000 bytes) compared to
+     * <code>sun.misc.Encoder()/Decoder()</code>.<br><br>
+     *
+     * On byte arrays the encoder is about 20% faster than Jakarta Commons
+     * Base64 Codec for encode and about 50% faster for decoding large
+     * arrays. This implementation is about twice as fast on very small
+     * arrays (&lt 30 bytes). If source/destination is a <code>String</code>
+     * this version is about three times as fast due to the fact that the
+     * Commons Codec result has to be recoded to a <code>String</code> from
+     * <code>byte[]</code>, which is very expensive.<br><br>
+     *
+     * This encode/decode algorithm doesn't create any temporary arrays as
+     * many other codecs do, it only allocates the resulting array. This
+     * produces less garbage and it is possible to handle arrays twice as
+     * large as algorithms that create a temporary array. (E.g. Jakarta
+     * Commons Codec). It is unknown whether Sun's
+     * <code>sun.misc.Encoder()/Decoder()</code> produce temporary arrays but
+     * since performance is quite low it probably does.<br><br>
+     *
+     * The encoder produces the same output as the Sun one except that the
+     * Sun's encoder appends a trailing line separator if the last character
+     * isn't a pad. Unclear why but it only adds to the length and is
+     * probably a side effect. Both are in conformance with RFC 2045
+     * though.<br> Commons codec seem to always att a trailing line
+     * separator.<br><br>
+     *
+     * <b>Note!</b> The encode/decode method pairs (types) come in three
+     * versions with the <b>exact</b> same algorithm and thus a lot of code
+     * redundancy. This is to not create any temporary arrays for transcoding
+     * to/from different format types. The methods not used can simply be
+     * commented out.<br><br>
+     *
+     * There is also a "fast" version of all decode methods that works the
+     * same way as the normal ones, but har a few demands on the decoded
+     * input. Normally though, these fast verions should be used if the
+     * source if the input is known and it hasn't bee tampered with.<br><br>
+     *
+     * If you find the code useful or you find a bug, please send me a note
+     * at base64 @ miginfocom . com.

+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and

+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The

+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.

+ *
+ * <p>
+ * - The vttest scenario for VT220 8-bit controls (11.1.2.3) reports a
+ *   failure with XTERM.  This is due to vttest failing to decode the UTF-8
+ *   stream.
+ *
+ * <p>
+ * - Smooth scrolling, printing, keyboard locking, keyboard leds, and tests
+ *   from VT100 are not supported.
+ *
+ * <p>
+ * - User-defined keys (DECUDK), downloadable fonts (DECDLD), and VT100/ANSI
+ *   compatibility mode (DECSCL) from VT220 are not supported.  (Also,
+ *   because DECSCL is not supported, it will fail the last part of the
+ *   vttest "Test of VT52 mode" if DeviceType is set to VT220.)
+ *
+ * <p>
+ * - Numeric/application keys from the number pad are not supported because
+ *   they are not exposed from the TKeypress API.
+ *
+ * <p>
+ * - VT52 HOLD SCREEN mode is not supported.
+ *
+ * <p>
+ * - In VT52 graphics mode, the 3/, 5/, and 7/ characters (fraction
+ *   numerators) are not rendered correctly.
+ *
+ * <p>
+ * - All data meant for the 'printer' (CSI Pc ? i) is discarded.
