WikiFlip

WikiFlip is a Flipper Zero FAP application that provides an offline cybersecurity dictionary. Version 1.3 uses static C data, so it builds without microSD parsing, external files, or network access at runtime.

English is the default language. Spanish is available from the in-app Settings menu.

Content

WikiFlip includes 100 terms in English and the same 100 terms in Spanish:

Architecture

WikiFlipApp
  Gui*
  ViewDispatcher*
  Submenu* categories_menu
  Submenu* terms_menu
  Submenu* settings_menu
  Widget* definition_widget
  FuriString* definition_buffer
  WikiFlipLanguage language
  WikiFlipCategory* current_category

The GUI uses ViewDispatcher with four views:

WikiFlipViewCategories   -> main category submenu
WikiFlipViewTerms        -> term submenu for selected category
WikiFlipViewSettings     -> language selector submenu
WikiFlipViewDefinition   -> scrollable definition widget

Long definitions are rendered with widget_add_text_scroll_element(). D-pad Up/Down provides native vertical scrolling.

Navigation

Open app
  -> Categories
      OK: open category terms
      Settings: open language selector
      Back: exit

  -> Settings
      OK: choose English or Spanish
      Back: return to categories

  -> Terms
      OK: open definition
      Back: return to categories

  -> Definition
      Up/Down: scroll
      Back: return to terms

Adding Terms

1. Open wikiflip.c.
2. Find the target category arrays for both languages:

static const WikiFlipTerm wikiflip_red_team_terms_en[] = {
    {
        .title = "C2",
        .definition = "Definition...",
    },
};

static const WikiFlipTerm wikiflip_red_team_terms_es[] = {
    {
        .title = "C2",
        .definition = "Definicion...",
    },
};

3. Add the matching entry to both arrays:

{
    .title = "New Term",
    .definition =
        "Long technical definition. Use \\n\\n for paragraph breaks "
        "and adjacent string literals to keep the source readable.",
},

WIKIFLIP_ARRAY_SIZE() calculates the term count at compile time.

Adding Categories

1. Create one array per language:

static const WikiFlipTerm wikiflip_forensics_terms_en[] = {
    {
        .title = "Timeline",
        .definition = "Chronological sequence of events used in forensic analysis.",
    },
};

2. Register the English category in wikiflip_categories_en[] and the Spanish category in wikiflip_categories_es[]:

{
    .name = "Forensics",
    .terms = wikiflip_forensics_terms_en,
    .term_count = WIKIFLIP_ARRAY_SIZE(wikiflip_forensics_terms_en),
},

Building With uFBT

From the project root:

ufbt

Expected output:

dist/wikiflip.fap

Install and launch on a USB-connected Flipper:

ufbt launch

Building Inside Firmware

Copy the project into applications_user for official firmware, Momentum, or another FBT-compatible fork:

Copy-Item -Recurse "C:\Users\R0G3R\Documents\Tools\Flipper Zero\WikiFlip" "C:\path\firmware\applications_user\WikiFlip"

Build:

.\fbt.cmd build APPSRC=applications_user\WikiFlip

Launch:

.\fbt.cmd launch APPSRC=applications_user\WikiFlip

Build by App ID:

.\fbt.cmd fap_wikiflip

Icon

The FAP icon is:

images/wikiflip_10px.png

It is a 10x10 px, 1-bit PNG with a compact book silhouette and WF lettering.

Memory Lifecycle

Allocation:

malloc(WikiFlipApp)
furi_record_open(RECORD_GUI)
view_dispatcher_alloc()
submenu_alloc()
submenu_alloc(settings_menu)
widget_alloc()
furi_string_alloc()
view_dispatcher_add_view()
view_dispatcher_attach_to_gui()

Free:

view_dispatcher_remove_view()
widget_free()
submenu_free(settings_menu)
submenu_free()
view_dispatcher_free()
furi_string_free()
furi_record_close(RECORD_GUI)
free(WikiFlipApp)

This order prevents the dispatcher from retaining references to already-freed views.
