f06e3a0a82 fix: align battery icon based on context (UI / Reader) (#796)
Issues solved: #729 and #739

## Summary

* **What is the goal of this PR?**
Currently, the battery icon and charge percentage were aligned to the
left even for the UI, where they were positioned on the right side of
the screen. This meant that when changing values of different numbers of
digits, the battery would shift, creating a block of icons and text that
was illegible.

* **What changes are included?**
- Add drawBatteryUi() method for right-aligned battery display in UI
headers
- Keep drawBattery() for left-aligned display in reader mode
- Extract drawBatteryIcon() helper to reduce code duplication
- Battery icon now stays fixed at right edge regardless of percentage
digits
- Text adjusts to left of icon in UI mode, to right of icon in reader
mode

## Additional Context

* Add any other information that might be helpful for the reviewer 
* This fix applies to both themes (Base and Lyra).

f1966f1e26 feat: User-Interface I18n System (#728)
**What is the goal of this PR?**
This PR introduces Internationalization (i18n) support, enabling users
to switch the UI language dynamically.

**What changes are included?**
- Core Logic: Added I18n class (`lib/I18n/I18n.h/cpp`) to manage
language state and string retrieval.

- Data Structures:

- `lib/I18n/I18nStrings.h/cpp`: Static string arrays for each supported
language.
  - `lib/I18n/I18nKeys.h`: Enum definitions for type-safe string access.
  - `lib/I18n/translations.csv`: single source of truth.

- Documentation: Added `docs/i18n.md` detailing the workflow for
developers and translators.

- New Settings activity:
`src/activities/settings/LanguageSelectActivity.h/cpp`

This implementation (building on concepts from #505) prioritizes
performance and memory efficiency.

The core approach is to store all localized strings for each language in
dedicated arrays and access them via enums. This provides O(1) access
with zero runtime overhead, and avoids the heap allocations, hashing,
and collision handling required by `std::map` or `std::unordered_map`.

The main trade-off is that enums and string arrays must remain perfectly
synchronized—any mismatch would result in incorrect strings being
displayed in the UI.

To eliminate this risk, I added a Python script that automatically
generates `I18nStrings.h/.cpp` and `I18nKeys.h` from a CSV file, which
will serve as the single source of truth for all translations. The full
design and workflow are documented in `docs/i18n.md`.

- [x] Python script `generate_i18n.py` to auto-generate C++ files from
CSV
- [x] Populate translations.csv with initial translations.

Currently available translations: English, Español, Français, Deutsch,
Čeština, Português (Brasil), Русский, Svenska.
Thanks, community!

**Status:** EDIT: ready to be merged.

As a proof of concept, the SPANISH strings currently mirror the English
ones, but are fully uppercased.

I used AI for the black work of replacing strings with I18n references
across the project, and for generating the documentation. EDIT: also
some help with merging changes from master.

ed8a0feac1 refactor: move render() to Activity super class, use freeRTOS notification (#774)
Currently, each activity has to manage their own `displayTaskLoop` which
adds redundant boilerplate code. The loop is a wait loop which is also
not the best practice, as the `updateRequested` boolean is not protected
by a mutex.

In this PR:
- Move `displayTaskLoop` to the super `Activity` class
- Replace `updateRequested` with freeRTOS's [direct to task
notification](https://www.freertos.org/Documentation/02-Kernel/02-Kernel-features/03-Direct-to-task-notifications/01-Task-notifications)
- For `ActivityWithSubactivity`, whenever a sub-activity is present, the
parent's `render()` automatically goes inactive

With this change, activities now only need to expose `render()`
function, and anywhere in the code base can call `requestUpdate()` to
request a new rendering pass.

In theory, this change may also make the battery life a bit better,
since one wait loop is removed. Although the equipment in my home lab
wasn't been able to verify it (the electric current is too noisy and
small). Would appreciate if anyone has any insights on this subject.

Update: I managed to hack [a small piece of
code](https://github.com/ngxson/crosspoint-reader/tree/xsn/measure_cpu_usage)
that allow tracking CPU idle time.

The CPU load does decrease a bit (1.47% down to 1.39%), which make
sense, because the display task is now sleeping most of the time unless
notified. This should translate to a slightly increase in battery life
in the long run.

b965ce9fb7 fix: Port upstream cover extraction fallback and outline improvements
Port PR #838 (epub cover fallback logic) and PR #907 (cover outlines):

- Add fallback cover filename probing when EPUB metadata lacks cover info
- Case-insensitive extension checking for cover images
- Detect and re-generate corrupt/empty thumbnail BMPs
- Always draw outline rect on cover tiles for legibility (PR #907)
- Upgrade Storage.exists() checks to Epub::isValidThumbnailBmp()
- Fallback chain: Real Cover → PlaceholderCoverGenerator → X-pattern marker
- Add epub.load retry logic (cache-only first, then full build)
- Adapt upstream Serial.printf calls to LOG_DBG/LOG_ERR macros

f90aebc891 fix: Defer low-power mode during section indexing and book loading
Prevent the device from dropping to 10MHz CPU during first-time chapter
indexing, cover prerendering, and other CPU-intensive reader operations.

Three issues addressed:
- ActivityWithSubactivity now delegates preventAutoSleep() and
  skipLoopDelay() to the active subactivity, so EpubReaderActivity's
  signal is visible through the ReaderActivity wrapper
- Added post-loop() re-check of preventAutoSleep() in main.cpp to
  catch activity transitions that happen mid-loop
- EpubReaderActivity uses both !section and a loadingSection flag to
  cover the full duration from activity entry through section file
  creation; TxtReaderActivity uses !initialized similarly

Also syncs HalPowerManager.cpp log messages with upstream PR #852.

632b76c9ed feat: Add placeholder cover generator for books without covers
Generate styled placeholder covers (title, author, book icon) when a
book has no embedded cover image, instead of showing a blank rectangle.

- Add PlaceholderCoverGenerator lib with 1-bit BMP rendering, scaled
  fonts, word-wrap, and a book icon bitmap
- Integrate as fallback in Epub/Xtc/Txt reader activities and
  SleepActivity after format-specific cover generation fails
- Add fallback in HomeActivity::loadRecentCovers() so the home screen
  also shows placeholder thumbnails when cache is cleared
- Add Txt::getThumbBmpPath() for TXT thumbnail support
- Add helper scripts for icon and layout preview generation

- Add onDone callback to DictionaryDefinitionActivity for direct
  exit-to-reader via "Done" button
- Refactor DictionaryWordSelectActivity to ActivityWithSubactivity
  with cascading lookup (exact → stems → suggestions → not found),
  en-dash/em-dash splitting, and cross-page hyphenation
- Refactor LookedUpWordsActivity with reverse-chronological order,
  inline cascading lookup, UITheme-aware rendering, and sub-activities
- Simplify EpubReaderActivity LOOKUP/LOOKED_UP_WORDS handlers

82bfbd8fa6 merge upstream/master: logging pragma, screenshot retrieval, nbsp fix
Merge 3 upstream commits into mod/master:
- feat: Allow screenshot retrieval from device (#820)
- feat: Add central logging pragma (#843)
- fix: Account for nbsp character as non-breaking space (#757)

Conflict resolution:
- src/main.cpp: kept mod's HalPowerManager + upstream's Logging/screenshot
- SleepActivity.cpp: kept mod's letterbox fill rework, applied LOG_* pattern

Additional changes for logging compatibility:
- Converted remaining Serial.printf calls in mod files to LOG_* macros
  (HalPowerManager, BookSettings, BookmarkStore, GfxRenderer)
- Added ENABLE_SERIAL_LOG and LOG_LEVEL=2 to [env:mod] build flags

6aa0b865c2 feat: Add per-book letterbox fill override
Introduce BookSettings utility for per-book settings stored in
the book's cache directory (book_settings.bin). Add "Letterbox Fill"
option to the EPUB reader menu that cycles Default/Dithered/Solid/None.
At sleep time, the per-book override is loaded and takes precedence
over the global setting for all book types (EPUB, XTC, TXT).

cb24947477 feat: Add central logging pragma (#843)
## Summary

* Definition and use of a central LOG function, that can later be
extended or completely be removed (for public use where debugging
information may not be required) to save flash by suppressing the
-DENABLE_SERIAL_LOG like in the slim branch

* **What changes are included?**

## Additional Context
* By using the central logger the usual:
```
#include <HardwareSerial.h>
...
  Serial.printf("[%lu] [WCS] Obfuscating/deobfuscating %zu bytes\n", millis(), data.size());
```
would then become
```
#include <Logging.h>
...
  LOG_DBG("WCS", "Obfuscating/deobfuscating %zu bytes", data.size());
```
You do have ``LOG_DBG`` for debug messages, ``LOG_ERR`` for error
messages and ``LOG_INF`` for informational messages. Depending on the
verbosity level defined (see below) soe of these message types will be
suppressed/not-compiled.

* The normal compilation (default) will create a firmware.elf file of
42.194.356 bytes, the same code via slim will create 42.024.048 bytes -
170.308 bytes less
* Firmware.bin : 6.469.984 bytes for default, 6.418.672 bytes for slim -
51.312 bytes less

21a75c624d feat: Implement bookmark functionality for epub reader
Replace bookmark stubs with full add/remove/navigate implementation:

- BookmarkStore: per-book binary persistence on SD card with v2 format
  supporting text snippets (backward-compatible with v1)
- Visual bookmark ribbon indicator drawn on bookmarked pages via fillPolygon
- Reader menu dynamically shows Add/Remove Bookmark based on current page state
- Bookmark selection activity with chapter name, first sentence snippet, and
  page number display; long-press to delete with confirmation
- Go to Bookmark falls back to Table of Contents when no bookmarks exist
- Smart snippet extraction: skips partial sentences (lowercase first word)
  to capture the first full sentence on the page
- Label truncation reserves space for page suffix so it's never cut off
- Half refresh forced on menu exit to clear popup/menu artifacts

7f40c3f477 feat: add HalStorage (#656)
## Summary

Continue my changes to introduce the HAL infrastructure from
https://github.com/crosspoint-reader/crosspoint-reader/pull/522

This PR touches quite a lot of files, but most of them are just name
changing. It should not have any impacts to the end behavior.

## Additional Context

My plan is to firstly add this small shim layer, which sounds useless at
first, but then I'll implement an emulated driver which can be helpful
for testing and for development.

Currently, on my fork, I'm using a FS driver that allow "mounting" a
local directory from my computer to the device, much like the `-v` mount
option on docker. This allows me to quickly reset `.crosspoint`
directory if anything goes wrong. I plan to upstream this feature when
this PR get merged.

e6f5fa43e6 feat(ux): invert BACK button behavior in reader activities (#726)
## Summary

* Inverts back button behaviour while reading - short press to go home,
long press to open file browser

## Additional Context

* It seems counterintuitive that going into a book from home screen and
pressing back doesn’t take you back to the home screen. With the recent
books now displayed in the home view and a separate recents view, going
directly to the file browser is less necessary.

c3b9bc38b9 feat: Add Chapter Progress Bar status bar option (#636)
## Summary
This pull request introduces a new "Chapter Progress Bar" mode to the
status bar, allowing users to track their progress within the current
chapter in addition to the existing book-level progress options. It also
unifies and increases the progress bar height for better visibility, and
updates the settings UI to support the new mode.

Closes #636

**Status Bar/Progress Bar Enhancements:**

* Added a new `CHAPTER_PROGRESS_BAR` mode to
`CrossPointSettings::STATUS_BAR_MODE`, and updated the settings UI to
allow users to select this mode.

fb0af32ec0 feat: Move Sync feature to menu (#680)
## Summary

* **What is the goal of this PR?** 
Move the "Sync Progress" option from TOC (Chapter Selection) screen to
the Reader Menu, and fix use-after-free crashes related to callback
handling in activity lifecycle.

* **What changes are included?**
- Added "Sync Progress" as a menu item in `EpubReaderMenuActivity` (now
4 items: Go to Chapter, Sync Progress, Go Home, Delete Book Cache)
- Removed sync-related logic from `EpubReaderChapterSelectionActivity` -
TOC now only displays chapters
- Implemented `pendingGoHome` and `pendingSubactivityExit` flags in
`EpubReaderActivity` to safely handle activity destruction
- Fixed GO_HOME, DELETE_CACHE, and SYNC menu actions to use deferred
callbacks avoiding use-after-free

## Additional Context

* Root cause of crashes: callbacks like `onGoHome()` or `onCancel()`
invoked from activity handlers could destroy the current activity while
code was still executing, causing use-after-free and race conditions
with FreeRTOS display task.
* Solution: Deferred execution pattern - set flags and process them in
`loop()` after all nested activity loops have safely returned.
* Files changed: `EpubReaderMenuActivity.h`,
`EpubReaderActivity.h/.cpp`, `EpubReaderChapterSelectionActivity.h/.cpp`

bf87a7dc60 feat: UI themes, Lyra (#528)
## Summary

### What is the goal of this PR?

- Visual UI overhaul
- UI theme selection

### What changes are included?

- Added a setting "UI Theme": Classic, Lyra
- The classic theme is the current Crosspoint theme
- The Lyra theme implements these mockups:
https://www.figma.com/design/UhxoV4DgUnfrDQgMPPTXog/Lyra-Theme?node-id=2003-7596&t=4CSOZqf0n9uQMxDt-0
by Discord users yagofarias, ruby and gan_shu
- New functions in GFXRenderer to render rounded rectangles, greyscale
fills (using dithering) and thick lines
- Basic UI components are factored into BaseTheme methods which can be
overridden by each additional theme. Methods that are not overridden
will fallback to BaseTheme behavior. This means any new
features/components in CrossPoint only need to be developed for the
"Classic" BaseTheme.
- Additional themes can easily be developed by the community using this
foundation

Medium](https://github.com/user-attachments/assets/518a9a6d-107a-4be3-9533-43a2b64b944b)



## Additional Context

- Only the Home, Library and main Settings screens have been implemented
so far, this will be extended to the transfer screens and chapter
selection screen later on, but we need to get the ball rolling somehow
:)
- Loading extra covers on the home screen in the Lyra theme takes a
little more time (about 2 seconds), I added a loading bar popup (reusing
the Indexing progress bar from the reader view, factored into a neat UI
component) but the popup adds ~400ms to the loading time.
- ~~Home screen thumbnails will need to be generated separately for each
theme, because they are displayed in different sizes. Because we're
using dithering, displaying a thumb with the wrong size causes the
picture to look janky or dark as it does on the screenshots above. No
worries this will be fixed in a future PR.~~ Thumbs are now generated
with a size parameter
- UI Icons will need to be implemented in a future PR.

f4df513bf3 feat(ui): change popup logic (#442)
## Summary

* refactors Indexing popups into ScreenComponents (they had different
implementations in different files)
* removes Indexing popup for small chapters
* only show Indexing popup (without progress bar) for large chapters
(using same minimum file size condition as for progress bar before)

## Additional Context

* Having to show even single popup message and redraw the screen slows
down the flow significantly
* Testing results:
    * Opening large chapter with progress bar - 11 seconds
* Same chapter without progress bar, only single Indexing popup - 5
seconds

f935b59a41 feat: Add reading menu and delete cache function (#433)
## Summary

* Adds a menu in the Epub reader
* The Chapter selection is moved there to pos 1 (so it can be reached by
double tapping the confirm button)
* A Go Home is there, too
* Most significantly, a function "Delete Book Cache" is added. This
returns to main (to avoid directly rebuilding cached items, eg. if this
is used to debug/develop other areas - and it's also easier ;))

Probably, the Sync function could now be moved from the Chapter
selection to this menu, too.

This PR adds HAL (Hardware Abstraction Layer) for display and GPIO

SD card HAL will be added via another PR, because it's a bit more
tricky.

e9c2fe1c87 feat: Add status bar option "Full w/ Progress Bar" (#438)
## Summary

* **What is the goal of this PR?** This PR introduces a new "Status Bar"
mode that displays a visual progress bar at the bottom of the screen,
providing readers with a graphical indication of their position within
the book.
* **What changes are included?** 

* **Settings**: Updated SettingsActivity to expand the "Status Bar"
configuration with a new option: Full w/ Progress Bar.
* **EPUB Reader**: Modified EpubReaderActivity to calculate the global
book progress and render a progress bar at the bottom of the viewable
area when the new setting is active.
* **TXT Reader**: Modified TxtReaderActivity to implement similar
progress bar rendering logic based on the current page and total page
count.

## Additional Context

* The progress bar is rendered with a height of 4 pixels at the very
bottom of the screen (adjusted for margins).
* The feature reuses the existing renderStatusBar logic but
conditionally draws the bar instead of (or in addition to) other
elements depending on the specific implementation details in each
reader.
  * Renamed existing 'Full' mode to 'Full w/ Percentage'
  * Added new 'Full w/ Progress Bar' option

b8ebcf5867 fix: remove decimal places from progress % (#507)
## Summary

Addresses
https://github.com/crosspoint-reader/crosspoint-reader/issues/504

- Reverts book progress % to showing as an integer instead of with a
decimal place
- This was changed to 1 decimal point of precision in
https://github.com/crosspoint-reader/crosspoint-reader/pull/232 from
what I can tell
- As this wasn't the primary intention of that PR, I'm assuming it was
left in accidentally

IMO having a decimal place of precision is too much for something as
vague as book completion percent. This de-clutters the status bar and
prevents extra updates as you change pages.

e548bfc0e1 My Library: Tab bar w/ Recent Books + File Browser (#250)
# Summary

This PR introduces a reusable Tab Bar component and combines the Recent
Books and File Browser into a unified tabbed page called "My Library"
accessible from the Home screen.

## Features
### New Tab Bar Component
A flexible, reusable tab bar component added to `ScreenComponents` that
can be used throughout the application.

### New Scroll Indicator Component
A page position indicator for lists that span multiple pages.
**Features:**
- Up/down arrow indicators
- Current page fraction display (e.g., "1/3")
- Only renders when content spans multiple pages

### My Library Activity
A new unified view combining Recent Books and File Browser into a single
tabbed page.

**Tabs:**
- **Recent** - Shows recently opened books
- **Files** - Browse SD card directory structure

**Navigation:**
- Up/Down or Left/Right: Navigate through list items
- Left/Right (when first item selected): Switch between tabs
- Confirm: Open selected book or enter directory
- Back: Go up directory (Files tab) or return home
- Long press Back: Jump to root directory (Files tab)

**UI Elements:**
- Tab bar with selection indicator
- Scroll/page indicator on right side
- Side button hints (up/down arrows)
- Dynamic bottom button labels ("BACK" in subdirectories, "HOME" at
root)

## Tab Bar Usage
The tab bar component is designed to be reusable across different
activities. Here's how to use it:

### Basic Example
```cpp
#include "ScreenComponents.h"
void MyActivity::render() const {
  renderer.clearScreen();
  
  // Define tabs with labels and selection state
  std::vector<TabInfo> tabs = {
    {"Tab One", currentTab == 0},   // Selected when currentTab is 0
    {"Tab Two", currentTab == 1},   // Selected when currentTab is 1
    {"Tab Three", currentTab == 2}  // Selected when currentTab is 2
  };
  
  // Draw tab bar at Y position 15, returns height of the tab bar
  int tabBarHeight = ScreenComponents::drawTabBar(renderer, 15, tabs);
  
  // Position your content below the tab bar
  int contentStartY = 15 + tabBarHeight + 10; // Add some padding
  
  // Draw content based on selected tab
  if (currentTab == 0) {
    renderTabOneContent(contentStartY);
  } else if (currentTab == 1) {
    renderTabTwoContent(contentStartY);
  } else {
    renderTabThreeContent(contentStartY);
  }
  
  renderer.displayBuffer();
}
```

8824c87490 feat: dict based Hyphenation (#305)
## Summary

* Adds (optional) Hyphenation for English, French, German, Russian
languages

## Additional Context

* Included hyphenation dictionaries add approximately 280kb to the flash
usage (German alone takes 200kb)
* Trie encoded dictionaries are adopted from hypher project
(https://github.com/typst/hypher)
* Soft hyphens (and other explicit hyphens) take precedence over
dict-based hyphenation. Overall, the hyphenation rules are quite
aggressive, as I believe it makes more sense on our smaller screen.

By disabling the Text Anti-Aliasing in the settings, you can get faster
black-and-white page turns that work exactly like the stock firmware,
instead of having an additional flash after rendering (see issue linked
above for example).

Add a new user setting for paragraph alignment, instead of hard-coding
full justification.

* **What changes are included?**

One new line in the settings screen, with 4 options
(justify/left/center/right). Default is justified since that's what it
was already. I personally only wanted to disable justification and use
"left", but I included the other options for completeness since they
were already supported.
