## Summary
Extracted some changes from
https://github.com/crosspoint-reader/crosspoint-reader/pull/500 to make
reviewing easier
This PR adds HAL (Hardware Abstraction Layer) for display and GPIO
components, making it easier to write a stub or an emulated
implementation of the hardware.
SD card HAL will be added via another PR, because it's a bit more
tricky.

For the Files screen, I have not made any changes on purpose. For the
Recents screen, we now display the Book title and author. If it is a
file with no epub metadata like txt or md, we display the file name
without the file extension.

## Summary
Finally, I have received my device and got to chance to work on OTA.
https://github.com/crosspoint-reader/crosspoint-reader/issues/176
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Existing OTA functionality is very buggy, many of times (I would say 8
out of 10) are end up with fail for me. When the time that it works it
is very slow and take ages. For others looks like end up with crash or
different issues.
* **What changes are included?**
To be honest, I'm not familiar with Arduino APIs of OTA process, but
looks like not good as much esp-idf itself. I always found Arduino APIs
very bulky for esp32. Wrappers and wrappers.
## Additional Context
Right now, OTA takes ~ 3min 10sec (of course depends on size of .bin
file). Can be tested with playing version info inside from
`platform.ini` file.
```
[crosspoint]
version = 0.14.0

## Summary
Optimizes EPUB metadata indexing for large books (2000+ chapters) from
~30 minutes to ~50 seconds by replacing O(n²) algorithms with O(n log n)
hash-indexed lookups.
Fixes#134
## Problem
Three phases had O(n²) complexity due to nested loops:
| Phase | Operation | Before (2768 chapters) |
|-------|-----------|------------------------|
| OPF Pass | For each spine ref, scan all manifest items | ~25 min |
| TOC Pass | For each TOC entry, scan all spine items | ~5 min |
| buildBookBin | For each spine item, scan ZIP central directory | ~8.4
min |
Total: **~30+ minutes** for first-time indexing of large EPUBs.
## Solution
Replace linear scans with sorted hash indexes + binary search:
- **OPF Pass**: Build `{hash(id), len, offset}` index from manifest,
binary search for each spine ref
- **TOC Pass**: Build `{hash(href), len, spineIndex}` index from spine,
binary search for each TOC entry
- **buildBookBin**: New `ZipFile::fillUncompressedSizes()` API - single
ZIP central directory scan with batch hash matching
All indexes use FNV-1a hashing with length as secondary key to minimize
collisions. Indexes are freed immediately after each phase.
## Results
**Shadow Slave EPUB (2768 chapters):**
| Phase | Before | After | Speedup |
|-------|--------|-------|---------|
| OPF pass | ~25 min | 10.8 sec | ~140x |
| TOC pass | ~5 min | 4.7 sec | ~60x |
| buildBookBin | 506 sec | 34.6 sec | ~15x |
| **Total** | **~30+ min** | **~50 sec** | **~36x** |
**Normal EPUB (87 chapters):** 1.7 sec - no regression.
## Memory
Peak temporary memory during indexing:
- OPF index: ~33KB (2770 items × 12 bytes)
- TOC index: ~33KB (2768 items × 12 bytes)
- ZIP batch: ~44KB (targets + sizes arrays)
All indexes cleared immediately after each phase. No OOM risk on
ESP32-C3.
## Note on Threshold
All optimizations are gated by `LARGE_SPINE_THRESHOLD = 400` to preserve
existing behavior for small books. However, the algorithms work
correctly for any book size and are faster even for small books:
| Book Size | Old O(n²) | New O(n log n) | Improvement |
|-----------|-----------|----------------|-------------|
| 10 ch | 100 ops | 50 ops | 2x |
| 100 ch | 10K ops | 800 ops | 12x |
| 400 ch | 160K ops | 4K ops | 40x |
If preferred, the threshold could be removed to use the optimized path
universally.
## Testing
- [x] Shadow Slave (2768 chapters): 50s first-time indexing, loads and
navigates correctly
- [x] Normal book (87 chapters): 1.7s indexing, no regression
- [x] Build passes
- [x] clang-format passes
## Files Changed
- `lib/Epub/Epub/parsers/ContentOpfParser.h/.cpp` - OPF manifest index
- `lib/Epub/Epub/BookMetadataCache.h/.cpp` - TOC index + batch size
lookup
- `lib/ZipFile/ZipFile.h/.cpp` - New `fillUncompressedSizes()` API
- `lib/Epub/Epub.cpp` - Timing logs
<details>
<summary><b>Algorithm Details</b> (click to expand)</summary>
### Phase 1: OPF Pass - Manifest to Spine Lookup
**Problem**: Each `<itemref idref="ch001">` in spine must find matching
`<item id="ch001" href="...">` in manifest.
```
OLD: For each of 2768 spine refs, scan all 2770 manifest items
= 7.6M string comparisons
NEW: While parsing manifest, build index:
{ hash("ch001"), len=5, file_offset=120 }
Sort index, then binary search for each spine ref:
2768 × log₂(2770) ≈ 2768 × 11 = 30K comparisons
```
### Phase 2: TOC Pass - TOC Entry to Spine Index Lookup
**Problem**: Each TOC entry with `href="chapter0001.xhtml"` must find
its spine index.
```
OLD: For each of 2768 TOC entries, scan all 2768 spine entries
= 7.6M string comparisons
NEW: At beginTocPass(), read spine once and build index:
{ hash("OEBPS/chapter0001.xhtml"), len=25, spineIndex=0 }
Sort index, binary search for each TOC entry:
2768 × log₂(2768) ≈ 30K comparisons
Clear index at endTocPass() to free memory.
```
### Phase 3: buildBookBin - ZIP Size Lookup
**Problem**: Need uncompressed file size for each spine item (for
reading progress). Sizes are in ZIP central directory.
```
OLD: For each of 2768 spine items, scan ZIP central directory (2773 entries)
= 7.6M filename reads + string comparisons
Time: 506 seconds
NEW:
Step 1: Build targets from spine
{ hash("OEBPS/chapter0001.xhtml"), len=25, index=0 }
Sort by (hash, len)
Step 2: Single pass through ZIP central directory
For each entry:
- Compute hash ON THE FLY (no string allocation)
- Binary search targets
- If match: sizes[target.index] = uncompressedSize
Step 3: Use sizes array directly (O(1) per spine item)
Total: 2773 entries × log₂(2768) ≈ 33K comparisons
Time: 35 seconds
```
### Why Hash + Length?
Using 64-bit FNV-1a hash + string length as a composite key:
- Collision probability: ~1 in 2⁶⁴ × typical_path_lengths
- No string storage needed in index (just 12-16 bytes per entry)
- Integer comparisons are faster than string comparisons
- Verification on match handles the rare collision case

## 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

## Summary
This was originally a comment in #499, but I'm making it its own PR,
because it doesn't depend on anything there and then I can base that PR
on this one.
Currently, `drawBitmap` is used for covers and sleep wallpaper, and
`drawImage` is used for the boot logo. `drawBitmap` goes row by row and
pixel by pixel, so it respects the renderer orientation. `drawImage`
just calls the `EInkDisplay`'s `drawImage`, which works in the eink
panel's native display orientation.
`drawImage` rotates the x,y coordinates where it's going to draw the
image, but doesn't account for the fact that the northwest corner in
portrait orientation becomes, the southwest corner of the image
rectangle in the native orientation. The boot and sleep activities
currently work around this by calculating the north*east* corner of
where the image should go, which becomes the northwest corner after
`rotateCoordinates`.
I think this wasn't really apparent because the CrossPoint logo is
rotationally symmetrical. The `EInkDisplay` `drawImage` always draws the
image in native orientation, but that looks the same for the "X" image.
If we rotate the origin coordinate in `GfxRenderer`'s `drawImage`, we
can use a much clearer northwest corner coordinate in the boot and sleep
activities. (And then, in #499, we can actually rotate the boot screen
to the user's preferred orientation).
This does *not* yet rotate the actual bits in the image; it's still
displayed in native orientation. This doesn't affect the
rotationally-symmetric logo, but if it's ever changed, we will probably
want to allocate a new `u8int[]` and transpose rows and columns if
necessary.
## Additional Context
I've created an additional branch on top of this to demonstrate by
replacing the logo with a non-rotationally-symmetrical image:
<img width="128" height="128" alt="Cat-in-a-pan-128-bw"
src="https://github.com/user-attachments/assets/d0b239bc-fe75-4ec8-bc02-9cf9436ca65f"
/>
https://github.com/crosspoint-reader/crosspoint-reader/compare/master...maeveynot:rotated-cat
(many thanks to https://notisrac.github.io/FileToCArray/)
As you can see, it is always drawn in native orientation, which makes it
sideways (turned clockwise) in portrait.

## Summary
- Update README with the list of supported languages for EPUB files.
- Update USER_GUIDE with an extended list of supported and unsupported
languages.
## Additional Context
For weeks, I thought this firmware only supported English, because I
remember you saying that full language support would only be possible
after implementing proper font rendering. I also remember mentioning a
separate Korean fork, Vietnamese issues and so on.
All of this made it clear that this system doesn't support my languages.
I was surprised when I saw a Reddit post with a photo of a book in my
native language. Only then I did learn that such languages are
supported. Therefore, mentioning the supported languages would help
future buyers and new users.

## Summary
Fix https://github.com/crosspoint-reader/crosspoint-reader/issues/288
Based on my observation, it seems like the problem was that
`inputManager.isPressed(InputManager::BTN_POWER)` takes a bit of time
after waking up to report the correct value. I haven't tested this
behavior with a standalone ESP32C3, but if you know more about this,
feel free to comment.
However, if we just want short press, I think it's enough to check for
wake up source. If we plan to allow multiple buttons to wake up in the
future, may consider using ext1 / `esp_sleep_get_ext1_wakeup_status()`
to allow identify which pin triggered wake up.
Note that I'm not particularly experienced in esp32 developments, just
happen to have prior knowledge hacking esphome.

## Summary
* Fixes#519
* Refactors repeated code into new function:
`ChapterHtmlSlimParser::flushPartWordBuffer()`
## Additional Context
* The `<br/>` tag is self closing and _in-line_, so the existing logic
for closing block tags does not get applied to `<br/>` tags.
* This PR adds the _in-line_ logic to:
* Flush the word preceding the `<br/>` tag from `partWordBuffer` to
`currentTextBlock` before calling `startNewTextBlock`
* **New function**: `ChapterHtmlSlimParser::flushPartWordBuffer()`
* **Purpose**: Consolidates the logic for flushing `partWordBuffer` to
`currentTextBlock`
* **Impact**: Simplifies `ChapterHtmlSlimParser::characterData(…)`,
`ChapterHtmlSlimParser::startElement(…)`, and
`ChapterHtmlSlimParser::endElement(…)` by integrating reused code into
single function

Our esp32 consistently dropped the last few packets of the TCP transfer
in the old implementation. Only about 1/5 transfers would complete. I've
refactored that entire system into an actual Calibre Device Plugin that
basically uses the exact same system as the web server's file transfer
protocol. I kept them separate so that we don't muddy up the existing
file transfer stuff even if it's basically the same at the end of the
day I didn't want to limit our ability to change it later.
I've also added basic auth to OPDS and renamed that feature to OPDS
Browser to just disassociate it from Calibre.

- 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.

* Add additional punctuation marks to the list of characters that can be
immediately followed by a line break even where there is no explicit
space
## Additional Context
* Huge appreciation to @osteotek for his amazing work on hyphenation.
Reading on the device is so much better now.
* I am getting bad line breaks when ellipses (…) are between words and
book file does not explicitly include some kind of breaking space.
* Per
[discussion](https://github.com/crosspoint-reader/crosspoint-reader/pull/305#issuecomment-3765411406),
several new characters are added in this PR to the `isExplicitHyphen`
list to allow line breaks immediately after them:
Character | Unicode | Usage | Why include it?
-- | -- | -- | --
Solidus (Slash) | U+002F | / | Essential for breaking URLs and "and/or"
constructs.
Backslash | U+005C | \ | Critical for technical text, file paths, and
coding documentation.
Underscore | U+005F | _ | Prevents "runaway" line lengths in usernames
or code snippets.
Middle Dot | U+00B7 | · | Acts as a semantic separator in dictionaries
or stylistic lists.
Ellipsis | U+2026 | … | Prevents justification failure when dialogue
lacks following spaces.
Midline Horizontal Ellipsis | U+22EF | ⋯ | Useful for mathematical
sequences and technical notation.
### Example:
This shows an example of what line breaking looks like *with* this PR.
Note the line break after "matter…" (which would not previously have
been allowed). It's particularly important here because the book
includes non-breaking spaces in "Mr. Aldrich" and "Mr. Rockefeller."

## Summary
When uploading or downloading an updated ebook from SD/WebUI/OPDS with
same the filename the `.crosspoint` cache is not cleared. This can lead
to issues with the Table of Contents and hangs when switching between
chapters.
I encountered this issue in two places:
- When I need to do further ePub cleaning using Calibre after I load an
ePub and find that some of its formatting should be cleaned up. When I
reprocess the same book and want to place it back in the same location I
need a way to invalidate the cache.
- When syncing RSS feed generated epubs. I generate news ePubs with
filenames like `news-outlet.epub` and so every day when I fetch new news
the crosspoint cache needs to be cleared to load that file.
This change offers the following features:
- On web uploads, if the file already exists, the cache for that file is
cleared
- On OPDS downloads, if the file already exists, the cache for that file
is cleared
- There's now an action for `Clear Cache` in the Settings page which can
clear the cache for all books

# 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();
}
```

## Summary
* **What is the goal of this PR?** (e.g., Fixes a bug in the user
authentication module, Implements the new feature for
file uploading.)
As we get more settings, I think it makes sense to do categories for
them. This just allows users to find the settings easier and navigate to
them.
* **What changes are included?**
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).

## Summary
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
- Implements a fix to truncate chapter names that exceeds display width
* **What changes are included?**
- Implements a fix to truncate chapter names that exceeds display width
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
- Prior to the fix, if the book contains multiple chapters with names
longer than the display width, there is a noticeable delay when
scrolling through the list of chapters.

## 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.

The current behavior of rendering `?` for an unknown Unicode character
can be hard to distinguish from a typo. Use the standard Unicode
"replacement character" instead, that's what it's designed for:
https://en.wikipedia.org/wiki/Specials_(Unicode_block)
I'm making this PR as a draft because I'm not sure I did everything that
was needed to change the character set covered by the fonts. Running
that script is in its own commit. If this is proper, I'll rebase/squash
into one commit and un-draft.
