read @HACKING.md to understand the code. Then fix the headings in the sheduleView - we always need one or two headings (for day 1/2 or both). Switch Both Days toggle in the options Menu (@main.lua) to a OptionsMenu playdate.menu:addOptionsMenuItem(title, options, [initalValue], callback)

Creates a menu item that allows the player to cycle through a set of options.

title will be the title displayed by the menu item.

options should be an array-style table of strings representing the states the menu item can have. Due to limited horizontal space, the option strings and title should be kept short for this type of menu item.

initialValue can optionally be set to any of the values in the options array.

If the value of this menu item is changed while the system menu is open, callback will be called when the menu is closed, before playdate.gameWillResume is called. The callback function will be passed one string argument indicating the currently selection option.

If the returned playdate.menu.item is nil, a second errorMessage return value will indicate the reason the operation failed. Playdate OS allows a maximum of three custom menu items to be added to the System Menu. . Ask questions if you have

The text for Day 1 header in csheduleView is always Day 2

Now both headers say Day 1

There are lots of different cases: a track can contain only Day 1 events and will be shown with Day 1 header if Both/Day 1 is selected. Similarly, a track containing only Day 2 events will be sohwn with day 2 header if both or day 2 is selected. If a track contains both days, it should be shown with both day 1 and day 2 headers. If we make a switch on the day from the options menu, and come back - we should reload the whole view. Further if the new selection is DAY 1 / DAY 2 and the current track does not have any events in the current selection - we should switch to Main Track and reload the whole view. The previous bug is still present. With both selected, main track now says DAY 1 {day 1 events} DAY 1 {day 2 events}. FIX IT, you are smarter, ultrathink

Grid view

playdate.ui.gridview provides a means for drawing a grid view composed of cells, and optionally sections with section headers. You must import CoreLibs/ui to use gridview.

Some notes:

playdate.ui.gridview uses playdate.timer internally, so playdate.timer.updateTimers() must be called in the main playdate.update() function.

If the gridview’s cell width is set to 0, cells will be drawn the same width as the table (minus any padding).

Section headers always draw the full width of the grid (minus padding), and do not scroll horizontally along with the rest of the content.

playdate.ui.gridview.new(cellWidth, cellHeight)

Returns a new playdate.ui.gridview with cells sized cellWidth, cellHeight. (Sizes are in pixels.) If cells should span the entire width of the grid (as in a list view), pass zero (0) for cellWidth. Drawing playdate.ui.gridview:drawCell(section, row, column, selected, x, y, width, height)

Override this method to draw the cells in the gridview. selected is a boolean, true if the cell being drawn is the currently-selected cell. playdate.ui.gridview:drawSectionHeader(section, x, y, width, height)

Override this method to draw section headers. This function will only be called if the header height has been set to a value greater than zero (0). playdate.ui.gridview:drawHorizontalDivider(x, y, width, height)

Override this method to customize the drawing of horizontal dividers. This function will only be called if the horizontal divider height is greater than zero (0) and at least one divider has been added. playdate.ui.gridview:drawInRect(x, y, width, height)

Draws the gridview in the specified rect. Ideally this should be called on every playdate.update() to accommodate scrolling. playdate.ui.gridview.needsDisplay

This read-only variable returns true if the gridview needs to be redrawn. This can be used to help optimize drawing in your app. Keep in mind that a gridview cannot know all reasons it may need to be redrawn, such as changes in your drawing callback functions, coordinate or size changes, or overlapping drawing, so you may need to additionally redraw at other times. Conditionally draw a grid view

if myGridView.needsDisplay == true then myGridView:drawInRect(x, y, w, h) end

Configuration playdate.ui.gridview:setNumberOfSections(num)

Sets the number of sections in the grid view. Each section contains at least one row, and row numbering starts at 1 in each section. playdate.ui.gridview:getNumberOfSections()

Returns the number of sections in the grid view. playdate.ui.gridview:setNumberOfRowsInSection(section, num)

Sets the number of rows in section. playdate.ui.gridview:getNumberOfRowsInSection(section)

Returns the number of rows in section. playdate.ui.gridview:setNumberOfColumns(num)

Sets the number of columns in the gridview. 1 by default. playdate.ui.gridview:getNumberOfColumns()

Returns the number of columns in the gridview. 1 by default. playdate.ui.gridview:setNumberOfRows(…​)

Convenience method for list-style gridviews, or for setting the number of rows for multiple sections at a time. Pass in a list of numbers of rows for sections starting from section 1. playdate.ui.gridview:setCellSize(cellWidth, cellHeight)

Sets the size of the cells in the gridview. If cells should span the entire width of the grid (as in a list view), pass zero (0) for cellWidth. playdate.ui.gridview:setCellPadding(left, right, top, bottom)

Sets the amount of padding around cells. playdate.ui.gridview:setContentInset(left, right, top, bottom)

Sets the amount of space the content is inset from the edges of the gridview. Useful if a background image is being used as a border. playdate.ui.gridview:getCellBounds(section, row, column, [gridWidth])

Returns multiple values (x, y, width, height) representing the bounds of the cell, not including padding, relative to the top-right corner of the grid view.

If the grid view is configured with zero width cells (see playdate.ui.gridview:new), gridWidth is required, and should be the same value you would pass to playdate.ui.gridview:drawInRect. playdate.ui.gridview:setSectionHeaderHeight(height)

Sets the height of the section headers. 0 by default, which causes section headers not to be drawn. playdate.ui.gridview.getSectionHeaderHeight()

Returns the current height of the section headers. playdate.ui.gridview:setSectionHeaderPadding(left, right, top, bottom)

Sets the amount of padding around section headers. playdate.ui.gridview:setHorizontalDividerHeight(height)

Sets the height of the horizontal dividers. The default height is half the cell height specified when creating the grid view. playdate.ui.gridview:getHorizontalDividerHeight()

Returns the height of the horizontal dividers. playdate.ui.gridview:addHorizontalDividerAbove(section, row)

Causes a horizontal divider to be drawn above the specified row. Drawing can be customized by overriding playdate.ui.gridview:drawHorizontalDivider. playdate.ui.gridview:removeHorizontalDividers()

Removes all horizontal dividers from the grid view. . Switch to gridView sections for each Day.

When I switch left and right to a different track, I should scroll back to the top.

The item selected is correct on the switch, but the items drawn are not correct. So the selection is not shown till I actually scroll up or down

switch to "quizshow.fnt" in the main menu

Load the fonts/xmen font for showing the time. Use regular font for the remaining event summary in the scheduleView

Can we increase teh font size a little for the time?

Now we create the map state and views. Rotate through maps/{CAMPUS,K1,H}.png files using left and right keys. The files are bigger than 400x200, we want to support a pan based view using the arrow keys. Pressing B takes you back to the main menu, and pressing A takes you to the next file.

Support long press on a direction pan which should happen every tick automtaically

Change the QR popup screen to be more generic - It should be able to display more than just events. What it needs is a type (event) title (event summary), subtitle (event location) - optional, description (event abstract), an ID (that can be used for the qr if file is present), take a boolean called: saveAble. The UI gets 2 changes: add a circular button underneath the QR code (or at the bottom if no QR) in black background that says (B) BACK. Further, just above the QR code if saveAble is true, then show a (A) [SAVE] button, where SAVE has a rounded rectangle around it in 2 px. On pressing A, toggle the SAVE and persist it as a type,ID tuple. Since QR is now a genericview, we want to reuse it for our ABOUT screen. Show the app title, a small description (Kurbelfahrplan is a FOSDEM schedule app for the playdate made by Nemo. Made using Claude Code with lots of <3 in Berlin. Come find the author at the FOSSUnited+FLOSS/fund booth for an easter egg. Set id=ABOUT, so that ABOUT.png loads. saveAble will be false.

Detect the MAX(height of the title and subtitle from the return values) and use that to align the description. The bottom of the description should sit close to the border. The input handlers get weird after I quit the ABOUTpopup screen - I reach the main menu but none of the keys have any effect. Fix that. And finally, the B back button text should be: (B) -> black background, white text followed by regular BACK text in white background no border and black text.

section headers in the stand listings should not be selectable.

Add a new item in main menu called SAVED. Show a listing with the title Saved Talks, and always display talks from both days here irrespective of the setting and with both the Day 1 and Day 2 header.
