✏️ 2026-11-03 | A Rename Form for Re-theming the Game 📋

🧑‍💻 Author’s Note

👋 Hello! The last two posts brainstormed whole new worlds for the game’s 60 cards: first three very different settings, then three arcane decks.
🧭 Both were tables in markdown. Issue #20 asked for something better for humans: a form, right inside the game, where you can type new names next to the cards they belong to and copy the result.
🛠️ This post describes the new Rename tab in the settings menu and how it is built.

🎯 What the Form Does

• ⚙️ Open Settings → Rename. It sits next to the Kingdom tab and looks a lot like it.
• 🔤 A Terms section has an input for each core word in the game: the title, Game, Player, Turn, Action, Buy, Card, Money, Victory Point, the card types (Treasure, Victory, Curse, Attack, Reaction), the places cards live (Hand, Deck, Discard, Trash, Supply, Kingdom) and the three phases.
• 🃏 A Cards section lists all 60 registered cards. Each card is drawn with the same component the game uses, next to inputs for its name, its text (if it has a special effect) and its reaction text (if it has one). The current wording sits above each input and fills its placeholder, so you can always see what you’re replacing.
• 👀 The card preview updates as you type. Rename Copper to Spark and the card in the form says Spark.
• 📋 Copy N proposed change(s) puts a short mapping on the clipboard. Fields that are blank, or that only repeat the current text, are left out:

Terms:  
- Action → Cast  
Cards:  
- Copper → Spark  
- Chapel text → Burn up to 4 scrolls from your hand  
- Secret Chamber reaction → Ward yourself against hexes.  

• 💾 Drafts are saved to local storage as you type, so a reload doesn’t lose an hour of naming. Clear all starts over.

🧱 How It Is Built

🧩 A small domain module

📦 Everything about re-theming lives in src/Data/Retheme.purs, which has no UI code in it:

• 🏷️ RenameTarget is a sum type for each thing you can rename: Term, CardName, CardText and ReactionText. Card targets are keyed by the card’s current name, which is also how cards are identified in code.
• 📚 Renameable pairs a target with its current text. cardRenameables gets these from a Card record, so a card with no special effect gets no text field, and only cards with a reaction get a reaction field.
• 🗺️ Proposals is a Map RenameTarget String. Clearing a field removes its entry instead of storing an empty string.
• 🔍 proposedChange is the one rule that decides what counts as a change. It collapses whitespace, then keeps the text only if it isn’t empty and differs from the current wording. The copied mapping, the change count on the button and the live card preview all use it, so they always agree.
• 🎨 previewCard applies the proposals to a Card, which is how the form shows a renamed card without touching any game logic.

🖥️ A thin UI

🪟 src/UI/Rename.purs renders the form from that module. The rest of the app needed only small changes:

• ➕ a RenameTab in SettingsTab
• ✉️ three new actions: ProposeRename, CopyRenameMapping and ClearRenameProposals
• 💾 a rename_proposals key in local storage, kept global like other personal preferences
• 📋 the existing copyToClipboard helper, which the invite link and bug report buttons already use

🧪 Testing

✅ A new Re-theming test section (test/Retheme.purs) mostly uses QuickCheck properties over random proposals:

• 🆔 every renameable element has a unique target, and every registered card can be renamed
• 🔁 a proposal reads back exactly as typed, a blank proposal removes the entry, and proposals survive a JSON round trip through storage
• 📏 the mapping has exactly one line per counted change, and every line is either a section header or a - label → proposed change
• ⚖️ for any element and any text, the mapping lists it if and only if the normalized text is a new name
• 🧹 whitespace normalization is idempotent and never leaves a line break, so a pasted multi-line description still takes one line
• 🃏 previewing with no proposals leaves every card unchanged, and the preview shows a proposed name exactly when it is a real change

🌐 I also checked it in a real browser: I typed into term, name, text and reaction fields, read the clipboard after pressing Copy, reloaded to check the draft was still there, cleared it, and confirmed the layout fits a 380px-wide phone screen without scrolling sideways.

🔭 What’s Next

• 🎭 Once a direction is chosen, the copied mapping is meant to be easy to apply to src/Data/Cards.purs and the UI text.
• 🔀 A later step could load a mapping back into the form, or let both themes exist side by side as the re-theming issue suggests.
