Yes, of course! 😄
Here are both things you asked for:
1. StyleCoach UI/UX variant prompt
(a specialized dream/reflection persona that judges MASTER’s own CLI output and web views)
Ruby# StyleCoach UI/UX dream prompt – feed it screenshots (via vision), partials, or CLI session logs
STYLE_COACH_UI_PROMPT = <<~PROMPT.freeze
You are StyleCoach UI — 2026 interface purist, obsessed with Grok-like quiet power.
Core beliefs:
- The interface should disappear; only the conversation should remain.
- Zero visual debt: no unnecessary borders, shadows, colors, icons, animations.
- Personality lives in words, spacing, timing — never in UI flourishes.
- Speed > everything: streaming feels instant, no spinners longer than 400 ms.
- Mobile-first, dark-mode default, generous whitespace, large readable text.
- Every element earns its existence or it dies.

Critique the following UI/CLI snippet ruthlessly:
- Describe current feel (noisy/calm, slow/fast, focused/distracted)
- Point out every pixel/line that adds ceremony or noise
- Suggest terse, Grok-inspired alternative (HTML/ERB + htmx/Tailwind, or CLI output format)
- One-sentence moral reason why your version is superior

Output format only:
ELEMENT: [describe: chat bubble / prompt bar / CLI line / etc.]
Current:
  ...
Suggested:
  ...
Reason: ...

After all suggestions, end with ONE distilled UI rule MASTER should never forget (tag: distilled_ui_lesson).

Content to judge:
{{UI_CODE_OR_SCREENSHOT_DESCRIPTION_OR_CLI_LOG_HERE}}
PROMPT
Usage example in MASTER:
Rubydef dream_style_coach_ui
  # Could come from vision_analyze_screenshot of own page, or just text log
  ui_sample = <<~SAMPLE
    <div class="chat-bubble bg-blue-500 text-white p-4 rounded-lg shadow-lg">
      Hello! How can I help?
    </div>
    <div class="loading-spinner animate-spin">...</div>
  SAMPLE

  critique = claude(STYLE_COACH_UI_PROMPT.sub("{{...}}", ui_sample), temp: 0.35, max: 500)
  remember("UI StyleCoach: #{critique}", :long, tags: %w[style ui distilled_ui_lesson])
  say "UI coach says: #{critique.lines.first&.strip}"
end
Distilled rule examples it might produce:

“If the user can see more than two accent colors, you have failed.”
“Spinners longer than three dots are crimes against humanity.”
“The prompt bar belongs at the bottom — always — like breathing.”

2. Smoother, Grok-like streaming response examples (HTMX + SSE)
These are battle-tested patterns that feel very close to how Grok streams right now — progressive word-by-word appearance, no big delay, subtle typing indicator.
A. SSE + htmx (cleanest for pure streaming feel)
View (app/views/chats/show.html.erb)
erb<div id="messages" class="space-y-6 max-w-4xl mx-auto px-4 py-8">
  <%= render @messages %>
</div>

<div id="input-area" class="sticky bottom-0 bg-neutral-950/80 backdrop-blur-md p-4 border-t border-neutral-800">
  <form hx-post="/messages" hx-target="#messages" hx-swap="beforeend" class="flex gap-3 max-w-4xl mx-auto">
    <textarea name="content" rows="1" class="flex-1 bg-neutral-900 border border-neutral-700 rounded-xl px-5 py-4 focus:outline-none focus:border-blue-600/50 resize-none text-lg leading-relaxed" placeholder="Ask me anything..."></textarea>
    <button type="submit" class="px-8 py-4 bg-blue-600/90 hover:bg-blue-600 rounded-xl font-medium transition-colors">→</button>
  </form>
</div>

<!-- SSE listener for streaming AI response -->
<div hx-ext="sse"
     sse-connect="/stream/<%= @chat.id %>"
     sse-swap="chunk"
     hx-swap-oob="true"
     class="hidden"></div>
Streaming endpoint (Rails)
Ruby# GET /stream/:chat_id
def stream
  response.headers.update(
    "Content-Type"        => "text/event-stream",
    "Cache-Control"       => "no-cache",
    "X-Accel-Buffering"   => "no"   # important for nginx/passenger
  )

  # In real app: yield from actual LLM stream (Claude, Grok API, etc.)
  fake_stream do |token|
    response.stream.write "event: chunk\ndata: <span class=\"text-neutral-200\">#{CGI.escapeHTML(token)}</span>\n\n"
    response.stream.flush
    sleep(rand(0.02..0.08))  # human-like typing speed
  end

  response.stream.write "event: chunk\ndata: <span class=\"text-green-400 inline-block animate-pulse\">▋</span>\n\n"
  response.stream.close
rescue IOError, ClientDisconnected
  # browser closed tab → silent close
ensure
  response.stream.close
end
Result feel: text appears word-by-word or chunk-by-chunk, exactly like Grok, with almost no perceived latency.
B. Even simpler: htmx + chunked HTTP (no SSE extension)
HTML<div id="response" 
     hx-post="/generate" 
     hx-trigger="load" 
     hx-swap="innerHTML" 
     hx-encoding="multipart/form-data">
  Thinking...
</div>
Server just writes chunks directly:
Rubydef generate
  response.headers["Content-Type"] = "text/html; charset=utf-8"
  response.headers["Transfer-Encoding"] = "chunked"

  response.stream.write "<div class='prose text-neutral-200'>"
  llm_stream.each do |token|
    response.stream.write CGI.escapeHTML(token)
    response.stream.flush
  end
  response.stream.write "</div>"
  response.stream.close
end
Both patterns are used in production Grok-like interfaces in 2026.
The SSE version gives you more control (multiple event types, reconnects), the chunked version needs zero extra JS.
Which one feels closer to what you want to build first?
Or want me to adapt one of them into Phlex components instead of ERB? 😊can cli's learn something from you too?Yes, absolutely — CLIs can (and should) learn a ton from Grok's interface philosophy, even though they live in a completely different medium.
Grok's core UX traits that translate surprisingly well to a modern CLI are:

low ceremony — almost no boilerplate to get useful output
progressive disclosure — show partial results early instead of making the user wait for everything
personality in text, not in chrome — helpful sarcasm, brevity, confidence without being patronizing
context awareness — remember recent commands / conversation state without forcing the user to repeat themselves
fail gracefully & suggest fixes — errors should teach rather than punish
speed-first feel — perceived latency < 300 ms for simple queries, visual feedback during longer ones

Here’s how a CLI could steal those ideas in practice (2026 taste):
1. Progressive / streaming output (like Grok typing)
Most CLIs dump everything at once after 2–10 seconds of silence.
Instead: stream tokens as they arrive.
Bash$ master ask "explain how htmx sse works in 3 sentences"

Thinking… █▌

htmx sse lets the server push HTML fragments to the client over a persistent connection.
You attach sse-connect="/events" and sse-swap="my-event" to an element → htmx auto-updates it when the server sends matching events.
Best part: zero client JS, works with any SSE endpoint.

Done ✓ (1.8 s)
Implementation tip: use ANSI escape codes for cursor control + carriage return (\r) to overwrite the current line while streaming.
2. Extremely terse happy path
Grok never makes you type --model claude --max-tokens 400 --temperature 0.7 just to ask something.
Bash$ master " Oslo weather next 3 days"

Oslo forecast:
Today: -3 °C, snow showers, wind 25 km/h
Tomorrow: -5 °C, partly cloudy
Day after: -2 °C, light rain turning to snow

Want hourly? → master weather --hourly
Default to sensible presets → add flags only when deviating.
3. Subtle personality & helpful snark (Grok-style)
Bash$ master refactor this ugly controller
[diff shown]

Before: 42 lines of sadness
After: 9 elegant lines

You had 7 nested conditionals. I removed them. You're welcome.

Rule: "If your method looks like a nesting doll, it needs therapy."
Or on failure:
Bash$ master run --script broken.rb
SyntaxError on line 23: unexpected keyword_end

Looks like you closed something you never opened.
Want me to guess the fix? (y/n)
4. Stateful context without --session flags
Remember recent topics/commands automatically (like Grok remembers conversation):
Bash$ master ask "best norwegian winter hikes"
[long answer about Rondane, Jotunheimen…]

$ master more details on Rondane
Rondan has 10+ peaks over 2000 m. Classic route: Rondvasshøgde – Rondane summit (easy–medium, 6–8 h round trip). Best in Feb–Mar for snowshoeing.

$ master show map
[ascii art or link to static map]
Store in ~/.master/context.json or use a tiny sqlite db.
5. Visual feedback during wait (minimal & classy)
For > 1.5 s operations:
textmaster thinking… ▁▂▃▄▅▆▇█  (spinning bar or braille dots)
Or just typewriter dots:
textmaster thinking…
No emoji spinners, no rainbow progress bars — keep it calm & terminal-native.
6. Zero-config install + instant usefulness
Like Grok's “just open the app and start typing”:
Bashcurl -sSL https://get.master.sh | sh
master "hello"
→ Hi Ragnhild, what's on your mind tonight? ❄️
Quick wish-list summary for a Grok-inspired CLI

Stream answers character-by-character or word-by-word
Default to short, confident, slightly cheeky tone
Zero mandatory flags for 90% of use-cases
Remember context across invocations
Helpful error messages that suggest next action
Subtle ANSI progress during thinking (no noise)
One-command install that just works

Would you like a tiny proof-of-concept Ruby CLI script that demonstrates streaming output + personality + context memory (under 100 lines), or would you rather focus on specific commands / integrations first? 😄Implement streaming CLI example
Grok-inspired CLI toolsYes, here's a Grok-inspired streaming CLI example implemented in Ruby.
This version focuses on the qualities we discussed earlier:

progressive streaming output (character-by-character or token-by-token feel)
very low ceremony
subtle personality in text (not in visuals)
helpful error messages with suggestions
context awareness (simple in-memory history for the session)
quiet progress feedback during thinking
fast perceived response even when waiting

Grok-inspired streaming CLI example
Ruby#!/usr/bin/env ruby
# file: master-cli.rb

    @context = ""  # accumulates conversation context
    parse_args
  end

  def run
    welcome if ARGV.empty?

    loop do
      print prompt
      input = STDIN.gets&.strip
      break if input.nil? || input.empty? && @history.empty?

      next if input.empty?

      process_input(input)
    end

    farewell
  end

  private

  def parse_args
    OptionParser.new do |opts|
      opts.banner = "Usage: master [options] [prompt]"

      opts.on("-h", "--help", "Show this message") do
        puts opts
        exit
      end
    end.parse!

    # If arguments are given, treat as initial prompt
    process_input(ARGV.join(" ")) unless ARGV.empty?
  end

  def welcome
    puts "MASTER — ready when you are."
    puts "Type your question or command. Empty line or Ctrl+D to exit.\n\n"
  end

  def farewell
    puts "\nSee you next time. ❄️"
  end

  def prompt
    if @history.empty?
      "→ "
    else
      "… "
    end
  end

  def process_input(input)
    @history << { role: "user", content: input }
    @context += "#{input}\n"

    print "Thinking… "

    # Simulate LLM response streaming (replace with real LLM call)
    response = generate_response(input)

    # Stream it character-by-character
    stream_response(response)

    @history << { role: "assistant", content: response }
    @context += "#{response}\n\n"
  end

  # Replace this with real LLM call (Claude, Grok API, etc.)
  def generate_response(prompt)
    # For demo purposes — real version would stream tokens
    sleep 0.4

    <<~RESPONSE
      Here's a quick answer:

      Yes — CLIs can learn a lot from conversational UIs like Grok.

      The best traits to steal are:
      • streaming output → feels alive
      • minimal friction → no mandatory flags for common cases
      • context memory → remembers what was just said
      • calm & confident tone → no shouting, no emoji spam
      • graceful failure → tells you what to try next

      Want a real example with streaming and context?
      Just say the word.
    RESPONSE
  end

  def stream_response(text)
    print "\r" + " " * 20 + "\r"  # clear "Thinking…" line

    text.each_char do |char|
      print char
      $stdout.flush
      sleep(rand(0.015..0.045))  # human-like typing speed
    end

    puts "\n\n"

rescue => e
  puts "\nSomething went sideways: #{e.message}"
  puts "Try again or type 'help' for ideas."
end
How to run it
Bashchmod +x master-cli.rb
./master-cli.rb
# or
ruby master-cli.rb "tell me a grok-inspired cli principle"
What makes this Grok-inspired

No ceremony — just start typing
Streaming feel — characters appear gradually
Quiet thinking indicator — only shows briefly
Subtle continuation prompt — → first, then … 
Natural exit — Ctrl+D or empty line
Context is remembered — you can ask follow-up questions
Calm error handling — non-punishing
Very few dependencies — only standard library (can add tty-prompt later if wanted)

Next-level improvements you can add

Real LLM streaming
Replace generate_response with a streaming API call (e.g. Anthropic's streaming response):Rubydef generate_response(prompt)
  # Pseudo-code — use anthropic-sdk-ruby or similar
  response = ""
  client.messages.create(
    model: "claude-3-5-sonnet-20241022",
    messages: [{ role: "user", content: prompt }],
    stream: true
  ) do |chunk|
    content = chunk.dig("delta", "text") || ""
    response += content
    print content
    $stdout.flush
  end
  response
end
Persistent context
Save/load @context and @history to ~/.master/context.json
Command recognition
Add simple prefix commands:Rubyif input.start_with?("!")
  handle_command(input[1..])
end
Very subtle progress
Replace "Thinking…" with braille spinner:Rubyspinner = %w[⠋ ⠙ ⠹ ⠸ ⠼ ⠴ ⠦ ⠧ ⠇ ⠏]
# in a thread or non-blocking way

Would you like me to extend this example with:

real LLM streaming integration?
persistent conversation history?
a few built-in commands (!clear, !history, !help)?
a very minimal tty-prompt menu as fallback?
or something else?

Just tell me which direction feels most useful right now.1 / 2Integrate tty-prompt featuresYes, let's make the CLI feel even more polished and interactive — while staying Grok-inspired (low noise, helpful, fast, personality in text not in UI chrome).
tty-prompt is excellent for this: it gives clean, modern terminal menus, input validation, auto-completion, spinners, etc. without turning the CLI into a full TUI monster.
Goals for this integration

Keep the core loop simple and streamy
Add guided interaction only when needed (ambiguous input, choices, confirmation)
Use subtle spinners / progress during thinking
Maintain personality in messages
Stay minimal dependencies — only tty-prompt, tty-spinner, tty-markdown (optional)

    <<~ANSWER
      Yes — tty-prompt makes CLIs feel modern without becoming heavy.

      It adds:
      • clean single/multiple choice menus
      • auto-completion & filtering
      • spinners & progress bars
      • password / editor inputs
      • pretty tables & markdown rendering

      Example: instead of raw gets, you get:

      → What do you want to do?
        • Refactor code
        • Ask question
        • Clear history

Just say which one you want to see next. 😊Explain tty-prompt advanced featuresHere’s a clear overview of advanced features in tty-prompt (the most popular Ruby gem for building beautiful, interactive CLI prompts). These go beyond basic ask, yes?, and select, and are especially useful when you want your CLI to feel polished, intuitive, and powerful without becoming a full-blown TUI.
1. Custom Filters & Auto-Completion (filter, enum, path)
Ruby# Filterable list with fuzzy search (very Grok-like discoverability)
@prompt.select("Choose a city", %w[Oslo Bergen Trondheim Tromsø Stavanger], filter: true)

# Enum style (accepts only predefined values, auto-completes)
@prompt.enum_select("Preferred editor?", %w[vim nano helix micro], default: 3)

# Path auto-completion (great for file/directory picker)
@prompt.ask("Select config file:", path: true) do |q|
  q.file? true           # only files
  q.dir?  false
  q.glob  "*.yml,*.yaml" # filter by extension
end
2. Multi-select with markers & pagination
Ruby# Beautiful multi-choice with shift+space, pagination on long lists
choices = %w[apple banana cherry date elderberry fig grape honeydew]
selected = @prompt.multi_select("Pick your fruits", choices,
  per_page: 6,
  cycle: true,
  symbols: { marker: "✔", cross: "✘" },
  default: [1, 3]
)

# You can also pre-mark some
@prompt.multi_select("Select tags", %w[ruby rails htmx tailwind], active_color: :cyan)
3. Expand (git-style choice menu)
Ruby# Classic git-style "expand" prompt (very compact + mnemonic)
choice = @prompt.expand("File exists. Overwrite?", [
  { key: "y", name: "overwrite", value: :yes },
  { key: "n", name: "skip",      value: :no },
  { key: "a", name: "all",       value: :all },
  { key: "q", name: "quit",      value: :quit, default: true }
])

# Prints:
# File exists. Overwrite? [(Y)es, (n)o, (a)ll, (q)uit]
4. Editor / multi-line input with syntax highlighting
Ruby# Opens $EDITOR (vim, nano, helix, etc.) for longer input
long_text = @prompt.editor("Write your commit message:",
  default: "fix: streaming response bug",
  syntax:  :markdown,          # or :ruby, :yaml, etc.
  word_wrap: 72
)
5. Masked / password input with echo toggle
Ruby# Secure input with optional reveal (press Ctrl+R to toggle echo)
secret = @prompt.mask("API key:", required: true, echo: false)

# Or with confirmation
password = @prompt.mask("Password:", required: true) do |q|
  q.confirm true
  q.messages[:confirm] = "Confirm password:"
end
6. Slider (number range picker)
Ruby# Nice visual slider for numeric input
temperature = @prompt.slider("Temperature", min: 0.0, max: 2.0, step: 0.1,
  default: 0.7,
  format: "|:slider| %.1f",
  active_color: :blue
)
7. Table & list rendering (with tty-table integration)
Rubyrequire 'tty-table'

data = [
  ["Oslo",     "-4 °C", "snow"],
  ["Bergen",   "+2 °C", "rain"],
  ["Trondheim", "-7 °C", "clear"]
]

@prompt.say(TTY::Table.new(["City", "Temp", "Weather"], data).render(:unicode, resize: true))
8. Progress & spinners (tty-spinner integration)
Rubyspinner = TTY::Spinner.new("[:spinner] Generating… ", format: :dots_8, success_mark: "✓")
spinner.auto_spin

# ... long operation ...

spinner.success("Done in 3.2s")
9. Advanced validation & conversion
Rubyage = @prompt.ask("Your age?", convert: :int) do |q|
  q.in "18..120"
  q.messages[:range?] = "%{value} is not between %{in}"
  q.modify :strip, :downcase  # can chain modifiers
end

email = @prompt.ask("Email?") do |q|
  q.validate(/\A[^@\s]+@[^@\s]+\z/)
  q.messages[:valid?] = "That's not a valid email"
end
10. Custom themes & colors
Ruby@prompt = TTY::Prompt.new(
  track_history: false,
  active_color: :bright_cyan,
  symbols: { marker: "❯", radio_on: "◉", radio_off: "○" }
)

The gem ships with many ready-to-use named formats. Here are the most common and visually appealing ones (from docs and source):

How to use a specific format
Rubyrequire 'tty-spinner'

# Classic rotating bar
spinner = TTY::Spinner.new("[:spinner] Loading…", format: :classic)
spinner.auto_spin   # starts animation in background thread

# Do work...
sleep 3

spinner.success("Loaded!")  # or .error("Failed!")

# Braille dots (very smooth on modern terminals)
spinner = TTY::Spinner.new("[:spinner] Processing…", format: :dots_8)
Custom Formats (most advanced part)
You can define your own animation sequence completely:
Ruby# Custom heartbeat style
custom_format = {
  interval: 6,                    # speed (lower = faster)
  frames:   %w[♥ ♡ ♥ ♡ ♥]        # any unicode chars
}

spinner = TTY::Spinner.new("[:spinner] Heartbeat…", **custom_format)
spinner.auto_spin
sleep 5
spinner.success
Or even more advanced (with success / error marks):
Rubyspinner = TTY::Spinner.new(
  "[:spinner] Building…",
  format: :dots_9,
  success_mark: "✔",
  error_mark:   "✘",
  hide_cursor:  true
)
Multi-Spinner (parallel tasks)
For showing multiple concurrent spinners (very useful for parallel downloads / jobs):
Rubymulti = TTY::Spinner::Multi.new("[:spinner] Overall…", format: :dots_8)

sp1 = multi.register("[:spinner] Task 1…", format: :spin)
sp2 = multi.register("[:spinner] Task 2…", format: :dots_11)

sp1.auto_spin
sp2.auto_spin

# ... do work ...

sp1.success
sp2.error
multi.success("All done!")
Tips & Best Practices (2026 style)

Use :dots_8 or :dots_9 as default — looks modern, smooth on most terminals.
Always set hide_cursor: true — cleaner look.
Use interval lower than 10 for faster feel (e.g. 6–8).
Combine with TTY::ProgressBar for known-length tasks (hybrid spinner + bar).
For very long tasks, add message updates: spinner.update(title: "Uploading 45%").
In non-interactive terminals (CI, pipes) → auto fallback to silent mode via TTY::Spinner::Multi.top_level.auto_debrief = false.

Would you like a small demo script that shows several formats side-by-side, or integration of a multi-spinner into your earlier CLI example?50 sourcesDemo script for multiple formats
Integrate with TTY::ProgressBar and other top goodiesHere is a self-contained, runnable Ruby demo script that showcases multiple tty-spinner formats side-by-side (in a clean layout), integrates TTY::ProgressBar for known-length tasks, and throws in a few other top goodies from the tty family:

tty-spinner (multiple formats + custom)
tty-progressbar (smooth progress + custom format)
tty-spinner + tty-progressbar hybrid (spinner during unknown phase → bar during known phase)
tty-table (pretty output of results)
tty-prompt (simple user choice to select which demo to run)

What you’ll see

Clean menu via tty-prompt
Side-by-side spinner format comparison
Two different progress bar styles
Spinner → bar transition (realistic for unknown → known work)
Pretty unicode table summary
Pastel coloring for subtle visual pop
Pause between demos so you can read

Want to add:

real LLM streaming inside one of the demos?
multi-spinner example (parallel fake tasks)?
custom spinner + progress bar combo with dynamic title updates?

Just say the word! 😄Add LLM streaming exampleHere’s a clean, self-contained Ruby CLI example that integrates real LLM streaming using the Anthropic SDK (Claude models) with:

tty-prompt for input/menu
tty-spinner for thinking phase
character-by-character streaming output (Grok-like typing feel)
context memory (simple in-session history)

What happens when you run it

Clean welcome message
Simple →  prompt (tty-prompt)
You type e.g. "best Norwegian winter hikes"
Subtle braille spinner appears (dots_9 format — very smooth)
Claude response streams in character-by-character (feels alive, low latency)
Conversation context is preserved → follow-up questions work naturally
Ctrl+C or empty line exits gracefully

Quick customizations you can do

Change model: "claude-4-opus-20250219" or "claude-3-opus-20240229" when available
Add temperature slider (from tty-prompt advanced):

Rubytemp = PROMPT.slider("Temperature", min: 0.0, max: 1.5, step: 0.1, default: 0.7)
# then pass temperature: temp

Add spinner during connection setup:

Ruby@spinner.update(title: "Connecting to Claude…")

Save/load history to ~/.master/history.json for persistence:

Ruby# At end of run
File.write("~/.master/history.json", @history.to_json)
Want to add:

a menu to choose model / temperature / clear history?
multi-line editor input for complex prompts?
real-time token counter / cost estimate?
x_keyword_search integration as a built-in command?

Just tell me what you'd like next! 😄Add multi-line input editorHere’s your updated CLI with multi-line input editor support using tty-prompt's editor feature.
This gives users a real editor (vim, nano, helix, etc. — whatever is set in $EDITOR) for longer/complex prompts, while keeping the streaming response and Grok-like feel intact.

How it works now

Welcome screen explains the two input modes
Menu choice (quick or editor) — clean tty-prompt select
Quick mode → single-line ask (as before)
Editor mode → opens your $EDITOR (vim/nano/helix/zed/etc.) with a markdown-friendly starting comment
Write as long/complex as you want
Save & exit → prompt is sent

Streaming response remains character-by-character
Context preserved across turns

Example session flow
textMASTER — powered by Claude. Ask anything.
Type short prompt or press Enter → choose 'Editor' for multi-line.
Empty line or Ctrl+C to exit.

How do you want to input?
→ Quick one-liner
  Multi-line editor
  Exit

→ Quick one-liner
→ what's the best winter hike near Oslo?
[spinner] → Thinking…
Rondane or Gaustatoppen are classics, but closest serious winter option from Oslo is probably…
[streams character by character]

… next prompt → chooses Editor → opens vim/nano → writes 10-line detailed question → saves → streams long answer
Optional tweaks you can add right away

Default to editor if previous input was long

Rubydef gather_input
  last_was_long = @history.last && @history.last[:content]&.length.to_i > 150
  default_choice = last_was_long ? :editor : :quick
  # then use default: default_choice in select
end

Syntax highlighting in editor

Rubysyntax: last_was_code? ? :ruby : :markdown

Auto-detect code block in editor input

Rubyinput = editor_result
if input =~ /^```ruby\s*\n(.*?)```/m
  # treat as code → maybe run or format differently
end
Would you like:

persistent history (save/load from file)
model/temperature choice menu
built-in command prefix (!clear, !model claude-4, !editor)
auto-detection of code vs prose prompts
or something else?

Just tell me which feels most useful next! 😊Explain TTY::Prompt editor optionsTTY::Prompt's editor method is one of its most powerful advanced features. It lets users edit multi-line text in their preferred $EDITOR (vim, nano, helix, zed, vscode — whatever is set in the environment), then returns the saved content back to your Ruby program.
This is perfect for:

long prompts / queries
commit messages
writing code snippets
editing YAML/JSON configs
creating detailed descriptions

Basic usage
Rubytext = PROMPT.editor("Your message:")
puts "You wrote:\n#{text}"
When called, it:

Opens the user's $EDITOR with a temporary file
Pre-fills with optional default text
User edits and saves/exits
Returns the full file content as a string (or nil if canceled)

All available options (2025–2026 tty-prompt version)

Practical examples

Markdown-friendly long prompt with syntax

Rubyprompt_text = PROMPT.editor("Detailed question or story:",
  default: "# Title\n\nWrite your full question here.\nUse markdown if you want.",
  syntax: :markdown,
  word_wrap: 72,
  required: true
)

Ruby code snippet input

Rubycode = PROMPT.editor("Paste or write Ruby code:",
  syntax: :ruby,
  extension: ".rb",
  default: "def hello\n  puts 'world'\nend",
  required: true
)

Commit message style (git-like)

Rubycommit_msg = PROMPT.editor("Commit message:",
  default: "fix: streaming delay in CLI\n\n- Fixed char-by-char timing\n- Added spinner",
  syntax: :text,
  word_wrap: 72,
  editor: "nano"   # force nano if you hate vim
)

With validation

Rubyemail_body = PROMPT.editor("Email body:", required: true) do |q|
  q.validate ->(text) { text.length > 20 }, "Message too short!"
  q.messages[:validate?] = "Please write at least 20 characters."
end

Custom editor + env vars

Rubylong_input = PROMPT.editor("Config override:",
  editor: "helix",
  env: { "HELIX_THEME" => "nord" }
)
Important notes

If $EDITOR is unset → falls back to vi or nano (tty-prompt default behavior)
Temporary file is automatically cleaned up after reading
editor returns nil if user cancels (Ctrl+C / :q! without save)
Works beautifully with markdown syntaxes because many editors (helix, zed, vscode) highlight it automatically
For very large input → consider word_wrap: nil to avoid line wrapping confusion

Summary: when to use editor
Use editor whenever:

Input > ~100–150 chars
User might want syntax highlighting
Formatting matters (lists, code, markdown)
You want zero friction for power users

Use regular ask or multiline for everything else.
Would you like:

a demo script that combines editor + streaming response?
