# Autocomplete Feature

## Overview

QLPyCon includes intelligent autocomplete for console variables (cvars) and commands with fuzzy matching support.

## Features

- **Real-time Suggestions**: Fuzzy matches appear below the input line as you type
- **Tab Cycling**: Press Tab to cycle through suggestions
- **Smart Argument Highlighting**: Current argument position highlighted in reverse video
- **Argument Value Suggestions**: Intelligent suggestions for command arguments (bot names, maps, gametypes, etc.)
- **Command Signatures**: Automatic display when typing commands with arguments
- **Fuzzy Matching**: Finds matches even with partial or misspelled input
- **Smart Scoring**: Best matches appear first (exact > prefix > substring > fuzzy)

## Usage

Type a partial command (2+ characters) and fuzzy matches appear below the prompt:

```
$ sv_m
sv_maxclients sv_minrate sv_maxrate sv_timeout sv_floodprotect
```

Press **Tab** to cycle through the suggestions:
```
$ sv_m          [Tab]  →  sv_maxclients
$ sv_maxclients [Tab]  →  sv_minrate
$ sv_minrate    [Tab]  →  sv_maxrate
$ sv_maxrate    [Tab]  →  sv_timeout
$ sv_timeout    [Tab]  →  sv_floodprotect
$ sv_floodprotect [Tab]  →  sv_maxclients  (cycles back)
```

**Command signatures with argument highlighting:**

When you type a command that has arguments, the signature appears automatically with the **current argument highlighted**:

```
$ addbot
[<botname>] [skill 1-5] [team] [msec delay] [altname]
     ↑ highlighted (currently typing this)

$ addbot sarge
<botname> [[skill 1-5]] [team] [msec delay] [altname]
              ↑ highlighted (now typing skill level)

$ addbot sarge 5
<botname> [skill 1-5] [[team]] [msec delay] [altname]
                         ↑ highlighted (now typing team)

$ kick
[<player>]
    ↑ highlighted

$ g_gametype
[<0=FFA 1=Duel 2=TDM 3=CA 4=CTF...>]
              ↑ highlighted
```

The highlighted argument (shown with `[[ ]]` above, displayed in reverse video) shows you **exactly what to type next**.

Matches update in real-time as you type or delete characters.

**Argument value suggestions:**

After typing a command with a space, the system suggests valid values for each argument with fuzzy matching:

```
$ addbot
Anarki Angel Biker Bitterman Bones
  ↑ Shows bot names

$ addbot sar
Sarge
  ↑ Fuzzy matches 'sar' → 'Sarge'

$ addbot Sarge
1 2 3 4 5
  ↑ Shows skill levels (1-5)

$ addbot Sarge 4
red blue free spectator any
  ↑ Shows team values

$ map
aerowalk almostlost arenagate asylum battleforged
  ↑ Shows map names

$ map blood
bloodrun
  ↑ Fuzzy matches 'blood' → 'bloodrun'

$ g_gametype
0 1 2 3 4 FFA Duel TDM CA CTF
  ↑ Shows numeric and string gametype values

$ callvote
map kick shuffle teamsize
  ↑ Shows vote types
```

The system knows valid values for **25+ commands** including:
- **32 bot names**: Sarge, Ranger, Visor, Xaero, Anarki, etc.
- **40+ maps**: bloodrun, campgrounds, toxicity, aerowalk, etc.
- **12 game types**: FFA, Duel, TDM, CA, CTF, etc. (numeric and string forms)
- **Vote types**: map, kick, shuffle, teamsize, g_gametype, etc.
- **Team values**: red, blue, free, spectator, any
- **Skill levels**: 1-5 for bots
- **Boolean values**: 0, 1, true, false, enabled, disabled
- **Common settings**: timelimits, fraglimits, sv_fps values, etc.

Arguments with freetext (like player names or custom messages) fall back to showing the signature with highlighting.

## Supported Commands

**76 cvars and commands included:**

### Commands with Signatures

The following commands show usage help when selected:

- `ban` - <player>
- `tempban` - <player> <seconds>
- `tell` - <player> <message>

**Game settings:**

- `timelimit` - <minutes>
- `fraglimit` - <frags>
- `capturelimit` - <captures>

**Map & voting:**
- `map` - <mapname>
- `callvote` - <vote type> [args...]

### Additional Cvars

**Server Configuration:**
- sv_hostname, sv_maxclients, sv_fps, sv_pure, etc.

**Network & ZMQ:**
- net_port, zmq_rcon_enable, zmq_stats_enable, etc.

**QLX (minqlx):**

## Technical Details

### Fuzzy Matching Algorithm

Scoring system (higher = better match):
- **1000**: Exact match
- **500+**: Prefix match (prioritizes shorter results)
- **100-**: Substring match (earlier = better)
- **50**: Contains all characters in order

### Examples:

```python
autocomplete('sv_')
→ ['sv_fps', 'sv_pure', 'sv_maxrate', 'sv_minrate', 'sv_timeout']

autocomplete('time')
→ ['timelimit', 'sv_timeout']

autocomplete('stat')
→ ['status', 'zmq_stats_enable', 'zmq_stats_ip', 'zmq_stats_password', 'zmq_stats_port']
```

## Customization

### Add Your Own Cvars

Edit `cvars.py` and add to the appropriate list:

```python
# Custom cvars
CUSTOM_CVARS = [
    'my_custom_cvar',
    'another_cvar',
]

# Add to ALL_CVARS
ALL_CVARS = (
    SERVER_CVARS +
    GAME_CVARS +
    # ...
    CUSTOM_CVARS
)
```

### Adjust Behavior

In `ui.py`, modify:

```python
# Minimum characters before showing suggestions
if len(current_word) >= 2:  # Change to 1 or 3

# Maximum suggestions displayed
suggestions = autocomplete(current_word, max_results=5)  # Change limit
```

## Keyboard Shortcuts

| Key | Action |
|-----|--------|
| **Tab** | Cycle through autocomplete suggestions |
| **↑** | Previous command in history |
| **↓** | Next command in history |
| **←/→** | Move cursor |
| **Backspace** | Delete (updates suggestions) |
| **Enter** | Send command |

## Notes

- Autocomplete starts after typing 2+ characters
- Suggestions appear on the line below the prompt
- Up to 5 matches shown at once (best matches first)
- Suggestions update in real-time as you type
- History navigation (↑/↓) works normally

## Testing Autocomplete

```bash
# Run cvars module directly to test matching
python3 cvars.py

# Output shows test queries and results
```
