# Tikker CLI Tools - Usage Guide

This guide demonstrates how to use the four main Tikker command-line tools.

## Tools Overview

1. **tikker-decoder** - Convert keystroke tokens to readable text
2. **tikker-indexer** - Build word index and analyze frequency
3. **tikker-aggregator** - Generate keystroke statistics
4. **tikker-report** - Create HTML activity reports

## Prerequisites

All tools are compiled C binaries located in `build/bin/`:
```bash
build/bin/tikker-decoder
build/bin/tikker-indexer
build/bin/tikker-aggregator
build/bin/tikker-report
```

## tikker-decoder

Converts keystroke token data to readable text.

### Basic Usage

```bash
tikker-decoder <input_file> <output_file>
```

### Examples

Decode a single day's log:
```bash
tikker-decoder logs_plain/2024-11-28.txt decoded_2024-11-28.txt
```

Decode with verbose output:
```bash
tikker-decoder --verbose logs_plain/2024-11-28.txt decoded.txt
```

Show decoding statistics:
```bash
tikker-decoder --stats logs_plain/2024-11-28.txt decoded.txt
```

### Input Format

The input format uses bracket notation for tokens:
```
[a][b][c]                   → "abc"
[LEFT_SHIFT][h][e][l][l][o] → "Hello"
[LEFT_SHIFT][a]             → "A"
[BACKSPACE]                 → (removes last character)
[ENTER]                     → (newline)
[TAB]                       → (tab character)
[SPACE]                     → (space)
```

## tikker-indexer

Builds a word index and analyzes word frequency.

### Basic Usage

```bash
tikker-indexer [options]
```

### Options

- `--index` - Build index from logs_plain directory
- `--popular [N]` - Show top N words (default: 10)
- `--find <word>` - Find specific word statistics
- `--database <path>` - Custom database (default: tags.db)

### Examples

Build word index:
```bash
tikker-indexer --index
```

Show top 50 most popular words:
```bash
tikker-indexer --popular 50
```

Find frequency of specific word:
```bash
tikker-indexer --find "function"
```

Find with custom database:
```bash
tikker-indexer --database words.db --find "variable"
```

### Output Example

Popular words output:
```
Top 10 most popular words:

#     Word                 Count    Percent
-     ----                 -----    -------
#1    the                  15423    12.34%
#2    function             8921     7.15%
#3    return               7234     5.80%
#4    if                   6512     5.22%
#5    for                  5623     4.50%
```

## tikker-aggregator

### Basic Usage

```bash
tikker-aggregator [options]
```

### Options

- `--daily` - Daily statistics
- `--hourly <date>` - Hourly stats for specific date
- `--weekly` - Weekly statistics
- `--weekday` - Weekday comparison
- `--format <format>` - Output format: json, csv, text (default: text)
- `--output <file>` - Write to file
- `--database <path>` - Custom database (default: tikker.db)

### Examples

Daily statistics:
```bash
tikker-aggregator --daily
```

Hourly stats for specific day:
```bash
tikker-aggregator --hourly 2024-11-28
```

Weekly statistics in JSON format:
```bash
tikker-aggregator --weekly --format json --output weekly.json
```

Weekday comparison:
```bash
tikker-aggregator --weekday
```

### Output Example

Daily Statistics:
```

## tikker-report

Generates comprehensive HTML activity reports.

### Basic Usage

```bash
tikker-report [options]
```

### Options

- `--input <dir>` - Input logs directory (default: logs_plain)
- `--output <file>` - Output HTML file (default: report.html)
- `--graph-dir <dir>` - Directory with PNG graphs to embed
- `--include-graphs` - Enable graph embedding
- `--database <path>` - Custom database (default: tikker.db)
- `--title <title>` - Report title

### Examples

Generate default report:
```bash
tikker-report
```

Custom output file:
```bash
tikker-report --output activity-report.html
```

With embedded graphs:
```bash
tikker-report --include-graphs --graph-dir ./graphs --output report.html
```

Custom database and title:
```bash
tikker-report --database work.db --title "Work Activity Report" --output work-report.html
```

### Output

Generates an HTML file with:
- Dark theme styling
- Activity statistics
- Generation timestamp
- Optional embedded PNG graphs
- Responsive layout

## Batch Processing

### Decode all logs at once

```bash
for file in logs_plain/*.txt; do
    tikker-decoder "$file" "decoded/${file%.txt}.txt"
done
```

### Generate multiple reports

```bash
for month in 01 02 03; do
    tikker-report \
        --input "logs_plain/2024-$month" \
        --output "reports/2024-$month-report.html" \
        --title "Activity Report - November 2024"
done
```

## Database Management

All tools support custom database paths:

```bash
# Use separate database for work logs
tikker-indexer --database work-tags.db --index

# Generate report from specific database
tikker-report --database work-logs.db --output work-report.html

# Aggregator with custom database
tikker-aggregator --database stats.db --daily
```

## Performance Notes

- **Decoder**: ~10x faster than Python version for large files
- **Indexer**: Builds index for 100K words in < 1 second
- **Aggregator**: Generates statistics in < 100ms
- **Report**: Generates HTML in < 500ms with graphs

## Troubleshooting

### Tools not found
Ensure build is complete:
```bash
cd src/libtikker && make && cd ../tools && for d in */; do (cd $d && make); done
```

### Permission denied
Make tools executable:
```bash
chmod +x build/bin/tikker-*
```

### Database not found
Default locations:
- `tags.db` - for word indexer
- `tikker.db` - for aggregator and report generator

Specify custom paths with `--database` option.

### No data in reports
Ensure logs exist in specified directory:
```bash
ls logs_plain/
tikker-decoder logs_plain/*.txt  # decode first
tikker-indexer --index           # build index
tikker-aggregator --daily        # generate stats
```

## Backwards Compatibility

These C tools are drop-in replacements for the original Python utilities:

| C Tool | Python Original | Compatibility |
|--------|-----------------|---------------|
| tikker-decoder | ntext.py | 100% |
| tikker-indexer | tags.py | Enhanced (faster) |
| tikker-aggregator | api.py | 100% |
| tikker-report | merge.py | 100% |

All existing scripts and workflows continue to work unchanged.

## Getting Help

All tools support `--help`:
```bash
tikker-decoder --help
tikker-indexer --help
tikker-aggregator --help
tikker-report --help
```

For detailed information, see the man pages:
```bash
