 # Tikker CLI Tools - Usage Guide
 This guide demonstrates how to use the four main Tikker command-line tools.
 ## Tools Overview
 . **tikker-decoder** - Convert keystroke tokens to readable text
 . **tikker-indexer** - Build word index and analyze frequency
 . **tikker-aggregator** - Generate keystroke statistics
 . **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

 ```
 ### 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

 ```
 Weekly statistics in JSON format:
 ```bash
 tikker-aggregator --weekly --format json --output weekly.json
 ```
 Weekday comparison:
 ```bash
 tikker-aggregator --weekday
 ```
 ### Output Example

 ## 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
