# Rollup
Rollup aggregates the contents of text-based files and webpages into a markdown file.
## Features
- File type filtering for targeted content aggregation
- Ignore patterns for excluding specific files or directories
- Support for code-generated file detection and exclusion
- Advanced web scraping functionality with depth control
- Verbose logging option for detailed operation insights
- Exclusionary CSS selectors for precise web content extraction
- Support for multiple URLs in web scraping operations
- Configurable output format for web scraping (single file or separate files)
- Flexible configuration file support (YAML)
- Automatic generation of default configuration file
- Custom output file naming
- Concurrent processing for improved performance
## Installation
To install Rollup, make sure you have Go installed on your system, then run:
```bash
go get github.com/tnypxl/rollup
```
## Usage
Basic usage:
```bash
rollup [command] [flags]
```
### Commands
- `rollup files`: Rollup files into a single Markdown file
- `rollup web`: Scrape main content from webpages and convert to Markdown
- `rollup generate`: Generate a rollup.yml config file
### Flags for `files` command
- `--path, -p`: Path to the project directory (default: current directory)
- `--types, -t`: Comma-separated list of file extensions to include (default: .go,.md,.txt)
- `--codegen, -g`: Comma-separated list of glob patterns for code-generated files
- `--ignore, -i`: Comma-separated list of glob patterns for files to ignore
- `--output, -o`: Name of the output file (default: rollup_output.md)
- `--concurrent, -c`: Number of concurrent goroutines for processing (default: 4)
### Flags for `web` command
- `--urls, -u`: URLs of the webpages to scrape (comma-separated)
- `--output, -o`: Output type: 'single' for one file, 'separate' for multiple files (default: single)
- `--depth, -d`: Depth of link traversal (default: 0, only scrape the given URLs)
- `--css`: CSS selector to extract specific content
- `--exclude`: CSS selectors to exclude from the extracted content (comma-separated)
- `--concurrent, -c`: Number of concurrent goroutines for processing (default: 4)
### Global flags
- `--config, -f`: Path to the configuration file (default: rollup.yml in the current directory)
- `--verbose, -v`: Enable verbose logging
- `--timeout, -t`: Timeout for web requests in seconds (default: 30)
## Configuration
Rollup can be configured using a YAML file. By default, it looks for `rollup.yml` in the current directory. You can specify a different configuration file using the `--config` flag.
Example `rollup.yml`:
```yaml
file_types:
- go
- md
ignore:
- node_modules/**
- vendor/**
- .git/**
code_generated:
- **/generated/**
scrape:
urls:
- url: https://example.com
css_locator: .content
exclude_selectors:
- .ads
- .navigation
output_alias: example
output_type: single
```
## Examples
1. Rollup files with default configuration:
```bash
rollup files
```
2. Web scraping with multiple URLs and increased concurrency:
```bash
rollup web --urls=https://example.com,https://another-example.com --concurrent=8
```
3. Generate a default configuration file:
```bash
rollup generate
```
4. Use a custom configuration file and specify output:
```bash
rollup files --config=my-config.yml --output=project_summary.md
```
5. Web scraping with separate output files and custom timeout:
```bash
rollup web --urls=https://example.com,https://another-example.com --output=separate --timeout=60
```
6. Rollup files with specific types and ignore patterns:
```bash
rollup files --types=.go,.md --ignore=vendor/**,*_test.go
```
7. Web scraping with depth and CSS selector:
```bash
rollup web --urls=https://example.com --depth=2 --css=.main-content
```
