# sparser

Simple URL extractor from text files. Suckless C tool.

sparser scans files for external URLs and prints them to stdout, one per line. It handles HTML, Markdown, MDX, and plain text. Optionally recurses directories and deduplicates output.

## Usage

```
sparser [-vuR] [path | -]

  -v    verbose (print filenames to stderr)
  -u    deduplicate URLs
  -R    recursive directory scan

  path  file or directory to scan
  -     read from stdin
```

## Examples

```sh
# Extract URLs from a single file
sparser notes.md

# Recursively scan a directory, deduplicate
sparser -uR ~/documents/

# Pipe from stdin
curl -s https://example.com | sparser -
```

## Configuration

Edit `config.h` to adjust file size limits, max URL length, and line buffer size.

## Requirements

A C compiler and POSIX headers.

## Installation

Edit `config.mk` to match your local setup, then:

```sh
make clean install
```
