FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package robots-txt-checker
Robots.txt checker
Given a robots.txt file this library will give you a straight forward yes/no as to whether you're allowed to access a given resource with a given user agent.
This library has been built with reference to both Google's robots.txt specification and the draft norobots RFC from 1996(!). As such all the following features are supported:
- Wildcards in paths, including across directory boundaries
- The '$' suffix to anchor a path match to the end of a URL
- Sorting of multiple matching user-agent/path blocks by user-agent length
- Decoding of URL encoded paths, with the exception of forward slashes
- A trailing slash on a path indicating that all files under that directory should match
If you find any bugs with this library please don't hesitate to let me know, either create an issue on GitHub or submit a pull request.
