Is there a PDF generation library similar to http://prawnpdf.org/

Question

I am looking for the ability to generate PDFs in a similar manner to Prawnpdf using Crystal language. Is there such a library, or is there a way for me to call into ruby code (like a ruby binding)?

Answer 1

There is actually NO pdf generation library for Crystal..

But if you have the time, there are libraries which has a C/C++ interface that you could use to create a pdf generation lib :

• JagToPdf : Exemple in C (Full user guide here)
• libHaru : It is written entirely in C, so interfacing with Crystal should not be difficult. Exemple Usage here
