Haskell vs. PureScript vs. jPDFWeb vs. python-sql Comparison Chart

Every expression in Haskell has a type that is determined at compile time. All the types composed together by function application have to match up. If they don't, the program will be rejected by the compiler. Types become not only a form of guarantee, but a language for expressing the construction of programs. Every function in Haskell is a function in the mathematical sense (i.e., "pure"). Even side-effecting IO operations are but a description of what to do, produced by pure code. There are no statements or instructions, only expressions that cannot mutate variables (local or global) nor access state like time or random numbers. You don't have to explicitly write out every type in a Haskell program. Types will be inferred by unifying every type bidirectionally. However, you can write out types if you choose, or ask the compiler to write them for you for handy documentation.

jPDFWeb is a Java library to convert PDF documents to SVG / HTML5. The library can save to the local file system or to an output stream to be able to serve the document directly to a client browser when working within a J2EE server. jPDFWeb is built on top of Qoppa’s proprietary PDF technology so you do not have to install any third party software or drivers. Since it is written in Java, it allows your application to remain platform independent and run on Windows, Linux, Unix (Solaris, HP UX, IBM AIX), Mac OS X and any other platform that supports the Java run-time environment. Features: -Convert PDF Documents to HTML5 / SVG -Convert Microsoft Word & Excel Documents to HTML5 (when combined with jOfficeConvert) -Convert Text -Convert Images -Convert Vector Graphics -Convert Annotations, Links and Form Field Data -Convert Digital Signature Validation Status -Export Page Thumbnails -Support for CJK fonts -Support for latest PDF format
