scratch

Scratch is a highly efficient Vim plugin that has been designed to offer an incredibly Emacs-like scratch buffer. It provides the flexibility to write and evaluate anything in the buffer as Vim script. As a temporary buffer, it is not linked to any real file, which means there will be no remnants of the content of the buffer after you quit Vim.

The Scratch buffer is highly essential for testing out little bits of script or code. It is also highly effective for quick jotting of notes and ideas. With Scratch, you can evaluate code in the buffer and get immediate feedback.

Vim, on the other hand, is a highly stable text editor initially released by Bram Moolenaar in 1991, with many additional features designed to make editing program source code more manageable. Its comprehensive scope offers various tools that make programming easy.

Vim is designed to be highly versatile and crosses multiple platforms. It is most popularly used with Unix-like operating systems. As free and open-source software, Vim's compatibility with the GNU General Public License offers programmers the freedom to tweak the code as they deem fit. Vim's license also includes charityware clauses that require users to donate to charity when they purchase a license.

Overall, Scratch is an excellent Vim plugin that every programmer should consider integrating into their toolbox. Its use with Vim, the industry-standard text editor, makes it an ideal development tool for all programmers.
