.V Estensione file

Developer file used by Coq, an application used to develop mathematical proofs; saved in a text format and contains source code constructed in the Gallina language, which is based on an expressive formal language called Calculus of Inductive Constructions (CIC); used for storing mathematical proofs.

Developers specify expressions in V files using the Gallina "vernacular," which is the syntax, or language of commands, for the Gallina language. Once V files are written, they can be compiled and run with the Coq Proof Assistant IDE, which has the program name CoqIDE.

NOTA: Development for Coq, which was previously maintained by The Coq Development Team, is now maintained by ADT Coq. ADT stands for "Action for Technological Development."

A V file contains source code written in the V programming language. Typically, a V file contains a V program or module.

You can open a V file and edit its contents using any text or source code editor. Source code editors, such as Microsoft Visual Studio Code and GitHub Atom, contain helpful tools that make reading and editing V files easier.

If your V file contains a program, you can run the program using V's run command.

Raw "V" image file created by ppmtoyuvsplit, a Unix-based program used to split Portable PixMap images (.PPM files) into .Y, .U, and V files; stores the "V" chrominance, or color, component for the image; may be restored back to the original PPM file using the yuvsplittoppm utility.

V files store image data in a format required by the Stanford MPEG codec.

NOTA: The yuvsplittoppm and ppmtoyuvsplit command-line utilities are part of the netpbm Unix-based graphics package.
