Running a project folder with several files
Suppose you have a folder with several .v files in it, where one of them
main() function, and the other files have other helper
They may be organized by topic, but still not yet structured enough to be their
own separate reusable modules, and you want to compile them all into one program.
In other languages, you would have to use includes or a build system to enumerate all files, compile them separately to object files, then link them into one final executable.
In V however, you can compile and run the whole folder of .v files together,
v run .. Passing parameters also works, so you can
v run . --yourparam some_other_stuff
The above will first compile your files into a single program (named
after your folder/project), and then it will execute the program with
--yourparam some_other_stuff passed to it as CLI parameters.
Your program can then use the CLI parameters like this:
After a successful run, V will delete the generated executable. If you want to keep it, use
v -keepc run .instead, or just compile manually with
Any V compiler flags should be passed before the
runcommand. Everything after the source file/folder will be passed to the program as is – it will not be processed by V.
