README.md

Purpose: tests data for the output of V's C code generator

TLDR: v run vlib/v/gen/c/coutput_test.v

coutput_test.v is a test runner, that checks whether the generated C source code matches all expectations, specified in *.c.must_have files, in the folder vlib/v/gen/c/testdata/ .

Each .c.must_have file, has to have a corresponding .vv file.

Each .c.must_have file, consists of multiple lines. Each of these lines, should be present at least once in the output, when the .vv file is compiled with -o - .

Note: this test runner can also be used to verify and keep from regressing partial fixes to V's checker, i.e. ones that make a program type check fine, but that still lead to codegen problems. To do that, put the V code that the checker can typecheck in a .vv file in this folder, then create a corresponding .c.must_have file in this folder too. It should have a single line in it: // THE END. . The V codegen will end every source that it generates with that line, so its presence, effectively guarantees that cgen succeeded/ended, even if the produced C code can not be compiled yet.
