Haskell堆栈和版本控制

Question

I'm new to Haskell and Stack. When creating a new project using stack new which files should be checked in to git (or any other VCS)? The whole dir?

Answer 1

You should check in stack.yaml , your-project-name.cabal and Setup.hs , as they are necessary for building your project in a reproducible way. The src , app and test directories should also be committed, as they in principle are where your source code will live (you can of course rearrange the structure of the default project if you wish to do so). On the other hand, you should ignore the .stack-work directory, as it contains the build output and other volatile pieces of data.

Answer 2

You can have a look at the recommended Haskell .gitignore on GitHub:

dist
dist-*
cabal-dev
*.o
*.hi
*.chi
*.chs.h
*.dyn_o
*.dyn_hi
.hpc
.hsenv
.cabal-sandbox/
cabal.sandbox.config
*.prof
*.aux
*.hp
*.eventlog
.stack-work/
cabal.project.local
cabal.project.local~
.HTF/
.ghc.environment.*

If you run the stack new --bare yesod-mysql stack template it includes the following .gitignore :

.stack-work/
yesod-mysql.cabal
