## Creating the repository and project
Create the repository as normal: create the project in Gitolite, clone it, and insert the `.gitignore` and `README.md` files.
-Within the project directory, there will be one package for each day. This will save time waiting for `stack` to check every executable before compiling what's changed. Each package needs a separate directory tree and a separate `.cabal` file.
+There's just one package, with the code in sub-directories of the `src` directory. Each day will generate one (or more) entries in the `adventofcode17.cabal` file.
-## Creating the first package
-Then create the basic `stack` project with it. This will create a new directory. Note that this new directory name can't have a hyphen-delimited word that's just digits, so the initial project will have to be `adventofcode1701`
+Create the basic `stack` project. This will create a new directory. Note that this new directory name can't have a hyphen-delimited word that's just digits, so the project will have to be `advent-of-code`
```
-stack new adventofcode1701 simple
+stack new advent-of-code --bare simple
```
-This project will be demoted to being a package, but one that will hold the overall project.
+Modify the `stack.yaml` file as needed, such as adding the `ghc-options` stanza.
-Then create the top-level `stack.yaml` file to hold the overall project information.
+## Creating subsequent days
-```
-stack init
-```
-
-Modify this top-level `stack.yaml` file as needed, such as adding the `ghc-options` stanza. You can then delete `adventofcode1701/stack.yaml`.
-
-## Creating subsequent packages
-
-Each package needs a separate directory tree and a separate `.cabal` file.
-
-To work on a project, `cd` into that project's directory.
+Each day lives in a separate directory within the `src` directory. It will also need it's own stanza in `advent-of-code.cabal`.
Compile with
```
```
or
```
-stack build adventofcode1701
+stack build advent01
```
Run with
Run interactively with
```
-stack ghci adventofcode1701:exe:advent01
+stack ghci advent-of-code:exe:advent01
```
To profile, use
stack exec -- advent01 +RTS -p -hy
```
+# Packages
+
+Stack is using the [9.14-lts resolver](https://www.stackage.org/lts-9.14) for packages, so make sure you read the [correct documentation for the packages included in it](https://www.stackage.org/lts-9.14/docs).
+
+When you use a new package, use
+
+```
+stack solver
+```
+to see how the `stack.yaml` file needs to change, and
+```
+stack solver --update-yaml
+```
+to implement the changes.
