+# IntelliJ IDEA setup on Windows for Plutus

+
+### My review
+I have been trying to figure out an optimal IDE setup for working with Plutus smart contracts. I have come to like the following setup on Windows, using the IntelliJ IDE, its HaskForce plugin and Cygwin. All in all, a fairly good IDE experience. 
+
+There are some trade-offs, which you can assess from the pros and cons given below.
+
+**Pros**: 
+   - Does not need WSL on Windows (WSL is still needed if you want to launch plutus playground due to its dependency on nix-shell) 
+   - Haskell syntax highlighting
+   - View and navigate to function definitions
+   - One IDE experience if you work on IntelliJ for other projects
+
+**Cons**:
+   - Code completion is limited to the same file. _(Maybe there is a workaround for this.)_
+   - Certain sections of code causes navigation not work for all code after it in the file. eg: Saw this happen in Value.hs 
+
+
+### Setup steps
+1. Install ghc 8.10.4 from [here](https://www.haskell.org/ghc/download_ghc_8_10_4.html#windows64)
+
+  _Skip your OS drive if you want to space there_
+
+
+2. Install [cabal](https://www.haskell.org/cabal/download.html).
+
+   _Skip your OS drive if you want to space there_
+
+
+3. Add cabal and ghc to path (system variables).
+   Go to `Control Panel -> System -> Advanced system settings -> Environment Variables -> Edit` to do that.
+
+
+4. Install **IntelliJ IDEA** in case you do not have it already, from [here](https://www.jetbrains.com/idea/download/#section=windows)
+   Community edition should work fine.
+
+
+5. Install **Cygwin**.
+
+   Cygwin is needed since without a unix like environment, running `cabal repl` will throw error:
+
+   ```shell
+    ...cabal.exe: The package has a ‘./configure’ script. This requires a Unix compatibility toolchain such as MinGW+MSYS or Cygwin.
+   ``` 
+   You just need to install CygWin and then make sure the binaries are in your path. If you install cygwin to `c:\cygwin` then the binaries are in `c:\cygwin\bin`. To add `c:\cygwin\bin` to your path temporarily you can use a command prompt and do set `path=%path%;c:\cygwin\bin`. 
+      Or you can add to the path permanently like in step #3.
+
+
+6. Two ways to launch the cygwin terminal.
+
+   a. Run the commands below on the usual IntelliJ terminal.
+
+   b. Better way:
+   Add the line below line to
+        `Settings(Ctrl+Alt+S) -> Tools -> Teminal -> shell path`, so that you get the cygwin shell by default when you start a terminal in IntelliJ
+
+   _Note: Copy as is keeping the quotes_
+
+      ``` shell
+      "{path to your cygwin}\bin\bash" -c "exec /usr/bin/env INTELLIJ=true $SHELL --login -i"
+   ```
+   Upon launch of terminal use this command to switch the project directory
+
+   ``` shell
+   ${INTELLIJ-false} && cd ${OLDPWD-.}
+   ```
+7. Check out plutus project from SVN or load from disk.
+
+If your project is built using cabal
+8. Run cabal repl on the cygwin terminal opened in step 6.
+
+9. After dependencies are downloaded run module discovery from `Tools | Discover Cabal Packages`
+
+
+Cheers!
