 20 ## Intellij and Clion
 21 
 22 We can use JetBrains' `IntelliJ` and `Clion` for dev work and
 23 decided to leave some project artifacts in the repo.
 24 
 25 Care must be taken with Intellij and Clion
 26 as these tools do not play well together,
 27 specifically we cannot have `Clion` and `Intellij`
 28 project artifacts rooted under each other or in the same dir.
 29 
 30 ### Intellij
 31 The `intellij` subdir under the root HAT directory
 32 contains the `.idea` project dir and the various `*.iml` files
 33 for each of the various `modules`
 34 (note the use of `Intellji`'s meaning of the word of module here)
 35 
 36 As you will note the `intellij` dir is somewhat self contained.  the various `*.iml`
 37 files refer to the source dirs using relative paths.
 38 
 39 I tend to add `Intellij` modules by hand.  There are gotchas ;)
 40 
 41 As with every intellij project, `.idea/modules.xml` 'points' to the iml files for each module (intellij's notion of module ;) )
 42 ```xml
 43 <!--
 44    └──hat
 45        └── intellij
 46             └── .idea
 47                  └── modules.xml
 48 -->
 49  <modules>
 50       <module fileurl="file://$PROJECT_DIR$/hat.iml"   />
 51       <module fileurl="file://$PROJECT_DIR$/backend_opencl.iml"  />
 52       <!-- yada yada -->
 53  </modules>
 54 
 55 ```
 56 
 57 The various `.iml` files then  have relative paths to their source/resource dirs roots.
 58 
 59 ```xml
 60 <module type="JAVA_MODULE" version="4">
 61   <component name="NewModuleRootManager" inherit-compiler-output="true">
 62     <exclude-output />
 63     <content url="file://$MODULE_DIR$/../../../hat/src/java">
 64       <sourceFolder url="file://$MODULE_DIR$/../../../hat/src/java" isTestSource="false" />
 65     </content>
 66     <orderEntry type="inheritedJdk" />
 67     <orderEntry type="sourceFolder" forTests="false" />
 68     <orderEntry type="module" module-name="hat" />
 69   </component>
 70 </module>
 71 
 72 ```
 73 
 74 Making run configurations available to other developers is probably `a bridge too far`
 75 
 76 But with some careful XML tooling we can make it easier to add 'run configurations'.
 77 
 78 ### How intellij stores run configurations
 79 
 80 I also tend to hand hack run configurations so will leave this here for reference
 81 
 82 ```xml
 83 <component name="RunManager" selected="Application.MandelTest">
 84     <configuration name="Mandel" type="Application"
 85                    factoryName="Application" temporary="true"
 86                    nameIsGenerated="true">
 87       <option name="MAIN_CLASS_NAME" value="mandel.Mandel" />
 88       <module name="mandel" />
 89       <option name="VM_PARAMETERS" value="
 90           --enable-preview
 91           --add-exports=java.base/java.lang.foreign.mapper=ALL-UNNAMED
 92           --patch-module=java.base=$PROJECT_DIR$/out/production/java_base_patch
 93           -Djava.lang.foreign.mapper.debug=true" />
 94       <extension name="coverage">
 95         <pattern>
 96           <option name="PATTERN" value="mandel.*" />
 97           <option name="ENABLED" value="true" />
 98         </pattern>
 99       </extension>
100       <method v="2">
101         <option name="Make" enabled="true" />
102       </method>
103     </configuration>
104     <!-- more configs -->
105 </component>
106 ```
107 
108 ### Clion
109 
110 Thankfully Clion uses cmake, so we get to re-use the CMakeLists.txt in the various backends to build.
111 
112 The intent is that these cmake artifacts can be run standalone (using cmake in the appropriate dir),
113 from within Clion and can be used by maven.  So the CMakeLists.txt files have some extra variables to
114 help us use them in these three modes.
