| # Adding a new language |
| |
| * Add a etc/config/language.defaults.properties file |
| * Add a etc/config/language.local.properties file with the first compiler |
| - make sure the path is correct, and during launch of CE (node app.js) check to see if CE agrees with you |
| - test the command line options of the language compilers outside of CE |
| * Add language to lib/languages.js |
| - start with the basics, *class LanguageCompiler extends BaseCompiler* and implement the `OptionsForFilter` method |
| - comment out the line saying `fs.remove(result.dirPath);` in base-compiler.js, so the latest CE compile attempt remains on disk for you to review |
| - remember to undo this change before opening a PR |
| - for reference, the basic behaviour of the BaseCompiler is: |
| - make a random temporary folder |
| - save example.extension to the new folder, the full path to this is the **inputFilename** |
| - the **outputFilename** is determined by the `getOutputFilename()` method |
| - execute the compiler.exe with the arguments from `OptionsForFilter()` and adding **inputFilename** |
| - be aware that the the language class is only instanced once, so storing state is not possible |
| - if the compiler has problems with the defaults, you will have to override the `runCompiler()` method |
| - when overriding `runCompiler()`, here are some ideas: |
| - set **execOptions.customCwd** parameter if the working directory needs to be somewhere else |
| - set **execOptions.env** parameter if the compiler requires special environment variables |
| - manipulate **options**, but make sure the user can still add their own arguments in CE |
| - test with node app.js --debug so you see all execution arguments |
| |
| * Add static/modes/language-mode.js and *require* it in static/panes/editor.js |
| |
| * Add a basic lib/compilers/language.js (and reference to it in etc/config/language.defaults.properties as the **compilerType**) |
| |
| * You can check http://127.0.0.1:10240/api/compilers to be sure your language and compiler are there |
| |
| * Make an installer on [compiler-explorer-image](https://github.com/mattgodbolt/compiler-explorer-image) |
