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
