To enable syntax highlighting for financial indicator functions (like MA, EMA, CLOSE, etc.) within the editor, you must configure the editor mode to text/javascript and modify the CodeMirror JavaScript mode definition to include financial-specific keywords and styles.
1. Configure the Editor Mode
In your App.vue, set the editor configuration to use the JavaScript mode:
mode: 'text/javascript'
2. Modify the CodeMirror JavaScript Mode
Locate the following file in your project:
node_modules/codemirror/mode/javascript/javascript.js
Replace the existing keywords() function with a custom implementation that maps financial keywords to specific styles (e.g., functionname, dataname, colorname). This allows the editor to visually distinguish between indicator functions, market data variables, and color constants.
// Example of the custom keywords function structure to be inserted into javascript.js
var keywords = function(){
function kw(type) {return {type: type, style: "keyword"};}
var FUNCTION_NAME=kw('functionname');
var DATA_NAME={type: "dataname", style:'variable-2'};
var LINE_WIDTH_NAME=kw('linewidth');
var DRAW_NAME=kw("drawname");
var COLORRED={type: "colorname", style:'colorred'};
// ... other color definitions
var jsKeywords = {
"MA":FUNCTION_NAME,
"EMA":FUNCTION_NAME,
"CLOSE":DATA_NAME,
"C":DATA_NAME,
"COLORRED":COLORRED,
// ... other financial keywords
};
return jsKeywords;
}();
