Input Code
const parser = require( '@babel/parser' );
const traverse = require( '@babel/traverse' ).default;
const { codeFrameColumns } = require( '@babel/code-frame' );
const CODE = 'var a = 1;';
const ERROR = 'Number is too small';
const ast = parser.parse( CODE );
traverse( ast, {
NumericLiteral: function( path ) {
throw path.buildCodeFrameError( 'Some error' );
// throw codeFrameColumns( CODE, path.node.loc, ERROR );
},
} );Expected behavior/code
throw path.buildCodeFrameError( ERROR ) should do the same as throw codeFrameColumns( CODE, path.node.loc, ERROR ); (I guess).
