getting current line number and template name from a filter

[mohas]

when using a custom filter it is very helpful to get the template name and current line that the filter is called in, is there a way to do that? so we can use it for logging purposes

Not yet, but I think it can be easily implemented. Still need further investigation, will post back before end of this week.

Published 10.18.0. You can get file name from this.token.file, and line/col from this.token.getPosition() (which is calculated from token.begin and token.input). Example here:

liquidjs/test/e2e/issues.spec.ts

Lines 519 to 525 in d705888

	const engine = new Liquid()
	engine.registerFilter('pos', function (val: string) {
	const [line, col] = this.token.getPosition()
	return `[${line},${col}] ${val}`
	})
	const result = engine.parseAndRenderSync(`\n{{ "foo" | pos }}`)
	expect(result).toEqual('\n[2,12] foo')
