Debugging Errors

[seyonv]

Sorry if this is not appropriate to be marked as an issue. I thought this may be an appropriate place as I'm specifically wondering about debugging LESS when using less-rails(.css.less files).

How do you debug errors in your .css.less file?

If I simply forget a semicolon in the file, when I load the file in the browser, I get
Less:Error at /Unrecognised input (in .../lc3.css.less)

It only tells me the filename where the error is but no indication as to what line the error occurs on

What I'm currently doing is running $lessc app/assets/stylesheets/lc3.css.less
which tells me the line there's a "parse error" on.

Seems like an inefficient way to do it though, was wondering if anyone could share their process[detailed :O] for debugging LESS (and if they use source maps or something else to be able to edit live in browser)

i tried to include semantic-ui today which is using shitty less and all i get is

/home/tim/.rvm/gems/ruby-2.6.3/gems/less-2.6.0/lib/less/parser.rb:74:in block (2 levels) in parse': expected ')' got 'o' (Less::Error)`

i can go line by line and always get this. i don't know what any error should mean. i wasted already 1 hour on my livestream with this and my viewers find it hilarious to see that i'm not capable of including a 3rd party library. i blame semantic-ui for it tho.

if there would be a solid error message, life would be easier
