But shouldn't Lilypond check first if the syntax is correct instead of spending several seconds/minutes compiling a code that's doomed to visually fail? In this case, the large project argument doesn't hold. Other than that, it seems we have different thresholds to what it means to have usable pdf output. The "service" of a glitchy PDF that Lilypond sometimes provides is of questionable value.

I strongly disagree :-)

When there is an error, the default should be to continue as long as

possible. For large projects where the compilation takes time, you want

to have some viewable output even if there is a glitch somewhere. I also

think you are overestimating the "developing effort" -- such an option

would be absolutely trivial to add. I am not sure it is worth it though.

As David said, hiding errors is always a heuristic process. I think this

would be better addressed by a convenient "jump to first error" button

in Frescobaldi.
