Another thing I discovered when toying around was that syntax highlighting is slightly broken for comments in these cases:
* a comment contains 0 : 0 : the entire comment (and following code till the next lone opening parenthesis) is regarded as a long string literal, and marked up as such. * if a word (probably any valid identifier) is directly followed by an opening brace (even in comments) it's highlighted as a string. I guess this is supposed to indicate functions in traditionally mathematical notation like f(x), but it should not happen in comments. ----------- It is hard to get syntax highlighting exactly right. Perhaps you could take a look at the source and see where it can be improved: http://www.jsoftware.com/gitlist/qtide.git/blob/master/lib/high/highj.cpp On 4 May 2015 at 01:19, Jan-Pieter Jacobs <[email protected]> wrote: > Hi everyone, > > I found some bugs I'd want to inform about: > * Infinite popups in plot > * comments syntax highlighting broken > * Tabula add-on broken > * Labs break each other. > > I just found another instance of an error which keeps popping up > infinitely when using plot. > A try to debug the error with the JQt debugger ended in a crash. > > A minimal example exhibiting this behavior is: > > load 'plot' > opts =: 'xlabel myxlabel; ylabel myylabel' > opts plot ;/~ i.10 > > Probably it is me doing something wrong, but as this makes me forcibly > shut down J every time I hit this error, it's pretty annoying to hunt > down my error. > ------------------------ > Another thing I discovered when toying around was that syntax > highlighting is slightly broken for comments in these cases: > > * a comment contains 0 : 0 : the entire comment (and following code > till the next lone opening parenthesis) is regarded as a long string > literal, and marked up as such. > * if a word (probably any valid identifier) is directly followed by an > opening brace (even in comments) it's highlighted as a string.
