kile_syntax_1.png

I'm using LaTeX package minted to show syntax highlight with R or BASH source code. There are certain constructions which completely mess up syntax in whole editor (see further).

I'll describe examples accompanied by screenshots. The discussed TeX source file is at https://github.com/V-Z/course-linux-command-line-bash-scripting-metacentrum/blob/master/presentation/linux_bash_metacentrum_course.tex if needed.

File kile_syntax_1.png

Probably not the best example of syntax problems I found as I show on line 1749 wrong code, the syntax highlight behaves technically probably correctly, but natural human reading would be different. Following examples are really problematic.

Files kile_syntax_2.png and kile_syntax_3.png

I don't see any wrong code on my construction with find ... | parallel... As You use (and as can be easily tested within Kile with the input file), problematic construction is whatever like '{}' causing basically rest of file to be yellow, at least to another such construction. As file kile_syntax_3.png shows changing
find . -name '*.jpg' -print | parallel --bar convert '{}' '{.}.png'
to
find . -name '*.jpg' -print | parallel --bar convert {} {.}.png
(and similarly for other cases) fixes the display issue. In any case, rendering of resulting PDF is correct. So I think this is clear bug of Kile or it's syntax highlight component.

I admit that writing on beginning of line \(ToRemember\) isn't the best idea (should be commented out or so), but what I think is bug of Kile or it's syntax highlight component is fact that it breaks syntax highlight of the \end{bashcode}, \end{frame} and following XeLaTeX code. Of course, if I comment the problematic line with \(ToRemember\) using #, everything is fine. Interestingly, line \Number doesn't cause any problem. Anyway, I think it's a bug that whatever content of bascode minted environment influences following XeLaTeX code.

Partially, Kile works correctly as the 1st slide contains incomplete 'case' construction, but same problem as with previous example, I think whatever inside bashcode minted environment shouldn't influence of highlight of "standard" XeLaTeX code. Of course, if I add 'esac' to the end, this slide will be OK, but the following will again break due to "o)" starting without "case". More generally, I think it can happen often that You need to show some construction on multiple slides, and I think the situation doesn't have good solution now. Good think is that rendering of PDF is correct, so I think it's problem with Kile.

Files kile_syntax_6.png and kile_syntax_7.png

It's similar problem as shown on files kile_syntax_2.png and kile_syntax_3.png. Construction like "${VAR}" completely break syntax highlight in Kile editor. And I think this is a bug.

Interestingly, I hadn't opened this for some time and I don't recall such issues with previous versions (I use openSUSE Tumbleweed, which is rolling-release, thus usually having newest versions of everything). Of course I'd be happy to provide any further cooperation as I'd like to see this fixed.
