Check if startline value is valid before passing it to input.State(), to prevent a theoretically possible race when the number of lines changes in the meantime, causing an out of bounds access. Actually this race cannot happen: ReHighlightStates() is only called from the main goroutine, and the line array is modified, again, only by the main goroutine. So for now this change is rather cosmetic: it is just to make the highligher API implementation self-sufficiently safe without assumptions about which goroutines are using which API functions and how. |
