Micro: Syntax highlighting failure

[skontar]

Hi. First, thank you for the neat editor!

I have found an issue with syntax highlighter, when sometimes it sets the whole view to "comment" under some circumstances.

To reproduce:

_The file to open:_
https://github.com/skontar/update-checker/blob/a810f6b71449dbbc03d033fc598f48151892a799/update_checker.py

_The terminal size:_
80x24 (xfce4-terminal)

_Scroll so these lines are the only visible:_
83-104

See the screenshot for details.

Hmm unfortunately there is nothing I can do about this without making a lot of changes to the syntax highlighting engine. I do plan on making the changes, but I can't do it right now.

The issue is caused by micro only checking a subset of the buffer for syntax highlighting (for speed purposes), but since Python uses """ for both starting a comment and ending a comment, micro can't know if a """ is the start of a comment, or if it is the end of a comment which started out of the subset being checked.

Understood. Hopefully you will be able to fix that in the future by some clever optimization. Unfortunately I know nothing about Go, so I cannot help. Keep up great work, you have saved me from Nano and Vim suffering!

I have a similar error on the left to the right Тerminator Gnome Terminal

That seems like syntax highlighting is simply not working in Terminator. This is probably because your TERM variable is set to xterm. You can fix this by settings TERM=xterm-256color or by changing the colorscheme in micro to simple (> set colorscheme simple).

Thank you! it helped me
TERM=xterm-256color

After reloading and then saving a file the syntax highlighting fails entirely and no subsequently opened files are highlighted. When multiple tabs/splits are open, it fails on the saved one, other splits/tabs retain highlighted state until they are saved.

Fixed in #593.
