Bat: iTerm2 issue with fullscreen

[scalp42]

Thanks a lot for bat!

I just noticed that if you bat a file in iTerm2 and simply keep switching back and forth to fullscreen, the output gets messed up pretty bad.

Here is an example, bat a file belonging to Homebrew:

Now if I simply get out of fullscreen, output gets messed up:

You can also see the scrollbar in the terminal growing, simply switching back and forth to fullscreen (cmd+enter):

Not even sure where to start with this, but let me know if I can help!

This would be because of less, the default pager for bat. less will automatically resize itself with the terminal and re-print everything to fit the new size. The content that was on the screen before the re-print is pushed back into the scrollback buffer, which creates a jumbled mess when scrolling back up.

If you disable the pager with --paging=never, this shouldn't happen anymore. A more permanent fix would be to add export BAT_PAGER=cat export BAT_PAGER='' (thanks for the tip, @sharkdp!) to your .bash_profile file, though.

As for the last image: the line wrapping fails because the terminal was resized to a smaller width than when it was printed, which makes iTerm's text wrapping take over. Unfortunately, once bat passes control to the pager, there's no way redraw/refresh the output to fit the smaller terminal.

Thank you for helping out here, @eth-p. Just a minor comment: To disable the pager permanently, you can use export BAT_PAGER="" (instead of setting it to cat). This way, bat will not spawn an additional process.

export BAT_PAGER="" working great!

Thanks for the help, closing ❤️
