preview-tui: 1: eval: Syntax error: "(" unexpected

[FunctionDJ]

When i try to use the preview-tui plugin while hovering on a folder that's named something like this Foo (Bar) [Bat], the plugin doesn't work and preview-tui: 1: eval: Syntax error: "(" unexpected is logged which is visible when exiting nnn afterwards.

I'm running nnn on a remote machine with tmux for the tiling.

I've looked at probably related issues and PRs like #1617 and #1614 but couldn't figure out if there is a fix for this.

The issue template asks for some environment details. Please provide them, especially your bash version and preview-tui version.

@N-R-K pardon, i didn't look at the bug template correctly and deleted everything instead of what i should. i have edited the issue above.

regarding the preview-tui version, i don't know where i can find it. i've read the plugin file at ~/.config/nnn/plugins/preview-tui and no version is mentioned there. i'm running nnn v4.8-1 though, according to apt policy nnn (nnn -V doesn't appear to list the -1).

regarding "Issue exists on nnn master", i don't really know how to build binaries and i was hoping that it's okay to open issues without being able to compile nnn.

It doesn't have an explicit version. I'm going to assume that it's the one that came with your nnn version.

i'm running nnn v4.8-1

There were some fixes made to preview tui since 4.8. Try downloading the latest one from master and see if that fixes your issue.

nnn -V doesn't appear to list the -1

That -1 part is probably ubuntu's package revision number.

I tried this on master and cannot reproduce. Also, the current preview-tui script doesn't have any eval since commit 432b075.

I'm closing this off as fixed by 432b075. Upgrading to v4.9 or above should fix your issue.

@N-R-K i was finally in a situation where i could upgrade to Ubuntu 24 LTS, shipping nnn 4.9 in their repo.

Unfortunately despite removing and reinstalling the plugins, the preview-tui plugin seems to be fully broken for me now. When i trigger the plugin (regardless of where, even in an empty directory), it prints size missing right into nnn on top of the first entry, without creating a tmux split.

I have this issue on Mac 14.6.1 Sonoma. I've replaced the preview-tui code after it didn't work redownloading it, but it persists.
