Vis parser crashes on my River config file

[FoundOne]

River is a Wayland tiling compositor. The file is a simple shell script and it executes normally. When I open it with vis it starts fine until I scroll to a certain point. Then I get an error /usr/share/vis/lexers/bash.lua:29: attempt to concatenate a nil value (local 'delimiter')

My platform is Manjaro-arm unstable RK3399.

Here is the file (I'm really frustrated that I can't attach it as a file):

Thanks for the report, what is your vis version i.e. the output of vis -v?

I suspect his might be fixed by e57851806592f5ea4ee48303b97a5f59731370c5.

There is also a related upstream issue about the same functionality (highlighting here documents). What is the status of that @silasdb?

Also I don't know why you couldn't attach your file. You could use a service like ix.io to make it available somewhere.

It says vis v0.7 +curses +lua +tre +acl

I intend to work on it this week.

[FoundOne]

It no longer crashes with vis v0.7 +curses +lua +tre +acl for me. I know it says the same version, but I've got a new package with Arch-arm resently and it works. I'm more and more confident of using vis as my main editor. Thanks, guys.

[dkwo]

I'm still hitting the same exact issue on void linux. Will backport the fix for now.

Closing this since the fix is present in vis-v0.8.
