Hello everyone,

I want to jump through Python backtrace in neovim quickfix list.
To do that, I added the following ex-command:set errorformat+=%.%#File\ \"%f\"\\,\ line\ %l%.%# and this command works well.
What I would like now is to add, this command in my init.lua, But when I add the previous line, neovim raises errors when I populate the quickfix List.
This is the command I added to my init.lua :vim.opt.errorformat:append { "%.%#File \"%f\"\\, line %l%.%#" }.

Here is the error when I populate the quickfix list :
Error detected while processing function AsyncRun_Job_OnTimer[12]..<SNR>24_AsyncRun_Job_Update[40]..<SNR>24_AppendText: line 33: E377: Invalid %- in format string

Do you know how to append a new string to errorFormat ?

Thank you
