Good morning and thank you for bringing this to my attention!
When I tried the suggested configuration for lualine, it didn't work.
Let us debug step by step, the suggested configuration does work in my case thus we have to reduce it to a minimal init.lua
to test. First of all
First, when a session is not loaded, the use of .status() in the condition seemed to throw an error, since the function does not exist.
This is incorrect, even if a session isn't loaded the function still exists because the plugin is loaded (via call to its setup
function): as you can see here if no session is loaded the function just returns nil
. Are you sure you aren't doing some sort of lazy loading in your plugins that delays the loading of this one unless a session is created?
Second:
There are two differences The call to the status is in quotations, which I believe prevents it from being called unless the condition is true
I don't understand this point - if we assume (and we have to validate this assumption) that the status
function isn't loaded why would the quotation marks prevent it to be called unless true?
Thank you for the response! It may be an issue with lazy-loading on my part (e.g., not calling .setup()
until later on), I will see if I can reproduce with a minimal init.lua
.
I stumbled upon the version that works (for me) via trial-and-error, and perhaps don't fully understand why it is different.
Nonetheless, to clarify my speculation - I imagined that checking .status ~= nill
is effectively checking whether or not the function exists, and checking .status() ~= nil
is calling the function, which itself returns nil
if no session is loaded.
I'm going to close the issue and re-open if I can come up with a minimal init.lua
that reproduces the problem.
When I tried the suggested configuration for lualine, it didn't work. The suggested setup is below
I think there were two problems:
.status()
in the condition seemed to throw an error, since the function does not exist.status
returns a function, not a return value, so nothing gets printed even if the first issue is fixed.Instead, I found that the following worked well.
There are two differences
status
instead ofstatus()
