Crashes when truncating metadata

[AnshumanNeon]

Describe the bug
I try to move my cursor to a file but spf crashes when I do so. The crash logs tell that this happens when we try to truncate the text, i.e. spf tries to get metadata and because it cannot fit in metadata panel, it tries to truncate it. Then it crashes. The exact line mentioned is in file components/style.go and line 234.
I will try to work on this to find why this is happening.

To Reproduce
Steps to reproduce the behavior:

1. open superfile config folder in spf
2. Move cursor to the log file
3. See error

Expected behavior
Nothing should've happened. (At least the crash shouldn't have happened)

is the line what the function call looks like?
because if it is, then it is bad. the interger value is will cause a wrap around. It is a 20-digit number. I doubt it can be represented by golang.

Is it a problem with maxChars? How about we change it to int64.

Or i miss something

[AnshumanNeon]

int64 can have at max 19-digit It won't do any good. The problem is that how can such a high number be passed as an argument. I don't understand

i find this error in a random file
This is metadata

Okay, I figured out the cause of this error.

So there is a metadata name called
NetHttp_Server_PropertiesServersAlternative_ServiceAdvertised_Alpns
Then in order to calculate the remaining length, this method is used to calculate
(BottomWidth(m.fullWidth))-maxKeyLength-3
and the result is -2
That why error i think

Ok i fix it in here
