vimvim-plugin
Why is 'indentexpr=' printed constantly?
I have made some modifications in my .vimrc (install some plugins, like for example fzf, include some extra configurations, etc).
Continuing to work with vim, there is something I don't like, the screen printing of indentexpr=. It happens when I am going to start vim or when doing some other action inside the project (commands/navigation).

Solution
Line 14:
set indentexpr
That command prints the value of indentexpr:
indentexpr= " value is empty
indentexpr=Foo() " value is Foo()
Since you have that command in your vimrc, the value is output every time your vimrc is sourced. Remove it.
