Here is the caller graph for this function:

feature_enabled()

bool feature_enabled

(

const char *

name

)

Test if a compile-time feature is enabled.

Parameters

name	Compile-time symbol of the feature

Return values

true	Feature enabled
false	Feature not enabled, or not compiled in

Many of the larger features of neomutt can be disabled at compile time. They define a symbol and use ifdef's around their code. The symbols are mirrored in "CompileOptions CompOpts[]" in this file.

This function checks if one of these symbols is present in the code.

These symbols are also seen in the output of "neomutt -v".
