Subject: more nitpickery: difference between d.getVar() and d.expand()?
Date: Tue, 5 May 2020 09:27:04 -0400 (EDT)	[thread overview]
Message-ID: <alpine.LFD.2.21.2005050921570.14090@localhost.localdomain> (raw)


  no, wait, hear me out :-). still crawling through BB user manual,
section 3.5.2, talks about using d.getVar("X") "or for more
complicated expressions, use d.expand()".

  fair enough, but it seems like a lot of the code bounces back and
forth when getting the value of a simple variable, as in:

  libdir = d.getVar("libdir")
  libdir = d.expand("${libdir}")

given that d.getVar() by default expands the value, is there some
difference between the two statements above when specifically
accessing a single variable in the data dictionary?
