Given a set of gems, run a block with the LOAD_PATH narrowed to include only core ruby source paths and these gems – that is, roughly, temporarily remove all gems not listed in this call from the LOAD_PATH.
This is useful before bootsnap is fully-initialized to load gems that it depends on, without forcing full LOAD_PATH traversals.
# File lib/bootsnap/explicit_require.rb, line 25 def self.with_gems(*gems) orig = $LOAD_PATH.dup $LOAD_PATH.clear gems.each do |gem| pat = %r{ / (gems|extensions/[^/]+/[^/]+) # "gems" or "extensions/x64_64-darwin16/2.3.0" / #{Regexp.escape(gem)}-(\h{12}|(\d+\.)) # msgpack-1.2.3 or msgpack-1234567890ab }x $LOAD_PATH.concat(orig.grep(pat)) end $LOAD_PATH << ARCHDIR $LOAD_PATH << RUBYLIBDIR begin yield rescue LoadError $LOAD_PATH.replace(orig) yield end ensure $LOAD_PATH.replace(orig) end
