From 3442c3d11df16d7cd3867b133a8ec6ddd21a8839 Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Tue, 7 Apr 2020 10:27:52 -0400 Subject: sequencer: make read_oneliner() accept flags In a future commit, we will need read_oneliner() to accept flags other than just `skip_if_empty`. Instead of having an argument for each flag, teach read_oneliner() to accept the bitfield `flags` instead. For now, only recognize the `READ_ONELINER_SKIP_IF_EMPTY` flag. More flags will be added in a future commit. The result of this is that parallel topics which introduce invocations of read_oneliner() will still be compatible with this new function signature since, instead of passing 1 or 0 for `skip_if_empty`, they'll be passing 1 or 0 to `flags`, which gives equivalent behavior. Mechanically fix up invocations of read_oneliner() with the following spatch @@ expression a, b; @@ read_oneliner(a, b, - 1 + READ_ONELINER_SKIP_IF_EMPTY ) and manually break up long lines in the result.
