From 3b4adabee14855e6ce5345567ceeb566917625be Mon Sep 17 00:00:00 2001 From: Andrew Gallant Date: Sat, 28 Dec 2013 09:22:33 -0500 Subject: The `sync` and `xinput` extensions now use the `switch` field, which XGB does not currently support. Therefore, I'm removing the sync and xinput extensions. This affects issues #11 and #13. --- nexgb/sync/sync.go | 2127 ---------------------------------------------------- 1 file changed, 2127 deletions(-) delete mode 100644 nexgb/sync/sync.go (limited to 'nexgb/sync') diff --git a/nexgb/sync/sync.go b/nexgb/sync/sync.go deleted file mode 100644 index 3234d60..0000000 --- a/nexgb/sync/sync.go +++ /dev/null @@ -1,2127 +0,0 @@ -// Package sync is the X client API for the SYNC extension. -package sync - -// This file is automatically generated from sync.xml.
