[PATCH 1/3] Implement parsing for new core.whitespace.* options.
From: David Symonds <hidden>
Date: 2016-06-15 22:43:46
Each of the new core.whitespace.* options (enumerated below) can be set to one of: * okay (default): Whitespace of this type is okay * warn: Whitespace of this type should be warned about * error: Whitespace of this type should raise an error * autofix: Whitespace of this type should be automatically fixed The initial options are: * trailing: Whitespace at the end of a line * space-before-tab: SP HT sequence in the initial whitespace of a line * space-indent: At least 8 spaces in a row at the start of a line Example usage: [core "whitespace"] trailing = autofix space-before-tab = error space-indent = warn Signed-off-by: David Symonds <redacted> --- cache.h | 16 ++++++++++++++++ config.c | 28 ++++++++++++++++++++++++++++ environment.c | 3 +++ 3 files changed, 47 insertions(+), 0 deletions(-)
