diff --color-words: bit of clean-up

2009-10-31T21:25:15Z

When we introduced the "word diff" mode, we could have done one of three things: * change fn_out_consume() to "this is called every time a line worth of diff becomes ready from the lower-level diff routine. This function knows two sets of helpers (one for line-oriented diff, another for word diff), and each set has various functions to be called at certain places (e.g. hunk header, context, ...). The function's role is to inspect the incoming line, and dispatch appropriate helpers to produce either line- or word- oriented diff output." * introduce fn_out_consume_word_diff() that is "this is called every time a line worth of diff becomes ready from the lower-level diff routine, and here is what we do to prepare word oriented diff using that line." without touching fn_out_consume() at all. * Do neither of the above, and keep fn_out_consume() to "this is called every time a line worth of diff becomes ready from the lower-level diff routine, and here is what we do to output line oriented diff using that line." but sprinkle a handful of 'are we in word-diff mode? if so do this totally different thing' at random places. This patch is to at least abstract the details of "this totally different thing" out from the main codepath, in order to improve readability. We can later refactor it by introducing fn_out_consume_word_diff(), taking the second route above, but that is a separate topic. Signed-off-by: Junio C Hamano

diff --color-words -U0: fix the location of hunk headers

2009-10-30T16:42:56Z

Colored word diff without context lines firstly printed all the hunk headers among each other and then printed the diff. This was due to the code relying on getting at least one context line at the end of each hunk, where the colored words would be flushed (it is done that way to be able to ignore rewrapped lines). Noticed by Markus Heidelberg. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

diff -B: colour whitespace errors

2009-09-15T09:41:03Z

We used to send the old and new contents more or less straight out to the output with only the original "old is red, new is green" colouring. Now all the necessary support routines have been prepared, call them with a line of data at a time from the output code and have them check and color whitespace errors in exactly the same way as they are called from the low level diff callback routines.

diff.c: emit_add_line() takes only the rest of the line

2009-09-15T09:41:02Z

As the first character on the line that is fed to this function is always "+", it is pointless to send that along with the rest of the line. This change will make it easier to reuse the logic when emitting the rewrite diff, as we do not want to copy a line only to add "+"/"-"/" " immediately before its first character when we produce rewrite diff output.
