Code clean-up.

* tb/crlf-conv-flags:
  convert_to_git(): safe_crlf/checksafe becomes int conv_flags

convert_to_git(): safe_crlf/checksafe becomes int conv_flags

2018-01-16T20:35:56+00:00

When calling convert_to_git(), the checksafe parameter defined what
should happen if the EOL conversion (CRLF --> LF --> CRLF) does not
roundtrip cleanly. In addition, it also defined if line endings should
be renormalized (CRLF --> LF) or kept as they are.

checksafe was an safe_crlf enum with these values:
SAFE_CRLF_FALSE:       do nothing in case of EOL roundtrip errors
SAFE_CRLF_FAIL:        die in case of EOL roundtrip errors
SAFE_CRLF_WARN:        print a warning in case of EOL roundtrip errors
SAFE_CRLF_RENORMALIZE: change CRLF to LF
SAFE_CRLF_KEEP_CRLF:   keep all line endings as they are

In some cases the integer value 0 was passed as checksafe parameter
instead of the correct enum value SAFE_CRLF_FALSE. That was no problem
because SAFE_CRLF_FALSE is defined as 0.

FALSE/FAIL/WARN are different from RENORMALIZE and KEEP_CRLF. Therefore,
an enum is not ideal. Let's use a integer bit pattern instead and rename
the parameter to conv_flags to make it more generically usable. This
allows us to extend the bit pattern in a subsequent commit.

diff: introduce DIFF_PICKAXE_KINDS_MASK

2018-01-04T23:02:40+00:00

Currently the check whether to perform pickaxing is done via checking
`diffopt->pickaxe`, which contains the command line argument that we
want to pickaxe for. Soon we'll introduce a new type of pickaxing, that
will not store anything in the `.pickaxe` field, so let's migrate the
check to be dependent on pickaxe_opts.

It is not enough to just replace the check for pickaxe by pickaxe_opts,
because flags might be set, but pickaxing was not requested ('-i').
To cope with that, introduce a mask to check only for the bits indicating
the modes of operation.

Merge branch 'bw/diff-opt-impl-to-bitfields'

2017-11-09T05:31:27+00:00

A single-word "unsigned flags" in the diff options is being split
into a structure with many bitfields.

* bw/diff-opt-impl-to-bitfields:
  diff: make struct diff_flags members lowercase
  diff: remove DIFF_OPT_CLR macro
  diff: remove DIFF_OPT_SET macro
  diff: remove DIFF_OPT_TST macro
  diff: remove touched flags
  diff: add flag to indicate textconv was set via cmdline
  diff: convert flags to be stored in bitfields
  add, reset: use DIFF_OPT_SET macro to set a diff flag

diff: make struct diff_flags members lowercase

2017-11-01T02:51:40+00:00

Now that the flags stored in struct diff_flags are being accessed
directly and not through macros, change all struct members from being
uppercase to lowercase.
