- use cpp -traditional, since the default has now changed. We want to allow
unmatched single quotes!
- use fparseln, instead of a fixed 2k buffer.
- make all locals static and move to the top. This is so we can eventually
make calendar understand languages other than us_en
- add braces and continue's to clarify things.
- replace gratuitous fprintf uses with warnx.
- replace vforks() with forks() since we tried to print errors with stdio.
- add more warnings so that we know how things fail.
XXX: Eventually we'll have to remove the cpp dependency, and we should:
- make it use m4 instead [bad, breaks compatibility]
or
- add a small cpp like parser for #include [bad, too much code]
__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that. It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.
user to:
- get entries from a file other than "calendar".
- get entries for a different date than today.
- get entries for a whole week in advance, or only one day.
