- Implemented Arguments::extract_read_only_filter to isolate the
arguments that pertain to read-only command filters
- Implemented Arguments::extract_write_filter to isolate the arguments
that pertain to write command filters.
- Implemented Arguments::extract_modifications to isolate the arguments
that pertain to write command modifications.
- Created stubbed Expression object.
- Began integration of Expression and Arguments into commands/CmdCustom.
- Eliminated stored arg_overrides and file_override in Context.
- Removed Filter, Subst, Task, Sequence from Context.
- Remove shadow file support. Hallelujah.
- Disabled/commented out most commands, ready for the big transition
to the new parsing style.
- Obsoleted Subst.{h,cpp}.
- Obsoleted Command::exectute 'commandLine' argument. It is worse
than unnecessary, it is an uncategorized raw argument string, which
is only really useful for the 'execute' command, which itself now
calls Arguments::combine to reconstruct the command line string.
- Obsoleted Cmd object.
- Removed Context::dispatch, renamed dispatch2 --> dispatch.
- Commented out import and custom report functionality that depends
on Cmd. This should be about as broken as taskwarrior gets. It's
all uphill from here.
