- Command line arguments are now handled a little differently. Each
argument is subjected to further splitting, to break up expressions
early in the process, prior to categorization.
- Patterns are now treated as quoted string, where the quote character
is /.
- Reordered operator table so that longer operators match first, thus
disambiguating between ! and !=.
- Eliminated Expression::expand_expression.
- Modified Nibbler to know what a DOM reference looks like.
- Removed alpha equivalent operators (lt, le, gt, ge, not, eq, ne) because
these are common in descriptions (French: le, ne).
- Modified Arguments and Nibbler unit tests.
- Support and documentation for rc.patterns, which enables/disables
support for /pattern/ command line arguments.
- Support and documentation for rc.expressions, which enables/disables
support for command line expressions.
- Now canonicalizes attribute names.
- Now canonicalizes modifier names.
- New colorization (temporary) that colors all Arguments::dump output
green when processed.
- New distinction between 'old' and 'new' style command lines. Old style
is "pro:A +foo pri.not:M" with implicit "and" operators. New style
includes operators but does not include "+foo" and "/foo/".
- Many tokens are converted directly to primitive types (int, number,
string) when no further processing is required.
- Restored CmdShow to functionality, and linearized the list of supported
configuration variables, for easier insertion.
- Modified arguments.t.cpp unit tests.
- Fixed some compiler warnings.
- Added DOM detection of primitives: int, double, string.
- Began implementation of DOM task access.
- Implemented support for .startswith, .endswith, .word and .noword.
- Removed obsolete subst.t.cpp.
- Implemented an operator lookup table with type, associativity and
precedence.
- Implemented Expression::to_postfix that generates a postfix
expression list using a Dijkstra Shunt.
- Began Expression::toInfix to upgrade old-style filters to infix
algebraic filters.
- Added operator support to Arguments::categorize.
- Modified CmdCustom.cpp as a read-only command guinea-pig for the
new argument processing.
- 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.
