When doing a type: match we now also check the original unaliased,
unpivoted posting, as when doing an acct: match. This is effectively
how things worked with the older account type detection in hledger <1.27.
Previously, similarity completely outweighed recency, so a
slightly-more-similar transaction would always be selected no matter
how old it was. Now similarity and recency are more balanced,
and it should produce the desired transaction more often.
There is also new debug output (at debug level 1) for
troubleshooting.
Boolean queries are now prefixed with an 'expr:' prefix, making them
completely separable from old queries and making the addition of them a
little more migration proof.
The tests are updated accordingly, changes made to the tests previously
are removed and extra cautious documentation is also removed.
This commit changes some of the functions in the Query module and
changes the overall way to parse queries. Instead of using the words''
split function, this commit starts to fully parse the query, as it's
seen as a type of expression.
AND, OR, NOT, and space operators can be used. The space operator
simulates the behaviour from before, leaving a minimal amount of tests
that need to be adjusted to comply to the new behaviour.
Eg, where previously -p 'monthly from 1/15' or -M -b 1/15 would always
adjust the report start date to 1/1,
unless you used the special -p 'every 15th day of month from 1/15' form,
now the start date will not be adjusted. (It is still adjusted if
the report date is not specified explicitly, eg inferred from the journal).
This keeps behaviour consistent between report periods and periodic transactions.
'in' period expressions, like 'in 2023-01', are a grey area; they
do specify a start date (2023-01-01), although they look a bit implicit.
So previously, -p 'weekly in 2023-01' would adjust the start date to
the preceding monday (2022-12-26), but now it will start exactly on
2023-01-01 (a sunday, which also causes ugly verbose column headings).
To ensure monday based weeks and simple report headings here,
you would have to explicitly specific a start date that is a monday,
eg -p 'weekly from 2022-12-26 to 2023-02'.
