Pointed out by mauke in #haskell chat: this was incorrectly splitting
PATH on windows (splitting on the : in C:\...), which meant that
people using multiple drive letters on Windows might see hledger
failing to recognise installed add-on commands.
Transaction balancing is supposed to balance costs, but these were
being stripped when calculating balance assignments, causing us to
wrongly reject this transaction when the last amount is left implicit,
unlike Ledger:
2023-01-01
Assets AAA -1.1 @@ CCC 2
Assets BBB -1.2 @@ CCC 3
Expenses:Fees CCC 0.2
Assets = CCC 4.9
I'm not sure why costs were being stripped. I seem to have added it
in 2019 (to Journal.balanceNoAssignmentTransactionB in 3b47b58ae),
but this bug seems to be present even before that.
CSV rules files can now be read directly, eg you have the option of
writing `hledger -f foo.csv.rules CMD`. By default this will read data
from foo.csv in the same directory. But you can also specify a
different data file with a new `source FILE` rule. This has some
convenience features:
- If the data file does not exist, it is treated as empty, not an
error.
- If FILE is a relative path, it is relative to the rules file's
directory. If it is just a file name with no path, it is relative
to ~/Downloads/.
- If FILE is a glob pattern, the most recently modified matched file
is used.
This helps remove some of the busywork of managing CSV downloads.
Most of your financial institutions's default CSV filenames are
different and can be recognised by a glob pattern. So you can put a
rule like `source Checking1*.csv` in foo-checking.csv.rules,
periodically download CSV from Foo's website accepting your browser's
defaults, and then run `hledger import checking.csv.rules` to import
any new transactions. The next time, if you have done no cleanup, your
browser will probably save it as something like Checking1-2.csv, and
hledger will still see that because of the * wild card. You can choose
whether to delete CSVs after import, or keep them for a while as
temporary backups, or archive them somewhere.
Inner empty lines were not being skipped automatically, contrary to
docs. Now all empty lines are skipped automatically, and the `skip`
rule is needed only for non-empty lines, as intended.
This may be a breaking change: it's possible that the `skip` count
might need to be adjusted in some CSV rules files.
