alias match patterns (the part left of the =) are now case-insensitive
regular expressions matching anywhere in the account name. The
replacement string (the part right of the =) can replace multiple
matches within the account name. The replacement string does not yet
support any of the usual syntax like backreferences.
Now that balance assertions are checking only a single commodity, it can
be confusing. Eg say all your amounts are in dollars, an assertion like
"= 0" checked the dollar balance in hledger 0.23 but always succeeds in
hledger 0.24. When an assertion fails, we now report which commodity was
checked to help troubleshooting.
Amount display styles have been reworked a bit; they are now calculated
after journal parsing, not during it. This allows the fix for #196:
we now search through the amounts until a decimal point is detected,
instead of just looking at the first one; likewise for digit groups.
Digit groups are now implemented with a better type.
Digit group size detection has been improved a little:
1000,000 now gives group sizes [3,4,4,...], not [3,3,...], and
10,000 gives groups sizes [3,3,...] not [3,2,2,..].
(To get [3,2,2,...] you'd use eg 00,00,000.)
There are still some old (or new ?) issues; I don't think we handle
inconsistent decimal points & digit groups too well. But for now all
tests pass.
Can be helpful when reading Ledger files, where assertions may have
different semantics; or for getting some answers from your journal
to help you fix your assertions.
Could be called --no-assertions, but this might create surprise when it
has an effect contrary to --no-new-accounts.
I had to add another flag throughout the parsers & journal read
functions, ok for now.
- The CSV reader no longer writes a "(stdin).rules" file when reading
from stdin.
- Selection of reader(s) is now smarter when input is coming from stdin.
Previously, all readers were considered applicable for stdin. This
meant that when reading a CSV file from stdin, the journal and timelog
readers were always tried first, and if the CSV file was unparseable,
you'd see the first (journal) reader's error instead of the CSV
reader's. Now, the readers do some basic content sniffing when
reading stdin, so it generally tries only the one right reader and
we'll see the right errors.
- The read system now has more debug output.
The debug level set by `--debug[=N]` is now available to pure and
startup code as debugLevel, using unsafePerformIO.
`dbg LABEL ...` is now the go-to helper for tracing values on the
console; it produces output when the debug level is non-zero. `dbgExit`
is similar but exits immediately, avoiding further output. The
`dbgshow`, `dbgppshow` and `dbgpprint` variants allow control over the
pretty-printing method and required debug level, allowing more control
over what is displayed when.
Other cleanups: lstrace -> ltrace, pdbgAt -> pdbg, tracewith -> traceWith.
At long last. The main change is a new rules file format that aims to
be more powerful and more intuitive than v1 (hledger 0.19.x and older).
Existing rules files will need to be adapted manually to the new format.
