If the CSV records appear to have been in reverse date order,
we'll now reverse them all before also sorting by transaction date,
so that the original order of same-day transactions is preserved.
We detect this using a simple heuristic: if the first converted
transaction's date is later than the last's.
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.
