This increases composability and avoids some ugly case handling. We
re-export runExceptT in Hledger.Read.
The final return types of the following functions has been changed from
IO (Either String a) to ExceptT String IO a. If this causes a problem,
you can get the old behaviour by calling runExceptT on the output:
readJournal, readJournalFiles, readJournalFile
Or, you can use the easy functions readJournal', readJournalFiles', and
readJournalFile', which assume default options and return in the IO
monad.
This results in big speedups in cases when we have many transaction prices, like in examples/10000x1000x10.journal. This can be disabled with the show_costs_ option in ReportOpts.
Introduce --infer-equity option which will generate conversion postings.
--cost will override --infer-equity.
This means there will no longer be unbalanced transactions, but will be
offsetting conversion postings to balance things out. For example.
2000-01-01
a 1 AAA @@ 2 BBB
b -2 BBB
When converting to cost, this is treated the same as before.
When used with --infer-equity, this is now treated as:
2000-01-01
a 1 AAA
equity:conversion:AAA-BBB:AAA -1 AAA
equity:conversion:AAA-BBB:BBB 2 BBB
b -2 BBB
There is a new account type, Conversion/V, which is a subtype of Equity/E.
The first account declared with this type, if any, is used as the base account
for inferred equity postings in conversion transactions, overriding the default
"equity:conversion".
API changes:
Costing has been changed to ConversionOp with three options:
NoConversionOp, ToCost, and InferEquity.
The first correspond to the previous NoCost and Cost options, while the
third corresponds to the --infer-equity flag. This converts transactions with costs
(one or more transaction prices) to transactions with equity:conversion postings.
It is in ConversionOp because converting to cost with -B/--cost and inferring conversion
equity postings with --infer-equity are mutually exclusive.
Correspondingly, the cost_ record of ReportOpts has been changed to
conversionop_.
This also removes show_costs_ option in ReportOpts, as its functionality
has been replaced by the richer cost_ option.
