env -S isn't a thing on linux of course. Go back to using standard
env, which means using a stack options line, which means not using
"ghc". This new setup is probably simpler anyway. I've just had to
give up on the goal of having each script's required packages being
defined in one place; now (to they extent they are required) they
must be defined both in the script header and in compile.sh.
Using stack's script command meant that the scripts needed to be
compatible, and regularly tested, with a hledger release in stackage,
rather than the latest hledger source. This created hassles for
maintainers, contributors and sometimes for users.
To simplify things overall, we now require script users to check out
the hledger source tree and run the scripts (or, bin/compile.sh) from
there once so they compile themselves. Some notes on alternative
setups are included (in one of the scripts, and referenced by the
others). This ensures that users and our CI tests are building scripts
the same way.
Current stack does not allow a stack options line to be used with the
"stack ghc" command, unfortunately, so instead we are using env's -S
flag, which hopefully has sufficiently wide support by now, and
putting all arguments in the shebang line.
This method will probably require complete explicit --package options,
unlike "stack script", so more testing and tweaking is expected.
Probably we're going to end up with some long shebang lines.
This isn't pretty but seems like a possible way to keep things
manageable.
Across the rest of the documentation and other accounting documentation
it appears to imply that the more traditional top level name would be
revenue. In fact the income statement says that is a subtraction between
revenue and expenses to derive the income. While the account types that
hledger supports are named revenue so it seems more natural to name this
revenue.
simplifySign now covers a few more sign combinations that might arise.
And in particular, it strips a standalone sign with no number,
which simplifies sign flipping with amount-in/amount-out.
Also adds a postingDate argument to amountApplyValuation, and re-orders
the ValuationType and (Transaction/Posting) arguments to
(transaction/posting)ApplyValuation, to be consistent with
amountApplyValuation.
