This was supposed to be just a fix for #1404 but upon visiting the source
several issues became apparent and that is why the commit grew a bit more than
expected. A complete list of changes bellow:
* Fix#1404
No more orphaned temporary directories. Commands, options, etc. that used to be
stored in there are included at build-time as here documents in the source.
* Fix artifacts in =/tmp= after build
Upon fixing the above I became aware that the build itself was leaving behind a
heap of artifacts in =/tmp= that were not taken care of with a ~make clean~.
Fixed by using temporary files and directories in the build directory. Makefile
and build scripts adjusted.
* Produce command aliases
Regular expressions in build scripts changed to produce all command aliases
except single letter ones (see below)
* Do not propose single letters completions
It is simply not useful and adds a lot of noise. It makes completion slower as
well because you need to hit yes on the prompt:
> Display all 200 possibilities? (y or n)
=output-options.sh= now excludes those.
* Query filters simplified
Keep only the prefix of the filter with the colon in =query-filters.txt=. This
change has two reasons:
- Single letter completions are not useful (see above)
- It allows for completion suggestions specific to each
- Bonus reason: it's a completion engine, not a user manual.
* Fix completion impacts on global environment
The completion script was making a couple of changes to the global environment
which had an impact for the rest of the shell session.
~set -o pipefail~: the change is hidden from the user and could lead to subtle
errors throughout the shell session
COMP_WORDBREAKS=" ": this affects subsequent completions for us and other
programs too. I exclude the colon =:= from its value and use
~compopt -o filenames~ to handle escaping of special characters for us. I would
like to find a solution without messing with COMP_WORDBREAKS but it is not
straight forward.
* Fix hiding of legit subcommands
Completion was hiding all possibilities if a subcommand happens to be the prefix
of another. On typing ~balance~, one should be proposed ~balancesheet~ and
~balancesheetequity~ as well.
* Return early
Try to complete depending on the current context and return immediately if
successful. Keep completion list relevant and as short as possible.
* Context aware completion
- Add handlers for option parameter completion, see _hledger_compreply_optarg()
- Add handlers for query filters:, see _hledger_compreply_query()
- Use --file and --rules-file arguments when proposing completions for the
above, see _hledger()
- Propose only top level accounts at first. Again, keep it short and focused.
* Custom ~compgen~ wrapper
~compgen~ is fairly complicated. There is no way to feed it a word list with
literals. It will mangle your input in so many ways that we cannot trust it. To
work around this several wrappers are used: _hledger_compgen() works with
_hledger_quote_by_ref() to process and escape newline separated input which is
then fed to ~compgen~ and finally in ~COMPREPLY~ through _hledger_compreply()
and _hledger_compreply_append(). It sounds messy and I guess it is, I would like
to find a more straight forward way to do it. I think it is still a way better
and safer interface with ~readline~ than trying to ~grep~ our way through.
* Replace ~declare~ with ~local~
Again, this script is sourced by the shell -- keep variable scopes as narrow as
possible.
* Use ~compopt -o nosort~
Often I resort to using it to keep different groups of completions together.
Whether this is more ergonomic or not is subjective. But our input lists are
already sorted at build-time so why not. Sort manually =query-filters.txt= when
changing it.
* Remove irrelevant comments
And add some new ones :)
I think that is all. Give it a spin, try to abuse it, in and outside of quotes,
with some funky accounts, payees, tags, whatever, and tell me where it breaks or
behaves unexpectedly.
- Consume list immediately in commodityStylesFromAmounts.
This and/or the other strictness fixes below reduce memory and time
usage, a lot, for journals with many @@ total prices.
- Include sign in TotalPrice in Amount, rather than relying on the sign of aquantity.
Journal entries still require a positive @@ price, but now the sign is
set after parsing, rather than when converting in amountToCost.
The reason for this change is that, if we're going to perform arithmetic
on Amount with TotalCost, then the presence of aquantity=0 means that
amountToCost would render the total cost as 0, because signum 0 == 0.
This makes amount arithmetic more consistent, and allows negative
prices to be represented. It also means that total prices override
the primary amount: 0A @@ 1B is now 1B, not 0.
- Make fields of Amount, AmountPrice, AmountStyle, and DigitGroupStyle
strict.
- Distinguish between an Amount having quantity (or rounded quantity 0),
and having both quantity and totalprice 0 (or rounded to 0).
- normaliseHelper now uses a strict Map for combining amounts
internally, closing a big space leak.
This also now combines Amounts with TotalPrices in the same commodity
when normalising; amounts with TotalPrices were previously never
combined.
- (amount|mixedAmount)(Looks|Is)Zero functions now check whether both
the quantity and the cost are zero. This is usually what you want, but
if you do only want to check whether the quantity is zero, you can run
mixedAmountStripPrices (or similar) before this.
both the quantity and the cost are zero. This is usually what you want,

(multiply|divide)(Mixed)?Amount now also multiply or divide the
TotalPrice if it is present, and the old
(multiply|divide)(Mixed)?AmountAndPrice functions are removed.

This makes journal entries like the following impossible to balance:
2000-01-01
a 0 @@ 10 A
b -10 A
If you forget that the argument is required by the --match
option, and not the command as a whole - eg if instead of
hledger print --match somebank -x
you write:
hledger print --match -x somebank
that gets quietly parsed as:
hledger print --match="-x"
which is not great. Adding --debug now at least gives some insight:
hledger print --match -x somebank --debug
finding best match for description: "-x"
similar transactions:
...
add --debug=1 shows the top hits for similar past transactions.
added:
Hledger.Cli.Utils.journalSimilarTransaction
provides --debug=1 output
changed:
Hledger.Cli.Commands.Add.transactionsSimilarTo -> Hledger.Data.Journal.journalTransactionsSimilarTo
now takes an extra number-of-results argument
It would not add the tag when a comment already existed.
This affected hledger-print-location.hs and probably
the generated-transaction: tag in periodic transactions.
For clarity; infer-value was too vague. The old spelling remains
supported for compatibility, but is now deprecated.
When typing, --infer-market or even --infer (for now) is sufficient.
On the accounts screen and register screen we round amounts according
to commodity styles, but when you drill down to a transaction you
probably want to see the unrounded amounts.
Ensures parseable and more sensible-looking output in more cases, and behaves more like Ledger's print.
There is still an issue with adding trailing zeroes, which would be nice to prevent.
