Drop the special case where we hide an add-on's source version if a
compiled version is also present. Better to be simple and explicit.
Improve robustness of command parsing, eg "hledger addon.hs"
will now work even though the command is listed as "addon".
And ignore any add-ons which would shadow a built-in command
(or any of the official command aliases displayed in the command list,
like "bal" and "reg"). Built-ins may not be replaced by an add-on.
We now hide add-ons' file extensions in the commands list except when
they are needed for disambiguation. There are three cases:
- when an add-on exists with only one file extension, the extension is
not displayed.
- when an add-on has exactly two variants, one with the .[l]hs extension
and the other with none or .exe - presumably the source and compiled
versions - we omit the source version from the list.
- otherwise when an add-on has multiple variants differing by file
extension, they are listed with their extensions displayed.
In addition to hledger-X and hledger-X.hs, other common executable file
extensions will be recognised. In particular, on windows hledger now
lists hledger-web.exe as an add-on. The current list is:
bat, com, exe, hs, lhs, pl, py, rb, rkt, sh.
Periodic, cumulative and historical multicolumn balance reports are now
generated by one code path, which helps with consistency and reducing
the bug/test surface. --tree now also works with --cumulative or
--historical.
Multicolumn balance reports can now be switched to a hierarchical view
with --tree. This is similar to the single column balance report with
--no-elide, ie we do not elide boring parents into the following line.
The --flat and --tree flags are opposites; the last one to appear on
the command line is decisive (in future, if not already).
To end a transaction, period is required because there might be another
default posting being suggested, and enter usually means "accept the
default". But having to switch back and forth from enter to period
during data entry is a bit unergonomic, requiring too much thought.
Now, in the (common) case where you have entered a balanced transaction
and there are no more default postings to suggest, enter is also allowed
to end the transaction. Experimental; this might be too inconsistent.
The code is now much more manageable, faciliating further
improvements. Completion now works at all prompts, and
will insert the default value if the input area is empty.
Account and amount defaults are more robust and useful
in various situations. There might be a slight regression
with default commodity handling.
Previously executables with eg digits in their name were ignored.
It now finds all files beginning with hledger-, optionally ending with
.hs or .lhs, and with no other dots in the name.
As before, we don't check for executable permission (performance ?).
Two new multi-column balance report modes show ending balance per
period: `--cumulative`, starting from 0, and `--historical`, starting
from the historical starting balance.
The balance command's specification has been clarified and consolidated
in the Balance.hs haddock. Reports.hs has also had haddock updates. The
old AccountsReport type is now BalanceReport, still used by
single-column balance report. The new MultiBalanceReport type is used by
the multi-column reports.
Command line processing has been overhauled and made more consistent,
and now has tests and extensive debug output. More flags now work
both before and after COMMAND: -f, --rule-file, --alias, --help,
--debug, --version. Command line help, command aliases, API docs and
code have been improved.
