We provided a very limited implementation of --display only for one use
case: to see an accurate running balance. Now that is achieved more easily
with -H/--historical, similar to the balance command, and --display
can be dropped.
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).
