You can save frequently used options and arguments in an argument file, one per line, then reuse them via a @FILE argument on the command line.
Here's an example.
I keep frequently-used options for quick daily reports in a file
simple.args. The name can be anything; I use a
so I can find these easily. Here's the content of
--alias=/:(business|personal):/=: --alias=/:(bank|cash|online):/=: --alias=/:bofi:/=:b --alias=/:unify:/=:u --alias=/:wf:/=:w -2 cur:.
The format is one command-line flag or command-line argument per line. Special characters should have one less level of quoting than at the command prompt (so no quotes around those (|) characters), and spaces should be avoided except inside quotes (so = is used between flags and arguments).
Now if I write
@simple.args in a hledger command line, it will be replaced
by all of the above options/flags.
(In case you're wondering about this example: it removes some detail, giving simplified reports which were easier for me to read at a glance):
- the aliases simplify the chart of accounts, hiding some distinctions (eg business vs. personal) and flattening some bank account names
-2depth flag limits account depth to 2, hiding deeper subaccounts
cur:.query argument shows only single-character currencies, hiding a bunch of cluttersome commodities I don't want to see
Generate a balance report showing the simplified accounts:
$ hledger bal @simple.args
Start a live-updating hledger-ui showing the simplified asset accounts only:
$ hledger-ui --watch @simple.args assets
Options in the arguments file can be overridden by similar options later on the command line, in the usual way. Eg, to show just a little more account detail:
$ hledger bal @simple.args -3
If you actually need to write an argument beginning with @,
eg let's say you have an account pattern beginning with that character,
you'll want a way to disable this feature. On unix systems at least,
you can do that by inserting a
-- (double hyphen) argument first. Eg:
$ hledger bal @somewhere.com # looks for additional arguments in the ./somewhere.com file $ hledger bal -- @somewhere.com # matches account names containing "@somewhere.com"
On windows, this double hyphen trick might require a hledger built with GHC 8.2+.
