hledger run does not support arg files

[Xitian9]

hledger run does not yet seem to properly parse argfiles. I would expect these two commands to produce the same results, but the second command does not display any accounts.

echo "--depth=1\nassets" > test.args

hledger balance @test.args
hledger run <<< "balance @test.args"

Additional colour:

• run uses getHledgerCliOpts' (see here) to parse [String] into CliOpts

• getHledgerCliOpts' does not handle arg files, it assumes they were already interpolated by the toplevel Cli.hs here

• expandArgsAt stops at '--' , so run needs to keep applying expandArgsAt itself inside each -- - separated block
