I work on different ledger files. Currently, each time I call ledger-report I have to retype the command ledger -f [filename] bal. How can I get the current buffer filename to appear by default in this command?

    There is a variable ledger-reports which can be customized to contain the entire command including a dynamic determination of the filename derived from the (current-buffer). If a predefined command does not exist in ledger-reports, then the default behavior is to memorize the new command and add it to the aforementioned variable and store it in the .emacs file for future use. I am careful not to type in new commands that have not been predefined because I don't want to populate the .emacs file. Instead, I just use the down arrow key to select from the available choices ... – lawlist Dec 27 '20 at 17:01

    Here is the Github link to the exact location where the variable ledger-reports (which can be customized) is defined with four (4) default settings of bal, reg, payee, and account: github.com/ledger/ledger-mode/blob/master/ledger-report.el#L47 You can get very elaborate when creating custom commands, especially if you decide to use a little bit of Lisp to take full control over the variable ledger-reports and instead forego M-x customize-variable .... Or, you could just use the aforementioned command. – lawlist Dec 27 '20 at 17:05
