hledger-pijul - easy version control for your hledger journal.
|
|
|
|
An experimental prototype, currently works for the default journal only.
|
|
This uses pijul, the VCS most likely to support a simple just-works UI.
|
|
A pijul repo in the main file's directory, and a pijul commit-signing key,
|
|
will be autocreated if needed.
|
|
|
|
Subcommands:
|
|
|
|
hledger pijul record [MSG] - record the journal's files (as listed by 'files')
|
|
hledger pijul status - show unrecorded changes (after first record)
|
|
hledger pijul log - list the journal's change history (after record)
|
|
hledger pijul - show this help
|
|
|
|
Extra arguments are passed to pijul (pijul flags should be preceded by --).
|
|
You can install these as more convenient top-level commands by creating
|
|
hledger-record, hledger-status, hledger-log scripts like:
|
|
|
|
#!/bin/sh
|
|
hledger-pijul record "\$@"
