any easy way to revert last do, or rather undo last action?

[vt128]

It seems that todo.txt.bak can be helpful to revert last action on todo.txt, but done.txt doesn't have such thing.

so can you please let me know if there is such a plugin or verb in future?

todo.txt is modified by many actions, and in various ways (add tasks, delete tasks, modify parts of a task). Internally, these modifications are done via sed, and that creates the todo.txt.bak file.

For done.txt, it is only ever appended to, via the archive action (or auto-archiving if configured). So undoing here means removing task(s) from the end and moving them back to todo.txt. You don't need a backup file to do this correctly; a simple text editor (or sed) will do.

Unless you enable auto-archiving, the main undo procedure for accidentally done tasks is entirely in todo.txt; I usually would not use the .txt.bak file for that, but rather use the built-in replace action or a custom add-on like my undo. Archiving typically is only run occasionally to clean up; I do this once a week.

External tools, either from the operating system (time machine) or Dropbox can also help you recovering earlier versions of any todo.sh data file.

Thanks for your details!

Auto-archiving is enabled by default, I just turned it off via export TODOTXT_AUTO_ARCHIVE=0. Everything works just fine now ---

1. use edit plugin to edit last line with vim;
2. my own undo plugin based on git reset --hard --- however i need to commit more often;
