Cmd.SaveGit

Synopsis

Documentation

data SaveHistory Source #

History to be saved to disk. The updates are post-diff to know which bits of state to write, and the commit is what commit the updates are relative to, if any. If they're Nothing, then save everything.

It's very important to bundle the commit and updates together, because without the commit to know what they are relative to, the updates don't mean anything, and if they're applied on top of the wrong commit the result will be a corrupted state.

set_save_tag :: Repo -> Commit -> IO (Either.Either Text SavePoint) Source #

write_save_ref :: Repo -> SavePoint -> Commit -> IO () Source #

Create a tag for the given commit.

read_last_save Source #

Arguments

save

checkpoint :: SaveGitT.User -> Repo -> SaveHistory -> IO (Either.Either Text Commit) Source #

Checkpoint the given SaveHistory. If it has no previous commit, create a new repo.

save :: SaveGitT.User -> Repo -> Ui.State -> [Text] -> IO Commit Source #

Create a new repo, or throw if it already exists.

should_record :: Update.UiUpdate -> Bool Source #

True if this update is interesting enough to record a checkpoint for.

load

:: Repo 
-> Maybe.Maybe Commit 
-> IO (Either.Either Text (Ui.State, Commit, [Text]))

(state, commit, name of the cmd this is a checkpoint of)

load_previous_history :: Repo -> Ui.State -> Commit -> IO (Either.Either Text (Maybe.Maybe LoadHistory)) Source #

Try to go get the previous history entry.

load_next_history :: Repo -> Ui.State -> Commit -> IO (Either.Either Text (Maybe.Maybe LoadHistory)) Source #

Try to a commits that has this one as a parent.

util

infer_commit :: Repo -> String -> IO (Maybe.Maybe Commit) Source #

If a string looks like a commit hash, return the commit, otherwise look for a ref in tags/.
