# shell-history

Shell history stored in SQLite, synced via git.

## Install

```
cd $HOME/dev/vlv
git clone git.meatbag.se:vlv/shell-history.git shell-history
mkdir histdb

cd shell-history
go build -o shist .
sudo install shist /usr/local/bin/
```

## Migrate from log files

```
shist import ~/dev/vlv/histdb/
```

## zsh

`~/.zshrc`:

```zsh
autoload -Uz compinit promptinit add-zsh-hook

histdb_dir="$HOME/dev/vlv/histdb"

_add_history() {
    if test "$(id -u)" -ne 0; then
        local cmd=$(fc -ln -1)
        cmd=${cmd//$'\n'/\\n}
        shist add \
            --timestamp "$(date --utc --iso-8601=seconds)" \
            --hostname "$(hostname)" \
            --dir "$(pwd)" \
            -- "$cmd"
    fi
}
add-zsh-hook precmd _add_history

hsup() { shist sync "$histdb_dir" }

hs() {
    local copy_cmd=
    case "$XDG_SESSION_TYPE" in
        x11)     copy_cmd="xsel --clipboard" ;;
        wayland) copy_cmd="wl-copy --trim-newline" ;;
        *) echo "Session type not detected."; return ;;
    esac

    local entry="$(
        shist search "$@" | \
        fzf --ansi --disabled --query "${*:-}" \
            --bind "start:reload:shist search {q}" \
            --bind "change:reload:sleep 0.1; shist search {q} || true" \
            --delimiter ' '
    )"

    local entry_cmd="$(<<<$entry awk -F' ' '{ print substr($0, index($0, $4)) }')"
    entry_cmd="${entry_cmd//\\n/$'\n'}"

    if [[ "$entry" ]]; then
        eval $copy_cmd <<< "$entry_cmd" >/dev/null
        echo "Copied to clipboard." >&2
    fi
}
```

## Usage

```
shist [--db PATH] add --timestamp T --hostname H --dir D -- COMMAND...
shist [--db PATH] search [--host H] [--dir D] [--after T] [--before T] [--limit N] [QUERY...]
shist [--db PATH] sync DIR
shist [--db PATH] import DIR
shist [--db PATH] stats
```

Default `--db`: `~/.local/share/shist/history.db`

## Legacy

The old shell scripts (`search.sh`, `sync.sh`) are kept for backward compatibility
during migration. They continue to work with the log files in the git repo.
