Thanks,

The problem withe ctrl+r is that it’s a line history, not a command history. So if, for example, you paste a large list, map or struct into the shell it renders it useless. I use the kernel flags too, but that’s a globally shared view which is fine in some cases, but not always (I also don’t think it includes date etc…plus I haven’t found a nice way to just show the history.

Still, as you said … it’s all for fun

Love a nice bit of code hacking.

Are you aware that you can do the following (in my case in .bashrc) and it will persist history?
export ERL_AFLAGS="-kernel shell_history enabled"

Between that and the normal readline shortcuts like ctrl+r I think most of what you’re looking for is built-in.

OTOH, if you’re building it for fun - nice work!

OK, latest version:

https://github.com/nhpip/history

In addition to saving history and bindings, this version adds:

1. Supports for aliasing the History module

2. Copy/paste a command from history to the shell (so you can edit it)

3. Use ctrl+u and ctrl+k to move up and down history. Unlike the standard history search with the arrow keys this is command not line based. So, for example:

Paste:

iex(1)> config = [
...(1)>   scope: :local,
...(1)>   history_limit: :infinity,
...(1)>   hide_history_commands: true,
...(1)>   prepend_identifiers: true,
...(1)>   key_buffer_history: true,
...(1)>   command_display_width: :int,
...(1)>   save_invalid_results: false,
...(1)>   show_date: true,
...(1)>   save_bindings: true,
...(1)>   colors: [
...(1)>     index: :red,
...(1)>     date: :green,
...(1)>     command: :yellow,
...(1)>     label: :red,
...(1)>     variable: :green
...(1)>   ]
...(1)> ]
[
  scope: :local,
  history_limit: :infinity,
  hide_history_commands: true,
  prepend_identifiers: true,
  key_buffer_history: true,
  command_display_width: :int,
  save_invalid_results: false,
  show_date: true,
  save_bindings: true,
  colors: [
    index: :red,
    date: :green,
    command: :yellow,
    label: :red,
    variable: :green
  ]
]

ctrl+u:

iex(2)> config = [ scope: :local, history_limit: :infinity, hide_history_commands: true, prepend_identifiers: true, key_buffer_history: true, command_display_width: :int, save_invalid_results: false, show_date: true, save_bindings: true, colors: [ index: :red, date: :green, command: :yellow, label: :red, variable: :green ]]
