Sea Lion Lunch Reminder

Be reminded to have lunch, directly in your prompt.

Messages are displayed in configurable time-intervals.

Example configuration

~/.config/sealion.conf

11:00 - 11:20 : lunch 11:20, in %m minutes

This will add a prompt reminder from 11:00 to 11:20 with the message "lunch 11:20, in N minutes", where N is the number of minutes left.

Quick installation

System installation:

git clone https://github.com/xyproto/sealion
cd sealion
sudo make install

User setup:

sealion-setup

Configuration

• sealion.conf needs to follow the existing format (using : and - in the appropriate places).
• Comments in sealion.conf are allowed, as long as they are single-line comments starting with #.
• If a description in sealion.conf contains %m, it will be replaced with the number of minutes left when outputting the message.

Type on or off to enable or disable Sea Lion for the current shell session.

User setup on a system where Sea Lion has already been installed

sealion-setup

Requirements

• Python 3
• bash, fish or zsh.

Alternative use: Run watch in a separate terminal emulator

Simple case:

watch sealion

For updating every 5 seconds, with no title and highlighting any differences:

watch --color --differences --no-title --interval 5 sealion

Manual Setup

The following is not normally needed, since sealion-setup handles this per user, but it helps to explain what is being set up by sealion-setup:

Manual Bash setup

• Add the following to your ~/.bashrc:

# Sea Lion Prompt Reminder
on() {
  export PROMPT_COMMAND="/usr/bin/sealion"
  off() { unset PROMPT_COMMAND; }
}

# Enable prompt messages if on the right host and not over ssh
[ $HOSTNAME = "work_pc" ] && [ ! -n "$SSH_TTY" ] && on || true

• NOTE: Change work_pc to whatever the hostname of your work PC is.

Manual Fish setup

• Add the following to your ~/.config/fish/config.fish:

# Sea Lion Prompt Reminder
function on
  function sealion --on-event fish_prompt
    /usr/bin/sealion
  end
  function off
    functions -e sealion
  end
end

# Enable prompt messages if on the right host and not over ssh
if [ (hostname) = "work_pc" ]; and not count $SSH_TTY > /dev/null; on; end

• NOTE: Change work_pc to whatever the hostname of your work PC is.

Manual Zsh setup

• Add the following to your ~/.zshrc:

# Sea Lion Prompt Reminder
on() {
  precmd() { /usr/bin/sealion }
  off() { unset -f precmd }
}

# Enable prompt messages if on the right host and not over ssh
[ "$HOST" = "work_pc" ] && [ ! -n "$SSH_TTY" ] && on || true

• NOTE: Change work_pc to whatever the hostname of your work PC is.
