Sea Lion Lunch Reminder

Be reminded to have lunch, directly on the command line.

Messages are displayed in configurable time-intervals.

Quick installation

System installation:

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

User setup:

sealion-setup

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

sealion-setup

Requirements

• Python 3
• bash, fish and/or zsh.

Quick enable and disable

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

Configuration format

Example configuration file:

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.

• sealion.conf needs to follow the existing format (using : and - at the appropriate places) or there will be errors.
• 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.

Keeping watches in a separate terminal emulator window

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.
