1 Introduction

Wyrd is a text-based front-end to Remind ⟨https://dianne.skoll.ca/projects/remind⟩ , a sophisticated
calendar and alarm program. Wyrd serves two purposes:

1) It displays reminders in a scrollable timetable view suitable for visualizing your calendar at a
glance.
2) It makes creating and editing reminders fast and easy. However, Wyrd does not hide Remind's textfile
programmability, for this is what makes Remind a truly powerful calendaring system.

Wyrd also requires only a fraction of the resources of most calendar programs available today.

2 Installation

This section describes how to install Wyrd by compiling from source. Wyrd has been packaged for a number
of popular Linux/Unix variants, so you may be able to save yourself some time by installing from a
package provided by your OS distribution.

Wyrd is designed to be portable to most Unix-like operating systems, including GNU/Linux, *BSD, and Mac
OS X. Before installing Wyrd, your system must have the following software installed:

• OCaml ⟨https://ocaml.org/⟩
>= 4.08
• the ncurses library ⟨https://invisible-island.net/ncurses/⟩
(and development headers)
• OCaml Curses ⟨https://github.com/mbacarella/curses⟩

• Remind ⟨https://dianne.skoll.ca/projects/remind/⟩
>= 4.0.0
• GNU make ⟨https://www.gnu.org/software/make/⟩

• the Unix pager application, less

After installing the OCaml compiler, Wyrd may be compiled and installed through any of the following 3
methods:

2.1 Method 1: GNU make and OCaml findlib

1) Install the OCaml findlib package for your operating system:
https://repology.org/project/findlib/related
2) Install the OCaml curses package for your operating system:
https://repology.org/project/ocaml:curses/versions
3) Execute the following commands at the root of the source tree:

export PREFIX=/usr
make
make install

On the BSDs, GNU make is usually available under the name gmake instead of make.

2.2 Method 2: Dune

1) Install the Dune package for your operating system: https://repology.org/project/dune/versions
2) Install the OCaml curses package for your operating system:
https://repology.org/project/ocaml:curses/versions
3) Execute the following commands at the root of the source tree:

export WYRD_SYSCONFDIR=/etc
dune build --release
dune install --prefix=/usr --sections=bin

2.3 Method 3: OPAM

1) Install the OPAM package for your operating system: https://opam.ocaml.org/doc/Install.html
2) Execute the following commands at the root of the source tree:

opam init -c ocaml-system -n
opam install -y ./wyrd.opam

3) Wyrd may then be started with this command:

opam exec wyrd

3 Quick Start

This section describes how to use Wyrd in its default configuration. After familiarizing yourself with
the basic operations as outlined in this section, you may wish to consult the Advanced Configuration
section to see how Wyrd can be configured to better fit your needs.

4 Overview

Before attempting to use Wyrd, learn how to use Remind. Wyrd makes no attempt to hide the details of
Remind programming from the user. Aside from reading the Remind manpage, you may get some useful pointers
by reading Mike Harris's article on 43 Folders ⟨https://www.43folders.com/2005/02/24/guest-mike-harris-
looks-at-remind⟩ , Dianne Skoll's writeup on Linux Journal ⟨https://www.linuxjournal.com/article/3529⟩ ,
or the Remind Wiki ⟨https://dianne.skoll.ca/wiki/Remind⟩

You can launch Wyrd using the default reminder file by executing wyrd. If desired, a different reminder
file (or reminder directory) may be selected by executing wyrd <filename>.

At the top of the window is a short (incomplete) list of keybindings.

The left window displays a scrollable timetable view, with reminders highlighted in various colors. If
the DURATION specifier is used for a reminder, the highlighted area is rendered with an appropriate size.
Overlapping reminders are rendered using one of four different indentation levels so that all reminders
are at least partially visible. If the current time is visible in this window, it is highlighted in red.

The upper right window displays a month calendar, with the color of each day representing the number of
reminders it contains. The colors range across shades of white to blue to magenta as the number of
reminders increases. The selected date is highlighted in cyan; if the current date is visible, it is
highlighted in red.

The lower right window displays a list of the untimed reminders falling on the selected date.

The bottom window displays the full text of the MSG for the reminder or reminders that are currently
selected.

5 Navigation

──────────────────────────────────────────────────────────────────────────────
Action Keypress
──────────────────────────────────────────────────────────────────────────────
scroll up and down the schedule <up>, <down> or k, j
jump back or forward by a day <pageup>, <pagedown> or 4, 6 or <, >
or H, L
jump back or forward by a week 8, 2 or [, ] or K, J
jump back or forward by a month {, }
jump to current date and time <home>
jump to the next reminder <tab>
switch between schedule and untimed <left>, <right> or h, l
reminders window
zoom in on the schedule z
scroll the description window up and d, D
down
──────────────────────────────────────────────────────────────────────────────

Notice that if you have a numeric keypad, the {4, 6, 8, 2} keys will let you move directionally in the
month calendar view at the upper-right of the screen. Similarly, {H, J, K, L} will cause directional
calendar movement using the standard mapping from vi(1).

In addition to the hotkeys provided above, Wyrd lets you jump immediately to a desired date by pressing
'g', entering in a date specifier, and then pressing <return>. Any of the following date specifiers may
be used:

• 8 digits representing year, month, and day: YYYYMMDD
• 4 digits representing month and day (of current year): MMDD
• 2 digits representing day (of current month and year): DD

(The date specifier format may be changed to DDMMYYYY; consult the section on Configuration Variables.)

6 Editing Reminders

Note: By default, Wyrd is configured to modify your reminder files using the text editor specified by the
$EDITOR environment variable. (This configuration has been tested successfully with a number of common
settings for $EDITOR, including 'vim', 'emacs', and 'nano'.) If you wish to use a different editor, see
Advanced Configuration.

If you select a timeslot in the schedule view, then hit 't', you will begin creating a new timed
reminder. Wyrd will open up your reminder file in your favorite editor and move the cursor to the end of
the file, where a new reminder template has been created. The template has the selected date and time
filled in, so in many cases you will only need to fill in a MSG value.

Similarly, hitting 'u' will begin creating an untimed reminder. 'w' will create a weekly timed reminder,
and 'W' will create a weekly untimed reminder; 'm' will create a monthly timed reminder, and 'M' will
create a monthly untimed reminder.

The keys 'T' and 'U' also create timed and untimed reminders (respectively), but first will provide a
selection dialog for you to choose which reminder file you want to add this reminder to. The set of
reminder files is determined by scanning the INCLUDE lines in your default reminder file. (If you use a
reminder directory, then all *.rem files in that directory will be available along with all INCLUDEd
files.)

If you select a reminder (either timed or untimed) and hit <return>, you will begin editing that
reminder. Wyrd will open up the appropriate reminders file in your editor and move the cursor to the
corresponding REM line.

If you select a timeslot that contains multiple overlapping reminders, Wyrd will provide a dialog that
allows you to select the desired reminder.

If you hit <enter> on a blank timeslot, Wyrd will begin creating a new timed or untimed reminder
(depending on whether the timed or the untimed window is selected).

Finally, pressing 'e' will open the reminder file in your editor without attempting to select any
particular reminder.

7 Quick Reminders

Wyrd offers an additional mode for entering simple reminders quickly. Press 'q', and you will be prompted
for an event description. Simply enter a description for the event using natural language, then press
<return>. Examples:

• meeting with Bob tomorrow at 11
• drop off package at 3pm
• Wednesday 10am-11:30 go grocery shopping
• Board game night 20:15 next Fri
• 7/4 independence day
• 7/4/2007 independence day (next year)
• independence day (next year) on 2007-07-04

If your event description can be understood, Wyrd will immediately create the reminder and scroll the
display to its location.

Currently the quick reminder mode tends to favor USA English conventions, as generalizing the natural
language parser would require some work.

Wyrd also allows you to use the "quick reminder" syntax to create new reminders from the command line,
using the -a or --add options. For example,

wyrd --add "dinner with neighbors tomorrow at 7pm"

would create a new reminder for tomorrow evening. When used in this mode, Wyrd exits silently with error
code 0 if the reminder was successfully created. If the reminder could not be created (e.g. if the
reminder syntax could not be parsed), Wyrd prints an error message and exits with a nonzero error code.

8 Cutting and Pasting Reminders

Reminders can be easily duplicated or rescheduled through the use of Wyrd's cutting and pasting features.

Selecting a reminder and pressing 'X' will cut that reminder: the corresponding REM line is deleted from
your reminders file, and the reminder is copied to Wyrd's clipboard. To copy a reminder without deleting
it, use 'y' instead.

To paste a reminder from the clipboard back into your schedule, just move the cursor to the desired
date/time and press 'p'. Wyrd will append a new REM line to the end of your reminders file, and open the
file with your editor. The REM line will be configured to trigger on the selected date. If the copied
reminder was timed, then the pasted reminder will be set to trigger at the selected time using the
original DURATION setting. (Additional Remind settings such as delta and tdelta are not preserved by
copy-and-paste.)

If you wish to paste a reminder into a non-default reminders file, use 'P'. This will spawn a selection
dialog where you can choose the file that will hold the new reminder.

WARNING: Cutting a reminder will delete only the single REM command responsible for triggering it. If you
are using more complicated Remind scripting techniques to generate a particular reminder, then the cut
operation may not do what you want.

9 Viewing Reminders

Aside from viewing reminders as they fall in the schedule, you can press 'r' to view all reminders
triggered on the selected date in a less(1) window. Similarly, 'R' will view all reminders triggered on
or after the selected date (all non-expired reminders are triggered).

If you want to get a more global view of your schedule, Wyrd will also let you view Remind's formatted
calendar output in a less(1) window. Pressing 'c' will view a one-week calendar that contains the
selected date, while pressing 'C' will view a one-month calendar containing the selected date.

10 Searching for Reminders

Wyrd allows you to search for reminders with MSG values that match a search string. Press '/' to start
entering a (case insensitive) regular expression. After the expression has been entered, press <return>
and Wyrd will locate the next reminder that matches the regexp. Press 'n' to repeat the same search.
Entry of a search string may be cancelled with <esc> or Ctrl-g.

The regular expression syntax is Emacs-compatible.

Note: Sorry, there is no "search backward" function. The search function requires the use of "remind -n",
which operates only forward in time. For the same reason, there is a command to jump forward to the next
reminder, but no command to jump backward to the previous reminder.

11 Other Commands

A list of all keybindings may be viewed by pressing '?'. You can exit Wyrd by pressing 'Q'. If the screen
is corrupted for some reason, hit 'Ctrl-L' to refresh the display.

12 Alarm Strategies

You may wish to generate some sort of alarm when a reminder is triggered. Wyrd does not offer any special
alarm functionality, because Remind can handle the job already. Check the Remind manpage and consider how
the -k option could be used to generate alarms with the aid of external programs. For example, the
following command will generate a popup window using gxmessage(1) whenever a timed reminder is triggered:

remind -z -k'gxmessage -title "reminder" %s &' ~/.reminders &

(A sensible way to start this alarm command is to place it in ~/.xinitrc so that it launches when the X
server is started.)

If you want some advance warning (say, 15 minutes), you can cause Remind to trigger early by setting a
tdelta in the AT clause:

REM Nov 27 2005 AT 14:30 +15 MSG Do something

Alternatively, if you want to generate alarms only for specific reminders, consider using Remind's RUN
command. This process could be easily automated by using the templateN configuration variables described
in Advanced Configuration.

13 Miscellaneous

Remind's TAG specifier may be used to cause Wyrd to give special treatment to certain reminders. If a
reminder line includes the clause "TAG noweight", then Wyrd will not give that reminder any weight when
determining the "busy level" colorations applied to the month calendar. If a reminder line includes the
clause "TAG nodisplay", then Wyrd will neither display that reminder nor give it any weight when
determining the month calendar colorations. The tag parameters are case insensitive.

WARNING: These tag parameters are not guaranteed to interact well with other Remind front-ends such as
tkremind.

14 Usage Tips

Wyrd fills in sensible defaults for the fields of a REM statement, but you will inevitably need to make
some small edits to achieve the behavior you want. If you use Vim, you can make your life easier by
installing the Vim-Latex Suite and then modifying your ~/.wyrdrc to use REM templates like this:

set timed_template="REM %monname% %mday% %year% <++>AT %hour%:%min%<++> \
DURATION 1:00<++> MSG %\"<++>%\" %b"
set untimed_template="REM %monname% %mday% %year% <++>MSG %\"<++>%\" %b"

With this change, hitting Ctrl-J inside Vim (in insert mode) will cause your cursor to jump directly to
the <++> markers, enabling you to quickly add any desired Remind delta and message parameters.

There is a page on Wyrd ⟨https://dianne.skoll.ca/wiki/Wyrd⟩
in the Remind Wiki. This is a good place to look for other usage tips.
