harsh is habit tracking for geeks. A minimalist, command line tool for tracking and understanding your habits.
Succinctly: it's quick and gets out of your way. And gives you excellent visibility on your habits.
There're 3 commands: ask, log, and todo.
(and two subcommands log stats and log check <match term>)
Designed for simplicity, visibility, and longevity, harsh uses simple text files for tracking that are human-grokable and editable in your favourite text editor. It's simpler, less messy, and more portable than commercial or mobile applications and less fussy to manage than emacs habit tracking (imho). While quantified individual tracking is exhaustive, important habits get lost in the data deluge, so this provides deliberate, explicit, habits to track and progress.
It's written in Go and adds features and fixes on top of habitctl (its
inspiration) such as skips, streak break warnings, stats, quantities, and as of
0.10.0 targets over intervals (like 3 times in a week). If you're a geek,
I think you'll like it. Despite trying an exhaustive number of habit trackers,
this was what worked for me. YMMV. If you're interested in why I wrote it,
there's a launch post about my motivations on my
blog.
My biggest hope that it helps you get done what you're trying to get done in your life and live a better one.
harsh is available on OSX (and via homebrew), Linux (also as a Snap and homebrew), FreeBSD, OpenBSD, and Windows. A specific goal was increasing uptake and adoption of a portable, command line, text-based approach to habit tracking. harsh also supports ARM architectures for OSX (M1, M2, and M3 chipped Macs and Linux and BSDs) as of 0.8.8. Binaries for FreeBSD and OpenBSD are also available as of 0.8.23.
Homebrew tap (Mac and Linux):
$ brew install wakatara/tap/harsh
(this will also nicely alert you of updates when you brew update)
Snap (Linux only):
$ sudo snap install harsh
(you'll also get alerted when there are updates)
If you're not using a package manager, by far the easiest way to install harsh and get started is to use this one-line bash command if you're on OSX or Linux:
curl -sSLf https://raw.githubusercontent.com/wakatara/harsh/master/install.sh | shThe script downloads the latest release directly from github, verifies it
cryptographically, and then moves the executable to usr/local/bin ready for
immediate use on the command line.
You may prefer a direct Go install if you have a working Go environment and Go 1.14+.
go install github.com/wakatara/harsh
from the command line. Unlike a package manager like brew or snap, you won't get informed of new version releases.
Alternatively, you can download the pre-compiled binaries from
the releases page
and copy to the desired location (/usr/local/bin recommended),
making sure it's in your $PATH.
If you want to build from source cause you like that sort of thing, follow these steps:
Clone:
$ git clone https://github.com/wakatara/harsh
$ cd harsh
Get the dependencies:
$ go get ./...
Build:
$ go build -o harsh .
Verify it works:
$ ./harsh --version
You can then move the file to the desired location in your $PATH.
When you run harsh ask for the first time, it will set up the required files:
$ harsh ask
Welcome to harsh!
Created /Users/daryl/.config/harsh/habits This file lists your habits.
Created /Users/daryl/.config/harsh/log This file is your habit log.
What? No habits yet?
Open the habits file and edit the habit list using a text editor.
Then run `harsh ask` to start tracking
'harsh todo` will show you undone habits for today.
`harsh log` will show you a consistency graph of your efforts
(trust me, it looks way cooler looking over time)
Happy tracking! I genuinely hope this helps you get better.
On OSX and Linux based systems, the habits and log files will be under
~/.config/harsh/. On Windows, you can find the files under %APPDATA%\harsh.
Alternatively, you can set a different directory using the HARSHPATH environment variable.
Ubuntu's snap overrides (sensible) defaults and forcibly places harsh's config and log files in ~/snap/harsh/current/. If you snap remove the harsh app, snap's uninstaller will nuke your config and log files with the sandbox and you may lose your config and log data if it's not backed up (please always exercise a good backup regime). For this reason, we highly recommend snap users set the HARSHPATH env variable to ~/.config/harsh/ and move config and log files there right after installing to protect them. Or never uninstall harsh. π |
Open the habits file in your text editor of choice (nano, vim, VS Code, Sublime, or emacs).
You'll see an example file like this:
# This is your habits file.
# It tells harsh what to track and how frequently in days.
# 1 means daily, 7 means weekly, 14 every two weeks.
# You can also track targets within a set number of days
# For example, Gym 3 times a week would translate to 3/7
# 0 is for tracking a habit. 0 frequency habits will not warn or score.
# Examples:
! Dailies
Gymmed: 1
Bed by midnight: 1
! Weeklies
Gymmed: 3/7
Called Mom: 7
! Monthly+
Did Finances: 30
New Skill: 90
! Tracking
Too much coffee: 0
Used harsh: 0
A big change starting in version 0.10.0, harsh now allows you to pick a target
number of times you want to perform a habit over a set interval of time (in
days). Examples would be 3/7 for 3 times a week, 2/30 for twice a month etc
etc.
So, for example, wanting to make it to the gym 3 times a week (ie. 7 days) would translate into a line in the habit file like:
Gymmed: 3/7
You can also simply pick a number of days you want to repeat a habit (also, for backwards compatibility with older habit files).
Note that this uses a rolling window of days than actual week delimiters (mostly because having hard start of week, month, and quarter breaks broke the point of consistency graphs when I implemented it. This is much nicer. Trust me.).
If it's not obvious from the example file, habits can have any character that is
not a : as that delimits the period. We also use : as the separator in log
files as well for easy parsing.
Headings are denoted by a "!" at the start of a line and allow you to categorize habits visually (useful if you have a lot of them).
Comments can go in the habits file by starting a line with "#" and are not parsed by the program.
The real trick of tracking is figuring out what habits you want to track building or breaking. Too many, you'll fail. Too few, and the app loses its edge. Too short-term, you feel good but fail on longer-term objectives.
If you're getting started, try 5-8 and mix short term and long term and see how you go. Tracking your habits is strangely also a habit you need to build. There're no right answers, but if this is new, focus on foundational keystone habits that will feed future ones. If you're coming into this cold, I'd also recommend a good read of James Clear's Atomic Habits.
Here are some ideas of what to track:
- Went to bed on time
- Got X hours of sleep
- Inbox zero
- Practiced Italian
- Morning Pages
- Blogged
- Studied astrophysics
- Socialized
- Stuck to budget
- Coded
- 2 coffees only
- Thanked someone
- Went for a walk
- Told SO they're amazing
Simply run harsh ask regularly, specify whether you did the habit from the
prompt on a particular day (or needed to skip the habit for some reason - eg.
could not clean apartment because you were away for week), and get pretty
graphs!
harsh ask allows you to pick between [y/n/s/β] which is yes/no/skip/don't
answer right now. CTRL-c breaks you out of the ask cycle at any point and
returns you to your prompt.
As of version 0.9.0, to support longer term pattern tracking (and fallible
memories), you can follow any of the y | n | s options with an optional typed
@ symbol to then denote a quantity you want to track for the daily habit
(example: number of words written, km's run, pullups performed etc), and/or an
optional typed # symbol for a comment. Primarily for analysis at a later date.
The log stats subcommand will also now total up any amounts you've entered for
a habit and show you the total along with your streaks, skips, breaks, and days
tracked.
An example of how to use this for a habit like PullUps might be:
$ harsh ask
2024-01-05:
Dailies
PullUps β β β ββ β β β β βββββββββββ β β β[y/n/s/β] y @ 15 # Crushed workout today!
This will, besides adding y to the log file, also record "15" and the comment
"Crushed workout today" to your log file. The feature is backwards compatible
even with older log files so even if you don't use it, you're alright. 0.9.0
will also parse older logs. You must use a valid number in the @ position and
the only other caveat is if you use both an @ and # in your prompt response,
the @ must come before the #. The only disallowed character in a prompt is
: as it is used as a field separator in the log files (to make for easy
importing and parsing by spreadsheet and other tools like pandas.)
The annotating features are primarily for analysis at a later date to help uncover patterns between events, reasons you may have written a comment, and good or bad knock-on effects.
Personally, I use comments sparingly and to denote why you had to skip, broke
a consistency chain with an n, or for when you're trying to figure out
something notable on a day so when you look back you can see why habit X may
or may not have succeeded.
harsh log The consistency graph shows your last 100 days.

Yesterday's score: 88.3%
The sparkline at the top give a graphical representation of each day's score.
The score at the bottom specifies how many of your habits you met that previous day of total possible and removes any you may have skipped from the calculation.
Run harsh log stats gives an analysis of your entire log file and a quantified
idea of days you've been on streak, how many days you broke your consistency
chain, and how many days you may have skipped -- as well as the total number of
days you've been tracking a particular habit for (note: I swap out my file every
year, but at least one person wanted this feature to track over 800+ days of log
files they'd converted from another app.). It's also nicely coloured to help
visually separate the information.
In particular, when you've been tracking for longer than 100 days (the visual length of the consistency graph), you can get summary stats for your entire log (tbh, I did not think this was useful until I implemented it. I was wrong.). This can be surprisingly useful to see longer trends quantified.

As you can see here, I need to work on sleep more than anything, but digging down on these stats I shocked myself at skipped and breaks in workouts (covid vaccine related in some cases), and how I need to rethink how some of these were set up or I'm doing them (running, blogging etc.). The point is not how terrible I am, but that looking into the numbers revealed patterns (sleep, affects workouts, running, and TIL - today I learned - rather terribly). YMMV.
Run harsh log check <search term> gives a slightly more in depth analysis of
individual habits in conjunction with your topline aparkline. The idea here is
that you can examine individual habits graphically against your topline to see
if there are patterns of correlation between the variation in an individual
habit and your overall daily score over time.
Say you expect there's a close correlation between you not getting good sleep
and your habits generally falling from a state of grace. It's easy to check with
a log check and any string you type from your habits. In my case, I have
a habit around getting to bed on time and getting a solid 7 I call Bed by 11+Slept 7h+. I can just use the handy bed as a short match term for the habit
and get the result.
$ harsh log check bed
ββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββ
Bed by 11+Slept 7h+ β β β ββββ βββ ββ β βββ ββ’ ββββββββ ββββ ββββ
As we can see, there is a pretty close correlation here to not getting enough sleep (or going to bed too late) and me hitting all my daily habits.
A done habit gives you a nice bright β on the consistency graph line. It's done.
Additionally, the app checks in future days if you are still within the "every
x days" period of performing the habit by drawing a dimmer β after the done
marker to let you know you've satisfied the requirement for that habit.
Sometimes, it's impossible to exercise a habit cause life happens. If cleaning
the house is a habit you want to exercise, but you happen to be away on
a business trip, that is an impossibility. And sometimes, you decide to skip and
push the habit to the next period (or a simple day or so). Skips being selected
(s in the prompt) allows this to happen. A skip is denoted by a bright β’.
Much like satisfied habits where you've performed them once in the period,
"skipified" habits let you know you're still withing the calculated grace period
of the skip with a lighter dot Β·.
harsh also has a warnings feature to help flag to you when you're in danger of breaking your consistency graph. Harsh will give you a warning by showing a "!" symbol in your upcoming habits.
For habits of every less than 7 days period, you get a warning sigil on the day
the chain will break if you do not perform the habit. For a week or longer,
you'll start to see a warning sigil of 1 + days/7 rounded down (eg. so,
2 weeks' warning would get you the sigil 3 days ahead of breaking the chain
etc.).

NAME:
Harsh - habit tracking for geeks
USAGE:
harsh [global options] command [command options] [arguments...]
VERSION:
0.10.0
DESCRIPTION:
A simple, minimalist CLI for tracking and understanding habits.
COMMANDS:
ask, a Asks and records your undone habits
log, l Shows graph of habits
todo, t Shows undone habits for today.
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
--help, -h show help (default: false)
--no-color, -n no colors in output (default: false)
--version, -v print the version (default: false)
As you increasingly use harsh for tracking, you'll inevitably end up making
small errors in your log file or will want to edit your config file. While
people have suggested adding a harsh config command to the app, this feels
like overkill for the intended audience (geeks) but you can get the same effect
through using aliases.
As a simple quality of life improvement, add the following to your bash,
zsh, fish (what I use), or shell of choice:
alias h="harsh"
alias hc="nvim ~/.config/harsh/habits"
alias hl="nvim ~/.config/harsh/log"For me, this equates to me ending up typing h log for the graph, h ask etc
etc. When I need to edit the log file because I was a bit too itchy with my
trigger finger (or decide I should add a note), hl is my friend.
New from 0.8.22: if you are logging the output of harsh log stat and other
features which contains colour codes, you can instead use --no-color flag via
harsh --no-color [command] (or harsh -n [command]) to suppress colourized
output. This is also very helpful in n/vim with the :.! harsh -n log stats
command stanza to record harsh's output to n/vim's buffer to augment your
weekly, monthly, or daily tracking (learned that vim snippet from the feature
requester!).
Much like the above feature of accessing config and log files, you can alias
harsh -n in your shell if you prefer to suppress all colour output coming from
all harsh commands.
