omm

✨ Overview

omm (stands for "on-my-mind") is a keyboard-driven task manager for the command line.

🤔 Motivation

The fundamental idea behind omm is that while we might have several tasks on our to-do list — each with its own priority — we typically focus on one task at a time. Priorities frequently change, requiring us to switch between tasks. omm lets you visualize this shifting priority order with a very simple list interface that can be managed entirely via the keyboard.

💾 Installation

homebrew:

brew install dhth/tap/omm

go:

go install github.com/dhth/omm@latest

Or get the binaries directly from a release. Read more about verifying the authenticity of released artifacts here.

⚡️ Usage

TUI

omm's TUI is comprised of several views: 4 lists (for active and archived tasks, one for task bookmarks, and one for prefix selection), a context pane, a task details pane, and a task entry/update pane.

Active Tasks List

As the name suggests, the active tasks list is for the tasks you're actively working on right now. It allows you to do the following:

• Create/update tasks at a specific position in the priority list
• Add a task at the start/end of the list
• Move a task to the top of the list (indicating that it takes the highest priority at the moment)
• Move task up/down based on changing priorities
• Archive a task
• Permanently delete a task

Archived Tasks List

Once you're done with a task, you can archive it, which puts it in the archived tasks list. It's more for historical reference, but you can also unarchive a task and put it back in the active list, if you need to. You can also permanently delete tasks from here.

Context Pane

For tasks that need more details that you can fit in a one line summary, there is the context pane. You add/update context for a task via a text editor which is chosen based on the following look ups:

• the "--editor" flag
• $OMM_EDITOR
• "editor" property in omm's toml config
• $EDITOR/$VISUAL
• vi (fallback)

Task Details Pane

The Task Details pane lets you see all details for a task in a single scrollable pane.

Task Entry Pane

This is where you enter/update a task summary. If you enter a summary in the format prefix: task summary goes here, omm will highlight the prefix for you in the task lists.

Tweaking the TUI

The list colors and the task list title can be changed via CLI flags.

omm \
    --tl-color="#b8bb26" \
    --atl-color="#fb4934" \
    --title="work"

omm offers two modes for the visual density of its lists: "compact" and "spacious", the former being the default. omm can be started with one of the two modes, which can later be switched by pressing "v".

omm --list-density=spacious

This configuration property can also be provided via the environment variable OMM_LIST_DENSITY.

Compact mode:

Importing tasks

Multiple tasks can be imported from stdin using the import subcommand.

cat << 'EOF' | omm import
orders: order new ACME rocket skates
traps: draw fake tunnel on the canyon wall
tech: assemble ACME jet-propelled pogo stick
EOF

Tip: Vim users can import tasks into omm by making a visual selection and running :'<,'>!omm import<CR>.

Adding a single task

When an argument is passed to omm, it saves it as a task, instead of opening up the TUI.

Configuration

omm allows you to change the some of its behavior via configuration, which it will consider in the order listed below:

• CLI flags (run omm -h to see details)

• Environment variables (eg. OMM_EDITOR)

• A TOML configuration file (run omm -h to see where this lives; you can change this via the flag --config-path)

  Here's a sample config file:

  db_path      = "~/.local/share/omm/omm-w.db"
  tl_color     = "#b8bb26"
  atl_color    = "#fabd2f"
  title        = "work"
  list_density = "spacious"
  show_context = false
  editor       = "vi -u NONE"

Outputting tasks

Tasks can be outputted to stdout using the tasks subcommand.

🤔 Tips

These are some tips to improve your experience of using omm:

• Set up discrete instances of omm if you need to. You can do so by referencing a different config file (which points to a unique database) for each instance, or by directly using --db-path flag. Eg. an omm instance for personal tasks, and another for work. Set up as many omm instances as you need.
• Use omm updates to stay up to date with omm's latest features/changes.

🔐 Verifying release artifacts

In case you get the omm binary directly from a release, you may want to verify its authenticity. Checksums are applied to all released artifacts, and the resulting checksum file is signed using cosign.

Steps to verify (replace the version in the commands listed with the one you want):

1. Download the following files from the release:

   • omm_0.5.0_checksums.txt
   • omm_0.5.0_checksums.txt.pem
   • omm_0.5.0_checksums.txt.sig

2. Verify the signature:

   cosign verify-blob omm_0.5.0_checksums.txt \
       --certificate omm_0.5.0_checksums.txt.pem \
       --signature omm_0.5.0_checksums.txt.sig \
       --certificate-identity-regexp 'https://github\.com/dhth/omm/\.github/workflows/.+' \
       --certificate-oidc-issuer "https://token.actions.githubusercontent.com"

3. Download the compressed archive you want, and validate its checksum:

   curl -sSLO https://github.com/dhth/omm/releases/download/v0.5.0/omm_0.5.0_linux_amd64.tar.gz
   sha256sum --ignore-missing -c omm_0.5.0_checksums.txt

4. If checksum validation goes through, uncompress the archive:

   tar -xzf omm_0.5.0_linux_amd64.tar.gz
   ./omm
   # profit!
