Nestable

A terminal based app for taking nested notes.

** WARNING: Nestable is currently in an experimental state. Don't expect it to be stable for regular use until v1.0 **

Overview

Nestable is a terminal based app for nesting notes within each other. It is delivered as a single executable binary with batteries included. It stores notes locally in a single SQLite file. It has subcommands to help edit notes, find notes, and export notes.

Features

• Single file executable - easy to install and remove, Nestable is self contained in a single file executable (thanks Go!)
• Single file for all notes - all notes and files are stored in a single file database (thanks SQLite!). Easy to back up and transport.
• Use any editor that can be launched from the commandline (vi/mate/vscode)
• Easy to find notes with fuzzy find feature (thanks Go FuzzyFinder!)

Installation

Download Nestable from the releases. Place it in a directory in your PATH environment variable, such as /usr/local/bin.

Want to build it from source? If you have all the build dependencies, you can run make inside the repo.

Setup

Customize your text editor

Nestable can be configured to work with any text editor launchable from the command line. Nestable keeps track of your desired editor by looking up a config value in the nest database. You can view the current value with:

nst get-config -key editor

By default, the editor is set to vi.

You can change it with nst set-config -key editor -val $MYEDITOR

If the database doesn't have a value for the editor, or it is set to an empty string, Nestable will defer to the EDITOR environment variable for which editor to run.

To see which editor is currently configured

Note: Nestable requires that the command used to launch the editor must wait to exit until the file is closed. For example, TextMate has a CLI command mate that accepts an argument -w that enables this behavior. Without -w, mate will return immediately before the file is done being edited and fail to capture the changes in the database. Nestable is aware of this nuance and appends the necessary args for the following supported editors:

1. mate (Textmate)

Nest (Database File)

The database file that stores notes is called a "nest". The nest will have a .nest suffix. The nest is actually a SQLite3 database that stores all notes and attachments in a single file.

Nestable will look in the current directory for the hidden file .notebook.nest. If it cannot find this file in the current directory, it will default to the file ~/.notebook.nest. If this file does not exist, an error will be returned.

You can override this behavior by providing one of these options:

• nst -n [path/to/my.nest] - provide this top level CLI argument to specify a location. If the location is omitted, an interactive fuzzy finder will be displayed to allow selecting all detected nest files. Overrides NESTABLE_NEST environment variable when provided.
• NESTABLE_NEST - set this environment variable to the path to the desired nest

nst ex	export notes to markdown document
nst v	select a note to view
nst w	server web version of notes
nst wc	word cloud
nst b	browse all notes
nst gc -key <key>	get a configuration value

nst

Initialize nest

Before you can start writing notes, you need to initialize your nest:

nst i(nit)

This will create an empty nest at ~/.notebook.nest.

Creating and editing a note

To quickly add a new note: nst n(ew)

To quickly edit an existing note: nst e(dit) [id]

If the optional id value is not specified, Nestable will display an interactive list to select the desired note. By default, the last modified note will be selected.

Viewing a note

The view subcommand allows you to view a note without leaving the terminal.

To select a note to view, nst view opens a fuzzy finder to locate a note for viewing. By default, the last modified note will be selected.

The fuzzy finder only allows searching through the first line of the note. To search through the full text of a note, use the full text search option.

nst view -s <search-term>

The results of the full text search will be presented in a fuzzy finder list to select the desired one. The <search-term> supports a number of matching operations. Refer to the SQLite3 FTS5 query syntax documentation for more details.

Web Browse

To view notes in a web browser:

nst w(eb)

By default runs on localhost:3000.

Word Cloud

Sometimes you aren't sure what you're looking for. The word cloud allows you to view all the terms ranked by appearances. Select a term to view all notes that mention it:

nst w(ord)-c(loud)

Browsing notes

To browse all notes: nst b(rowse) displays all notes in a outline in the terminal.

Exporting notes

You can export all notes in the current notebook with:

nst ex(port)

This will render all of the notes, in order of note ID, in a markdown format. A table of contents will be generated at the top of the document, followed by each note. Each note will have a header followed by the body of the note.

Configuration

Each nest can track configuation values in a key-value database. To select a config for viewing:

nst g(et-)c(onfig)

You can also specify a config:

nst g(et-)c(onfig) -key <config-key>

You can set a config with:

nst s(et-)c(onfig) -key <config-key> -value <config-value>

FAQ

Who are the inspirations?

• nb - for terminal based note taking
• Workflowy - for nested note taking concept
• Fossil - SQLite based SCM with advanced features

What are the design goals and principles?

• Local first - notes are stored locally first. No backup to an external service occurs unless the user explicitly configures it.
• Optimal for small bits of work - need to jot down a single sentence? Since notes are not files, there is less anxiety about cluttering up a file system.
• Fast - writing and reading notes should be fast. Searching for notes should be fast. Indexing or back up operations should never get in the way of capturing a thought.
• Single file database - notes are kept in a single file. This simplifies backup and sharing of notes. This emboldens the user to store many small bits of data.
• Relational notes - notes maintain relationships between each other through various mechanisms (tags) to build a knowledge graph.
• Terminal first - the primary interface is in the terminal. This makes it great for developer workflows.
• Batteries included - whenever possible, all functionality should derive from the single executable. The editor is the only external dependency and a default editor may be embedded in the future to mitigate that.
• Interactive first - user interfaces are interactive by default. This makes learning the tool much faster since you don't have to remember a bunch of CLI arguments to start using it.
• Extensible - there's no definitive way to use it. Various features leave the door open for creative use cases.
