Sigi

Sigi is an organizing tool and no-frills stack database.

It's primarily intended for you to use as extra memory. Use it to organize your tasks, groceries, or the next board games you want to play.

Sigi is also a stack-management tool. It can be used as disk-persistent stack memory, for example, in a shell script or in Rust code. (And more languages in the future!)

Motivation

Sigi is the Chamorro word for continue. I hope it will help you to plan more, forget less, get things done, and relax. 🌴

There's a limit to human memory, and remembering things uses up willpower. I like working at a command line, and wanted a tool to free me up from trying to juggle tasks and ideas.

I also just like stacks, and stack-based languages like Forth and Factor are a joy to play with.

Examples

Sigi as a to-do list

Sigi can understand do (create a task) and done (complete a task).

$ alias todo='sigi --stack todo'

$ todo do Write some code
Creating: Write some code

$ todo do Get a drink
Creating: Get a drink

$ todo do Take a nap
Creating: Take a nap

$ todo list
Now: Take a nap
  1: Get a drink
  2: Write some code

$ sleep 20m

$ todo done
Completed: Take a nap

It's best to use sigi behind a few aliases with unique "stacks". You should save these aliases in your ~/.bashrc or ~/.zshrc or whatever your shell has for configuration. Sigi accepts a --stack flag that indicates a unique list. You can have as many stacks as you can think of names.

Forgot what to do next?

$ todo
Now: Get a drink

Not going to do it?

$ todo delete
Deleted: Get a drink

Sigi as a save-anything list

Extending the alias idea, you can use sigi to store anything you want to remember later.

$ alias watch-later='sigi --stack watch-later'

$ watch-later add One Punch Man
Creating: One Punch Man

$ alias story-ideas='sigi --stack=story-ideas'

$ story-ideas add Alien race lives backwards through time.
Creating: Alien race lives backwards through time.

Sigi as a local stack-based database

Sigi understands the programmer-familiar push (create an item) and pop (remove an item and return it) idioms.

Using the --quiet (or -q) flag is recommended for shell scripts, as it leaves out any leading labels or symbols.

TODO: Need an example, maybe a reverse polish notation calculator in bash?

Installing

Command-line interface (CLI)

Currently the best way to install sigi is through the Rust language package manager, cargo:

cargo install sigi

Instructions on installing cargo can be found here:

• https://doc.rust-lang.org/cargo/getting-started/installation.html

In the future I plan to distribute sigi through more package managers.

Library

Sigi is available as a Rust library via crates.io.

It is still in active, unstable development, so I suggest not doing anything ambitious until stable versions (i.e. >= 1.0) become available.

In the future I plan to provide wrappers through other languages. Also, the implementation language is possibly subject to change.
