• Keeps files updated and organised
• Automatic download of module files
• Automatic update of module files when files are reuploaded
• System notifications
• System-based dark/light mode
• System tray icon
• Telegram integration

Getting Started

Installation

Unsigned standalone executables for Windows, macOS and Linux are available from releases.

Note: Please read through installation introduction for the respective operating systems below.

Windows

Tested on Windows 10 Home Version 10.0.19044 Build 19044

Your anti-virus software like Windows Defender may prompt that lominus.exe as a false positive. You may need to make an exception for it.

This occurs because the app is unsigned amongst other reasons regarding Go executables which you may find out more here. Signing it requires a valid certificate which is payable.

macOS

Tested on M1 MacBook Air 2020 macOS Monterey Version 12.1

You may receive the prompt

“Lominus” is damaged and can’t be opened. You should eject the disk image.

or

The app is from an unidentified developer.

This happens because the app is unsigned. Signing it requires a valid certificate which requires a valid Apple Developer Program membership.

To enable exception for this app

xattr -cr [filepath]

where [filepath] is the path to the .dmg file.

Linux

Tested on Ubuntu Focal 20.04.2 LTS and Arch

Download and extract the tarball

tar -xf [filename].tar.xz

Install the application

sudo make install

Building

Prerequisites

1. Golang >= 1.18

2. gcc

3. gtk3 and libayatana-appindicator3-dev (Linux)

   • For Debian and Ubuntu, you may install these via

     sudo apt-get install gcc libgtk-3-dev libayatana-appindicator3-dev

   • If you are on Linux Mint, you will require libxapp-dev as well.

4. libxxf86vm-dev might help if Lominus keeps crashing on startup

Build

1. Ensure GOPATH is set in your system env

   export GOPATH=$HOME/go

2. Install dependencies in the directory where you cloned

   go install

3. Install fyne

   go install fyne.io/fyne/v2/cmd/fyne@latest

4. Ensure that your system PATH contains $GOPATH/bin before building.

   export PATH=$GOPATH/bin:$PATH
   fyne package

API

Lominus can also be used as an API. Please visit documentations for more details. However, do note that the documentations are lacking after v2.0.0 update due to lack of time :(. This should be fixed in due time.

Example: Retrieving your modules

package main

import (
    "log"

    "github.com/beebeeoii/lominus/pkg/api"
    "github.com/beebeeoii/lominus/pkg/auth"
    "github.com/beebeeoii/lominus/pkg/constants"
)

func getCanvasModules() {
    canvasToken := "your-canvas-token"

    modulesReq, modReqErr := api.BuildModulesRequest(canvasToken, constants.Canvas)
    if modReqErr != nil {
        log.Fatalln(modReqErr)
    }

    modules, modulesErr := modulesReq.GetModules()
    if modulesErr != nil {
        log.Fatalln(modulesErr)
    }

    for _, module := range modules {
        log.Println(module.ModuleCode, module.Name)
    }
}

Integrations

Telegram

Telegram can be used to receive notifications for things such as new grades releases.

Setting up

1. Retrieve your bot token via BotFather.

2. Retrieve your Telegram user ID. The simplest way is via UserInfoBot.

3. Copy and paste the bot token and your Telegram user ID in Lominus, under the Integrations tab.

4. Save and you should receive a test message from your bot.

Ensure that the bot is able to message you by dropping it a message.
