About dLine

dLine is an open-source command-line calendar tool for terminal users, and the project describes it as designed for developers. It shows the current month's events with color-coded categories, displays a plain monthly calendar for any chosen month, and counts workdays between two dates. Users can add events directly or interactively, manage several calendars, and import public holidays.

In its default dynamic view, background processes look for unresolved deadlines up to six months ahead and overdue deadlines up to one month back. They also create pop-up reminders for events within 48 hours. Calendar data can be updated from APIs automatically, and the timing of these processes can be set in a .dlinerc file. On first launch, the tool asks for a region in order to fetch relevant holidays, and this can be changed later. The source excerpt does not state which operating systems are supported, and it does not describe pricing.
