- Project mention: Show HN: Tascli, a command line based (human) task and record manager | news.ycombinator.com | 2025-12-06
Feels like a project covering some of the same ground as task warrior [0], which I've used on and off over the years. The main thing I've appreciated is integration with various tools - I had access in both vimwiki and the macOS task bar for a while which was nice - but all these tools miss the key thing that stops me using them all the time: integration with tools on my phone. It's great having cli access to tasks and in other places, but without ubiquity, given the way I work, it might well just be another place that ideas of tasks I need to do go to die.

CLI11
CLI11 is a command line parser for C++11 and beyond that provides a rich feature set with a simple and intuitive interface.
For starters, DeadLock should take input from the command-line, therefore, a parser is required. Hence, I am going to use CLI11 to add my custom parameters and take user input from the terminal. Moreover, I will be using {fmt} to stylize and colorize the terminal outputs.
