A general-purpose low-latency application to serve cognitive tasks, built with egui.
The most reliable way to install CogTask is by installing Cargo through rustup and compiling the binaries locally.
Install cargo: curl https://sh.rustup.rs -sSf | sh
Build stable binaries from crates.io: cargo install cog-task
OR Build unstable binaries from github: cargo install --git https://github.com/menoua/cog-task-rs
This crate installs two binaries -- cog-launcher and cog-server.
cog-launcher: A launcher that provides a graphical interface to find and load tasks from disk.
cog-server /path/to/task: Used to run a specific task by providing the path to its directory. cog-launcher runs this binary when starting a task, so make sure both binaries are in the same directory.
Version 0.2.0 has gone through a massive overhaul, transitioning from the GUI framework of iced to egui. The transition was done to solve a screen update skipping issue (which it did). There have been other pros and cons too. Text and widget styling is (much) more difficult in egui. egui's Glow backend supports image/SVG. Separating the view and update calls allowed redesigning block architecture (the dependency graph) into an action tree. This change makes it very difficult to design a buggy task, and significantly simplifies task definition style. It slightly limits the task design flexibility, but it's worth it. This change also comes with an increased overhead since update/view calls traverse the entire active subset of the tree, instead of jumping to the end nodes. However, the tree overhead is generally low compared to action-specific overheads, so that's not a huge deal.
