Tutorials

Lessons that take you through aless from the start, one step at a time, with what aless shows at every step.

Start here if you have not used aless before. Each tutorial is a walk you can follow to the end in a few minutes, on a file you download first, and it shows what aless prints at every step. If you already have a task in mind, the how-to guides get to it sooner.

Look around a file in the viewer

Open a file in aless, move through it, fold it, search it and copy a path, then change it on disk and see aless keep your place.

Ask a file questions from a script

Use aless without its viewer, as a script or an agent does, to outline a file, read the value at a path, find nodes, turn a line and column into a path, and read an error.
