https://tectonic-typesetting.github.io/en-US/learn.html I tried to add a build tool but I can't seem to figure out how to make this work with live preview. I don't understand the difference between a tool class and a tool configuration. I think the preview configurations are frozen so I can't add any new entries. Any help is appreciated! Tectonic also comes with a project format https://tectonic-typesetting.github.io/book/latest/v2cli/init.html. Supporting this would also be a great idea!
I don't know how to make `class=LaTeXLivePreview` on the GUI but adding this entry manually to kilerc worked. [Tool/Tectonic/Default] autoRun=yes checkForRoot=no class=LaTeXLivePreview command=tectonic from= jumpToFirstError=yes options=-X compile %dir_base/%source --synctex --outdir %dir_target --print to=pdf type=Process
