Tectonic

tectonic is a modernized, alternative TeX engine. Most features of texlab work out of the box when using tectonic. To compile documents through texlab, you need to change the configuration. See tectonic --help for more information about the flags.

Hint:

Please make sure to set texlab.build.pdfDirectory and texlab.build.auxDirectory to the configured output directory (see --outdir argument).

Also, --keep-intermediates is recommended because they allow texlab to find out the section numbers and show them in the completion. Without the --keep-logs flag, texlab won't be able to report compilation warnings.
