latex-dev(1) General Commands Manual latex-dev(1)
NAME
latex-dev, pdflatex-dev, xelatex-dev, lualatex-dev, dvilualatex-dev,
platex-dev, uplatex-dev - release candidate LaTeX testing
SYNOPSIS
latex-dev [options] [&format] [ file [ more-input ] | [ \more-input ]
DESCRIPTION
These -dev executables are made so that anyone interested can easily
help test upcoming LaTeX releases. They correspond to new formats which
have been tested by the LaTeX team for stability and usability. They
are not arbitrary development snapshots; more like release candidates
and checkpoints.
Testing by as many users as possible is desired and requested. Simply
replacing the regular engine (e.g., pdflatex) with the -dev engine name
(pdflatex-dev) in your invocations is all that should be needed. No
changes to source documents should be required.
The lualatex-dev format is built with the luahbtex engine, the LuaTeX
variant with HarfBuzz (https://en.wikipedia.org/wiki/HarfBuzz)
supported for glyph shaping.
The latest ltnews document present in latex-dev describes the changes
present in -dev compared to the previous official release. E.g., if the
official release has a document ltnews42.pdf, then look for
ltnews43.pdf in the -dev tree.
OPTIONS
See tex(1) for details of command-line parsing.
