Part of: https://github.com/NixOS/nixpkgs/issues/108938 meta = with stdenv.lib; is a widely used pattern. We want to slowly remove the `stdenv.lib` indirection and encourage people to use `lib` directly. Thus let’s start with the meta field. This used a rewriting script to mostly automatically replace all occurances of this pattern, and add the `lib` argument to the package header if it doesn’t exist yet. The script in its current form is available at https://cs.tvl.fyi/depot@2f807d7f141068d2d60676a89213eaa5353ca6e0/-/blob/users/Profpatsch/nixpkgs-rewriter/default.nix

|
|
GROMACS is a versatile package to perform molecular dynamics,
|
|
i.e. simulate the Newtonian equations of motion for systems
|
|
with hundreds to millions of particles.
|
|
|
|
It is primarily designed for biochemical molecules like
|
|
proteins, lipids and nucleic acids that have a lot of
|
|
complicated bonded interactions, but since GROMACS is
|
|
extremely fast at calculating the nonbonded interactions (that
|
|
usually dominate simulations) many groups are also using it
|
|
for research on non-biological systems, e.g. polymers.
|
|
|
|
GROMACS supports all the usual algorithms you expect from a
|
|
modern molecular dynamics implementation, (check the online
|
|
reference or manual for details), but there are also quite a
|
|
few features that make it stand out from the competition.
