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

|
DRAT-trim is a satisfiability proof checking and trimming
|
|
utility designed to validate proofs for all known satisfiability
|
|
solving and preprocessing techniques. DRAT-trim can also emit
|
|
trimmed formulas, optimized proofs, and TraceCheck+ dependency
|
|
graphs.
|
|
|
|
DRAT-trim has been used as part of the judging process in the
|
|
annual SAT Competition in recent years, in order to check
|
|
competing SAT solvers' work when they claim that a SAT instance
|
|
is unsatisfiable.
|
|
|
|
This package also contains the related tool LRAT-check, which checks a
|
|
proof format called LRAT which extends DRAT with hint statements to speed
|
|
up the checking process.
