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

'' GNU Ocrad is an OCR (Optical Character Recognition) program based on
|
|
a feature extraction method. It reads images in pbm (bitmap), pgm
|
|
(greyscale) or ppm (color) formats and produces text in byte (8-bit)
|
|
or UTF-8 formats.
|
|
|
|
Also includes a layout analyser able to separate the columns or
|
|
blocks of text normally found on printed pages.
|
|
|
|
Ocrad can be used as a stand-alone console application, or as a
|
|
backend to other programs.
