wireshark used to use autotools, but instead we now use cmake. The
change alone brought to light a few missing required dependencies.
Additionally, wireshark was using gtk2 and qt4, so that has changed to
gtk3 and qt5.
This doesn't change any defaults; I suspect that dropping gtk2 support
would annoy some people so I didn't want to do that without asking
around first.
Putting information in external JSON files is IMHO not an improvement
over the idiomatic style of Nix expressions. The use of JSON doesn't
add anything over Nix expressions (in fact it removes expressive
power). And scattering package info over lots of little files makes
packages less readable over having the info in one file.
termite broke when upgrading Gnome, as this removed a dependency from
the tree. I packaged this dependency (vte-ng) based upon the work of
@globin in https://github.com/NixOS/nixpkgs/issues/22026.
https://nixos.org/nixpkgs/manual/#r-packages contains a method for
setting up an R environment with a specific set of libraries, and it
creates an R wrapper which points R to those libraries.
The package RStudio relies on the standard R package, which then
cannot access any of the libraries specified in a custom R
environment. While one may easily use pkgs.rstudio.override to change
rstudio's R dependency to the custom R environment, this accomplishes
nothing because while RStudio runs the correct R wrapper it clears out
the environment variable R_LIBS_SITE - and so it is still unable to
use any of those packages.
In order to work around this problem, these changes allow the user to
optionally modify rstudio's wrapper to set environment variable
R_PROFILE_USER to an R script which sets R's .libPaths(..) to point to
the same libraries; that script is generated from R_LIBS_SITE in the R
wrapper.
By default, this change has no effect. If R is overridden to
something else, and if useRPackages is changed from its default of
false, then the change described above is made; for instance:
{
packageOverrides = pkgs: let self = pkgs.pkgs; in
rec {
rEnv = pkgs.rWrapper.override {
packages = with self.rPackages; [
dplyr ggplot2 e1071 rpart reshape
];
};
rstudioEnv = pkgs.rstudio.override { R = rEnv; useRPackages = true; };
};
}
