This commit describes the "->" notation for dependency types in
greater detail, and uses g++ to provide examples of all six cases
(although the host->target and target->target examples are a bit
artificial).
It also adds three more rows to the table for the "->*" dependency
types for non-compiler-like packages; these dependency types were
already present in the documentation but the "*" was not really
explained.
Lastly, this commit adds a hyperlink to the table from the place where
it is mentioned in the "specifying dependencies" chapter.
Allows restricting patches to a specific subdirectory, à la
`git diff --relative=subdir`.
This cannot be done (cleanly) currently because the `includes` logic
happens *after* `stripLen` is applied, so we can't match on `subdir/*`.
This change adds a `relative` argument that makes this possible by
filtering files before doing any processing, and setting `stripLen` and
`extraPrefix` accordingly.
The current wrapper only includes vim, gvim and the man pages
(optionally). This rewrite distinguishes two scenarios, which I expect
cover the majority of use cases:
- standalone mode, when `name != "vim"`, means the user already has a
vim in scope and only wants to add a customized version with a
different name. In this case we only include wrappers for `/bin/*vim`.
- non-standalone mode, when `name == "vim"`, means the user expects a
normal vim package that uses the specified configuration. In this case
we include everything in the original derivation, with wrappers for
all the executables that accept a vimrc.
types.optionSet has been deprecated for almost 10 years now
(0e333688ce)! A removal
was already attempted in 2019
(27982b408e), but it was promptly
reinstantiated since some third-party uses were discovered
(f531ce75e4178c6867cc1d0f7fec96b2d5c3f1cb).
It's finally time to remove it for good :)
Conflict in pkgs/development/libraries/libvirt/default.nix
required manual adjustments. The fetched patch is already in src.
I checked that libvirt builds.
Few things going on in this commit:
Do not print "Building subPakage $pkg" message if actually going to skip the
package. This was confusing to me when I was trying to figure out how to set
excludedPackages and seeing the "Building subpackage $pkg" messages for
packages I wanted to skip. Turns out this messages was being printed before
checking if we actually wanted to build the package and not necessarily that my
excludedPackages was wrong.
Make go-packages look a little bit more like go-modules, by adding testdata to
the default list of excluded packages.
This commit also does some setup outside the buildGoDir function so that we
avoid checking `excludedPackages` for every package and cut down the number
of grep calls by half since we always want at least one grep for the default
excludedPackages, might as well just add to the patterns being checked.
Finally, adds documentation for usage of excludedPackages and subPackages. I
had to read the implementation to figure out how to correctly use these
function arguments since there was no documentation and different uses in the
code base. So this commit documents usage of the arguments.
