* make the tarball 555
* Split the bins out from the rest of the package and combine the
packages.
This solution is horrible. The better solution is
- We need something like pkgfilegroup in rules_pkg, so we can specify
exectuable mode next to the file.
- But we do not want rules_pkg to appear in the rules/BUILD file
because that would make a runtime dependency.
So we need to
- rewrite rules/BUILD when going into the package.
- or provide magic mapping of files names to mode bits
- or something entirely different.

This rule is an alternative for genrule(): it can
run a binary with the desired arguments,
environment, inputs, and outputs, as a single
build action, without shelling out to Bash.
Fixes https://github.com/bazelbuild/bazel-skylib/issues/149
native_binary() wraps a pre-built binary or script
in a *_binary rule interface. Rules like genrule
can tool-depend on it, and it can be executed with
"bazel run". This rule can also augment the binary
with runfiles.
native_test() is similar, but creates a testable
rule instead of a binary rule.
Fixes https://github.com/bazelbuild/bazel-skylib/issues/148
RELNOTES[NEW]: The new `native_binary()` and `native_test()` rules let you wrap a pre-built binary in a binary and test rule respectively.
This new test rule compares two files and passes
if the files match.
On Linux/macOS/non-Windows, the test compares
files using 'diff'.
On Windows, the test compares files using
'fc.exe'. This utility is available on all Windows
versions I tried (Windows 2008 Server, Windows
2016 Datacenter Core).

Move maprule() to a private directory, to
discourage use of it. I (@laszlocsomor) am
planning breaking changes to it.
Also move private files (rule implementations) to
a subdirectory "rules/private/", to clean up the
"rules/" directory.
This PR adds two new rules: write_file and
write_xfile.
Both rules solve a common problem: to write a text
file with user-defined contents.
The problem is routinely solved using a genrule.
That however requires Bash, since genrules execute
Bash commands. Requiring Bash is a problem on
Windows.
The new rules do not require any shell.
The only difference between the rules is that
write_xfile creates an executable file while
write_file doesn't.

This PR adds two new rules: copy_file and
copy_xfile.
Both rules solve a common problem: to copy one
file to another location. The problem is routinely
solved using a genrule. That however requires
Bash, since genrules execute Bash commands.
Requiring Bash is a problem on Windows.
The new rules do not require Bash on Windows (only
on other platforms).
The only difference between the rules is that
copy_xfile creates an executable file while
copy_file doesn't.

In this PR:
- In the _resolve_locations function: use the
Bash-less ctx.resolve_tools function to resolve
the runfiles manifests and inputs of tools,
instead of using ctx.resolve_command for
the same purpose.
- In the _custom_envmap function: no longer
resolve $(location) references when
creating the envvars from custom_env, because
those references were already resolved in
_resolve_locations.
The ctx.resolve_tools() method was added in this
PR: https://github.com/bazelbuild/bazel/pull/7139

* Add rules to the test_deps target.
Likely needed for anyone doing integration tests using skylib.
* Default public visibility and only tag things that are private.
maprule() is an improved version of
native.genrule(), with the following advantages:
- Maprule can process source files in parallel,
creating separate actions for each of them.
- Maprule does not require declaring all output
files. Instead you declare templates for the
output files yielded for each source. Therefore
N source files and M templates yield N*M
outputs.
- Maprule supports both Bash and cmd.exe syntax
for its commands via the specialized rules
bash_maprule and cmd_maprule.
- Maprule's cmd attribute does deliberately not
support $(location) expression nor Make
Variables, in order to avoid issues and
challenges with quoting. (In case of cmd.exe
passing empty arguments is impossible). These
paths can be passed as envvars instead.
- Maprule's add_env attribute does support
$(location) expressions (and some extra
placeholders) and is the idiomatic way to pass
execpaths of labels in "tools" or "srcs" (the
shared sources available for all actions) to the
command.
