[英]How do I zip files in bazel
我的存儲庫中有一組文件。 如何從bazel中的那些文件中生成一個zip文件。 我找到了tar.gz等的規則,但是找不到找到zip存檔的方法。
找到提到拉鏈的參考資料,但無法弄清楚如何加載和使用它。 可以使用淡褐色的人幫忙嗎?
拉鏈實用程序位於@bazel_tools//tools/zip:zipper
,其用法是:
Usage: zipper [vxc[fC]] x.zip [-d exdir] [[zip_path1=]file1 ... [zip_pathn=]filen]
v verbose - list all file in x.zip
x extract - extract files in x.zip to current directory, or
an optional directory relative to the current directory
specified through -d option
c create - add files to x.zip
f flatten - flatten files to use with create or extract operation
C compress - compress files when using the create operation
x and c cannot be used in the same command-line.
For every file, a path in the zip can be specified. Examples:
zipper c x.zip a/b/__init__.py= # Add an empty file at a/b/__init__.py
zipper c x.zip a/b/main.py=foo/bar/bin.py # Add file foo/bar/bin.py at a/b/main.py
If the zip path is not specified, it is assumed to be the file path.
因此,它可以被用在genrule
這樣的:
$ tree
.
├── BUILD
├── dir
│ ├── a
│ ├── b
│ └── c
└── WORKSPACE
1 directory, 5 files
$ cat BUILD
genrule(
name = "gen_zip",
srcs = glob(["dir/*"]),
tools = ["@bazel_tools//tools/zip:zipper"],
outs = ["files.zip"],
cmd = "$(location @bazel_tools//tools/zip:zipper) c $@ $(SRCS)",
)
$ bazel build :files.zip

Length Date Time Name

可以類似地在Starlark中使用它:
def _some_rule_impl(ctx):
zipper_inputs = []
zipper_args = ctx.actions.args()
zipper_args.add("c", ctx.outputs.zip.path)
....
ctx.actions.run(
inputs = zipper_inputs,
outputs = [ctx.outputs.zip],
executable = ctx.executable._zipper,
arguments = zipper_args,
progress_message = "Creating zip...",
mnemonic = "zipper",
)
some_rule = rule(
implementation = _some_rule_impl,
attrs = {
"deps": attr.label_list(),
"$zipper": attr.label(default = Label("@bazel_tools//tools/zip:zipper"), cfg = "host", executable=True),
},
outputs = {"zip": "%{name}.zip"},
)
最近將一個基本的pkg_zip
規則添加到rules_pkg
。 這是單元測試中的一個基本用法示例:
load("@rules_pkg//:pkg.bzl", "pkg_zip")
pkg_zip(
name = "test_zip_basic",
srcs = [
"testdata/hello.txt",
"testdata/loremipsum.txt",
],
)
