我的存储库中有一组文件。如何从bazel中的那些文件中生成一个zip文件。我找到了tar.gz等的规则,但是找不到找到zip归档文件的方法。
找到了提到拉链的参考文献,但无法弄清楚如何加载和使用它。可以使用淡褐色的人帮忙吗?
拉链实用程序位于@bazel_tools//tools/zip:zipper
,这是它的用法:
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genrule
像这样使用:
$ 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

可以类似地在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"},
)
