bazel-bin/buildifier.bash commands

[anandwana001]

I am currently on macOS, and not able to run the Buildifier.bash file.

1. Am I using commands incorrectly?

Without rules, I tried brew install buildifier and it works smoothly.

buildifier --lint=warn --mode=check --warnings=-native-android,+out-of-order-load,+unsorted-dict-items -r app data 
domain model testing utility third_party tools BUILD.bazel WORKSPACE oppia_android_test.bzl

Tried 1 more option:

1. Downloaded the binary file from here - https://github.com/bazelbuild/buildtools/releases/download/$BUILDIFIER/buildifier where BUILDIFIER="3.4.0"
2. Make it executable chmod a+x buildifier
3. Error - cannot execute binary file

If you want to build a binary and then run it independently, use bazel build instead of bazel run, the latter creates a special bash script that's meant to be used by bazel run.

In your case, if you want to just build buildifier, you don't need to create a new repository, just check out this one, run bazel build //buildifier there and use the generated binary (you'll see its path in the console). It's a self-contained binary, you can copy it anywhere.

Alternatively, just download it from GitHub as you've described above, but you need to fetch a binary for MacOS, before 4.0.0 it's called buildifier.mac, starting with 4.0.0 on it's called buildifier-darwin-amd64. buildifier is just a copy of buildifier-linux-amd64, it's being uploaded there for compatibility reasons and will not be included in the future versions.

I'm having good luck with the following in my root BUILD.bazel:

load("@com_github_bazelbuild_buildtools//buildifier:def.bzl", "buildifier")

buildifier(
    name = "buildifier-fix",
    lint_mode = "fix",
    mode = "fix",
)

Then ran via:

$ bazelisk run //:buildifier-fix

This properly updates the script (bazel-bin/buildifier-fix.bash) that Vladimir mentions to have the arguments passed from the build file:

$ cat bazel-bin/buildifier-fix.bash
#! /usr/bin/env bash

BUILDIFIER_SHORT_PATH='../com_github_bazelbuild_buildtools/buildifier/buildifier_/buildifier'
ARGS=('-mode=fix' '-v=false' '-lint=fix')

...

I have the same issue as Akshay. I ran bazel build //:buildifier and bazel run //:buildifier. The same problem. Can someone help?

Edit: I gave up on building it myself. It seems the executable already available, buildifier-linux-amd64 works.
