如何在Bazel Query中查找及通过合规工具获取当前工作区名称？

Awesome question! Ditching manual file parsing with cat+grep is always a good move—Bazel gives you clean, built-in ways to grab the workspace name directly. Here are the top methods, ranked by reliability and ease of use:

1. bazel query with Template Output (No External Tools Needed) #

This is the gold standard: it uses Bazel's own query system to pull the exact name defined in your WORKSPACE file, no extra dependencies required.

bazel query --output=template --template="{{.name}}" @//:workspace

How it works: #

• @//:workspace targets the workspace rule you defined in your WORKSPACE file (the one with workspace(name = "your_workspace")).
• The --template="{{.name}}" flag tells Bazel to output only the name field of that rule, skipping all other metadata.

2. Alternative bazel query Method (Simple Sed Parsing) #

If you prefer a slightly shorter command (and don't mind a tiny sed call), this works too:

bazel query --output=label_workspace @// | sed 's/^@//'

How it works: #

• --output=label_workspace returns the workspace prefix for the root target (@your_workspace).
• The sed command strips the leading @ to leave just the workspace name.

3. bazel info (Fallback, Directory Name Dependent) #

Only use this if your workspace's directory name exactly matches the name in your WORKSPACE file—Bazel doesn't enforce this, so it's less reliable:

basename "$(bazel info workspace)"

How it works: #

• bazel info workspace returns the full path to your workspace directory.
• basename extracts just the last part of that path (the directory name).

Final Recommendation #

Stick with the first method (bazel query with template output) for the most consistent and trustworthy result—it works no matter what your directory structure looks like, and it directly reads the official workspace name from your configuration.
