WriteFile writes content to a file in the repository.

Close syncs, closes the temp file, and atomically renames it to the target.

Dir returns the directory path of the repository.

Test helpers =============================================================

Canonical returns the canonical form of path: absolute, with all symlinks resolved, dot/dotdot segments eliminated, redundant separators removed, and

ReadFile reads a file from the repository.

ErrorMessage prints an error message with the icon.

CommitAll stages all files and creates a commit with the given message. Returns the SHA of the created commit.

setupProjectDir creates a nested directory hierarchy tmpDir/g/p/project and optionally places a clang-tidy config file at a given ancestor level. ance

PrimaryBold prints a message in the primary bold style.

Relativity classifies a path into one of the four categories.

WeaklyCanonical is like Canonical but does not require the full path to exist. It canonicalizes the longest existing prefix, then appends the remainin

Write implements io.Writer.

gitRun runs the git command in the given directory and returns an error if any.

CreateMockExe builds a callback-client binary at destPath with the callback server address baked in via -ldflags, and registers a handler to be called

findEntry looks up a directory entry by name, returning the actual on-disk name. On Linux, it opens the entry with O_PATH|O_NOFOLLOW (which requires o

IsInteractive returns true if the current execution environment is interactive (useful for colors/animations toggle).

NewGitRepo initializes a new git repository and returns a GitRepo for it.

QuoteIfSpace wraps in '"' if the string contains a space.

RevParse converts any commit reference (hash, branch name, tag name, etc.) to a full SHA1 commit hash.

Need skips the test if any of the given flags are disabled.

Resolve every `dhi.io/<repo>` FROM to its tag; untagged/unexpandable-$VAR → "" (fail-closed).

ExtractTarGz extracts a .tar.gz file to destDir. If stripTopDir is true, the first path component is removed from each entry (e.g., "jbrsdk-25.0.2-lin

AppendUnique appends elements to a slice only if they are not already present.

ExecRedirectOutput executes subprocess with forwarding of signals, returns stdout, stderr and exit code.

compilerCacheKey produces an unambiguous cache key for the (compiler, headerType) pair. A null byte is used as the delimiter because it cannot appear

Exec executes subprocess with forwarding of signals, and returns its exit code.

MakeAbsolute converts any path to an absolute path without calling filepath.Clean (which would collapse symlink/.. lexically). For DriveRelative paths
