# Wire: Automated Initialization in Go

Wire is a code generation tool that automates connecting components using
[dependency injection][]. Dependencies between components are represented in
Wire as function parameters, encouraging explicit initialization instead of
global variables. Because Wire operates without runtime state or reflection,
code written to be used with Wire is useful even for hand-written
initialization.

For an overview, see the [introductory blog post][].

## Project status

As of version v0.3.0, Wire is *beta* and is considered feature complete. It
works well for the tasks it was designed to perform, and we prefer to keep it
as simple as possible.

We'll not be accepting new features at this time, but will gladly accept bug
reports and fixes.

What is filesystem access?

Filesystem access

Package has a dependency with a floating version range.  This can cause issues if the dependency publishes a new major version.

What are floating dependencies?

Floating dependency

Contains a dependency which resolves to a remote git URL. Dependencies fetched from git URLs are not immutable can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are git dependencies?

Git dependency

Contains a dependency which resolves to a GitHub URL. Dependencies fetched from GitHub specifiers are not immutable can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are GitHub dependencies?

GitHub dependency

What is an AI detected anomaly?

AI detected anomaly

AI has identified this package as malware. This is a strong signal that the package may be malicious.

What is AI detected malware?

AI detected potential malware

AI has determined that this package may contain potential security issues or vulnerabilities.

What are AI detected security risks?

What are high entropy strings?

High entropy strings

Contains unicode homoglyphs which can be used in supply chain confusion attacks.

What are unicode homoglyphs?

Unicode homoglyphs

Contains a dependency which resolves to a remote HTTP URL which could be used to inject untrusted code and reduce overall package reliability.

What are http dependencies?
