# go-messagefix

```shell

go get github.com/delthas/go-messagefix

```

go-messagefix offers an io.Reader that transforms RFC822 messages (.EML file contents) on-the-fly from another io.Reader.

The message is slightly transformed/fixed if it breaks the RFC822 spec so that strict implementations may accept it.

These transformations are best-effort heuristics and can include:

- closing any multiparts that are still open at EOF

- correctly indenting continuation headers that were not indented

## Example

```go

message := `Foo: Bar

Broken-Header:

"This_header_is_broken"

Content-Type: text/plain

Data

`

r := strings.NewReader(message)

fix := messagefix.NewReader(r)

io.Copy(os.Stdout, fix)

```

This prints:

```

Foo: Bar

Broken-Header:

 "This_header_is_broken"

Content-Type: text/plain

Data

```

The header continuation is properly indented.
