Newlines in Segment Names

[jasondalycan]

My platform is Debian Bullseye (WSL2), Node.js 16.

When accessing req.msg.segments within the server component the segment names all appear to be prefixed with a newline:

See the following example:

console.log(req.msg.segments);

The message is sent via dcm4che hl7send and contains the following:

my guess would by the incoming messages are using a different segment seperator, probably \r\n ... the default the parser expects is \r https://github.com/hitgeek/simple-hl7/blob/master/lib/hl7/parser.js#L17 ..

You can pass a different segment seperator via the parser options. When using a server component, you can pass a parser to use. https://github.com/hitgeek/simple-hl7/blob/master/lib/server/tcp-server.js#L23

so it might look something like

var parser = new hl7.Parser({ segmentSeperator: '\r\n' })

var server = new hl7.tcp( { parser: parser });

Also you could try using v4, which is also availible on npm. v4 will inspect the message and use the correct segmentSeperator.
