Add diff chunk header lines to Git

Search Terms

userdiff xfuncname

Suggestion

Please add regular expressions to https://github.com/git/git/blob/master/userdiff.c such that TypeScript constructs can be identified in a predictable manner by the Git diff algorithm.

Use Cases

When I do a git diff or git add -p that includes TypeScript code, it's nice to see the function and/or class names of the changed lines I am looking at.

Examples

• git diff -- *.ts
• git add -p -- *.ts

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.
  • Particularly "Provide a structuring mechanism for larger pieces of code."

Empieza revisando userdiff.c de Git, que el issue identifica como el punto de entrada de la implementación, e inspecciona cómo los patrones de lenguaje existentes exponen los nombres de funciones o clases en los encabezados de diff. Añade patrones de TypeScript para archivos .ts y, después, verifica que git diff y git add -p muestren los nombres de las construcciones relevantes para los ejemplos del issue.
