<p dir="ltr">Hi,<br>
I see an interest in keeping all source code in abstract code at least as a compilation option. <br>
This could allow to beautify code automatically with the rules of owner by rewriting back to disk the source code. <br>
Numbers of blanks per tabulation, max width of code, some want 80 colons, some other 100 for example. <br>
This could help to create a tool to let respect the coding standard of owner project. <br>
Regards <br></p>
