如何在Go中支持Allman样式编码？

In all the projects I've worked with in other languages the bracing-style of choice has been the Allman Style(aka ANSI style). The lack of a free-form bracing style(parenthesis too) is something I miss from other C-style syntax family of languages when working in Go.

Can anyone come up with a way to make the Go compiler accept the following bracing-style?

package main

import "fmt"

func main() 
{
    f()
    fmt.Println("Returned normally from f.")
}

func f() 
{
    fmt.Println("In function f.")
}

Note I am aware of the arguments for why Go was designed with such artificial 'limitation', but I'm not really buying into it. I'm a firm believer that the bracing-style used should really be decided by the coding-standard adopted by the people or company working on the code-base rather than being forced upon by the language itself.

As such please consider my question within the scope of 'how it can be done' rather than 'why not to do it and just adapt'.

Thanks

This may not be exactly what you are looking for, but it is one possible way.

You could write a 'translator program,' essentially an incredibly simple compiler that converts from what you wrote, effectively a Go variant, to what the Go compiler itself expects.

You could do that with something along the lines of a program, even shell script, that applies the regular expression 's/( )$^\s*{/{\1/g' to the entire program (though it would need to look at the full string of the file and not break it up line-by-line, so you couldn't just pass that expression as an argument to sed, for example). Then write the converted file out to a temporary one, and run the Go compiler on it.

This method has the advantage of not requiring any changes to Go itself, though the disadvantage is that your files will not compile without your extra script. If you normally use a Makefile, this is probably fine, but sometimes could still be inconvenient.

Succinctly, no. The language is (or was a year or more ago) defined with semi-colons, and the compiler inserts semi-colons implicitly at the ends of lines - unless there's a brace at the end of the line. So, if you write a condition (which doesn't need the parentheses, please note) and do not put an open brace at the end of the line, then the Go compiler inserts one for you - leaving a null statement after the if, and the braces enclosing a block that is executed unconditionally.

@epw suggests a reformatter; I think that is a reasonable suggestion. Go comes with gofmt to convert to the canonical Go style. You'd have to write something to convert from canonical to Allman style, and vice versa, and ensure that you pre-compile your Go-Allman source into Go-canonical format before compiling it to object files. On the whole, this is more traumatic than accepting that Go has its own rules which are no more eccentric than Python's rules and that it is simplest to go with the flow and accept that coding in Go involves coding in non-Allman (approximately K&R) style. (I like and use Allman style in C; I use Go-style in Go.)

I double the braces up.

if x < 0 {
{
    return sqrt(-x) + "i"
}}

It's not ideal but better than trying to scan columns 1-120 for matching braces.
