A most welcome feature would be for VAX to emulate the block indentation found in Visual Studio 6 and many other editors. I.e. if you select lines and press Tab, it shifts all text by the same amount to the right. For instance, indenting the body of this function:

void f() {
    /*
     * Blah blah
     */
    g(awfulllylongexpression,
      blob);
}
yields:

void f() {
        /*
         * Blah blah
         */
        g(awfulllylongexpression,
          blob);
}


Visual Studio 2003 ruins it by aligning each line individually to a tab stop, yielding:

void f() {
        /*
        * Blah blah
        */
        g(awfulllylongexpression,
        blob);
}


I've come up with a workaround of settings the indent size to 1 and these macro's tied to the Tab and Shift-Tab key. It allows the tab key to be used for completion in VAX, but it's not quite up to par with some 15 year old editors.

        Else

            selection.Indent(4)

the problem here is that this could be the thin end of the wedge. VA has a "format on paste" option, but all this option does is to call the IDE's format function on the newly pasted code.

here you are asking VA to "argue" with the IDE's formatting code instead of just calling it. people have asked before now for VA to format the code how they want it. i myself have asked for this

the basic problem here is the vast number of options on "proper" formatting. a full blown code formatting program has a staggering number of options, to allow people to fine tune it how they want. given this complexity Support have always said VA will not do this.

I'm very happy VAX allows easily turning off format-after-paste, because there's indeed no way for VS or VAX to get formatting right.
The problem I mention is about keeping the existing formatting.

In the mean time, I digged quite a bit deeper into the macro/Visual Basic/whatever they call it. This works pretty good and doesn't require you to set Indent size to 1 - it does itself, temporarily. The problem with it is that it needs to ensure the file is of type C/C++ and I can't find a proper way to do that.

i have often considered digging into the IDE's macro programming language, but i have yet to find the time. can you grab the current file name, and simply base your actions on the file extension?

i know that VA's alt-o feature has been described as something you could implement with a simple macro, comment from here:

http://www.codeproject.com/macro/kingstools.asp

you may find some useful clues / hints in the source code.

My read of his macro has him checking the extension in the needFix function. He apparently doesn't consider that a "proper way" to do that. Perhaps he is concerned about the reusability of the macro in the general case (people could add some extensions to the list that is identified as C/C++ files and headers - can't they?). Not to mention the already existing extensions .cxx, .c++, and .hxx, just to name a few.

*oops* that is what comes of not reading the macro before posting

with regard to a "proper" way of detecting the file type, VA its self relies on the file extension to work out the file type. this is why there are registry keys holding known extensions.

i have relied on the content of a data file to help me guess its format before now, but that is not really going to work with C++ code, since there is no obvious and really simple test. or at least none that i am thinking of.

The "proper" file type is the one applied by the Visual Studio editor. The maco has to query and change the IndentSize property for the precise file type ("C/C++").

Note that at one point while developing the maco random characters were popping up in the file whenever undoing stuff, without there being an unbalance in the UndoContext statements. Clearly this macro language is pretty unstable so don't start rewriting VAX in it...
