... whatever I said in the precedent post, at least VS9 let us extend it and create macros as well.
Unfortunately, I could not create a macro in C# so I had to use a language that I do not like at all, Visual Basic, and the result is an alpha macro that allows us to create "more clever"
regions and
outline for brackets as well.
More clever regions
There is another macro that goes around since Visual Studio 2005 but it has some bug and/or problem with nested regions plus it does not allow us to write directly in the region what the region is about
//#region whatever
...
//#endregion
--- to obtain
//#region whatever[...]
--- instead of
// another "boring" comment over the region
[...]
At the same time that macro put every region, nested or not, at the beginning of the line. It is not such a big problem, but I prefer this version.
Brackets outline
This is absolutely experimental and there are hundreds of problems, but for a couple of files it is doing its job.
What's next
Christmas, holidays, relax, if it is possible, and a better parser (a char by char via VB, I cannot even imagine me doing it!!!) so be patience please, and enjoy this alpha release :)
