That's something I've started doing too. It's not just a matter of alignment either - I think the first argument on the same line as the function name is easy to miss. It all blends in together.

Of course, it would be even better still if Scintilla would be willing to add elastic tabstops (I'm getting increasingly annoyed that it doesn't, and that it doesn't even seem receptive to the idea, for technical reasons), because then I *could* do exactly what I used to with absolutely no problem:

Scintilla has 3 word wrapping modes, so long lines should not be a problem.

Strange... did not know that, but I have only used geany for a while already.

It may work with one developer who likes using tabs, but as soon as you get a mix of developers, you invariably get a mix of spaces and tabs unless _everyone_ involved is really careful, and that rarely happens. It's just too easy to use spaces without realizing that someone else used tabs or even that you yourself are using spaces, depending on your editor's settings.

Oh, it can be. But what generally happens in environments where spaces are required is that everyone sets up their editors to insert spaces when you hit the tab key instead of a tab (if everyone is using a common IDE, it's probably even required), so it becomes pretty much impossible to enter tabs by accident, whereas in an environment where tabs are used, you're not going to disable the spacebar, so spaces can still be inserted. So, generally, in a spaces-only environment, you don't run into problems with tabs.

Just FYI, in Eclipse, the auto-indentation that happen when you press Enter will use the indentation from the previous line (whether it's spaces, tabs, or even mixed).
However, other editing operations that generate lines of code (like code templates, auto-generated code, refactorings like extracting a method, etc.) are not so smart and will indent with according to the default indentation you specify in the settings, they won't look at how the file is already indented.

In Eclipse you can press Shift-Tab to reduce the indentation by one level, regardless of whether it's using spaces or tabs. This also works if you have multiple lines of code selected in the editor. (so if you have 4 spaces of indentation and you press Shift-Tab anywhere on the line it will delete those 4 spaces, assuming you configured a level of indentation to be 4 spaces (that's usually the default though))

Why would editors not allow you to enter that right? I don't see what the problem would be, unless you configured your editor to replaces N spaces into a tab for indentation.

Works fine in Eclipse, again because when it auto-indents on Enter, it uses the indentation of the previous line. :)

	That depends what you mean by "align". I agree that for the
following, elastic tab stops would be best:

int      a;
SomeType b;

	However, for this, I think that spaces are better:

doSomething (someLongParameterThatJustifiesBreakingTheLine,
             someOtherLongParameterJustInCase);

I guess we disagree on that. Like I said in another branch, I used to do that, but then I found that mixing tabs/spaces before the first non-whitespace on a line is just asking for trouble.

I'd rather do it like this (assuming elastic tabstops):

doSomething(->someLongParameterThatJustifiesBreakingTheLine, ->            someOtherLongParameterJustInCase);

Of course, that does demonstrate that I've never liked putting any whitespace between a function name (or if/while/etc.) and the opening paren. YMMV.

	Yes, that is the main reason why I use spaces for indenting...

	Well, standard (printed) typographic practices put spaces outside
the parenthesis and none inside. And as opposed to a lot of
typographic rules, that one is a constant across languages and variants.
