Idea: A way to fold the *first* line, in similar to "foldLastLine": true.

[HolyBlackCat]

Let's say I have this rule:

{
    "begin": "{",
    "end": "}",
}

If I apply it to:

void foo()
{
    //
}

It folds to:

void foo()
{ …

I can show or hide } using "foldLastLine", but there's currently no way to show/hide the {. I.e. no way to fold that to:

void foo() …

I think it would be nice to have something like "foldFirstLine", which moves the start of the fold one line up.

I'd then create two rules: one that matches a line that has nothing but { and whitespace ("foldFirstLine": true), and the fallback one that matches { elsewhere (false).

It's available in the newest version but I've named it foldBeforeFirstLine. More details at https://github.com/zokugun/vscode-explicit-folding/blob/master/docs/rules/begin-end.md#foldbeforefirstline

@daiyam Oh, nice! But it breaks when two folding markers cancel each other out on the same line.

#include <iostream>


int main()
{
    std::cout << "Hello!\n";
}

I have folding rules for both () and {}, and this is the result:

Would be nice if the pairs of markers on the same line (() in this case) wouldn't activate this property.

Can you give me your rules?

"explicitFolding.rules": {
    "cpp": [
        {
            "begin": "{",
            "end": "}",
            "foldBeforeFirstLine": true,
        },
        {
            "begin": "(",
            "end": ")",
            "foldBeforeFirstLine": true,
        },
    ]
}

The new version (0.24.1) should be out with the fix.
