v_CTRL-A/X only increments the first number on each line.

I am not sure if this behavior is intended or overlooked. Either case, this is a feature request or bug report, respectively.
It would be nice if all digits in, e.g.

 *    0 ┃ 1 ┃ 2
 *   ━━━╋━━━╋━━━
 *    3 ┃ 4 ┃ 5
 *   ━━━╋━━━╋━━━
 *    6 ┃ 7 ┃ 8

could be incremented simultaneously with v_CTRL-A. Or even make a sequence from:

 *    0 ┃ 0 ┃ 0
 *   ━━━╋━━━╋━━━
 *    0 ┃ 0 ┃ 0
 *   ━━━╋━━━╋━━━
 *    0 ┃ 0 ┃ 0

with v_g_CTRL-A.
Many thanks.

That was not the intention of the visual increment. The initial idea was, to select only those numbers that need to be incremented will be selected and then incremented. Making visual increment increment several numbers within a selected range was not intended.

Thank you for your prompt reply :-D
Then this is a feature request.
Let me further clarify it. Suppose I have the following code:

std::string words[5];
words[0] = "The";
words[0] = "cat";
words[0] = "on";
words[0] = "the";
words[0] = "tree";

Then selecting from the third line onwards and, while on visual mode, pressing g-CTRL-A produces:

std::string words[5];
words[0] = "The";
words[1] = "cat";
words[2] = "on";
words[3] = "the";
words[4] = "tree";

So far so good.
However, if I have this other code:

vector<int> indexes = {
        0, 3, 4, 9, 12,
        20, 21, 22, 29, 36,
        37, 52, 41, 92, 120 };

and suddenly I realize that the indexing origin I need is 1 rather than 0, then it would be nice, and intuitive I think, to be able to increment by visual select all the numbers and CTRL-A.
Right now, only the first number on each line is incremented, which I find inconvenient and counter-intuitive (because my visual selection covers all the numbers).
Currently, I replace ',' by newlines, increment the numbers, and join them back with J to get the desired result.

Do folks have a preference for how this would be implemented? I don't think changing the behavior of v_CTRL-A et. al. is the right approach since it seems reasonable to have both the current behavior and the requested feature in some capacity.

I had two thoughts:

• Create four new key combinations (to pair with v_CTRL-A, v_CTRL-X, v_g_CTRL-a and v_g_CTRL-X), or
• Add a new option specifying how many numbers per row to inc/decrement (default to 1 to preserve current behavior)

Are there other approaches that make sense? I'd be happy to explore creating a patch.

I think it's already a bad thing that precious keys like Ctrl-A and Ctrl-X are wasted to number incrementing. How about a dedicated Ex-command?

Currently, to increment all numbers:

:%s/\d\+/\=1+submatch(0)/g
