Splitting output then adding it together

Is it possible with a macro to do something similar to: So-and-so attacks and rolls: [[@{selected|repeating_weapon_0_attack}]] + [[@{selected|repeating_weapon_0_attack-ability}]] + [[3df]] for a total of [[????]] to hit! What would go in the [[????]] to add or sum all of the other dice rolls on that line? Is this even possible or is this the realm of the API?

You really want it in a natural sentence? Otherwise, if you just write "/roll @{selected|repeating_weapon_0_attack}+@{selected|repeating_weapon_0_attack-ability}+3df", you'd get almost the same output.

You'd need the API for that. Macros have no way of storing a value for later use.

Generally you'll see multiple attacks split up intentionally. (depending on the game system; if the enemy dies from the first swing, you can use the next swing against something else) ie: instead of weapon0+weapon0=both weapons..... /me ATTACKS! [DualWield] Hit1:[[@{selected|repeating_weapon_0_attack}]] Dmg1:[[@{selected|repeating_weapon_0_dmg}]] Hit2:[[@{selected|repeating_weapon_0_attack}]] Dmg2:[[@{selected|repeating_weapon_0_dmg}]]
