Abbreviate list of names until they fit Given a list (array) of names, your challenge is to join the items using some glue and abbreviate the longest items first until the joined string fits a maximum length. And output that string. Since the glue is part of the final string, the length of the glue is included too 

Abbreviation is done using the … character

Examples

For example when | is the glue and 20 is the maximum length


giraffe would become giraffe (length = 7)
giraffe, Spiny lumpsucker would become giraffe|Spiny lumps… (length = 20)
giraffe, Spiny lumpsucker, rhinoceros would become giraf…|Spiny…|rhino… (length = 20)
giraffe, Spiny lumpsucker, rhinoceros, Hellbender would become any of these:


gira…|Spi…|rhi…|Hel…
gir…|Spin…|rhi…|Hel… 
gir…|Spi…|rhin…|Hel…
gir…|Spi…|rhi…|Hell… (all length = 20)



Rules

The list, glue and maximum length are input parameters of the program.

When abbreviation is needed, abbreviation must be done on any of the longest items first. When the longest items are equally long, it doesn't matter which you abbreviate.

The output length is smaller than the maximum length when no abbreviation was necessary. When abbreviation needs to occur, the length of the output is exactly equal to the maximum length.

The order of the (abbreviated) items must match the order of the items in the input

You can't assume that the abbreviation character … and the glue won't occur as characters in the items in the list.

Update

I'm afraid that I overlooked the fact that the length of the glue concatenated with many items by itself may result into a string that is longer than the allowed maximum length. Without considering this, your program may run into an infinite loop. I prefer your program to throw an error in this case. I hope that's not too much of an inconvenience for the ones who already wrote an answer or that are busy writing one. To throw an error is NOT a requirement to win, but I would appreciate if you add a variant that does.

The winner

This is code-golf, so the shortest valid answer – measured in bytes – wins.

Explanation

This is what I call the Jelly syndrome: the easy part is explaining the algorithm, the hard part is explaining how you found the exact order to put the code in to make it execute correctly.

                   L         whose length
                    &gt;        is larger than
