I am having trouble understanding following sentence:

> 不満を吐き出すだけ吐き出せば、スッキリするだろう。

It is taken from a novel and in this particular scene the characters are
complaining about how horrible their trip has been up to this point. The main
character is, however, not interested in taking action to better their
situation...

According to that I think that this sentence is similar to constructions like
出来るだけ or even やるだけやった. Therefore, I understand above-stated sentences as
something along the lines of 'If they (just) get all of their complaints out,
they surely will feel better'

I am highly unsure whether my understanding is correct or a complete miss...

In any case, if somebody could explain meaning and especially the pattern
working behind the construction I would be more than a little thankful.

question
grammar translation meaning particle-だけ
だけ between two verbs / second verb performing an action on だけ construction
> 「不満{ふまん}を吐{は}き出{だ}す **だけ** 吐き出せば、スッキリするだろう。」

There are basically two patterns to this verb-だけ-verb construct.

> 1) 「Verb in **Attributive** Form + だけ + Same Verb in any form」

meaning "to [verb] to a degree". That degree is generally fairly limited.

> 2) 「Verb in **Potential** Form + だけ + Same Verb in any form」

meaning "to [verb] as much as possible"

"In any form" simply means that the form (of the second verb) changes
depending on what you want to say.

「吐き出す **だけ** 吐き出す」 uses pattern #1 above -- "performing the action of 吐き出す to
a degree".

This means that you were thinking of the meaning of pattern #2 instead. In
other words, you were thinking of the meaning of 「吐き **出せる** だけ吐き出す」.

Thus the sentence in question means something like:

> "If you vent your complaints a little, you will feel better."

When I was passing by a cheap pop-up clothing store a couple of days ago, a
clerk was shouting:

「見るだけ見てってくださ～～い！全品{ぜんぴん}お安{やす}くなっておりま～～す！」

That is pattern #1, too. "Please have a look insi~~de!"

Pattern #2 works like below.

「全部食べなくていいよ。 **食べられる** だけ食べて。」

"You don't have to eat all of it. Just eat as much as you can."

You're almost on the nose! This is a construction we use frequently, and while
related to できるだけ through the use of だけ, it carries a slightly different
meaning due to the use of the plain conjugation (連体形) as opposed to the
potential form (可能形).

Take these two examples:

> 1) 飲めるだけ飲んでみます。

and

> 2) 飲むだけ飲んでみます。

In 1), the speaker is using だけ exactly how you referenced in the second half
of your question.

> 飲める(だけ) → (All/To the extent/As much as) one can drink
>
> 飲んでみます → One will try drinking

So in English, we would translate this to something like:

> I'll try drinking as much as I can.

However in 2), the speaker isn't talking about their _potential_ to drink
anything; they didn't use the potential form.

If we wanted to analyze this sentence like we did 1), we could say:

> 飲む(だけ) → (All/To the extent/As much as) one (will) drink
>
> 飲んでみます → One will try drinking

So literally:

> I'll try drinking as much as I'll drink

It doesn't really sound like the speaker wants to drink anything, does it?

If we wanted a more natural-sounding translation, we could say something like:

> I'll give drinking it a shot (but don't expect me to drink all of it)

This to me is the key to understanding 連体形+だけ vs 可能形+だけ.

With the potential form, we're saying we'll do all we can, but with the plain
form, we're only saying we'll do what we will do.

Applying this to your example, you give:

> 不満を吐き出すだけ吐き出せば、スッキリするだろう。

If we instead said:

> 不満を吐き出せるだけ吐き出せば、スッキリするだろう。

This would carry the meaning:

> If they get **all** of their complaints out, they surely will feel better

However in the plain form, as is, I would translate it closer to:

> If they (would) **just** get their complaints out **a little** , they'd
> probably feel better

The "just" and "a little" here are my attempts to show that "they" are
probably a bit reluctant to complain.
