As for functions, there is an explicit benefit in cutting your longer (pure!) functions into a few shorter ones if possible:

Functions communicate with the outside world only via arguments and returned values. The explicit split reassures the reader that this is indeed the case, and thus every reader doesn't have to establish this fact via careful reasoning again and again.

A long function might indeed be simple, but you never know until you check carefully.

(This only applies to pure functions. Natural language sentences and side effecting procedures are messier.)

On the other hand, function calls in hot code are expensive.

michaelfeathers• 11 years ago

Pareto Principle: don't treat all of your code as if it is "hot." It isn't.

eru4• 11 years ago

Only if your compiler ain't smart enough.

Yes, for some compilers and interpreters performance considerations will force you to write less than readable code.

JadeNB3• 11 years ago

On the third hand, premature optimisation is the root of all evil. :-) It's a lot easier to convert well chunked, modular functions into monolithic blocks than it is to go the other way around.

mbq• 11 years ago

I bet the author calls for making functions just right in size to leverage self-containment and complexity, instead of panicking after crossing some magical number of lines.

This is actually compatible with DRY, because overpartitioned functionality will require more state to be pulled from function to function, resulting in repeating, long argument lists.

marrs• 11 years ago

More basic than that, it also forces you to physically move away from the function in order to continue reading. It would be like turning to a different page in order to read the middle part of a paragraph.

blt2• 11 years ago

another way to accomplish this goal is to write your function using only const variables. every time you'd mutate a variable, use a new const variable instead. you end up transforming the code into static-single-assignment form, which is what compilers do anyway, so you can be sure it won't degrade performance.

this style really makes you wish C/C++ had if expressions. you end up using a lot of ternary operators to compensate.

it makes the code a bit more verbose, but its worlds better than poring through a function to make sure nothing is mutated in an unexpected way.

eru4• 11 years ago

I reach for Haskell whenever possible to get similar effects.

mattnewport• 11 years ago

I actually prefer ternary expressions in many situations, once you're familiar with the syntax they're more concise and more clearly an expression rather than flow control.

JadeNB3• 11 years ago

you end up transforming the code into static-single-assignment form, which is what compilers do anyway, so you can be sure it won't degrade performance.

I don't know my way around compiler internals, but this sounds a little suspect to me. It seems to me—just a tyro's opinion—that (1) work spent doing what the compiler will do anyway is probably work wasted, and (2) it is possible to get in the compiler's way even if you are trying just to do what it would do anyway, thus causing unexpected degradation.

btilly• 11 years ago

Have you measured this benefit in any empirical way?

It is a bit dated now, but Code Complete cites actual attempts to study the connections between function length and maintenance cost in real world code bases. The conclusion was that functions with a high internal complexity were maintenance hazards. Basically add up all of the if's, loops, and so on, and if that is a big number, then break it up. However long functions without internal complexity were not a maintenance hazard. This was true up to about 200 lines.

OK, a lot has changed since IBM studied maintenance costs in the 1980s. But the received wisdom today about short functions was already the received wisdom then. And the wisdom today is just as much based on opinion as it was then.

Is there any more reason why we should accept the received wisdom today than there was then?

eru4• 11 years ago

Good points.

My argument was actually mostly from a Haskell point of view, and a study there would be somewhat harder to define: you are defining functions all the time: especially in imperative code (do-block / monads) each line is actually a callback.

You could go by purely syntactical criteria, though. Culturally, even a single screenful of code is considered rather long for one definition in Haskell.

vacri• 11 years ago

A comma splice is a comma splice, and subbing in a colon doesn't change that. A semi-colon, the bastard offspring of the two, does... curious.

andybak• 11 years ago

His paragraphs are way too long for my tastes.

smanuel• 11 years ago

Disclaimer: I'm not a native English speaker.

Sorry but IMO the author has failed to prove his case. The text is not easy to read, and it's hard to follow the author's thought.

So long sentences and long paragraphs definitely don't help. It's either that or I should get tested for ADHD.

ticviking• 11 years ago

I think that's the what the author missed.

Short sentences are not about simplicity, they are about accessibility. While it was not hard for me to read his text. It did not flow, and was not easy to follow. Long sentences distract the reader with their additional complexity. Instead of being able to focus on the content, the reader must decipher the meaning. Then they can engage the idea.

Making it harder to understand content is a terrible way to communicate.

RyanMcGreal2• 11 years ago

The author seems to be deliberately trying to manufacture long sentences to make his point, mainly by taking two related sentences and pushing them together with a semicolon. It serves no purpose in improving comprehension and comes at the cost of making parsing more difficult. It feels rather like the sort of hypercorrection [1] that people sometimes make when they're trying to sound erudite.

1. https://en.wikipedia.org/wiki/Hypercorrection

idlewords• 11 years ago

Another thing people do when they're trying to sound erudite is ostentatiously [1] link definitions to concepts they think their readers can't look up for themselves.

1. Don't do that

copsarebastards2• 11 years ago

Just because I can look it up for myself doesn't mean I don't appreciate having a link, especially if the writer went to the effort of choosing a link that's better than the first Google search result.

1. Since apparently we’re overthinking things, have you considered that your oversensitivity to minor perceived offenses is because you’ve never been punched?

adwf• 11 years ago

My thought exactly: "Someone's found the semicolon key"

Most of those semicolons could be replaced with a full stop or comma without losing any meaning.

cfmcdonald• 11 years ago

John Donne, bad writer?

"If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bell tolls; it tolls for thee."

westoncb• 11 years ago

Actually, it does serve a purpose: it allows you to accurately mark a syntactic hierarchy, indicating clause separation, as distinct from phrase separation. This is especially important when you have two complementary clauses whose relationship should be highlighted, as in the author's

"So if you find yourself breaking sentences apart to follow a rule that sentences should be short, you’re doing it wrong; if they can be broken apart without much trouble, they also weren’t any trouble for the reader to understand in the first place."

Sure, he could make them two separate sentences—but why waste the opportunity to signal their relatedness? Separating the two with a period represents them as equally related to other surrounding sentences. We can decode their connection still, but signaling it explicitly just makes it smoother.

I found his writing to be extremely clear, easy to follow, and enjoyable to read.

RyanMcGreal2• 11 years ago

Here's the thing: two sentences right next to each other within the same paragraph are related. The sentence is merely one tier in the hierarchy of organizational structures that frame writing. The paragraph also forms a unit of structure in which one or more related sentences collectively convey an idea.

I'm not suggesting there is no use for a semicolon - for example, I like to use it as a separator for a list of clauses if one or more of the clauses contain commas - and of course this is one of those grey areas of English grammar in which the author's use is not objectively wrong. However, it overloads the sentence and makes reading more difficult without any real benefit over the simpler alternative of connecting related sentences in paragraphs.

Likewise, I'm not opposed to writing long sentences. After all, the first sentence in the previous paragraph runs 56 words. However, I am opposed to writing long sentences merely for the sake of claiming that long sentences are okay.

blunte• 11 years ago

It's been quite some time since I was in school, but it seems the author breaks grammatical rules regarding the number of phrases and clauses that can be strung together with punctuation. In addition, he uses a semicolon where a dash was necessary.

It's dangerous to publicly give a lesson as we sometimes stumble during our lecture (as I probably have done in my comments on the author's essay :) ).

harperlee• 11 years ago

As others have already pointed out, the author does not seem to command long sentences enough. But it can be a good choice for streams-of-consciousness; Marcel Proust is a good example of it. Here are his five longest sentences:

https://nathanbrixius.wordpress.com/2013/10/30/the-five-long...

In general, I'd recommend to read some Proust as his style is completely against the current trend of short, direct sentences à la Hemingway, and that can be refreshing!

By the way, I started reading Proust because of Nabokov's Lectures on Literature:

http://www.amazon.com/Lectures-Literature-Vladimir-Nabokov/d...

Which I recommend wholeheartedly.

mattlutze2• 11 years ago

As art this ^ sort of thing can be excused.

I would certainly hope that in most business or communication contexts, people aren't going to think a Proustian stream-of-consciousness rat nest is an acceptable piece of writing.

michaelhoffman• 11 years ago

Much of my job is scientific writing. I don't see long sentences as something that is automatically bad. I do see them as a kind of "writing smell" (much like a "code smell") that can indicate something hard to understand. And often the long sentences could be bisected with an increase of understanding.

When possible I write with a text editor and LaTeX, with one sentence per line. This makes it really easy to identify sentences that might possibly be too long.

dmlorenzetti• 11 years ago

One sentence per line is also an excellent strategy for when it comes time to "diff" two files. It helps diff identify edits (by giving it more anchoring lines to figure out what's actually changed), and it makes the output much easier to read.

tbrgmnn• 11 years ago

Rainymood• 11 years ago

“This sentence has five words. Here are five more words. Five-word sentences are fine. But several together become monotonous. Listen to what is happening. The writing is getting boring. The sound of it drones. It’s like a stuck record. The ear demands some variety. Now listen. I vary the sentence length, and I create music. Music. The writing sings. It has a pleasant rhythm, a lilt, a harmony. I use short sentences. And I use sentences of medium length. And sometimes, when I am certain the reader is rested, I will engage him with a sentence of considerable length, a sentence that burns with energy and builds with all the impetus of a crescendo, the roll of the drums, the crash of the cymbals–sounds that say listen to this, it is important.” - Gary Provost

webnrrd2k• 11 years ago

Like a lot of things, I think it depends mostly on the effort the writer puts into mastering his craft. I prefer the variety in length, and agree with it as a general rule. However, one counterpoint: Hemmingway seems to have done fine with (mostly) short sentences.

blt2• 11 years ago

The last sentence is still too long though ;)

Practicality• 11 years ago

You're just compromising. Removing complication does make it easier to understand. Short and simple is even easier.

However, it's hard to write that way, so most don't bother. If we rewrote your essay with a mixture of short and long sentences it would be stronger.

Shorter sentences can also seem less thoughtful—even childlike. That doesn't mean they are.

majkinetor• 11 years ago

Is there any science available about pure physical aspect of long sentence? I mean... more words to read might equal to more resources spent ... like ATP or neurotransmiters

awjr• 11 years ago

I write a lot of stuff, trying to churn out one post per week or so, sometimes more, sometimes less (at http://cyclebath.org.uk/).

If you are writing for a broad audience I try not to get too complicated. These days, I usually take the final post, and just throw it up onto http://www.hemingwayapp.com/ to get a feel for how well it reads.

As an experiment I tried to get a "Very Good". Each sentence was clean, had one idea in it, but the flow of the post was stilted. It removed all passion.

However I can be too clever for my own good. Communicating ideas in the simplest terms is exceptionally important. I get too involved in story telling. The Hemmingway App enables a good compromise.

alricb2• 11 years ago

ObPierreBourdieu:

This structure which is present in every artistic genre, and has been for a long time, today tends to work as a mental structure, organizing the production and perception of products: the opposition between art and money (the "commercial") is the generating principle of most of the judgments which, in matters of theatre, cinema, painting, literature, claim to establish the frontier between what is art and what is not, between "bourgeois" art and "intellectual" art, between "traditional" art and "avant-garde" art.

(from Pierre Bourdieu, Les règles de l'art, free translation)

abecedarius• 11 years ago

I found that hard to follow -- was that your intent? (What does 'this structure' refer to? What does it have to do with 'the opposition'? Are they the same?)

alricb2• 11 years ago

I didn't write it, Pierre Bourdieu did (in French, but my translation follows the sentence fairly closely), and he has stated that he writes like that so that he's hard to quote. In fact, to really understand the sentence, you'd need to read the one before it, and probably the one before that, and they're all about as complicated and hard to understand; you find yourself having to turn to the previous page just to remember what the subject of the sentence was.

arca_vorago• 11 years ago

For me, it's not whether the sentence is too complicated or too long, but the tools you use within it to make it stick (not the best word but I can't think of a better one at the moment) in the readers or listeners mind.

One of my favorite classes in uni was rhetoric, and one of my favorite books to this day is Farnsworth's Classical English Rhetoric. I highly suggest it as a tote around, open to a random page and read as much as you like and never be disappointed reading.

mattlutze2• 11 years ago

I've always learned the edict to simplify writing from as: when writing, try and keep it to simple, single compound, or single complex sentences. Rather than "don't do ___", it's "freely express yourself with ____".

Outside anything else, it's a more pleasant way to approach the topic, and there's a ton of freedom in it. Yes, it's similar to prescribing a word count or a page count because it puts a more-easily measured test on the writing. But it's also an indicating function to help stop a writer from introducing confusion through their grammar.

Some industries have done quite a bit of research into the subject. Take, for example, the aerospace industry's Simplified Technical English[1][2]. Here, research into the readability of flight and maintenance manuals identified that shorter sentences were easier to understand for English-as-a-Second-Language speakers. A grammar was developed to reduce some of English's flexibility and make construction more predictable. This, paired with shorter sentences, dramatically increased the usability of print media for aerospace and defense applications.

Shorter or simpler sentence construction can ultimately free the writer to be more expressive and to more clearly express his or her ideas.

And the pieces do have to be simpler, for the effort to make sense; otherwise the reader of the code is left contemplating not just a horrible mess, but a horrible mess that has metastasized.

This is called "Bulldozer Code"

Gibbon12• 11 years ago

Congratulations for reading the article and exacting content.

I think the meta observation is there are rules imposed on students to prevent them from developing bad habits. But these aren't hard rules in practice. Same applies to code slopping.

platz2• 11 years ago

I find your tone unnecessarily arrogant and passive-aggressive.

The point was (which the author made) that simply shortening sentences doesn't necessarily fix a problem with complexity, just like breaking up code without solving the complexity issues also doesn't necessarily fix the problem.

Congratulations for being a supercilious jerk.

putzdown• 11 years ago

The argument would be more compelling from a more compelling writer. The second sentence, "It’s one of the pieces of advice that I have always completely disregarded, as being obviously wrong..." contains a comma that hasn't appealed to the English eye since Jane Austen and is in any case unnecessary. Physician, heal thyself.

insickness• 11 years ago

The next sentence should lose the comma as well.

"A sentence that is long can still be quite simple, if it doesn’t require the reader to remember previous parts of the sentence in order to parse the rest."

It's almost as if he's using unnecessary commas to make up for the long sentence.

JustSomeNobody2• 11 years ago

The pause from the comma makes the sentence come off a bit condescending. I felt like I was being talked down to.

hellbanner2• 11 years ago

Speed reading technique: read 1/3 over on line 1, then 2/3 over on line 1, then 1/3 over on line 2, 2/3 on line 2.. etc. Drastically increases speed, even over the Gary Provost quote.

JustSomeNobody2• 11 years ago

It slowed me down. I was too busy thinking "1/3 2/3 1/3...".

grellas• 11 years ago

It is a good rule of thumb in writing not to make the reader work hard to get your meaning, to have to blast for it if you will.

Brevity promotes simplicity and simple things are much easier to understand than are those that are prolix.

So writing in a style consisting primarily of short, easy-to-understand sentences is in itself a good rule of thumb when aiming to write well.

But it is only a rule of thumb, as I see it, and when it is enshrined as something more, it can do more harm than good.

The English language is a marvel of complexity and has so many rich, diverse, and colorful elements that you cheat only yourself as a writer if you fail to give full scope to such elements in choosing how to express yourself in the written word. You want to make a driving argument? By all means, use active verbs to punch along short, compact thoughts with an aggressive rhythm. Want to weave fascinating characterization? Well, then maybe relax the feel a bit and, with Dickens, unwind a string of long, flowing sentences that carry your reader along into a wonderfully imaginative series of pictures, running page after page, that hardly turn on being short, compact, and punchy - indeed, that are the very opposite. The point is not that you want to go to one extreme or the other. The point is that, as one who seeks to write well, you should avail yourself of the rich set of tools available to you without feeling bound to adhere to any form of absolute rules about how best to use them.

So, write away! Go for feel. Go for rhythm. Go for clarity. Go for what best suits your purpose.

And, oh, yes, do keep it short and simple, except when you find it doesn't suit your purpose. A rule of thumb is just that. In the end, do what gets your point across for the long-suffering reader who deserves to have it done well.

rayiner2• 11 years ago

Because ambiguities in English sentences often cannot be resolved until the end,[1] readers tend to parse whole sentences before trying to fully understand them. Short sentences are a way of forcing readers to fully digest each thought before moving on to the next one.

Short sentences have additional benefits for persuasive writing (particularly legal writing). It's hard to hide anything in a short, simple sentence. Using them is a way of signaling your confidence in what you're saying.

[1] https://en.wikipedia.org/wiki/Garden_path_sentence

copsarebastards2• 11 years ago

You’re right; to humans, short sentences do signal persuasive arguments and confidence in your ideas. And not without reason. People often speak longwindedly when they are trying to hide something.

But there is another reason someone might use long sentences. They might be trying to express a complicated idea. Sometimes an idea cannot expressed in a short sentence. Usually you can break up a complex idea into a few short sentences, but that might make the reading choppy and hard to follow. A long sentence leads its reader through the connections between ideas. In contrast, separate sentences express the ideas and leave it up to the reader to figure out what the connections are between the ideas.

This leaves us with an apparent cognitive bias: if we are distrustful of long sentences, we become distrustful of complex ideas.

Given this, I wonder if modern anti-intellectualism stems from this sensible defensive mechanism.

harryh• 11 years ago

I don't think that's a cognitive bias. We should be inherently more suspicious of complex ideas. Complex ideas are more likely to be wrong than simple ideas due to the fact that their correctness rests on a greater number of assumptions.

davelnewton• 11 years ago

Writers are often advised to avoid long sentences. This is obviously wrong: the thing to avoid are complicated sentences. Long sentences can be simple if they don't require the reader to remember previous parts in order to parse the rest. Instead, each part extends the thought made in the previous one, with appropriate punctuation showing the relationship between the two; this sort of sentence can go on for lines without confusing anyone. A confusing sentence requires the reader to remember which verb was used forty words back, before it went off on a tangent. The cure for such sentences isn't simply bisecting them. Rearranging can bring separateed pieces of an idea together; if that doesn't work, one must drop the idea then explicitly take it up again later. Or, more brutally, axe the tangential remark. Not everything needs to be said, but if it does, say it somewhere else.

Seventy words shorter. I would have done the rest but I expired.

For those that missed the last plane to Miami (meaning all of you), the author was bitching that the rule in programming 'functions should be short, one page, etc' is as wrong as the rule that in writing sentences should be short.
