{{stub#set:is contribution page=true}}<!-- prologue. Feel free to help fill this page out; you guys tend to refine this more than I do. This is (currently) mostly a brain dump of my general lines of preference embedded in a structured outline.-->So you want to see a problem tackled, and you know enough about it that you can write a solution or two yourself. If you're beyond simply [[Rosetta Code:Village Pump/Suggest a programming task|suggesting a task]], you can add one yourself.
 
A task has a very simple layout:

Examples</pre>
==Prerequisites==
===Create the page===
Come up with a title for your task (look at [[:Category:Programming Tasks|the current tasks]] to see what kind of name you should choose), type it in the search bar, and click "Go". There will be a "Create page" link on the resulting page somewhere. Click that, and you can begin editing.
 
A few guidelines for a good task title:
 
* Don't be too general; make the title closely focused on describing what the task is actually asking to do.
::If your task is "Generate the lyrics to 99 bottles of beer" for instance, a good title is "99 bottles of beer". A poor title would be "Generate song lyrics".
 
* Don't be too specific; don't include terms that are peripheral to the task, even if it is a common term.
::If your task is "Generate twin primes up to some limit"; a good title is "Twin primes", a poor title would be "Twin prime conjecture".
 
* Follow some simple capitalization rules:
:# The first character of the title should always be uppercase, even if referring to something normally lowercase.
:# The first character after a level separator ( forward solidus: / ) should always be uppercase.
:# Every other word should be lowercase except for proper nouns, names and common initialisms.
 
* Avoid including characters outside of ASCII alphanumerics. Try to make your task title easily type-able on a standard US keyboard.
 
There is substantial leeway in these rules, and some are subject to interpretation, but the closer you can come to following them, the easier it will be all-around.
 
===Draft vs non-draft===
Not all tasks are immediately ready to be thrown at the casual Rosetta Code participant. Some need a review or draft phase before they're in good shape.
* For a non-draft task, one would use [[Template:Task]] by putting '''[[Template:Task|<nowiki>{{tmpl|task}}</nowiki>]]''' at the top of the page.
* To note that a task is a draft, use [[Template:draft task]], by putting '''[[Template:draft task|<nowiki>{{tmpl|draft task}}</nowiki>]]''' at the top, rather than '''<nowiki>{{{tmpl|task}}}</nowiki>'''. If this is your first task, you should probably just start with a draft.
 
It's up to you to decide which you start with, but another community member may choose to change your created task to a draft. If there is some question on the general suitability of the task then create a draft task and discuss the reason for it being a draft in the talk page. This will warn potential contributors that there may be substantial changes in the task description whilst still in draft status.
Line 12 ⟶ 37:
====Reasons for draft status====
Reasons for draft status might include, but not be limited to:
* '''The task is too large.''' If a task can accomplish the same goals with a smaller spec, it probably should.
* A task that is too large.
* A'''The task that is too general,''' andleading soto hardcode examples which are particularly difficult to compare implementations.
* A'''The task that may beis too specific and so only,''' implementable by atoo singlefew languagelanguages.
 
===Task focus inclusion===
Generally speaking, the goal is to address a problem a programmer may face or want to think about. These include (but aren't strictly limited to):
* Practical problems
* Problems which demonstrate concepts
* Simple entertainment.
 
====Things to try for====
As for discouraged areas, remember that Rosetta Code is a tool of education, not a code repository. "Code golf", or the finding of the absolute most succinct expression of a solution as its own goal, is rarely idiomatic or practical use of the languages in question, and so is also difficult to justify in a demonstrative context.
Generally speaking, '''the goal is to address a problem a programmer may face or want to think about.''' These include (but aren't strictly limited to):
* '''Practical problems.''' These are problems with may occur regularly in practical application of programming languages, or at least are within the target domain of the language.
* '''Problems which demonstrate concepts.''' These are problems which attempt to highlight particular features, patterns or ideas in programming, and tend to contrast different languages' approaches to solving problems.
* '''Entertainment.''' Some tasks (see [[RCRPG]] or [[24 game]]) are created primarily for entertainment purposes, and represent an aggregate challenge of smaller problems.
 
TheAs a common theme, across '''all tasks must beseek increasingto increase competence and understanding of the tools in question''', by example or by annotated counterexample, if necessary.
 
===Task=Things focusto exclusionavoid====
* '''Don't require a specific language.''' Tasks which specify a particular language will not tend to achieve many useful comparisons or solutions, as languages are the richest resource on Rosetta Code. If your personal goal is to create a task which highlights a feature of a particular language, where that feature is unique or extraordinarily rare, don't create a task where that feature is ''required'' to solve the task. Instead, create a task that can be solved using a variety of means, but where that feature can greatly help in solving it. You may wish to highlight a unique feature of a particular language (yes, there are specific language advocates on Rosetta Code, and that's fine), but nobody will see that feature's usefulness if there are very few other languages for them to compare against.
'''A task should not be so specific as to invoke a particular language as being the only one allowed to solve a task.''' Tasks which specify a particular language will not tend to achieve many useful comparisons or solutions, as languages are the richest resource on Rosetta Code.
* '''Don't require exceedingly rare features.''' Requiring unique language features, or rare combinations of features, leads to the same problems as requiring a specific language.
 
** The caveat to the above, of course, is that '''best-effort solutions are often fine''' Some example solutions can fudge the spec without being inappropriate. ''"This isn't exactly possible in Ayrch, but something practical solving the language's idiomatic analog would be..."''
'''A task should also not be so specific with its other requirements that there is only one language capable of solving it.''' Specifically requiring language features et al such that it is unlikely that there would be multiple nominally-distinct languages that can satisfy the task requirements is equivalent to invoking a specific language, and so leads to the same problems.
***Think carefully about adding a later partial solution to a task if a working, full solution exists.
 
***When giving a best effort solution then state near its top, just what aspects of the task are not implemented, to avoid later editors marking the example as incorrect.
A caveat, however, is that '''best-effort solutions''' ("this isn't exactly possible in Ayrch, but something practical solving the language's idiomatic analog would be") '''are often fine''', so a task writer may find that styles "use technique X to solve problem" and "solve problem using technique X" may need to be interchanged to make a useful number of solutions possible.
***Consider the removal of a prior partial solution to a task when adding a new full solution to the task.
* '''Avoid creating tasks seeking the smallest possible solution.''' Code golf, or the finding of the absolute most succinct expression of a solution as its own goal, is not often an idiomatic, practical or comprehensible use of the language in question, and so is difficult to justify in a demonstrative context. Strokes are not points. For now, the only exception to this rule is [[Code Golf: Code Golf]]. If there is a case to be made for another exception, please use the prefix "Code Golf:" when creating the page.
* '''Avoid creating tasks seeking the fastest possible solution.''' Optimized code is rarely easy to read, and is often exceptionally complex as something to learn from. However, provided it does not make the overall section for the language too long, users may provide a more-optimal solution as an alternative solution to a particular task so that learners can compare it to the “optimized for clarity to people” version that should be the main solution for the language. (We also do not want to see the site devolving into “my language is faster than yours” silliness.)
 
===Basic information===
A task needs a few basic components. It neeedsneeds a '''simple description of the problem'''. Having a solution to the task allows you to tune the task description such that the run times and/or size of outputs are reasonable.
 
'''Inline references to specifically-related information''' are important. While offsiteoff-site links are often necessary (if only for appropriate citation), enough cited, excerpted information should be included such that the task may still be solved.
 
Where relevant, '''sample input''' should be included; it gives task solvers something to work with.
 
If your task requires a '''wordlist''' to be used with / tested against, it may be worthwhile specifying [[Wordlists|one of the commonly used]] ones to make it easier for other entry authors to fulfil and make results more uniform so different implementations can be more easily compared.
 
===Example code===
It is usually a good idea to '''have at least one example implementation completed, tested, and working''' ''before'' you start writing the description of the task, as well as '''a sample of correct output.''' It is usually a good idea if this first example shows its output; even if it isn't strictly necessary for the completion of the task, it helps other implementers understand the task and what they need to do.
 
In short, solve your own task. Show us how it's done.
 
==Additional information==
===Semantic annotations===
If your task invokes particular concepts (and it should; that's part of what a task is supposed to do), these should be marked with semantic notation. This will help better organize your task on Rosetta Code.

===Lurk!===
'''Read existing task descriptions''', and model yours after ones you like. If you follow the Recent Changes feed, you can watch the creation of one, live. Alternately, you might take a look at the edit history of existing tasks (and their talk pages), to get a feel of the process and the (unwritten) "house style."

===Jargon===
It helps to '''explain jargon''', as about the only common jargon that's likely be understood would be in the fields of programming or computer science&emdash;and even that's not guaranteed (this is an educational site, after all). Be especially aware of unexplained maths jargon, and watch the talk page and other implementations for signs that the task description may not be sufficiently clear.
