Here, the use of static if , D's compile-time conditional construct, is demonstrated to construct a template that performs the same calculation using code that is similar to that of the function above:. In the following two examples, the template and function defined above are used to compute factorials.
The types of constants need not be specified explicitly as the compiler infers their types from the right-hand sides of assignments:. This is an example of compile time function execution. Ordinary functions may be used in constant, compile-time expressions provided they meet certain criteria:.
The std. String mixins, combined with compile-time function execution, allow generating D code using string operations at compile time. This can be used to parse domain-specific languages to D code, which will be compiled as part of the program:. D supports functional programming features such as function literals, closures, recursively-immutable objects and the use of higher-order functions. There are two syntaxes for anonymous functions, including a multiple-statement form and a 'shorthand' single-expression notation: [8].
There are two built-in types for function literals, function , which is simply a pointer to a stack-allocated function, and delegate , which also includes a pointer to the surrounding environment. Type inference may be used with an anonymous function, in which case the compiler creates a delegate unless it can prove that an environment pointer is not necessary.
Likewise, to implement a closure, the compiler places enclosed local variables on the heap only if necessary for example, if a closure is returned by another function, and exits that function's scope. When using type inference, the compiler will also add attributes such as pure and nothrow to a function's type, if it can prove that they apply. Other functional features such as currying and common higher-order functions such as map, filter, and reduce are available through the standard library modules std.
Memory is usually managed with garbage collection, but specific objects may be finalized immediately when they go out of scope. Explicit memory management is possible using the overloaded operators new and delete , and by simply calling C's malloc and free directly.
Garbage collection can be controlled: programmers may add and exclude memory ranges from being observed by the collector, can disable and enable the collector and force either a generational or full collection cycle. SafeD [14] is the name given to the subset of D that can be guaranteed to be memory safe no writes to memory that were not allocated or that have already been recycled.
Functions marked safe are checked at compile time to ensure that they do not use any features that could result in corruption of memory, such as pointer arithmetic and unchecked casts, and any other functions called must also be marked as safe or trusted.
Functions can be marked trusted for the cases where the compiler cannot distinguish between safe use of a feature that is disabled in SafeD and a potential case of memory corruption.
Initially under the banners of DIP [16] and DIP25 [17] Now part of the language specification [18] , D provides protections against certain ill-formed constructions involving the lifetimes of data. The current mechanisms in place primarily deal with function parameters and stack memory however it is a stated ambition of the leadership of the programming language to provide a more thorough treatment of lifetimes within the D programming language [19].
Within safe code, the lifetime of an assignment involving a reference type is checked to ensure to the lifetime of the assignee is longer than that of the assigned. When applied to function parameter which are either of pointer type or references, the keywords return and scope constrain the lifetime and use of that parameter. C's application binary interface ABI is supported, as well as all of C's fundamental and derived types, enabling direct access to existing C code and libraries.
D bindings are available for many popular C libraries. Additionally, C's standard library is a part of standard D. The D programming language has an official subset known as 'Better C' [22]. This subset forbids access to D features requiring use of runtime libraries other than that of C. Accessed via- on all current implementations - the '-betterC' flag during compilation, Better C may only call into D code compiled under the same flag and linked code other than D but code compiled without the Better C option may call into code compiled with it: This will, however, lead to slightly different behaviours due to differences in how C and D handle asserts.
Walter Bright started working on a new language in D was first released in December [1] and reached version 1. Dissatisfied with Phobos, D's official runtime and standard library, members of the D community created an alternative runtime and standard library named Tango. The first public Tango announcement came within days of D 1. Being a community-led project, Tango was more open to contributions, which allowed it to progress faster than the official standard library.
At that time, Tango and Phobos were incompatible due to different runtime support APIs the garbage collector, threading support, etc. This made it impossible to use both libraries in the same project.
The existence of two libraries, both widely in use, has led to significant dispute due to some packages using Phobos and others using Tango. In June , the first version of D2 was released. The first version of the language has been placed in maintenance, only receiving corrections and implementation bugfixes.
D2 introduced breaking changes to the language, beginning with its first experimental const system. D2 later added numerous other language features, such as closures, purity, and support for the functional and concurrent programming paradigms.
D2 also solved standard library problems by separating the runtime from the standard library. It would seem brutal not to, and I plan on doing it. Not to mention that I went to the trouble of giving them real character sheets and sleeved power cards. Belial was such a bs character, impossible to recreate in CB until 2nd level, when you could take the Hybrid Talent feat to get Darkspiral Aura.
After all they want everyone to have the same shared experience. One thing to remember with tweaking the encounters is that Dark Sun is a tougher world than others, so the encounters may seem harder.
However, each of the PCs has an extra encounter power made available through the theme system. This may or may not help to balance things out. Time will tell. A fresh set of reinforcements, with similar attack abilities arrives every five rounds. And the old "chaotic neutrality" of self-styled outlaw "free spirits" is unlike the "primordial"'s world of ever-changing matter without thought or meaning.
The historic neutrality of druids has found a more true-to-life expression as the mission to keep the natural world safe from destruction by either natural disaster the primordials or the ideologies of humankind the gods. During my own formative years, many of us saw the global conflict as between Chaotic Good "Woodstock Nation" and Lawful Evil the totalitarian regimes.
I have retained these options. During the "Dark Ages" -- the default setting for Fourth Edition -- civilization with firm justice was the only hope for a better world. Yet tyranny, slavery, and law as the means of oppression were all-too-real. And even if the utopian dreams of hippies were as impossible as "chaotic good" elves, unicorns, or flying horses, people still cherish the medieval tales of Robin Hood and his benevolent outlaws.
You decide. These model builds can be made by choosing the base class and slightly hand-editing. The modifications made to the PH1 material since its publication have been noted on the character sheets. Thanks for understanding. Multiclass: Bards: If you want to to paragon multiclass, choose 1st from here. No hybrid multiclassers.
Hand-edit your sheet! Good luck! Hand-edit the character sheet. I have not allowed "Master at Arms" to be taken with any specific weapon expertise feat. Write an extra on your character sheet. Rituals: Clerics start with Gentle Repose and one other first-level. Wizards start with three first-level rituals.
Bards start with two first-level rituals, one of them a bard ritual. Druids start with Animal Messenger and one other first-level. Invokers start with Hand of Fate and one first-level. All ritual casters learn more over time. You may qualify for rituals from other sources but they won't show if you are not a ritual caster.
Please hand-edit -- Sorry! Three if you have "Wild Talent Master". Under Development!

Additional equipment Sir Galahad Pressing this button should generate a character sheet on a new screen, suitable for printing. For some browsers, the best way to save this character sheet is to select "print" and save in. Like Jonathan, this is totally bookmarked. I prefer my own Monk class though. Yeah, shameless plug. Great resources! Thanks for taking the time to compile the list. Scott: Cool. I thought I had seen another Monk class out there. I think there is a barbarian class floating around too.
Labs: There are quite a few new and revamped classes floating around — the Wizards forum had a Ki I think defender, the Wulin Xia or something like that that was really good.
This is pretty impressive. A nice collection of useful tools and miscellaneum. I though my ten member UT3 clan was impressive. I to have been struck the the readerneglection virus due to a bit of DIY on my site.
