of them are only hastily set up, so I believe that as long as the time taken, these problems can be properly resolved. In addition, the language specification is likely to change over time, such as adding new keywords, types, and syntax when necessary. So there is no unified conclusion about the documents and other materials. However, if you are interested in this language, the initial tools have been published on the basis of the Apache license.

No. 7: zimbu
As a product of Bram moolenaar, zimbu has absorbed the features of various previous languages and aims to become a fast, concise, lightweight, easy-to-read language that can be applied from GUI applications to the OS kernel. Because zimbu has multiple features, the syntax itself is unique. It not only has expressions and operators like C, but also has its own keywords, data types and program
I wrote a C + + class that implements most of the BERTLV operations, with the following code:Https://github.com/vsuu/elib/blob/master/elib2014/BerTLV.hThis implementation uses iterators to unify arrays and streams, so this class can accept array input or stream input.Examples of operations:voidTESTBERTLV () {Try{tagtype tag; Char* Tagstr ="\x70\x80"; Char* TAGSTR1 ="\x1f\x70"; BERTLV::P arsetag (tagstr, Tagstr+2, tag); ASSERT (Tag==0x70); BERTLV::P arsetag (TAGSTR1, Tagstr1+2, tag); ASSERT (Tag=

This peculiar language absorbs elements and compositions from various other languages, and it is the crystallization of the wisdom of Bram Moolenaar. Bram Moolenaar is the creator of the Vim text editor. This language is planned to be fast, concise, portable, and readable. Its syntax is unique, distinctive, but rich in functionality.

Description
StartingXAnd repeatedly multiplyingX, We can computeX31 with thirty multiplications:
X2 =X×X,X3 =X2 ×X,X4 =X3×X,...,X31 =X30 ×X.
The operation of squaring can be appreciably shorten the sequence of multiplications. The following is a way to computeX31 with eight multiplications:
X2 =X×X,X3 =X2 ×X,X6 =X3×X3,X7 =X6×X,X14 =X7×X7,X15 =X14×X,X30 =X15 ×X15,X31 =X30 ×X.
This is not the shortest sequence of multiplications to computeX31. There are always ways with only seven multiplica
