CZ:Code

This page contains standards and regulations related to Code subpages.

What are Code pages?

In these pages, users should upload the codes used to create CZ articles; especially tables and images. The code can be a scrypt designed for some specific operation system interface, as well as source in some of widely used programming languages: Postscript, Latex, Mathematica, Maple, Matlab, C++, Fortran, Assembler, etc.

Purpose

The goal of uploading of the codes is to allow any user to repoduce (id est, to check) the content of pictures and tables used in the CZ articles and verify them before to use. However, the codes may have also their independent meaning; they can be prototypes of generators of articles which are not posted in CZ.

Heading and format standards

Usually, the code is easier to read, if it is formatted as sequence of lines. In order to provide such formatting, each new line should begin with spacebar (character with decimal ascii number 32). At the header, it desirable to specify, what does the code do. It may be good idea, to specify the header as a "comment" in such a way, that it has no need to be removed before the compillation or execution of the code. All the codes are supposed to be in ascii; special unicode characters are allowed only if their use is essential, for example, illustrating a text in a foreign language. In particular, the Mathematica and Maple codes should be converted to ascii (plain text) before saving.

Guidelines for editing

Editing of codes after the last test-run is not recommended at all. Small error (for example, O instead of 0, or I instead of |, any specific unicode character that look identical to some ascii character) may affect the execution of code, while is difficult to detect at the visual revision.

Content Policy

The proof of significance of a code is that it generates some content, used in CZ. It is desirable to indicate, what pictures of tables were generated using the code. If used many times, it may worth to indicate the tree. Such a specification may look like a poem This Is the House That Jack Built, being something like this:

This code is Programs/FFT/simple/FFT.cin

That is used as a function, is inputted in

Programs/FFT/example.cc to generate the file

File:Fast Fourier Transform figure 3version02.jpg that is used, for a while

by the Fast Fourier Transform

by Fourier Analysis

by Periodic Functions

and by Table 1 in the article

Uniform convergence of series

... and so on. (Now some of files mentioned above are absent, but they may appear in future.)

Such an indication (if all clickable) makes it easy to check that the code is essential for the CZ, and without such a content, the encyclopedy cannot be considered as self-consistent.
