This repository contains AWS SDK code examples used in the public AWS documentation repositories.
The code examples are organized by programming language. For instance, all of the examples for the AWS SDK for Java Developer Guide are kept in the java directory.
Inside each of the language-specific directories, you'll find a README file that explains how to build and run the examples contained within it.
The example code inside the language-specific directories is organized by the AWS service abbreviation ("s3" for Amazon S3 examples, and so on).
If you plan to contribute examples for use in the documentation (the purpose of this repository), please read this section carefully so that we can work together more effectively.
Make sure that the code can be built and run. There's nothing more frustrating in developer documentation than code examples that don't work. Build the code and test it before submitting it!
Do not include personal account data, keys or IDs in your examples. Code should obtain access keys from the standard SDK credentials and config files, use environment variables or external data files, or query the user for this information.
Format code lines to 80 characters. Long lines can be enclosed in a scrollable box for HTML, but in a PDF build, long lines will often spill off the side of the page, making the code unreadable. If your code includes long text strings, consider breaking these into smaller chunks and concatenating them together.
Use short(er) variable names. To aid in readability and to help keep line length down, use short yet descriptive names for variables. Do not simply mimic class names when creating variables that represent an object of that class. It nearly always results in excessively long variable names, making it difficult to keep code lines within 80 characters.
Use spaces, not tabs, for indentation. Tabs are variable-length in most editors, but will usually render as 8 characters wide in printed documentation. Always use spaces to ensure consistent formatting in printed code.
You can ignore this rule for makefiles, which may require the use of tabs, but these are typically only used for building examples, and are not included in documentation.
Minimize the use of comments. Code is ignored for translation, so comments in code are not translated for the printed documentation's target language. Comments should not be needed in most code used for documentation, since the goal is clarity and ease of understanding. By making code self-explanatory, you'll make better code for documentation and reduce the need to add comments.
Place comments on separate lines from code. If you must add a comment for explanation or any other purpose, make sure that it's placed on a separate line from code (not inline). This allows readers of the source file to read the comment, yet it can be stripped out when including snippets from the file within documentation.
