Contributing Exercise Solutions

If you want to contribute to exercise solutions, you need to know the structure of SNIPPET tags. Here are the components:

• NAME: optional; at most one; allows other SNIPPETs to refer to and "require" this program. Example: <NAME>my_program</NAME>
• REQUIRES: optional; multiple allowed; allows this SNIPPET to recursively include other snippets by including their name. Example: <REQUIRES>my_other_program</REQUIRES>. All "required" programs are placed before the snippet when displayed in the Source Academy. The "required" programs are not displayed in the textbook editions.
• EXAMPLE: optional; at most one; allows this SNIPPET to recursively include another SNIPPET by including its name. Example: <EXAMPLE>my_example_program</NAME>. The "example" program is placed after the snippet when displayed in the Source Academy. The "example" program is not displayed in the textbook editions.
• SCHEME: optional; here goes the Scheme version; feel free to ignore
• JAVASCRIPT: required for all practical purposes: Include the JavaScript version here.

Attributes of SNIPPET tags include:

• HIDE = yes: (default: no) The program is not displayed in the textbook editions.
• LATEX = yes: (default: no) The program contains LaTeX formulas using $$ syntax.
• EVAL = no: (default: yes) The program is not clickable.
