\chapter{Introduction}
|
||||
|
||||
JET will pass through the untagged areas to the output without any
|
||||
modifications. Data contained within the tags may modify their
|
||||
containers before placing any output. The space taken by the tag
|
||||
itself is not passwed to the output and will not appear in the output.
|
||||
itself is not passed to the output and will not appear in the output.
|
||||
|
||||
Skip Blank Lines options on containers will skip passing any blank
|
||||
lines or line containing only whitespace to the output.
|
||||
|
||||
\chapter{Tags}
|
||||
\chapter{Tags and Attributes}
|
||||
|
||||
XML style tagging is used to insert functions and other behaviors into
|
||||
the script. As the document contents are output a tag may be inserted
|
||||
to perform the desired function and affect the output.
|
||||
|
||||
Tag attributes are used to pass parameters into the operations and
|
||||
functionality for each tag.
|
||||
|
||||
Outputting a database from mysql may be performed using the <mysql> tag
|
||||
in combination with the <ifrow>, <whilerow> and <sql> tags.
|
||||
|
||||
|
||||
\chapter{Variables and Variable Types}
|
||||
|
||||
|
||||
\chapter{Expressions}
|
||||
|
||||
Expressions are used to perform complicated calculations (arithmetic), perform
|
||||
comparisons between values (boolean), manipulate strings (string) or
|
||||
perform operations on dates (date).
|
||||
|
||||
\section{Functions and Operators}
|

|
||||
\subsection{left(string, number-of-characters)}
|
||||
|
||||
\subsection{substring(string, start-position, number-of-characters}
|
||||
|
||||
Use the substring operation to extract a portion of a string and return
|
||||
the value as a string.
|
||||
|
||||
\chapter{Common Gateway Interface Features}
|
||||
|
||||
JET extension tags provides options for enabling the processing of
|
||||
data using the Common Gateway Interface (CGI) specification used by
|
||||
Apache and NGINX as well as other HTTP server applications. This makes
|
||||
JET a powerful tool for creating web interfaces and API handler
|
||||
environments for various javascript frameworks as well as just native
|
||||
HTML style interaction.
|
||||
|
||||
To enable the CGI features within a requested document you can specify
|
||||
the cgi="true" attribute on a <jet> tag containing the document or
|
||||
<jet /> tag contained within the document.
|
||||
|
||||
When you enable the CGI interface the script will look for specific
|
||||
environment variables used to retrieve the input data from the browser
|
||||
interface and automatically provide these values to the JET scripting
|
||||
using the variables interface. There are currently three supported
|
||||
data formats or content types through this interface. These content
|
||||
types are:
|
||||
|
||||
formdata/urlencoded
|
||||
mutipart/formdata
|
||||
text/json
|
||||
|
||||
|

\chapter{Tag Reference}
|
||||
|
||||
This chapter will cover all the tags and parameters required to
|
||||
perform the operations that JET provides.

\section{call}
|

|
||||
Use the call tag to evoke an executable file from a jet script.

\section{comment}

Use the comment tag to create a section in the jet script that is

Use the comment tag to create a section in the jet script that can be
|
||||
used for making comments and is ignored by the jet reader.

\section{mysql}
|

Use the mysql tag to specify parameters for connecting to a mysql
