Static Variables

Static variables are variables that are set by the system in a certain context and typically contain values of certain environment parameters in this context. Static variables, like arguments, can be used only for reading, you can not set or change them. Also, static variables can not be used in data substitution, in contrast to variables and arguments.

Static variables created in a specific context are available in all valid contexts, and also are context-dependent.

The following static variables are currently available:

Variable	Description	Context
lastUrl	URL of last loaded page	All
url	URL of current page	Page, Block, Form
responseCode	Current HTTP request server response code	Page, Block, Form
filename	Last saved file or image filename	All
object_saved	If object has been saved to the DB, this variable gets value "yes". If object has been skipped (when object is saved in update mode), value will be "no".	All
pool_ignored	Contains number of duplicate URLs that were ignored by the link_add command.	All

Despite the fact that static variables are available in practically all contexts, you can use them only in a block context, because the register exists only in a block context and the only command for static variables works with the register.

Below is an example of using a static variable url:

          ---
config:
    agent: Chrome
do:
- walk:
    to: http://www.somesite.com
    do:
    - find:
        path: body
        do:
        - static_get: url
        - variable_set: page_url # now we have value http://www.somesite.com in the variable with name `page_url`
