robot.variables package — Robot Framework 7.3.3.dev1 documentation

robot.variables package

Implements storing and resolving variables.

This package is mainly for internal usage, but utilities for finding variables can be used externally as well.

robot.variables.notfound module
robot.variables.notfound.variable_not_found(name, candidates, message=None, deco_braces=True)[source]

Raise DataError for missing variable name.

Return recommendations for similar variable names if any are found.

robot.variables.replacer module
class robot.variables.replacer.VariableReplacer(variables)[source]

Bases: object

replace_list(items, replace_until=None, ignore_errors=False)[source]

Replaces variables from a list of items.

If an item in a list is a @{list} variable its value is returned. Possible variables from other items are replaced using ‘replace_scalar’. Result is always a list.

‘replace_until’ can be used to limit replacing arguments to certain index from the beginning. Used with Run Keyword variants that only want to resolve some arguments in the beginning and pass others to called keywords unmodified.

replace_scalar(item, ignore_errors=False)[source]

Replaces variables from a scalar item.

If the item is not a string it is returned as is. If it is a variable, its value is returned. Otherwise, possible variables are replaced with ‘replace_string’. Result may be any object.

replace_string(item, custom_unescaper=None, ignore_errors=False)[source]

Replaces variables from a string. Result is always a string.

Input can also be an already found VariableMatch.

Represents a set of variables.

Contains methods for replacing variables from list, scalars, and strings. On top of ${scalar}, @{list} and &{dict} variables, these methods handle also %{environment} variables.
