lstrip¶

The lstrip filter is designed to remove leading whitespace characters from the beginning of a string.

Functionality

Strings: Takes a string as input.
Stripping: Removes any whitespace characters (spaces, tabs, newlines) from the start of the string.
Output: Returns a new string with the leading whitespace removed.

Syntax

    {{ input_string | lstrip }}

Arguments

The lstrip filter does not require any arguments.

Code Samples

Example 1: Removing Leading Spaces

    {% assign message = "This string has leading spaces." %}
    {{ message | lstrip }}

Output:

This string has leading spaces.

Example 2: Removing Leading Tabs and Newlines

    {% assign code = "\t\n  def function():\n    pass" %}

    {{ code | lstrip }}

Output:

def function():
pass

Empty Strings: If the input string is empty, the lstrip filter returns an empty string.
Strings Without Leading Whitespace: If the input string does not have any leading whitespace, the filter returns the original string unchanged.
Non-String Input: If the input is not a string, the lstrip filter might attempt to convert it to a string or return an error, depending on how Experience Builder handles type conversions.

The lstrip filter is a handy tool for cleaning and normalizing string data.
It is particularly useful when dealing with user input or data imported from external sources where leading whitespace might be present.
Combine it with rstrip to remove both leading and trailing whitespace, or with strip to remove whitespace from both ends in a single operation.
