Add Text from a StringBuilder to a ZIP Using AddSb

See more Zip Examples

This example demonstrates how to use the AddSb method to add text from a StringBuilder object as a file entry within a ZIP archive.

The text is converted to bytes using the specified character encoding before being stored in the ZIP archive.

This method is useful for dynamically generating text files entirely in memory without creating temporary files on disk.

    delete_CkZip $zip
    exit
}

# Create a StringBuilder containing text data.
set sb [new_CkStringBuilder]

CkStringBuilder_AppendLine $sb "Line 1: Hello World!" 1
CkStringBuilder_AppendLine $sb "Line 2: This text came from a StringBuilder." 1

# Add the StringBuilder contents as a UTF-8 text file
# stored in the ZIP archive as "docs/readme.txt".
set success [CkZip_AddSb $zip "docs/readme.txt" $sb "utf-8"]
if {$success == 0} then {
    puts [CkZip_lastErrorText $zip]
    delete_CkZip $zip
    delete_CkStringBuilder $sb

# Write the ZIP archive to disk and close it.
