set_content()

Usage

set_content(file, content[, encoding = "UTF-8"])

Description
Overwrites the contents of the given file with the given content.

Note
The encoding parameter is used when writing the data to the file. The default (UTF-8) rarely needs to be changed but can be very useful when working with binary strings. For example when using the to_excel() function.

Example

1. Simply overwrite file with static content

   set_content(first(find('File', 'name', 'test.txt')), 'New Content Of File test.txt')
   

2. Create new file with Excel content

   set_content(create('File', 'name', 'new_document.xlsx'), to_excel(find('User'), 'public'), 'ISO-8859-1')
   

3. Create a new file and retrieve the last 100 tweets from @structr
