[ file->openWriteOnly ]
The [file->openWriteOnly] method can be called on a [file] object to open a file for writing only. If a path is already stored in the [file] object, it can be called with no parameters. It can also be called with a string specifying the path to a file. If it is called with a path to a file, that new path becomes the path for the [file] object, overriding any previous path.
If [file->openWriteOnly] is called with a file path, it can also take an optional boolean parameter that specifies whether or not to create the file if it doesn't already exist. The default is true which means the file will be created if it does not already exist.
- Syntax
local(f) = file(...)
#f->openWriteOnly
local(f) = file
#f->openWriteOnly('/path/to/file.txt')
local(f) = file
#f->openWriteOnly('/path/to/file.txt', false)Examples
- Beginner
Create a new file and put some text in it
The code example below assumes that the file 'test.txt' doesn't exist. The code will create that file and insert the "Is there a problem with the earth's gravitational pull?" into it.
Code
local(my_file) = file('test.txt')
#my_file->doWithClose => {
#my_file->openWriteOnly
#my_file->writeString('"Is there a problem with the earth\'s gravitational pull?"')
}
