[ file->openRead ]
The [file->openRead] method can be called on a [file] object to open a file for reading 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.
- Syntax
local(f) = file(...)
#f->openRead
local(f) = file
#f->openRead('/path/to/file.txt')Examples

Switching open file paths
The code below demonstrates the two different ways to call [file->openRead] and the effects on the [file] object's path.
Code
local(my_file) = file('/test.lasso')
#my_file->doWithClose => {^
#my_file->openRead
#my_file->path
'<br>'
#my_file->openRead('/index.lasso')
#my_file->path
^}Result
/test.lasso
/index.lasso
