%description
|
|
This module provides a syntax plugin that implements a block which executes
|
|
when the containing scope has finished.
|
|
|
|
It similar to features provided by other languages; Swift, Zig, Jai, Nim
|
|
and Odin all provide this. Note that while Go also provides a 'defer'
|
|
keyword, the semantics here are not the same. Go's version defers until the
|
|
end of the entire function, rather than the closest enclosing scope as is
|
|
common to most other languages, and this module.
|
|
|
|
The operation can be considered a little similar to an 'END' block, but
|
|
with the following key differences:
|
|
|
|
* A 'defer' block runs at the time that execution leaves the block it is
|
|
declared inside, whereas an 'END' block runs at the end time of the entire
|
|
program regardless of its location.
|
|
|
|
* A 'defer' block is invoked at the time its containing scope has finished,
|
|
which means it might run again if the block is entered again later in the
|
|
program. An 'END' block will only ever run once.
|
|
|
|
* A 'defer' block will only take effect if execution reaches the line it is
|
|
declared on; if the line is not reached then nothing happens. An 'END'
|
|
block will always be invoked once declared, regardless of the dynamic
|
|
extent of execution at runtime.
|
|
|
|
'defer' blocks are primarily intended for cases such as resource
|
|
finalisation tasks that may be conditionally required.
|
|
|
|
For example in the synopsis code, after normal execution the statement
|
|
handle will be finished using the '$sth->finish' method, then the database
|
|
will be disconnected with '$dbh->disconnect'. If instead the prepare method
|
|
failed then the database will still be disconnected, but there is no need
|
|
to finish with the statement handle as the second 'defer' block was never
|
|
encountered.
