$warn

pascal

{$warn}

is a local compiler directive controlling emission of certain messages during compile-time. Messages do not necessarily have to be warnings, but can be messages of any kind. The directive may also promote specific messages to errors.

The (local) compiler directives

pascal

{$warnings on}

and

pascal

{$warnings off}

may turn on or off emission of all warnings all together.

usage

pascal

{$warn}

requires a message label and a treatment option as arguments, like this:

pascal

{$warn 3250 off}

The numeric message label can be retrieved during compilation with the

bash

-vq

option supplied on the command-line (verbosity: show message numbers). Some messages and groups of messages have an alias, too, which can be seen in the table below.

Beside

pascal

{$warn 3019 on}

pascal

{$warn 3019 off}

and the shorthand notation

pascal

{$warn 3019 +}

and

pascal

{$warn 3019 -}

respectively,

pascal

{$warn}

may be used to promote messages to errors.

pascal

{$warn symbol_experimental error}

will make all, if any, [[Hint Directives|hints concerning

delphi

experimental

symbols]] become (non-fatal) errors. Depending on the selected error treatment, the compiler may stop compiling or continue, unless a threshold of errors has been reached.

Note, demoting messages to errors is not possible. A

pascal

{$fatal}

error will always be fatal.
