-fixupmessages SELECTOR ( ';' ( is | replace | restrict ) )* ...

The -fixupmessages instruction is intended to fixup the errors and warnings. It allows you to remove errors and/or warnings, turn errors into warnings, and turn warnings into errors. With this instruction you can fail a build based on a warning or succeed a build that runs into errors.

The default of this instruction is to list a number of patterns. Any error or warning that matches this pattern is then removed. The following example will remove any error/warning that matches 'some error', 'another error', or 'and yet another error'.

-fixupmessages:  \
	some error, 
	another error, 
	and yet another error

The pattern is a SELECTOR, which makes it possible to do case insensitive matches, wildcards, literals, etc.

Syntax

The basic format of -fixupmessages is:

-fixupmessages ::= fixup ( ',' fixup ) *
fixup          ::= SELECTOR directive *
directive      ::= ';' ( restrict | is | replace )
restrict       ::= 'restrict:=' ( 'error' | 'warning' )
is             ::= 'is:=' ( 'ignore' | 'error' | 'warning' )
replace        ::= 'replace:=' <<text>> 

The value of a fixup clause is a globbing expression.

Directives

The following directives are supported:

• restrict: – By default, the fixup clause is applied to all errors and warnings. You can restrict its application to either errors or warnings specifying either restrict:=error or restrict:=warning.
• is: – By default an error remains an error and a warning remains a warning. However, if you specify the is: directive you can force an error to become a warning or vice versa. This can be very useful if you build fails with an error that you do not consider a failure.
• replace: – Replace the message with a new message. The replacement will be processed by the macro processor, the ${@} macro will contain the current message.

The -fixupmessages instruction is a merged property. This means that you can define it in many different places like for example in a file in cnf/ext. Just put an extension on the instruction. For example:

-fixupmessages.one: 'Some error'
-fixupmessages.two: 'Another error'

Examples

# Turn an error into a warning
-fixupmessages
  "Invalid character'; \
    restrict:=error;
    is:=warning
  
# Replace a message
-fixupmessages \
  "split";replace:=broken
  
# Ignore case by appending :i
-fixupmessages \
  "case insensitive:i"

# Wildcards
-fixupmessages \
  "prefix*suffix"

# Turn properties parser messages into warnings
-fixupmessages.parser: \
  "Invalid character in properties"; \
  "No value specified for key"; \
  "Invalid property key"; \
  "Invalid unicode string"; \
  "Found \\<whitespace>";
    is:=warning
