- "WITH-COMPILATION-UNIT ({Key Value}*) Form*
- This form affects compilations that take place within its dynamic extent. It
- is intended to be wrapped around the compilation of all files in the same
- system. These keywords are defined:
-
- :OVERRIDE Boolean-Form
- One of the effects of this form is to delay undefined warnings
- until the end of the form, instead of giving them at the end of each
- compilation. If OVERRIDE is NIL (the default), then the outermost
- WITH-COMPILATION-UNIT form grabs the undefined warnings. Specifying
- OVERRIDE true causes that form to grab any enclosed warnings, even if
- it is enclosed by another WITH-COMPILATION-UNIT.
-
- :SOURCE-PLIST Plist-Form
- Attaches the value returned by the Plist-Form to internal debug-source
- information of functions compiled in within the dynamic contour.
- Primarily for use by development environments, in order to eg. associate
- function definitions with editor-buffers. Can be accessed as
- SB-INTROSPECT:DEFINITION-SOURCE-PLIST. If multiple, nested
- WITH-COMPILATION-UNITs provide :SOURCE-PLISTs, they are appended
- togather, innermost left. If Unaffected by :OVERRIDE."
+ "Affects compilations that take place within its dynamic extent. It is
+intended to be eg. wrapped around the compilation of all files in the same system.
+
+Following options are defined:
+
+ :OVERRIDE Boolean-Form
+ One of the effects of this form is to delay undefined warnings until the
+ end of the form, instead of giving them at the end of each compilation.
+ If OVERRIDE is NIL (the default), then the outermost
+ WITH-COMPILATION-UNIT form grabs the undefined warnings. Specifying
+ OVERRIDE true causes that form to grab any enclosed warnings, even if it
+ is enclosed by another WITH-COMPILATION-UNIT.
+
+ :POLICY Optimize-Declaration-Form
+ Provides dynamic scoping for global compiler optimization qualities and
+ restrictions, limiting effects of subsequent OPTIMIZE proclamations and
+ calls to SB-EXT:RESTRICT-COMPILER-POLICY to the dynamic scope of BODY.
+
+ If OVERRIDE is false, specified POLICY is merged with current global
+ policy. If OVERRIDE is true, current global policy, including any
+ restrictions, is discarded in favor of the specified POLICY.
+
+ Supplying POLICY NIL is equivalent to the option not being supplied at
+ all, ie. dynamic scoping of policy does not take place.
+
+ This option is an SBCL-specific experimental extension: Interface
+ subject to change.
+
+ :SOURCE-PLIST Plist-Form
+ Attaches the value returned by the Plist-Form to internal debug-source
+ information of functions compiled in within the dynamic extent of BODY.
+
+ Primarily for use by development environments, in order to eg. associate
+ function definitions with editor-buffers. Can be accessed using
+ SB-INTROSPECT:DEFINITION-SOURCE-PLIST.
+
+ If an outer WITH-COMPILATION-UNIT form also provide a SOURCE-PLIST, it
+ is appended to the end of the provided SOURCE-PLIST. Unaffected
+ by :OVERRIDE.
+
+ This is an SBCL-specific extension.
+
+Examples:
+
+ ;; Prevent proclamations from the file leaking, and restrict
+ ;; SAFETY to 3 -- otherwise uses the current global policy.
+ (with-compilation-unit (:policy '(optimize))
+ (restrict-compiler-policy 'safety 3)
+ (load \"foo.lisp\"))
+
+ ;; Using default policy instead of the current global one,
+ ;; except for DEBUG 3.
+ (with-compilation-unit (:policy '(optimize debug)
+ :override t)
+ (load \"foo.lisp\"))
+
+ ;; Same as if :POLICY had not been specified at all: SAFETY 3
+ ;; proclamation leaks out from WITH-COMPILATION-UNIT.
+ (with-compilation-unit (:policy nil)
+ (declaim (optimize safety))
+ (load \"foo.lisp\"))
+"
