4 Errortrace Library
| (require errortrace/errortrace-lib) | |
| package: errortrace-lib | |
The errortrace/errortrace-lib module exports all of the
exports of errortrace, plus a few more. It does
not install any handlers.
The additional exports are as follows:
procedure
(errortrace-compile-handler stx immediate-eval?) → compiled-expression? stx : any/c immediate-eval? : any/c
Compiles stx using the compilation handler that was active
when the errortrace/errortrace-lib module was
executed, but first instruments the code for Errortrace information.
The code is instrumented only if
is the same as when the
errortrace/errortrace-lib module was executed. This
procedure is suitable for use as a compilation handler via
current-compile.
Produces a compile handler that is like
errortrace-compile-handler, except that the code that
it produces is instrumented if the value of
is the same as when the original thunk is invoked.
In addition, when the thunk is invoked, it uses namespace-attach-module to attach the errortrace/errortrace-key module and the '#%kernel module to the current-namespace.
procedure
(errortrace-error-display-handler string exn) → void? string : string? exn : exn?
Displays information about the exception; this procedure is suitable
for use as an error display handler.
procedure
(errortrace-annotate stx) → any/c
stx : any/c
Macro-expands and instruments the given top-level form. If the form is
a module named errortrace-key, no instrumentation is
applied. This annotation function is used by
errortrace-compile-handler.
procedure
(annotate-top stx phase-level) → any/c
stx : any/c phase-level : exact-integer?
Like errortrace-annotate, but given an explicit phase level
for stx; (namespace-base-phase) is typically the
right value for the phase-level argument.
Unlike errortrace-annotate, there no special case for a module named errortrace-key. Also, if stx is a module declaration, it is not enriched with imports to explicitly load Errortrace run-time support.
