We recommend to use IFDEF-checks, for example:
{$IFDEF EUREKALOG}
uses
EModules;
{$ENDIF}
{$IFDEF EUREKALOG}
// Compiled with EurekaLog
CurrentEurekaLogOptions. // ...
{$ENDIF}
Alternatively there are functions (in EBase unit) like:
function IsEurekaLogInstalled: Boolean;
function IsEurekaLogActive: Boolean;
function IsEurekaLogActiveInThread(const AThreadID: Cardinal = 0): Boolean;
EurekaLog is considered to be active (in other words: will do its work) only if all of the following are true:
| • | EurekaLog was compiled in (EUREKALOG symbol was defined, EurekaLog's units were added, IsEurekaLogInstalled returns True); |
| • | EurekaLog is enabled globally (IsEurekaLogActive returns True); |
| • | EurekaLog is enabled in the current thread (IsEurekaLogActiveInThread returns True). |
For example:
{$IFDEF EUREKALOG}
if IsEurekaLogActive and
IsEurekaLogActiveInThread then
// EurekaLog is compiled in and is enabled
raise Exception.Create('will be handled by EurekaLog')
else
// EurekaLog is compiled in, but is disabled
raise Exception.Create('will be handled by RTL/VCL');
{$ELSE}
// EurekaLog is not compiled in
raise Exception.Create('will be handled by RTL/VCL');
{$ENDIF}
Notes:
| • | EBase unit can be included into any application - even without EurekaLog; |
| • | IsEurekaLogActive will return False when IsEurekaLogInstalled returns False, so it is usually not required to call IsEurekaLogInstalled. |
You can also detect if EurekaLog was disabled during compilation by looking at output of your compilation:
IDE's Messages / Build window - this is output when EurekaLog is disabled
