Sometimes I run unit tests on ClarionMagLibrary (CML) code, and sometimes on non-CML code. When I run the latter I may or may not want to include the CML library, but when I run the former I usually want to compile the code directly so I don't have to remember whether I'm testing a library change or a unit test change. It's also usually an advantage to test against a local compile until I'm sure everything is working - that way I'm not breaking any code that does use the library.
I got tired of setting the necessary project define in my project, so I added a couple of lines to the global extension template. Line 3 is a new prompt, which has a related #Enable/#EndEnable section that wraps the original "Include the ClarionMag library" prompt.
#EXTENSION(TestSupportIncludes,'Add global includes for test support'),APPLICATION,DESCRIPTION('[ClarionTest] Global Includes for Test Support') #DISPLAY #Prompt('Compile ClarionMag Library source',Check),%CompileClarionMagLibrarySource,At(10,,180) #Enable(%CompileClarionMagLibrarySource=%false) #Prompt('Include the ClarionMag library',check),%IncludeClarionMagLib,default(%true),At(10,,180) #EndEnable #PROMPT('Generate help comments',CHECK),%ShowHelpComments,Default(%False),At(10,,180) #DISPLAY('You can add the name of your Class .INC files below. The INCLUDE directive will be added for you.'),AT(10,,180,24) #BOXED('Class .INC Files') #PROMPT('Class .INC File:',@S200),%TestClasses,MULTI('Class .INC File') #ENDBOXED #!********** #ATSTART #IF(VAREXISTS(%TestGroups) AND ITEMS(%TestGroups) = 0) #ADD(%TestGroups,'Default') #ENDIF #If(%CompileClarionMagLibrarySource) #Set(%IncludeClarionMagLib,%False) #PDefine('_Compile_CML_Class_Source_',1) #Else #PDefine('_Compile_CML_Class_Source_',0) #EndIf #ENDAT #AT(%CustomGlobalDeclarations),where(%IncludeClarionMagLib) #PROJECT('CMagLib.lib') #ENDAT
In the #ATSTART section I added some code to set the project defines, using the #PDEFINE statement. The help says this about #PDEFINE:
#PDEFINE ( symbol, value )
#PDEFINE | Adds a #pragma statement to the project system. |
symbol | A symbol that contains a pragma identifier. |
value | The value that is associated with the symbol to determine whether to omit or compile code that is enclosed using the OMIT or COMPILE directives. |
The #PDEFINE statement adds a #pragma (compiler option) statement to the project system. A pragma is added to the project file in the form of symbol => value.
Example:
#IF (%DemoVersion)
#PDEFINE('_DEMO_',1)
#ELSE
#PDEFINE('_DEMO_',0)
#ENDIF
And here are the new template prompts:
There's one possible problem here, which is that although the Include the ClarionMag library prompt is disabled, if checked it remains checked, and that looks confusing. The fix is to write some template code that clears the checkbox via the WhenAccepted attribute:
#Prompt('Compile ClarionMag Library source',Check),%CompileClarionMagLibrarySource,At(10,,180),WhenAccepted(%ClearCompileClarionMagLibrarySourceIfNecessary(%CompileClarionMagLibrarySource,%IncludeClarionMagLib)) ... #Group(%ClearCompileClarionMagLibrarySourceIfNecessary,*%pCompileClarionMagLibrarySource,*%pIncludeClarionMagLib) #If(%pCompileClarionMagLibrarySource=%true) #Set(%pIncludeClarionMagLib,%False) #EndIf
Notice that the #Group receives parameters by address - if you pass the parameters by value they will not be updated in the prompt section, and because the variables aren't globally declared they must be passed.
This introduces another problem, however, which is that if I originally needed the CML but for testing compile it, when I uncheck the first option I've lost the second one. So the better option I think is to remove the WhenAccepted attribute and hide the second option when the first one is selected.
Hiding #PROMPTs is a bit non-obvious. You need to wrap the prompt in a #BOXED/#ENDBOXED section with a WHERE clause:
#Boxed,Where(%CompileClarionMagLibrarySource=%false) #Prompt('Include the ClarionMag library',check),%IncludeClarionMagLib,default(%true),At(10,,180) #EndBoxed
The second prompt now disappears when the first is selected:
And of course the all-important project define is set to either 0 or 1 according to the first option:
