Re: [cdt-dev] Managed Build Macros proposal - Feedback
|
Mikhail,
I had a look at the proposal and it
looks good. Sorry I am relatively late with this. I have a few questions
for clarification.
Regards
-- Lars
[Section1.4]
Q1: It is not clear to me what
the difference and interactions between the Build Macro Provider and a
Macro Supplier are. Maybe this question will be answered in a later section
of the document.
[Section1.5]
Q2: Got a missing table here
[Section2.1, item 4 "The Currently
selected file....]
Q3: I just wanted to check whether
this restriction is a concious decision not to support this for CDT3.0.
I believe that in principle you should be able to use the "C/C++ build"
property page in this case.
[Section3.3]
Q4: It is not clear how a tool
integrator provides file-context macros. Is there a macro provider for
this? Or are these read only-macros which I can define only. But if I have
attributes of the form "macro<MacroName>Value = <thisValue>"
as children of the MBS builder element, how can the macros have different
values for different selected files? Maybe I misunderstood what file specific
macros are for.
[Section3.4]
Q5: Maybe you want to add a further
entry here, e.g. variableAssignment, which defines how a value is assigned
to a build macro. In GNU make alone you could either use "macro =
value" or "macro := value". The latter option is more efficient.
So you may want introduce a syntax which allows defining this.
[Section 3.6.1 and 3.6.2]
Q6: Are the build macro suppliers
called every time the UI and build file generator needs the value of a
build macro? Or are these cached somewhere? In the latter case there may
be an incompatibility problem with the "Shared Tool Options"
proposal (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=90481). For
example, what happens when (a) the "Build Macros" tab of the
"C\C++ build" property page is drawn for the first time, and
(b) what happens if focus switches to another tab and then gets back to
the "Build Macros" tab? The "Shared Tool Options" proposal
would require that the build macro provider is called in both cases as
the values of the macros would have changed between loosing and re-gaining
focus.
[Section 3.6.4]
Q7: Can classes of type IBuildMacroProvider
be defined by the tool integrator? Or are they an internal interface only.
I grepped the document for IBuildMacroProvider and it only appears in this
section or in section 5. Is it intended to be defined from within an MBS
grammar element or through an extension point?
Q8: Further, coming back to my
earlier suggestion (see Q5), you may also want to create function assignMacro(String
macro, String value) which knows how to assign a value to a macro in the
build file.
Q9: The proposal does not make
very clear what happens to macros that are not resolved. These would have
to be defined as "macro = value" in the makefile. Will they be?

Hi All,
I have added that Bugzilla
enhancement request with the Managed Build Macros design attached, see
the Bug 89210:
( https://bugs.eclipse.org/bugs/show_bug.cgi?id=89210
)
The Managed Build Macros support
is one of the MBS enhancements planned to be implemented in the Managed
Build System (MBS) for the CDT 3.0 release (see also "Proposed Managed
Build System functionality for CDT 3.0" ( https://bugs.eclipse.org/bugs/show_bug.cgi?id=81450
))
Thank you
Mikhail
