* bug#259: delphi-mode does not properly format interface definitions @ 2008-05-16 16:16 ` Simon South 2008-05-16 16:33 ` bug#260: " Simon South ` (2 more replies) 0 siblings, 3 replies; 10+ messages in thread From: Simon South @ 2008-05-16 16:16 UTC (permalink / raw To: bug-gnu-emacs delphi-mode doesn't properly indent interface definition, things like this: type IHelloWorld = interface(IInvokable) ['{D613A992-AB12-0978-80D1-02B40DF72551}'] function HelloWorld: String; stdcall; end; This is because it doesn't distinguish between the "interface" keyword used as a unit separator (i.e., as opposed to "implementation") and used like a class declaration, as above. As a result, delphi-mode will incorrectly indent the above code this way: type IHelloWorld = interface(IInvokable) ['{D613A992-AB12-0978-80D1-02B40DF72551}'] function HelloWorld: String; stdcall; end; I've taken a stab at updating delphi.el to distinguish between these cases and support "dispinterface" properly as well (patch below) but I don't understand the existing code well enough yet to finish it. (I suspect more changes need to be made to the delphi-enclosing-indent-of function.) Perhaps someone more familiar with this sort of thing could help me complete it?

It doesn't. I've pasted a short program listing below to test with. The patch I submitted will make delphi-mode indent the definition of TestInterface correctly, except that *everything* between the first instance of "interface" and "implementation" is indented one tab space too far to the right. The solution will be to have delphi-mode identify "interface", on its own, as a unit section, and "= interface" as the start of an interface definition. My patch makes the function "delphi-composite-type-start" identify "= interface" as a composite type, so that's part of it done. However, this seems to get overridden in delphi-enclosing-indent-of: As I understand it, as the function parses the line it first identifies "= interface" as a composite type and sets the indentation properly, but then later parses "interface" again on its own and cancels the indentation. (My patch makes the function ignore "interface" the second time so the indentation never gets cancelled, but then that triggers the problem illustrated by the code sample below.) The fix may be as simple as making delphi-enclosing-indent-of interpret "interface" as a unit section only if an equals sign wasn't previously parsed, especially as there already seems to be some logic to do this (see how the "equals-encountered" variable is used). But my LISPmanship is poor and I couldn't get this to work myself.

This adds proper support for the "dispinterface" keyword and for the "interface" keyword when used to define interfaces. I've tested this on the sample unit I posted earlier and on some other files and it works fine. I'll put together a more complete test case and post it here as well if it's useful. The changes are: - Added a "delphi-interface-types" constant to identify the "interface" and "dispinterface" keywords. - Updated the definition of "delphi-composite-types" to include interface types. - Updated the description of "delphi-composite-type-start" to include interface types (and to mention "object", which was previously missing). - Modified the "delphi-enclosing-indent-of" function to recognize the dual meaning of "interface". When that keyword is encountered, the function searches backwards to find the previous non-whitespace token. If that token is an equals sign, "interface" is interpreted as the start of an interface definition; otherwise it's assumed to be the start of a unit section. - Updated the copyright and authorship notices.

As a result, delphi-mode will incorrectly indent the above code this way: type IHelloWorld = interface(IInvokable) ['{D613A992-AB12-0978-80D1-02B40DF72551}'] function HelloWorld: String; stdcall; end; I've taken a stab at updating delphi.el to distinguish between these cases and support "dispinterface" properly as well (patch below) but I don't understand the existing code well enough yet to finish it.
