Integrating Femtounit with the File Manager and SEdit
I integrated Femtounit, my Interlisp unit test framework, with the File Manager and the SEdit structure editor.
To achieve this I defined the new File Manager type TESTS for Femtounit tests and redefined DEFTEST in terms of it, then tweaked the code formatting of tests in SEdit. Now the system notices and keeps track of new and modified tests.
Here's the File Manager type menu, which SEdit pops up when opening a test, with the DEFTEST option highlighted under TESTS:
Also, now SEdit handles and properly formats test definitions like this of a function SQUARE to compute the square of its argument:
Implementing the new features was much easier than expected.
The traditional way of adding types to the File Manager, described in the Interlisp Reference Manual, involves writing a dozen functions for most of which it's not clear how they're supposed to work. Medley 1.0 added support for two easy to use File Manager type defining forms that replace all that, XCL:DEF-DEFINE-TYPE and XCL:DEFDEFINER. This code is all it took for Femtounit's new TESTS type:
(XCL:DEF-DEFINE-TYPE TESTS "Femtounit unit tests")
(XCL:DEFDEFINER (DEFTEST (:PROTOTYPE
(LAMBDA (NAME)
(AND (LITATOM NAME)
`(DEFTEST ,NAME ("Arg List")
"Body")))))
TESTS
(NAME PARAMETERS &BODY BODY)
`(DEFINEQ (,NAME ,PARAMETERS
(LET ((FTU.TEST.NAME (APPEND FTU.TEST.NAME (LIST ',NAME]
,@BODY))))
This additional tweak makes SEdit format and indent DEFTEST unit test definitions the same way as DEFUN function definitions in Common Lisp:
(SEDIT:DEF-LIST-FORMAT DEFTEST CL:DEFUN)
The simplified process is not discussed in the Interlisp Reference Manual, where I'd have expected, but in a more obscure source, the Medley 1.0 release notes from page 52 of the PDF document. My proactive reading of all the documentation paid off as it let me spot such crucial information and save a lot of work.
