compile and compile-file now use the CLCS for their diagnostics.
there is even some docs, see
<
http://clisp.podval.org/impnotes/compilation.html#compile-errors>.
it looks decent so far (please do get cvs head and try it yourself):
[6]> (compile-file "../../bugs/c-error")
;; Compiling file /home/sds/src/clisp/bugs/c-error.lisp ...
** - Continuable Error
in F in line 1 : Code contains dotted list (BLOCK F . X)
If you continue (by typing 'continue'): Ignore the error and proceed
The following restarts are also available:
ABORT :R1 Abort main loop
Break 1 [7]> :c
WARNING: in F in line 1 : variable X is not used.
Misspelled or missing IGNORE declaration?
** - Continuable Error
in C in lines 3..7 : CASE: the T clause must be the last one:
(CASE X (1 2) (T 4) (5 6))
If you continue (by typing 'continue'): Ignore the error and proceed
The following restarts are also available:
ABORT :R1 Abort main loop
Break 1 [8]> :c
** - Continuable Error
in H in lines 9..11 : Illegal syntax in LET/LET*: (A A A)
If you continue (by typing 'continue'): Ignore the error and proceed
The following restarts are also available:
ABORT :R1 Abort main loop
Break 1 [9]> :c
;; Deleted file /home/sds/src/clisp/bugs/c-error.fas
There were errors in the following functions:
F C H
3 errors, 1 warning
NIL ;
4 ;
3
[10]>
so you can examine errors are they are signaled.
except for one unpleasant glitch:
compile errors are signaled as continuable errors (so that on can
"ignore and proceed" to deal with the problem later) of type
source-program-error (so that some error context is available
programmatically), but this means that "clisp -c" which uses
appease-cerrors, will report errors as warnings:
$ ./clisp -q -norc -c ../../bugs/c-error.lisp
STACK size: 98206 [0xb7cfcf00 0xb7c9d088]
;; Compiling file /home/sds/src/clisp/bugs/c-error.lisp ...
WARNING: in F in line 1 : Code contains dotted list (BLOCK F . X)
Ignore the error and proceed
WARNING: in F in line 1 : variable X is not used.
Misspelled or missing IGNORE declaration?
WARNING: in C in lines 3..7 : CASE: the T clause must be the last one:
(CASE X (1 2) (T 4) (5 6))
Ignore the error and proceed
WARNING: in H in lines 9..11 : Illegal syntax in LET/LET*: (A A A)
Ignore the error and proceed
;; Deleted file /home/sds/src/clisp/bugs/c-error.fas
There were errors in the following functions:
F C H
3 errors, 1 warning
what do I do about this?
-- nothing: the "Ignore the error and proceed" is a sufficient indicator
that this is actually an error
-- replace appease-cerrors with something compile-file-specific, which
will print a more explicit message
-- remove appease-cerrors and just fail the whole file on the first error.
opinions?
patches?
