Even more long line breaking.
guard agains source path mapping hitting reader errors Example: compile (defun foo () (bar)) in a file. Edit the definition to look like (defun foo () (nopackage:bar)), close the file and hit M-. foo. Prior to this an error shows in the minibuffer, and nothing else happens.
* swank-source-path-parser.lisp (make-source-recorder) (source-path-source-position): Adjust the file-position before entering it the table.
* swank-source-path-parser.lisp The source parser READs in files, and if such a file contains some nasty #. hackery that results in an error being signalled, M-. would fail on anything that's defined in those files. Fix that by using a special #. reader function that invokes the original #. reader with an IGNORE-ERRORS wrapped around. (make-sharpdot-reader): New function. (make-source-recording-readtable): Use it and install it on #. * slime.el (find-definition.2): New test case to guard against it.
* swank-source-path-parser.lisp: Multibyte characters in files could screw up compiler-notes highlighting on SBCL. Fix that. (skip-toplevel-forms): Abstracted out from READ-SOURCE-FORM. (source-path-file-position): Don't operate on the file stream directly, since CL:FILE-POSITION may not return character but binary offsets on such streams; instead slurp file content into a buffer string, and operate on that.
Fix source-path mapping for #+#.'(:and). Patch by Luis Oliveira. * swank-source-path-parser.lisp (make-source-recording-readtable): don't suppress the #. reader macro. (read-and-record-source-map): don't bind *read-eval* to nil. (suppress-sharp-dot): unused, delete it. * slime.el (test compile-defun): test with #+#.'(:and).
(suppress-sharp-dot): Return a unique symbol to avoid nil entries at toplevel in the source-map.
(make-source-recording-readtable): Suppress the #. reader-macro. (suppress-sharp-dot): New function. (read-source-form): Disable *read-eval*. (*source-map*): Deleted. We can do everything with a lexical variable.
Added public domain dedication.
(read-and-record-source-map): Ensure that at least the toplevel form is in the source-map.
(check-source-path): Signal an error if a source path is malformed. SBCL sometimes gives (NIL). (source-path-stream-position): Use it.
(make-source-recording-readtable): Ignore non-ascii chars.
(read-source-form): New function. Common code from source-path-stream-position and form-number-stream-position. (source-path-stream-position): Use it.
(source-path-stream-position): Bind *read-suppress* to nil before calling read-and-record-source-map.
(source-path-stream-position): Bind *read-suppress* only as long as we skip over forms. The last toplevel form in the path is read with *read-suppress* = nil because in newer versions of CMUCL and SBCL read will return nil if *read-suppress* is t.
Remove workarounds for SBCL bugs. The bugs are fixed in the versions we support.
Removed caching of readtables and the source-map hashtable. Fresh creation is ultra-cheap (<1ms). The caching didn't handle modifications to readtables and generally made me feel uneasy while tracking down an obscure bug in a reader macro. The cached source-map hashtable also wasn't thread-safe (ho hum).
(cmucl-style-get-macro-character): Add tests for #\space and #\\. (Suggested by Christophe Rhodes.)
(cmucl-style-get-macro-character): The feature is CMU not CMUCL.
(cmucl-style-get-macro-character): New function. Workaround for bug(?) in SBCL. (make-source-recording-readtable): Use it.
We are in-package :swank-backend. Thanks to Raymond Wiker.
Implement changed backend interface and remove references to front end symbols.
Patch by Robert E. Brown. Add type declarations to keep SBCL quiet.
