gcc3 issues... 23 years, 3 months

Valdis Kl=?iso8859-4?Q?=BA?=tnieks

gcc3 won't compile the current CVS with -fomit-frame-pointer. The gcc3-3.0-5 RPM from RedHat fails while trying to start ./temacs with a bad branch into Flax_plist_get(). gcc-2.96-94 RPM works fine. ./configure --dynamic=yes --debug=no --error-checking=none --with-mule=yes \ --compiler=gcc3 '--cflags=-Wall -Winline -Wmissing-prototypes -Wmissing-declarations -Wno-switch -Wpointer-arith -Wno-sign-compare -Wno-uninitialized -Wshadow -O3 -fno-exceptions -fno-rtti -ffast-math -fexpensive-optimizations -pipe -s -mcpu=i686 -march=i686' works, but adding -fomit-frame-pointer causes problems. I haven't figured out yet whether this is a GCC 3.0 bug, or if XEmacs is doing something that's technically illegal that 2.96 let slide that 3.0 screws up on if using -fomit-frame-pointer. /Valdis

While it is ;; possible to assign actions in the bovine-table in a similar fashion ;; to bison, this is not it's end goal. -;; -;; Bovine Table Tips & Tricks: -;; --------------------------- -;; -;; Many of the tricks needed to create rules in bison or yacc can be -;; used here. The exceptions to this rule are that there is no need to -;; declare bison tokens, and you cannot put "code" in the middle of a -;; match rule. In addition, you should avoid empty matching rules as -;; I haven't quite gotten those to be reliable yet. -;; -;; The top-level bovine table is an association list of all the rules -;; needed to parse your language, or language segment. It is easiest -;; to create one master rule file, and call the semantic bovinator on -;; subsections passing down the nonterminal rule you want to match. -;; -;; Thus, every entry in the bovine table is of the form: -;; ( NONTERMINAL-SYMBOL MATCH-LIST ) -;; -;; The nonterminal symbol is equivalent to the bison RESULT, and the -;; MATCH-LIST is equivalent to the bison COMPONENTS. Thus, the bison -;; rule: -;; expseq: expseq1 -;; | expseq2 -;; ; -;; becomes: -;; ( expseq ( expseq1 ) ( expseq2 ) ) -;; which defines RESULT expseq which can be either COMPONENT expseq1 -;; or expseq2. These two table entries also use nonterminal results, -;; and also use the DEFAULT RESULT LAMBDA (see below for details on -;; the RESULT LAMBDA). -;; -;; You can also have recursive rules, as in bison. For example the -;; bison rule: -;; expseq1: exp -;; | expseq1 ',' exp -;; ; -;; becomes: -;; (expseq1 (exp) -;; (expseq1 punctuation "," exp -;; (lambda (val start end) -;; ( -generator code- )))) -;; -;; This time, the second rule uses it's own RESULT LAMBDA. -;; -;; Lastly, you can also have STRING LITERALS in your rules, though -;; these are different from Bison. As can be seen above, a literal is -;; a constant lexed symbol, such as `punctuation', followed by a string -;; which is a *regular expression* which must match, or this rule will -;; fail. -;; -;; In BISON, a given rule can have inline ACTIONS. In the semantic -;; bovinator, there can be only one ACTION which I will refer to here -;; as the RESULT LAMBDA. There are two default RESULT LAMBDAs which -;; can be used which cover the default case. The RESULT LAMBDA must -;; return a valid nonterminal token. A nonterminal token is always of the -;; form ( NAME TOKEN VALUE1 VALUE2 ... START END). NAME is the name -;; to use for this token. It is first so that a list of tokens is -;; also an alist, or completion table. Token should be the same -;; symbol as the nonterminal token generated, though it does not have to -;; be. The values can be anything you want, including other tokens. -;; START and END indicate where in the buffer this token is, and is -;; easily derived from the START and END parameter passed down. -;; -;; A RESULT LAMBDA must take three parameters, VALS, START and END. -;; VALS is the list of literals derived during the bovination of the -;; match list, including punctuation, parens, and explicit -;; matches. other elements -;; -;; Here are some example match lists and their code: -;; -;; (expression (lambda (vals start end) -;; (append (car vals) (list start end)))) -;; -;; In this RESULT LAMBDA, VALS will be of length one, and it's first -;; element will contain the nonterminal expression result. It is -;; likely to use a rule like this when there is a top level nonterminal -;; symbol whose contents are several other single nonterminal rules. -;; Because of this, we want to result that value with our START and END -;; appended. -;; -;; NOTE: nonterminal values passed in as VALS always have their -;; START/END parts stripped! -;; -;; This example lambda is also one of the DEFAULT lambdas for the case -;; of a single nonterminal result. Thus, the above rule could also be -;; written as (expression). -;; -;; A more complex example uses more flex elements. Lets match this: -;; -;; (defun myfunction (arguments) "docstring" ...) -;; -;; If we assume a flex depth of 1, we can write it this way: -;; -;; (open-paren "(" symbol "defun" symbol semantic-list string -;; (lambda (vals start end) -;; (list (nth 2 vals) 'function nil (nth 3 vals) -;; (nth 4 vals) start end))) -;; -;; The above will create a function token, whose format is -;; predefined. (See the symbol `semantic-toplevel-bovine-table' for -;; details on some default symbols that should be provided.) -;; -;; From this we can see that VALS will have the value: -;; ( "(" "defun" "myfunction" "(arguments)" "docstring") -;; -;; If we also want to return a list of arguments in our function -;; token, we can replace `semantic-list' with the following recursive -;; nonterminal rule. -;; -;; ( arg-list (semantic-list -;; (lambda (vals start end) -;; (semantic-bovinate-from-nonterminal start end 'argsyms)))) -;; ( argsyms -;; (open-paren argsyms (lambda (vals start end) -;; (append (car (cdr vals)) (list start end)))) -;; (symbol argsyms (lambda (vals start end) -;; (append (cons (car vals) (car (cdr vals))) -;; (list start end)))) -;; (symbol close-paren (lambda (vals start end) -;; (list (car vals) start end)))) -;; -;; This recursive rule can find a parenthetic list with any number of -;; symbols in it. -;; -;; Here we also see a new function, `semantic-bovinate-from-nonterminal'. -;; This function takes START END and a nonterminal result symbol to -;; match. This will return a complete token, including START and -;; END. This function should ONLY BE USED IN A RESULT LAMBDA. It -;; uses knowledge of that scope to reduce the number of parameters -;; that need to be passed in. This is useful for decomposing complex -;; syntactic elements, such as semantic-list. -;; -;; Token's and the VALS argument -;; ----------------------------- -;; -;; Not all syntactic tokens are represented by strings in the VALS argument -;; to the match-list lambda expression. Some are a dotted pair (START . END). -;; The following are represented as strings: -;; 1) symbols -;; 2) punctuation -;; 3) open/close-paren -;; 4) charquote -;; 5) strings -;; The following are represented as a dotted-pair. -;; 1) semantic-list -;; 2) comments -;; Nonterminals are always lists which are generated in the lambda -;; expression. -;; -;; Semantic Bovine Table Debugger -;; ------------------------------ -;; -;; The bovinator also includes a primitive debugger. This debugger -;; walks through the parsing process and see how it's being -;; interpretted. There are two steps in debuggin a bovine table. -;; -;; First, place the cursor in the source code where the table is -;; defined. Execute the command `semantic-bovinate-debug-set-table'. -;; This tells the debugger where you table is. -;; -;; Next, place the cursor in a buffer you which to run the bovinator -;; on, and execute the command `semantic-bovinate-buffer-debug'. This -;; will parse the table, and highlight the relevant areas and walk -;; through the match list with the cursor, displaying the current list -;; of values (which is always backwards.) -;; -;; DESIGN ISSUES: -;; ------------- -;; -;; At the moment, the only thing I really dislike is the RESULT -;; LAMBDA format. While having some good defaults is nice, the use -;; of append and list in the lambda seems unnecessarily complex. -;; -;; Also of issue, I am still not sure I like the idea of stripping -;; BEGIN/END off of nonterminal tokens passed down in VALS. While they -;; are often unnecessary, I can imagine that they could prove useful. -;; Only time will tell. ;;; History: ;; (require 'working) -(require 'semantic-util) (defgroup semantic nil - "File and tag browser frame." + "Parser Generator/Parser." ) ;;; Code: ＠＠ -243,6 +67,14 ＠＠ (defalias 'semantic-overlay-lists (lambda () (list (extent-list)))) (defalias 'semantic-overlay-p 'extentp) + (defun semantic-read-event () + (let ((event (next-command-event))) + (if (key-press-event-p event) + (let ((c (event-to-character event))) + (if (char-equal c (quit-char)) + (keyboard-quit) + c))) + event)) ) (defalias 'semantic-overlay-live-p 'overlay-buffer) (defalias 'semantic-make-overlay 'make-overlay) ＠＠ -258,6 +90,7 ＠＠ (defalias 'semantic-overlay-previous-change 'previous-overlay-change) (defalias 'semantic-overlay-lists 'overlay-lists) (defalias 'semantic-overlay-p 'overlayp) + (defalias 'semantic-read-event 'read-event) ) (defvar semantic-edebug nil ＠＠ -317,7 +150,7 ＠＠ Bovine table entry return elements are up to the table author.

While it is ;; possible to assign actions in the bovine-table in a similar fashion ;; to bison, this is not it's end goal. -;; -;; Bovine Table Tips & Tricks: -;; --------------------------- -;; -;; Many of the tricks needed to create rules in bison or yacc can be -;; used here. The exceptions to this rule are that there is no need to -;; declare bison tokens, and you cannot put "code" in the middle of a -;; match rule. In addition, you should avoid empty matching rules as -;; I haven't quite gotten those to be reliable yet. -;; -;; The top-level bovine table is an association list of all the rules -;; needed to parse your language, or language segment. It is easiest -;; to create one master rule file, and call the semantic bovinator on -;; subsections passing down the nonterminal rule you want to match. -;; -;; Thus, every entry in the bovine table is of the form: -;; ( NONTERMINAL-SYMBOL MATCH-LIST ) -;; -;; The nonterminal symbol is equivalent to the bison RESULT, and the -;; MATCH-LIST is equivalent to the bison COMPONENTS. Thus, the bison -;; rule: -;; expseq: expseq1 -;; | expseq2 -;; ; -;; becomes: -;; ( expseq ( expseq1 ) ( expseq2 ) ) -;; which defines RESULT expseq which can be either COMPONENT expseq1 -;; or expseq2. These two table entries also use nonterminal results, -;; and also use the DEFAULT RESULT LAMBDA (see below for details on -;; the RESULT LAMBDA). -;; -;; You can also have recursive rules, as in bison. For example the -;; bison rule: -;; expseq1: exp -;; | expseq1 ',' exp -;; ; -;; becomes: -;; (expseq1 (exp) -;; (expseq1 punctuation "," exp -;; (lambda (val start end) -;; ( -generator code- )))) -;; -;; This time, the second rule uses it's own RESULT LAMBDA. -;; -;; Lastly, you can also have STRING LITERALS in your rules, though -;; these are different from Bison. As can be seen above, a literal is -;; a constant lexed symbol, such as `punctuation', followed by a string -;; which is a *regular expression* which must match, or this rule will -;; fail. -;; -;; In BISON, a given rule can have inline ACTIONS. In the semantic -;; bovinator, there can be only one ACTION which I will refer to here -;; as the RESULT LAMBDA. There are two default RESULT LAMBDAs which -;; can be used which cover the default case. The RESULT LAMBDA must -;; return a valid nonterminal token. A nonterminal token is always of the -;; form ( NAME TOKEN VALUE1 VALUE2 ... START END). NAME is the name -;; to use for this token. It is first so that a list of tokens is -;; also an alist, or completion table. Token should be the same -;; symbol as the nonterminal token generated, though it does not have to -;; be. The values can be anything you want, including other tokens. -;; START and END indicate where in the buffer this token is, and is -;; easily derived from the START and END parameter passed down. -;; -;; A RESULT LAMBDA must take three parameters, VALS, START and END. -;; VALS is the list of literals derived during the bovination of the -;; match list, including punctuation, parens, and explicit -;; matches. other elements -;; -;; Here are some example match lists and their code: -;; -;; (expression (lambda (vals start end) -;; (append (car vals) (list start end)))) -;; -;; In this RESULT LAMBDA, VALS will be of length one, and it's first -;; element will contain the nonterminal expression result. It is -;; likely to use a rule like this when there is a top level nonterminal -;; symbol whose contents are several other single nonterminal rules. -;; Because of this, we want to result that value with our START and END -;; appended. -;; -;; NOTE: nonterminal values passed in as VALS always have their -;; START/END parts stripped! -;; -;; This example lambda is also one of the DEFAULT lambdas for the case -;; of a single nonterminal result.

This debugger -;; walks through the parsing process and see how it's being -;; interpretted. There are two steps in debuggin a bovine table. -;; -;; First, place the cursor in the source code where the table is -;; defined. Execute the command `semantic-bovinate-debug-set-table'. -;; This tells the debugger where you table is. -;; -;; Next, place the cursor in a buffer you which to run the bovinator -;; on, and execute the command `semantic-bovinate-buffer-debug'. This -;; will parse the table, and highlight the relevant areas and walk -;; through the match list with the cursor, displaying the current list -;; of values (which is always backwards.) -;; -;; DESIGN ISSUES: -;; ------------- -;; -;; At the moment, the only thing I really dislike is the RESULT -;; LAMBDA format. While having some good defaults is nice, the use -;; of append and list in the lambda seems unnecessarily complex. -;; -;; Also of issue, I am still not sure I like the idea of stripping -;; BEGIN/END off of nonterminal tokens passed down in VALS. While they -;; are often unnecessary, I can imagine that they could prove useful. -;; Only time will tell. ;;; History: ;; (require 'working) -(require 'semantic-util) (defgroup semantic nil - "File and tag browser frame." + "Parser Generator/Parser." ) ;;; Code: ＠＠ -243,6 +67,14 ＠＠ (defalias 'semantic-overlay-lists (lambda () (list (extent-list)))) (defalias 'semantic-overlay-p 'extentp) + (defun semantic-read-event () + (let ((event (next-command-event))) + (if (key-press-event-p event) + (let ((c (event-to-character event))) + (if (char-equal c (quit-char)) + (keyboard-quit) + c))) + event)) ) (defalias 'semantic-overlay-live-p 'overlay-buffer) (defalias 'semantic-make-overlay 'make-overlay) ＠＠ -258,6 +90,7 ＠＠ (defalias 'semantic-overlay-previous-change 'previous-overlay-change) (defalias 'semantic-overlay-lists 'overlay-lists) (defalias 'semantic-overlay-p 'overlayp) + (defalias 'semantic-read-event 'read-event) ) (defvar semantic-edebug nil ＠＠ -317,7 +150,7 ＠＠ Bovine table entry return elements are up to the table author.

'(initial-frame-plist (quote (minibuffer t top 5 left 300 height 40 width 80)))) is supposed to set the initial frame geometry in one sweep. This, however, does not happen on startup UNTIL I either click on the XEmacs frame or start typing at it. This is a long-standing bug, at least on Windows. Dan> When I change the frame position line to: Dan> (set-frame-position (buffer-dedicated-frame) 100 100) Dan> Then the window moves to '100 100' instead of '0 0'. Dan> Have you tried the above commands? Yep. Dan> Do they work for you? Yep. Dan> -- Dan> Dan Espen -- Adrian Aichner mailto:adrian＠xemacs.org http://www.xemacs.org/

freshmeat project listing for XEmacs 23 years, 3 months

jeff covey

I'm writing in reference to your project "XEmacs". Since the time you submitted this project to us, freshmeat has adopted a new categorization system which allows much more fine-grained organization of projects. Since your project has never been recategorized under this system, our readers aren't finding your project when they browse through categories where it should be listed. We'd like to ask you to take just a few minutes to recategorize your project. You should delete any categories which begin with "Old Appindex" and add all of the new categories which apply to your project. You can edit your project listing at: http://freshmeat.net/projects/xemacs/ with the "recategorize" function in the menu. While you're there, take a moment to make sure everything else is up-to-date. If you have any problems, please let us know at http://freshmeat.net/contact/. Thanks for listing your project in our database. Sincerely, Jeff Covey
