Carlos 29-Jun-2005 [821] | while I am posting this I notice the foreign characters under Linux is not yet solved. Using Debian Ubuntu with brazilian ABNT2 keyboard layout I am not able to input some usual characters in Portuguese such as Ža Že Ži Žo `u `a ^o ~a . |
Izkata 29-Jun-2005 [822x2] | Not sure if it goes here.. but Rebol 1.3 doesn't seem to like the bit on a Draw animation in the cookbook: http://www.rebol.net/cookbook/recipes/0047.html (specifically, the adding and subtracting in the draw block...) |
Nevermind, I haven't been paying much attention to the Draw dialect evolution - but the Cookbook ought to still be updated, right? | |
Anton 30-Jun-2005 [824x2] | Is the Rambo CGI code public ? |
Izkata, right, submitted a rambo ticket with fixed code for that cookbook entry. | |
Gregg 30-Jun-2005 [826] | RAMBO code is not public at this time. |
Maarten 30-Jun-2005 [827] | ANton: if you ask Carl you may get lucky. |
Anton 30-Jun-2005 [828] | Oh, I just wanted to make a suggestion for the green "RAMBO Statistics" box. I would like each number to be a link that is the rambo search query which gives the tickets in question. ie. "New tickets: 1" - when you click on the "1", you should get a page with the summary of the new ticket. But before I did that, I wanted to see if I could help by writing the code to implement the change. |
Ladislav 1-Jul-2005 [829x6] | this looks strange: >> o: make object! [test-word: none] >> do bind probe reduce [to set-path! 'test-word to lit-word! 'test-contents] in o 'self [test-word: 'test-contents] == test-contents >> probe o make object! [ test-word: none ] |
it looks like needing Rambo presence, doesn't it? | |
simplified: >> do probe reduce [to set-path! 'tst-word 1] [tst-word: 1] ** Script Error: tst-word has no value ** Near: tst-word: 1 | |
ah, sorry, it is 1.2.48 | |
this is 1.3 result: >> probe reduce [to set-path! 'tst-word 1] [tst-word: 1] == [tst-word: 1] >> tst-word ** Script Error: tst-word has no value ** Near: tst-word | |
ah, I missed do when pasting, the results of 1.2.48 and 1.3. are the same, sorry for any confusion | |
Romano 1-Jul-2005 [835] | Lad what is exactly the problem for you? |
Ladislav 1-Jul-2005 [836x2] | it is strange, that a set-path behaves this way |
do probe reduce [to set-path! 'tst-word 1] should set tst-word without protests | |
Romano 1-Jul-2005 [838] | set-path! should fire an error in this case, right? |
Ladislav 1-Jul-2005 [839] | no |
Romano 1-Jul-2005 [840] | should behave like a set-word!? |
Ladislav 1-Jul-2005 [841] | why not? |
Romano 1-Jul-2005 [842x2] | i think that a path! with only 1 slot is a bad formed path |
can be useful for insert/remove, but not for evaluate | |
Ladislav 1-Jul-2005 [844x3] | it already behaves like a set-word in case its length is higher than one, that is why I think, that the behaviour is natural |
I needed to handle this: foreach [path value] [a 1 o/b 2] [do reduce [to set-path! path value]] | |
and was very surprised, that it didn't work | |
Romano 1-Jul-2005 [847] | The problem i think is the first slot has a different meaning from second, third and so on |
Ladislav 1-Jul-2005 [848] | nevertheless, the behaviour is wrong and unnatural, I vote for the least surprising behaviour in this case |
Romano 1-Jul-2005 [849x2] | It is a surprise for me that a set-path! == set-word! |
but it can be useful | |
Ladislav 1-Jul-2005 [851] | even an error may be more natural than the observed behaviour, but if the operation is valid, then there is no other choice |
Romano 1-Jul-2005 [852] | that 'a in your example is a global word? |
Ladislav 1-Jul-2005 [853x3] | in my example yes, but I had a more complicated code originally |
where it wasn't a global word | |
I wanted to manipulate an object or its subobjects using this notation and had to find and circumvent this bug | |
Romano 1-Jul-2005 [856] | i agree on one fact! it should at least rise the bad-path error! |
Ladislav 1-Jul-2005 [857x2] | OTOH, it seems logical to allow expression: to set-path 'a-word |
and if such an expression isn't illegal, then there is not much choice left | |
Romano 1-Jul-2005 [859x2] | I think that give too importance to the fact that a set-path with 1 slot is molded like a set-word (anc cannot be loaded as a set-path). But the first word of a set-path is not the same of a word! of a set-word!: the set-path word must be get and then selected. |
The set-word word is like a second word in a path, the first hidden, implicit word! in a set-word is the context bound to the word. | |
Ladislav 1-Jul-2005 [861] | funny and "stupid" example: do reduce [sp: to set-path! [] 1] |
Romano 1-Jul-2005 [862] | but i agree: your proposal can be useful, it is like to have to-set-word which does not change the context of a word |
Ladislav 1-Jul-2005 [863] | OTOH you are right, that it *may* slow down set-path handling (?) |
Romano 1-Jul-2005 [864x2] | i do not think too much, but it is true it needs a separate test and handling |
also because the action "set the value" is not done by the set-path datatype! it is like an action sent to the datatype of the value 1 slot before the end of the path | |
Ladislav 1-Jul-2005 [866] | another experiment: >> a: func [/b] [print b] >> a/b: "OK" true == "OK" >> get second second :a == true |
Izkata 2-Jul-2005 [867x2] | yarg... 'try was changed.. I just spent a half hour trying to figure out why a -short- peice of code would work! >> try [to-time {Hi}] == none >> ? try USAGE: TRY block DESCRIPTION: Tries to DO a block and returns its value or an error. ;What happend to the error? TRY is a native value. |
would->wouldn't* | |
Allen 2-Jul-2005 [869x2] | It has nothing to do with TRY at all. |
to-time {hi} is returning none. so therefore there is no error for TRY to trap | |
