Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi,
See example below of wrong quotes and of a site to check their encoding:
// http://asciivalue.com/
// Wrong quotes:
// Char Dec Hex Oct
// " 148 94 224
// Right quotes:
// Char Dec Hex Oct
// " 34 22 42
// Scilab code:
printf("Wrong quotes: "\n")
printf("Right quotes: '"\n")
SciNotes Find/Replace can be used to replace all.

Rafael

Hi Samuel
I wonder in which way I as a user is supposed to find a wrongly encoded
quote. I again copied the original code to an editor and studied the HEX
code. All (single-) quotes have HEX code 27.
When I save the .sce file to disk, the information in the file contains
nothing outside the ordinary. Yet, when I reopened this file in Scilab 6
(many times) then each time, the problem would be the same. Scilab 5 has
no problems. To me it doesn't sound like a problem with the TEXT file,
but a problem inside Scilab 6 editor + parser.

I think you're right. The clear statement (without specific reference to
anything) seems to clear a bit too much, so I've removed it from the
initialization part of my script. Not only does it clear too much, but I
have to reboot the computer to get it to behave ... at least, this
solved my problem once. As with my other messages tonight, things seems
to be "messy" and I'm not comfortable speaking in general terms until I
have re-tested this over some period of time.
P.S. Sorry for the _many_ emails today ...

Hi there
I've started to use the prettify functions by Pierre Vuillemin. So

If I start Scilab, first time I execute the code, I get an "Invalid

Second time I execute the code then I get a bad message:

from previous run that is the problem. Or ???
The "line 93" is part of the default options in Prettify, where it
says labels_font_size. It looks like this:
default_options = struct('title_font_size', 4,...

Can anyone spot, what is the problem?
P.S. This part of the code is in a section that is controlled by an
if-statement, and even if I make sure the condition is false (so
that the Prettify code is not executed), Scilab still spits out
this error. It's really weird - and even weirder it doesn't get the
error the first time that the code is executed.

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi Samuel, et al. (I write this response just for completeness)
I loaded the Prettify code that generated an error (the default_options
code) into my Programming Editor, which has a HEX editor function. I
walked through all chars in the code to see if there was any peculiar
ASCii code. There was not. The lowest ASCii char in the code was 20
(i.e. a space) and the highest was 7A (i.e. a z). This means every byte
in the code is (and has always been) within the normal ASCii chars.
P.S. The editor I use is TSE (The Semware Editor) Pro 4.20, see
https://www.semware.com/ for details.

Weird errors sometimes occur after copying/pasting some code from a
rich text formated document to Scinotes or the console. Some usual
characters like the space or quotes may have some special encoding
in formated text, and keep it in Scinotes, but are not aknowledged
by the parser.
The last time i got this situation, it was about spaces that looked
like spaces, but that were not ascii(32). To avoid this, i pasted
the text in a raw text unformated .txt file before copying/pasting
in Scinotes.
If you have copied/pasted some code directly from the web (like
Pierre's Github page), it could be a source of encoding bugs: Web
pages often use unbreakable spaces ( in HTML). I am pretty sure
that Scilab's parser doesn't like them.

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi Pierre, et al.
I was able to resolve the problem with the Prettify code by changing '
to " in the code for default_options.
I have no idea why this should matter. AFAIR Scilab accepts both (just
not mixed anymore - and there's no mix-up in the code). Just to prevent
confusion, here's the code change which works for me (at the moment,
again, we'll see tomorrow if the fix continues to work):
default_options = struct("title_font_size", 4,...
"labels_font_size" , 3,...
"thicks_font_size" , 2,...
"num_format" , '',...
"leg_font_size" , 3,...
"line_thickness" , 2,...
"xstring_font_size" , 2);
// default_options = struct('title_font_size', 4,...
// 'labels_font_size', 3,...
// 'thicks_font_size', 2,...
// 'num_format', '',...
// 'leg_font_size', 3,...
// 'line_thickness', 2,...
// 'xstring_font_size', 2)

Hi Claus,
You need to spot where the 'invalid buffer' message comes from. Adding
'pause' statements throughout your script may help you (or is there a
debugging step by step tool? I don't know). Or you may want to comment
suspicious parts of your code until there is no more error
Do you read data at some point? I would intuitively suspect such a
message to be related to some data input/data reading operation but I
may be mistaken.
Besides, I've encountered a similar behaviour where Scilab 6 seems to
work during the first run of a script but then something goes wrong
and nothing works quite right anymore (like error messages out of the
place) until Scilab is restarted. At this point I find this version
quite unstable.

The "Invalid buffer." message becomes even weirder. It is not in the

I guarantee it's not an error message I've made up myself. The entire

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi Samuel
>I do not really understand how you could use prettify() if it is not
in a protected autoloaded ATOMS library
For potential easy distribution of the code, I do not include any
requirement of any ATOMS modules, just clean Scilab installation is
expected and everything is contained in a single .sce file.
Since Prettify code was released as source code in a way, I have copied
the entire text into my mainline-script. Hence the functions are loaded
each time I run the code. The code includes the authorship / code
ownership of Pierre Vuillemin and mentions the BSD license that comes
with it. It's in my mainline script from line 47 to line 231.
To the best of my knowledge Prettify is currently not available as an
ATOMS module. Am I right?

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi Samuel
OK, I see - regarding clear.
Yes, maybe the new debugger could be helpful.
The code is not top-secret, but to test the complete code in a
meaningful way I'd need to also include 40 kb of data... so it's best to
share with private email to whom wish to help me out.
P.S. The tip with copy-paste from "rich" source could indeed be the
problem. I don't know (and don't remember) ... but it works fine in
Scilab 5.5.

variables, all graphics and clears console, so it's not "old" stuff

The "line 93" is part of the default options in Prettify, where it
says labels_font_size. It looks like this:
default_options = struct('title_font_size', 4,...
'labels_font_size' , 3,...

P.S. This part of the code is in a section that is controlled by an
if-statement, and even if I make sure the condition is false (so
that the Prettify code is not executed), Scilab still spits out
this error. It's really weird - and even weirder it doesn't get the
error the first time that the code is executed.
P.S. My entire code is ca. 915 lines long + requires input data, so
I prefer not to attach it to a post here in the mailing list.

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi Pierre
>At this point I find this version quite unstable.
Yes. If I don't find a solution, I'll have to revert to Scilab 5.5 ...
but 6.0 is so much faster with graphics, so I'll continue a bit to see
what's the problem.

Hi Claus,
You need to spot where the 'invalid buffer' message comes from. Adding
'pause' statements throughout your script may help you (or is there a
debugging step by step tool? I don't know). Or you may want to comment
suspicious parts of your code until there is no more error
Do you read data at some point? I would intuitively suspect such a
message to be related to some data input/data reading operation but I
may be mistaken.
Besides, I've encountered a similar behaviour where Scilab 6 seems to
work during the first run of a script but then something goes wrong
and nothing works quite right anymore (like error messages out of the
place) until Scilab is restarted. At this point I find this version
quite unstable.

I guarantee it's not an error message I've made up myself. The entire

characters like the space or quotes may have some special encoding in
formated text, and keep it in Scinotes, but are not aknowledged by the
parser.
The last time i got this situation, it was about spaces that looked
like spaces, but that were not ascii(32). To avoid this, i pasted the
text in a raw text unformated .txt file before copying/pasting in
Scinotes.
If you have copied/pasted some code directly from the web (like Pierre's
Github page), it could be a source of encoding bugs: Web pages often use
unbreakable spaces ( in HTML). I am pretty sure that Scilab's
parser doesn't like them.

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi Samuel
About "clear" I looked and it's still a documented feature in 6.0:
https://help.scilab.org/docs/6.0.0/en_US/clear.html
I also revisited the 6.0 Release Notes (PDF) and it lists only these as
obsolete:
Obsolete functions or features w maxfiles is now obsolete.
w isoview(xmin,xmax,ymin,ymax) is deprecated. Please use isoview("on"),
replot(..) instead.
w eval3d will be removed from Scilab 6.1. Please use ndgrid instead.
w strcmpi is deprecated. Please use strcmp(..,"i")instead.
w square will be removed from Scilab 6.1. Please use gcf().axes_ size
and replot instead.
... You might be right that clear is on its way out, but I don't know
where to find the information.

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Hi Samuel, et al.
Thanks for the tip, I commented "// clear;" - so this is no longer executed.
First script run still generate the "Invalid buffer." error - and second
run still generate the line 93 error.
This level of debugging is not my strong side. Sorry.
This is really weird. I modified my script so that the first line
executed is "disp("hello1");" ... I never see this message displayed,
only the below error. The only thing that "works" is to close down and
restart Scilab.
P.S. I believe I looked through the changes to 6.0 to ensure that I
wasn't using any functions that cannot work under 6.0, but I might have
failed. Is there a tool which can parse a script and give advice?
Best regards,
Claus

Re: [Scilab-users] Scilab 6 problem with "Prettify"
Dear Claus,
I've not experienced any issue on Scilab 6 so far with this routine.
If this error shows up even if the code is not executed then the error
may come from elsewhere? I've had some issues with Scilab 6 error
messages pointing out the wrong chunk of code.
The "invalid buffer" message may indicate that there is a problem during
the first run. I would start by investigating this part.
Best regards,
Pierre

much faster), but I get a weird error.
If I start Scilab, first time I execute the code, I get an "Invalid
buffer." message.
Second time I execute the code then I get a bad message:
--> exec('C:\Users\claus\Documents\Scilab54\z3mfit.sce', -1)
at line 93 of executed file C:\Users\claus\Documents\Scilab54\z3mfit.sce
'labels_font_size' , 3,...
^^
Error: syntax error, unexpected "'", expecting "," or )
When I run my script, the first thing my code does - it clears all
variables, all graphics and clears console, so it's not "old" stuff from
previous run that is the problem. Or ???
The "line 93" is part of the default options in Prettify, where it says
labels_font_size. It looks like this:
default_options = struct('title_font_size', 4,...
'labels_font_size' , 3,...
'thicks_font_size' , 2,...
'num_format' , '',...
'leg_font_size' , 3,...
'line_thickness' , 2,...
'xstring_font_size' , 2)
Can anyone spot, what is the problem?
P.S. This part of the code is in a section that is controlled by an
if-statement, and even if I make sure the condition is false (so that
the Prettify code is not executed), Scilab still spits out this error.
It's really weird - and even weirder it doesn't get the error the first
time that the code is executed.
P.S. My entire code is ca. 915 lines long + requires input data, so I
prefer not to attach it to a post here in the mailing list.
Best regards,
Claus
