Yes the bug disappear with execstr ? In fact my example wasn't clear
enough, here is a better one showing my problem. I have a script nammed
bugged.sce
disp('let''s make an error')
ieee(0);1/0 // syntax error
//and I want to test it with and auxiliary script :
unix("rm file.txt")// linux only
diary(0)
try diary('file.txt','new');
exec('bugged.sce',3);
diary('file.txt','close');
catch
disp('added to diary')
[str,n,line,func]=lasterror();
printf(" error %d line %d in %s\n error message :\n
%s\n",n,line,func,str)
end
diary('file.txt','close');
//then I get the expected file.txt
--> disp('let''s make an error')
let's make an error
--> ieee(0);1/0;// syntax error
added to diary
error 999 line 0 in exec
error message :
Division par zéro...
//now replace bugged.sce with
disp('let''s make an error')
1!=0 // syntax error
//then I get a wrong file file.txt
added to diary
error 999 line 4 in
error message :
1!=0;// syntax error
because the diary before the error is lost ! The problem occurs only
with "syntax error" :
'l'apostrophe'
1=2
1!=0
not with old errors like :
ieee(0);1/0
rand(2,2)*rand(3,3);

my goal is to retrieve errors automatically from scripts with bugs (for
example for automatic testing of scripts I didn't wrote myself ) using
lasterror() in the catch statement.

Hello,
As a workaround, if you replace
1!=0 // syntax error
with
str="1!=0";
evstr(str);
it seems to work as you expected.
Anyway, I think the try/catch structure can catch errors occurring at
runtime (like division by zero, etc ...), but not syntax errors.
You are supposed to write syntactically correct Scilab!

Hi,
In scilab-5 I used to save console output of script file execution in a
text file with "diary", this seems to fail in scilab-6, for new errors
types recently added (Syntax error, Unexpected token ). Perhaps I
misunderstood something in try/catch statement , let's consider the file
bug_syntax_error.sce containing :
diary(0)
diary('file.txt','new');
try disp('let''s make an error')
1!=0 // syntax error
catch
disp('added to diary')
end
diary('file.txt','close')
execute this script with CTRL+SHIFT+E or "exec" will not create file.txt

^^
Erreur : Unexpected token '!'
--> mgetl file.txt

execute this script from scinotes with CTRL+E will give :
