Hello,
I have just discovered that, since Scilab 6.0.0, at least for windows
users (not tested on Linux), the scilex.exe scilab binary file can be
run with new undocumented options.
Noticeably, the "--help" one, that shows a list. From a cmd.exe shell:
>.\Scilab-6.0.2\bin\scilex --help
Usage: Scilab <options>
-e Instruction : execute the scilab instruction given in
Instruction argument.
-e and -f arguments are mutually exclusive.
-f File : execute the scilab script given in File argument.
-e and -f arguments are mutually exclusive.
-quit : force scilab exit after execution of script
from -e or -f argument.
this flag is ignored if it is not used with -e
or -f argument.
-l lang : Change the language of scilab ( default : en_US ).
-nw : Enable console mode.
-nwni : Enable terminal mode.
-ns : Don't execute etc/scilab.start.
--help : Display this help.
-scihome <dir> : Force SCIHOME to <dir>.
Developer Trace arguments:
--parse-trace : Display bison state machine evolution.
--AST-trace : Display ASCII-art AST to be human readable.
--pretty-print : Display pretty-printed code, standard Scilab
syntax.
Developer Timer arguments:
--AST-timed : Time each AST node.
--timed : Time global execution.
Developer Debug arguments:
--no-exec : Only do Lexing/parsing do not execute
instructions.
--context-dump : Display context status.
--exec-verbose : Display command before running it.
--timeout delay : Kill the Scilab process after a delay.
However, if i try to run this command from Scilab through a unix_*()
function, it returns nothing.
Nothing in the Scilab session, nothing in the consolebox...:
--> unix_w(WSCI+"\bin\scilex --help")
--> [re,s,e] = unix_g(SCI+"\bin\scilex --help")
e =
s =
0.
re =
[]
There is no space in my WSCI path.
This behavior looks like the bug 14143
<http://bugzilla.scilab.org/show_bug.cgi?id=14143> reported for Linux,
not confirmed for Windows, and fixed in Scilab 6.0.2.
Any confirmation or explanation would be welcome.
Regards
Samuel
