Hello Federico, Sorry if this answer breaks the thread (despite you have forwarded your initial message to me with its full header. Thanks):
Le 21/12/2022 à 03:15, Federico Miyara a écrit : Dear All, I have to create a vector from a plain text containing about 700 decimal numbers, each one with several digits. The total character count incuding spaces is about 5700, so when I run this command I get the following error: "Command is too long (more than 4096 characters long): could not send it to Scilab" Is there a simple way to do this other than splitting the text into two parts, each one with less than 4096 digits and then concatenating the vectors, or saving the data as a text file and reading the file into a string variable and converting to numbers? Thanks, Federico Miyara Federico Miyara<https://www.mail-archive.com/search?l=users@lists.scilab.org&q=from:%22Federico+Miyara%22> Thu, 17 Nov 2022 13:22:08 -0800<https://www.mail-archive.com/search?l=users@lists.scilab.org&q=date:20221117> Christopher, Yes, you understand correctly my case. There is a reason that justifies my request: I often use my scripts as examples within a didactic context. They are exhaustively commented, for instance. I consider it preferable to have all the needed data in the same script since I cannot be sure that potential future users who find my script will also find the associated file with the data (sometimes one downloads a file for future use without checking whether we are downloading all the associated files).Then they should also change the script according to the particular directory tree where they choose to place the data, which is an unnecessary distraction from the very point of the example.I agree that it wouldn't be convenient nor practical to work in this way with very large data sets, but some 1000 data is not unusual. Regards, Federico Miyara I fully understand and share your concern. I noticeably encountered a similar situation and requirement during last summer, to build some Scilab tests applied to some "passive extra content". In the PHP language (that kept me busy for ~9000 hours in another life), i remembered some ob_start(..) .... ob_end(..) instructions: In a PHP script, all multi-line contents lying between these two statements are send to a buffer, instead of being executed. Then for instance it is possible to get this content in a string array, with $myarray = ob_get_contents(). For Scilab, a similar feature can be implemented by putting the "passive content" in a /* multiline block of comments */. Thus, i have implemented a get_blockcomment() function to read some block-comment in the Scilab script being currently executed. The supported syntaxes are: r = get_blockcomment() : reads and returns the next block-comment following this call. r = get_blockcomment(n) : reads and returns the nth block-comment of the current file. with r: column of text Option doEval (boolean): evaluates the content and returns the results e instead of it: e = get_blockcomment( , %t) e = get_blockcomment(n, %t) If no block-comment can be read, [] is returned. The unitary tests file of this function is attached. This function was first implemented as an internal one. But afterwards, like you, i've thought that it is a general usage function, and indeed i use it as well in other contexts. I think it would be useful in Scilab. Would this be right? Maybe its name could be improved.
