I'm tying to put in a command that goes
{11,21}STO>dim([A])
And I keep getting a syntax error at the first square bracket. The syntax seems correct to me, so I don't know what the issue is.
Your syntax appears to be right. The only tip I can give you is a list of button presses to make sure for example you are not doing Bracket A Bracket but selecting the matrix from the matrix menu.
The button presses to do the task you appear to want are:
2nd->left brace(left parenthesis button)->1->1->,->2->1->2nd->right brace(right parenthesis button)->sto(->)->2nd->matrx(x^-1 button)->right arrow->3->2nd->matrx(x^-1 button)->1->right parenthesis
I hope this can be of help, let me know if it works or not.

can anyone show me how editor.autoClosingOvertype works in vscode settings? thank you very much
Overtype mode allows you to type the SAME character as the next character and NOT have that same character added again but act as if you typed the same character on top of that already existing character.
It is used by people who want to keep their hands on the keyboard and simply type the next character to get PAST it. It can be much faster to simply type the next character if you want to get past it (rather than right-arrowing past it) but you don't want two of those characters.
In this case you asked about overtyping and the editor.autoClosingOvertype which applies to quotes or brackets. There are three options for that setting.
never means when you type the quote or closing bracket (when you are right before it) - it is NOT typed over and another quote or closing bracket is simply added where you typed it.
always means always overtype that next closing quote or bracket no matter how it might have been inserted in the first place. Sometimes those quotes/brackets were added automatically by the vscode language server and sometimes by another method (like a snippet).
auto - the default will overtype that next closing quote or bracket only when it was automatically added by the vscode language server and not when it was added by any other means.
So, let's say I select a closing brace. I want eclipse to not only highlight the matching opening brace, I want it to show me its whole line on the top of my editor, no matter how higher up it is. I'm sure I've seen it on some other IDE, is it possible to do on Eclipse? For example, if it's a closing brace for an if statement, I want to see the opening of this if to see its condition. This could also apply to methods, loops, etc.
If not showing the whole line, I would at least like to highlight the whole line with a color that stands out, so that I can find it easier through scrolling. I know I can jump there with Ctrl+Shift+P, but it's not always practical.
I'm trying to make a graphical editor in Racket using List of characters, but I can't figure out how to write a left and right arrow as a character.
I've tried #\right and #\rightarrow but neither works.
I expected it to work because #\backspace does work, especially because "\b" works as a string and "left" and "right" also work as strings for left arrow and right arrow.
The list of characters with names are here:
https://docs.racket-lang.org/reference/reader.html?q=characters#%28part._parse-character%29
I am not sure what you mean by "left space" and "right space" though.
I want to know if there is a way to highlight the full content in an expression like if, while, etc.
I have to work in a code that is bad indented where expressions can cover over 1000 lines and I can't format it.
for exemple :
if ($somethingTrue) {
while ($somethingHappen) {
// 500 lines...
} }
if ($someCondition) {
}
look, it's very hard to see the end of the first if and what it cover...
Does someone know if there is a native feature or plugin on netbeans that do this job ?
Thanks !
You don't need any plugin/external jar file for achieving the same. Whichever expression you want to check the body of, just click on the opening brace after that expression and NetBeans will automatically show you the closing brace for that expression.
Basically, Netbeans shows the ending brace for a corresponding starting brace entry---for each of if-statements,loop-statements,method declarations,etc.
In the shown figure, see my if-statement starting with yellow brace(cursor blinking there), and the corresponding ending brace for the if-statement.
EDIT :-
You also can also have a brand new-code fold,just by typing fcom, and hitting (Tab) button on KeyBoard. And, then put whatever block you want inside it and done. Expand whenever you wish and collapse whenever you want.
Check the position of my mouse-pointer which shows the current block of if-statement. You can expand and collapse as per your wish. And, also you can have several of them for each of your expression-tree.
I would like to replace the right square bracket "]" with ",1]". Usually I use M-% to do replacement, but for this case it does not work and gives: No matching parenthis found. I tried to replace left square brackets and it works. Does someone can give me a hint how I can replace right square brackets?
Thanks for help.
"No matching parenthesis found" is a useless warning here. Just ignore it. Consider this warning a bug, as it seems useful only WRT to regexps.
