A: What guarantees does Bash make about order of :- Parameter Expansion when it is not in POSIX mode? > The documentation seems to me to hint that WORD will be expanded whether I want it to be, or not. I don't agree, because as quoted: > (1) If PARAMETER is unset or null, the expansion of WORD is substituted. > (2) Otherwise, the value of PARAMETER is substituted. Case 2 is the one at han...

Qt Button changes drastically when setting its `border-radius`. In a Qt application I have nothing more than a window with a button as its direct child. I set its background color and all is fine: ``` Window::Window(QWidget parent) : QWidget(parent) { button1 = new QPushButton(this); button1->setText("1234"); button1->setStyleSheet("{backg...

A: How to manage user-specific application data on Linux? Indeed, the `$HOME/.application-name` is the old way. Doing that nowadays is frowned upon (this is an example of what happens if you try), mostly because, as you said, it clutters the home directory.

A: Vim: how to search for all instances of a string, except for those that are between two specific strings Alternating between the two patterns seems to work! \(abc.\)\@<!bird\|bird\(.xyz\)\@! As a bonus, you can enable the very magic mode with `\v` to avoid backslashes! The resulting expression is equivalent but easier to type. \v(abc.)@<!bird|bird(.xyz)@! For reference: `:help /bar` ...

console.readline tag does not look good to me The console.readline tag has been created for Q: How to read lines into an array in Bash, which uses a `while read` loop. That tag is inappropriate because Readline, the console and the `read` built-in are mostly unrelated concepts, and only the latter is part of the question. Please consider ... (more) |

A: How to read lines into an array in Bash 1st issue As others have said, `echo "$array"` only prints the first element of the array; I suggest printf '%s\n' "${array[@]}" to print each element on a line. 2nd issue More importantly, the loop is partially incorrect. Consider this file: ``` pear yellow apple \\ red ... (more) |

Warn of implicit cast in a function's arguments with GCC? In the C program below, I make a mistake and call the function with `(ld, ld)` instead of `(d, ld)`. ```c #include #include void printintlong(int n, long l){ printf("%+d %+ld\n", n, l); } int main(){ int d = 0; long ld = INTMAX + 1L; printintlong(ld, ld); retu...
