std::string nix::filterANSIEscapes | ( | std::string_view | s, |
bool | filterAll = false, | ||
unsigned int | width = std::numeric_limits< unsigned int >::max() ) |
Truncate a string to 'width' printable characters. If 'filterAll' is true, all ANSI escape sequences are filtered out. Otherwise, some escape sequences (such as colour setting) are copied but not included in the character count. Also, tabs are expanded to spaces.
std::pair< unsigned short, unsigned short > nix::getWindowSize | ( | ) |
The value is cached so this is quick. The cached result is computed by updateWindowSize()
.
bool nix::isTTY | ( | ) |
Determine whether ANSI escape sequences are appropriate for the present output.
void nix::updateWindowSize | ( | ) |
Recalculate the window size, updating a global variable.
Used in the SIGWINCH
signal handler on Unix, for example.
