Don't add current command to history (`ignore` flag) about zsh-hist HOT 2 CLOSED

That's already possible in Zsh natively. You have three options for this, all of which can be combined:

• Add setopt HIST_IGNORE_SPACE to your .zshrc file. Then, if you insert at least one space at the very beginning of a command line, it will not be saved to history, although it is still saved to local history in memory.
• Add HISTORY_IGNORE=<glob pattern to your .zshrc file. Then, any command line that matches that pattern will not be saved to history.
• Add a history hook function to your .zshrc file:

  autoload -Uz
  <function>() {
    <logic>
  }
  add-zsh-hook zshaddhistory <function>

  Then, whenever you submit a command line, before it is executed, it will be passed to this function. If the function returns 1, it will not be saved. If it returns 2, it will be saved to local history in memory, but will not be saved to the $HISTFILE. Returning 0 will save the command line to history, unless prevented by one of the other two options.

@marlonrichert Thank you for the detailed explanation, it makes sense to do it this way. Very useful.
