Seperate shell history for each terminal window

It was a version from 2019.  I do not have the actual version anymore.  

I have this shell function in my my environment but I am not sure where it came from:
configureCommandHistory () 
{ 
   local commandHistoryFile="$__INTELLIJ_COMMAND_HISTFILE__";
   unset __INTELLIJ_COMMAND_HISTFILE__;
   if [ -n "$commandHistoryFile" ] && [ -z "`trap -p EXIT`" ]; then
       trap "$(builtin printf 'history -w %q; HISTFILE=%q' "$commandHistoryFile" "$HISTFILE")" EXIT;
       if [ -s "$commandHistoryFile" ]; then
           HISTFILE="$commandHistoryFile";
       fi;
   fi
}
 

I only have that in the PyCharm terminal.  It is not in my other terminal emulators.

Based on snippet I have create solution purely in bash. It could (if you want) work for non Jetbrains terminals.
In my case it was enough to distinguish basing on current working directory - so terminal will restore its history depending on directory in which it was opened.

Script:

#!/bin/bash

HISTORY_DIR=/home/$USER/.bash-session/

cleanStr () {
    local a=${1//[^[:alnum:]]/-}
    echo "${a,,}"
}

# history setup
shopt -s histappend

# clean and immediately append new entries

export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND"

# detect if the terminal is a JetBrains terminal
if [[ "$TERMINAL_EMULATOR" == "JetBrains-JediTerm" ]]; then
    # create the history directory if it doesn't exist
    if [ ! -d $HISTORY_DIR ]; then
        mkdir $HISTORY_DIR
    fi

    # set the history file
    TERMID=$PWD
    HISTORY_FILENAME=$(cleanStr $TERMID)
    HISTORY_FILEPATH="$HISTORY_DIR$HISTORY_FILENAME"

    echo "JetBrains terminal detected. Configuring command history."
    echo "ID: $HISTORY_FILENAME"

    # configure the command history
    export HISTFILE=$HISTORY_FILEPATH
fi

In `~/.bashrc` put `source <path-to-script>` or just put whole script into `.bashrc`
