Polish spell checking for PhpStorm

aspell --lang pl dump master | aspell --lang pl expand | tr ' ' '\n' > polish.dic

Next you go to settings, for single project or you can also set it as default (default setting wouldn’t apply to old procjects). Type in search “Spelling” change tab to “Dictionaries”, click + button to add folder where generated dictionary is placed. Apply. If not working, try to reboot PhpStorm.
