Git alias - seja rápido, seja breve!

Git alias - seja rápido, seja breve!

Git freak como sou, precisava compartilhar algo útil sobre ele, claro. E, já que não vejo muito por aí o pessoal usando, resolvi falar dos alias do git! É um recurso que eu uso muito, e nunca entendi porque muitas pessoas não são adeptas. 😕

Pelo nome você já deve perceber que os alias no git são atalhos. Atalhos pro quê? São atalhos para comandos do git e até comandos shell se você quiser. E é bem fácil cadastrar um alias:

$ git config --global alias.st status

Fixes an issue with Google Chrome Speech Synthesis where long texts pause mid-speaking. The function takes in a speechUtterance object and intelligently chunks it into smaller blocks of text that are stringed together one after the other. Basically, you can play any length of text.
