问题 Is it possible to select a piece of text you're editing and change its color? I know it's possible to create a color theme that will color certain kinds of text (like for example coloring functions in a certain programming language), but is it possible to do a one time color change to a selected piece of text in a specific emacs document without creating a theme? thanks in advance. 回答1: A theme doesn't allow you to specify the color of arbitrary text in any case. It only describes a set of

问题 My Mac came with Python 2.7 installed by default, but I'd like to use Python 3.6.1 instead. How can I change the Python version used in Terminal (on Mac OS)? Please explain clearly and offer no third party version manager suggestions . 回答1: The simplest way would be to add an alias to python3 to always point to the native python installed. Add this line to the .bash_profile file in your $HOME directory at the last, alias python="python3" Doing so makes the changes to be reflected on every

问题 I've been Googling for a while looking for a simple way to do this, and I can't find one. I have a custom terminal environment set up (zsh) with various aliases and functions to make things easier. One thing I keep running into is that I will quickly APPLE-t to create a new tab and then type a command relative to the path of the terminal window I was just in.

问题 I have created an 'External Build Project' in Xcode 4 using a makefile. The project builds perfectly, except the only way I know how to get it to run is in Terminal. Is there a way I can run the program in Xcode 4 or is Terminal it ? 回答1: Yes, you need to create a Custom Executable, so that Xcode knows where your built executable resides and how to run it. In Xcode 3 it's Project -> New Custom Executable... . This will allow you to to run your executable and even do source level debugging if

问题 I have an array called "loop". For each element in "loop" I want to create an array whose name contains the text of the current element. I then want to loop through each new array and print every element from each array. This post seems to have a good solution for variables but I do not know how to adapt it to work for arrays. My Script #!/bin/bash loop=( first second third ) for word in "${loop[@]}" do declare "${word}_holder=( hello world )" var="${word}_holder" echo "$var" for i in "${!var
