Xcode 調(diào)試工具 Chisel 的安裝與使用

Chisel 是 Facebook 出品的一個(gè)功能強(qiáng)大的調(diào)試工具江兢。主要用來(lái)擴(kuò)展原有的 LLDB 調(diào)試命令。

環(huán)境配置

• 首先您的電腦要安裝 homebrew 打開(kāi)終端窗口, 粘貼以上腳本

    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  

終端顯示

    zqldeMacBook-Pro:~ zql$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    ==> This script will install:
    /usr/local/bin/brew
    /usr/local/Library/...

    /usr/local/share/man/man1/brew.1
    /usr/local/share/zsh/site-functions/_brew
    /usr/local/etc/bash_completion.d/brew
    ==> The following directories will be made group writable:
    /usr/local/.
    /usr/local/bin
    /usr/local/sbin
    ==> The following directories will have their owner set to zql:
    /usr/local/.
    /usr/local/bin
    /usr/local/sbin
    ==> The following directories will have their group set to admin:
    /usr/local/.
    /usr/local/bin
    /usr/local/sbin
    
    Press RETURN to continue or any other key to abort
    ==> /usr/bin/sudo /bin/chmod g+rwx /usr/local/. /usr/local/bin /usr/local/sbin
    Password:
    ==> /usr/bin/sudo /usr/sbin/chown zql /usr/local/. /usr/local/bin /usr/local/sbin
    ==> /usr/bin/sudo /usr/bin/chgrp admin /usr/local/. /usr/local/bin /usr/local/sbin
    ==> /usr/bin/sudo /bin/mkdir /Library/Caches/Homebrew
    ==> /usr/bin/sudo /bin/chmod g+rwx /Library/Caches/Homebrew
    ==> /usr/bin/sudo /usr/sbin/chown zql /Library/Caches/Homebrew

    Run `brew help` to get started

• 終端輸入：brew install chisel

    zqldeMacBook-Pro:~ zql$ brew install chisel
    ==> Downloading https://github.com/facebook/chisel/archive/1.4.0.tar.gz
    ==> Downloading from https://codeload.github.com/facebook/chisel/tar.gz/1.4.0
    ######################################################################## 100.0%
    ==> Caveats
    Add the following line to ~/.lldbinit to load chisel when Xcode launches:
    command script import /usr/local/opt/chisel/libexec/fblldb.py
    ==> Summary
    ??  /usr/local/Cellar/chisel/1.4.0: 22 files, 109.5K, built in 7 seconds
    zqldeMacBook-Pro:~ zql$         
  

• 從終端中可以看Caveats下面的那兩行惶洲，意思是把第二行的文字command script import /usr/local/opt/chisel/libexec/fblldb.py添加到.lldbinit文件中，這時(shí)執(zhí)行命令echo command script import /usr/local/opt/chisel/libexec/fblldb.py >> ~/.lldbinit（粗體文字替換為你終端Caveats下面的第二行文字）可免去你去找.lldbinit文件膳犹，或者.lldbinit文件不出現(xiàn)的煩惱啊恬吕。到此步不出意外已經(jīng)安裝成功。

如圖所示
