Set
设定ruby-debug的环境，Boolean变量可以设定为on off或者1 0 设定变量可以用show显示
set annotate # 设定注释等级
set args # 设定变量列表,用来传递给运行环境
-
set autoeval # 在不能直接输出的表达式,进行eval计算

set autoirb # 任何时候只要stop则执行irb
set autoreload # 当代码有修改的时候,从新load
set basename # 设定basename只显示文件名
set callstyle # 设定显示变量格式
set debuggertesting # 用于测试debugger自身
set forcestep # 保证'next/step'命令总是能向新行移动
set fullpath # 在frames中显示文件的完整路径名
set history # Generic command for setting command history parameters
set keep-frame-bindings # Save frame binding on each call
set linetrace+ # Set line execution tracing to show different lines
set linetrace # Set line execution tracing
set listsize # Set number of source lines to list by default

Thread
用于线程操作
th[read] l[ist] # 列出所有的线程
th[read] stop <nnn> # 停止指定线程
th[read] resume <nnn> # 恢复指定线程
th[read] [sw[itch]] <nnn> # 切换执行环境到指定线程
th[read] [cur[rent]] # 显示当前线程
Trace
tr[ace] (on|off) set trace mode of current thread
tr[ace] (on|off) all set trace mode of all threads
