Colorized readline prompt breaks control-a

由 巧了我就是萌 提交于 2020-06-27 16:09:11
问题 The following program prints a colorized readline prompt. It breaks control-a (the cursor ends up much farther to the right than it should be): #include <readline/readline.h> #include <readline/history.h> #define CYELLOW "\001\e[0;31m\002" #define RESET "\001\e[0m\002" int main(int argc, char **argv) { readline(CYELLOW "prompt> " RESET); return 0; } control-a works when I call readline() without a colorized prompt: readline("prompt> "); I'm using Mac OS X 10.9.4. Here's the output of otool:

iPython does not read ~/.inputrc

由 强颜欢笑 提交于 2020-06-27 10:52:10
问题 I am using iPython. The docs says that I should be able to remap the readline library's keys using inputrc. Here is what I have in my inputrc: set editing-mode emacs set keymap emacs Meta-h: backward-word Meta-s: forward-word Control-h: backward-char Control-s: forward-char Control-n: previous-history Control-t: next-history Control-p: yank Meta-p: yank-pop These mappings simply do not work when I load iPython. I'm on OS X 10.9 Mavericks. I do not see any warnings that libedit is being used

Listen on ESC while reading Console line

由 ￣綄美尐妖づ 提交于 2020-06-25 09:42:56
问题 I want to read an users input into a string while still reacting on ESC press at any time, but without defining a system wide hotkey. So when the user types e. g. "Test Name" but instead of confirming with ENTER presses ESC he should be led back into main menu. Console.Write("Enter name: ") if (Console.ReadLine().Contains(ConsoleKey.Escape.ToString())) { goto MainMenu; } return Console.ReadLine(); Thats the simplest way I could think of, but since ESC is not seen by Console.ReadLine() it is

Msys2: readline in two python installations

问题 I am top-posting EDITs so the reader does not need to locate the current status. This is a specific question related to the two python installations mentioned in Msys2: Maintaining two python installations $ pacman -Sl | grep "python " | grep "installed" mingw64 mingw-w64-x86_64-python 3.8.2-2 [installed] msys python 3.8.2-1 [installed] EDIT #2 : It became clear that readline s quoted below were not python packages, but for shells.

第一点：Java代码实现文件上传 FormFile file = manform.getFile(); String newfileName = null; String newpathname = null; String fileAddre = "/numUp"; try { InputStream stream = file.getInputStream();// 把文件读入 String filePath = request.getRealPath(fileAddre);//取系统当前路径 File file1 = new File(filePath);//添加了自动创建目录的功能 ((File)file1).mkdir(); newfileName = System.currentTimeMillis() + file.getFileName().substring( file.getFileName().lastIndexOf('.')); ByteArrayOutputStream baos = new ByteArrayOutputStream(); OutputStream bos = new FileOutputStream(filePath + "/" + newfileName); newpathname = filePath + "/" +

【实践】切面打印请求参数

由 非 Y 不嫁゛ 提交于 2020-05-08 09:42:38
加打印语句，将请求参数打印出来。后面想想，以后可能还会遇到这样的情况，如果每次遇到，我都去对应的方法中加日志打印，就变成重复工作。并且日志打印跟我们的业务本身没有任何关系。 记录日志网上主要有三种方法： aop filter interceptor 我选择了filter。为什么选择它，因为我觉得它相对于定义切点，然后切点前后处理来说，更加方便；相对于 interceptor， 我更加熟悉这种方式。 定义Filter 定义一个 LogFilter 。 里面对 HttpServletRequest 进行拦截，根据对应的 content-type 解析请求参数。主要代码如下 /** * 功能描述: 打印请求参数 * @author lkb * @date 2020/5/6 * @param * @return */ @Slf4j public class LogFilter extends OncePerRequestFilter { @Override protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException { // 日志 doLog
