Code challenge: Bash prompt path shortener

阅读更多关于 Code challenge: Bash prompt path shortener

问题 I implemented a prompt path shortener for bash to be included in the PS1 environment variable, which shortens the working directory into something more compact but still descriptive. I'm curious what other ideas may exist. Here's the challenge: Create a bash function _dir_chomp which can be included into PS1 like this (line breaks inserted for readability): PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] $( _dir_chomp "$(pwd)" 20 )\[\033[01;37m\]$(parse_git_branch)\[\033[01;34m\] \$\[\033[00m\] '

Shell Prompt Line Wrapping Issue

阅读更多关于 Shell Prompt Line Wrapping Issue

问题 I've done something to break my Bash Shell Prompt in OS X (10.5.7) Terminal. This is the PS1 that I had configured: PS1='\[\e[1;32m\]\h\[\e[0m\]:\[\e[1;34m\]\w\[\e[0m\]\$ ' As far as I can tell I have the color commands escaping correctly. However when I scroll up and down in my command history I often get line wrapping issues if the historic commands wrap onto multiple lines. I simplified my prompts to the following: PS1='\[\e[1m\]\h:\w\$ \[\e[0m\]' PS2='> ' And I still see something like:

json xhr response opens a download file popup window

For one of our ajax request (with a .json response) some of our clients have complained that they are seeing a "File Download" prompt asking the user to download the .json response. I am baffled because considering that this is an xhr response, this should never happen. Has anyone seen this? Thanks Reza For people who are using ASP MVC and have the same problem with IE, use this when returning your response: return Json(result, "text/plain"); Edit: the standard type is: "application/json", but does not work with IE. using text/html is dangerous. try specifying a MIME type of "text/plain" in

anaconda3安装失败，要么不报错，要么failed create menus

阅读更多关于 anaconda3安装失败，要么不报错，要么failed create menus

环境为winserver2008，就是开机菜单栏中anaconda3文件夹下面，只有一个prompt，其他啥都没有，prompt链接的快捷方式指向的文件也找不到。试过各种办法，最后发现，menu文件夹下根本就只有一个prompt的json，所以肯定是中间遇到了比较恶心的问题才不报错。用everthing搜一下python这个关键字，发现某个角落里还藏着不知道谁什么时候安装的某个版本的python，看来是在path中先找到了这个python，果断给删了。然后就work了，菜单栏里面各种图标都有了。用别人动过的电脑就是坑。文章来源: anaconda3安装失败，要么不报错，要么failed create menus

Don't make me manually abort a LaTeX compile when there's an error

阅读更多关于 Don't make me manually abort a LaTeX compile when there's an error

问题 As suggested here, latexmk is a handy way to continually compile your document whenever the source changes. But often when you're working on a document you'll end up with errors and then latex will panic and wait for user input before continuing. That can get very annoying, especially recently when I hacked up something to compile latex directly from an etherpad document, which saves continuously as you type. Is there a setting for latex or latexmk to make it just abort with an error message

Hi, 各位亲爱的小伙伴们！首先，JQData是基于python的一个数据包，所以安装JQData的第一步是安装Python （没有接触过python或者python基础不好的小伙伴，可以关注聚宽量化课堂的python讲堂进行python学习）。对于python安装包的选择，小编建议下载Anaconda，因为Anaconda提供了许多非常强大的工具包，小伙伴们只要下载安装Anaconda，就可以直接使用，而不需要挨个查找安装。小编在这里为大家提供Anaconda的下载地址。在下载界面，可以看到Anaconda有两个大版本，一个是python 2.7 Version，一个是python 3.6 Verson。熟悉python的小伙伴可以根据自己的喜好进行版本选择。对于不熟悉Python的小伙伴，小编推荐下载 python 3.6 Version ，因为在以后的使用中，可能发现有些工具包是不兼容python2.7的，而且JQData对于python3.6的兼容性是要强于python2.7的。确定好python版本，下载时还需要确认自己的系统位数，不清楚系统位数的小伙伴，可以参看百度经验。查到自己电脑的位数后，选择下载对应的安装包即可。如果小伙们发现自己下载的网速慢的话，小编给大家提供一个镜像网站，这个是清华大学的开源软件镜像站地址，由于使用的是国内的服务器

Automatically timing every executed command and show in Bash prompt? [duplicate]

阅读更多关于 Automatically timing every executed command and show in Bash prompt? [duplicate]

This question already has an answer here: How can the last command's wall time be put in the Bash prompt? 11 answers I often happen to forget to explicitly prefix executions with the "time" command, ideally I would see in the next shell prompt how much real time the last command took (on every command). I already scoured through the bash documentation, but couldn't find anything related. Dennis Williamson You could do this: $ bind '"\C-j": "\C-atime \C-m"' Or put this in your ~/.inputrc : "\C-j": "\C-atime \C-m" Then when you want to do time sleep 1 you'd type sleep 1 and press Ctrl + J
