path

问题 I'm not a regex expert and I'm breaking my head trying to do one that seems very simple and works in python 2.7: validate the path of an URL (no hostname) without the query string. In other words, a string that starts with /, allows alphanumeric values and doesn't allow any other special chars except these: / , . , - I found this post that is very similar to what I need but for me isn't working at all, I can test with for example aaa and it will return true even if it doesn't start with / .

问题 I read that "Strings longer than ${NSIS_MAX_STRLEN} (1024) will get truncated/corrupted." How can I safely update %PATH% environment variable ? 回答1: You can use an alternative NSIS build from the special builds page like the large strings build that defines NSIS_MAX_STRLEN=8192 and should prevent you from breaking the host path. In practice, on a desktop machine, 1024 byte seems enough, but on a development host with many tools installed (like mine), the path might be broken after

问题 The question of how to set PATH for all programs in a user session (not just Terminal) has come and been addressed. So I changed both /etc/launchd.conf AND /etc/paths, just to make sure everything was ok. However, I am still getting a different PATH envar when I launch Terminal than what I'm expecting (I'm not at all sure how to test PATH from another application.) Here's what's in /etc/launchd.conf: setenv PATH /sw/bin:/sw/sbin:/sw/local/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr

问题 Just wondering how I might go about drawing arrow heads along a path. The path will change direction and go through several different points. The arrow heads are designed to show the user which direction along the path they need to travel. I've tried to use a brush but it didn't work as I need the arrow heads to orientate them selfs along the path... 回答1: See Path Animations Overview and MatrixAnimationUsingPath It can be used to move a control along a PathGeometry and if you set

问题 My current document URL is http: //127.0.0.1/foo and I need to change the value of a cookie for http: //127.0.0.1/bar. document.cookie is empty because document's URL is foo. For the moment, I just want to read the cookie value. Any clue? 回答1: When you create the cookie, if you set the path to '/' instead of 'foo' you will be able to read it anywhere on the domain, including '/foo', '/bar', etc. 回答2: You can create an <iframe> pointed at a resource inside /bar , and cross-frame-script into it

问题 I installed Homebrew on OS X El Capitan. In the last steps of the installation I was supposed to install git with brew install git which was fine.
