问题 What's the benefit and primary reason for compiling GNU gettext .po (Portable Object) files to .mo (Machine Object) ? I saw many programs reading/parsing .po directly. I'm not using wordpress but on their docs it says: https://codex.wordpress.org/I18n_for_WordPress_Developers PO files are compiled to binary MO files, which give faster access to the strings at run-time Is faster access true? PO can be read only once and cached in some hash table, the same probably goes for MO 回答1: There are

问题 My page requires localization. I use gettext. My i18n.__ function returns translated string and replaces %s symbols with provided arguments. As far as I know, I can't 'dangerously set' a JSX element, however I need to insert opening and closing <Link> tags. I can't split the string into multiple pieces because back-end provides me such. I am open to any ideas. Here's my div element: <div dangerouslySetInnerHTML={{ __html: i18n.__('Feel free to %scontact us%s if you have found a bug.', ['<Link

Java期末总结

阅读更多关于 Java期末总结

经过这一学期对java的学习，对java已经能够初步运用，就是有些有点不记得，得看书或网上查阅使用方法。相较C语言，java还是有很多大不同之处，却也有着许多相似之处我也就本学期所学总结一下： 1、先了解java并搭建开发环境jdk。 2、关键字this、static、super、final、instanceof、throw和throws。 this：（1）表示类中的属性；（2）可以使用this调用本类的构造方法；（3）this表示当前对象；（4）用this强调本类中的方法。 static：（1）使用static声明属性；（2）使用static声明方法。 super：使用super调用父类中的指定构造方法（语句必须放在子类构造方法的首行）。 final：（1）使用final声明的类不能有子类；（2）使用final声明的方法不能被子类所覆写；（3）使用final声明的变量即成为常量，常量不可以修改。 instanceof：用来判断一个对象到底是哪个类的实例。 throws：在定义一个方法的时候可以使用throws关键字声明，使用throws声明的方法表示此方法不处理异常，而交给方法的调用处处理。 throw：与throws关键字不同的是，可以直接使用throw关键字抛出一个异常。抛出时直接抛出异常类的实例化对象即可。 3、java中线程的实现：（1
