编码时我讨厌粗体文字.是否可以在每个文件和emacs的界面中禁用粗体文本(和下划线)？

该网站仅提到缓和选项:

# easing: Name of the easing equation.

但没有例子.

如何使用此功能？

可能重复:将
Scala文件加载到解释器中以使用函数？

我像这样启动sbt控制台:

alex@alex-K43U:~/projects$ sbt console
[info] Set current project to default-8aceda (in build file:/home/alex/projects/)
[info] Starting scala interpreter...
[info] 
Welcome to Scala version 2.9.2 (OpenJDK Client VM, Java 1.6.0_24).
Type in expressions to have them evaluated.
Type :help for more information.

scala>

我有一个test.scala(/home/alex/projects/test.scala)文件,如下所示:

def timesTwo(i: Int): Int = {
  println("hello world")
  i * 2
}

如何做到这一点,我可以在控制台中做这样的事情:

scala> timesTwo

并输出函数的值？

Vim完成了单词和行,CTRL-X P并且CTRL-L.有一个名为Company模式的Emacs插件,但是这个插件会干扰并导致与Emacs中的许多内容发生冲突(使用全局linum和yasnippets).我知道我可以在Emacs中使用CTRL- /来完成单词.但是有可能采用以前写过的行来完成代码吗？

我正在按照本教程使用PHP gettext构建多语言网站http://onlamp.com/pub/a/php/2002/06/13/php.html

直到这部分,我理解教程:

在准备好所有目录之后,是时候创建实际的"pot"文件,因为它通常被称为:messages.po文件.为此,您需要使用gettext()函数的PHP文件来"标记"要翻译的字符串并使用xgettext命令.

$ xgettext -n *.php

我是否必须在命令行中编写它？我执行该命令时必须在哪个文件夹中？这是该命令的Linux版本还是Windows？

(我在我的wamp ini文件中启用了gettext扩展)我是否必须从GNU网页下载gettext utilites才能创建.po文件？

到目前为止,我见过的关于使用gettext而不是数组的唯一两件好事是我不必创建"问候""子数组"(或其所谓的).而且我不必为"默认语言"创建文件夹.

是否有其他使用gettext和php数组用于多语言网站的优点和成本？

使用GETTEXT:

西班牙/ messages.po:

#: test.php:3
msgid "Hello World!"
msgstr "Hola Mundo"

index.php文件:

<?php echo _("Hello World!"); ?>

？的index.php LANG =西班牙语:

<?php echo _("Hello World!"); ?> turns to Hola Mundo

使用PHP ARRAYS:

lang.en.php

<?php
$lang = array(
    "greeting" => "Hello World",
);
?>

lang.es.php

<?php
$lang = array(
    "greeting" => "Hola Mundo",
);
?>

index.php文件:

<?php echo $lang['greeting']; ?> greeting turns to Hello World

的index.php？LANG =西班牙语

<?php echo $lang['greeting']; ?> greeting turns to Hola Mundo

(我首先使用gettext,但我的共享免费托管Zymic不支持.我不想使用Zend_translate,我发现它对我的简单任务来说太复杂了,所以我最终使用了php define,但后来又有人告诉我应该使用数组)

我刚刚更新到Rails 3.2并在启动WEBrick后出现以下错误:

[DEVISE] devise.registrations.reasons in yml files is deprecated, please use devise.registrations.signed_up_but_REASON instead. The default values are:

      signed_up_but_locked: 'You have signed up successfully. However, we could not sign you in because your account is locked.' …

我正在尝试安装Flask,但我打赌所有这些警告和错误:

当我开始时,sbt console我得到了这个:

alex @ alex-K43U:〜$ sbt console [warn]替代项目目录.sbt(/home/alex/.sbt)自sbt 0.12.0以来已被弃用.[warn]
请使用标准位置:/ home/alex/project [info]从/home/alex/.sbt加载项目定义[info]将当前项目设置为default-22b2b7(在构建文件中:/ home/alex /)

我刚开始使用scala和sbt,所以我不确定警告意味着什么.这意味着我必须将所有内容/home/alex/.sbt移至/home/alex/project？

(我也有这个文件夹:/home/alex/sbt它有一个bin文件夹和一个jansi-license.txt文件.我认为这是我安装sbt的方式).
