关于吾爱论坛新增IL语言支持的原理和测试与使用

lizhirui

恭喜吾爱论坛支持新的语言——IL语言(我干的)，即.net中间语言的语法着色。
望大家看完觉得本帖好的话不要忘记评个热心值。
使用方法如下：

如果使用过程中出现如下提示：

其原因是浏览器缓存未刷新，请清空浏览器缓存后再次尝试，或者打开https://avatar.52pojie.cn/mw_syn ... ushIL.js?ver=3.0.83这个链接，查看“Brush.aliases        = ['il'];”行中的il是否为小写，此处原因是因为刷子文件缓存的原因，导致新版本js文件未加载。

以下是测试代码，希望大家可以对着色效果提出一些意见或者建议：

原理如下：
论坛使用的是mw_syntaxhighlighter插件，
我们打开源码目录（默认位于discuz论坛下的source/plugin/mw_syntaxhighlighter目录下）看到如下文件：

我们打开discuz_plugin_mw_syntaxhighlighter_SC_UTF8.xml文件，看到如下内容：

这样修改完后，还需要修改discuz数据库：
我们在discuz数据库中找到表"pre_common_pluginvar"（其中pre_为discuz论坛安装时的表前缀）
会发现这么一项：

我们修改description字段为：

[Plain Text] 纯文本查看 复制代码

选择支持的语言，按住Ctrl键可多选
注意：AppleScript、Sass、Scss、IL四种语言仅在3.x高亮版本库中支持

修改value字段为：

[Plain Text] 纯文本查看 复制代码

a:41:{i:0;s:11:"applescript";i:1;s:13:"actionscript3";i:2;s:4:"bash";i:3;s:10:"coldfusion";i:4;s:1:"c";i:5;s:3:"cpp";i:6;s:6:"csharp";i:7;s:3:"css";i:8;s:6:"delphi";i:9;s:4:"diff";i:10;s:6:"erlang";i:11;s:6:"groovy";i:12;s:4:"html";i:13;s:4:"java";i:14;s:6:"javafx";i:15;s:10:"javascript";i:16;s:6:"pascal";i:17;s:5:"patch";i:18;s:4:"perl";i:19;s:3:"php";i:20;s:4:"text";i:21;s:10:"powershell";i:22;s:6:"python";i:23;s:4:"ruby";i:24;s:5:"rails";i:25;s:4:"sass";i:26;s:5:"scala";i:27;s:4:"scss";i:28;s:5:"shell";i:29;s:3:"sql";i:30;s:2:"vb";i:31;s:5:"vbnet";i:32;s:5:"xhtml";i:33;s:3:"xml";i:34;s:4:"xslt";i:35;s:4:"objc";i:36;s:3:"asm";i:37;s:5:"aauto";i:38;s:6:"golang";i:39;s:3:"lua";i:40;s:2:"il";}

修改extra字段为：

[Plain Text] 纯文本查看 复制代码

applescript = AppleScript
actionscript3 = Actionscript3
bash = Bash shell
coldfusion = ColdFusion
c = C
cpp = C++
csharp = C#
css = CSS
delphi = Delphi
diff = Diff
erlang = Erlang
groovy = Groovy
html = HTML
java = Java
javafx = JavaFX
javascript = JavaScript
pascal = Pascal
patch = Patch
perl = Perl
php = PHP
text = Plain Text
powershell = PowerShell
python = Python
ruby = Ruby
rails = Ruby on Rails
sass = Sass
scala = Scala
scss = Scss
shell = Shell
sql = SQL
vb = Visual Basic
vbnet = Visual Basic .NET
xhtml = XHTML
xml = XML
xslt = XSLT
objc = Objective-C
asm = Asm
aauto = AAuto
golang = Golang
lua = Lua
il = IL

然后保存即可，我们进入discuz后台，进入插件配置，这么修改：

然后提交修改后，刷新网站缓存即可。

思路很赞！补充一点数据库其实不用手动修改，把 xml 里的版本号改大，覆盖原插件文件后在dz后台选择“升级”即可。

@lizhirui 请问我上一个帖子被认为广告贴https://www.52pojie.cn/thread-821318-1-1.html
是因为我发帖的内容，还是帖子附件里进游戏的封面带QQ什么的？   能指明一下吗？很多人等着我再发一波呢，我都不敢搞了。
