在Sublime Text 3安装PlantUML插件
安装插件重新打开sublime时报错：unable to load diagram plugin, check console for details.
敲击快捷键alt+M时显示No diagrams overlap selections.nothing to process.
网上通常的解决办法是：修改\Sublime Text 3\Packages\plantumlpluginDiagram.sublime-settings，其中第三行将编码方式”charset”: null改为”charset”: “UTF-8”，关掉sublime Text 3重启,但是该方法并没有解决我的问题。
最简单的方法就是去查看console日志。
查看sublime的console
点击 Sublime 菜单 View -> Show Console，分析错误log。

发现：The environment variable GRAPHVIZ_DOT has not been set
解决办法：原来安装Graphviz之后，还需要配置环境变量。
D:\Program Files (x86)\Graphviz2.38\为我的解压目录
变量名：PATH
变量值：D:\Program Files (x86)\Graphviz2.38\bin
变量名：GRAPHVIZ_DOT
变量值：D:\Program Files (x86)\Graphviz2.38\bin\dot.exe
配置之后重新运行，console日志又报错：
b'The environment variable GRAPHVIZ_DOT has been set to D:\\Program Files (x86)\\Graphviz2.38\\bin\\dot.exe\r\nDot executable is D:\\Program Files (x86)\\Graphviz2.38\\bin\\dot.exe\r\nDot version: dot - graphviz version 2.38.0 (20140413.2041)\r\r\nInstallation seems OK. File generation OK\r\n'

代码\Sublime Text 3\Packages\plantumlplugin\diagram\preview.py如下：
from .base import BaseViewer
from subprocess import check_call, Popen as run_command
from sublime import platform
class PreviewViewer(BaseViewer):
def load(self):
if platform() not in ("osx",):
raise Exception("Currently only supported on MacOS")
if not check_call("which open > /dev/null", shell=True) == 0:
raise Exception("Can't find open")
def view(self, diagram_files):
displaycmd = ['open', '-a', 'Preview']
displaycmd.extend(diagram_file.name for diagram_file in diagram_files)
run_command(displaycmd).wait()
原来下载的插件版本不正确，后续会更新windows下可用的plantuml for sublime插件下载地址。
使用jar包绘制UML图
- 下载plantuml.jar,地址
- test.txt里写plantuml代码
- java -jar ./plantuml.jar test.txt
- 图片test.png效果展示
实际上，插件也主要是依靠jar包绘图Sublime Text 3\Packages\plantumlplugin\diagram\plantuml.1.2018.1.jar
不过也许是版本的原因，插件里的jar包也不能成功绘图。
plantuml生成的图片中文注释乱码问题解决
java -Dfile.encoding=utf-8 -jar ./plantuml.jar test.txt
简单说就是默认字符集是在 java 虚拟机启动时决定的，依赖于 java 虚拟机所在的操作系统的区域以及字符集。
在java.nio.charset包中的 Charset.java 中可以看到，默认字符集就是从 file.encoding 这个属性中获取的。
