作为Windows/Mac/Linux下强大的文本编辑器,st提供了对Markdown语言的支持。通过设置可实现markdown预览和转换功能。而本文介绍的Markdown
Preview
支持Mathjax语法和目录自动生成。(Windows下)
安装Package Control
安装包控制扩展可以方便地为st添加拓展。
打开st,按下组合键`Control + ``,出现控制台,输入
<code>import urllib2,os; pf='Package Control.sublime-package'; ipp = sublime.installed_packages_path(); os.makedirs( ipp ) if not os.path.exists(ipp) else None; urllib2.install_opener( urllib2.build_opener( urllib2.ProxyHandler( ))); open( os.path.join( ipp, pf), 'wb' ).write( urllib2.urlopen( 'http://sublime.wbond.net/' +pf.replace( ' ','%20' )).read()); print( 'Please restart Sublime Text to finish installation')</code>
当看到代码最后一行提示的时候说明安装成功,此时重启st,可在Preferences -> Package Settings
看到Package
Control
。
安装markdown preview
按下键Ctrl+Shift+p
调出命令面板,找到Package
Control: install Pakage
这一项。搜索markdown preview,点击安装。
使用
Markdown Preview较常用的功能是preview in browser
和Export
HTML in Sublime Text
,前者可以在浏览器看到预览效果,后者可将markdown保存为html文件。
preview in browser
据称是实时的,但是实践上还是需要在st保存,然后浏览器刷新才能看到新的效果,好在markdown写得多的话也不需要每敲一行看一次效果。
快捷键
st支持自定义快捷键,markdown preview
默认没有快捷键,我们可以自己为preview
in browser
设置快捷键。方法是在Preferences -> Key Bindings User
打开的文件的中括号中添加以下代码(可在Key
Bindings Default找到格式):
<code> { "keys": ["alt+m"], "command": "markdown_preview", "args": { "target": "browser"} }</code>
"alt+m"可设置为自己喜欢的按键。
设置语法高亮和mathjax支持
在Preferences ->Package Settings->Markdown Preview->Setting Default
中的第31行和36行找到
<code>/* Enable or not mathjax support. */ "enable_mathjax": false, /* Enable or not highlight.js support for syntax highlighting. */ "enable_highlight": false,</code>
将 两个false改为true即可。
语法高亮跟编辑器的主题有关,可以在Preferences ->Color Scheme
找自己喜欢的主题。
关于目录生成,只要文章是按照markdown语法写作的。在需要生成目录的地方写
<code>[TOC]</code>
即可。
如果你这里没有看到目录而只是看到代码,说明简书不支持目录自动生成哈哈
打印成pdf
将markdown转换为pdf应该有很多种方法的。我没有再折腾,直接用谷歌浏览器虚拟打印功能生成。
利用Markdown Preview
的Preview
in Browser
功能可以在浏览器上看到htm效果。在页面右键->打印->另存为pdf->调节页边距
即可将pdf文件下载下来。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
