宏的概念
什么是宏呢?英文名:macro,代表一串命令的集合。
示例操作文本
SELECT * FROM `edu_ocr_task` WHERE ((`userId`=284871) AND (`userType`=3)) AND (`status` >= 0) AND (`correctCnt` > 0) ORDER BY `addTime` DESC LIMIT 16 OFFSET 30;
SELECT `imgId`, `taskId`, `imgUrl`, `status`, `ocrResult`, `feedback`, `totalQuestionCount`, `correctQuestionCount`, `finalOcrResult`, `addTime`, `completeTime`, `updateTime` FROM `edu_ocr_img` WHERE (`taskId` IN ('143736', '143725', '143723', '143722', '143715', '143682', '143681', '143677', '143676', '143651')) AND (`status` > 0);
SELECT sum(correctCnt) FROM `edu_ocr_task` WHERE ((`userId`=284871) AND (`userType`=3)) AND (`status` >= 0);
UPDATE `edu_ocr_task` SET `status`=-2 WHERE (`userId`=11580815) AND (`status` IN (1, 0)) AND (`userType`=1) AND (`taskId`=224876);
UPDATE `edu_ocr_task` SET `status`=-2 WHERE (`userId`=11580815) AND (`status` IN (1, 0)) AND (`userType`=1);

号宏
.
号是英文中的句号.
需要在普通模式中执行.
执行效果为: 重复执行一次上次的修改
(关于修改的定义不做详细解析).
命令序列: cwaaa j.
结果:
(注意 aaa 的位置)
aaa * FROM `edu_ocr_task` WHERE ((`userId`=284871) AND (`userType`=3)) AND (`status` >= 0) AND (`correctCnt` > 0) ORDER BY `addTime` DESC LIMIT 16 OFFSET 30;
SEaaa `imgId`, `taskId`, `imgUrl`, `status`, `ocrResult`, `feedback`, `totalQuestionCount`, `correctQuestionCount`, `finalOcrResult`, `addTime`, `completeTime`, `updateTime` FROM `edu_ocr_img` WHERE (`taskId` IN ('143736', '143725', '143723', '143722', '143715', '143682', '143681', '143677', '143676', '143651')) AND (`status` > 0);
SELECT sum(correctCnt) FROM `edu_ocr_task` WHERE ((`userId`=284871) AND (`userType`=3)) AND (`status` >= 0);
UPDATE `edu_ocr_task` SET `status`=-2 WHERE (`userId`=11580815) AND (`status` IN (1, 0)) AND (`userType`=1) AND (`taskId`=224876);
UPDATE `edu_ocr_task` SET `status`=-2 WHERE (`userId`=11580815) AND (`status` IN (1, 0)) AND (`userType`=1);
录制宏
q
键既是录制的开始, 也是录制的结束按键. 录制过程中会显示recording @{字母}
示例按键: qqdwjq@q@@@@
将每一行的第一个单词删除:
* FROM `edu_ocr_task` WHERE ((`userId`=284871) AND (`userType`=3)) AND (`status` >= 0) AND (`correctCnt` > 0) ORDER BY `addTime` DESC LIMIT 16 OFFSET 30;
`imgId`, `taskId`, `imgUrl`, `status`, `ocrResult`, `feedback`, `totalQuestionCount`, `correctQuestionCount`, `finalOcrResult`, `addTime`, `completeTime`, `updateTime` FROM `edu_ocr_img` WHERE (`taskId` IN ('143736', '143725', '143723', '143722', '143715', '143682', '143681', '143677', '143676', '143651')) AND (`status` > 0);
sum(correctCnt) FROM `edu_ocr_task` WHERE ((`userId`=284871) AND (`userType`=3)) AND (`status` >= 0);
`edu_ocr_task` SET `status`=-2 WHERE (`userId`=11580815) AND (`status` IN (1, 0)) AND (`userType`=1) AND (`taskId`=224876);
`edu_ocr_task` SET `status`=-2 WHERE (`userId`=11580815) AND (`status` IN (1, 0)) AND (`userType`=1);
示例讲解
qq
: q
开启录制宏, 选择 q
这个寄存器放置宏的内容
dwjq
: 删除第一个单词, 并且光标下移一行, q
结束录制
@q
: 回放存放在 q
寄存器里面的命令
@@
: 回放上一次执行的宏
这样一个简单的宏就完成了.
查看宏的内容
:reg q
会显示如下内容:
:reg q
--- Registers ---
"q dwj
修改宏
在录制过程中, 难免会录制错误. 那么如何修改你已经录制好的宏呢?
在宏的尾部增加命令
qQ
这回将你之后输入的序列追加到 q
寄存器中, 而不是重新覆盖.
重新编辑宏指令
- :tabn | 重新打开一个 tab
- :put q | 将
q
寄存器里面的内容复制到当前文件中 - 编辑你的宏命令 (在编辑之前有必要先去学习一下
宏中的键盘编码
) - :d q | 将当前行删除, 并且放到
q
寄存器中 - @q | 执行
q
寄存器中的指令
