emdfparse 1.0.3

emoney data file parser

# emdfparse

## 安装

```
python3 setup.py install # 需要安装python3, setuptools, 如果系统中有pip3, 说明setuptools已经有了
```

## 用途

解析DS几种落地文件(基于移动加强版Linux MDS, 猜测和金融平台使用的文件格式相同)

- K线类型: Day.dat, Day_\*.dat, Min1.dat, Min1_\*.dat, Min5.dat, Min5_\*.dat, Min30.dat, Min30_\*.dat 等
- 分时数据: Minute.dat_n 等
- 成交数据: Bargain.dat_n 等
- HisMin (我不知道怎么文字描述这个类型): HisMin.dat_n

可作为一个包供其他python脚本使用，也可以作为一个打印数据到标准输出的命令行工具使用

### 作为包

```
usage:

>>> from emdfparse import DataFile, Day
>>> df = DataFile('/usr/local/EMoney/Data/Day.dat', Day)
>>> for id, tms in df.items():
print('id: {}'.format(id))
print(tms)

id: 1

...
```


### 作为命令行工具

```
Usage:
emdfparse -h | --help | --version
emdfparse -t <type> (-c| -a| -l| -i <goodsid>) <filename>

Arguments:
filename name of data file

Options:
-h --help show help
-v --version show version
-t <type> specify the file type ( d| m| h| b ) d: Day, m: Minute, h: HisMin, b: Bargain
-c output goods number
-a output all goods time series data in file
-l list goods id in file
-i <goodsid> output the time data of specified good

```

示例:

#### 1. 列出Day.dat 股票数量
```
emdfparse -t d -c Day.dat

6718
```

#### 2. 列出Day.dat 中所有股票

```
emdfparse -t d -l Day.dat

1870213
1835501
1835502
1835503
...

后接 "|less" 可浏览, 接 "|wc -l" 可统计股票数量, 不赘述
```


#### 3. 列出HisMin.dat_1中goodsId为1的股票数据(最后先用1命令查看文件中是否有该goodsId, -i 指定文件中不存在的goodsId会抛KeyError异常)

```
emdfparse -t h -i 1 HisMin.dat_1|less
