可以从命令行调用Excel函数吗？

我不想与任何文件进行任何交互.我只想像其他命令行工具一样使用这些函数.它应该仅用于一些一次性目的.

例如,如果有办法做这样的事情,我会喜欢它：

$excel roman(15)

XV

$excel randbetween(10,20)

14

当然,并非所有可用的功能都可以像这样运行,但越多越好.

提供这种选择？

>或者我们有什么方法可以操纵excel本身来做到这一点

(虽然根据我搜索的内容,这似乎不是

有可能)？

libformula可能是一个很好的起点.这是概念证明：

$excel 'TRIM(" abc 123 ")'

abc 123

excel就是这个简单的shell脚本：

#!/bin/sh

java -cp /usr/share/java/commons-logging.jar:libformula/demo:libbase/dist/libbase-6.1-SNAPSHOT.jar:libformula/dist/libformula-6.1-SNAPSHOT.jar:/home/cwarden/git/excel/src org.xerus.excel.Excel "$1"

和org.xerus.excel.Excel从argv获取一个字符串并将其作为公式计算：

package org.xerus.excel;

import org.pentaho.reporting.libraries.formula.EvaluationException;

import org.pentaho.reporting.libraries.formula.Formula;

import org.pentaho.reporting.libraries.formula.DefaultFormulaContext;

import org.pentaho.reporting.libraries.formula.parser.ParseException;

public class Excel {

public static void main(final String[] args) throws ParseException, EvaluationException {

final Formula f = new Formula(args[0]);

f.initialize(new DefaultFormulaContext());

final Object o = f.evaluate();

System.out.println(o);

}

}

libformula包含一个演示程序org.pentaho.reporting.libraries.formula.demo.PrintAllFunctions,它打印出所有支持的函数：
