js-ppt's Introduction

ppt

Parser and writer for PowerPoint PPT files. Pure-JS cleanroom implementation from the Microsoft Open Specifications and related documents.

Installation

In nodejs:

npm install ppt

CLI Tool

The node module ships with a binary ppt that dumps the text content of a PPT presentation. The only argument is the file name:

$ ppt test.ppt
...

Possible to expose method that returns string?

I see you are console.loging all the output. It would be nice if there was a way to call, for instance, readFile (or a new function) directly and get a string back and save the trouble of using a child process.

Does not parse image inside ppt/pptx

When parsing ppt/pptx file, how can we get images from a file?

Mistake in README.md

OS Windows 8.1
Instead of npm install ppt should be written npm install ppt -g because otherwise you will have error like. In other words it must be global module.

$ ppt
sh: ppt: command not found

Erroring out

I have a .ppt that's been sitting in the textract repo for a bit that I used for testing graceful error handling. In my case the error was textract does not currently extract files of type [[ application/vnd.ms-powerpoint ]]. Obviously that'll be changing.

https://github.com/dbashford/textract/blob/master/test/files/MxAgCrProd.ppt

This file throws up.

ppt MxAgCrProd.ppt 

/Users/dbashford/.nvm/v0.10.12/lib/node_modules/ppt/ppt.js:623
            if(persist) throw "unexpected second RT_PersistDirectoryAtom";
                        ^
unexpected second RT_PersistDirectoryAtom

Does not parse .pptx at all

                       ^

TypeError: ppt.find is not a function

Please update README.md with result of parsing
