Javascript code to count occurrences of words inside a list of pdf files. The long term goal is to make a Zotero (https://www.zotero.org/) plugin out of this code.
The program is launced via
npm start
The relevant input files are
files.txt, that contains a list of relative paths to pdf files.words.txt, that contains the list of the words we want to count. In both files, entries are separated by a newline.
The output is generated in output.csv. It is a standard csv file. Each row represents a pdf file, each column is a word we want to count. Entries are the number of appearences of the given word in the given document.
In order to search a pdf, the library pdf-parse (https://www.npmjs.com/package/pdf-parse) was installed.
