Any update?

Am I missing something?

The change that chrox mentioned should be alone sufficient to archieve what you want to do. Note that the expressions will only match lower case file extensions. No other changes should be applied in addition.

That said, I won't have time to look into this for about another week, I guess. Maybe someone else can have a look.

but I just want to view the 'pdf' documents with koreader.

You don't have to edit filechooser.lua. In koreader there already is an implementation for choosing what extensions to use.

In koreader/frontend/document your will find three scripts:
pdfdocument.lua for pdf-files,
djvudocument.lua for dvju-files,
credocument.lua for all other handled files.

At the end of each file you have lines such as:
DocumentRegistry:addProvider("txt", "application/txt", CreDocument)

Comment out those extensions you do not want to see by prefixing "--" or add lines for new extensions, e.g.:
DocumentRegistry:addProvider("lua", "application/txt", CreDocument)

In the case of showing only pdf- and epub-files comment out the DocumentRegistry in dvjudocument.lua and all lines but one in credocument.lua.

Thanks. This does work though partially for me. It shows all the directories but only those directories which have pdf, ePUB or djvu files show the filenames. Rest of the directories do not have any entries. Ideally, I would like to get a list of only those directories which have pdf, ePUB or djvu files so as to not clutter the file manager display with empty directories. Maybe its too much to ask.

That's indeed much more complicated - Koreader does (currently) take the file manager approach, directory-wise, so it does not look into subdirectories. What you ask for would probably be calling for a database approach - possible, but the foundations are not there yet.

Thanks for the update. For the time being I will stick with the solution given by Thomass by storing all the pdf, ePUB and djvu files in the documents directory. Somehow I prefer an uncluttered file manager menu in KOReader displaying just the relevant files. Hopefully in the future versions fo KOReader this feature gets implemented

Is there any place where I can view the changelog for the nightlies? That way one can decide whether to install the nightly build. Searched for the changelogs but could not find them.

you can follow the closed issues and here the upcoming ones.

I have installed the stardict dictionaries and the Tesseract OCR package. The dictionary works perfectly with pdf and djvu documents but not with ePUB books. Do I need to something differently or it is not supposed to work with ePUB books.

BTW, the scrolling for dictionary definitions works perfectly with today's nightly. Thanks!

It's in the list of unsolved issues already.

(crereader is used for all of the supported document types except pdf and djvu.)

Here both xps and cbz stated as supported formats though didn't try them myself.
