txt2lrf - New and Improved

[ns66]

Hi,

I need a simple utility to convert lots of txt or html files (some without extension even though they are txt or html) to lrf, or rtf, whatever format that can be easily read in sony reader, with no border, no need for special layout, just quick and batch, need to support unicode

I can code java very well, but I don't know anything about lrf or rtf format, if there's such module or code samples on that side that will help, I can easily build the rest.

or if your txt2lrf or html2lrf can handle (you can even merge them make it seemless) that's even better

thanks

I do suggest using html2lrf to convert your html files. Give them a go and see how it works. Might be just what you want.

As for the text files, use Word to format them and then import them into Book Designer after that. That's the easiest way to do it.

@DailyPlanet Yeah lit2lrf will be in the gui

@ns66 You're best bet is to write a script that runs through the files, detects if they are txt or html and call txt2lrf/html2lrf as appropriate.

I don't want to seem like a pest, but what is your estimated timeframe for releasing 4.0

Somewhere between 1 and 3 months

I have been having a problem with many txt files I try to run through this, where somewhere in the txt file is a unicode character the program cannot process.

I usually get a message like this:
UnicodeEncodeError: 'ascii' codec can't encode character u'\xc6' in position 25014: ordinal not in range(128)

which I guess is a python related error? (I know very little about programming)

I can sometimes track down the character if I can understand the unicode for that character, I use Charactermap to find and replace it in Word. But often with an error like this I don't know how to locate the character.

Does anyone have any tips for me on either a macro I can run in word to remove characters txt2lrf cannot process,or how to use the error message to locate the offending character?

Are there any plans to "pre-screen" text files in txt2lrf to help remove those characters?

So far I have been finding them manually by deleting half the text, seeing if the error remains, then keep deleting half until I find it. Which is super slow.

Any help would be appreciated!

You shouldn't be getting unicode errors. Can you post the full error message and the version of libprs500 you're using.

woops, double post

here is the error i get when trying to use txt2lrf on a gutenberg txt file from http://www.gutenberg.org/ebooks/7110


Traceback (most recent call last):
File "convert_from.py", line 89, in <module>

oh and I am using the latest version of the program, 0.3.79

[kovidgoyal]

Will be fixed in next release.

When running txt2lrf on the attached file,

alex@langabe:~/shared/ebooks-cache $ txt2lrf the\ art\ of\ war.txt

I get the runtime error specified in the subject line.

Python 2.5.1 (r251:54863, May 2 2007, 16:56:35)

alex@langabe:~/shared/ebooks-cache $ libprs500 --version
0.3.75

I don't think increasing the recursion limit will help, you'll run out of stack. It should probably implement the algorithm without recursion.

Nah this is probably a logic bug. Squashed in the next release. Also try upgrading to the latest version 0.3.79.

I'm using ver 103 and I am getting:

[kovidgoyal]

I cant duplicate this bug and the line numbers in the error message are wrong. Can you try uninstalling and re-installing libprs500.

Create a ticket and post the command line you used and also the text file.
