New Version of my Lit2PDF Script for Use/Review

dudeman41465 · 12-01-2010, 02:06 AM

You guys may have seen a couple of topics lately about a little script I've been maintaining personally. I posted a completed version of it a while back and just wanted to post the latest stable version. I'm using it as a pet project to teach myself proper BASH scripting, but also to help my wife get .lit e-books onto her Sony E-Reader since it seems to do a better job of converting the files than Calibre(For some reason some of our books won't convert in Calibre and they will with this). I've added some zenity windows to make it just a little more friendly in regards to selecting the file you want to convert. You no longer have to drag it into the terminal window and make sure you've got quotes around it if there's a space. It's also now completely BASH instead of python. I'm a "beginner" programmer/scripter, so some review, comments, and constructive criticism are welcome because everything I know I've taught myself with Google and experimentation.

To install it, just grab the tarball, extract it, make the files executable if they aren't already when you download them, and then run the install.sh file in the terminal. I tried to be very descriptive and informative in the changelog.txt and Readme.txt files as well so I hope those suit their purposes well.

P.S. If you're wondering about the versioning, I just adopted the same philosophy as the Ubuntu community and just made the date the version number. 10.11.30 equals November 30th, 2010.

Thanks for creating something. In return a wee code contrib FWIW:

Code:

#Lit2PDF 10.11.30
#This is a script to automate converting a .lit
#file to a .pdf file using convlit, html2ps, and ps2pdf
#software packages.
#Marcus Dean Adams (marcusdean.adams@gmail.com)

# Whoami
APPNAME="Lit2PDF"

# Ensure we actually have required apps and bail out:
for APPNAME in zenity clit html2ps ps2pdf mktemp; do
 which ${APPNAME} >/dev/null 2>&1 || exit 1
 done

# A Rolling Stone:
if [ -d "/home/${LOGNAME}" ]; then exit 1; fi

# Either ensure we create the temp dir in the users home or
# in another reasonable place:
if [ -d "/dev/shm" ]; then TEMPBASE="/dev/shm"
elif [ -d "/home/${LOGNAME}/tmp" ]; then TEMPBASE="/home/${LOGNAME}/tmp"
else TEMPBASE="/tmp"; fi

# Use 'mktemp' instead of creating temp directories:
export TMPDIR="${TEMPBASE}"
MYTMPDIR=`mktemp -p "${TEMPBASE}" -d ${APPNAME}.XXXXXXXXXX` && {
 zenity --info --TITLE="Lit2PDF" --text="Please select the file you wish to convert."
 INFILE=$(zenity --file-selection --filename=/home --TITLE="Select a LIT file")
 if [ $? == 0 ]; then
  TITLE=$(zenity --entry --text "What is the TITLE of the book?")
  if [ $? == 0 ]; then
   zenity --info --TITLE="Please wait..." --text="Conversion may take a long time depending on the length of the book.  Click OK to begin."
   clit "${INFILE}" "${MYTMPDIR}/html/"
   html2ps "${MYTMPDIR}/html/*.htm" > "${MYTMPDIR}/temp.ps"
   if [ -d "$HOME/Desktop" ]; then ps2pdf "${MYTMPDIR}/temp.ps" "${HOME}/Desktop/${TITLE:=untitled}.pdf"
    else ps2pdf "${MYTMPDIR}/temp.ps" "/tmp/${TITLE:=untitled}.pdf"
   fi
  fi
 fi
 rm -rf "${MYTMPDIR}"
 } # End Mktemp

# Make proper use of exit status:
exit 0
