Combine to single file for linux.

[shivanshu-semwal]

A much better option is to combine the python file into the shell script so we can put that one file in PATH,

#!/bin/bash

# Change to the directory of pdf file
cd $(dirname "$1")
pdf=$(basename "$1")
pdf_data="${pdf%.*}""_data.txt"
EXTRACT_FILE=booky_bookmarks_extract
bkFile="$2"


if [[ "$OSTYPE" == "darwin"* ]]; then
    SED=gsed
else
    SED=sed
fi

echo "Converting $bkFile to pdftk compatible format"
python3 -c '
import sys

level = 0
startChar = "{"
endChar = "}"
for line in sys.stdin:
	line = line.strip()
	if line == startChar:
		level = level + 1
	elif line == endChar:
		level = level - 1
	elif line:
		commaIndex = line.rfind(",")
		title = line[:commaIndex]
		pageNo = line[commaIndex + 1:].strip()
		print("BookmarkBegin")
		print("BookmarkTitle:", title.strip())
		print("BookmarkLevel:", level)
		print("BookmarkPageNumber:", pageNo.strip())' < "$bkFile" > "$EXTRACT_FILE"

echo "Dumping pdf meta data..."
pdftk "$pdf" dump_data_utf8 output "$pdf_data"

echo "Clear dumped data of any previous bookmarks"
$SED -i '/Bookmark/d' "$pdf_data"

echo "Inserting your bookmarks in the data"
$SED -i "/NumberOfPages/r $EXTRACT_FILE" "$pdf_data"

echo "Creating new pdf with your bookmarks..."
pdftk "$pdf" update_info_utf8 "$pdf_data" output "${pdf%.*}""_new.pdf"

echo "Deleting leftovers"
rm "$EXTRACT_FILE" "$pdf_data"
