# * If ocr (tesseract rule) has been performed do repeate it
# * document depencies
# * remove tmp files

##### ADMINISTRATIVE RECIPES

dirs: # create the directories for the working structures
	@mkdir -p images # scanned image dir
	@mkdir -p output # outputs dir
	@echo $(color_r)'Directories made'

rmtmp:
	rm $(tmpfile)

testif:
ifeq ($(OS),Darwin)
	@echo $(OS)
endif


##### POST-PROCESSING RECIPES

tesseract:
	echo $(listimgs) > ocr/list.txt
	tesseract ocr/list.txt $(basename $(output_ocr))


##### OUTPUT GENERATION RECIPES

	cat $(output_ocr) | python3 src/myscript.py > output/a-new-file.txt

wordtagger: tesseract
	cat $(output_ocr) | python3 src/wordtagger.py > output/tagged-words.txt
# DEPENDENCY: nltk, nltk: 'averaged_perceptron_tagger'
#  $ python 3
#  >>> import nltk
#  >>> nltk.download('averaged_perceptron_tagger')

talktochatbot: tesseract
	cat $(output_ocr) | python3 src/textbotconversation.py
# depency: chatterbot 

n+7: tesseract
	cat $(output_ocr) | python3 src/n_7.py > output/n7.txt
