Sir told me to make a script to create slides just by putting some images into a folder. Nice idea!
After trying some commands interactively, I wrapped the commands and first tried for manipulating text of a file. I got opportunity to use the sed (stream editor). Here is the script for that: Click here to see the script.
Here list contains the list of names of images that are to be replaced with the ‘variable()’ in the file ‘filename’.
Then I got the idea and created another script to add slides into the reveal-md presentation file.
Here is the link to script: addslide.sh
The lines I’ve echo’ed are the syntax to add a new slide in reveal-md presentation (three hyphens surrounded by new lines). Basically a new line is fetched from the file “list” (which contains the list of images in the images folder) and then it’s appended (due to ‘>>‘) in the file presentation.md by inserting the image names (from file ‘list’) within section tags (to change background).
After that I pushed the code to github.
