# Steps:
|
||||
#
|
||||
# 1. Download corresponding html file for some README.md:
|
||||
# curl -s $1
|
||||
#
|
||||
# 2. Discard rows where no substring 'user-content-' (github's markup):
|
||||
# awk '/user-content-/ { ...
|
||||
#
|
||||
# 3.1 Get last number in each row like ' ... </span></a>sitemap.js</h1'.
|
||||
# It's a level of the current header:
|
||||
# substr($0, length($0), 1)
|
||||
#
|
||||
# 3.2 Get level from 3.1 and insert corresponding number of spaces before '*':
|
||||
# sprintf("%*s", (level-1)*'"$nb_spaces"', "")
|
||||
#
|
||||
# 4. Find head's text and insert it inside "* [ ... ]":
|
||||
# substr($0, match($0, /a>.*<\/h/)+2, RLENGTH-5)
|
||||
#
|
||||
# 5. Find anchor and insert it inside "(...)":
|
||||
# substr($0, match($0, "href=\"[^\"]+?\" ")+6, RLENGTH-8)

||||
