Hello
As on my blog I use different markup languages I would like to use a simpler
markup language not requiring an extra package. To do so, I wrote an awk
script handling titles, paragraphs and code blocks the same way markdown does.
Code below contain the addition.
It is very easy to use, like: `awk -f mmd file.mmd > output.html`
The script is the following:
BEGIN {
in_code=0
in_list_unordered=0
in_list_ordered=0
in_paragraph=0
}
{
# escape < > characters
gsub(/</,"\<",$0);
gsub(/>/,"\>",$0);
# close code blocks
if(! match($0,/^ /)) {
if(in_code) {
in_code=0
printf "</code></pre>\n"
}
}
# close unordered list
if(! match($0,/^- /)) {
if(in_list_unordered) {
in_list_unordered=0
printf "</ul>\n"
}
}
# close ordered list
if(! match($0,/^[0-9]+\. /)) {
if(in_list_ordered) {
in_list_ordered=0
printf "</ol>\n"
}
}
# display titles
if(match($0,/^#/)) {
if(match($0,/^(#+)/)) {
printf "<h%i>%s</h%i>\n", RLENGTH, substr($0,index($0,$2)), RLENGTH
}
# display code blocks
} else if(match($0,/^ /)) {
if(in_code==0) {
in_code=1
printf "<pre><code>"
print substr($0,5)
} else {
print substr($0,5)
}
# display unordered lists
} else if(match($0,/^- /)) {
if(in_list_unordered==0) {
in_list_unordered=1
printf "<ul>\n"
printf "<li>%s</li>\n", substr($0,3)
} else {
printf "<li>%s</li>\n", substr($0,3)
}
# display ordered lists
} else if(match($0,/^[0-9]+\. /)) {
n=index($0," ")+1
if(in_list_ordered==0) {
in_list_ordered=1
printf "<ol>\n"
printf "<li>%s</li>\n", substr($0,n)
} else {
printf "<li>%s</li>\n", substr($0,n)
}
# close p if current line is empty
} else {
if(length($0) == 0 && in_paragraph == 1 && in_code == 0) {
in_paragraph=0
printf "</p>"
} # we are still in a paragraph
if(length($0) != 0 && in_paragraph == 1) {
} # open a p tag if previous line is empty
if(length(previous_line)==0 && in_paragraph==0) {
in_paragraph=1
printf "<p>%s\n", $0
}
}
previous_line = $0
}
END {
if(in_code==1) {
printf "</code></pre>\n"
}
if(in_list_unordered==1) {
printf "</ul>\n"
}
if(in_list_ordered==1) {
printf "</ol>\n"
}
if(in_paragraph==1) {
printf "</p>\n"
}
}
