Datestamps

pbb now adds dates to all the post titles on the index page and to the titles of individual posts. The date is simply extracted from the filename; in the md2html function, I check if the filename looks like it starts with a date, and if so, I add the date to the markdown:

{
    if [[ $file == ????-??-??-* ]]; then
        printf '%s\n\n' "${file:0:10}"
    fi
    cat "$file"
} | pandoc "${args[@]}"

where ${file:0:10} is a parameter expansion that extracts the first ten characters from the filename and args is an array containing all the pandoc options I need.

pbb now clocks in at 157 lines and is still quite readable (at least for me, shortly after writing it); I’m thinking about adding Bats tests soon to make it easier to see if something breaks when I add new features.
