This is to see of code/pre tags work in Midnight Pub posts.

So here are the two pieces of code whose high-level description (when combined) transforms text into Mignight Pub friendly text/tags (huh... but I see I used two Lua scripts - not one Lua and one bash as first reported);

The "y1" script:

<pre><code>#! /usr/bin/env lua local lines = {} for line in io.stdin:lines() do table.insert(lines, line) end local url = '' if arg[1] then url = ' ' .. arg[1] end local handle = io.popen('fmt -60 | quote-br' .. url, 'w') handle:write(table.concat(lines, ' ')) handle:close() local num_url_spaces = 30 if arg[1] then io.stdout:write('> >') for i=1,num_url_spaces do io.stdout:write(' ') end print('- ' .. arg[1]) end </code></pre>

The "quote-br" script called by the "y1" script:

<pre><code>#! /usr/bin/env lua local lines = {} for line in io.stdin:lines() do table.insert(lines, '> ' .. line .. ' ') end io.stdout:write(table.concat(lines, '')) </code></pre>

Okay, trying it one more time, this time with a bit more attention to lines beginning with whitespace:

y1:

<pre><code>#! /usr/bin/env lua local lines = {} for line in io.stdin:lines() do   table.insert(lines, line) end local url = '' if arg[1] then   url = ' ' .. arg[1] end local handle = io.popen('fmt -60 | quote-br' .. url, 'w') handle:write(table.concat(lines, ' ')) handle:close() local num_url_spaces = 30 if arg[1] then   io.stdout:write('> >')   for i=1,num_url_spaces do     io.stdout:write(' ')   end   print('- ' .. arg[1]) end </code></pre>

quote-br:

<pre><code>#! /usr/bin/env lua local lines = {} for line in io.stdin:lines() do   if arg[1] then     local whitespace,rest = string.match(line, '^(%s+)(.*) )     if whitespace then       whitespace = string.gsub(whitespace, ' ', '  ')       whitespace = string.gsub(whitespace, '\t', '  ')       if rest then         rest = string.gsub(rest, '<', '<')         rest = string.gsub(rest, '>', '>')       else         rest = ''       end       line = whitespace .. rest     end   end   if arg[1] then     table.insert(lines, line .. ' ')   else     table.insert(lines, '> ' .. line .. ' ')   end end io.stdout:write(table.concat(lines, '')) </code></pre>

Hmmm.

So I needed to add tags to the end of all the code lines, then much all the code lines into a single line to make it work. Not too convenient.

And then I'd need to go a step further and convert tab characters (which I prefer for indentation) to good 'ole "nbsp" entities....
