Comments on: Right-Aligned Snippet Placeholders

As I didn't understand very well the ruby+regexp+snippets solution, I decided to try to get the same result with a (hopefully simpler) Python-only command:

#!/usr/bin/env python
from sys import stdin

width = 20
s = stdin.read()

print "-" * width
print s.rjust(width)
print "-" * width

Anyone have a PHP or CSS translation of this?

Some alternatives for the ugly 1.upto(width):

print (1..width).map { |i| "(?#{i}:: )" }

width.times { |i| print "(?#{i+1}:: )" }

i = 0
width.times { print "(?#{i+=1}:: )" }

But the whole thing is just too complicated...I would prefer putting Ruby code into the ${...} expressions...like

${ruby:width=[30, $1.size].max}
# ${ruby:'-' * width}
# ${ruby:' ' * (width - $1.size)}${1:Header}
# ${ruby:'-' * width}

and

${ruby:width=[30, $1.size].max}
/*${ruby:'*' * width}*
* ${ruby:' ' * (width - $1.size)}${1:Header}*
**${ruby:'-' * width}*/

for C-style comments.

#!/usr/bin/env ruby

width = 30

print "/", "*"*width, "\n"
print "${1/^", "(.)?"*width, ".*$/*"
1.upto(width) { |i| print "(?#{i}:: )" }
print "/}${1:Header}\n"
print "*"*width, "/\n"

I'm confused as to why the example given doesn't output the line above and below the the comment, this version I've done does. Bearing in mind I've never actually programmed Ruby before it might not be the most efficient way to do it.

#!/usr/bin/env ruby

width = 30

print "/"
width.times { print "*" }
print "\n"
print "${1/^" + "(.)?"*width + ".*$/"
print "*"
1.upto(width) { |i| print "(?#{i}:: )" }
print "/}${1:Header}" + "\n"
width.times { print "*" }
print "/\n"

Ben: Yeah, my “script” was meant as a subset of a full snippet-generating script, so I didn’t put any shebang in it.

Simon: I fixed it — if you (or anyone else) know of a preview plug-in for WordPress which works with the Markdown plug-in and is a hassle-free install, let me know — for now there is Edit in TM and Preview from there :)

Thanks for cleaning up, whoever it was. ;-)

Bah – formatting didn't work. This blog needs preview mode!

In Python:

#!/usr/bin/env python
width=20
print ''.join('(?%s:: )' % i for i in range(1, width+1))

not sure if anyone else had this problem, but i had to add:

#!/usr/bin/env ruby

to the top of the command. Otherwise I just keep getting errors.
