Hi,
I have a rhtml file that uses some ruby code inside,
there are not too ruby codes, but it repeats itself
thousands of time. I find out each time when the ruby
code execute, it will produce the html code correctly.
But the produced html will conseved the "format" of
the rhtml, and it adds a lot no used white space!!!!
example : toto.rhtml
<body>
<table>
<% data.each{ |x| %>
<% y = x.methode1 %>
<tr><td><%= y %></td><tr>
<% z = x.methode2 %>
<tr><td><%= z %></td><tr>
</table>
</body>
So if data has 3000 rolls, I will have a html like
this:
<body>
<table>
<tr><td>y1</td><tr>
<tr><td>z1</td><tr>
<tr><td>y2</td><tr>
<tr><td>z2</td><tr>
<tr><td>y3</td><tr>
<tr><td>z3</td><tr>
.....
</table>
</body>
I have a lot of white space and each white space is
8byte, so my html file has almost 6meg instead of 2.5
meg (without white space)
Can someone know how shoulf I remove all the white
space????
Thanks you very much
Saiho

Hey, in your <% %> tags end them with -%> and that''ll supress the extra carriage return.

That makes the processor consume the following newline, which should make things a little easier. Also, you can join successive <% %> blocks together - you don''t need a separate tag for each line. I''d write your block above as follows: <body> <table> <% data.each do |x| y = x.methode1 z = x.methode2 -%> <tr><td><%= y %></td><tr> <tr><td><%= z %></td><tr> <% end -%> </table> </body> Or possibly, simpler: <body> <table> <% data.each do |x| -%> <tr><td><%= x.methode1 %></td><tr> <tr><td><%= x.methode2 %></td><tr> <% end -%> </table> </body> -- Alex
Hi, Thanks you very much for the information the -%> works great with the end of a line, but is there something that I can remove the white space at the begining of the line, bacause if the ruby code it placed after 3 tab ( for code visibility) the html will also have 3 tab added. it is possible to remove that also? Thanks again for all the information!!!

If you want to nicely format up the html (so you can better see what''s going on) might I suggest using Tidy and running the output through that? Works well!

You''d probably want to do something more along the lines of .gsub(/\s+/, '' '') so that individual spaces don''t get clobbered. I''ve got no idea how long it''ll take on a 3+MB string, though... -- Alex

Aren''t consecutive space characters treated as a single space by HTML renderers? Or is that info hopelessly outdated? -- Alex
Ezra Zygmuntowicz <ezmobius@...> writes:> Don''t do this! It will also remove spaces in your text that you want > to show up on the page.There is no such thing. HTML clobbers spaces anyway, so runs of more than one consecutive spaces will be show as a single space.
