Hi all,
Is there no way to easily resolve this. It can''t be that I''m
the first that
wants this, and it wouldn''t be RoR if it''s not possible.
On the mysql prompt with the select description from todos .. linefeeds are
show, so they are there.
This is the actual contents with a linefeed after the ":"
"Project contacts:
delete table, point project to contacts"
But this: <%= todo.description.tr(''\n'', ''<br
/>'') %>
Results in this:
Project co
(It actually replaces "n",and it''s on to the next cell)
And with double quotes int the statement it''s this:
"Project contacts:"
(and it''s on to the next cell).
Tried RedCloth but that doesn''t work as simple either (not at all
actually,
because it doesn''t know textilize or textile as a methgod after
install)
Help is greately appreciated.
Regards,
Gerard.

Hi Gerard,
regarding RedCloth: sounds as if you didn''t make rails to know about
RedCloth. Is
require ''rubygems''
require_gem ''RedCloth''
in your environment.rb?
whats .tr about (don''t know this method). You might have a try with
todo.description.gsub(''\n'', ''<br />'')
Best Regards

Jan, Found it after chewing on your input. This one does the trick. gsub should be written with slashes: <%= todo.description.gsub(/\n/, ''<br />'') %>< What still confuses me though is that redcloth is not available:> require ''rubygems'' > require_gem ''RedCloth''I put these in and restarted webrick. WIth the result: undefined method `textile'' for "Project contacts:\ndelete table, point project to contacts":String (textilize doesn''t work either)> whats .tr about (don''t know this method). You might have a try with > todo.description.gsub(''\n'', ''<br />'')I''ve seen the "tr" come by somewhere in this list and is mentioned on the ruby book: http://www.ruby-doc.org/docs/ProgrammingRuby/ Under: http://www.ruby-doc.org/docs/ProgrammingRuby/html/ref_c_string.html#String.tr Thanx a lot!

String#tr is for translating single characters to other single characters. You can''t replace a single character with more than one characer using tr. Use String#gsub instead. todo.description.gsub( "\n", "<br />" ) On 1/17/06, Gerard Petersen <mailing@gp-net.nl> wrote:> Hi all, > > Is there no way to easily resolve this.

What you really needed was gsub("\n", ''<br />'') instead, which gives you the correct result. - Matt
I figured I would just add that you may want to use the "simple_format" function - it doesn''t just do \n to <br /> but a few other things and wraps in a <p> tag - not always desirable but since you were considering using Textile I figured it was worth mentioning. Docs on simple_format are here: http://api.rubyonrails.com/classes/ActionView/Helpers/TextHelper.html#M000425 If you take a look at the source it shows you''ll see it''s some regexs, nothing fancy, but nevertheless useful.

Looks nice TNX!

I''ll hack on that thanks! So those win cr/lf''s would contain two chars then when in between doubles?

"\n" is a single character String object, containing the newline character ASCII code 0x0A. (On windows, "\n" *may* expand to the two-character String object 0x0D 0x0A under some circumstances, but I''ve got no experience with Ruby on windows, so if you''re on windows you''re on your own). - Matt
