regex - regular expressions for selecting multiple lines -


i have text file in particular format..

!c_xyz|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|desc=xyz asdasda........................................................ asddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd !c_abc|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|desc=xyz...

i need regular expression reformat file using find , replace - visual studio. desc field value has overflowed onto next lines. need move them actual line. final string should 

    !c_xyz|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|desc=xyzsdasda.........asdddddd..     !c_abc|crby=112|crdate=12jun11|mdby=112|mddate=12jun11|desc=xyz...

i need re "desc=" followed until next ! symbol

find desc=([^\|\r\n]+)[\r\n](([^!\r\n][^\r\n]+[\r\n])*), replace desc=\1\2 , repeat until every line starts ! (you can test using ^[^!] search expr should find nothing).

alternatively find [\r\n]+, replace empty string. thereafter find !, replace \r\n!. suggestion has 2 drawbacks. temporarily produces long lines editor (notably vs) may or may not have difficulties , processes descriptions containing ! incorrectly.

addendum: input seems fixed format desc section. if indeed, can apply alternative #2, step 1, being followed search/replace run using (!.{53}\|desc=)/[\r\n]\1.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
