pattern matching - Detect and match function opening and end brace in source code -


i know if there algorithms detect function declaration, function content, opening brace , closing one. development, debug , testing bugs, nice in cases need add lot of code in functions.

example source code:

test.onload=function(event){     test.initialize(); };

result:

  • function name: test.onload
  • content: test.initialize();
  • opening brace found @ line: 1.
  • closing brace found @ line 3.

we example, information above, add line @ beginning of functions , @ end of them, log parameters:

test.onload=function(event){     log("loginit","function:test.onload","openbraceline:1","content: test.initialize();");     test.initialize();     log("logend ","function:test.onload","endbraceline :5","content: test.initialize();"); };

i know functionality made simple global log , call stack, there still lot of examples usefull.


making simple algorithm detect , match braces , function information easy there lot of exceptions complicated, , thats why im asking if there known ways of detecting it.
i dont mind if examples algorithms or tips in language, wanted see best ways of doing it.

notepad++ example because has plugin detects lot of different source code languages , parses code colors each part , matches braces.

using real parser solution work in cases.

this seems javascript, suggestion use rhino, easy use, tool java tool in end, of course.

if solution needs in javascript, too, can take @ this question parsers in javascript

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
