javascript - Source code lost. Minified file available. How to unminify the file. -


i have javascript file in minified version. have lost original source code. how can recover source code minified version? variable names appearing _1, _2 etc. there way through can change variable names meaningful.

minification must have minified script, if variable names have been changed means used kind of uglifier. there several online tools available http://jsbeautifier.org/ that'd unminify code, uglification can not undone, you've rename variables manually.

protip: use version control system git keep revisions/history , take backups don't loose source code in future.

i understand strange issues occur, hope resolve them. luck!

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 ...
