javascript - wysihtml5 - how disable underline tag -


i have small problem wysihtml5 on site. want allow few html tags , if remove underline parser rules , underline command wysihtml5 library, can still press ctrl(command)+u make selected text underlined. should rid of behaviour? advices.

new answer: here updated solution. updated existing keydown event handler (and added keyup handler tracking ctrl pressed state) follows:

// --------- shortcut logic --------- var ctrldown = 0;  dom.observe(element, "keydown", function(event) {   var keycode  = event ? event.which : window.event.keycode,     command    = shortcuts[keycode];   if (1 == event.ctrlkey) {     console.log('ctrl key pressed. setting ctrldown = 1.');     ctrldown = 1;   }   if (85 == keycode && 1 == ctrldown) {     console.log('pressed "u" (keycode 85), ctrl key still down. don\'t fire!');     return event.preventdefault(), !1;   }   if (1 == ctrldown && !event.altkey && command) {     console.log('shortcut ctrl + keycode ' + keycode + ' triggered.');     that.commands.exec(command), event.preventdefault();   } });  dom.observe(element, "keyup", function(event) {   // note: "event.ctrlkey" doesn't work keyup, use keycode/which    if (17 == (event ? event.which : window.event.keycode)) {     console.log('ctrl key released. setting ctrldown = 0.');     ctrldown = 0;   } });

i sent a pull request @ github.

original answer: needed do, disable ctrl+u keyboard shortcut, remove keycode "u" (85) shortcuts object @ line 8494 in wysihtml5-0.4.0pre.js.

change 

  shortcuts = {     "66": "bold",     // b     "73": "italic",   //     "85": "underline" // u   };

to 

  shortcuts = {     "66": "bold",     // b     "73": "italic"    //   };

and no longer able use ctrl+u shortcut within editor.

alternatively, catch keydown events , disable ctrl+u shortcut (ie. prevent default behaviour). like:

// --------- disable ctrl+u shortcut underlining texts --------- dom.observe(element, "keydown", function(event) {   if ((event.ctrlkey || event.metakey) && 'u' == string.fromcharcode(event.which).tolowercase()) {     //   }        });

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 ...
