In Vim, when entering a new tab, how to ignore BufEnter event? -


i have autocmds run vimscript function. function bound tabenter , bufenter.

however when enters new tab, function run several times because both autocmds fire (and tabenter seems fire bufenter previous "current" buffer before firing again new buffer...i think).

anyway, how can run function once when enters new tab?

you didn't tell when functionality needs triggered; maybe combination of events (tabenter , bufenter unrelated; if same buffer displayed in both tabs?) off, , problem fixed choosing other events.

apart that, could:

  • store last processed buffer (bufnr('')) / window (winnr()) / ... in script-local variable, , short-circuit function if it's same
  • if problem long delay in function, store timestamp (localtime()) , short-circuit when little time passed
  • if have tab-switching under control (but don't), :noautocmd , :set eventigore+=... remedy this

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 ...
