git - Escaping characters in Ruby Shell -

-

i have bash command:

git log --numstat --pretty="%h" -1 | awk 'nf==3 {plus+=$1; minus+=$2} end {printf("+%d, -%d\n", plus, minus)}'

i want assign command string variable , process output using exec(stringname) method.

the string command breaks @ "+%d, -%d\n". there way can escape these special characters?

if need quote has quotes in already, use %q method:

command = %q[git log --numstat --pretty="%h" -1 | awk 'nf==3 {plus+=$1; minus+=$2} end {printf("+%d, -%d\n", plus, minus)}']

doing of in ruby gives lot more control:

require 'open3'  open3.popen3('git', 'log', '--numstat', '--pretty="%h"', '-1') |stdin, stdout, stderr, wait_thr|   stdout.each_line |line|     if (line.match(/\a(\d+)\s+(\d+)\s+(.*)/))       puts '+%d, -%d' % [ $1, $2 ]     end   end end

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
