Extract and Use System Output (Batch) -


i write batch file allows quicker assembling of multiple assembly files using a86 assembler , view result. there 2 cases, when there assembly error , when there no error.

sample assembler input:

a86 file1.asm file2.asm file3.asm file4.asm

case 1: error. supposing there error in file3.asm, system output on line 4:

error messages inserted file3.asm

case 2: no error. system output on line 4:

object: file1.bin

in case 1, open file generated error using notepad++, using command notepad++ filename.asm.

in case 2, open generated object in hex editor using command hxd filename.bin.

what can done extract error/success file name system output?

sorry, i'm not familiar a86, have idea or two. if a86 returns 0 on success, non-zero on fail, way:

@echo off setlocal enabledelayedexpansion  if defined programfiles(x86) (set "pf=%programfiles(x86)%") else set "pf=%programfiles%"  :: path notepad++ set "npp=%pf%\notepad++\notepad++.exe"  :: path hxd (fix this, please) set "hxd=%pf%\hxd\hxd.exe"  set idx=1  /f "tokens=1-5*" %%a in (     'a86 file1.asm file2.asm file3.asm file4.asm 2^>^&1' ) (     if !idx! equ 4 (         rem if %errorlevel% non-zero (is 1 or higher)         if errrorlevel 1 (             start "" "%npp%" %%e         ) else (             start "" "%hxd%" %%b         )     )     echo(%%a %%b %%c %%d %%e %%f     set /a "idx+=1" )

if errorlevel returned a86 not reliable indicator, change if errorlevel 1 if "%%j"==""

you didn't mention whether error output of a86 sent via stderr or stdout, redirected stderr stdout in for loop 2^>^&1. have no clue whether it's needed or not, shouldn't hurt if not.

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 ...
