Anti Patterns Catalog

Posted by jpluimers on 2018/02/06

Recommended for any software developer or architect: browse [Archive.is] Anti Patterns Catalog and re-read it 6-12 months later, then contemplate if you have improved.

Summary:

This catalog lists AntiPatterns in two ways:

Removing double quotes from variables in batch file creates problems with CMD environment – Stack Overflow

Posted by jpluimers on 2018/02/06

Thanks [WayBack] Mr. Rick for the answer as this is exactly the bit I needed:

Input:

set widget="a very useful item"
set widget
set widget=%widget:"=%
set widget

Output:

widget="a very useful item"
widget=a very useful item

[WayBack] Removing double quotes from variables in batch file creates problems with CMD environment – Stack Overflow

This trick is convenient in cases like this:

set LocalHostsFile="%windir%\System32\drivers\etc\hosts"
set LocalHostsTemplate="%LocalHostsFile:"=%.template"

The above replaces ALL double quotes with nothing.

If you want to smart replace (like done when de-quoting CSV), you need a bit more complex code like described in [WayBack] batch file – Remove quotes from named environment variables in Windows scripts – Stack Overflow, where you basically have two options:

  • assigning inside a for loop
  • assigning inside a subroutine

Both work because parameters used like %~x do get their quotes removed; you cannot use that syntax on plain variables.
