Re: [PATCH v4 4/5] env: Allow environment files to use the C preprocessor

Dear Simon,

In message 20210919125937.v4.4.Ie78bfbfca0d01d9cba501e127f446ec48e1f7afe@changeid you wrote:

+To add additional text to a variable you can use var+=value. This text is +merged into the variable during the make process and made available as a +single value to U-Boot.

Explained after use. Move documentation to previous patch?

• # Deal with +=
  

• if (match(var, "(.*)[+]$", var_arr)) {
  

• 	var = var_arr[1]
  

• 	env = vars[var] env
  

• }
  

Hm... this is (so far) a legal command:

=> setenv foobar+ foo+=bar

Best regards,
