unlang parsing

3 Feb 2009

      I have just come across an oddity in the unlang parsing. I though that I had some form of logic error, but it turned out to be
white space.

I had some unlang code, like the following:
---
                 if (condition) {
                         update control {
                                 Attrib1 := "value1"
                         }
                 } else {
                         update control {
                                 Attrib2 := "value2"
                         }
                 }
---

Starting FreeRADIUS in debug gave me the error:
---
/etc/freeradius/sites-enabled/radius3[91]: Too many closing braces
Errors reading /etc/freeradius/radiusd.conf
---

Restructuring the code the to following, however, works fine.
---
                 if (condition) {
                         update control {
                                 Attrib1 := "value1"
                         }
                 }
                 else {
                         update control {
                                 Attrib2 := "value2"
                         }
                 }
---

The difference is just the newline after the closing 'if' brace.
I had a look for this being mentioned in the man page but did not see anything, except my previous micro-patch.

If this known and/or documented?
