ax_at_check_pattern

Synopsis

AX_AT_CHECK_PATTERN(COMMANDS, [STATUS], [STDOUT-RE], [STDERR-RE], [RUN-IF-FAIL], [RUN-IF-PASS])
AX_AT_DIFF_PATTERN(PATTERN-FILE, TEST-FILE, [STATUS=0], [DIFFERENCES])

Description

AX_AT_CHECK_PATTERN() executes a test similar to AT_CHECK(), except that stdout and stderr are awk regular expressions (REs).

NOTE: as autoconf uses [] for quoting, the use of [brackets] in the RE arguments STDOUT-RE and STDERR-RE can be awkward and require careful extra quoting, or quadrigraphs ’@<:@’ (for ’[’) and ’@:>@’ (for ’]’).

awk is invoked via $AWK, which defaults to "awk" if unset or empty.

Implemented using AT_CHECK() with a custom value for $at_diff that invokes diff with an awk post-processor.

AX_AT_DIFF_PATTERN() checks that the PATTERN-FILE applies to TEST-FILE. If there are differences, STATUS will be 1 and they should be DIFFERENCES.
