## Test extract operation.
# XFAIL: system-darwin

# RUN: rm -rf %t && mkdir -p %t/extracted/

## Extracting from an empty archive should not warn or error:
# RUN: llvm-ar cr --format=gnu %t/empty.a
# RUN: llvm-ar xv %t/empty.a 2>&1 | count 0

# RUN: echo filea > %t/a.txt
# RUN: echo fileb > %t/b.txt
# RUN: llvm-ar rc %t/archive.a %t/a.txt %t/b.txt

## Single member:
# RUN: cd %t/extracted && llvm-ar xv %t/archive.a a.txt | FileCheck %s --check-prefix=A
# RUN: diff %t/a.txt %t/extracted/a.txt
# A: x - a.txt

## All members:
# RUN: rm %t/extracted/a.txt
# RUN: cd %t/extracted && llvm-ar xv %t/archive.a | FileCheck %s --check-prefix=AB
# RUN: diff %t/a.txt %t/extracted/a.txt
# RUN: diff %t/b.txt %t/extracted/b.txt
# AB: x - a.txt
# AB: x - b.txt

## Thin archive 
# RUN: llvm-ar Trc %t/thin-archive.a
# RUN: not llvm-ar x %t/thin-archive.a 2>&1 | FileCheck %s --check-prefix=THIN
# THIN: extracting from a thin archive is not supported

## No output if 'v' is not specified.
# RUN: rm a.txt b.txt
# RUN: llvm-ar x %t/archive.a 2>&1 | count 0
# RUN: diff %t/a.txt %t/extracted/a.txt
# RUN: diff %t/b.txt %t/extracted/b.txt

## --output specifies the directory to extract archive members to. `1/2` is created by llvm-ar.
# RUN: llvm-ar --output=1/2 x %t/archive.a
# RUN: diff %t/a.txt %t/extracted/1/2/a.txt
# RUN: diff %t/b.txt %t/extracted/1/2/b.txt

## --output can be used with an absolute path and can be specified elsewhere on the command line.
# RUN: rm 1/2/a.txt
# RUN: llvm-ar xv %t/archive.a a.txt --output %t/extracted/1/2/../2 | FileCheck %s --check-prefix=OUTPUT-A
# RUN: diff %t/a.txt %t/extracted/1/2/a.txt
# OUTPUT-A: x - {{.*}}extracted{{.*}}a.txt

# RUN: not llvm-ar x --output=%t/a.txt %t/archive.a 2>&1 | FileCheck %s --check-prefix=OUTPUT-NOTDIR
# RUN: not llvm-ar x --output=%t/b.txt/a.txt %t/archive.a 2>&1 | FileCheck %s --check-prefix=OUTPUT-NOTDIR
# OUTPUT-NOTDIR: error: '{{.*}}a.txt' is not a directory

# RUN: not llvm-ar rc --output=1/2 %t/archive.a %t/a.txt 2>&1 | FileCheck %s --check-prefix=OUTPUT-ERR
# OUTPUT-ERR: error: --output is only applicable to the 'x' operation
