Package: posh Version: 0.12.5 Severity: normal Dear Maintainer,
SUSv3 lists the prefix and postfix ++ and -- operators as "not required"[1] during arithmetic expansion and their use is not excepted from the requirements of Policy 10.4. In practice, using these operators would be a bad idea since they are not currently supported in dash (the postfix versions cause syntax errors while the prefix versions are silently ignored). An example of current behavior across shells is: $ FOO=1 bash -c 'echo $((FOO++)) $((++FOO))' 1 3 $ FOO=1 dash -c 'echo $((FOO++))' dash: 1: arithmetic expression: expecting primary: "FOO++" $ FOO=1 dash -c 'echo $((++FOO)) $((++FOO))' 1 1 $ FOO=1 posh -c 'echo $((FOO++)) $((++FOO))' 1 3 I would suggest removing support for these operators from posh so that shell scripts which rely on them can be identified and fixed. Thanks for considering, Kevin 1. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_06_04 -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (101, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.3.0+kevinoid1 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages posh depends on: ii debconf [debconf-2.0] 1.5.58 ii libc6 2.19-22 posh recommends no packages. posh suggests no packages. -- debconf information: posh/sh: false
