[patch] AddExpanderRuleToHaikuImage

[mmadia]

This patch creates a new rule AddExpanerRule, which allows optional packages to add one or more rules to common/etc/expander.rules

It is functional for the P7zip package and an upcoming XZ-Utils package. Tested in Haiku and FreeBSD.

common/etc/expander.rules:

"application/x-7z-compressed"	.7z	"7za l %s"	"7za x -y %s"
"application/x-xz"	.tar.xz	"xz -dc %s | tar tvf -"	"xz -dc %s | tar xvf -"
"application/x-xz"	.txz	"echo %s | sed 's/.xz$//g'"	"xz -df %s"

Is it AddExpanerRule on purpose? Or should it be AddExpanderRule? Just noticed, though I'd ask.

Heh... chalk that up to post-midnight coding. Luckily the typo is consistent throughout the patch.

[PieterPanman]

That's why I wondered, as you were so consistent, it must have been intentional ;)

For sake of consistency the rule should be named AddExpanderRuleToHaikuImage. Other than that, why not simply use another delimiter character instead of '|'? E.g. '#' comes to mind, or '!'.

The patch is updated. One thing that puzzles me, in hrev34942 echo -e ... was removed as the '-e' option isn't supported on FreeBSD. Despite this, action BuildHaikuImageExpanderRules seems to work without issue.

updated to use AddExpanderRuleToHaikuImage
