source: trunk/launch/launch/main.c@ 176

Last change on this file since 176 was 166, checked in by Nicholas Riley, 19 years ago

VERSION: Updated for 1.0.1.

main.c: Updated copyright statement. Updated for 1.0.1. Added -U,
triggers OPTS.forceURLs. Added kLSMultipleSessionsNotSupportedErr,
nsvErr. Cleaned up string encoding handling; works much better now.
Split code into stringFromURLIsRemote, utf8StringFromCFStringRef, and
utf8StringFromOSType. Display "contents: zero items" instead of "0
items" in printMoreInfoForURL. Remove extraneous "./" at beginning of
displayed paths. Get versions of non-{applications, packages} and
info from nonbundled apps with CFBundleCopyInfoDictionaryForURL.
Replaced some error codes with numbers so we support building on 10.2
again.

launch.1: Updated for 1.0.1 and -U option.

README: Updated for 1.0.1. Fixed a paste-o in the uninstallation
instructions.

package-launch.sh: Use zsh explicitly. Build as deployment. Fix
permissions. Make tarball contents owned by root/wheel.

18/* To do/think about:
19
20- Launching as root: use authentication framework - doesn't work.
21
22- launch URL with specified URL handler (done, except for IC)
23
24- launch apps by IC protocol handler (esp. editor)
25
26Thanks to:

28- Nat Irons, for encouragement and suggestions

30- Brian Hill, for the great Security.framework tutorial and sample code
