source: releases/Pester/1.1b5/Source/NJRDateFormatter.m@ 517

Last change on this file since 517 was 361, checked in by Nicholas Riley, 17 years ago

VERSION: Updated for 1.1b5.

English.lproj/InfoPlist.strings: Updated for 1.1b5.

English.lproj/MainMenu.nib: Change IB compatibility level to 10.4.
Disable controls which lead to unstable functionality in this version.
Added Sparkle support. Hook up removeMessageButton to
PSAlarmSetController for "-" fallback drawing.

English.lproj/Preferences.nib: Added Sparkle checkbox.

English.lproj/Read Me.nib: Leopard-ized with source list coloring,
highlight and removed focus ring (which caused artifacts anyway).

English.lproj/Snooze until.nib: Use new natural language date strings
and calendar button bezel style.

Info-Pester.plist: Updated for 1.1b5. Added Sparkle support.

NJRDateFormatter.m: Comment out debug logging on every keystroke.

PSAlarmSetController.[hm]: If "-" image exists (on Leopard), don't
draw it with text as well.

PSAlerts.m: Don't describe bounce alert (which is present for
backwards compatibility, but doesn't work yet in this version).

PSPowerManager.m: Temporarily disable; untested in this version.

Pester.xcodeproj: Change Development/Deployment to Debug/Release.
Link to Sparkle. STRIP_INSTALLED_PRODUCT=NO on release version for
now (eventually, can investigate using symbol files).

Read Me.rtfd: Updated for 1.1b5. Use real links. Clean up release
notes. Credit Sparkle and Date::Manip. Clean up styles so they look
better in the read me viewer. Fix Omni link.

Sparkle.diff: Changes to Sparkle, which is included as an external.
These aren't yet automatically applied.

Updates/Application icon.png: The icon converted to a PNG. This will
probably go away as it's too big.

Updates/release-notes.css: Release notes CSS based on the example that
comes with Sparkle.

Updates/release-notes.html: Dummy release notes file; nobody should
see this yet.

Updates/updates.xml: Initial Sparkle appcast file.

package-Pester.sh: Update for xcodebuild, Sparkle, etc. No longer
include source in download.
