# This script should be run in a build phase that should occur 
# before the 'Compile Sources' build phase for your target. 
# Make sure to check the checkbox that says: 
# "Run script only when installing."
# You only want to do this when making an archive for ad hoc distribution

# Expected environment variables
# From XCode:
#  * PROJECT_DIR
#  * PROJECT_NAME
#  * TARGET_NAME
# From User-defined Build Settings:
#  * JIRA_PREFIX - A string like 'MYPROJ' that starts every JIRA issue.

## STEP 1: Update the build version number in the plist files BEFORE building


# The main Plist
MASTERPLIST=${PROJECT_DIR}/${PROJECT_NAME}/${PROJECT_NAME}-Info.plist

# This target's plist
TARGETPLIST=${PROJECT_DIR}/${PROJECT_NAME}/${TARGET_NAME}-Info.plist

# This file is over-written on every archive
RELEASENOTES=${PROJECT_DIR}/Build/releaseNotes.md

# This file is used for the git commit
COMMITMESSAGE=${PROJECT_DIR}/Build/commit.md

# This is a list of Jira issues done since the last build
JIRAISSUES=${PROJECT_DIR}/Build/jira.md

# Every release's release notes are appended to this file
CHANGELOG=${PROJECT_DIR}/Build/changeLog.md

# temp file for atomic changes
TEMP=${PROJECT_DIR}/Build/changeLog.md.temp

# current date stamp
NOW=`date +"%Y/%m/%d %H:%M"`

# Adapted From: http://stackoverflow.com/a/15483906/772526
# This splits a two-decimal version string, such as "0.45.123", allowing us to increment the third position.

# get the full version string FROM THE MASTER PLIST
VERSIONNUM=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$MASTERPLIST")

# extract the third part
NEWSUBVERSION=`echo $VERSIONNUM | awk -F "." '{print $3}'`

# increment it by 1
NEWSUBVERSION=$(($NEWSUBVERSION + 1))

# reconstruct the new version string
NEWVERSIONSTRING=`echo $VERSIONNUM | awk -F "." '{print $1 "." $2 ".'$NEWSUBVERSION'" }'`

# ...as well as CFBundleVersion
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $NEWVERSIONSTRING" "$MASTERPLIST"
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $NEWVERSIONSTRING" "$TARGETPLIST"

## STEP 2: Create a release note entry prepopulated from git logs. Insert that into
##         the changelog file

# Get JIRA issues resolved
cd ${PROJECT_DIR}
/bin/rm $JIRAISSUES 2>/dev/null
# Look at all git commit logs until the last build
# Extract all lines that start with the JIRA_PREFIX or with a '!'
# Insert a '* ' in the beginning of every extracted line (slurping the '!', if present)
git log | perl -pe 'last if /^ *Build/' | grep -e "^ *${JIRA_PREFIX}" -e '^ *!' | perl -pe 's /^[ !]+/* /' > $JIRAISSUES

/bin/rm $TEMP 2>/dev/null
echo "## Build $NEWVERSIONSTRING :: $NOW :: $TARGET_NAME ####################" > $TEMP
echo "" >> $TEMP
cat $JIRAISSUES >> $TEMP
echo "" >> $TEMP
cat $CHANGELOG >> $TEMP

/bin/mv $TEMP $CHANGELOG


############################################################################################
## STEP 3: Open the changelog file, giving the user to update the option of changing the
##         release notes



# open with TextEdit, -W => Wait till exit, -n => open as a new app even if the app is already running
open -a /Applications/TextEdit.app -W -n $CHANGELOG


############################################################################################
## STEP 4: Create a separate releaseNotes file. This will be used for the HockeyApp upload


/bin/rm $RELEASENOTES

# Take the first chunk of text out and put it into the release notes
perl -ne 'if (/^\#\#\s*Build\s/i) { exit if $found++ == 1; $first = 1} elsif ($first && !/\S/) { $first = 0; } else { print; }'  $CHANGELOG > $RELEASENOTES


############################################################################################
## STEP 5: Final git commit. Commit changes to the plist files, changelog and releasenote
##         files.


# now make a git commit
/bin/rm $COMMITMESSAGE 2>/dev/null

echo "Build $NEWVERSIONSTRING :: $NOW" > $COMMITMESSAGE;
echo "" >> $COMMITMESSAGE;
cat $JIRAISSUES >> $COMMITMESSAGE
cd ${PROJECT_DIR}
git add $CHANGELOG $COMMITMESSAGE $JIRAISSUES $RELEASENOTES $MASTERPLIST $TARGETPLIST
git commit -q -F $COMMITMESSAGE
