git-promise

Add commands to run as branches merge down stream.

promise new <promise> <extension>

promise new tables sql

promise add <promise> <command>

mysql "ALTER TABLE table ADD some_column int"
promise add tables ALTER TABLE table ADD some_column int

promise pull <promise>

promise pull tables
mysql "source tables.sql"

promise resolve <promise>

promise resolve tables

Example

# Create promise for SQL
promise new tables sql

Dev server 1

# Add a line to our promise
promise add tables ALTER TABLE table ADD some_column int
# Push changes
git add -A && git commit && git push

Dev server 2

# Add a line to our promise
promise add tables ALTER TABLE table ADD some_column_other_column VARCHAR(32)
# Push changes
git add -A && git commit && git push

Test / Master server

# Pull changes
git pull
promise pull tables
cat tables.sql
  # ALTER TABLE table ADD some_column int
  # ALTER TABLE table ADD some_column_other_column VARCHAR(32)

# Apply changes
mysql "source tables.sql"

# Resolve changes
promise resolve tables
cat tables.sql # Empty

Pull and resolve should always be used together, in one sitting.

promise pull
do_something
promise resolve

promise add will overwrite the cache and should be done after promise pull.
