Make’ing PostGIS database

I’ve extended Sean’s idea of baking PostGIS-enabled databases using GNU Make a little bit and prepared new version of Makefile.postgis.

How to use it:

  • Install it to save yourself some typing: 
    $ ln -s Makefile.postgis Makefile
  • Run make to get basic usage information: 
    $ make
****** Makefile.postgis usage ******
*** Create new PostGIS database:
	DBNAME=mydb make -f Makefile.postgis create
*** Drop PostGIS database:
	DBNAME=mydb make -f Makefile.postgis drop
*** Check if database exists and PostGIS if enabled with PostGIS:
	DBNAME=mydb make -f Makefile.postgis check
*** Check if database exists:
	DBNAME=mydb make -f Makefile.postgis check-db
*** Check if database is enabled with PostGIS:
	DBNAME=mydb make -f Makefile.postgis check-postgis
  • Check if your database exists: 
    $ DBNAME=mydb make check-db
****** Makefile.postgis ******
****** Database 'mydb' not found
  • Create your database with PostGIS extension installed: 
    $ DBNAME=mydb make create
****** Makefile.postgis ******
****** Creating database 'mydb'...
****** Loading PostGIS into 'mydb'...
  • Check what has been created and installed: 
    $ DBNAME=mydb make check
****** Makefile.postgis ******
****** Database 'mydb' found
****** Makefile.postgis ******
****** Database 'mydb' is enabled with PostGIS
1.4 USE_GEOS=1 USE_PROJ=1 USE_STATS=1
  • When you don’t need your database anymore, just drop it: 
    $ DBNAME=mydb make drop

colormake on Mac OS X

I have just discovered colormake utility – a simple wrapper around make to colorize its output.

colormake is really helpful for someone who heavily works in Unix shell environments to visually analyse messages generated during programs compilation. Simply, colors are used as another language for communication with a user, complementing letters printed out to the console. The colormake wrapper in combination with clean console fonts like Terminus serve as a great tandem in hacker daily job.

First, I started to use colormake 0.2 on Ubuntu Linux: 

$ sudo apt-get install colormake

Next, I tried it on Mac OS X 10.5, though with no luck. Basically, because of subtle differences in Bash and format of GCC output messages. So, simple patch (colormake-0.2-mloskot.patch) is required to get colormake 0.2 working on Mac OS X. I’ve sent this patch to Bjarni – the author of colormake, so perhaps he will like to include it in next (0.3?) version. BTW, thanks to Bjarni for the colormake tool!
