pgxn utils

What is it?

It aims to be a set of task to help PostgreSQL extension's developers to focus more on the problem that they wants to solve than in all structure and files and control files need to PGXS to build the extension.

How to install it?

If you have pgxn client installed you can do:

pgxn install pgxn_utils

Or you can install it by rubygems:

gem install pgxn_utils

How it works?

It is all about tasks. Let's see what tasks we have:

$ pgxn_utils help
Tasks:
  pgxn_utils bundle [extension_name]  # Bundles an extension.
  pgxn_utils change [extension_name]  # Change META's attributes in current extension.
  pgxn_utils help [TASK]              # Describe available tasks or one specific task
  pgxn_utils release filename         # Release a extension
  pgxn_utils skeleton extension_name  # Creates an extension skeleton in current directory.

Creating a new extension

$ pgxn_utils skeleton my_cool_extension
      create  my_cool_extension
      create  my_cool_extension/my_cool_extension.control
      create  my_cool_extension/META.json
      create  my_cool_extension/Makefile
      create  my_cool_extension/README.md
      create  my_cool_extension/doc/my_cool_extension.md
      create  my_cool_extension/sql/my_cool_extension.sql
      create  my_cool_extension/sql/uninstall_my_cool_extension.sql
      create  my_cool_extension/test/expected/base.out
      create  my_cool_extension/test/sql/base.sql

Thats it! Just start coding! ":)

Changing something

Well suppose you want to change the default maintainer's name and the license, well just do:

$ pgxn_utils change my_cool_extension --maintainer "Dickson Guedes" --license bsd
    conflict  META.json
Overwrite /tmp/my_cool_extension/META.json? (enter "h" for help) [Ynaqdh] d
{
     "name": "my_cool_extension",
     "abstract": "A short description",
     "description": "A long description",
     "version": "0.0.1",
-    "maintainer": "The maintainer's name",
+    "maintainer": "Dickson Guedes",
-    "license": "postgresql",
+    "license": "bsd",
     "provides": {
        "my_cool_extension": {
           "abstract": "A short description",
           "file": "sql/my_cool_extension.sql",
           "docfile": "doc/my_cool_extension.md",
           "version": "0.0.1"
        }
     },
     "release_status": "unstable",

     "generated_by": "The maintainer's name",


     "meta-spec": {
        "version": "1.0.0",
        "url": "http://pgxn.org/meta/spec.txt"
     }
  }
Retrying...
Overwrite /tmp/my_cool_extension/META.json? (enter "h" for help) [Ynaqdh] Y
       force  META.json
   identical  my_cool_extension.control

It will wait you decide what to do.

For all switches that you can use with change, type:

$ pgxn_utils help change
Usage:
  pgxn_utils change [extension_name]

Options:
  -p, [--target=TARGET]                  # Define the target directory
                                         # Default: .
  -m, [--maintainer=MAINTAINER]          # Maintainer's name <maintainer@email>
  -a, [--abstract=ABSTRACT]              # Defines a short description to abstract
  -l, [--license=LICENSE]                # The extension license.
  -v, [--version=VERSION]                # Initial version
  -d, [--description=DESCRIPTION]        # A long text that contains more information about extension
  -b, [--generated-by=GENERATED_BY]      # Name of extension's generator
  -t, [--tags=one two three]             # Defines extension's tags
  -r, [--release-status=RELEASE_STATUS]  # Initial extension's release status

Change META's attributes in current extension.

Bundling and Releasing!

Well, since you finished your work you can bundle it to send to PGXN.

Bundle it:

$ pgxn_utils bundle my_cool_extension
Extension generated at: /home/guedes/extensions/my_cool_extension-0.0.1.zip

and release it:

$ pgxn_utils release my_cool_extension-0.0.1.zip
Enter your PGXN username: guedes
Enter your PGXN password: ******
Trying to release my_cool_extension-0.0.1.zip ... released successfully!
Visit: https://manager.pgxn.org/distributions/my_cool_extension/0.0.1

You can export PGXN_USER and PGXN_PASSWORD environment variables to avoid type username and password everytime.
