Using AGX on the Command Line

AGX’ Eclipse plugin comes with some handy menu entries, e.g. for

  • the import of profiles
  • the generation of code from models

However, apart from the fact that Papyrus runs only in Eclipse [1] there is no need to use Eclipse for using AGX. In fact, everything Eclipse does is calling AGX.

And you can do that yourself!

[1]There is a standalone version of Papyrus on, but it’s not supposed to be used since all papyrus development moved to te Eclipse plugin project.

Call AGX without arguments

Try it! Change to the directory where you installed AGX, e.g. your workspace. Then call bin/agx. If you call AGX without arguments, you are presented with the following information:

user@host:~/$ cd workspace/
user@host:~/workspace/$ bin/agx
CRITICAL No control flags given.
Usage: agx UMLFILE options

  -h, --help            show this help message and exit
  -o /target/path, --output-directory=/target/path
                        Write generated code to TARGET
  -p /path/to/profile1.uml;/path/to/profile2.uml, --profiles=/path/to/profile1.uml;/path/to/profile2.uml
                        Comma seperated Paths to profile file(s)
  -e profilename1;profilename2, --export-profiles=profilename1;profilename2
                        Comma seperated profile names to export for model
  -l, --listprofiles    List of available profiles
  -i, --info            AGX Version and flavour info.
  -d, --debug           Additional output of debug information.
  -m, --postmortem      Enable postmortem debugger.
  -t, --listtemplates   list available model templates
  -c template_name, --create=template_name
                        Create a model from a model template by name. (see
                        '-t' option)
  -s, --short           option for short machine readable messages

AGX Commandline Options

Show help message (-h)

Calling AGX with the -h option (or –help) will simply show the information above.

List the available profiles (-l)

If you want to see the list of the profiles registered with AGX, just call AGX with the -l (or –listprofiles) option.

You will be presented with output similar to this. (Note that ”...” here shows that some part ot the path has been omitted):

user@host:~/workspace_indigo/$ bin/agx -l
generator /.../agx.generator.generator/src/agx/generator/generator/profiles/generator.profile.uml
sql /.../agx.generator.sql/src/agx/generator/sql/profiles/sql.profile.uml
dexterity /.../agx.generator.dexterity/src/agx/generator/dexterity/profiles/dexterity.profile.uml
pyegg /.../agx.generator.pyegg/src/agx/generator/pyegg/profiles/pyegg.profile.uml
plone /.../agx.generator.plone/src/agx/generator/plone/profiles/plone.profile.uml
buildout /.../agx.generator.buildout/src/agx/generator/buildout/profiles/buildout.profile.uml
zca /.../agx.generator.zca/src/agx/generator/zca/profiles/zca.profile.uml

Please refer to the User Documentation or Profile Reference to find out what the profiles can do for you.

Export profiles to the file system (-e)

If you need one or more profile files for use with a model, you can use the -e or –export-profiles option to get the most recent version of the profile known to AGX.

List installed versions of AGX (-i)

This option is helpful to determine which version of AGX and generators you have installed. Just call AGX with the -i option to get some output like this:

AGX 1.0a2 (Reincarnation)
Installed generators:
    agx.generator.generator (1.0a1)
    agx.generator.sql (1.0a1)
    agx.generator.dexterity (1.0a1)
    agx.generator.uml (1.0a1)
    agx.generator.pyegg (1.0a1)
    agx.generator.plone (1.0a1)
    agx.generator.buildout (1.0a1)
    agx.generator.zca (1.0a1)

List the available templates (-t)

You can get a listing of the available templates by calling AGX with the -t or –listtemplates option. This will yield output similar to the following:

user@host:/opt/agx/$ bin/agx -t
sql_example: SQL Product
    A simple SQL content model with two sql_content classes.

dexterity_product: Dexterity Product
    A vanilla Plone Dexterity model that contains the necessary
    settings for content stuff for Plone.

python_egg: Python Egg
    A minimal Python egg model.

plone_product: Plone Product
    A vanilla Plone model that contains the necessary settings
    for a Plone product: generic setup profile etc.
    but without content classes.

generator_example: Generator Example
    An example model for a generator generator.
    (Advanced users only!)

dexterity_example: Dexterity Example
    A ready-to-run Plone Dexterity example that demonstrates
    how to model content stuff for Plone.
    Contains a set of example classes.

The listed templates can be used like in the following section.

Create a model from a template (-c)

A call to AGX with the -c option followed by one of the template names known to AGX will create a model from this template (i.e. .di, .notation and .uml files), an .agx settings file and a folder called ‘uml_profiles’ containing the relevant profiles, as well as a log file documenting the process:

user@host:/opt/agx/$ ../bin/agx -c sql_example
INFO  Export to target: './uml_profiles'
INFO  Export 'sql'
INFO  Export 'pyegg'
user@host:/opt/agx/$ ls
agx.core.log  model.di  model.notation  model.uml  model.uml.agx  uml_profiles
user@host:/opt/agx/$ tree
├── agx.core.log
├── model.di
├── model.notation
├── model.uml
├── model.uml.agx
└── uml_profiles
    ├── pyegg.profile.uml
    └── sql.profile.uml

1 directory, 7 files

Thus, AGX can be used almost like paster to generate useful structures and files on the file system, with the added bonus of a model so you can develop your application further.
