blockdiag generate block-diagram image file from spec-text file.

blockdiag generate block-diagram image file from spec-text file.

Features

• Generate block-diagram from dot like text (basic feature).

• Multilingualization for node-label (utf-8 only).

You can get some examples and generated images on blockdiag.com .

Setup

by easy_install

Make environment:

$ easy_install blockdiag

If you want to export as PDF format, give pdf arguments:

$ easy_install "blockdiag[pdf]"

by buildout

Make environment:

$ hg clone http://bitbucket.org/tk0miya/blockdiag
$ cd blockdiag
$ python bootstrap.py
$ bin/buildout

Copy and modify ini file. example:

$ cp <blockdiag installed path>/blockdiag/examples/simple.diag .
$ vi simple.diag

Please refer to spec-text setting sample section for the format of the simpla.diag configuration file.

spec-text setting sample

Few examples are available. You can get more examples at blockdiag.com .

simple.diag

simple.diag is simply define nodes and transitions by dot-like text format:

diagram admin {
  top_page -> config -> config_edit -> config_confirm -> top_page;
}

screen.diag

screen.diag is more complexly sample. diaglam nodes have a alternative label and some transitions:

diagram admin {
  top_page [label = "Top page"];

  foo_index [label = "List of FOOs"];
  foo_detail [label = "Detail FOO"];
  foo_add [label = "Add FOO"];
  foo_add_confirm [label = "Add FOO (confirm)"];
  foo_edit [label = "Edit FOO"];
  foo_edit_confirm [label = "Edit FOO (confirm)"];
  foo_delete_confirm [label = "Delete FOO (confirm)"];

  bar_detail [label = "Detail of BAR"];
  bar_edit [label = "Edit BAR"];
  bar_edit_confirm [label = "Edit BAR (confirm)"];

  logout;

  top_page -> foo_index;
  top_page -> bar_detail;

  foo_index -> foo_detail;
               foo_detail -> foo_edit;
               foo_detail -> foo_delete_confirm;
  foo_index -> foo_add -> foo_add_confirm -> foo_index;
  foo_index -> foo_edit -> foo_edit_confirm -> foo_index;
  foo_index -> foo_delete_confirm -> foo_index;

  bar_detail -> bar_edit -> bar_edit_confirm -> bar_detail;
}

Execute blockdiag command:

$ blockdiag simple.diag
$ ls simple.png
simple.png
