Preparing the data description for the metadata docu

Today I had to prepare a description of all the vector drawings I had in a project in a semi tabular form listing a folder, contained drawings and their column, column types and the length of the data in each column. In other words I needed to create a dataset description for the metadata document needed in my current project.

Obviously collecting such data for a drawing or two is fairly quick but manually fetching data for multiple components would a pain in the neck…

A script seemed to be the best option here so I decided to write one ;-) It searches for the drawings contained in folders (one level of nesting) and then lists the needed stuff. It can easily be adapted to list drawings in a root folder as well and to dig deeper in nested folders. It can also be adjusted to look for other types of components or to grab some info about the coordsystems used by them - I just needed the drawings though hence a rather simplistic version of the script was enough.

Anyways, feel free to use it if you like (simply add a c# script and replace its content with the attached). Bear in mind script lists info only for drawings contained in a folder.

Output example:

Topo200k
========================================

Drogi
----------------------------------------
ColumnName	DataType	FieldLength
ID	ColumnTypeInt32U	4
LENGTH	ColumnTypeFloat64	8
KLASA	ColumnTypeInt16	2
ID 2	ColumnTypeInt32	4
NUMER	ColumnTypeAText	16
----------------------------------------

Duze_rzeki_i_jeziora
----------------------------------------
ColumnName	DataType	FieldLength
ID	ColumnTypeInt32U	4
NAME	ColumnTypeAText	100
SHAPE_LENG	ColumnTypeFloat64	8
SHAPE_AREA	ColumnTypeFloat64	8
TOPO_CLASS	ColumnTypeInt32	4

 And the script:

using Manifold.Interop.Scripts;
using System;

class Script {
	static void Main() {
		pullDataDescription();
	}

    static void pullDataDescription()
    {
        //reference the app object first
        Manifold.Interop.Application manApp = new Manifold.Interop.Application();

        //grab doc object
        Manifold.Interop.Document manDoc = (Manifold.Interop.Document) manApp.ActiveDocument;

        //create output comments component
        Manifold.Interop.Comments cmt = manDoc.NewComments("Drawings&Data", false);
        cmt.Folder = null; //so it's always in the root folder

        //record the time this summary was created
        DateTime date = DateTime.Now;
        cmt.AddText("Report generated " + date.ToLongDateString() + " " + date.ToLongTimeString() + Environment.NewLine);
        cmt.AddText(writeBreakLine("*", 40) + Environment.NewLine);

        //iterate through components
        foreach (Manifold.Interop.Component cmp in manDoc.ComponentSet)
        {
            //check if this is a folder
            if (cmp.Type == Manifold.Interop.ComponentType.ComponentFolder)
            {
                Manifold.Interop.Folder fld = (Manifold.Interop.Folder)cmp;
                
                //write the folder name
                cmt.AddText(fld.Name + Environment.NewLine);
                cmt.AddText(writeBreakLine("=", 40) + Environment.NewLine);

                //iterate through drawings
                foreach (Manifold.Interop.Component fldCmp in fld.Children)
                {
                    //check if this is a drawing
                    if (fldCmp.Type == Manifold.Interop.ComponentType.ComponentDrawing)
                    {

                        Manifold.Interop.Drawing drw = (Manifold.Interop.Drawing)fldCmp; 

                        //write drawing name
                        cmt.AddText(drw.Name + Environment.NewLine);
                        cmt.AddText(writeBreakLine("-", 40));

                        //write headers for the tables
                        cmt.AddText("ColumnName" + "\t" + "DataType" + "\t" + "FieldLength" + Environment.NewLine);
                        //iterate through colums
                        foreach (Manifold.Interop.Column col in ((Manifold.Interop.Table)drw.OwnedTable).ColumnSet)
                        {
                            if (col.Category == (int)Manifold.Interop.ColumnCategory.ColumnCategoryNative)
                            {
                                cmt.AddText(col.Name + "\t" + (Manifold.Interop.ColumnType)col.get_Type()  + "\t" + col.Size + Environment.NewLine);
                            }
                        }
                        cmt.AddText(writeBreakLine("-", 40) +    Environment.NewLine);
                    }
                }
                //write the folder name
                cmt.AddText(writeBreakLine("=", 40));
                cmt.AddText("eof " + fld.Name + Environment.NewLine + Environment.NewLine + Environment.NewLine);
            }
        }
        //open the comments component
        cmt.Open();
    }

    //writes a 'break line'
    static string writeBreakLine(string character, int length)
    {
        string output = string.Empty;
        for (int n = 0; n < length; n++)
        {
            output += character;
        }
        output += Environment.NewLine;
        return output;
