Abstract

This invention is a method for creating systems that support visual editing and manipulation of arbitrary (any language) textual source code as graphical flowcharts. The cornerstone of this invention is a textual Flow Structure Markup Language (FSML) that encodes algorithmic flow information representing the logical procedural intent of a file (or files) of textual code. The FSML can be placed within a file containing both text source code and FSML encoded flow information, or in parallel as a secondary file that stores the flow information, or as an attribute in a database record wherein each record can also contain a single procedural instruction of the procedural language or reference therein. In all embodiments the flow information is synchronized with the text code instructions so that each line, or instruction of text code, has a corresponding line, tag, or identifying mark that denotes, or encodes, the type of flow that a text code instruction represents.

Claims

1. An apparatus that develops an algorithmic representation based on a textual source code, comprising:

first logic, the first logic deriving algorithmic flow information from the textual source code; and

second logic, the second logic using hierarchical Flow Structure Markup Language grammar to encode the algorithmic flow information and the textual source code to create the algorithmic representation.

2. The apparatus of claim 1, wherein the algorithmic representation is viewable as a flowchart and wherein the flowchart can be graphically edited.

3. The apparatus of claim 1, wherein the Flow Structure Markup Language grammar is Extended Markup Language (XML)-complaint Flow Structure Markup Language grammar.

4. The apparatus of claim 1, wherein the Flow Structure Markup Language grammar is non-XML-complaint Flow Structure Markup Language grammar.

5. The apparatus of claim 2, wherein editing the flowchart results in the textual source code being automatically edited.

6. A method for developing an algorithmic representation based on a textual source code, the method comprising the steps of:

deriving algorithmic flow information from the textual source code; and

using hierarchical Flow Structure Markup Language grammar to encode the textual source code and the algorithmic flow information to create the algorithmic representation.

7. The method of claim 6, wherein the algorithmic representation is viewable as a flowchart, wherein the flowchart can be graphically edited.

8. The method of claim 6, wherein the Flow Structure Markup Language grammar is XML-complaint Flow Structure Markup Language grammar.

9. The method of claim 6, wherein the Flow Structure Markup Language grammar is non-XML-complaint Flow Structure Markup Language grammar.

10. The method of claim 7, wherein the textual source code is edited based on the edit of the flowchart.

11. A computer program for developing an algorithmic representation based on a textual source code, the computer program being embodied on a computer-readable medium, the computer program comprising:

a first logic, the first logic deriving algorithmic flow information from the textual source code; and

a second logic, the second logic using hierarchical Flow Structure Markup Language grammar to encode the textual source code and the algorithmic flow information to create the algorithmic representation.

12. The computer program of claim 11, wherein the algorithmic representation is viewable as a flowchart, wherein the flowchart can be graphically edited by an editing logic.

13. The computer program of claim 11, wherein the Flow Structure Markup Language grammar is XML-complaint Flow Structure Markup Language grammar.

14. The computer program of claim 11, wherein the Flow Structure Markup Language grammar is non-XML-complaint Flow Structure Markup Language grammar.

15. The computer program of claim 12, wherein a second editing logic edits the textual source code based on the editing of the flowchart.

16. A means for developing an algorithmic representation based on a textual source code, comprising:

deriving algorithmic flow information from the textual source code; and

using hierarchical Flow Structure Markup Language grammar to encode the textual source code and the algorithmic flow information to create the algorithmic representation.

17. The means of claim 16, wherein the algorithmic representation is viewable as a flowchart, wherein the flowchart can be graphically edited.

18. The means of claim 16, wherein the Flow Structure Markup Language grammar is XML-complaint Flow Structure Markup Language grammar.

19. The means of claim 16, wherein the Flow Structure Markup Language grammar is non-XML-complaint Flow Structure Markup Language grammar.

20. The means of claim 17, wherein the editing of the flowchart automatically edits the textual source code.
