Fault-tolerant dynamic editing of gui display and source code

A fault-tolerant method for editing an Original Source Code (OSC) document containing one or more statements, comprising the steps of:

• creating an Edited Source Code (ESC) document by editing a copy of said OSC document;
• parsing said ESC document;
• identifying any unparseable statements in said ESC document;
• and
• if any statements of said ESC document are unparseable, modifying said OSC document so as to incorporate only parseable statements from said ESC document.

A fault-tolerant method for editing an Original Source Code (OSC) document, said OSC document being structured into one or more source code groupings containing one or more statements, comprising the steps of:

• creating an Edited Source Code (ESC) document by editing a copy of said OSC document;
• comparing said OSC document with said ESC document to identify any source code groupings containing edits;
• creating a Delta Source Code Snippet (DSCS) document based on said identified source code groupings;
• parsing said DSCS document;
• identifying any unparseable statements in said DSCS document;
• and
• if any statements of said DSCS document are unparseable, modifying said OSC document so as to incorporate only the parseable statements in said DSCS document.

A fault-tolerant system for editing an Original Source Code (OSC) document, said OSC document being structured into one or more source code groupings containing one or more statements, comprising:

• means for creating an Edited Source Code (ESC) document by editing a copy of said OSC document;
• means for comparing said OSC document with said ESC document to identify any source code groupings containing edits;
• means for creating a Delta Source Code Snippet (DSCS) document based on said identified source code groupings;
• means for parsing said DSCS document;
• means for identifying any unparseable statements in said DSCS document;
• and
• if any statements of said DSCS document are unparseable, means for modifying said OSC document so as to incorporate only the parseable statements in said DSCS document.

A computer program product recorded on computer recordable medium for editing an Original Source Code (OSC) document, said OSC document being structured into one or more source code groupings containing one or more statements, comprising:

• computer readable means for creating an Edited Source Code (ESC) document by editing a copy of said OSC document;
• computer readable means for comparing said OSC document with said ESC document to identify any source code groupings containing edits;
• computer readable means for creating a Delta Source Code Snippet (DSCS) document based on said identified source code groupings;
• computer readable means for parsing said DSCS document;
• computer readable means for identifying any unparseable statements in said DSCS document;
• and
• computer readable means for modifying said OSC document so as to incorporate only the parseable statements in said DSCS document.
