John Murray :: Think Do Keep

Think! Do! Keep! OOTS 2007 John Murray Senior Product Engineer

Exploiting the Slipstream
Plan your move
Make the break
Don’t lose control

Think!
Starting position
What is where?
How does it work now?
Goal
How do we want things to be?
What will we gain?
Devising change
What is to be altered?
In what sequence?
“Is that clear?”
Do we all know what we’re doing?

Think! – Umlanji
Picture your Caché or Ensemble classes
Create UML class diagrams directly from your class definitions
Accurate
Complete
Up to date
Understand someone else’s classes
Explain your classes to others

Umlanji’s Slipstreaming
Leveraging existing UML modelling tools
Umlanji generates XMI file from class definitions
Poseidon from Gentleware
Enterprise Architect from Sparx
others
Exploiting Caché Studio extensibility
Integrates as an add-in

Do!
Work accurately and efficiently
Focus effectively
Troubleshoot rapidly

Do! – Serenji
M and COS code editor running on Windows
Caché and Ensemble (INTs, MACs and INCs)
GT.M
Also M21, MSM and DSM
Syntax colouring as you type
Collapsible blocks for dotted-DOs and {…}
Boundary marking, and highlighting of unreachable code
‘ Live’ subroutine and extrinsic function calls
Tip showing comment and parameter mapping
Navigable – jump to target, go back
Bookmarks
Tabbed multi-document view, splittable panes

Doing More
Control interactive or background processes
Click in margin to set breakpoints, optionally conditional or deferred
Step in, over, out, run to here
Break on change of arbitrary expression
Break on error
Hover to see value of variable or expression
View symbol table at each stack level
Have direct access to execution context
e.g. change variables, then continue
Debug faulty code, understand functioning code

Serenji’s Slipstreaming
RE/parser
Parser for M syntax
Implemented in M
MSM-Workstation
Compact M engine, easily deployed
Runs on Windows
SourceView ActiveX control
Text editor component architected to permit plug-in parsers
Infrastructure for collapsible blocks

Keep!
Keep your work
Preserve changes over time
Give confidence to blaze a trail, knowing you can revert
Keep control
Parallel working serialized when necessary?
Been through correct testing and approval stages?
Right pieces in right places?
Fixes to previous product releases rolled forward to next one?
Reproducible build?

Keep! – VC/m
Version control, workflow and configuration management for:
M and COS code & data
Classes
Web pages (CSP, EWD, HTML)
Arbitrary text or binary files
Retain versions of your code as you change it
Control and integrate concurrent changes
Manage multiple release cycles
Specify workflow controlling how changes are deployed

VC/m’s Slipstreaming
Web browser technologies
DOM and Javascript
Script the manipulation of the Document Object Model
XML and XSLT
Serve pure data, and supply a transform that renders it presentable
Beyond Compare
Visual diff tool capable of accessing FTP sites
VC/m masquerades as an FTP site whose directory structure is optimized for the diff tasks a VC/m user needs to perform
Next version of BC implements Merge, so VC/m will benefit
