Sketchnote: Fun With Dead Languages: Damian Conway

| geek, sketchnotes

Here are my notes from Damian Conway’s talk “Fun With Dead Languages”. =) I heard him give an older version of this talk years ago, and I’m amused to find that my Latin dabbling gave me a much deeper appreciation of this talk.

Sample code for allowing drag-and-drop of Notes/Domino documents (including email) to a table in a plugin

Posted: - Modified: | geek, lotus

Because I had to piece this together from examples on the Internet, and probably other people do too:

Transfer[] transferArray = new Transfer[]{
    transferArray, new DropTargetAdapter() {
        public void drop(DropTargetEvent event) {
            TableItem item = (TableItem) event.item;
            // You can access the object with item.getData()
            try {
                Session session = NotesFactory.createSessionWithFullAccess();
                if (event.data instanceof URIDescriptor[]){ 
                    URIDescriptor[] droppedURL = (URIDescriptor[]) event.data;
                    for (int i = 0; i < droppedURL.length; i++) { 
                        URI uri = ((URIDescriptor) droppedURL[i]).uri;
                        Document d = (Document) session.resolve(uri.toString());
                        // Do things with the document
            } catch (Exception e) {
            } finally {

Use session.resolve instead of db.getDocumentByURL to retrieve a document from a plugin, as both session.getAgentContext() and session.getCurrentDatabase() will return null.

Custom fields in Lotus Notes / Domino? You may need to set the SUMMARY field flag

| geek, lotus

It took me a few hours to figure out that I needed the SUMMARY field flag, so I thought I’d save you the struggle if you ever need to create a view with custom columns.

I was trying to create a view that showed the custom fields I’d added to an RSVP message: RSVPCampaign, RSVPCode, and other details. I had created a Lotus Notes button that sent me an e-mail with the information in hidden fields. I successfully processed the extra fields using a LotusScript agent. I wanted to create a view that showed the results so that I didn’t have to keep clicking on the button and checking my mail. Using a view would make it easier for me to share these tools with other people, because I figured out how to create a button that creates a view.

I couldn’t figure out how to get my custom fields to display, though. They showed up in @DocFields, but @IsAvailable(RSVPCampaign) was always false.

I read about all of the functions in the Formula language. I experimented with @GetField, field names, and other ways to access data. I dug through documentation and websites (most of which assumed people already knew things like this). Frustrated, I opened the properties dialog and started systematically going through the fields on my RSVP messages.

It took me several passes to notice that the regular fields had “Field Flags: SUMMARY” and my custom fields didn’t.

After some quick searching, I realized that I needed to set the summary field flag. So I rewrote my RSVP mailing function to include lines like this:

Dim item As NotesItem
Set item = New NotesItem(doc, "RSVPCode", code) item.IsSummary = True

I tested my new RSVP mailing button, and my view worked!

So if you’re stumped because your custom fields don’t work in view selection formulas or in column formulas, set the summary flag on the field when you set the field, and you should be good to go.

I wonder how I could’ve learned that faster. Reading other people’s source code would help. Forums are useful, too. Part of it involves picking up the jargon so that I know how to phrase my searches. Anyway, I fixed it! =D

Even more awesome LotusScript mail merge for Lotus Notes + Microsoft Excel

Posted: - Modified: | geek, lotus
UPDATE: May 20, 2011 – David Turner has shared his excellent improvements. Check them out!

UPDATE: May 28, 2010 – fixed errors caused by default Option Declare. Thanks to Lisa Harnett for the feedback!
UPDATE: Oct 19, 2010 – fixed Quit(). Thanks to Vance for the feedback! Also, clarified tokens.

Based on the feedback on my Lotus Notes mail merge from a Microsoft Excel spreadsheet (2009), I’ve refined my merge script to make it more awesome. How is it more awesome?

  • Prompts you for drafting or sending
  • Saves sent messages
  • Allows you to customize the subject
  • Uses [ ] instead of < and > for built-in tokens ([to], [cc], [subject]) for less HTML confusion in blog posts and replies
  • Displays number of sent messages and errors
  • Closes the Microsoft Excel spreadsheet afterwards

The search-and-replace tokens are defined in the first row of your Microsoft Excel spreadsheet. The script searches for them in the message body, replaces them with the appropriate values from the current row, and either saves the message as the draft or sends the message. There are a few built-in tokens for this script ([to], [cc], [subject]) – these are case-sensitive, so enter them exactly like that. All the other tokens are up to you, so you could use FOO and BAR as search-and-replace tokens if you want.

Tokens are replaced only in the message body. If you want a variable subject line, use a formula to calculate the subject in a column with the [subject] header.

As always, test your mail merges with a small list before using it for your entire list. Create an agent and call it something like “Mail merge”. Edit the agent and set the type to LotusScript. In the (Declarations) section, add

%Include "lsconst.lss"

In the “Initialize” section, put in:

I had a totally awesome day at IBM today, crunching some data and
doing some nifty photocloud visualizations of all the people who had
blogged about a certain topic. I sorted it by domain in order to
collocate people from the same lab, and resized the photos according
to the number of posts they had made, linking each picture to the
respective blogs. I then ran the same analysis on their bookmarks.
Next week, I’m going to do a 2D plot… =)

It was _tons_ of fun hacking together a little Java program to do the
analysis. I had to look up a lot of things in order to do the first
program. It took me a while to dump SAX in favor of DOM, but once I’d
gotten the XML parsing code out of the way, I wrote the data analysis
quickly. My code wouldn’t win points for elegance or efficiency, but
it works. I wish I had either Ruby or Python on that system – heck, I
could do this stuff in Emacs Lisp. I think I’ll go install the Windows
versions of my favorite programming languages as soon as possible,
although I might have to clear it with IBM first.

Today put me firmly back in the programming/hacking camp. I couldn’t
pry my fingers off the keyboard. =) Mark had to call me to make sure I
didn’t miss the 3:55 bus. I just had so much fun writing glue code and
crunching all the data. In terms of geek stuff, this is where I

Ruby: Turn bash.org quotes into a fortune file

Posted: - Modified: | ruby

The following code turns XML quotes from bash.org (a popular IRC quotes server) into a fortune-cookie file.
Handy for using with ../emacs/flashcard.el and my ../emacs/flashcard-config.el, which pops up a fortune
every time I get a correct answer.


require 'rss/1.0'
require 'cgi'
require 'net/http'
host = Net::HTTP.new('bash.org', 80)
if ARGV[0] then
   resp, data = host.get('http://bash.org/xml/?top&below=' + ARGV[0], nil)
   resp, data = host.get('http://bash.org/xml/?top', nil)
parsed = RSS::Parser.parse(data, false)
parsed.items.each { |x| puts CGI::unescapeHTML(x.description.gsub('
', "\n")); puts "%\n" }

Call like this:

ruby bash-org-to-fortune.rb > bash; strfile bash; fortune bash

# or to get the top quotes with score < 1000
ruby bash-org-to-fortune.rb 1000 > bash; strfile bash; fortune bash
