An update to the IDL 7.0 Workbench is now available on the ITT VIS
workbench update site. The IDL 7.0.1 update provides a patch to the
IDL Workbench that significantly speeds up the IDL code parser. When
the IDL Workbench starts, it needs to parse all PRO code on your IDL
path, to enable syntax highlighting, the outline view, content assist,
hover help, and open declaration. This parsing happens in a background
thread, but if you have a single CPU, or you have a large number of
files on your path, or have files out on a network drive, then you
might have experienced some slowdown in the IDL user interface. With
the update to IDL 7.0.1, the parsing speed should be about 4 times
faster, with even greater speed if your files are on a network drive.
In addition, the status bar now provides a percent complete for the
Analyzing Code job, which gives you a visual indication of how quickly
it will finish.

To install the update, do the following steps:
1. Log in as an administrator (or root), or ensure that you have write
permission to the IDL7.0 install directory on your machine.
2. Open up the IDL Workbench application, and go under "Help->Software
Updates->Find and Install..." menu item.
3. Once the Wizard appears (it may take a few moments), select "Search
for updates of the currently installed features", then click "Finish".
If a dialog appears about "Update Site Mirrors", be sure to select
"Automatically select mirrors" and then "OK".
4. After a few minutes (it needs to search both the ITT VIS and
Eclipse web sites), you should see a list of available updates. Be
sure to *select* the "ITT VIS->Workbench Updates->IDL Development
Tools 7.0.1". Be sure to *deselect* all Eclipse Project Updates.
5. Click "Next", accept the license, then "Next", then "Finish".
6. When the Feature Verification dialog appears, just click "Install
All".
7. Restart the IDL Workbench.

Verify the installation:
To verify that the install was successful, when the IDL Workbench
starts, the "Analyzing Code" job in the status bar should now report a
percent complete. As another test, bring up the "About IDL Workbench"
dialog. Note that the IDL version is still 7.0.0. However, if you then
click on "Feature Details", you should see that the IDL Workbench
feature is now version 7.0.1.

just my two cents, but i find the words "We want you to..." very scary.
Can Clippy be far away?

Cheers,

Sounds like heaven to me. Are there any books there? :-)

Hah! What will happen is that five years ago I'll make that mistake
again, and get mad at myself for wasting two days five years from now
cause I didn't remember it.

Want to borrow a chicken to sacrifice?

But at least at the end of the two days the lesson
had been seared into your brain so indelibly that you
will never make the same mistake again. I seem to be
making mistakes that are impossible to reproduce,
leading me to the conclusion someone is practicing
black magic on me. :-(

Cheers,

David

P.S. Humm. Perhaps that fetish I brought back from Benin,
the heart of Voodoo in Africa...

My cycle on this is about two weeks.

I'll be programming in fortran (where the correct syntax is "a < b") and then switch back
to IDL, use the same syntax, and wonder why the hell that particular logical test is
*always* true.

Then I kick myself.

Then I go back to fortran coding.

Repeat as necessary.
