I have been using Nova as my main text editor for the last few months. It is a Mac-only, extendable editor that has a great "remote mode" which allows me to edit files on remote servers from my laptop. There are many extensions for handling various languages and data formats, but no IDL extension. So I created a simple one. It is definitely not a complete language specification that makes use of all of Nova's extension capabilities, but it does basic syntax highlighting and some code completion.
You can download the extension through the app — just search for "IDL" in the extension library. Check out the source code and contribute to the project on the GitHub repo.
IDL 8.8 was released recently. The main changes are:
- A new
SOBOLSEQUENCEfunction to generate numbers from the Sobol sequence.
- Support for more video formats: DV (Linux only), RAW, Bitmap (Windows only), HEVC, VC-1, and VP-8.
- Many library updates.
- Fixed various bugs.
- IDL Workbench themes, e.g.., dark mode.
See the release notes for more details.
- Using the Intel Math Kernel Library (MKL) for matrix operations now. My experience has been that MKL is a highly optimized implementation of BLAS, a library of low-level matrix and vector operations. Matrix operations, such as the
##, should be faster now, but I don't have 8.7.3 to test on, yet.
BLASS_GEMMmatrix multiplication routine with many options for controlling the operation. This is a consequence of adding the MKL.
SOBOLSEQUENCEroutine to generate numbers from the Sobel sequence.
UPDATE 2/25/2020: I have IDL 8.7.3 now and did some simple testing of the performance between IDL 8.7.3 and IDL 8.6 for
##. Mean time for multiplying two 50,000 by 50,000 element matrices went from 76.942 sec in IDL 8.6 down to 3.400 sec in IDL 8.7.3.
- I have no idea exactly when or how to find that out. ?
epochs is a Python package to handle configuration files specifying values which change over time.
For example, consider a configuration file
epochs.cfg containing the following:
[2019-04-09 20:27:15] value : 3 [2019-04-09 22:31:01] value : 5
Then value can be retrieved for various times:
>>> import epochs >>> ep = epochs.parse('epochs.cfg') >>> value = ep.get('value', datetime='2019-04-09 21:55:45') >>> print(value) 3 >>> value = ep.get('value', datetime='2019-04-09 23:15:40') >>> print(value) 5
If you provide a specification for the values in a configuration file, epochs can also validate a config file and provide values as the correct type and default value. For example, for a specification file containing:
[city] name : required=True, type=str streets : required=True, type=List[str] temp : required=False, type=float, default=0.0
Then an example configuration file following this specification:
[city] name : Boulder streets : [Broadway, Baseline, Valmont]
Then to parse the configuration file with a specification:
>>> import epochs >>> cf = epochs.parse('example.cfg', spec='spec.cfg') >>> name = cf.get('name', section='city') >>> print(name) Boulder >>> streets = cf.get('streets', section='city') >>> print(steets) ['Broadway', 'Baseline', 'Valmont'] >>> temp = cf.get('temp', section='city') >>> print(temp, type(temp)) 0.0
epochs is in PyPI. It can be installed with
pip install epochs
The epochs source code is available on GitHub.

IDL 8.7.1 adds the IDL Package Manager (IPM), a package manager for IDL libraries. You can install libraries from the Internet with a single command in IDL, even installing dependencies for the library if needed.
IDL 8.7.1 was released today. Check the What's New on the Docs Center for a comprehensive list of the new features.
Along with some performance improvements and library updates, there are two big new features:
- an IDL package manager
- machine learning classes (including a feed forward neural network class)
I will publish an article about the package manager shortly; I made IDLdoc, mgunit, and my personal library available through the package manager. I think this is now the best way to distribute IDL packages.
I am also excited to explore the machine learning classes. I will write more as soon we get 8.7.1 installed on our machines.
With these two new features, this is a powerful "bug fix" release.
