April 2022 - Gretl-users - gretlml.univpm.it

by Artur Tarassow

Dear all, some weeks ago I've started to switch to the sublime editor (https://www.sublimetext.com/) for writing gretl code. Even though I like the simplicity of the gretl editor and its features such as syntax highlighting and auto-itendation, it lacks some features of modern IDEs such as "goto-anything", "goto-definition", custom keybindings, fancy themes, git-implementation, snippets etc. which make life much easier when working on larger projects. Don't get me wrong, the gretl editor is great but was _never_ supposed to become a proper software-development IDE but rather has another focus which is totally fine. So I started to write the "Hansl-Gretl-Language" package for sublime which includes the following features: - 3 gretl build-systems (client mode, batch mode, and REPL mode) for executing hansl code by means of sublime (plots are also working!) - syntax-highlighting - completion of gretl commands, accessors and keywords - some snippet examples for speeding up coding The project still has the following (known) issues: - no auto-itendation (still have to figure out how this works) - issues with some corner-cases which are not syntax-highlighted (regex can become so hard!) The package can be downloaded through sublimes package control system, and can be found here: https://packagecontrol.io/packages/Hansl-Gretl-Language If somebody wants to participate on this project, check out the code on my github repository: https://github.com/atecon/Hansl-Gretl-Language For those interesting in the sublime editor, check out "OdatNurd"'s brilliant tutorials on youtube: https://www.youtube.com/user/nurdz Enjoy the package, Artur

Will Gretl add a way to interact with Scilab?

by tenghuanbin＠foxmail.com

Since Gretl has already got the Octave support, and Scilab, which has a great econometrics toolbox "Grocer", may be better than Octave in economic practice, will gretl add the Scilab support for users? Thank a lot!

low to high frequency simply by repeating values

by Sven Schreiber

Hi, my seemingly simple problem is this: in a quarterly dataset I have a series where valid values are only given for the respective first quarters, something like this: a NA NA NA b NA NA NA c .... I want to repeat and copy those values (a,b,c...) over to the other quarters of the respective years and fill the NAs with that. (So annual values are simply distributed over the quarters by repitition.) However, I'm struggling to get the tdisagg() function to do that. Yes, I have read the corresponding chapter 9 of the guide. Any hints or examples will be appreciated. I would prefer to do this via scripting, not via the GUI, to automate it later. thanks sven

Using foreign libraries, such as Python possible?

by Fred Engst

Thank Sven for that great one-liners! As I read in the user’s guide, we can actually invoke R library and use it to meet all of our needs for functions. I’m just wondering if there is any chance that we can use Python library the same way as we do with R. Best, Fred

Is there a string find function in gretl?

by Fred Engst

Hi Allin and others on the gretl team, I tried to find a simple string function similar to OX’s strfind() function, or Excel’s find() function, that gives me the position of a text string in another text string and couldn’t seem to find one. All the functions in the “Strings” section gives something else then what I want, it seem. Best, Fred
