April 2023 - 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

problems with yahoo_get

by Cristián Arturo Ducoing Ruiz

Hello dear colleagues, I'm using yahoo_get with my students and they have had problems getting the data. They are using computers with Windows 10 and the Gretl version 2022-02-02. Some students with the latest Gretl version have had the same problem. We have used the following code: include yahoo_get.gfn #package nulldata 10220 setobs 7 1946-01-01 --time-series SP500 = yahoo_price("^GSPC", 1) #SP500 After that, they get this message: "data error". Meanwhile, I get the data without any inconvenient (I'm using Windows 10 Education and the last Gretl version) Any clues? The server? any security certificate? Kind regards -- Atte.

v1.0 of latextab out now

by Artur T.

Dear gretl users, I am excited to announce the release of version 1.0 of the "latextab" package for creating Latex code representing a gretl matrix as a Latex table. This version includes a number of significant changes and improvements, which provide a better user experience and greater utility. One of the major changes in version 1.0 is a full refactoring of the package, which includes a new user-interface and some parameter renaming. These changes were made to simplify the package and make it more intuitive to use. See the sample script here: https://gretl.sourceforge.net/current_fnfiles/latextab.gfn Best, Artur
