Originally, Launchy was designed to be useful for people with multiple versions of Dyalog installed on their Windows machine(s).
However, over the years it evolved into an all-singing-all-dancing tool that allows to manipulate all sorts of parameters, so it's now a useful tool even if you have ony a single version of Dyalog installed on your machine.
Launchy simplifies the process making adjustments like...
PropertyExposeRoot
and otherssetup.dyalog
scriptIn addition to its main goal Launchy offers these features:
config.dcfg
for the currently selected version of DyalogLaunchy is self-contained and does not rely on anything. It is a "bound executable", meaning that it can run even on a machine with no Dyalog installed at all, although this would not make too much sense of course.
Have a look at the "launchy_manual.html" file which provides details. This file will be shown in your default browser by pressing F1 in Launchy or by selecting "Help > Help on Launchy" from Launchy's menu bar.
Pay attention to the INI file which should be self-explanatory for programmers.
