Here is a very preliminary version of GNAT Studio 25.0wa as a stand alone app for macOS.
NEW:
The GNATStudio launcher looks for a gnatstudio_launcher.rc file in .gnatstudio folder from either $HOME or $GNATSTUDIO_HOME locations. If it exists, we can define some environment variables with the standard syntax VAR=VALUE. If the VAR exists then VALUE is append to it. If not, VAR is created with VALUE. Thus, it permits to set extra PATH to GNAT compiler and builder folders or GPR_PROJECT_PATH. If a line begins with ‘#’ then it is not considered. An example file of gnatstudio_launcher.rc is provided in the archive. Modify the content and put in your .gnatstudio folder.
See readme for details.
Limitation: Ada Language Server has some latencies and doesn’t respond when parsing source code with more 1000 lines. It may be due to some compilation options I missed.
There could be some other limitations that you might meet.
Feel free to report them here.
Any help will be really appreciated to fix these limitations.
