I've finished the script I mentioned and put it on GitHub; it's called 'pharo-adjust-cursor'. https://github.com/tbrunz/installer_scripts It will edit the bash scripts that launch Pharo applications (i.e., pharolauncher, pharoiot, etc.) to either enable or disable enlarging the GUI pointer. This is useful on Linux systems with a 4K hi-DPI screen, since currently Pharo can enlarge its fonts and other GUI features, but not the cursor. (I don't have a Mac, so this is maybe not applicable to hi-dpi Macs.) The script can edit the Pharo application scripts "in both directions", to either enlarge the cursor or return it to normal size, depending on the option switch included on the command line. There are no side-effects caused by running the script multiple times in a row. Edits will create a backup file, with a name extension appended that reflects the script version backed up. Restoring a backup must be done manually. If run in a Pharo application directory (such as 'pharolauncher'), it will edit the scripts in just that directory. If run in a directory that contains one or more Pharo app directories, it will edit the scripts in each of them that it finds. (If neither situation is met, it will complain, and will complain if the expected Pharo bash scripts aren't found.) Comments & suggestions for improvements are welcome... -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
