PTerm, the (only) terminal emulator for Pharo has been initially developed and maintained on Pharo 7. Due to some major API changes, PTerm was not compatible with higher version of Pharo such as 9 and 10. Porting it to Pharo 9 and 10 was long time in my to do list, but i didn't have spare time for such task. Fortunately, with the help of Kris, after many issues and pull requests, PTerm finally works on Pharo 9 and 10.
There are still some APIs that no longer works on Pharo 9 and 10 and needed to be ported, but major features of PTerm are now supported on these versions.
PTerm is available on Github at: https://github.com/lxsang/PTerm, the master branch is compatible with Pharo 9 and 10. Support for lower version (e.g. Pharo 7) is maintained on the pharo7-stable branch.
To try it on Pharo 9 and 10:
Metacello new repository: 'github://lxsang/PTerm'; baseline:'PTerm'; load
or on pharo 7
Metacello new repository: 'github://lxsang/PTerm:pharo7-stable'; baseline:'PTerm'; load
Again, thanks Kris for his contribution.
