00:55 Design #1631: Use filesystem::path instead of string (packageDir, CoCoAManFileName)
The global @packageDir@ should probably also be of type @boost::filesystem::path@.
Currently it is @std::string@ a...

10:25 Design #1631: Use filesystem::path instead of string (packageDir, CoCoAManFileName)
It seems that @filesystem::path@ was introduced in C++17.

Just some suggestions.... maybe t...

Done for the CoCoA-5 menu. Anna Maria Bigatti
11:25 Feature #1526: EmacsUI: help/manual for selected string -- or just for word with cursor on?

What about the keybinding?

Website seems ok now.

John Abbott
10:23 Bug #1397 (Closed): Crashes if CoCoAHelp.xml is missing

18:57 Bug #1397: Crashes if CoCoAHelp.xml is missing
We probably need to change the fn @CoCoAManFileName@ (around line 950 in @OnlineHelp.C@).
The return type should be ...

23:26 Feature #1526: EmacsUI: help/manual for selected string -- or just for word with cursor on?
Is this something easy we could do quickly? Or is it better to postpone to the next release? John Abbott
23:24 Bug #1397 (Resolved): Crashes if CoCoAHelp.xml is missing
