This is a bit of an omnibus commit, apologies for that. This commit
moves Keyman Developer to a proper multi-process model, where editing
files from multiple projects is handled much more cleanly, with each
project loaded in a separate process.
Files that are edited outside of a project structure are loaded into a
'temporary project' in a single process, which provides a pathway for
existing users who may have legacy files outside the normal Keyman
Developer project model.
There are several components to this:
1. Inter-process communication (Multiprocess, CopyDataHelper units and
multiprocess test project). These modules establish a method of
enumerating running Keyman Developer instances (with EnumWindow),
recording relevant metadata for each instance (by thread id) in the
registry (registry used because it manages contention without
additional effort from us), and communicating between processes with
WM_COPYDATA.
2. Command-line parsing (TikeCommandLine). Determines project ownership
(ProjectOwningFile) for each filename passed on the command-line, and
passes these over to existing instances of Keyman Developer that have
that project loaded, or starts new instances as needed.
3. Temporary project management. Mostly in ProjectUI.
Also, moved GlobalProjectStateWnd management out of ProjectFile.pas and
into Project.pas, alongside other global project variables.
A follow-up will add functionality to determine if a file opened within
the Keyman Developer UI should open in the same instance or in a
separate instance (see TfrmKeymanDeveloper.OpenFileInProject). This will
use the same methodology as TikeCommandLine does now, so may involve
further refactoring.
This commit establishes the idea of 'keyman.kpj' as a future default
filename for Keyman Developer projects, but does not enable it, in
ProjectOwningFile. It is planned to introduce this fixed filename in
version 18.0 (see #10113).
Fixes#9869.
Adds a 'Description' field, tweaks Copyright strings, and tweaks
default content for documentation to the New Project wizards and
kmconvert.
Fixes#9551.
Removes various .keyboard_info files from test fixtures and also removes
generation of .keyboard_info source files from kmconvert, alongside now-
redundant tests (cvt.dpr).
Adds license file to .kps, kmp.json, kmc-package, package editor, and
new project templates. The intent is for LICENSE.md to be the file used,
and for any keyboards on keymanapp/keyboards, it should always be a
standard MIT license.
Fixes#2803.
The new basic project template will now include a default icon,
generated either from the first BCP 47 tag, or else from the first 3
letters of the filename of the keyboard.
The icon will not be included if the keyboard does not target desktop
platforms, as web/touch do not currently support the icon.
