fmtlib uses consteval format string processing, which makes it more
efficient than std::snprintf().
snprintf()s in libuv, mpack, processstarter, and wpigui were left alone.
processstarter uses stdlib only, and wpigui only depends on imgui.
fmt::format_to_n() is analogous to std::format_to_n()
(https://en.cppreference.com/w/cpp/utility/format/format_to_n)
wpi::format_to_n_c_str() is a wrapper which adds the trailing NUL.
Limiting with vsync is apparently unreliable on a number of systems;
this resulted in high CPU/GPU usage.
Also add current actual frame rate to about dialog of GUI tools.
Storage is now nested.
Separate "roots" can be configured which save to separate files.
In particular, this is used to save wpigui and ImGui window position
to a -window.json file.
ImGui's ini (for window position) is mapped to JSON.
You can optionally specify a directory to load from on the command line.
If one isn't provided, it uses the global system directory.
Any changes made are automatically saved here.
Workspace | Open: select directory, the current layout is replaced with that
workspace, and future auto-saves also switch to that location. The main
window size/location is not changed, only the contents.
Workspace | Save As: select directory, the current layout is saved there,
and future auto-saves also switch to that location.
Workspace | Reset: window locations are preserved, but all other settings
are reset to default (including e.g. removing plot windows). This will also
end up clearing the current save file. as with load, the main window
size/location is not changed.
Workspace | Save As Global: "save as" to the global system location
Notably, the main window size/location is only loaded at startup, but is
auto-saved as part of the current workspace.
- Twine, StringRef, Format, and NativeFormatting have been removed
- Logging now uses fmtlib style formatting
- Nearly all uses of wpi::outs/errs have been replaced with fmt::print() or
std::puts()/std::fputs() (for unformatted strings).
- A wpi/fmt/raw_ostream.h header has been added to enable
fmt::print() with wpi::raw_ostream
This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
This reuses many pieces of the current simulation GUI. The common pieces have
been refactored into the libglass library.
The libglass library is designed to be usable for other standalone data
visualization applications (e.g. viewing data logs).
The name "glass" comes from "glass cockpit", as the application features
several multi-function displays that can be adjusted to display robot
information as needed.
