What the plan tool was missing was not geometry but the ordinary business of
editing: taking a mistake back, dividing what is drawn, and seeing what the next
click will do before making it.
Cofanie. The document is plain data, so a step is a copy of it. What counts as one
step is decided by watching the document - a fingerprint over the tracks, turnouts
and catalogue - rather than by dressing every edit with a call: a frame that
changes anything opens a step, and the step closes when the drawing settles. That
is what makes a drag, or a number typed digit by digit, one step and not thirty,
and nothing can be forgotten on the way in. Ctrl+Z / Ctrl+Y; the scene editor
listens for the same keys, so it hands them over while the plan has the keyboard.
Złącze i wycięcie. `insert_joint` divides whichever element a station lands in and
leaves one chain: the ground does not move, the curvature at the new joint is the
one that was always there, and the fit reads the chain the same way afterwards. It
is refused on a straight, because two straights end to end are one straight and the
skeleton will not read that, and under a turnout, which is one piece of geometry on
one element. `cut_track` takes a piece out and does leave two tracks - a gap is the
ground between them, not a hole in a chain.
Przejście rozjazdowe. A turnout may now stand against another one: where it stands
is then worked out from that one's frog, not authored, so moving either carries the
other with it and a trapez stays shut. The frog has to land on the line leaving the
other frog - not on the track's axis, which is 1,469 m further on for a 1:9 - so
the station is settled by laying the turnout and walking it along until it does.
Drawing is a tool now, not what a click happens to do: until Rysuj is on, a click
picks what is under it. With it on, the cursor at the growing end shows the corner
and the straight the next click would lay, worked out by the same fit_corner the
click itself uses. A chain only grows at a loose end, and the first element of a
track is put down by two clicks instead of landing on the plan's zero.
Also here: the curvature strip under the panel, pikietaż in the rows and at the
cursor, how far the laid axis runs from the clicks it was drawn from, the file
format saying which frame and which units it is in (v9), plans chosen from the
directory instead of typed, and editor/samples/demo.m0s - two parallel tracks and a
trapez - with the generator that wrote it and a test that opens it and demands it
lays clean.
The editor branch was written against headers and the PCH, both of which this
branch has done away with, so its own files were ported rather than merged: the
five headers it added are now interface units and their .cpp files module
implementation units.
- editor/{puwg1992,polandmap,turnouts,orthophoto} become eu07.editor.* modules,
application/planpanel becomes eu07.application.planpanel. The plan tool keeps
to its own module rather than joining the eu07.simcore partitions: it stands on
the editor's libraries and eu07.application.uilayer, not on the simulation core,
so :editoruilayer can export import it without a cycle.
- glm arrives by import eu07.glm, never by include, as the rest of the tree does.
maj0sted is header-only and glm-free, so its headers stay includes in the global
module fragment - every unit that names those types includes them itself, since
a global fragment is not visible across units.
- the one textual conflict was :editoruilayer's include block against this
branch's imports; resolved this branch's way plus the planpanel import.
Builds with clang 22 (-DWITH_BETTER_RENDERER=OFF) and starts into the editor on
empty ground with -editor alone.
AnimModel.cpp reaches cParser through the simulation core, not a direct
import, so the previous pass missed it; the propagation now follows the
whole import closure. Train.cpp, drivermode.cpp and Globals.cpp call
Console:: inside _WIN32 guards without importing eu07.console - invisible
on Linux, where those blocks are skipped.
A template defined in a module interface is instantiated in the importing
unit, where its body's types must be complete. A declaration reaching the
importer only through the interface's global module fragment is not
enough for MSVC: cParser::operator>> uses std::stringstream, and every
unit that parsed a float got an incomplete type.
526 headers across 161 units, derived from what each interface's template
bodies actually name.
A "Plan" panel, opened from Track layout in the editor's menu bar, draws a
niweleta the way the web frontend did: click to lay chained straights, drag
a corner to move it, and pick a fit for each gap between them. The geometry
is entirely maj0sted's - the panel gathers the input, hands the document to
solve_project and paints the rails that come back, coloured by whether they
came from a straight, an arc or a clothoid. Scenery nodes are untouched.
A fit the library cannot produce is simply absent from its answer, so the
gap is labelled as not fitting rather than left looking as though its
parameters took effect. Save/load go through the library's own document
format, so a project written here opens in the same state.
Also translates the comments added with -editor into English, matching the
files they sit in.
