Mikolaj Wielgus ee6eeac6d8 egui: step through every band routing step, once per frame 
At last! We finally have that implemented without concurrency.

Mikolaj Wielgus da1438195a router: create new `Router` object, a wrapper over `Layout` 2024-06-28 14:46:15 +02:00
Mikolaj Wielgus 244367c4d7 router: rename `Router` to `Route` 
`Router`, soon to be written, will be a wrapper over `Board`.
 2024-06-28 01:12:37 +02:00
Mikolaj Wielgus 4fa97509e4 router: split out `Trace` to its own file and give it its own methods 
We'll be following this pattern:
* `Autorouter` - `Autoroute`,
* `Router` - `Route` (not yet done),
* `Tracer` - `Trace`.

Agent nouns (ending with -er) denote the object that holds large and
"unportable" parts of the state (such as `Board`, `Layout`, `Drawing`,
`Geometry`), while verbs (ending with -e) denote holders of other, more
"portable" parts of the state.

Mikolaj Wielgus 664bbee0b9 router: make `Astar` own the navmesh 2024-06-27 21:24:49 +02:00
Mikolaj Wielgus 0b3ebdbe3c router: make it possible for `Astar` to own its graph 
We aren't using this yet however because it requires a substantial
rearrangement of `Router`'s code.
 2024-06-27 15:07:58 +02:00
Mikolaj Wielgus 0419904b3f router: re-encapsulate graph in `Navmesh` and vertices in `VertexIndex` 
As in previous commit, this was done in the past, but I removed it when
improving `Navmesh` to hold each navvertex instead of calculating tem
during access.
 2024-06-26 22:34:59 +02:00
Mikolaj Wielgus 5254f768e5 router: implement (again) graph traversal traits for `Navmesh` 
These were implemented in the past, but I removed it when I made
`Navmesh` store each navvertex instead of calculating tem on the fly.
 2024-06-26 20:27:29 +02:00
Mikolaj Wielgus 114329a1ef router: don't store `&'a mut Layout` in `Router` 
First step towards removing multithreading in code in favor of stepping
over the routing process.
 2024-06-26 13:39:57 +02:00
Mikolaj Wielgus 43d84dc29e router: restore calculation of probe length (was temp. hardcoded to 0.0) 2024-06-26 00:47:16 +02:00
Mikolaj Wielgus 3fe305b99a sdl2-demo: fix compilation errors 2024-06-25 15:31:21 +02:00
Mikolaj Wielgus b6cfcc8518 router: don't panic if wraparound navvertex has no cw 
This may happen if target's guidecircle is in line of sight but its
center is not.
 2024-06-25 15:00:15 +02:00
Mikolaj Wielgus 3ce8cfcabc autorouter: fix redo operation 
Redone operation was only dispatched, not truly executed.

I've changed field names to avoid repeating this mistake in the future.

Mikolaj Wielgus c24d748bea autorouter: don't save in history until command is successfully finished 2024-06-20 12:14:51 +02:00
Mikolaj Wielgus ae2a862e0e router: store every vertex (fails tests but almost functional) 
Previously, rail vertices were not stored but generated on demand from
data stored in a `Triangulation<...>`. This functionality is removed in
favor of storing every vertex in `Navmesh`'s own graph built from the
`Triangulation<...>`, which is now afterwards discarded.

Tests still fail and rails aren't added yet, but this is close enough to
completion for me to commit so that I can now go to sleep without
worrying.
 2024-06-20 01:32:27 +02:00
Mikolaj Wielgus d4a310a5c0 graph: disambiguate naming of different kinds of indices 
Disambiguate between node indices and (teir inner) petgraph indices.
Rename "band index" to "band first seg index", as we identify bands by
teir first segs. Rename "trianvertex index" and "navvertex index"
respectively to "trianvertex node index" and "navvertex node index", as
these point to nodes on the geometry graph and only indirectly to
vertices on the vertex graph.

Mikolaj Wielgus 7f46d436af egui: fix sign of Y displayed on the bottom bar 2024-06-18 02:07:38 +02:00
Mikolaj Wielgus e15e1efe5e router: remove observers 
The observer "pattern", arguably, is an anti-pattern that managed to get
into textbooks. It causes a lot of problems, it was a bad idea to use
it.
 2024-06-18 01:37:45 +02:00
Mikolaj Wielgus d193ea6565 drawing: rename "segbends" to "canes" 
In addition to a seg and a bend, a segbend actually also contains a dot,
so let's rename it to "cane", which is also easier to translate.

Mikolaj Wielgus b09ffad9b3 autorouter: create new command for placing vias 
Undoing it is not implemented yet.
 2024-06-10 02:38:24 +02:00
Mikolaj Wielgus 6b6affb3fc autorouter: move autoroute command to its own file 
Since it accesses `Autorouter`'s fields, I made these `pub(super)`. This
feels unidiomatic, but let's give it a shot.
 2024-06-10 02:38:03 +02:00
Mikolaj Wielgus 5d082d81c0 layout: implement `MakePrimitiveShape` for vias 2024-06-09 21:29:03 +02:00

Mikolaj Wielgus 7a02877eb4 board,dsn: move layer and net name bidirectional lookup to `Mesadata` 2024-06-08 21:39:25 +02:00
Mikolaj Wielgus 98363fbfd1 drawing: remove unnecessary contracts on `&self` methods 2024-06-08 18:28:34 +02:00
Mikolaj Wielgus 19a4766cb5 board,dsn: introduce `MesadataTrait`, an extension of `RulesTrait` 
The trait's contents aren't implemented yet.

"mesa" is supposed to mean the opposite of "meta". By "mesadata" I don't
mean mere content or payload: I mean data that is stored *inside* or
*under* such content or payload.

I found this meaning of "mesa" -- as opposite of "meta" -- by browsing
somewhere on the internet. Fair chance many classicists would think
poorly of this usage. But I don't care about etymology: I just need a
word to close a lexical gap.

Mikolaj Wielgus 91480453b3 tests: add 3-pin XLR THT female to THT female test 
Hardly functional so far.

Tomasz Cichoń af1bb7069f dsn: add support of keepouts 
Includes some ugly hacks to get the deserializer to accept the relevant

Mikolaj Wielgus 86d2555b36 autorouter: accessibly store pin-pairs between which routed bands are 2024-06-05 20:26:23 +02:00
Mikolaj Wielgus 5eeeb5a004 autorouter: select nodes with pin-layer pairs, not only pins 
We call these pairs "selectors".

The command file format has been thus changed. I've upgraded the command
files in tests with the following command:

    jq ".done?.[].Autoroute |= {selectors: ([.pins.[] | {pin: ., layer: \"F.Cu\"}])}" $FILE | sponge $FILE

Where $FILE is the name of the upgraded command file.

Mikolaj Wielgus a80dfc10be autorouter,router: shorten and clarify terminology 
Rename "triangulation vertex" to just "trianvertex".
Rename "navigation vertex" to just "navvertex".

The standalone word "vertex" was overused and in some cases confusing.

Mikolaj Wielgus b22e3dce1a router,autorouter: stop hiding layout behind an arc-mutex 
This was preventing us from creating a new abstraction layer over

Mikolaj Wielgus dcbc5be5f3 router,autorouter: improve error handling 
Avoid unwrapping and use `Result<...>` instead as well-written code
should.

Mikolaj Wielgus 06150f5167 autorouter: don't cache nodes in `Selection` 
This solves the problem of having to use stateful deserialization.
 2024-05-23 20:00:43 +02:00
Mikolaj Wielgus 53fa89d02c egui: implement loading the history (not functional yet) 
Committing this non-functional and half-baked because loading the
history requires implementing stateful deserialization, which is quite
an effort to implement with Serde, as there are no applicable derive
macros.

Mikolaj Wielgus f03545124f autorouter: keep track of clicked pins 
Pin names provide us stable references that we can use to replay actions
later. We'll use this information to serialize the selection.
 2024-05-19 04:37:26 +02:00
Mikolaj Wielgus 530f81557a layout: keep track of node pins 
For the time being we're storing pin names in a hashmap with nodes as
keys. We need to know which node belongs to which pin because pins
provide stable identifiers for continents (connected components) that
we need for replayable command files.

Mikolaj Wielgus 83f3245e55 router: exclude same-net nodes from navmesh (except for start and stop) 2024-05-10 01:25:00 +02:00
Mikolaj Wielgus 91f9466d74 autorouter,router: route only single layer at a time 
It makes no sense to route multiple layers at once until we implement
automatic via placement, which is going to take a lot of time.

Mikolaj Wielgus 765738f44b autorouter: treat (layer, net) pairs like separate nets for ratsnest 
Most likely we won't be having via placement anytime soon, so let's
narrow our routing capabilities to single layer at a time.
