Both were reproduced and both fixes verified, including +against a `--patch-module` simulation of the Windows condition. + +The `dist` profile now writes that manifest entry, and `JideLookAndFeelResolutionTest` guards +the classpath half - it fails if `WinLaF.jar` is dropped as apparent dead weight, which nothing +else would catch, since nothing names the class. + +What remains is the dependency itself. jide-oss 3.6.18 is from 2015, predates the module system, +and also reaches `sun.awt`, `sun.awt.windows`, `sun.awt.image`, `sun.awt.shell` and +`com.apple.laf`; those are exported pre-emptively so the next one reached is not a second bug +report. It is used for exactly one class, `ComboBoxSearchable`, to give combo boxes type-to- +search. Replacing that one behaviour would remove a 2MB dependency, the `WinLaF.jar` +system-scoped hack, and this entire class of failure. That is the real fix and it is not done. + +Note also that the version detection is stale: JIDE knows `os.version` 6.0, 6.1 and 6.2, so on +Windows 10 and 11 its own `isWindowsVistaAbove()` returns false. The crash arrives through the +`XPUtils` branch instead. Any workaround keyed on JIDE's idea of the OS would miss. + +### ~~`VariableTracker` is not published, so the project cannot be built from a clean checkout~~ (resolved: vendored) +**Was: severity high for contributors, none for users. Now resolved.** + +`pom.xml` used to declare `io.github.turtleisaac:VariableTracker:1.0-SNAPSHOT`, which existed in no +repository the build could reach and had no `` entry - only a local `~/.m2` copy and +one un-remoted clone. CI could not build this module, and neither could a new contributor. + +Resolved by **vendoring**: the `io.github.turtleisaac.variabletracker` package (models +`ScriptVariable`/`ScriptFlag`, the `VariableTracker`/`FlagTracker` Swing panels, hex cell helpers, +their `.jfd` forms, and the `variable_tracker/*.properties` resources) now lives under +`src/main/java` and `src/main/resources`, and the Maven dependency is gone. Its only third-party +needs - Jackson, FlatLaf, MigLayout - were already declared by PokEditor. A +`ScriptVariable(String, int)` constructor was added to satisfy `ScriptDocumentHighlightingTest`, +which the published artifact never had. + +### The field script editor is disabled +**Deliberate, not a defect.** It is the one editor that compiles scripts back into the ROM, +so a half-working version damages a project rather than merely disappointing. Its +construction is commented out in `PokeditorManager`; the subsystem and its 202 tests are +intact. + +### `CheckBoxEditor` turns anything that is not a Boolean into `false` +**Latent, not reachable today. Recorded because what keeps it unreachable is not obvious.** + +It holds no copy of the value it was opened with, so `getCellEditorValue()` reports the +checkbox's state whatever arrived: null, an Integer and a String all commit as `false`. Opening a +cell would change it - the same defect fixed in the combo box and numeric editors. + +Nothing reaches it. Every live CHECKBOX column reads an element of a `boolean[]` - the eight +Moves flags, the whole TM compatibility grid, Personal's FLIP - and the switch that serves them +covers every enum constant that maps to CHECKBOX, so the `return null` fallback below it is +unreachable for those columns. + +The part worth writing down is TM compatibility, where `getCellType` returns `CHECKBOX` for +**every** column, including the two frozen ones. The species-name column is a String with a +checkbox editor declared for it. That is harmless only because the frozen model overrides +`isCellEditable` to false - so a change making a frozen column editable would write `false` over +a species name, and nothing in the type declarations would suggest why. + +Not fixed rather than fixed speculatively: preserving the original value would hand null to a +write path that casts it to Boolean, so the fix is to stop the unconditional `getCellType` +claiming a type the column does not have, not to teach the editor to pass a value through. + +### `jokes.txt` has never been committed +`Main` reads `/pokeditor/jokes.txt`, which is in no commit on any branch. Startup no longer +dies without it, but the start screen shows nothing. The file is the project owner's +content and has not been invented. + +### Two sheets share one data list with independent models +Personal and TM compatibility are handed the same `List`. Row changes on one +leave the other's *selection model* holding an index the data no longer has, so a +subsequent `getValueAt` on that row throws. The row count itself is fine — `getRowCount` +delegates live to the model. + +Narrower than the name-bank problem above and largely self-healing on a repaint, but it is +the same shape: shared state, independent views. + +### The save confirmation does not name every file it writes +The dialog lists the files from the parser's declared requirements, which for Personal is +the personal NARC only. The same save also writes arm9, because preparing the data mutates +it. The dialog promises a complete list and omits the one file whose corruption is hardest +to recover from. + +### Reloading a sheet does not restore the name bank +`resetData` re-reads one data class. A row added or deleted beforehand has already changed +the shared `TextBankData`, which is not reloaded — so reload does not undo the edit. + +Fixing it needs care: `TextBankData` is one dirty flag for the whole application, so +reloading it wholesale would discard unsaved move, item and ability name edits made from +other sheets, silently, and then mark everything clean. + +### Dead code with no callers +`CsvReader`, `ArrayProcessor`, `XmlReader`, `BitStream`, `JarClassLoader`, `BitVector`, +`Directory`, `SheetExceptionFactory`, `JCheckboxTree`, `CircleButton` have no references in +`src/main`. They carry real defects — `XmlReader` tests for a close tag spelled with a +backslash and so cannot read well-formed XML at all; `ArrayProcessor` drops trailing empty +fields; `BitStream(0)` cannot grow — but nothing can reach them. Their tests are tagged +`dead-code`. + +The decision to leave them as-is is deliberate. The open question is whether to delete them +or revive them, not whether to fix them in place. + +### `DataManager` caches are process-wide with no reset +Static maps with no clear hook, which is why testing them needs reflection. They are scoped +to the ROM they were filled from, but nothing in the application can open a second ROM in +one session — the three menu entries that would are unimplemented and closing the tool +frame exits the process. The scoping is a guard against a future capability. + +--- + +## Nds4j — **this library is published to Maven Central, where a released version is permanent** + +### A scanned sprite is destroyed on save if its top-left pixel is not index 0 +**Severity: high. Live in the product.** + +The scanned NCGR decoder derives its decryption key from the first word of the *ciphertext*, +so a save/load round trip is only self-consistent when the first word of the *plaintext* is +zero. Edit the top-left pixel of a battle sprite, save, reload, and every row differs. + +Reachable through the sprite editor's import and its left/right swap. No format +compatibility cost to fixing it, so it can be fixed in a patch release — but it destroys +user work today. + +### The scanned NCGR path has no coverage that runs in CI +Every test touching a scanned image needs a retail ROM and skips without one. That is how an +8bpp under-allocation survived indefinitely and a 4bpp regression was introduced on top of +it with nothing going red. + +Worse, the one scanned test that exists is a re-parse comparison, and a re-parse **cannot** +detect a wrong decryption key: `save()` re-encrypts from whatever key the decode returned, +so seed and direction errors cancel exactly and produce garbage pixels with a byte-identical +round trip. Verified by experiment. + +A workflow appeared to cover this and never did. `maven-verify.yml` downloaded a ROM and ran the +full suite, but it moved the file into the workspace *before* `actions/checkout`, which cleans +untracked files and deleted it - and it ran on JDK 8, which cannot compile test sources using +`java.util.HexFormat`. Two independent faults, so the ROM suite has never run in CI here at all. +It obtained the ROM by reconstructing it with `xdelta3` against an empty source, meaning the +archive it fetched held the entire commercial game; that step is gone, and the workflow now takes +`-Drom.dir` so a runner with a legally obtained copy can point at one. Hosted runners have none, +so this gap stays open until such a runner exists or the fixture below does. + +The fix is a committed synthetic fixture with expected pixel values derived from an +independent implementation — DSPRE's decoder is separately written and agrees — asserting +decoded pixels rather than the round trip. + +### Cell banks of type 0 render at 8x8 and paste out of bounds +Type 0 NCER banks carry no bounding rectangle, so the cell image is sized from zeroes and +OAMs are pasted at raw, often negative, coordinates. + +The fix is to derive the bounds from the OAMs themselves. Two constraints make it less +obvious than it looks: the derived bounds have to reach `CellImage.save()`, which reads the +`Cell` fields directly, so keeping them local just moves the crash to the save path; and +writing them back is byte-neutral **only** for type 0, because the writer omits those fields +for that type. Triggering on a degenerate rectangle instead of on the bank type would +silently rewrite a stored field on a type 1 bank. + +A cell with no OAMs at all also needs a fallback — min and max over an empty set are +undefined. + +### Scanned 8bpp images can be read but never written +`save()` throws for scanned 8bpp. Anything round-tripping a NARC containing one loses it. +Shipping a read-only depth is a permanent asymmetry in the public API, and it cannot be +removed later without a behaviour change. + +The commented-out encoder appears correct — transcribed and run against the live decoder, it +reproduces the original ciphertext byte for byte in both scan directions. It needs its +buffer sized from the tile count rather than the pixel dimensions, as the 4bpp path now is. + +### `getNcerImage` uses a different placement convention from the rest of the class +A hardcoded 80x80 canvas with a centre origin, carrying a `//todo undo this being 80`. It +matches Tinke's renderer, so it is inconsistent rather than wrong, but two conventions now +coexist in one class. + +### `MemBuf` changed several published contracts in one release +`readByte()` returns unsigned where it returned signed; `readString` decodes ISO-8859-1 +where it decoded UTF-8; `writeString(s, len)` truncates where it threw; `skip` rejects a +negative count; `align` no longer pads an already-aligned buffer. + +Every in-tree caller normalises explicitly and so is unaffected, but these are behavioural +changes to a published surface and belong in the release notes. `align` is +format-visible — NARCs written after the change are not byte-identical to those written +before. + +Worth considering before the version is permanent: `readByte()` is now a duplicate of +`readUInt8()`, no signed byte reader survives, and the name contradicts +`DataInput.readByte()`. A deprecation and a clearly-named pair would cost nothing now and +cannot be done cheaply later. + +### `getEncryptionKey()` uses -1 to mean "no key" +`0xFFFFFFFF` is a legal key, so the sentinel is ambiguous in principle. In practice it is +unreachable: producing it requires a stream of 61,741 words — 246,964 pixels — which no DS +VRAM bank can hold. Recorded because the reasoning is not obvious, not because it needs +fixing. + +The real defect at those lines is that `save()` passes the sentinel through as a live seed +without checking. + +### Smaller items +- `Palette(int)` accepts any size; `Palette(Color[])` rejects more than 256. The first will + happily emit a 1000-colour NCLR. +- The NCGR parse constructor has no positive-dimension guard, so a 48-byte file yields a + zero-height image. +- `getSubImage` copies `scanMode` and `encryptionKey` onto a freshly laid-out image, where + neither applies. +- Sizing the scanned decode buffer from the tile count means a truncated file now fails with + "Not enough room to read" rather than a format error. It belongs in the malformed-input + suite. + +--- + +## PokEditor-Core + +### The parsers have no coverage that runs in CI +Round-trip tests against real game data need a retail ROM and skip without one. Of the tests +that do run, most assert only that a parser is non-null. **A green build here says very +little**: no format's parse is exercised. + +Run with `-Drom.dir=` before trusting a change to a parser. Expect failures — the +round-trip assertions were strengthened, and the original author's own code counted "valid +but non-1:1 matching" script files, which suggests scripts do not round-trip byte-exactly. + +### `isEndCommand` treats `endstd` as terminating a run +An unannounced change to script traversal. If it is wrong, commands after an `endstd` are +never visited and are silently dropped on save. The macro file documents command 21 as +"Yield to parent context", so it is probably right — but it is the most consequential line +in the script reader and it is unverified against a real ROM. + +### Abort-versus-tolerate is unresolved on the text and script load paths +`TextBankData` bounds checks and `offsetObtainer` now abort where they previously degraded. +For a retail ROM this is fine. For a hacked ROM — which is the population this tool +serves — it converts a file that opened with one garbled entry into a file that will not +open at all. + +The same question was already settled the other way for evolution files, where a cap fixed +at the retail entry count made expanded tables unsavable. These two paths should be +consistent, and currently are not. + +--- + +## Nds4j-ToolUI + +### Only the file helper is tested; the module's actual job is not +**Severity: this is where the three items below live.** + +3,834 lines of `src/main` against 588 of tests, and the tests reach two files: `FileUtils` and +the hexadecimal spinner's formatting. `Tool` (1,299 lines) has none, nor do `ToolFrame`, +`PanelManager`, `ProjectCreateDialog`, `ProjectStartPanel` or `ThemeUtils`. + +That is the module owning project open and save, the save lock, and the git integration - and the +three defects below are all in `Tool`, `ToolFrame` and `PanelManager`, which is not a +coincidence. `FileUtils.atomicWrite` was the one part with tests, and it is the one part that got +fixed properly, because the tests could show what was wrong. + +Worth stating precisely, because the raw numbers mislead in the other direction: the atomic-write +tests are genuine. Three of them turn on POSIX permissions and skip when the suite runs as root - +which is what a container does, so a local run reports `25 passed, 3 skipped`. Hosted runners are +not root, and CI reports `25 passed, 0 skipped`. Those three are the ones with teeth: they are +what proved the previous durability test asserted nothing. + +### ~~The backup commit failed for anyone who signs commits with SSH~~ - fixed +`gpg.format = ssh` in a user's global config made JGit refuse the repository, with an unchecked +`IllegalArgumentException` that escaped the worker's handlers and reached the user as "an +unexpected error occurred" after **every save**. The save had worked; only the backup was missing, +and nothing distinguished the two. + +Needed both a bump to JGit 7.1.0 and an explicit `setSign(false)` - on 6.7 and 6.10 the commit +throws whatever `setSign` says, and on 7.1 it throws unless signing is explicitly off. Signing an +automatic local backup was never meaningful anyway. + +PokEditor also declared JGit itself, at 6.7.0, and a direct dependency beats a transitive one - so +upgrading ToolUI alone would have left the shipped application unchanged. That declaration is +removed rather than bumped: nothing in PokEditor references JGit, and pinning it again is how the +versions drift apart in the first place. **Let ToolUI own this version.** + +The general lesson is worth more than the fix: no test had a repository configured the way a real +user's is. It surfaced only because this container happened to have that setting. + +### ~~A multi-file save is not atomic~~ - fixed, with a named remainder +`FileUtils.atomicWrite` is split into staging and the rename it ends with, and `atomicWriteAll` +stages every entry before moving any of them. `Tool.SaveBatch` collects sections and writes them +as one; PokEditor's sheet save is now a single batch. + +Staging is where a save actually fails - a full disk, a read-only file, a bad path - so those now +happen while every target is still the old version. + +**What is not fixed**, and the javadoc says so rather than claiming otherwise: the run of renames +at the end is not one operation. Each is atomic alone, but a process killed between two of them +still leaves some files new and some old. Closing that needs a journal and a recovery pass on +open, which would be the next step if it is ever wanted. + +### ~~Nine `writeModified*` methods document a boolean they cannot return~~ - fixed +They return `void` and throw. `writeProjectInfo` keeps its boolean, which has always meant +something. This is a source-breaking change for any caller testing the result, which is why it was +worth doing before 1.0.0 rather than after. + +### ~~The git worker holds the save lock for the duration of a commit~~ - fixed +Held across staging only. The reason recorded here for holding it - that a partially written file +could be committed - was **wrong**: files are written through a temporary and renamed, so no file +is ever visible in a partial state. The real reason is that a save landing mid-staging commits +some files new and some old, and that reason justifies staging but not committing. + +A save that still has to wait now waits a bounded time and says why, instead of freezing the +interface with nothing said. That is a mitigation, not a cure: saving still happens on the event +thread, and moving it off is the actual fix. + +--- + +## Dependency declarations + +Swept after the JGit pin turned out to be a class of problem rather than one mistake. The rule +that came out of it: **a module declares what it imports, and nothing else.** Both halves were +being broken. + +*Declaring what is not used* - a direct declaration overrides what an upstream dependency asks +for, and since nothing imports it, a wrong version cannot fail to compile. JGit was this, and +shipped broken. Also removed: `jsvg` from ToolUI and PokEditor, which belongs to flatlaf-extras +and was pinned one version ahead of what flatlaf asks for; `flatlaf-intellij-themes` from ToolUI, +which never referenced it - `ThemeUtils` holds an empty list and the consumer supplies themes; +`jackson-dataformat-xml` from all three; `junit:junit` from Core and PokEditor, both entirely on +JUnit 5. + +*Using what is not declared* - the same sweep proved why this matters. Removing +`jackson-dataformat-xml`, which nothing imported, also removed the only route to +`jackson-databind`, which several modules do import, and the build stopped compiling. +`jackson-databind` and `jackson-core` are declared explicitly now. + +Guice moved to test scope in Core, where nothing in `src/main` imports it. + +Two things worth keeping in mind for the next sweep: + +- **`dependency:analyze` is a report, not a verdict.** It reads bytecode, so it called `jsvg` and + `flatlaf-intellij-themes` unused in PokEditor, which genuinely uses both - through runtime + loading it cannot see. Every entry above was checked against the source. +- **A dependency change proves nothing without `clean`.** The first pass here reported a green + build on stale `target/classes`: the poms had changed but no source had, so nothing was + recompiled. The clean build failed immediately. + +### The remaining hazard, unfixed +`Nds4j` is declared at `1.0.0` in three poms, and `assertj` and `junit-jupiter` in all four. +Nothing disagrees today - every shared artifact was checked - but there is no parent pom or +`dependencyManagement`, so each is a place the versions can drift apart silently. That drift, +already happened, is what the JGit bug was. + +--- + +## Building and releasing + +### What is published, and what is not +| Artifact | Version | On Central | +|---|---|---| +| `Nds4j` | 1.0.0 | **yes** - jar, pom, sources, javadoc and `.asc` all resolve | +| `Nds4j-ToolUI` | 1.0.0 | no - 404 | +| `PokEditor-Core` | 1.0.0 | no - 404 | +| `PokEditor` | 3.2.0 | n/a - an application, not a library | + +Nds4j 1.0.0 is **permanent**. A published coordinate cannot be replaced, which is why the +Nds4j section above is stricter about its API than the other three. + +### Building the chain from a clean checkout +Only Nds4j resolves on its own. ToolUI and Core have to be installed locally before PokEditor +can compile, in dependency order: + +``` +mvn -q install -DskipTests -f Nds4j/pom.xml # only if you changed it +mvn -q install -DskipTests -f Nds4j-ToolUI/pom.xml +mvn -q install -DskipTests -f PokEditor-Core/pom.xml +mvn verify -f PokEditor/pom.xml -DexcludedGroups=dead-code +``` + +Nds4j's line is optional because 1.0.0 comes from Central. Include it when testing a change to +Nds4j against its consumers - installing a snapshot locally is now the way a cross-repository +change gets exercised end to end, and it is a better test than CI ever ran, because it exercises +the exact combination about to ship rather than whichever branches happened to share a name. + +**`-DexcludedGroups=dead-code` is not optional on PokEditor.** Without it the build goes red: +545 tests run, 17 of them fail, and every one of those 17 is a `@Tag("dead-code")` specification +that is *expected* to fail - the header of this file explains why they exist. With the exclusion +it is 528 passing and green. CI passes the same flag, which is why CI is green and a plain +`mvn verify` is not. Anyone following these steps without it will conclude the build is broken. + +From a cold local repository: the two sibling installs take about 25 seconds together, and +PokEditor's own `verify` about 17 more. + +### CI resolves Nds4j from Central rather than building it +ToolUI's and Core's workflows used to resolve a branch of the same name, clone Nds4j and install +it from source. That is removed. Once Nds4j was published and both modules pinned `1.0.0`, the +steps no longer affected what the build resolved; and once Nds4j's `main` moved on they installed +a coordinate nothing asks for, so the jar they built was discarded. CI now tests against the same +artifact a consumer downloads. + +The cost is real and is worth stating: **CI can no longer exercise a change that spans two +repositories.** Picking up new Nds4j behaviour means editing the version pin, which is a +reviewable line in a diff instead of an implicit consequence of a branch name; the combined test +moves to a local checkout of all four, as above. + +PokEditor's CI still builds **ToolUI and Core** from source, because neither is published and +there is no other way for it to resolve them. Nds4j is still in that loop and no longer needs to +be - a one-word change, not yet made. + +### A version bump propagates by hand +`Nds4j` is pinned at `1.0.0` in three poms. Nothing updates them automatically, and with the CI +source-builds gone nothing disagrees loudly either, so a bump is now three deliberate edits. + +Nds4j `main` currently declares `1.0.0` while sitting **8 commits past the `v1.0.0` tag**, having +gained `CellAnimation`, `Screen` and a rewritten `CellBank` since the release - so the name +"Nds4j 1.0.0" presently refers to two different jars. An open PR moves `main` to +`1.1.0-SNAPSHOT`, with a test asserting that an in-development version carries a qualifier. Until +it merges, a local `mvn install` of Nds4j `main` silently overwrites the published 1.0.0 in the +local repository with different code, which is the failure mode worth knowing about when +following the local build steps above. + +### Publishing +**Nds4j** publishes through `release.yml`, triggered by a tag. It has run once, on `v1.0.0` +(`ad9c08a`), and succeeded. The signature on Central is the evidence that the four repository +secrets exist and the signing key works - an earlier version of this file listed both as +outstanding prerequisites, and both were cleared by that run. An earlier version also claimed +publication was a prerequisite for merging, which was never true: nothing in CI resolved these +from Central at the time. + +**ToolUI and Core have no publishing path at all.** Neither has a `release.yml`, a +`central-publishing-maven-plugin`, a `maven-gpg-plugin` or a `maven-javadoc-plugin`, and neither +pom carries any of ``, ``, ``, ``, `` or `` - +all of which Central requires. This is an open decision rather than a defect: ToolUI is a library +other people are invited to build tools against, so it has a real case for being published; Core +is PokEditor's own data layer with no independent consumers, so it has much less of one. Until +either is decided, both stay source-built by whoever needs them. + +### ~~PokEditor's build is red and will stay red~~ - resolved +Every run used to fail at *Verify dependencies resolve*, on the unpublished `VariableTracker`, +skipping every later step including the jar build. Resolved by vendoring, as recorded above. + +### ~~Open decision blocking a permanent API~~ - settled +`CodeBinary.compressed` was private, had no getter, and was read nowhere - which is how it +carried an inverted value undetected. It is now public as `wasCompressed()`, and its tests ask +the object rather than reaching in by reflection. + +Past tense because the flag describes the data the binary was **constructed from**, not what it +holds now: the buffer is decompressed either way and `getSize()` is the decompressed length, so a +retail arm9 answers `true` while everything read out of it is plain. + +It went in as `isCompressed()` first, and that was wrong twice over. `Overlay` extends +`CodeBinary` and already has an `isCompressed()` - the compression bit the ROM's overlay table +stores, a different fact and a settable one - so the new method was silently overridden. Same +signature, no `@Override`, nothing from the compiler, and a `CodeBinary` reference to an +`Overlay` quietly answering the other question. The two can disagree, and a test now pins that +they do. Worth remembering as the shape of the risk: adding a name to a base class can capture a +subclass's existing method without a word from the compiler. diff --git a/pom.xml b/pom.xml index ad9e965..7669055 100644 --- a/pom.xml +++ b/pom.xml @@ -6,7 +6,7 @@ io.github.turtleisaac PokEditor - 3.0-SNAPSHOT + 3.2.0 20 @@ -15,18 +15,22 @@ + + + com.fasterxml.jackson.core + jackson-databind + 2.15.2 + + org.junit.jupiter junit-jupiter 5.9.2 test - - junit - junit - 4.13.2 - test - org.assertj assertj-core @@ -54,12 +58,6 @@ 3.2.1 - - com.github.weisj - jsvg - 1.2.0 - - com.miglayout @@ -74,19 +72,6 @@ 3.6.18 - - - org.eclipse.jgit - org.eclipse.jgit - 6.7.0.202309050840-r - - - - com.fasterxml.jackson.dataformat - jackson-dataformat-xml - 2.15.2 - - com.google.inject guice @@ -105,27 +90,24 @@ io.github.turtleisaac Nds4j - 0.1.0 + 1.0.0 io.github.turtleisaac PokEditor-Core - 1.0-SNAPSHOT + 1.0.0 io.github.turtleisaac Nds4j-ToolUI - 1.0-SNAPSHOT - - - io.github.turtleisaac - VariableTracker - 1.0-SNAPSHOT + 1.0.0 + - + io.github.turtleisaac WinLaF @@ -133,6 +115,144 @@ system ${project.basedir}/WinLaF.jar + + + org.junit.jupiter + junit-jupiter + 5.9.2 + test + + + org.assertj + assertj-core + 3.24.2 + test + + + + + org.apache.maven.plugins + maven-surefire-plugin + 3.2.5 + + + -Djava.awt.headless=true --add-opens java.desktop/java.awt=ALL-UNNAMED + + + + + + + + + dist + + + + + org.apache.maven.plugins + maven-antrun-plugin + 3.1.0 + + + unpack-winlaf + prepare-package + run + + + + + + + + + + + + org.apache.maven.plugins + maven-shade-plugin + 3.5.2 + + + package + shade + + false + true + dist + + + *:* + + META-INF/*.SF + META-INF/*.DSA + META-INF/*.RSA + module-info.class + + + + + + + io.github.turtleisaac.pokeditor.Main + + java.desktop/com.sun.java.swing.plaf.windows java.desktop/sun.awt java.desktop/sun.awt.windows java.desktop/sun.awt.image java.desktop/sun.awt.shell java.desktop/com.apple.laf + + + + + + + + + + + + \ No newline at end of file diff --git a/src/main/java/io/github/turtleisaac/pokeditor/DataManager.java b/src/main/java/io/github/turtleisaac/pokeditor/DataManager.java index 6bcd2f6..917b11d 100644 --- a/src/main/java/io/github/turtleisaac/pokeditor/DataManager.java +++ b/src/main/java/io/github/turtleisaac/pokeditor/DataManager.java @@ -44,6 +44,8 @@ import java.lang.reflect.ParameterizedType; import java.util.HashMap; +import java.util.Objects; +import java.util.HashSet; import java.util.List; import java.util.Map; import java.util.Set; @@ -63,7 +65,8 @@ public class DataManager { List textData = DataManager.getData(rom, TextBankData.class); List data = DataManager.getData(rom, PersonalData.class); - DefaultSheetPanel sheetPanel = new DefaultSheetPanel<>(manager, new TmCompatibilityTable(data, textData)); + List moves = DataManager.getData(rom, MoveData.class); + DefaultSheetPanel sheetPanel = new DefaultSheetPanel<>(manager, new TmCompatibilityTable(data, textData, moves)); // String[] moveNames = textData.get(TextFiles.MOVE_NAMES.getValue()).getStringList().toArray(String[]::new); // sheetPanel.thing(new ComboBoxCellEditor(moveNames)); return sheetPanel; @@ -130,9 +133,65 @@ public static GenericParser getParser(Class eC private static final Map, List> dataMap = new HashMap<>(); private static final Map codeBinaries = new HashMap<>(); + /** + * The ROM the two caches below hold data for. + *

    + *
  • Downward propagation. Checking a node checks its entire subtree; unchecking it + * unchecks the entire subtree. The operation is a subtree-wide constant function.
    • + *
  • Upward consistency. A node is CHECKED iff all of its children are CHECKED, + * UNCHECKED iff none of its descendants are checked, and PARTIAL otherwise.

    • + *
  • Leaves are two-state. A node with no children has no partial state to be in.
    • + *
  • Locality. An operation inside one subtree changes nothing in a sibling subtree.
    • + *
  • Idempotence. Repeating an operation changes nothing anywhere.
