fix(themes): keep generated keys when a nested theme variable is partly overridden - #8300

…ly overridden
Every theme copies the user's overrides onto itself twice, once before
updateColors() and once after it, so that an explicit value beats a
derived one. The second copy was a plain assignment. For an object-valued
variable that replaced the whole object the theme had just generated with
the few keys the user gave, so
themeVariables:
xyChart:
titleColor: '#ff0000'
left xyChart with one key instead of thirteen. xychart, cynefin, radar and
wardley then fill the gaps from theme-default rather than from the active
theme, so on the dark theme that one override turned the chart's
background white and its text #131300.
The second pass now merges an object-valued override into the generated
object, and still replaces every other value as before. The docs already
present one-key overrides like the one above as the way to use these
variables.
Of the three e2e fixtures that override a nested variable, only
should-render-cynefin-with-theme-override renders differently: its
textColor and labelColor now come from the base theme it asks for
instead of from theme-default (#131300 becomes #0b0b0b).
Closes mermaid-js#8299

There was a problem hiding this comment.

Thanks @filipsajdak, this is a tidy fix for a bug that is easy to hit. The dark-chart-turns-white repro in #8299 made the problem immediately clear. 🙏
What's working well
- 🎉 [praise] The fix has exactly the right scope.
applyOverrideonly changes the second override pass, and only when both sides are plain objects. Scalars, strings and arrays (e.g.bkgColorArray) behave exactly as before. I checked every object-valued variable the themes generate (xyChart,radar,wardley,cynefin,packet). All are flat, so a one-level merge is complete. - 🎉 [praise] One shared helper instead of 11 copies of merge logic, and the change in each theme is a single line. All 11 themes registered in
themes/index.jsare covered. - 🎉 [praise] The spec genuinely proves the bug. It derives its cases from what each theme actually generates, so new object-valued variables are covered automatically. I ran it against
develop's theme files and got 29 failures (the 28 theme/variable pairs from the description plus the darkxyChartcase). On this branch it passes. - 🎉 [praise] The before/after SVG comparison with a byte-identical control render is excellent evidence. The one expected visual change (cynefin now takes
textColor/labelColorfrom thebasetheme it asks for) is correct behaviour.
Verification
- Theme, config, mermaidAPI, and xychart/radar/cynefin/packet/wardley unit tests: 392/392 passing locally.
- CI is fully green, including all e2e shards and Argos.
- Merges cleanly with
develop, and nothing inthemes/has changed ondevelopsince the merge base.
Security
No XSS or injection issues introduced. The object spread defines keys as own properties, so an own __proto__ key doesn't reach the prototype setter. Directive/frontmatter input is also key-filtered by sanitizeDirective before it reaches the themes. User values reach the styles exactly as they did before; the only extra values kept are ones the theme generated itself.
Things to address
- 🟢 [nit]
theme-nested-overrides.spec.ts:19-21: theObject.hasOwnfilter is only there to narrow the type, sinceObject.keysalready returns own keys.Object.keys(themes) as (keyof typeof themes)[]would read more directly. Entirely optional.
Nothing blocking. Approving. Let's get this in. 🚀

Upstream release: https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4012.1.0 Release notes: ### Minor Changes - [#8303](mermaid-js/mermaid#8303) [`9140716`](mermaid-js/mermaid@9140716) Thanks [@filipsajdak](https://github.com/filipsajdak)! - feat: add the `elk.orientFeedbackEdges` option, enabled by default. With the ELK layout, an edge from a node that a subgraph feeds back into that subgraph is now routed downstream instead of around the subgraph. This changes the layout of existing ELK diagrams that contain such edges; set `elk.orientFeedbackEdges: false` to keep the previous routing. - [#8250](mermaid-js/mermaid#8250) [`fd4f5f2`](mermaid-js/mermaid@fd4f5f2) Thanks [@kartben](https://github.com/kartben)! - feat: add a `bitOrder` option to packet diagrams. It defaults to `ascending`, which is the current behaviour, and `descending` mirrors every row so it reads from that row's highest bit down to its lowest. Fields are still declared lowest bit first and keep their width, so switching a diagram between the two conventions only means changing `bitOrder`. ### Patch Changes - [#8330](mermaid-js/mermaid#8330) [`50c9e55`](mermaid-js/mermaid@50c9e55) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: upgrade chevrotain to 13 so mermaid no longer pulls in vulnerable `lodash-es@4.17.23` - [#8259](mermaid-js/mermaid#8259) [`4c90f5c`](mermaid-js/mermaid@4c90f5c) Thanks [@afonsojanu](https://github.com/afonsojanu)! - fix(sequence): allow whitespace between an actor name and its `@{ ... }` config object `participant Bob@{ "type" : "database" }` parsed fine, but adding a single space before the config object (`participant Bob @{ "type" : "database" }`) failed with a confusing parse error, even though the plain form without a config object tolerates trailing whitespace just fine. - [#8339](mermaid-js/mermaid#8339) [`c7fa1a5`](mermaid-js/mermaid@c7fa1a5) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: keep ELK class-diagram cardinalities off namespace frames - [#8334](mermaid-js/mermaid#8334) [`d67331d`](mermaid-js/mermaid@d67331d) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix(class): place cardinality labels beside their relation ends on dagre's sides with ELK, centre dagre's end labels, and stop clipping their text - [#8344](mermaid-js/mermaid#8344) [`99a050b`](mermaid-js/mermaid@99a050b) Thanks [@pbrolin47](https://github.com/pbrolin47)! - fix: with the ELK layout, an edge label could sit up to 16px beside its edge instead of centred on it, when the edge's terminal jog was straightened after the label's position was computed. The label is now re-projected onto the straightened route - [#8276](mermaid-js/mermaid#8276) [`3101c7d`](mermaid-js/mermaid@3101c7d) Thanks [@mir-ashiq](https://github.com/mir-ashiq)! - fix(error): show the actual error message in the error diagram When a diagram fails to parse, the error diagram now draws the real error message below the "Syntax error in text" headline, wrapped to at most four lines. Hosts that only show the SVG (GitHub, GitLab, Obsidian, exported images) no longer hide what actually went wrong, e.g. that the flowchart edge limit was exceeded and `maxEdges` needs raising via `mermaid.initialize`. - [#8296](mermaid-js/mermaid#8296) [`aa29345`](mermaid-js/mermaid@aa29345) Thanks [@pentaoa](https://github.com/pentaoa)! - fix: preserve explicit source relations on event modeling reset frames - [#8297](mermaid-js/mermaid#8297) [`967bbde`](mermaid-js/mermaid@967bbde) Thanks [@pentaoa](https://github.com/pentaoa)! - fix: reject duplicate event modeling frame IDs before rendering - [#8337](mermaid-js/mermaid#8337) [`147f343`](mermaid-js/mermaid@147f343) Thanks [@knsv-bot](https://github.com/knsv-bot)! - fix: a flowchart that declares the same subgraph id more than once now renders as one merged subgraph with the ELK layout instead of producing NaN geometry. Classes and `view: collapsed` set on a repeated subgraph now apply to it, whichever declaration they follow. - [#8203](mermaid-js/mermaid#8203) [`40ef7b4`](mermaid-js/mermaid@40ef7b4) Thanks [@MFA-G](https://github.com/MFA-G)! - perf(frontmatter): replace the quadratic front matter regex on hot paths `frontMatterRegex` backtracks polynomially on whitespace-heavy input, so a diagram well inside the default `maxTextSize` could stall parsing for over a second. `detectType` and `extractFrontMatter` now use a linear scanner that matches the regex result exactly, leaving no document stripped differently. - [#8254](mermaid-js/mermaid#8254) [`351d7d2`](mermaid-js/mermaid@351d7d2) Thanks [@galshir](https://github.com/galshir)! - fix: warn when a gantt task references an unknown `after`/`until` task id, or when its end value is neither a valid date nor a valid duration - [#8249](mermaid-js/mermaid#8249) [`b657a2c`](mermaid-js/mermaid@b657a2c) Thanks [@mir-ashiq](https://github.com/mir-ashiq)! - fix(sequence): allow hyphenated actor and participant names when a config object is attached - [#8300](mermaid-js/mermaid#8300) [`c38a565`](mermaid-js/mermaid@c38a565) Thanks [@filipsajdak](https://github.com/filipsajdak)! - fix: A partial override of an object-valued theme variable such as `xyChart`, `radar` or `cynefin` keeps the values the theme generates for the keys it leaves out - [#8333](mermaid-js/mermaid#8333) [`8afd83c`](mermaid-js/mermaid@8afd83c) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: upgrade the parser to langium 4.4 / chevrotain 13 so bundles no longer include `lodash-es@4.17.23` - [#8285](mermaid-js/mermaid#8285) [`859f1f8`](mermaid-js/mermaid@859f1f8) Thanks [@mir-ashiq](https://github.com/mir-ashiq)! - fix(sequence): allow actor-menu keywords as participant ids in messages A participant declared as `Link` (or `Links`, `Properties`, `Details`) could not be used as a message endpoint: the lexer matched the name as the `link` statement keyword and the parse failed. The `link`, `links`, `properties` and `details` keywords are now only recognized when an actor follows them on the same line, so participant ids that happen to spell these words work in messages, while the statements themselves keep parsing as before. - [#8282](mermaid-js/mermaid#8282) [`b6d952d`](mermaid-js/mermaid@b6d952d) Thanks [@belomaxorka](https://github.com/belomaxorka)! - fix(sequence): allow `Link` as a participant ID in messages and actor menus Preserve the ID's case and alias while keeping the `link` and `links` menu commands supported. - [#8345](mermaid-js/mermaid#8345) [`7917c1a`](mermaid-js/mermaid@7917c1a) Thanks [@knsv-bot](https://github.com/knsv-bot)! - fix: xychart measures text in SVG units so legends no longer clip on wide charts scaled to fit their container, and the chart title is dropped instead of overflowing when the chart is too short for it - [#8338](mermaid-js/mermaid#8338) [`4a722fb`](mermaid-js/mermaid@4a722fb) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: Centre the xychart title over the plot area instead of the whole chart - Updated dependencies \[[`8afd83c`](mermaid-js/mermaid@8afd83c)]: - @mermaid-js/parser@2.0.1 Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: give me a 98K <240642031+inhuman-0@users.noreply.github.com>

Upstream release: https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4012.1.0 Release notes: ### Minor Changes - [#8303](mermaid-js/mermaid#8303) [`9140716`](mermaid-js/mermaid@9140716) Thanks [@filipsajdak](https://github.com/filipsajdak)! - feat: add the `elk.orientFeedbackEdges` option, enabled by default. With the ELK layout, an edge from a node that a subgraph feeds back into that subgraph is now routed downstream instead of around the subgraph. This changes the layout of existing ELK diagrams that contain such edges; set `elk.orientFeedbackEdges: false` to keep the previous routing. - [#8250](mermaid-js/mermaid#8250) [`fd4f5f2`](mermaid-js/mermaid@fd4f5f2) Thanks [@kartben](https://github.com/kartben)! - feat: add a `bitOrder` option to packet diagrams. It defaults to `ascending`, which is the current behaviour, and `descending` mirrors every row so it reads from that row's highest bit down to its lowest. Fields are still declared lowest bit first and keep their width, so switching a diagram between the two conventions only means changing `bitOrder`. ### Patch Changes - [#8330](mermaid-js/mermaid#8330) [`50c9e55`](mermaid-js/mermaid@50c9e55) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: upgrade chevrotain to 13 so mermaid no longer pulls in vulnerable `lodash-es@4.17.23` - [#8259](mermaid-js/mermaid#8259) [`4c90f5c`](mermaid-js/mermaid@4c90f5c) Thanks [@afonsojanu](https://github.com/afonsojanu)! - fix(sequence): allow whitespace between an actor name and its `@{ ... }` config object `participant Bob@{ "type" : "database" }` parsed fine, but adding a single space before the config object (`participant Bob @{ "type" : "database" }`) failed with a confusing parse error, even though the plain form without a config object tolerates trailing whitespace just fine. - [#8339](mermaid-js/mermaid#8339) [`c7fa1a5`](mermaid-js/mermaid@c7fa1a5) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: keep ELK class-diagram cardinalities off namespace frames - [#8334](mermaid-js/mermaid#8334) [`d67331d`](mermaid-js/mermaid@d67331d) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix(class): place cardinality labels beside their relation ends on dagre's sides with ELK, centre dagre's end labels, and stop clipping their text - [#8344](mermaid-js/mermaid#8344) [`99a050b`](mermaid-js/mermaid@99a050b) Thanks [@pbrolin47](https://github.com/pbrolin47)! - fix: with the ELK layout, an edge label could sit up to 16px beside its edge instead of centred on it, when the edge's terminal jog was straightened after the label's position was computed.

📑 Summary
Overriding one key of an object-valued theme variable no longer throws away the keys the theme generated for the rest of it.
Resolves #8299
On
develop, this turns a dark chart white:Every theme's
calculate()applies the user's overrides a second time, afterupdateColors(), withthis[k] = overrides[k]. ForxyChartthat replaces the 13-key object the theme just generated with the one key above. xychart then fills the gaps fromtheme-default, so the background comes outwhiteinstead of#333, and the axis text#131300instead of#e0dfdf.radar,wardley,cynefinandpackethave the same problem: the new spec fails for 28 theme/variable pairs ondevelop.📏 Design Decisions
applyOverride(generated, override)intheme-helpers.jsreturns{ ...generated, ...override }when both values are plain objects, andoverridefor anything else. So scalars, strings and arrays behave exactly as before. The first pass is unchanged. It already hands the user's keys toupdateColors(), which reads them throughthis.xyChart?.titleColor || ....calculate(). Each one now calls the shared helper instead of carrying its own merge. The diff in each theme is one line plus the import.theme-defaultfallbacks in the diagrams stay. With this fix they no longer fill anything for a built-in theme, but they still cover custom setups. Removing them is a separate change.xyChart.mdalready shows one-key overrides like the one above as the intended way to use these variables.Visual change. Three e2e fixtures override a nested theme variable. I rendered each one before and after the fix and compared the SVGs, with two renders of the fixed build as a control; the two renders were byte-identical:
xychart/render-all-the-theme-colorradar/should-handle-radar-diagram-with-radar-style-overridecynefin/should-render-cynefin-with-theme-overridetextColorandlabelColornow come from thebasetheme the fixture asks for, not fromtheme-default.
