-### Mapping CI CD jobs to local commands
-
-When you see the CI CD fail on jobs you may wonder three things
-
-- Do I have a bug in my code?
-- Is the test flaky?
-- Is there a bug in `main`?
-
-To answer these questions the following commands will give you confidence to locate the issue.
-
-#### Static Analysis
-
-Part of the CI CD pipeline performs static analysis on the code. Use the following commands to mimic the CI CD jobs.
-
-The following set of commands should get us closer to one and done commands to instantly retest issues.
-
-```
-npm run test-setup
-```
-
-> Gotcha, are packages up to date and is the wasm built?
-
-```
-npm run tsc
-npm run fmt:check
-npm run lint
-npm run test:unit:local
-```
-
-> Gotcha: Our unit tests have integration tests in them. You need to run a localhost server to run the unit tests.
-
-#### E2E Tests
-
-**Playwright Electron**
-
-These E2E tests run in electron. There are tests that are skipped if they are ran in a windows, linux, or macos environment. We can use playwright tags to implement test skipping.
-
-```
-npm run test:playwright:electron:local
-npm run test:playwright:electron:windows:local
-npm run test:playwright:electron:macos:local
-npm run test:playwright:electron:ubuntu:local
-```
-
-> Why does it say local? The CI CD commands that run in the pipeline cannot be ran locally. A single command will not properly setup the testing environment locally.
-
-#### Some notes on CI
-
-The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion `git reset --hard HEAD~ && git push -f` is your friend.
-
-How to interpret failing playwright tests?
-If your tests fail, click through to the action and see that the tests failed on a line that includes `await page.getByTestId('loading').waitFor({ state: 'detached' })`, this means the test fail because the stream never started. It's you choice if you want to re-run the test, or ignore the failure.
-
-We run on ubuntu and macos, because safari doesn't work on linux because of the dreaded "no RTCPeerConnection variable" error. But linux runs first and then macos for the same reason that we limit the number of parallel tests to 1 because we limit stream connections per user, so tests would start failing we if let them run together.
-
-If something fails on CI you can download the artifact, unzip it and then open `playwright-report/data/<UUID>.zip` with https://trace.playwright.dev/ to see what happened.
-
-#### Getting started writing a playwright test in our app
-
-Besides following the instructions above and using the playwright docs, our app is weird because of the whole stream thing, which means our testing is weird. Because we've just figured out this stuff and therefore docs might go stale quick here's a 15min vid/tutorial

+KCL supports the usual arithmetic operators on numbers and logic operators on booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `+` | Addition |
+| `-` | Subtraction or unary negation |
+| `*` | Multiplication |
+| `/` | Division |
+| `%` | Modulus aka remainder |
+| `^` | Power, e.g., `x ^ 2` means `x` squared |
+| `&` | Logical 'and' |
+| `|` | Logical 'or' |
+| `!` | Unary logical 'not' |
+
+KCL also supports comparsion operators which operate on numbers and produce booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `==` | Equal |
+| `!=` | Not equal |
+| `<` | Less than |
+| `>` | Greater than |
+| `<=` | Less than or equal |
+| `>=` | Greater than or equal |
+
+Arithmetics and logic expressions can be arbitrairly combined with the usual rules of associativity and precedence, e.g.,
+
+```
+myMathExpression = 3 + 1 * 2 / 3 - 7
+```
+
+You can also nest expressions in parenthesis:
+
+```
+myMathExpression = 3 + (1 * 2 / (3 - 7))
+```
+
+KCL numbers are implemented using [floating point numbers](https://en.wikipedia.org/wiki/Floating-point_arithmetic). This means that there are occasionally representation and rounding issues, and some oddities such as supporting positive and negative zero.
+
+Some operators can be applied to other types:
+
+- `+` can be used to concatenate strings, e.g., `'hello' + ' ' + 'world!'`
+- Unary `-` can be used with planes or line-like objects such as axes to produce an object with opposite orientation, e.g., `-XY` is a plain which is aligned with `XY` but whose normal aligns with the negative Z axis.
+- The following operators can be used with solids as shorthand for CSG operations:
+  - `+` or `|` for [`union`](/docs/kcl-std/union).
+  - `-` for [`subtract`](/docs/kcl-std/subtract).
+  - `&` for [`intersect`](/docs/kcl-std/intersect)

+
+Arrays are sequences of values.
+
+Arrays can be written out as *array literals* using a sequence of expressions surrounded by square brackets, e.g., `['hello', 'world']` is an array of strings, `[x, x + 1, x + 2]` is an array of numbers (assuming `x` is a number), `[]` is an empty array, and `['hello', 42, true]` is a mixed array.
+
+A value in an array can be accessed by indexing using square brackets where the index is a number, for example, `arr[0]`, `arr[42]`, `arr[i]` (where `arr` is an array and `i` is a (whole) number).
+
+There are some useful functions for working with arrays in the standard library, see [std::array](/docs/kcl-std/modules/std-array) for details.
+
+## Array types
+
+Arrays have their own types: `[T]` where `T` is the type of the elements of the array, for example, `[string]` means an array of `string`s and `[any]` means an array of any values.
+
+Array types can also include length information: `[T; n]` denotes an array of length `n` (where `n` is a number literal) and `[T; 1+]` denotes an array whose length is at least one (i.e., a non-empty array). E.g., `[string; 1+]` and `[number(mm); 3]` are valid array types.
+
+## Ranges
+
+Ranges are a succinct way to create an array of sequential numbers. The syntax is `[start .. end]` where `start` and `end` evaluate to whole numbers (integers). Ranges are inclusive of the start and end. The end must be greater than the start. Examples:
+
+```kcl,norun
+[0..3]      // [0, 1, 2, 3]
+[3..10]     // [3, 4, 5, 6, 7, 8, 9, 10]
+x = 2
+[x..x+1]    // [2, 3]
+```
+
+The units of the start and end numbers must be the same and the result inherits those units.

+
+Attributes are syntax which affects the language item they annotate. In KCL they are indicated using `@`. For example, `@settings` affects the file in which it appears.
+
+There are two kinds of attributes: named and unnamed attributes. Named attributes (e.g., `@settings`) have a name immediately after the `@` (e.g., `settings`) and affect their surrounding scope. Unnamed attributes have no name and affect the following item, e.g.,
+
+```kcl,norun
+@(lengthUnit = ft, coords = opengl)
+import "tests/inputs/cube.obj"
+```
+
+has an unnamed attribute on the `import` statement.
+
+Named and unnamed attributes may take a parenthesized list of arguments (like a function). Named attributes may also appear without any arguments (e.g., `@no_std`).
+
+## Named attributes
+
+The `@settings` attribute affects the current file and accepts the following arguments: `defaultLengthUnit`, `defaultAngleUnit`, and `kclVersion`. See [settings](/docs/kcl-lang/settings) for details.
+
+The `@no_std` attribute affects the current file, takes no arguments, and causes the standard library to not be implicitly available. It can still be used by being explicitly imported.
+
+## Unnamed attributes
+
+Unnamed attributes may be used on `import` statements when importing non-KCL files. See [projects, modules, and imports](/docs/kcl-lang/modules) for details.
+
+Other unnamed attributes are used on functions inside the standard library, but these are not available in user code.

+## Performance deep‑dive for foreign‑file imports

+—and structure your code to defer blocking operations until the end.
+
+### Foreign import execution stages
+
+1. **Import (Read / Initialization) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+   ```
+   - Reads the file from disk and makes its API available.
+   - Starts engine rendering but **does not block** your script.
+   - This kick‑starts the render pipeline while you keep executing other code.
+
+2. **Invocation (Blocking) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+
+   cube
+     |> translate(z=10) // ← blocks here only
+   ```
+   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
+
+### Best practices
+
+#### 1. Defer blocking calls
+
+```kcl
+import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
+
+
+// --- perform other operations and calculations here ---
+
+
+cube
+  |> translate(z=10)                        // 2) Blocks only here
+```
+
+#### 2. Split heavy work into separate modules
+
+Place computationally expensive or IO‑heavy work into its own module so it can render in parallel while `main.kcl` continues.
+
+#### Future improvements
+
+Upcoming releases will auto‑analyse dependencies and only block when truly necessary. Until then, explicit deferral will give you the best performance.

+excerpt: "Documentation of the KCL language for the Zoo Design Studio."
+layout: manual
+---
+
+Numbers and numeric types in KCL include information about the units of the numbers. So rather than just having a number like `42`, we always have information about the units so we don't confuse 42 mm with 42 inches.
+
+
+## Numeric literals
+
+When writing a number literal, you can use a unit suffix to explicitly state the unit, e.g., `42mm`. The following units are available:
+
+- Length units:
+  - metric: `mm`, `cm`, `m`
+  - imperial: `in`, `ft`, `yd`
+- Angle units: `deg`, `rad`
+- `_` to indicate a unitless number such as a count or ratio.
+
+If you write a numeric literal without a suffix, then the defaults for the current file are used. These defaults are specified using the `@settings` attribute, see [settings](/docs/kcl-lang/settings) for details. Note that if using the defaults, the KCL interpreter won't know whether you intend the number to be a length, angle, or count and will treat it as being possibly any of them.
+
+
+## Numeric types
+
+Just like numbers carry units information, the `number` type also includes units information. Units are written in parentheses after the type, e.g., `number(mm)`.
+
+Any of the suffixes described above can be used meaning that values with that type have the supplied units. E.g., `number(mm)` is the type of number values with mm units and `number(_)` is the type of number values with no units.
+
+You can also use `number(Length)`, `number(Angle)`, or `number(Count)`. These types mean a number with any length, angle, or unitless (count) units, respectively (note that `number(_)` and `number(Count)` are equivalent since there is only one kind of unitless-ness).
+
+Using just `number` means accepting any kind of number, even where the units are unknown by KCL.
+
+
+## Function calls
+
+When calling a function with an argument with numeric type, the declared numeric type in the function signature and the units of the argument value used in the function call must be compatible. Units are adjusted automatically. For example, if a function requires an argument with type `number(mm)`, then you can call it with `2in` and the units will be automatically adjusted, but calling it with `90deg` will cause an error.
+
+
+## Mixing units with arithmetic
+
+When doing arithmetic or comparisons, units will be adjusted as necessary if possible. However, often arithmetic expressions exceed the ability of KCL to accurately choose units which can result in warnings in your code or sometimes errors. In these cases, you will need to give KCL more information. Sometimes this can be done by making units explicit using suffixes. If not, then you will need to use *type ascription*, which asserts that an expression has the supplied type. For example, `(x * y): number(mm)` tells KCL that the units of `x * y` is mm. Note that type ascription does not do any adjustment of the numbers, e.g., `2mm: number(in)` has the value `2in` (note that this would be a very non-idiomatic way to use numeric type ascription, you could simply write `2in`. Usually type ascription is only necessary for supplying type information about the result of computation).
+
+KCL has no support for area, volume, or other higher dimension units. When internal unit tracking requires multiple dimensions, KCL essentially gives up. This is usually where the extra type information described above is needed. If doing computation with higher dimensioned units, you must ensure that all adjustments occur before any computation. E.g., if you want to compute an area with unknown units, you must convert all numbers to the same unit before starting.
+
+
+## Explicit conversions
+
+You might sometimes need to convert from one unit to another for some calculation. You can do this implicitly when calling a function (see above), but if you can't or don't want to, then you can use the explicit conversion functions in the [`std::units`](/docs/kcl-std/modules/std-units) module.

-- **Sketch on Face**: If your sketch is outside the edges of the face (on which you
-    are sketching) you will get multiple models returned instead of one single
-    model for that sketch and its underlying 3D object.
-    If you see a red line around your model, it means this is happening.

-
-`KCL` allows splitting code up into multiple files.  Each file is somewhat
-isolated from other files as a separate module.
-
-When you define a function, you can use `export` before it to make it available
-to other modules.
-
-```kcl
-// util.kcl
-export fn increment(@x) {
-  return x + 1
-}
-```
-
-Other files in the project can now import functions that have been exported.
-This makes them available to use in another file.
-
-```norun
-// main.kcl
-import increment from "util.kcl"
-
-answer = increment(41)
-```
-
-Imported files _must_ be in the same project so that units are uniform across
-modules. This means that it must be in the same directory.
-
-Import statements must be at the top-level of a file. It is not allowed to have
-an `import` statement inside a function or in the body of an if‑else.
-
-Multiple functions can be exported in a file.
-
-```kcl
-// util.kcl
-export fn increment(@x) {
-  return x + 1
-}
-
-export fn decrement(@x) {
-  return x - 1
-}
-```
-
-When importing, you can import multiple functions at once.
-
-```norun
-import increment, decrement from "util.kcl"
-```
-
-Imported symbols can be renamed for convenience or to avoid name collisions.
-
-```norun
-import increment as inc, decrement as dec from "util.kcl"

-## Functions vs `clone`
-
-There are two common patterns for re‑using geometry:
-
-1. **Wrap the construction in a function** – flexible and fully parametric.
-2. **Duplicate an existing object with `clone`** – lightning‑fast, but an exact
-   duplicate.
-
-### Parametric function example
-
-```kcl
-fn cube(center) {
-  return startSketchOn(XY)
-    |> startProfile(at = [center[0] - 10, center[1] - 10])
-    |> line(endAbsolute = [center[0] + 10, center[1] - 10])
-    |> line(endAbsolute = [center[0] + 10, center[1] + 10])
-    |> line(endAbsolute = [center[0] - 10, center[1] + 10])
-    |> close()
-    |> extrude(length = 10)
-}
-
-myCube = cube(center = [0, 0])
-```
-
-*Pros*
-- Any argument can be a parameter – size, position, appearance, etc.
-- Works great inside loops, arrays, or optimisation sweeps.
-
-*Cons*
-- Every invocation rebuilds the entire feature tree.
-- **Slower** than a straight duplicate – each call is its own render job.
-
-### `clone` example
-
-```kcl
-sketch001 = startSketchOn(-XZ)
-  |> circle(center = [0, 0], radius = 10)
-  |> extrude(length = 5) 
-  |> appearance(color = "#ff0000", metalness = 90, roughness = 90)
-
-sketch002 = clone(sketch001)  // ✓ instant copy
-```
-
-*Pros*
-- Roughly an O(1) operation – we just duplicate the underlying engine handle.
-- Perfect when you need ten identical bolts or two copies of the same imported STEP file.
-
-*Cons*
-- **Not parametric** – the clone is exactly the same shape as the source.
-- If you need to tweak dimensions per‑instance, you’re back to a function.
-
-> **Rule of thumb** – Reach for `clone` when the geometry is already what you want. Reach for a function when you need customisation.
-
----
-
-## Module‑level parallelism
-
-Under the hood, the Design Studio runs **every module in parallel** where it can. This means:
-
-- The top‑level code of `foo.kcl`, `bar.kcl`, and `baz.kcl` all start executing immediately and concurrently.
-- Imports that read foreign files (STEP/OBJ/…) overlap their I/O and background render.
-- CPU‑bound calculations in separate modules get their own worker threads.
-
-### Why modules beat one‑big‑file
-
-If you shoe‑horn everything into `main.kcl`, each statement runs sequentially:
-
-```norun
-import "big.step" as gizmo  // blocks main while reading
-
-gizmo |> translate(x=50)    // blocks again while waiting for render
-```
-
-Split `gizmo` into its own file and the read/render can overlap whatever else `main.kcl` is doing.
-
-```norun
-// gizmo.kcl                   (worker A)
-import "big.step"
-
-// main.kcl                    (worker B)
-import "gizmo.kcl" as gizmo   // non‑blocking
-
-// ... other setup ...
-
-gizmo |> translate(x=50)      // only blocks here
-```
-
-### Gotcha: defining but **not** calling functions
-
-Defining a function inside a module is instantaneous – we just record the byte‑code. The heavy lifting happens when the function is **called**. So:
-
-```norun
-// util.kcl
-export fn makeBolt(size) { /* … expensive CAD … */ }
-```
-
-If `main.kcl` waits until the very end to call `makeBolt`, *none* of that work was parallelised – you’ve pushed the cost back onto the serial tail of your script.
-
-**Better:** call it early or move the invocation into another module.
-
-```norun
-// bolt_instance.kcl
-import makeBolt from "util.kcl"
-bolt = makeBolt(5)  // executed in parallel
-bolt
-```
-
-Now `main.kcl` can `import "bolt_instance.kcl" as bolt` and get the result that was rendered while it was busy doing other things.
-
----
-
-## Whole module import
-
-You can also import the whole module. This is useful if you want to use the
-result of a module as a variable, like a part.
-
-```norun
-import "tests/inputs/cube.kcl" as cube
-cube
-  |> translate(x=10)
-```
-
-This imports the whole module and makes it available as `cube`. You can then
-use it like any other object. The `cube` variable is now a reference to the
-result of the module. This means that if you change the module, the `cube`
-variable will change as well.
-
-In `cube.kcl`, you cannot have multiple objects. It has to be a single part. If
-you have multiple objects, you will get an error. This is because the module is
-expected to return a single object that can be used as a variable.
-
-The last expression or variable definition becomes the module's return value.
-The module is expected to return a single object that can be used as a variable
-by whatever imports it.
-
-So for example, this is allowed:
-
-```norun
-... a bunch of code to create cube and cube2 ...
-
-myUnion = union([cube, cube2])
-```
-
-You can also do this:
-
-```norun
-... a bunch of code to create cube and cube2 ...
-
-union([cube, cube2])
-```
-
-Either way, the last line will return the union of the two objects.
-
-Or what you could do instead is:
-
-```norun
-... a bunch of code to create cube and cube2 ...
-
-myUnion = union([cube, cube2])
-myUnion
-```
-
-This will assign the union of the two objects to a variable, and then return it
-on the last statement. It's simply another way of doing the same thing.
-
-The final statement is what's important because it's the return value of the
-entire module. The module is expected to return a single object that can be used
-as a variable by the file that imports it.
-
----
-
-## Multiple instances of the same import
-
-Whether you are importing a file from another CAD system or a KCL file, that
-file represents object(s) in memory. If you import the same file multiple times,
-it will only be rendered once.
-
-If you want to have multiple instances of the same object, you can use the
-[`clone`](/docs/kcl/clone) function. This will render a new instance of the object in memory.
-
-```norun
-import cube from "tests/inputs/cube.kcl"
-
-cube  
-  |> translate(x=10)
-clone(cube)
-  |> translate(x=20)
-```
-
-In the sample above, the `cube` object is imported from a KCL file. The first
-instance is translated 10 units in the x direction. The second instance is
-cloned and translated 20 units in the x direction. The two instances are now
-separate objects in memory, and can be manipulated independently.
-
-Here is an example with a file from another CAD system:
-
-```kcl
-import "tests/inputs/cube.step" as cube
-
-cube
-  |> translate(x=10)
-clone(cube)
-  |> translate(x=20)
-```
-
----
-
-## Importing files from other CAD systems
-
-`import` can also be used to import files from other CAD systems. The format of the statement is the
-same as for KCL files. You can only import the whole file, not items from it. E.g.,
-
-```norun
-import "tests/inputs/cube.obj"
-
-// Use `cube` just like a KCL object.
-```
-
-```kcl
-import "tests/inputs/cube.sldprt" as cube
-
-// Use `cube` just like a KCL object.
-```
-
-For formats lacking unit data (such as STL, OBJ, or PLY files), the default
-unit of measurement is millimeters. Alternatively you may specify the unit
-by using an attribute. Likewise, you can also specify a coordinate system. E.g.,
-
-```kcl
-@(lengthUnit = ft, coords = opengl)
-import "tests/inputs/cube.obj"
-```
-
-When importing a GLTF file, the bin file will be imported as well.
-
-Import paths are relative to the current project directory. Imports currently only work when
-using the native Design Studio, not in the browser.
-
-### Supported values
-
-File formats: `fbx`, `gltf`/`glb`, `obj`+, `ply`+, `sldprt`, `step`/`stp`, `stl`+. (Those marked with a
-'+' support customising the length unit and coordinate system).
-
-Length units: `mm` (the default), `cm`, `m`, `inch`, `ft`, `yd`.
-
-Coordinate systems:
-
-- `zoo` (the default), forward: -Y, up: +Z, handedness: right
-- `opengl`, forward: +Z, up: +Y, handedness: right
-- `vulkan`, forward: +Z, up: -Y, handedness: left
-
----
-
-## Performance deep‑dive for foreign‑file imports
-
-Parallelized foreign‑file imports now let you overlap file reads, initialization,
-and rendering. To maximize throughput, you need to understand the three distinct
-stages—reading, initializing (background render start), and invocation (blocking)
-—and structure your code to defer blocking operations until the end.
-
-### Foreign import execution stages
-
-1. **Import (Read / Initialization) Stage**
-   ```kcl
-   import "tests/inputs/cube.step" as cube
-   ```
-   - Reads the file from disk and makes its API available.
-   - Starts engine rendering but **does not block** your script.
-   - This kick‑starts the render pipeline while you keep executing other code.
-
-2. **Invocation (Blocking) Stage**
-   ```kcl
-   import "tests/inputs/cube.step" as cube
-
-   cube
-     |> translate(z=10) // ← blocks here only
-   ```
-   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
-
-### Best practices
-
-#### 1. Defer blocking calls
-
-```kcl
-import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
-
-
-// --- perform other operations and calculations here ---
-
-
-cube
-  |> translate(z=10)                        // 2) Blocks only here
-```
-
-#### 2. Split heavy work into separate modules
-
-Place computationally expensive or IO‑heavy work into its own module so it can render in parallel while `main.kcl` continues.
-
-#### Future improvements
-
-Upcoming releases will auto‑analyse dependencies and only block when truly necessary. Until then, explicit deferral will give you the best performance.

-# KCL Settings
-
-There are three levels of settings available in Zoo Design Studio:
-
-1. [User Settings](/docs/kcl/settings-user): Global settings that apply to all projects, stored in `user.toml`
-2. [Project Settings](/docs/kcl/settings-project): Settings specific to a project, stored in `project.toml`
-3. Per-file Settings: Settings that apply to a single KCL file, specified using the `@settings` attribute
-
-## Configuration Files
-
-Zoo Design Studio uses TOML files for configuration:
-
-* **User Settings**: `user.toml` - See [complete documentation](/docs/kcl/settings-user)
-* **Project Settings**: `project.toml` - See [complete documentation](/docs/kcl/settings-project)
-
-## Per-file settings
-
-Settings which affect a single file are configured using the settings attribute.
-This must be at the top of the KCL file (comments before the attribute are permitted).
-For example:
-
-```kcl
-// The settings attribute.
-@settings(defaultLengthUnit = in)
-
-// The rest of your KCL code goes below...
-
-x = 42 // Represents 42 inches.
-```
-
-The settings attribute may contain multiple properties separated by commas.
-Valid properties are:
-
-- `defaultLengthUnit`: the default length unit to use for numbers declared in this file.
-  - Accepted values: `mm`, `cm`, `m`, `in` (inches), `ft` (feet), `yd` (yards).
-- `defaultAngleUnit`: the default angle unit to use for numbers declared in this file.
-  - Accepted values: `deg` (degrees), `rad` (radians).
-
-These settings override any project-wide settings (configured in project.toml or via the UI).
