add-svg-icon

name	add-svg-icon
description	Convert an SVG file (local path or URL) to a Compose ImageVector in the aktual-core:icons module. Defaults to AktualIcons; use --material for MaterialIcons.
argument-hint	<filepath-or-url> <IconName> [--material] [--size <N>]

Convert an SVG file to a Kotlin ImageVector and add it to the aktual-core/icons module.

Arguments

• $ARGUMENTS should contain:
  • A file path or URL to an SVG file
  • The icon name in PascalCase (e.g., MyIcon, BankTransfer)
  • --material (optional) — generate as a MaterialIcons extension instead of AktualIcons
  • --size <N> (optional) — override the icon size (default: derived from SVG viewBox)

Step-by-Step Process

1. Fetch the SVG

• If the argument is a URL: use WebFetch to download the SVG content
• If the argument is a file path: use Read to read the SVG file

2. Parse the SVG

Extract from the SVG:

• The viewBox attribute (e.g., "0 0 24 24" or "0 0 20 20")
  • Parse as minX minY width height
• The d attribute from each <path> element
• Any fill-rule="evenodd" on path elements

Determine the icon size:

• If --size was provided, use that value
• Otherwise, use the width from the viewBox (e.g., 24 from "0 0 24 24")

3. Convert path data to Kotlin

Convert SVG path commands to Kotlin PathBuilder calls:

SVG Command	Kotlin Call
M x,y	moveTo(xf, yf)
m dx,dy	moveToRelative(dxf, dyf)
L x,y	lineTo(xf, yf)
l dx,dy	lineToRelative(dxf, dyf)
H x	horizontalLineTo(xf)
h dx	horizontalLineToRelative(dxf)
V y	verticalLineTo(yf)
v dy	verticalLineToRelative(dyf)
C x1,y1 x2,y2 x,y	curveTo(x1f, y1f, x2f, y2f, xf, yf)
c dx1,dy1 dx2,dy2 dx,dy	curveToRelative(dx1f, dy1f, dx2f, dy2f, dxf, dyf)
S x2,y2 x,y	reflectiveCurveTo(x2f, y2f, xf, yf)
s dx2,dy2 dx,dy	reflectiveCurveToRelative(dx2f, dy2f, dxf, dyf)
Q x1,y1 x,y	quadTo(x1f, y1f, xf, yf)
q dx1,dy1 dx,dy	quadToRelative(dx1f, dy1f, dxf, dyf)
T x,y	reflectiveQuadTo(xf, yf)
t dx,dy	reflectiveQuadToRelative(dxf, dyf)
A rx,ry,rot,largeArc,sweep,x,y	arcTo(rxf, ryf, rotf, largeArc(bool), sweep(bool), xf, yf)
a rx,ry,rot,largeArc,sweep,dx,dy	arcToRelative(rxf, ryf, rotf, largeArc(bool), sweep(bool), dxf, dyf)
Z or z	close()

Number formatting:

• All coordinate values must end with f (Kotlin float literal)
• Use the exact numeric values from the SVG (don't round)
• Comma-separated values in SVG should become separate float arguments

4. Create the Kotlin file

Default: AktualIcons

Create the file at:

aktual-core/icons/src/commonMain/kotlin/aktual/core/icons/{IconName}.kt

Template:

@file:Suppress("BooleanLiteralArgument", "UnusedReceiverParameter")

package aktual.core.icons

import aktual.core.icons.internal.aktualIcon
import aktual.core.icons.internal.aktualPath
import androidx.compose.ui.graphics.vector.ImageVector

val AktualIcons.{IconName}: ImageVector by lazy {
  aktualIcon(name = "{IconName}", size = {size}f) {
    aktualPath {
      // converted path commands here
    }
  }
}

With --material flag: MaterialIcons

Create the file at:

aktual-core/icons/src/commonMain/kotlin/aktual/core/icons/material/{IconName}.kt

Template:

@file:Suppress("UnusedReceiverParameter")

package aktual.core.icons.material

import aktual.core.icons.material.internal.materialIcon
import aktual.core.icons.material.internal.materialPath
import androidx.compose.ui.graphics.vector.ImageVector

val MaterialIcons.{IconName}: ImageVector by lazy {
  materialIcon(name = "{IconName}") {
    materialPath {
      // converted path commands here
    }
  }
}

For MaterialIcons, the default viewport is 24f. If the SVG viewBox is not 24x24, pass viewportSize = {size}f to materialIcon().

Multiple paths: If the SVG has multiple <path> elements, use multiple aktualPath { } or materialPath { } blocks.

Even-odd fill rule: If any path has fill-rule="evenodd", pass pathFillType = PathFillType.EvenOdd to aktualPath or materialPath and add the import import androidx.compose.ui.graphics.PathFillType.

5. Update preview file

AktualIcons (default): Read aktual-core/icons/src/commonMain/kotlin/aktual/core/icons/IconPreviews.kt. Add the new icon name to the aktualIcons list in alphabetical order.

MaterialIcons (--material): Read aktual-core/icons/src/commonMain/kotlin/aktual/core/icons/material/MaterialIconPreviews.kt. Add the new icon name to the materialIcons list in alphabetical order.

6. Verify

Run ./gradlew :aktual-core:icons:compileAll to verify the icon compiles correctly.

Important Notes

• Check that a file with this icon name doesn't already exist before creating it
• The icon name in the file must match the PascalCase name used as the extension property name
• Always use by lazy for the property delegate
• Always include the @file:Suppress annotation at the top
• For AktualIcons, include both "BooleanLiteralArgument" and "UnusedReceiverParameter" suppressions
• For MaterialIcons, only "UnusedReceiverParameter" is needed
• AktualIcons use aktualIcon + aktualPath from aktual.core.icons.internal
• MaterialIcons use materialIcon + materialPath from aktual.core.icons.material.internal
