From 5e1e1befd60716e8e20024a0fceaf7cf37975e45 Mon Sep 17 00:00:00 2001 From: Claw Explorer Date: Sat, 4 Apr 2026 15:21:19 -0400 Subject: [PATCH] fix: correct parseInt radix parameters and use parseFloat for dimensions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three footprint generators used the wrong radix in Number.parseInt(), causing string-based pin count parsing to silently return NaN: - sot323.ts: parseInt(match[1]!, 3) → parseInt(match[1]!, 10) Radix 3 only accepts digits 0-2, so '3' returns NaN - sot23w.ts: parseInt(match[1]!, 3) → parseInt(match[1]!, 10) Same base-3 issue - sot343.ts: parseInt(match[1]!, 4) → parseInt(match[1]!, 10) Radix 4 only accepts digits 0-3, so '4' returns NaN The second argument to parseInt() was accidentally set to the default pin count instead of the radix (10). This meant parsing any pin count from the string always failed, falling back to defaults. Also fixes parseInt → parseFloat for silkscreen ref text positioning in sot23, sot23w, and sot323, where parseInt('2.50mm') truncated to 2 instead of using the correct 2.5mm value. Adds explicit radix 10 to parseInt calls in to220, to220f, and bga for consistency and to follow best practices. All 389 tests pass (4 new regression tests added). --- src/fn/bga.ts | 2 +- src/fn/sot23.ts | 2 +- src/fn/sot23w.ts | 4 +- src/fn/sot323.ts | 4 +- src/fn/sot343.ts | 2 +- src/fn/to220.ts | 2 +- src/fn/to220f.ts | 1 + tests/__snapshots__/sot23.snap.svg | 2 +- tests/__snapshots__/sot23_3.snap.svg | 2 +- .../sot23_w3_h1.5_p0.95mm.snap.svg | 2 +- tests/__snapshots__/sot23w.snap.svg | 2 +- .../sot23w_p2_w5.1_h5.2.snap.svg | 2 +- tests/__snapshots__/sot25.snap.svg | 1 + tests/__snapshots__/sot323.snap.svg | 2 +- .../kicad-parity/__snapshots__/sot23.snap.svg | 2 +- .../__snapshots__/sot323.snap.svg | 2 +- tests/parseint-radix.test.ts | 41 +++++++++++++++++++ 17 files changed, 59 insertions(+), 16 deletions(-) create mode 100644 tests/__snapshots__/sot25.snap.svg create mode 100644 tests/parseint-radix.test.ts diff --git a/src/fn/bga.ts b/src/fn/bga.ts index 8a712184..f354e890 100644 --- a/src/fn/bga.ts +++ b/src/fn/bga.ts @@ -55,7 +55,7 @@ export const bga_def = base_def const m = s.match(/([A-Z]+)(\d+)/) if (!m) return s const Y = ALPHABET.indexOf(m[1]!) - const X = Number.parseInt(m[2]!) - 1 + const X = Number.parseInt(m[2]!, 10) - 1 return Y * a.grid!.x + X + 1 }) } diff --git a/src/fn/sot23.ts b/src/fn/sot23.ts index d8852d98..9cdf1c21 100644 --- a/src/fn/sot23.ts +++ b/src/fn/sot23.ts @@ -106,7 +106,7 @@ export const sot23_3 = (parameters: z.infer) => { } const silkscreenRefText: SilkscreenRef = silkscreenRef( 0, - Number.parseInt(parameters.h), + Number.parseFloat(parameters.h), 0.3, ) diff --git a/src/fn/sot23w.ts b/src/fn/sot23w.ts index 042aad3b..595d3c50 100644 --- a/src/fn/sot23w.ts +++ b/src/fn/sot23w.ts @@ -23,7 +23,7 @@ export const sot23w = ( raw_params: z.input, ): { circuitJson: AnyCircuitElement[]; parameters: any } => { const match = raw_params.string?.match(/^sot23w_(\d+)/) - const numPins = match ?
