import FilePaths harmful for load time

[jaakkor2]

• what version of Makie are you running? (]st -m Makie)

Status `C:\Users\jaakkor2\MyTemp\debug\Project.toml`
  [8bb1440f] DelimitedFiles v1.9.1
  [cd3eb016] HTTP v1.10.15
  [ee78f7c6] Makie v0.22.2 `C:\Users\jaakkor2\.julia\dev\Makie`
  [477bde09] MyDebugPkg v1.0.0-DEV `C:\Users\jaakkor2\.julia\dev\MyDebugPkg`
  [bca83a33] OptimizationBase v2.4.0

• can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie)
• What platform + GPU are you on? WIndows 11, Intel i7-1370P with integrated GPU

On Julia v"1.12.0-DEV.2047" (1.12-nightly in juliaup), a package with only these lines shows considerably longer using times due to import of FilePaths in Makie.

module MyDebugPkg

import HTTP
import DelimitedFiles
import OptimizationBase
using Makie

import FilePaths

improves usage time considerably, @time using MyDebugPkg outputs

master

  6.175683 seconds (9.32 M allocations: 499.577 MiB, 5.25% gc time, 23.91% compilation time: 79% of which was recompilation)

without FilePaths

  4.779248 seconds (7.07 M allocations: 381.341 MiB, 6.74% gc time, 1.56% compilation time: 65% of which was recompilation)

Makie is the only user of FilePaths

(debug) pkg> why FilePaths
  Makie → FilePaths
  MyDebugPkg → Makie → FilePaths

Related report on Electron was filed, but closed davidanthoff/Electron.jl#128.

Huh yeah this is not good. Of course we only have it due to Electron having it, but I don't think we should penalize CairoMakie and GLMakie users that much for something which only affects WGLMakie...

[SimonDanisch]

Oh wow, didn't realize the impact was that big....
Maybe someone can invest some time into fixing Electron... I'm quite sure that it's not absolutely necessary, or could just extract a few of the functions from FilePaths.

With FilePaths v0.9 I do not observe penalty from import FilePaths. This is with Julai Version 1.12.0-DEV.2047 (2025-02-26).
