  1. 1 毫秒重排你正在编辑的段落 rtex 让加载好 preamble 的 LuaLaTeX 只重排光标所在段落,约 1 毫秒把新行交给编辑器,整篇编译在后台处理分页和引用。 HenryXiaoYang/realtime-tex t.co

  2. 一直眼馋 Typst 那种即时预览,可论文还是得写 LaTeX。 TUG 2026 有篇论文讲的就是 LaTeX 实时排版,可惜里面的 texlode 没开源,于是有人照着思路自己做了一个:realtime-tex。 GitHub:HenryXiaoYang/realtime-tex VS Code 插件:HenryXiaoYang/realtime-tex-vsc-plugin 用原论文开源的 bench 跑,300 页的文档每次编辑刷新 1.3 ms,typst watch 是 414 ms,完整跑一遍 pdfLaTeX 要 0.51 s。 这下真是拳打 Overleaf 脚踢 Typst 了。

    I made a live LaTeX preview that updates as you type (~1 ms per keystroke, output identical to LuaLaTeX) I've always envied Typst's instant preview, but my papers have to stay in LaTeX. So I built rtex, which keeps a LuaLaTeX process warm with your preamble loaded and re-typesets only the paragraph you're editing. It takes about a millisecond, and document length doesn't matter: a 300-page book is as fast as a 10-page one. It's a VS Code extension for now: HenryXiaoYang/realtime-tex-vsc-plugin Limits: LuaLaTeX only, and things like TikZ and preamble edits wait for the background compile. Based on Clemens Lode's TUGboat paper "Real-Time LuaTeX". Code: HenryXiaoYang/realtime-tex Note: Vibe-coded software
