Windows10でVScodeのlatex-workshopのexternal pdfをsmatraPDFにしてsynctexを使ったforward searchとinverse searchの設定をする．いくつか参照して試行錯誤したのでメモ．

VScode側の設定

settings.josonに以下を追加．

"latex-workshop.view.pdf.viewer": "external",
"latex-workshop.view.pdf.external.viewer.command": 
        "C:\\Users\\[username]\\AppData\\Local\\SumatraPDF\\SumatraPDF.exe",
"latex-workshop.view.pdf.external.viewer.args": [
        "-reuse-instance",
        "%PDF%"
],
"latex-workshop.view.pdf.external.synctex.command": 
        "C:\\Users\\[username]\\AppData\\Local\\SumatraPDF\\SumatraPDF.exe",
"latex-workshop.view.pdf.external.synctex.args": [
    "-forward-search",
    "%TEX%",
    "%LINE%",
    "-reuse-instance",
    "-inverse-search",
    "C:\\Users\\[username]\\AppData\\Local\\Programs\\Microsoft VS Code\\Code.exe \"C:\\Users\\[username]\\AppData\\Local\\Programs\\Microsoft VS Code\\resources\\app\\out\\cli.js\" -r -g \"%f:%l\"", //put same code on Smatra pdf option
    "%PDF%",
],

smatraPDF側の設定

詳細設定に以下を追加

InverseSearchCmdLine = C:\Users\[username]\AppData\Local\Programs\Microsoft VS Code\Code.exe "C:\Users\[username]\AppData\Local\Programs\Microsoft VS Code\resources\app\out\cli.js" -r -g "%f:%l"

#使い方
Ctrl+Alt+JでVScode上のソースからsmatraPDFに飛ぶ．
PDFダブルクリックでsmatraPDFからVScode上のソースに飛ぶ．
