#### Post date: [October 1, 2024, 8:29am UTC](https://discourse.nixosstag.fcio.net/t/jetbrains-vmoptfiles/53738/1 "2024-10-01T08:29:13Z")
我有一个相当复杂的问题。
我想使用ja-netfilter破解我的nixos电脑上的 idea ，这里是[例子](https://github.com/LostAttractor/flake/blob/eedb0b1888f69f4998f57747c1a066c2183db930/user/programs/jetbrains.nix)
问题是，当我尝试使用overrideAttrs来替换原始vmoptsFile Attrs来实现相同的操作时，
> ` xdg.configFile."JetBrains/PyCharm${pkgs.jetbrains.pycharm-professional.version}/pycharm64.vmoptions".text =vmoptions`.
似乎无法从安装之后的 idea 文件中被正常检出，换句话说就是就算我用 overrideAttrs 替换了 jetbrains 中原始的 vmoptFiles，他还是无法作为一个参数被 installPhase 中的变量提取拿到。
```nix
# nixpkgs ... all-packages.nix
vmopts = config.jetbrains.vmopts or null;
# nixpkgs ... jetbrains/bin/linux.nix
> vmoptsFile = lib.optionalString (vmopts != null) (writeText vmoptsName vmopts);
> wrapProgram "$launcher" \
--prefix PATH : "${lib.makeBinPath [jdk coreutils gnugrep which git]}" \
--suffix PATH : "${lib.makeBinPath [python3]}" \
--prefix LD_LIBRARY_PATH : "${lib.makeLibraryPath extraLdPath}" \
${lib.concatStringsSep " " extraWrapperArgs} \
--set-default JDK_HOME "$jdk" \
--set-default ANDROID_JAVA_HOME "$jdk" \
--set-default JAVA_HOME "$jdk" \
--set-default JETBRAINS_CLIENT_JDK "$jdk" \
--set-default ${hiName}_JDK "$jdk" \
--set-default LOCALE_ARCHIVE "${glibcLocales}/lib/locale/locale-archive" \
--set-default ${vmoptsIDE}_VM_OPTIONS ${vmoptsFile}
```
= 我修改的 modules ==================================================================
```nix
let
vmoptions = pkgs.writeText "jetbrains-with-ja-netfilter-vmoptions" ''
....
-javaagent:${jetbra}/ja-netfilter.jar=jetbrains
'';
generateOverridePackage =
pkgName: pkgName.overrideAttrs { vmoptsFile = vmoptions; }
;
in {
options = {
programs.jetbrains = {
enable = lib.options.mkEnableOption "jetbrains";
packages = lib.mkOption {
type = types.listOf types.package;
default = [];
description = "A list of packages need to enable ja-netfilter.";
example = [pkgs.jetbrains.idea-ultimate];
};
};
};
config = lib.mkIf (cfg.enable && cfg.packages != []) {
home.packages = map (pkg: generateOverridePackage pkg) cfg.packages;
};
```

but this time vmoptsFile existed with a name that i config.

but the file still not existed.
= FINAL STATEMENT ===========================================================================
1. 这俩 derivation 文件到底哪个是我 HM 里面用的？
2. 当我查看[nixpkgs source](https://github.com/NixOS/nixpkgs/blob/ead36718ebca64b22afc218944605a7391aed0d5/pkgs/applications/editors/jetbrains/bin/linux.nix#L63)时，有一个操作将vmopts放入vmoptsFile，最后这个变量将在wrapProgram --set-default ${vmoptsIDE}\_VM\_OPTIONS ${vmoptsFile}中使用。不知道为什么我 overrideAttrs 的这个变量无法被插入到 wrapPrograms 中去。还有在这种情况下，我如何调试它？
我已经尝试在nix repl中加载flake，以及类似outputs. homemetration的东西。jacky@ANixOS但我不能进一步调试了。

--prefix LD_LIBRARY_PATH : "${lib.makeLibraryPath extraLdPath}" \
${lib.concatStringsSep " " extraWrapperArgs} \
--set-default JDK_HOME "$jdk" \
--set-default ANDROID_JAVA_HOME "$jdk" \

--set-default JETBRAINS_CLIENT_JDK "$jdk" \
--set-default ${hiName}_JDK "$jdk" \
--set-default LOCALE_ARCHIVE "${glibcLocales}/lib/locale/locale-archive" \
--set-default ${vmoptsIDE}_VM_OPTIONS ${vmoptsFile}
```
1. 这个vmopts已经在pkgs/top-level/all-packages.nix和`vmopts = config.jetbrains.vmopts或null;`中定义了，我不知道如何使用这个（在STFW之后没找到任何相关的代码）。

- 最终根据 [NikSOS](https://github.com/NikSneMC/NikSOS/) 提供的信息，采用了 override vmopt 并且通过 HM modules 将对应的操作包装成为一个“勉强”能说可复用的modules。
- 该 Ides 方法需要在特定 HM 版本（23.11以上）和特定软件包版本 2024.1.1 才被支持（见[软件包查询器](https://lazamar.co.uk/nix-versions/?channel=nixpkgs-unstable&package=idea-ultimate))
- 经过简单的包装，以及通过下面的方法简单的将 cfg.packages 挨个进行 override，将传入的结果挨个传入到 programs.jetbrains-remote 中。
-
````auto
cfg = config.programs.jetbrains;
patchIDEs = builtins.map (ide: ide.overrideAttrs {
vmopts = ''
--add-opens=java.base/jdk.internal.org.objectweb.asm=ALL-UNNAMED
--add-opens=java.base/jdk.internal.org.objectweb.asm.tree=ALL-UNNAMED
-javaagent:${pkgs.ja-netfilter}/ja-netfilter.jar=jetbrains
'';
});
...
config = lib.mkIf (cfg.enable && cfg.packages != []) {
programs.jetbrains-remote = {
enable = true;
ides = patchIDEs cfg.packages;
};
home.packages = (patchIDEs cfg.packages) ++ [pkgs.ja-netfilter];
};
```
````
- 然后在 flake 中通过引入 overlays 的方式实现对于特定版本包的访问：
- 添加inputs`nixpkgs-idea-20240101.url = "github:nixos/nixpkgs/57610d2f8f0937f39dbd72251e9614b1561942d8";`
- 由于根据 nix-starter-config 的设计，overlays 分为三种不同的类别(additions, modification, unstable-packages) 分别在 overlays/default.nix 中定义，并且在特定配置文件中通过 `outputs.overlays.additions/.../...` 进行引入。
- 此处考虑到虽然当前的模板分类不提供该方法，但是没有必要额外添加有关修订，因此简单将对于该包的复用合并到unstable-packages中。
-
```auto
nixpkgs-idea-20240101 = import inputs.nixpkgs-idea-20240101 {
system = final.system;
config.allowUnfree = true;
};
```
- 然后根据既定规则在使用本模块的 HM 配置中引入 `outputs.homeManagerModules.jetbrains` 模块，并且传入对应的软件包。
-
```nix
programs.jetbrains = {
enable = true;
packages = with pkgs.nixpkgs-idea-20240101.jetbrains; [ # Only support this version
idea-ultimate
];
};
```
- 最终，成功替换密钥认证为 3.jetbrains.in 服务器所提供的版本
