# 开发
## 配置文件
API Key 保存在 `C:\Users\[user]\.rain\config.json` 中,配置文件格式示例:
```json
{
"api_key": "xxxxxxxxxx",
"servers": [
{ "id": "123456", "name": "my-server" },
{ "id": "789012", "name": "production" }
]
}
```
## 开发环境依赖
```cmd
pip install requests
```
## 打包
```cmd
nuitka --standalone --windows-console-mode=force --include-package=charset_normalizer --output-filename=rain.exe --windows-icon-from-ico=ico.ico 1.py
```
## 安装包
[Inno Setup](https://jrsoftware.org/isinfo.php)是一个非常好用的安装包制作软件。您可以参考以下步骤编辑iss脚本为安装包添加"添加到用户环境变量 PATH"选项:
2026-04-06 08:54:29 +08:00
1.`[Setup]`中,添加`gesEnvironment=yes`
2.`[Tasks]`中,添加选项
```
Name: "addtopath"; Description: "添加到用户环境变量 PATH"; GroupDescription: "其他任务:"; Flags: unchecked
```
3. 在任意位置添加以下脚本
```
[Registry]
; 仅当用户勾选 addtopath 且路径不存在时才添加
Root: HKCU; Subkey: "Environment"; ValueType: expandsz; ValueName: "Path"; \
ValueData: "{olddata};{app}"; Check: NeedsAddPath(ExpandConstant('{app}')); \
Tasks: addtopath
[Code]
const
EnvironmentKey = 'Environment';
// 检查路径是否已存在于 PATH 中
function NeedsAddPath(Param: string): boolean;
var
OrigPath: string;
begin
if not RegQueryStringValue(HKEY_CURRENT_USER, EnvironmentKey, 'Path', OrigPath) then
begin
Result := True;
exit;
end;
// 前后加分号判断,避免误匹配
Result := Pos(';' + Param + ';', ';' + OrigPath + ';') = 0;
end;
// 从 PATH 中移除指定路径(卸载时调用,幂等操作)
procedure RemovePath(Path: string);
var
Paths: string;
P: Integer;
begin
if not RegQueryStringValue(HKEY_CURRENT_USER, EnvironmentKey, 'Path', Paths) then
exit;
// 确保路径前后有分号进行匹配
P := Pos(';' + Path + ';', ';' + Paths + ';');
if P = 0 then exit;
if P > 1 then P := P - 1;
Delete(Paths, P, Length(Path) + 1);
// 清理首尾可能残留的分号
while (Length(Paths) > 0) and (Paths[1] = ';') do Delete(Paths, 1, 1);
while (Length(Paths) > 0) and (Paths[Length(Paths)] = ';') do Delete(Paths, Length(Paths), 1);
// 如果 PATH 变为空字符串,则删除该值;否则写入新值
if Paths = '' then
RegDeleteValue(HKEY_CURRENT_USER, EnvironmentKey, 'Path')
else
RegWriteStringValue(HKEY_CURRENT_USER, EnvironmentKey, 'Path', Paths);
end;
// 卸载时自动清理 PATH
procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
begin
if CurUninstallStep = usUninstall then
RemovePath(ExpandConstant('{app}'));
end;
```
