DIRAC cfg文件的解析器

diraccfg为DIRAC及其相关项目使用的配置文件提供了一个解析器。

安装

pip install diraccfg

命令行使用

diraccfg的命令行模式主要用于将配置转换为JSON文件，然后可以使用标准工具（如jq）进行处理。

以下示例使用以下配置文件运行

DefaultModules = DIRAC
Sources
{
  DIRAC = git://github.com/DIRACGrid/DIRAC.git
}
Releases
{
  integration
  {
    Modules = DIRAC, WebAppDIRAC, VMDIRAC
    Externals = v6r6p8
    DIRACOS = master
  }
  v7r0-pre19
  {
    Modules = DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r5, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1
    DIRACOS = master
  }
  v6r22p2
  {
    Modules = DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1
    Externals = v6r6p8
    DIRACOS = v1r3
  }
  v6r22p1
  {
    Modules = DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1
    Externals = v6r6p8
    DIRACOS = v1r3
  }
}

以JSON格式打印

$ diraccfg as-json example.cfg
{"DefaultModules": "DIRAC", "Sources": {"DIRAC": "git://github.com/DIRACGrid/DIRAC.git"}, "Releases": {"integration": {"Modules": "DIRAC, WebAppDIRAC, VMDIRAC", "Externals": "v6r6p8", "DIRACOS": "master"}, "v7r0-pre19": {"Modules": "DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r5, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1", "DIRACOS": "master"}, "v6r22p2": {"Modules": "DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1", "Externals": "v6r6p8", "DIRACOS": "v1r3"}, "v6r22p1": {"Modules": "DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1", "Externals": "v6r6p8", "DIRACOS": "v1r3"}}}

使用jq提取可用版本

$ diraccfg as-json example.cfg | jq '.Releases'
{
  "integration": {
    "Modules": "DIRAC, WebAppDIRAC, VMDIRAC",
    "Externals": "v6r6p8",
    "DIRACOS": "master"
  },
  "v7r0-pre19": {
    "Modules": "DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r5, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1",
    "DIRACOS": "master"
  },
  "v6r22p2": {
    "Modules": "DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1",
    "Externals": "v6r6p8",
    "DIRACOS": "v1r3"
  },
  "v6r22p1": {
    "Modules": "DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1",
    "Externals": "v6r6p8",
    "DIRACOS": "v1r3"
  }
}

获取稳定版本号的排序列表

$ diraccfg as-json example.cfg | jq '.Releases' | diraccfg sort-versions
["v6r22p2", "v6r22p1"]

获取包括预发布版的版本号排序列表

$ diraccfg as-json example.cfg | jq '.Releases' | diraccfg sort-versions --allow-pre-releases
["v7r0-pre19", "v6r22p2", "v6r22p1"]

查找最新版本

$ diraccfg as-json example.cfg | jq '.Releases' | diraccfg sort-versions | jq -r '.[0]'
v6r22p2

$ diraccfg as-json example.cfg | jq '.Releases' | diraccfg sort-versions --allow-pre-releases | jq -r '.[0]'
v7r0-pre19
