如果模板中有 ORPHRASE 且输入文本中有连续空格，python ttp 解析器会忽略行

Question

让人：Windows 10，Python：3.9，TTP：0.8.4

我在TTP​​模板中遇到 orphrase 的问题，以及是否连续存在空白空间字符字符串应该拾取模板。

输入文本：

    vprn 5000122 customer 99999 create
        description "LastMod: Jan 28, 2022 2:33:11 AM"
        vrf-import "VPRN-5000122-IMPORT"
        vrf-export "VPRN-5000122-EXPORT"
        router-id 95.95.95.95
        autonomous-system 5555
        route-distinguisher 4444:8888888
        auto-bind-tunnel
            resolution-filter
                ldp
            exit
            resolution filter
        exit
        interface "*dummy-1* L3 interface"  create
            description "*** single blank-space description ***"
            address 199.199.199.199/32
        exit
        interface "*dummy-2* L3 interface"  create
            description "***  double blank-space description ***"
            address 201.201.201.201/32
        exit
        service-name "dumy-vprn-service"
        no shutdown
    exit

TTP模板：

<group name="service">
<group name="vprn.{{ service_id }}**">
    vprn {{service_id | _start_ }} customer {{customer_id}} create
        description "{{ description | ORPHRASE | default("")}}"
        vrf-import "{{ vrf_import }}"
        vrf-export "{{ vrf_export }}"
        autonomous-system {{ autonous_system }}
        route-distinguisher {{ route_distinguisher }}
    <group name="interface.{{interface_id}}**">
        interface "{{ interface_id | ORPHRASE | _start_ }}" create
            description "{{ description | ORPHRASE }}"
            address {{ ipv4_address }}
            ip-mtu {{ ip_mtu }}
        exit {{ _end_ }}
    </group>
        service-name "{{ service_name }}"
        no shutdown {{ state | set("enabled") | default("disabled") }}
    exit {{ _end_ }}
</group>

解析输出：

{
"5000122": {
    "route_distinguisher": "4444:8888888",
    "autonous_system": "5555",
    "vrf_export": "VPRN-5000122-EXPORT",
    "vrf_import": "VPRN-5000122-IMPORT",
    "description": "LastMod: Jan 28, 2022 2:33:11 AM",
    "customer_id": "99999",
    "state": "enabled",
    "interface": {
        "*dummy-1* L3 interface": {
            "ipv4_address": "199.199.199.199/32",
            "description": "*** single blank-space description ***"
        },
        "*dummy-2* L3 interface": {
            "ipv4_address": "201.201.201.201/32"
        }
    },
    "service_name": "dumy-vprn-service"
}

}

问题： 第二个接口中的描述行未被解析器拾取，因为字符串中的连续空格字符

Answer 1

您可以使用line代替ORPHRASE（在开头和结尾都带有下划线的行）
