Plugin MyMap

MyMap can help you custom activating information in JetBrains IDE. Here is the config file:

[MyMap]
EQUAL,licenseeName->jb-netfilter
EQUAL,gracePeriodDays->100000
EQUAL,paidUpTo->2099-12-31

You should change jb-netfilter to your user name, change 2099-12-31 to the time you want to show.

JB_DEFAULT

No stable version currently supports this feature.

You can see JB_DEFAULT in our config files. This expression allows the plugin to automatically adjust the configuration to the corresponding one suitable for activating JetBrains IDE, and does not conflict with other configurations of the same plugin.

For example, in conf/url.conf we have:

[URL]
PREFIX,JB_DEFAULT

it's equal to:

[URL]
PREFIX,https://account.jetbrains.com/lservice/rpc/validateKey.action

which can block the IDE activation verification.

In power.conf, you are allowed to configure JB_DEFAULT twice. The first JB_DEFAULT is equal to: 12050631930840502994303310119825952355765... , the second JB_DEFAULT is euqal to: 80286595538361199015936553116778652906723....

If there's one invalid JB_DEFAULT config, the other can be used as a backup.
