File template variables
A file template can contain variables, which are replaced by their values when the template is applied. A variable is a string that starts with a dollar sign $ followed by the variable name. The variable name may optionally be enclosed in curly braces. For example: $MyVariable and ${MyVariable} are different notations of the same variable.
Document template variables
Document templates can contain variables, after applying a template, these variables can be replaced by their values. A variable is a string that connected after the variable name begins with a dollar symbol "$." Variable name may be selected by braces "{}" enclosed. Such as: $ MyVariable and $ {MyVariable} variables are the same but different signs.
Predefined template variables
The following predefined variables can be used in file templates:
| Variable | Description |
| ${DATE} | Current system date |
| ${DAY} | Current day of the month |
| ${DS} | Dollar sign $. This variable is used to escape the dollar character, so that it is not treated as a prefix of a template variable. |
| ${FILE_NAME} | Name of the new file |
| ${HOUR} | Current hour |
| ${MINUTE} | Current minute |
| ${MONTH} | Current month |
| ${MONTH_NAME_FULL} | Full name of the current month(January, February, and so on) |
| ${MONTH_NAME_SHORT} | First three letters of the current month name(Jan, Feb, and so on) |
| ${NAME} | Name of the new entity(file, class, interface, and so on) |
| ${ORGANIZATION_NAME} | Name of your organization specified in the project settings(Ctrl+Shift+Alt+S) |
| ${PRODUCT_NAME} | Name of the IDE(for example, PyCharm) |
| ${PROJECT_NAME} | Name of the current project |
| ${TIME} | Current system time |
| ${USER} | Login name of the current user |
| ${YEAR} | Current year |
Default template variables
The table to the predefined variables available in the document template:
| variable | description |
| ${DATE} | The current system date |
| ${DAY} | The current day of a month |
| ${DS} | Dollar symbol $. This variable is used to escape the dollar character, so it will not be treated as the prefix template variables |
| ${FILE_NAME} | The name of the new file |
| ${HOUR} | Current hours |
| ${MINUTE} | Current minute |
| ${MONTH} | Current month |
| ${MONTH_NAME_FULL} | The full name of the current month (January, February, and so on) |
| ${MONTH_NAME_SHORT} | The first three letters of the name of the current month (Jan, Feb, and so on) |
| ${NAME} | The name of the new entity (document, classes, interfaces, and so on) |
| ${ORGANIZATION_NAME} | Specified in the project settings Name (Ctrl + Shift + Alt + S) |
| ${PRODUCT_NAME} | IDE name (eg: PyCharm) |
| ${PROJECT_NAME} | The current project name |
| ${TIME} | The current system time |
| ${USER} | The current user's login name |
| ${YEAR} | Current year |
Custom template variables
Besides predefined template variables, it is possible to specify custom variables. If necessary, you can define the values of custom variables right in the template using the #set directive.
For example, if you want to use your full name instead of your login name defined through the predefined variable ${USER}, use the following construct:
#set( $MyName = "John Smith" )
If the value of a variable is not defined in the template, PyCharm will ask you to specify it when the template is applied.
Custom template variables
除了预设定的模板变量，定制的变量也是可以的。必要的话，你可以在模板中使用#set指令自定义一些变量的值。
举例，如果你想通过预设变量${USER}用你的全名替代你的登录名，就使用下面的语法结构：
#set( $MyName = "John Smith" )
在模板中，如果变量的值没有定义的话，当模板应用后PyCharm会要求你进行设定。
