Automatic table import

Each new table is added to tables.xlsx, which is a tedious task. In most cases, each excel corresponds to a table, and it is possible to let the tool automatically add the table definition.

Since version v3.0.0, automatic table import is supported. luban will scan the excel table according to the specified rules and automatically add the corresponding table.

Default TableImporter

The default TableImporter is DefaultTableImporter, and the corresponding name is default. If the -x tableImporter.name parameter is not specified, DefaultTableImporter is automatically used.

Default scanning rules

DefaultTableImporter will scan all excel family (xls, xlsx, xlm, csv) files in the luban.conf directory (including subdirectories) whose file names start with #, such as #Item.xlsx, reward/#Reward.xlsx. Use the string after removing the leading '#' character and the file suffix as the valueType of the table, and add Tb to the valueType name as the full name of the table. If the Excel file is in a subdirectory, the subdirectory will be used as the namespace. For example:

• #Item.xlsx generates a table with full_name of TbItem, value_type of Item, and mode=map
• reward/#Reward.xlsx generates a table with full_name of reward.TbReward, value_type of reward.Reward, and mode=map
• item/equip/#Equip.csv generates a table with full_name of item.equip.TbEquip, value_type of item.equip.Equip, and mode=map

Custom import rules

Introduce several definitions:

Variable	Definition
RawFullName	The relative path of all directories in the file is converted into a namespace ('\' or '/' in the path is replaced by '.') and then concatenated with the value of the first Group in the tableImporter.filePattern regular item. Taking filePatter=#(.*) and the file name #Item.xlsx as an example, RawFullName is Item; taking the file name item/#Item.xlsx as an example, RawFullName is item.Item
RawNamespace	The namespace in RawFullName, if RawFullName is item.Item, then RawNamespace is item
RawName	The class name in RawFull, if RawFullName is item.Item, then RawName is Item

Configuration parameters related to custom rules:

Parameter	Required	Description	Example
tableImporter.name	No	TableImporter name, the default implementation is DefaultTableImporter, the name is default. If none is selected, automatic import is disabled	-x tableImporter.name=default
tableImporter.filePattern	No	The file name rule for automatic import (without the file name suffix), the format is a C# regular expression string. The default is #(.*)	-x tableImporter.filePattern=!(.*)
tableImporter.tableNamespaceFormat	No	The format string of the table namespace, the default value is {0}, that is, directly take RawNamespace	-x tableImporter.tableNamespaceFormat=My{0}
tableImporter.tableNameFormat	No	The format string of the table class name, the default value is Tb{0}, that is, take Tb plus RawName	-x tableImporter.tableNameFormat=Cfg{0}
tableImporter.valueTypeNameFormat	No	The format string of the value_type class name, the default value is {0}, that is, take RawName. However, if the table namespace exists, the namespace will be automatically added.	-x tableImporter.valueTypeNameFormat=Va{0}

Implement a custom TableImporter

If the default TableImporter does not meet the requirements, you can also implement a custom TableImporter. Refer to the implementation of src/Luban.Schema.Builtin/DefaultTableImporter.cs.

Limitations

Automatically importing tables can only meet common rules. For more complex input data sources, please manually add them in tables.xlsx.

There are the following limitations:

• Multiple data sources are not supported, that is, multiple excel files are not supported to be exported as one table, for example, #Item_1.xlsx and #Item_2.xlsx are not supported to be automatically exported as one table
• Sheet is not supported to be exported as one table, for example, the equip cell sheet in Item.xlsx is not supported to be automatically exported as one table
• Only map mode is supported, not one or index mode
