Glob Pattern

Glob pattern are used in Tabulify to select objects such as :

• connection
• resource (in data selector)
• or configuration

Wildcard support

The following wildcard are supported in order to define the glob pattern:

• * that matches every characters
• ** matches all container (directories/schema). Use for recursive search (for instance **/foo.md will search all foo.md files in all sub directories)
• ? that matches a single character
• [] that matches a class of character (Example: [0-9] matches all digit)
• [!] that does not match a character in the class of character. (Example: [!0-9] will not match a digit)
• {pattern1,pattern2,..} to match a collection of sub-pattern (Example: {temp*,tmp*} matches all data resource name that begins with temp or tmp). It creates also a group for back-referencing.

Back-referencing

When data resources are selected via globbing, they get extra numeric variables that captures the text that matches.

ie:

• the variable 1 is the text captured by the first glob pattern
• the variable 2 is the text captured by the second glob pattern
• and so on.

You can use this extra variable in:

• a template name
• a target uri

Example with the data list command that:

• selects the table that starts with web on a tpcds schema
• shows the logical and the 1 first back-reference value

tabli data list -a logicalName -a 1 web_*@tpcds

logicalName   1
-----------   -------
web_page      page
web_returns   returns
web_sales     sales
web_site      site
