Command Line Scripting with Templates
summary
Go templates get extended into a lightweight command-line scripting DSL with a new package published as t4tools that injects functions like table/select/sort/filter and helpers describe/generateUsage so tools can document types and run richer queries. The package composes functions, adds tojson/promote/head/tail/rows/cols, and powers an ELF/Mach-O “dump” utility implemented in about 15 lines that successfully extracts headers, symbols and imports. It claims to reduce boilerplate and avoid fragile hardcoded type help.
