sql-gen-doc

A tool to automatically generate sql documentation.

Installation

  go get -u github.com/ntindall/sql-gen-doc

Usage

sql-gen-doc will connect to a database and generate a markdown table corresponding to the current state of each table in the database. This is useful for databases that undergo frequent migrations. You can set up your CI to run this tool whenever a new migration is added.

$ ./bin/sql-gen-doc --help
Usage of ./bin/sql-gen-doc:
  -dsn string
      a data source name for the database, e.g. user:password@tcp(mysql:3306)/database_name
  -o string
      the outfile to write the documentation to, if no outfile is specified, the output is written to stdout

$ ./bin/sql-gen-doc -dsn 'user:password@tcp(localhost:3306)/database_to_generate' -out outfile.md

Additionally, the markdown file can be annotated with comments in order to have sql-gen-doc insert the table into a specific location in an existing file. For this to work, just add these comments to your markdown file and then specify it as the outfile via the command line flag.

# fake markdown

<!-- sql-gen-doc BEGIN -->
database documentation will go here!
<!-- sql-gen-doc END -->

more documentation!
