The origin of these ideas is not revealgo

App::revealup

• The origin of revealgo
• One of Perl CPAN modules
• https://metacpan.org/pod/App::revealup
• Written by me :)

Perl to Go

• Make it more simple
• Deplicate subcommand serve/export
• Use the standard HTTP and Template libraries
• 610 lines => 202 lines
• There is golang.org/x/tools/present

Libraries

• Plack::Runner => ServeHTTP + CLI
• Getopt::Long => github.com/jessevdk/go-flags
• Text::MicroTemplate => text/template

How about Go?

• Easy to install with go get or using the binary
• Standard libraries are modern for web apps
• Static types and compiler
• But we can write the code like script languages
