Bash is the GNU Project’s shell for command-line interaction and shell scripting.
Bashly
Bashly generates Bash command-line applications from a configuration, using a Ruby command-line tool.
About Bashly
Bashly is a Ruby command-line tool that generates Bash scripts from a YAML file describing commands, subcommands, arguments and flags. Running bashly init creates a sample configuration, and bashly generate produces a standalone script that parses and validates input, shows help messages, and runs separate code files for each command.
The generated script does not run when the command line is invalid. Edited command code can be merged back into the output, and Bashly can add optional library functions and auto-generated markdown and man page documentation.
Key features
- Generate standalone Bash script from YAML configuration
- Parse required or optional arguments, flags and subcommands
- Generate usage texts and help screens for subcommands
- Block script execution unless command line is valid
- Merge separate per-command code files into final script
- Auto-generate markdown and man page documentation
