# argh command line parser
|
|
|
|
## background
|
|
|
|
The Go standard library [flag](https://pkg.go.dev/flag) way of doing things has long been
|
|
a source of frustration while implementing and maintaining the
|
|
[urfave/cli](https://github.com/urfave/cli) library. [Many alternate parsers
|
|
exist](https://github.com/avelino/awesome-go#standard-cli), including:
|
|
|
|
- [pflag](https://github.com/spf13/pflag)
|
|
- [argparse](https://github.com/akamensky/argparse)
|
|
|
|
In addition to these other implementations, I also got some help via [this
|
|
oldie](https://blog.gopheracademy.com/advent-2014/parsers-lexers/) and the Go standard
|
|
library [parser](https://pkg.go.dev/go/parser).
|
|
|
|
## goals
|
|
|
|
- get a better understanding of the whole problem space
|
|
- support both POSIX-y and Windows-y styles
|
|
- build a printable/JSON-able parse tree
|
|
- support rich error reporting
|
|
- support event-like reactive parsing
