I'm trying to make a couple of post requests using -d flag like -d {<body goes here>}

I see that ganda errors out saying Incorrect Usage: flag provided but not defined: -d

cat << EOF > /tmp/list_of_urls_and_values
http://httpbin.org/anything/1 bar 111
http://httpbin.org/anything/2 baz 222
http://httpbin.org/anything/3 qux 333
EOF

cat /tmp/list_of_urls_and_values | ganda -X POST -d '{"first": "%s", "second": "%s"}' | grep -E 'data|url'

That post was written prior to ganda 1.0. I did remove the body template parameter (-d) from ganda as it was limited in how expressive it could be and there are other CLI tools that are better ad

The tour of ganda has some examples, but here's the equivalent way to do the same thing by streaming JSON lines to ganda.

Use jq to create JSON (schema for input JSON) that we can stream to ganda:

cat << EOF | jq -Rc 'split(" ") | {url: .[0], body: {first: .[1], second: .[2]}}'                             
http://httpbin.org/anything/1 bar 111
http://httpbin.org/anything/2 baz 222
http://httpbin.org/anything/3 qux 333
EOF
{"url":"http://httpbin.org/anything/1","body":{"first":"bar","second":"111"}}
{"url":"http://httpbin.org/anything/2","body":{"first":"baz","second":"222"}}
{"url":"http://httpbin.org/anything/3","body":{"first":"qux","second":"333"}}

then with ganda and the grep:

cat << EOF | jq -Rc 'split(" ") | {url: .[0], body: {first: .[1], second: .[2]}}' | ganda | grep -E 'data|url'
http://httpbin.org/anything/1 bar 111
http://httpbin.org/anything/2 baz 222
http://httpbin.org/anything/3 qux 333
EOF
Response: 200 http://httpbin.org/anything/1
  "data": "{\"first\":\"bar\",\"second\":\"111\"}", 
  "url": "http://httpbin.org/anything/1"
  "data": "{\"first\":\"baz\",\"second\":\"222\"}", 
Response: 200 http://httpbin.org/anything/2
  "url": "http://httpbin.org/anything/2"
Response: 200 http://httpbin.org/anything/3
  "data": "{\"first\":\"qux\",\"second\":\"333\"}", 
  "url": "http://httpbin.org/anything/3"

Is it possible to bring back that option? It was very intuitive. I used to get a curl from postman or any other place and used to replace curl with ganda to craft requests by substituting a string in the body.

I haven't used ganda + postman like you're suggesting, so I might not be fully following how the old system was compatible with it. Do curl and postman use that same %s token replacement with the url in the same first position?

I'd lean a lot more into making some pipe utility that can format JSON like ganda now wants but do it in a flexible way. Turning the jq statment I have above into a separate CLI that supports a -d '{body}' command would be pretty easy.

With ganda, I want it to do one thing well: making lots of http requests and handling responses. It was a pretty bad template language that I had in the 0.X ganda days and I'd rather delegate that to tools more custom suited to nice formatting.

If you can show me some commands of how you're taking a curl and turning it into a ganda statement, I'd be interested in seeing that. I might be missing something in the use case.

I threw together a quick golang CLI tool that could be used for generic values like this called gotemplate, it can use all of the various printf style values (so, significantly more control than the 0.x version of ganda had):

cat << EOF | ./gotemplate -d '{"string": "%s", "int": %5d, "left_int": %-5d, "zero_pad": %05d, "float": %8.2f, "left_float": %-8.2f, "generic": %v}'
hello 42 99 7 3.14159 2.718 world
goodnight 1234 5 123 0.1 100.5 3.1415
EOF
{"string": "hello", "int":    42, "left_int": 99   , "zero_pad": 00007, "float":     3.14, "left_float": 2.72    , "generic": world}
{"string": "goodnight", "int":  1234, "left_int": 5    , "zero_pad": 00123, "float":     0.10, "left_float": 100.50  , "generic": 3.1415}

This could be used to generate values that could be passed to ganda, but would also be generically useful for templating stdin and "form filling" values:

cat << EOF | ./gotemplate -d '{"url": "%s", "body": {"first": "%s", "second": %d}}'
http://httpbin.org/anything/1 bar 111
http://httpbin.org/anything/2 baz 222
http://httpbin.org/anything/3 qux 333
EOF
{"url": "http://httpbin.org/anything/1", "body": {"first": "bar", "second": 111}}
{"url": "http://httpbin.org/anything/2", "body": {"first": "baz", "second": 222}}
{"url": "http://httpbin.org/anything/3", "body": {"first": "qux", "second": 333}}
