Ben KraftandGitHub 2eba9a2c30 Reorganize documentation to make room to grow (#84)
## Summary:
In this commit I reorganize much of our documentation into a new `docs`
directory, where there will hopefully be more room to grow and to
organize things in a user-friendly way.  There's almost no net-new
documentation, although of course it's a great time to review it anyway.

In particular:
- I moved the documentation for the `genqlient.yaml` config file into an
  example file instead of GoDoc (which now just points to the example
  file); I think this will be a lot clearer for casual users.
- I moved the documentation for the `@genqlient` directive out of GoDoc
  and into a GraphQL schema file (since while it's a comment it's all
  real syntax), likewise, and made the `GenqlientDirective` type private
  (since there's now nothing useful to do with it).
- I moved `DESIGN.md` and the logo into `docs/` (just to keep the
  toplevel a bit cleaner), and separated the Contributing section of the
  README into `docs/CONTRIBUTING.md` (which github will automatically
  link on various issue and PR pages).

This leaves it so that:
- README.md is the only documentation at the toplevel (and will become
  just the high-level introduction as I add more user docs to `docs/`)
- GoDoc is only documentation for if you want to call genqlient
  programmatically (which is fairly limited as the API surface is quite
  small: it's now just Main, Generate, and Config, plus a constructor, a
  single method, and a bunch of fields on the latter)

In future commits, I'll add some more new documentation to the `docs`
directory.

## Test plan:
make check (and read the docs)

# genqlient.yaml is genqlient's configuration file. This genqlient.yaml is an
# example; use `go run github.com/Khan/genqlient --init` to generate a simple
# starting point.
# The filename with the GraphQL schema (in SDL format), relative to
# genqlient.yaml.
schema: schema.graphql
# Filenames or globs with the operations for which to generate code, relative
# to genqlient.yaml.
#
# These may be .graphql files, containing the queries in SDL format, or
# Go files, in which case any string-literal starting with (optional
# whitespace and) the string "# @genqlient" will be extracted as a query.
operations:
- genqlient.graphql
- "pkg/*.go"
# The filename to which to write the generated code, relative to
# genqlient.yaml.
generated: generated/genqlient.go
# The package name for the output code; defaults to the directory name of
# the generated-code file.
package: mygenerated
# If set, a file at this path (relative to genqlient.yaml) will be generated
# containing the exact operations that genqlient will send to the server.
#
# This is useful for systems which require queries to be explicitly
# safelisted (e.g. [1]), especially for cases like queries involving fragments
# where it may not exactly match the input queries, or for other static
# analysis. The JSON is an object of the form
# {"operations": [{
# "operationName": "operationname",
# "query": "query operationName { ... }",
# "sourceLocation": "myqueriesfile.graphql",
# }]}
# Keys may be added in the future.
#
# By default, no such file is written.

export_operations: operations.json
# Set to the fully-qualified name of a Go type which generated helpers
# should accept and use as the context.Context for HTTP requests.
#
# Defaults to context.Context; set to "-" to omit context entirely (i.e.
# use context.Background()). Must be a type which implements
# context.Context.
context_type: context.Context
# If set, a function to get a graphql.Client, perhaps from the context.
# By default, the client must be passed explicitly to each genqlient
# generated query-helper.
#
# This is useful if you have a shared client, either a global, or
# available from context, and don't want to pass it explicitly. In this
# case the signature of the genqlient-generated helpers will omit the
# `graphql.Context` and they will call this function instead.
#
# Must be the fully-qualified name of a function which accepts a context
# (of the type configured as ContextType (above), which defaults to
# `context.Context`, or a function of no arguments if ContextType is set
# to the empty string) and returns (graphql.Client, error). If the
# client-getter returns an error, the helper will return the error
# without making a query.
client_getter: "github.com/you/yourpkg.GetClient"
# A map from GraphQL type name to Go fully-qualified type name to override
# the Go type genqlient will use for this GraphQL type.
#
# This is primarily used for custom scalars, or to map builtin scalars to
# a nonstandard type. By default, builtin scalars are mapped to the
# obvious Go types (String and ID to string, Int to int, Float to float64,
# and Boolean to bool), but this setting will extend or override those
# mappings.
#
# genqlient does not validate these types in any way; they must define
# whatever logic is needed (MarshalJSON/UnmarshalJSON or JSON tags) to
# convert to/from JSON. For this reason, it's not recommended to use this
# setting to map object, interface, or union types, because nothing
# guarantees that the fields requested in the query match those present in
# the Go type.
#
# To get equivalent behavior in just one query, use @genqlient(bind: ...);
# see genqlient_directive.graphql for more details.
bindings:
# To bind a scalar:
DateTime:
# The fully-qualified name of the Go type to which to bind. For example:
# time.Time
# map[string]interface{}
# github.com/you/yourpkg/subpkg.MyType
type: time.Time
# To bind an object type:
MyType:
type: github.com/you/yourpkg.GoType
# If set, a GraphQL selection which must exactly match the fields
# requested whenever this type is used. Only applies if the GraphQL type
# is a composite output type (object, interface, or union).
#
# This is useful if Type is a struct whose UnmarshalJSON or other methods
# expect that you requested certain fields. For example, given the below
# config, genqlient will reject if you make a query
# { fieldOfMytype { id title } }
# The fields must match exactly, including the ordering: "{ name id }"
# will be rejected. But the arguments and directives, if any, need not
# match.
#
# TODO(benkraft): Also add ExpectIncludesFields and ExpectSubsetOfFields,
# or something, if you want to say, for example, that you have to request
# certain fields but others are optional.
