$next clj

($next)

Bump the index and produce a '$n' string.

$wrap clj

($wrap f)

Wrap a function into the binding macro to make the $next function work.

*$* clj

The current index of $1, ... $n placeholders.

def-db-fns clj

(def-db-fns file)

(def-db-fns file defaults)

(def-db-fns file defaults options)

Read and inject functions from a .sql file. Acts like hugsql.core/def-db-fns but overrides some internal steps.

It automatically creates a PG2-related adapter and assigns it to the newly created functions.

Arguments:

• file is either a string, or a resource, or a file object which is the source of .sql payload;

• defaults is a map of arguments what will be passed to pg.core/execute on each call. See the PG2 readme file for more details;

• options is map of HugSQL options. It's unlikely you will need to use it.

Once this function is called, functions from the .sql file appear in the current namespace. Each function has the following signature:

[db] [db params] [db params opt], where:

• db is either a connection config map, or a connection, or a pool. If it was config map, the connection gets closed afterwards. When it's a pool, the connection is borrowed from it and then returned;

• params is the standard HugSQL map of SQL parameters;

• opt: pg2-specific arguments that are passed to the pg.core/execute function. They will override the defaults passed to the def-db-fns call.

intern-function clj

(intern-function fn-name fn-meta fn-obj)

Inject a function produced by HugSQL into the current namespace.

make-adapter clj

(make-adapter)

(make-adapter defaults)

Initiate an adapter object. The defaults, when specified, are passed to the pg.core/execute function.

wrap-signature clj

(wrap-signature f)

Slightly correct the signature of a function produced by HugSQL. Namely, pass pg.core/execute parameters through a dedicated key to prevent merging them with something else.
