lrepr
|
Return a string representation of a Lisp object.
Permissible keyword arguments are:
- human_readable: if logical True, print strings without quotations or
escape sequences (default: false)
- print_dup: if logical true, print objects in a way that preserves their
types (default: false)
- print_length: the number of items in a collection which will be printed,
or no limit if bound to a logical falsey value (default: 50)
- print_level: the depth of the object graph to print, starting with 0, or
no limit if bound to a logical falsey value (default: nil)
- print_meta: if logical true, print objects meta in a way that can be
read back by the reader (default: false)
- print_readably: if logical false, print strings and characters with
non-alphanumeric characters converted to escape sequences
(default: true)
Note that this function is not capable of capturing the values bound at
runtime to the basilisp.core dynamic variables which correspond to each
of the keyword arguments to this function. To use a version of lrepr
which does capture those values, call basilisp.lang.runtime.lrepr directly.

_read_unquote
|
Read an unquoted form and handle any special logic of unquoting.
Unquoted forms can take two, well... forms:
`~form` is read as `(unquote form)` and any nested forms are read
literally and passed along to the compiler untouched.
`~@form` is read as `(unquote-splicing form)` which tells the compiler
to splice in the contents of a sequential form such as a list or
vector into the final compiled form. This helps macro writers create
longer forms such as function calls, function bodies, or data structures
with the contents of another collection they have.
