+## Building
+
+Make sure the submodules are checked out:
+
+```sh
+git submodule update --init
+```
+
+Build:
+
+```sh
+make uwu_include_path=/path/to/uwulang/repo
+```
## Modules
-### `nolambda:flow`
+Note: The module `global` is not implemented yet.
+
+### `flow`
-- `nolambda:flow:linear`: Accepts an arbitrary number of arguments of arbitrary type, but at least one and evaulates all of them in order. Returns the last argument.
-- `nolambda:flow:error`: Accepts an arbitrary value as $0, prints it to stderr appending a newline and exits the program with failure. Returns `:nil:nil` in theory.
+- `flow.linear`: Accepts an arbitrary number of arguments of arbitrary type, but at least one and evaulates all of them in order. Returns the last argument.
+- `flow.error`: Accepts an arbitrary type as $0, prints it to stderr appending a newline and exits the program with failure. Returns `nil.nil` in theory.
-### `nolambda:io`
+### `io`
-- `nolambda:io:print`: Accepts an arbitrary value as $0 and prints it to stdout, followed by a newline. Returns $0.
-- `nolambda:io:scan`: Reads a line from stdin and returns it as a string, without the newline character at the end. If $0 is given, it is used as a prompt (after converting to string).
+- `io.print`: Accepts an arbitrary type as $0 and prints it to stdout, followed by a newline. Returns $0.
+- `io.scan`: Reads a line from stdin and returns it as a string, without the newline character at the end. If $0 is given, it is used as a prompt (after converting to string).
-### `nolambda:fs`
+### `fs`
Note: all file paths are relative to the _directory the program was started from_.
-- `nolambda:fs:read`: Accepts a file name (arbirary value, used as string) as $0 and returns it's contents as a string. Causes an error if the file does not exist.
-- `nolambda:fs:write`: Accepts a file name (arbirary value, used as string) as $0 and overwrites it with the contents in $1 (arbirary value, used as string). Causes an error if the file could not be written. Returns `:bool:true` if the file was freshly created, `:bool:false` if it was overwritten.
-- `nolambda:fs:remove`: Accepts a file name (arbirary value, used as string) as $0 and removes it from the file system. Causes an error if the file could not be removed, but does not cause an error if the file does not exist. Returns `:bool:true` if the file existed and was removed, `:bool:false` otherwise.
-- `nolambda:fs:exists`: Accepts a file name (arbirary value, used as string) as $0 and returns `:bool:true` if it exists, `:bool:fase` else.
+- `fs.read`: Accepts a file name (arbirary value, converted to string) as $0 and returns it's contents as a string. Causes an error if the file does not exist.
+- `fs.write`: Accepts a file name (arbirary value, converted to string) as $0 and overwrites it with the contents in $1 (arbirary value, converted to string). Causes an error if the file could not be written. Returns `nil.nil`.
+- `fs.remove`: Accepts an arbitrary number of file names (arbirary type, converted to string), but at least one and unlinks them from the file system (the files can also be a directories). Causes an error if one of the file could not be removed, or if some or all of the files did not exist in the first place. Returns `nil.nil`.
+- `fs.exists`: Accepts an arbitrary number of file names (arbirary type, converted to string), but at least one and returns `bool.true` if all of them exist, `bool.false` else.
-### `nolambda:os`
+### `os`
-- `nolambda:os:exit`: Optionally takes an exit code (integer) as $0 and exits the program with the given exit code, or 0 if no exit code was given. Returns `:nil:nil` in theory.
-- `nolambda:os:sleep`: Takes an integer as $0 and pauses the execution of the program for $1 milliseconds. Returns `:nil:nil`.
-- `nolambda:os:execute`: Takes a command (arbirary value, used as string) as $0 and executes it as a shell command. Returns the exit code of the command as an integer.
-- `nolambda:os:time`: Returns the current unix time as an integer.
+- `os.exit`: Optionally takes an exit code (integer) as $0 and exits the program with the given exit code, or 0 if no exit code was given. Returns `nil.nil` in theory.
+- `os.sleep`: Takes an integer as $0 and pauses the execution of the program for $1 milliseconds. Returns `nil.nil`.
+- `os.execute`: Takes a command (arbirary value, converted to string) as $0 and executes it as a shell command. Returns the exit code of the command as an integer.
+- `os.time`: Returns the current unix millis as an integer.
-### `nolambda:global`
+### `global`
-- `nolambda:global:set`: Creates or overwrites a global variable named $0 (arbirary value, used as string) and puts the contents of $1 (arbitrary type) into it. Returns `:bool:false` if the variable existed previously and was updated, `:bool:true` if it was created.
-- `nolambda:global:get`: Returns the global variable named $0 (arbirary value, used as string). Causes an error if the variable does not exist.
-- `nolambda:global:exists`: Returns `:bool:true` if the global variable named $0 (arbirary value, used as string) exists, `:bool:false` else.
-- `nolambda:global:delete`: Deletes the global variable named $0 (arbirary value, used as string). Returns `:bool:true` if the variable existed previously, `:bool:false` else.
+- `global.set`: Creates or overwrites a global variable named $0 (arbirary value, converted to string) and puts the contents of $1 (arbitrary type) into it. Returns `bool.false` if the variable existed previously and was updated, `bool.true` if it was created.
+- `global.get`: Returns the global variable named $0 (arbirary value, converted to string). Causes an error if the variable does not exist.
+- `global.exists`: Returns `bool.true` if the global variable named $0 (arbirary value, converted to string) exists, `bool.false` else.
+- `global.delete`: Deletes the global variable named $0 (arbirary value, converted to string). Returns `bool.true` if the variable existed previously, `bool.false` else.
-### `nolambda:random`
+### `random`
-- `nolambda:random:random`: Returns a pseudorandom integer between $0 (integer) and $1 (integer). The upper bound is exclusive, the lower bound inclusive. Causes an error if the range is bigger than `nolambda:random:max`.
-- `nolambda:random:max`: Returns RAND_MAX, which is usually 32767.
-- `nolambda:random:seed`: Sets the random seed to $0 (integer) and returns `:nil:nil`.
+- `random.random`: Returns a pseudorandom integer between $0 (integer) and $1 (integer). The range is inclusive on both boundse. Causes an error if the range is bigger than `random.max` or empty.
+- `random.max`: Returns RAND_MAX.
+- `random.seed`: Sets the random seed to $0 (integer) and returns `nil.nil`.
