# rebar3_typer
A rebar3 plugin wrapper around [TypEr](https://www.erlang.org/doc/man/typer.html)
## Build and Test
```sh
$ rebar3 test
```
## Use
Add the plugin to your rebar config:
```erlang
{project_plugins, [{rebar3_typer, "~> 0.0.0"}]}.
```
Then just call your plugin directly in an existing application:
```sh
$ rebar3 typer
===> Fetching rebar3_typer
===> Compiling rebar3_typer
```
## Configuration
You can basically use the same command-line options as you can use with the original TypEr:
```man
Usage: rebar3 typer [-r ] [-f ]
[--show []]
[--show-exported []]
[--show_exported []]
[--show-success-typings []]
[--show_success_typings []]
[--annotate []]
[--annotate-inc-files []]
[--annotate-in-place []]
[--annotate_in_place []]
[--no_spec []] [--edoc []]
[--plt ] [-T ]
-r Search comma-separated directories recursively
for .erl files below them.
-f Files to analyze.
--show Print type specifications for all functions on
stdout. [default: false]
--show-exported Same as --show, but print specifications for
exported functions only. Specs are displayed
sorted alphabetically on the function's name.
[default: false]
--show_exported Same as --show-exported. [default: false]
--show-success-typings Show the success typings inferred by Dialyzer /
Typer. This is an undocumented option. [default:
false]
--show_success_typings Same as --show-success-typings. This is an
undocumented option. [default: false]
--annotate Annotate the specified files with type
specifications. [default: false]
--annotate-inc-files Same as --annotate but annotates all -include()
files as well as all .erl files. (Use this
option with caution - it has not been tested
much). [default: false]
--annotate-in-place Annotate directly on the source code files,
instead of dumping the annotated files in a
different directory. [default: false]
--annotate_in_place Same as --annotate-in-place. [default: false]
--no_spec Ignore the specs from the files. This is an
undocumented option. [default: false]
--edoc Print type information as Edoc @spec comments,
not as type specs. [default: false]
--plt Use the specified dialyzer PLT file rather than
the default one from the profile's base
directory.
-T The specified file(s) already contain type
specifications and these are to be trusted in
order to print specs for the rest of the files.
(Multiple files or dirs, separated by commas,
can be specified.)
```
You can also put those options directly in your `rebar.config` file:
```erlang
{typer,
[{mode, show}, %% Results mode: show | show_exported | annotate | annotate_inc_files | annotate_in_place
{edoc, false}, %% Print type information as Edoc @spec comments, not as type specs.
{plt, "/path/to/plt"}, %% Use the specified dialyzer PLT file rather than the default one.
{show_success_typings, false}, %% Show the success typings inferred by Dialyzer / Typer.
{no_spec, false}, %% Ignore existing function specs.
{recursive, ["d1/", "d2/"]}, %% Search directories recursively for .erl files.
{files, ["foo.erl"]}, %% Analyze listed .erl files, non-recursively.
{typespec_files, ["f1", "f2"]} %% The specified file(s) already contain type specifications.
