This is a general guide for using SpaceVim as a Perl IDE, including layer configuration and usage.
Each of the following sections will be covered:
<!-- vim-markdown-toc GFM -->
- [Enable language layer](#enable-language-layer)
- [Code completion](#code-completion)
- [Syntax linting](#syntax-linting)
- [Jump to test file](#jump-to-test-file)
- [running code](#running-code)
- [Code formatting](#code-formatting)
- [REPL support](#repl-support)
<!-- vim-markdown-toc -->
### Enable language layer
To add Perl language support in SpaceVim, you need to enable the `lang#perl` layer. Press `SPC f v d` to open
SpaceVim configuration file, and add the following snippet:
```toml
[[layers]]
name = "lang#perl"
```
For more info, you can read the [lang#perl](../layers/lang/perl/) layer documentation.
### Code completion
`lang#perl` layer will load the Perl plugin automatically, unless it's overriden in your `init.toml`.
The completion menu will be opened as you type.
### Syntax linting
The checkers layer is enabled by default. This layer provides asynchronous syntax linting via [neomake](https://github.com/neomake/neomake).
It will run Perl and perlcritic asynchronously.
Install perlcritic via cpan:
```sh
cpanm Perl::Critic
```
### Jump to test file
SpaceVim use built-in plugin to manager the files in a project, you can add a `.project_alt.json` to the root of your project with the following content:
```json
{
"src/*.pl": {"alternate": "test/{}.pl"},
"test/*.pl": {"alternate": "src/{}.pl"}
}
```
With this configuration, you can jump between the source code and test file via command `:A`
### running code
To run current script, you can press `SPC l r`, and a split window
will be openen, the output of the script will be shown in this window.
It is running asynchronously, and will not block your Vim.
### Code formatting
The format layer is also enabled by default. With this layer you can use key binding `SPC b f` to format current buffer.
Before using this feature, please install perltidy:
```sh
cpanm Perl::Tidy
```
### REPL support
Start a `perli` or `perl -del` inferior REPL process with `SPC l s i`. After the REPL process being started, you can
send code to inferior process. All key bindings prefix with `SPC l s`, including sending line, sending selection or even
send whole buffer.
