|
### 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.
