|
|
|
The =gtags= layer is recommended to benefit from better =eldoc= and
|
|
=helm-gtags=.
|
|
|
|
* Install
|
|
** Layer
|
|
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
|
|
add =php= to the existing =dotspacemacs-configuration-layers= list in this
|
|
file.
|
|
|
|
** Backends
|
|
For php you have the choice between a set of possible LSP backends with
|
|
different setup instructions and different capabilities.
|
|
|
|
Note that you'll need to use the =lsp= layer to enable these backends.
|
|
|
|
*** intelephense
|
|
This is the recommended LSP server solution. To activate it set the
|
|
layer variable =php-backend=:
|
|
|
|
#+BEGIN_SRC elisp
|
|
(php :variables php-backend 'lsp)
|
|
#+END_SRC
|
|
|
|
and install the npm server with:
|
|
|
|
#+BEGIN_SRC sh
|
|
npm install -g intelephense
|
|
#+END_SRC
|
|
|
|
You can find further information on the project's [[http://intelephense.net/][website]] and [[https://github.com/bmewburn/vscode-intelephense][GitHub page]].
|
|
|
|
*** php-language-server
|
|
This is an alternative LSP server implementation working on PHP basis rather than nodejs.
|
|
To activate it set the layer variable =php-backend= like for the intelephense backend and
|
|
install the server via [[https://getcomposer.org/][composer]]:
|
|
|
|
#+BEGIN_SRC sh
|
|
composer require felixfbecker/language-server
|
|
composer run-script --working-dir=vendor/felixfbecker/language-server parse-stubs
|
|
#+END_SRC
|
|
|
|
You can find further information on the project's [[https://github.com/felixfbecker/php-language-server%20][GitHub page]].
|
|
|
|
*** ac-php-core
|
|
This is a non server solution working entirely from an elisp package.
|
|
This requires no installation of external services but also delivers
|
|
the least amount of IDE like integrations with spacemacs.
|
|
|
|
To activate it just don't set the variable =php-backend= in your dotfile.
|
|
Remember that additional setup instructions are necessary on a per
|
|
project basis which you can find below.
|
|
|
|
**** Setup
|
|
Because of the way that the ac-php-core package works, there are a couple of simple
|
|
initialization tasks which must occur to get the completion working as it should.
|
|
On any new project make sure to perform the following initialization tasks:
|
|
1. Run the following
|
|
|
|
#+BEGIN_SRC shell
|
|
cd /root/of/project
|
|
touch .ac-php-conf.json
|
|
#+END_SRC
|
|
|
|
2. Inside of spacemacs run: = ac-php-remake-tags =
|
|
|
|
The =.ac-php-conf.json= file is required to enable auto-completion. When you run
|
|
=ac-php-remake-tags= and your =.ac-php-conf.json= file is empty the default configuration
|
|
will be used and inserted in the file.
|
|
|
|
If your project contains the following files at the root folder:
|
|
1. =.projectile=
|
|
2. =vendor/autoload.php=
|
|
|
|
the necessary configuration file (=.ac-php-conf.json=) will be created automatically
|
|
if it does not exist.
