---
--- An LSP server implementation for Pascal variants that are supported by Free Pascal, including Object Pascal. It uses CodeTools from Lazarus as backend.
---
--- First set `cmd` to the Pascal lsp binary.
---
--- Customization options are passed to pasls as environment variables for example in your `.bashrc`:
--- ```bash
--- export FPCDIR='/usr/lib/fpc/src'      # FPC source directory (This is the only required option for the server to work).
--- export PP='/usr/lib/fpc/3.2.2/ppcx64' # Path to the Free Pascal compiler executable.
--- export LAZARUSDIR='/usr/lib/lazarus'  # Path to the Lazarus sources.
--- export FPCTARGET=''                   # Target operating system for cross compiling.
--- export FPCTARGETCPU='x86_64'          # Target CPU for cross compiling.
--- ```
