Drop orphaned vim syntax files (#12502) 
I didn’t even know alp existed and this is definitely not the right
repo for Scala vim syntax defs. I’ve kept the daml def for now at
least since it’s at least in the right repo even if unmaintained.

Also seems very unfair towards emacs users to only have vim files.

Dev-env

This folder contains the development dependencies of this project.

Development

Structure

  • dev-env/lib/dade-common is the script meant to be included into all wrappers for dev-env provided tools and other dev-env specific tools (e.g. dade-info)
  • dev-env/lib/dade-dump-profile is a script which outputs - in porcelain mode - all environmental variables necessary for dev-env to function in a given shell.

Debugging

Run your comment with DADE_DEBUG=1 as prefix, e.g.:

DADE_DEBUG=1 jq

Environmental variables

Dev-env uses a common set of variables across it, here are they listed to be documented in future.

Public interface:

These variables are either used for dev-env initialization or are exported by dev-env for external tools to consume.

  • DADE_REPO_ROOT - root of a working directory where dev-env currently is executing; mutable content; input and output.
  • DADE_VAR_DIR - points to a directory which is meant for storing persistent and mutable data; mutable content; if not set, can be derived from DADE_DEVENV_DIR; input and output.
  • DADE_DEVENV_DIR - directory named dev-env under $DADE_BASE_ROOT, assume to be immutable (not yet the case); has to be set before dade-dump-profile is executed; input and output.
  • DADE_DESIRED_NIX_VERSION - user can provide this variable in their profile to silence the warning (in future, disable automatic installation of) the supported Nix version.

Private:

These variables are set in some of the dev-env tools and scripts and are not guaranteed to be always present in the dev-env environment (e.g. not guaranteed to be set by dade-common).

  • DADE_BASE_ROOT - root of the dev-env package; the directory which contains dev-env and nix directories, assume its immutable.
  • DADE_BUILD_RESULT - after a dev-env provided tool is built this variable is exported to point to a nix store where the tool was built.
  • DADE_DEBUG - sets -x in shell environemnt where dev-env scripts are executed.
  • DADE_CURRENT_SCRIPT_DIR - current directory of the currently running/sourced script, corresponds to $BASH_SOURCE[0], assume its immutable.
  • DADE_CURRENT_COMMAND - the name of the current command executed by dade
  • DADE_GC_ROOTS - points to a directory named gc-roots under DADE_VAR_DIR which contains Nix garbage collection roots and hashes for each dev-env provided tool individually; always mutable.
  • DADE_LIB_DIR - points to a directory lib under DADE_DEVENV_DIR which contains libraries for dev-env usage, assume its immutable.
  • DADE_NIXPKGS - points to a GC root which is a symlink to a Nixpkgs snapshot used by dev-env, used only in dade-dump-profile.
