This package provides editor support for PureScript projects in Atom, based on a Language Server which uses the
purs compiler IDE server functionality,
with UI provided via the atom-ide framework.
This package provides:
Package should trigger on opening a
.purs file or running any PureScript/PSCI command from the menu bar or command palette.
For best results (and default settings) install dependencies:
purs(compiler) 0.8.5 or >= 0.9.1 (includes
ide serversubcommand as standard)
pulp>= 8.0.0 (appropriate for your
pscversion). >=10.0.0 recommended to use default build command
Required atom packages - these should be auto-installed by starting the package, eg by running any PureScript command.
For use with older versions of pulp, or for alternative build tools and configuration tips, see below. In brief the build command is configurable, but should output JSON errors.
This package runs a langauge server process, which itself starts a compiler server process,
purs ide server
psc-ide-server), to provide type information, completions,etc. This package will automatically start
the IDE server in your project directory and kill it when closing, if for some reason
you want a longer running server process you should be able to start that before
For all functions provided by
purs ide server you will need to build your project first! In particular a full build,
fast-build on save, is required first time or after upgrading
purs, afterwards saving individual files
will update tooltips etc.
Provided from the IDE server. Make sure your project is built first. Only for top level definitions.
Completions will be sourced from all available modules by default; this is configurable to just those imported in the current file, in which case explicitly (re-)triggering the completion will expand to show all modules.
Imports will be inserted automatically for completions! Again this is configurable.
Hovering over an identifier will show a tooltip with its type (only for top level definitions):
This is really stupid, and only cares that you hover over a word regardless of context, you will get some false positives.
Hyperclick goto-definition functionality is supported. This is available with
0.9.2 and above, and like tooltips/autocomplete works on identifiers bound at the top level.
This is available as command/ctrl+click or cmd+alt/opt+enter by default, see atom-ide-ui config.
In case source positions are not up to date, they may not be updated on rebuild, try rebuilding or restarting psc-ide server.
Command available from the command palette:
Basic PSCI REPL integration (runs
pulp psci). Comprises a read-only pane which displays
PSCI output, and an input field to send expressions to the REPL (just hitting enter). Input
can be sent from the current buffer by line or selection.
Command from the command palette:
Build support is provided via
pulp build by default, configurable to any command which
will output psc errors. This can be configured to run on save, alternatively there
is a 'PureScript Build' command.
As well as this there is
fast rebuild via the IDE server on save (by default), this will
build an individual file. The recommended approach is to run a full build initially and
after any dependency upgrades, compiler updates, etc. or when producing build artifacts, and
otherwise quick build for continuous error feedback.
The default build command is
pulp build -- --json-errors
pulp.cmd is called instead). Note This default requires pulp 0.10 as command syntax changed to require
This is configurable: the command should be on your PATH (or could be an explicit absolute path) with arguments, such that it will
output JSON errors as per
psc, on stderr. This is not interpreted via shell, simply
pulled apart as a list of string separated arguments.
pulp --psc-package build -- --json-errors
psc bower_components/purescript-*/src/**/*.purs src/**/*.purs --json-errors
gulp- again need to ensure this outputs JSON errors, you probably want a specific task for this.
Pulp passing through
pulp build -- --stash --json-errors
This will pass through
psc errors as JSON but also integrate to any external
e.g. if you're running
psa on a terminal somewhere. Right now the stashed warnings are not exposed in the JSON.
Ensure tests are compiled in the build:
pulp build --include test -- --json-errors
Via npm run script:
npm run -s build. Or if the run script does not output json errors you might be able to pass
an extra flag:
npm run -s build -- --json-errors - more information on this issue.
Since atom unfortunately does not support per-project configuration, the npm run script approach may be particularly useful where you have different projects that build differently. Alternatively you can look into the project-manager package.
You may be able to get away without thinking about all this if your project specific setup is only required for a
(e.g. browserify step) and not just for the basic compilation stage.
Error suggestions may be triggered from some underlined compiler warnings. There is no additional visual indication. A context menu can be triggered by 'alt-enter' (PureScript: Show Quick Fixes) when the cursor is on an eligible warning. Currently fixable warnings:
_- fill in type signature. Notes as above. (
^O c) - use psc-ide to add a clause to the current top-level function (from cursor on its type definition).
^O s) - with cursor on an function argument identifier, add clauses to the definition to case-split on that argument.
Currently the type of the arguments must be provided by the user.
After cloning, install dependencies
Bundle for Atom:
npm run -s bundle
You can use the regular
pulp build as part of your tooling or to see compile errors, but bundling is required for the plugin to be usable by Atom and will build the project as part of the task.
To use your local development version, you will first need to uninstall any current version you have installed. Then from within the atom-ide-purescript directory run
apm link. This will create a symlink from the Atom plugins directory to your development directory.
Various configuration options on completion
Completions are grouped to avoid listing each re-export. As often the re-exported version is the desired import (e.g. anything in Prelude and common pattern of re-exporting at the top level module), the follwoing strategies are used for picking the re-export to choose 1. Existing imports 2. User configuration of preferred modules (ordered list) 3. Re-export from a prefix named module (e.g. Foo.Bar.Baz reexported from Foo.Bar) shortest first 4. Original module (if none of the previous rules apply, there are no re-exports, or either grouping is disabled or compiler version does not support it)
purs executable is now supported. For the initial transition period this is still optional, configured via the package settings, the default is still to use the old
psc-ide-server. In time this default will be changed then the legacy support will be removed.
Note that the support for the
npm bin folder lets you run with a mix of old and new-versioned projects.
Update to Linter 2.0 API
This means fixes are now applied via Linter instead of a homebrew solution, via https://github.com/steelbrain/intentions UI. The existing ide-purescript:show-quick-fixes command now redirects to
intentions:show, and the existing binding should work - but you should update to using intentions directly. You can apply all suggestions via
