bazel's Issues

Bazelify should add the pub repositories to the WORKSPACE if needed

Something like:

load( "@io_bazel_rules_dart//dart/build_rules:pub.bzl", "pub_repositories", ) pub_repositories()

Create `dazel build command` which builds the dart_web_binary and unpacks the tar file into a top level folder (configurable?).

Blocked by dart-archive/rules_dart#74

Should we skip the `foo` entry in .packages for the foo package?

My silly_monkey package has this .packages file

# Generated by pub on 2016-10-12 18:31:00.470898.
path:file:///Users/kevmoo/.pub-cache/hosted/pub.dartlang.org/path-1.4.0/lib/
silly_monkey:lib/

Noticed we create this entry in packages.bzl – seems like this should just be a direct dependency thing – and not a local_repository ... thing

    native.new_local_repository(
        name = "silly_monkey",
        path = "/Users/kevmoo/temp/silly_monkey",
        build_file = ".bazelify/silly_monkey.BUILD",
    )

Make it easier to get reproducible BUILD and workspace setups

An option to point repositories to pub instead of the local cache could make it so that it's easy to bazelify init and then share the generated files.

We'll want to be careful in how this is presented and warn that thing might not be compatible across versions of rules_dart

Should split dart:html and dart:io entry points

Today all transitive dependencies attempt to compile all their sources with DDC. We need to separate things out so it only compiles the web-safe dependencies as a separate target.

This is particularly an issue for any package declaring a transformer.

We should configure the repository to only allow reviewed commits to get merged into master

Unlike the labels one I'm pretty confident I don't have permission for this one
https://help.github.com/articles/enabling-required-status-checks/

More than one entry point creates conflicting rules

I have 3 entry points in web/ and bazelify creates a rule for each. When I want to build or run I always get errors because of conflicting rules.

I removed the duplicate rules in BUILD but now I get conflicts for rules of dependency packages.

/home/myuser/.cache/myuser/_bazel_myuser/d7cc63dbd0d8e0618a44683ac56d1bee/external/ng_bootstrap/BUILD:89:1: dart_web_application rule 'main' in package '' conflicts with existing dart_web_application rule.

ng_bootstrap is a dependency and I don't care about it's entry points because its just the demo applications. Any hint how to work around? I'm just starting with bazel.

update app discovery logic to start from html files

treat each html file under web as an entry point, query it for a script[type="application/dart"] and use that as the entry point dart file.

Bazelify should manage BUILD file until the users changes it

We should use a hash or some technique to determine whether bazelify is the 'owner' of the BUILD file and keep it up to date as the package changes. Once the users makes their own change and invalidates it we can stop updating it with buildify.

Add option to prefix namespaces

See dart-archive/rules_dart#61 (comment)

Some package names might conflict if using this in a larger bazel workspace

Print out which targets are discovered – what rules are generated, how to use them

We found a web project at web/index.html generated a web target

Invoke it with bazel run XYZ

etc etc

Should support omitting `targets` section in build.yaml

Now that build.yaml is used for more than just targets, we should allow omitting targets and falling back on the default behavior when the file isn't present.

Need to document package: URI convension

There should be some advice in this package for how to structure the workspace (where to put packages, etc.) and a description of how the package: URI's are written and resolved.

Investigate sandbox errors when running dazel build test

Currently this is causing us to disable the sandbox for the DartPackagesDir and Dart2jsCompile actions.

Pub global activate does not add executable bazel

I can not run bazelify, because:

This happens on ubuntu 16.04.

Package names with leading underscore become invalid workspace names

A bazel workspace name must start with a letter but pub package names are allowed to start with an underscore. We should prefix package names for use as a remote repository name in bazel. Some options:

pkg_
dartlang_
pub_

Before I run bazelify serve I purged the ~/.pub-cache/hosted/pub.dartlang.org directory and the .pub directory and then run

pub upgrade
bazelify

(I had to change the BUILD file a bit because I didn't have an web/index.html but instead a web/dashboard_layout_demo.html which was not properly recognized everywhere.)

I don't know where this file comes from. It's not in the dart_style repo. Might have existed at the uploader of the dart_style package, therefore the dart_style repo might be the right place to file the issue but perhaps DDC shouldn't fail at such a file anyway:

Dart VM version: 1.21.0-edge.a850b4c977a5b177abe17864006657111d835840 (Mon Oct 31 18:04:44 2016) on "linux_x64"

Copied from original issue: dart-lang/sdk#27713

Should print and set exit code instead of throwing

users don't want to see stack traces :)

Unify printing of timing through `StepTimer`.

Today the build command does its own thing (which is nicer imo), but other things use StepTimer.

The main difference is that StepTimer prints all times at the end instead of incrementally as you go, where the custom logic in the build command prints the current time on the left whenever you log.

We should unify the logic and migrate build to the StepTimer.

Stop setting `exitCode` outside of the root app

We're just asking for confusion.

Better to throw a custom Error that we know how to handle at the root.

Should support customizing `srcs` on for builder targets

Most authors will likely leave this empty and use the target as the library that has builder factories - though it's also possible to define the factories in bin/ and use a relative import, in this case we'd need to support srcs.

We could also consider the case where all code generation is defined in 'bin/' and we need to support both srcs and deps in place of target

Update dazel.yaml to support exporting a `Builder` (package authors)

Blocked on dart-archive/rules_dart#73

Bazelify should auto-generate a WORKSPACE file if one does not exist

Tentative template:

# Dart SDK.
local_repository(
    name = "io_bazel_rules_dart",
    path = "{{PATH_TO_RULES_DART}}",
)
load(
    "@io_bazel_rules_dart//dart/build_rules:repositories.bzl",
    "dart_repositories",
)
dart_repositories()

# Pubspec converted to Bazel by Bazelify.
load("//:packages.bzl", "bazelify")
bazelify()

io_bazel_rules_dart can be replaced with git+SSH in #2

Add path to .packages file to the dev server rule

After dart-archive/rules_dart#47, the server will support passing a --package-spec option which it will use to resolve packages/ style paths. We will need to pass that arg as part of the dev_server rule though.

Segment travis builds into seperate projects

See

Gives us some parallelization and will make it easier to find breaks to one part of this project.

Can't analyze sources that were output in previous Builder when running subsequent Builder

We prime the BuildAssetUriResolver with the srcs files so they can be read synchronously. Later when we write new assets the resolver doesn't know about them.

We need some hook to add additional (synchronous) assets available for reading.

Add `bazelify run` command

I think this should work with a similar syntax to pub run, where you specify the target using $package:$executable. Only supporting things in bin is fine for now I think.

add CHANGELOG

Help folks .gitignore the right things

.bazelify
bazel-*

See kevmoo/bazel_dart_hax@ad90bd3

Bazelify should auto-generate a BUILD file with ...

A dart_library if we see a lib directory
A dart_vm_binary if we see a bin directory

add `bazelify run` to help invoke server, etc

use a sub-command

for web apps: run the watching server w/ the right args

for other apps ???

Only generate dart_vm_binary for executables

Help folks ignore bazel-* in .analysis_options
