* chore(tests): Remove circular import loading issue kludge
Prior to PR #6818, circular imports resulted in the debug module
loader (in closure/goog/base.js) failing to record the
goog.module ID of most modules that were
involved in the cycle, and in particular of the Blockly.Xml
module. This had secondary fallout that resulted
in library blocks modules being loaded in the wrong order.
A kludge was introduced in PR #6703 that worked around this
problem by making sure that window.Blockly was set, allowing
the modules loaded out-of-order to still work.
Now that we have removed all remaining circular dependencies
there is no need for the kludge, since all module IDs are
properly recorded and modules are loaded in the correct order.
* chore(build): Remove exclude for non-existent core/blockly.js
There was a transitional period where we had both
core/blockly.ts and core/blockly.js, and wished to exclude
the latter from tsc's input, but the latter file was deleted
(and inadvertently restored, then re-deleted) some time ago.
This change had already been made (by PR #6475 amongst other) to
most of the tests, but there were a couple of stragglers that
still mentioned messages.js.
Fixes#6824.
Previously we had code that would, in uncompiled mode, make sure
that javascriptGenerator etc. were set to the corresponding module
exports object (by fetching it with goog.module.get), but in
compressed mode we made no effort to set (e.g.) javascriptGenerator
to Blockly.JavaScript, which is where that export actually appears
in the namespace tree when loading the chunk via a <script> tag.
This commit introduces two new configuration options to bootstrap.js
(preconfigured with defaults that should work in most cases) mapping
global variable names to their corresponding module identifiers, and
modifies the code in bootstrap_helper.js to set global variables
appropriately in both uncompressed and compressed modes.
* fix(build): Minor corrections to build_tasks.js
- Use TSC_OUTPUT_DIR to find goog/goog.js when suppressing warnings.
- Remove unnecessary trailing semicolons.
* refactor(blocks): Remove declareLegacyNamespace
Remove the call to goog.module.declareLegacyNamespace from
Blockly.libraryBlocks. This entails:
- Changes to the UMD wrapper to be able to find the exports object.
- Changes to tests/bootstrap_helper.js to save the exports object
in the libraryBlocks global variable.
- As a precaution, renaming the tests/compile/test_blocks.js module
so that goog.provide does not touch Blockly or
Blockly.libraryBlocks, which may not exist / be writable.
* feat(build): Add support named exports from chunks
We need to convert the generators to named exports. For backwards
compatibility we still want e.g. Blockly.JavaScript to point at
the generator object when the chunk is loaded using a script tag.
Modify chunkWrapper to honour a .reexportOnly property in the
chunks table and generate suitable additional code in the UMD
wrapper.
* refactor(generators): Migrate JavaScript generator to named export
- Export the JavaScript generator object as javascriptGenerator
from the Blockly.JavaScript module(generators/javascript.js).
- Modify the Blockly.JavaScript.all module
(generators/javascript/all.js) to reexport the exports from
Blockly.JavaScript.
- Update chunk configuration so the generator object remains
available as Blockly.JavaScript when loading
javascript_compressed.js via a <script> tag.
(N.B. it is otherwise necessary to destructure the require
/ import.)
- Modify bootstrap_helper.js to store that export as
window.javascriptGenerator for use in test code.
- Modify test code to use javascriptGenerator instead of
Blockly.JavaScript.
- Modify .eslintrc.json so that javascriptGenerator is allowed
as a global in test/. (Also restrict use of Blockly global
to test/.)
N.B. that demo code in demos/code/code.js uses <script> tag
loading and so will continue to access Blockly.JavaScript.
* refactor(generators): Migrate Lua generator to named export
* refactor(generators): Migrate PHP generator to named export
* refactor(generators): Migrate Python generator to named export
* refactor(generators): Remove declareLegacyNamespace calls
Remove the goog.module.declareLegacyNamespace calls from the
generators.
This turns out to have the unexpected side-effect of causing the
compiler to rename the core/blockly.js exports object from
$.Blockly to just Blockly in blockly_compressed.js - presumably
because it no longer needs to be accessed in any subsequent chunk
because they no longer add properties to it. This requires
some changes (mainly simplification) to the chunkWrapper function
in build_tasks.js.
* refactor(core): Remove declareLegacyNamespace from blockly.js
So easy to do _now_: just need to:
- Make sure the UMD wrapper for the first chunk knows where the
exports object is.
- Use that same value to set the Blockly.VERSION @define.
- Have bootstrap_helper.js set window.Blockly to the exports
object.
- Fix tests/compile/test_blocks.js to not assume a Blockly
global variable, by converting it to a goog.module so we
can use a named require.
* refactor(tests): Move and rename prepare.js, blockly.mjs
Since prepare.js and blockly.mjs are going to be needed for running
all tests in uncompiled mode (not just the playgrounds), move them
tests/. Further, rename prepare.js to bootstrap.js to better reflect
its purpose.
* feat(tests): Introduce BLOCKLY_BOOTSTRAP_OPTIONS
Provide a mechanism for web pages that use bootstrap.js to control
what is loaded and how.
* fix(tests): Use the blockly repository path for all script src= URLs
Previously the (non-advanced) playground was only correctly loadging
on localhost because you can put an arbitrary number of "../"s in front
of a relative URL and it just takes you to the root directory.
* fix(tests): Don't use template literals in bootstrap.js
This is necessary (but not necessarily sufficient) to be able to
load the file in IE 11.
* fix(tests): Throw error if attempting to bootstrap in node.js
* feat(tests): Make bootstrap.js more configurable.
* Terminology change: use "compressed" and "uncompressed" to describe
what Closure Compiler calls "compiled" and "uncompiled", to reduce
confusion with the compilation that will be done by tsc.
* Get the list of modules to bootstrap (in compressed mode), or
scripts to load (in compressed mode) from BLOCKLY_BOOTSTRAP_OPTIONS,
to allow calling scripts to to specify exactly what to load.
* feat(tests): Use a proper quote function
We need to generate string literals. Best to use a quote function
instead of concatenating on quote marks withou escaping. Copy a
well-tested one from Code City.
* feat(tests): Support an additionalScripts option
This is a list of scripts to load (in order) once the required modules
have been bootstrapped.
We do this using goog.addDependency to make the first script depend
on the required modules, then each subsequent script depend on the
previous one, and then finally goog.bootstrapping the last such script.
* refactor(tests): Remove special handling of msg/messages.js
* refactor(tests): Use additionalScripts for all script loading
Use additionalScripts option for all script loading in
playground.html and advanced_playground.html.
* refactor(tests): Use bootstrap instead of uncompressed in Mocha tests
Use tests/bootstrap.js instead of blockly_uncompressed.js to load
blockly in uncompressed mode in the Mocha tests.
This entails adding a new item, despFiles, to BLOCKLY_BOOTSTRAP_OPTIONS,
to allow tests/deps.mocha.js to be loaded at the appropriate point.
Mention of blockly_uncompressed.js is removed from
tests/mocah/.mocharc.js; it's not clear to me what effect the "file:"
directive in this file might have previously had and I was not able to
find documentation for it on mochajs.org, but in any case removing it
appears to have had no ill effect.
* refactor(tests): Use bootstrap instead of uncompressed in generator tests
This entails adding an additional check in bootstrap so as to load
uncompressed when loading from a file: URL, since these are not
localhost URLs - though in fact the generator tests run equally well
in compressed mode, albeit against (for now) the previously-check-in
build products rather than the live code.
* refactor(test): Use bootstrap.js in multi_playground.html
This removes the last use of load_all.js, so remove it.
* chore(tests): Delete blockly_uncompressed.js
Its function has now been entirely subsumed by tests/bootstrap.js,
so remove it and update any remaining mentions of it.
Also fix formatting and positions of some comments in playground.html.
* fix(tests): Rewrite bootstrap sequencing code
An earlier commit modified the generated <script> to use
goog.addDependency to trick the debug module loader into loading
.additionalScripts (via goog.bootstrap), but it turns out there is
a small problem: scripts like msg/messages.js have undeclared
dependencies on the Blockly module, and without a call to
goog.require('Blockly') in them they can end up being run before
the Blockly module is fully loaded.
(This problem only occurs when there are ES Modules, rather than
merely goog.modules, in the mix.)
Fix this by adding a script, bootstrap_helper.js, to be loaded
options.requires and any options.additionalScripts that makes an
explicit call to goog.require for each of option.requires.
Also refactor the code so that instead of generating a loop which
calls goog.addDependency, we generate the addDependency calls
directly. This makes debugging a bit easer as we can use the browser's
dev tools to inspect the generated calls in the DOM tree.
* fix(tests): Prevent spurious transpilation warnings
For some reason when the debug module loader encounters ES modules
it starts to complain about being unable to transpile some ES202x
features in other (non-ESM) modules, even though it doesn't normally
try to transpile those.
Since uncompressed-mode testing is almost exclusively on modern
browsers we don't care about transpiling these features, so suppress
the warnings instead.
* refactor(tests): Rename blockly.mjs to bootstrap_done.mjs; simplify
Since blockly.mjs is no longer returning just the exports object
from core/blockly.js (see PR #5995), it might be better named after
its actual purpose: to wait for bootstrapping to be done.
Remove all the code that was used to pass the blockly.js exports
object along from the bootstrap callback to the blockly.mjs export,
since there's no reason to go to a lot of trouble to set a local
variable named Blockly to the same value as a global variable named
Blockly.
(Something like this may be needed again in future, but certainly in
a different form.)
* chore(tests): Use freshly-build files in compressed mode.
Use the freshly-built build/*_compresssed.js files when bootstrapping
in compressed mode, rather than using the checked-in files in the
repository root.
This helps ensure that compressed and uncompressed mode will be
testing (as closely as possible) the same code.
* chore(tests): Rename BlocklyLoader to blocklyLoader; record compressed
- Rename the BlocklyLoader global to blocklyLoader (since it is not
a class constructor).
- Create it regardless of whether we are bootstrapping in
uncompressed or loading compressed via <script> tags.
- Record which we are doing as .compressed, and use this property
to choose playground background colour.
* chore(tests): Resolve comments for PR #6214
Mostly documentation changes, but notably renaming blocklyLoader to
bootstrapInfo.
* Revert "chore(tests): Use freshly-build files in compressed mode."
This reverts commit de8d356838.
