This allows to reduce the horizontal size of the gutter; more efficient
management of folding since we already need to parse each line for the
linter; and eventually this will also allows to detect unbalanced
!#if-!#endif directives and report such cases as errors.
Additionally, keep incrementally improving error reporting details
in the linter.
This commits add the ability to open html/css/script
resources from the logger, as a formatted and syntax-
highligthed document.
The goal is to make it easier for filter list authors to
investigate filter-related issues.
`uDom` is old and crusty and `dom` is meant as replacement. The
goal of `dom` is to be simpler and mainly just convenience
methods for handling the DOM with vanilla JS -- this is not a
framework.
Additionally, removed keyboard shortcuts pane which was useful
only on very old versions of Firefox.
Too many changes to list here, essentially there is now a
user interface setting to enable/disable dark theme, and
I've rearranged a bit the Settings pane as a result and
also altered other visuals in various places.
There are places which I know have not been thoroughly
tested (i.e. logger inspector).
Will fine-tune as per feedback.
Issues with the classic popup panel will not be addressed,
and if feedback is that it has become unusuable, it will be
outright removed.

The changes are enough to fulfill the related issue.
A new platform has been added in order to allow for building
a NodeJS package. From the root of the project:
./tools/make-nodejs
This will create new uBlock0.nodejs directory in the
./dist/build directory, which is a valid NodeJS package.
From the root of the package, you can try:
node test
This will instantiate a static network filtering engine,
populated by easylist and easyprivacy, which can be used
to match network requests by filling the appropriate
filtering context object.
The test.js file contains code which is typical example
of usage of the package.
Limitations: the NodeJS package can't execute the WASM
versions of the code since the WASM module requires the
use of fetch(), which is not available in NodeJS.
This is a first pass at modularizing the codebase, and
while at it a number of opportunistic small rewrites
have also been made.
This commit requires the minimum supported version for
Chromium and Firefox be raised to 61 and 60 respectively.
Regex-based static network filters are those most likely to
cause performance degradation, and as such the best guard
against undue performance degradation caused by regex-based
filters is the ability to extract valid and good tokens
from regex patterns.
This commit introduces a complete regex parser so that the
static network filtering engine can now safely extract
tokens regardless of the complexity of the regex pattern.
The regex parser is a library imported from:
https://github.com/foo123/RegexAnalyzer
The syntax highlighter adds an underline to regex-based
filters as a visual aid to filter authors so as to avoid
mistakenly creating regex-based filters. This commit
further colors the underline as a warning when a regex-based
filter is found to be untokenizable.
Filter list authors are invited to spot these untokenizable
regex-based filters in their lists to verify that no
mistake were made for those filters, causing them to be
untokenizabke. For example, what appears to be a mistake:
/^https?:\/\/.*\/sw.js?.[a-zA-Z0-9%]{50,}/
Though the mistake is minor, the regex-based filter above
is untokenizable as a result, and become tokenizable when
the `.` is properly escaped:
/^https?:\/\/.*\/sw\.js?.[a-zA-Z0-9%]{50,}/
Filter list authors can use this search expression in the
asset viewer to find instances of regex-based filters:
/^(@@)?\/[^\n]+\/(\$|$)/

Changes:
From now on, uBO will allow click-to-subscribe on only
a few select domains, currently:
- https://filterlists.com/
- https://github.com/
- https://github.io/
More domains can be added if and only the demonstration
is made that more than a marginal number of filter lists
can be subscribed from those domains.
The browser alert box is no longer used to confirm
subscription to a filter list. Instead, the asset
viewer has been expanded to serve that purpose. This
way, users can peruse at the content of a filter list
before subscribing to it.
Before this commit, CodeMirror's add-on for search occurrences
was limited to find at most 1000 first occurrences, because of
performance considerations.
This commit removes this low limit by having the search
occurrences done in a dedicated worker. The limit is now
time-based, and highly unlikely to ever be hit under normal
condition.
With this change, all search occurrences are gathered,
and as a result:
- All occurrences are reported in the scrollbar instead of
just the 1,000 first
- The total count of all occurrences is now reported, instead
of capping at "1000+".
- The current occurrence rank at the cursor or selection
position is now reported -- this was not possible to report
this before.
The number of occurrences is line-based, it's not useful to
report finer-grained occurences in uBO.

CodeMirror's code folding reference:
- https://codemirror.net/doc/manual.html#addon_foldcode
This commit adds support for code-folding to the filter
list editor/viewer.
The following blocks of code are foldable by clicking the
corresponding marker in the gutter:
- !#if/#endif blocks
- !#include blocks
Addtionally, the following changes:
- The `!#include` line is now preserved when importing a
sublist
- The `!#if` directives will be syntax-colored according
to whether they evaluate to true or false on the current
platform
- Double-clicking on a foldable line in the gutter will
select the content of the foldable block
- Minor visual improvement to matching brackets
Rename `l` property to `len`, to avoid ambiguity as
`l` could mean _left_ or _length_. Typically `l` is
to be used for _left_ (whereas `r` is to be used for
_right_).
Additionally, add CodeMirror's bracket-matching and
bracket auto-closing to _My filters_ pane and and
bracket-matching to asset viewer page.
A new standalone static filtering parser is introduced,
vAPI.StaticFilteringParser. It's purpose is to parse
line of text into representation suitable for
compiling filters. It can additionally serves for
syntax highlighting purpose.
As a side effect, this solves:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1038
This is a first draft, there are more work left to do
to further perfect the implementation and extend its
capabilities, especially those useful to assist filter
authors.
For the time being, this commits break line-continuation
syntax highlighting -- which was already flaky prior to
this commit anyway.
... for the sake of portability.
When including vapi-common.js in an HTML file, then the body element there
will have a "dir" attribute filled with the current locale's direction
(ltr or rtl).
The following languages are considered right-to-left: ar, he, fa, ps, ur.
Everything else is left-to-right.
After the "dir" attribute is set, we can decide in CSS which elements
should have different styling for rtl languages (e.g., body[dir=rtl] #id).
