* Removed the distinction in the tokenizer between installed
extensions and natively supported extension tags (<ref> and
<references> for ex.). They all tokenize and get processed
identically and get handled by different paths in the extension
handler.
* Template and TemplateArg tokens now carry tpl. transclusion
source alongwith them since tsr information will not be
accurate when they show up in extension contexts that in turn
showed up in template context that were expanded by the php
preprocessor.
Ex: {{echo|<ref>{{echo|foo}}</ref>}}
The tsr for the ref-tag will correspond to the
template-source of the echo-template, NOT the original top-level
page. So, env.page.src.substring(..) will return incorrect
source for the innermost {{echo|foo}}. This fix of carrying

* Natively implemented extension tags (<ref> and <references>)
are hardcoded in env.conf.parsoid. At some point, it would

extensions.

* The handler now processes ref-tokens, parses content all

attribute of a meta-token that serves as a placeholder for
where the ref-token occured.
* References are handled as a DOM post-pass where these meta
placeholder tokens are collected, content extracted from
the attribute and spit out at the site of a references tag.

* Removed a FIXME in DOMUtils.buildTokensFromDOM by reusing code
in the tokenizer that converts "\n" in text to NlTks.
* Cleanup of Util.shiftTokenTSR.
* ext.util.TokenCollection is now no longer used by anything.
Added a FIXME and left around in case we are able to improve
tokenizing and handling of *include* tags that can eliminate the
need for the messy TokenAndAttrCollector.
Test results
------------
* No change in parser tests results.
* Tested with a few different files.
- en:BO page seems to be parsed about 10% faster than before
(needs verification).
- Referencs on the en:BO page seem to be more accurate than
before.

Extension handling rewrite + cite extension refactoring.
Tokenization
------------
* Fixed tokenizer to correctly parse extension tags in different
contexts: with start and end tags, in self-closing tag mode,
and to correctly handle scenarios when the exension end-tag is
followed by a '#' (the special char used to skip over extension
content).
* Removed the distinction in the tokenizer between installed
extensions and natively supported extension tags (<ref> and
<references> for ex.). They all tokenize and get processed
identically and get handled by different paths in the extension
handler.
* Template and TemplateArg tokens now carry tpl. transclusion
source alongwith them since tsr information will not be
accurate when they show up in extension contexts that in turn
showed up in template context that were expanded by the php
preprocessor.
Ex: {{echo|<ref>{{echo|foo}}</ref>}}
The tsr for the ref-tag will correspond to the
template-source of the echo-template, NOT the original top-level
page. So, env.page.src.substring(..) will return incorrect
source for the innermost {{echo|foo}}. This fix of carrying
along tpl transclusion source in the token itself eliminates
this problem.
Knowledge of native extensions
------------------------------
* Natively implemented extension tags (<ref> and <references>)
are hardcoded in env.conf.parsoid. At some point, it would
be good to have a registration mechanism for parsoid-native
extensions.
Extension handling
------------------
* Extracted extension handling out of the template handler into
its own handler class. Right now, this class inherits from the
template handler in order to be able to reuse a lot of the
expansion and encapsulation functionality currently in the
Template Handler.
* This handler now handles extensions that are:
(a) natively implemented and registered with Parsoid.
(b) implemented as a PHP extension and expanded by relying on
the PHP preprocessor.
For (a), it uses information from env.conf.parsoid to find
ext-handlers for natively implemented ext-tags. However, this
can be cleaned up at some point by making available a registration
mechanism.
Cite/Ref/References
-------------------
* Reworked the cite handler to split up ref-token processing
and references token processing.
* The handler now processes ref-tokens, parses content all
the way to html output and encapsulates the html in an
attribute of a meta-token that serves as a placeholder for
where the ref-token occured.
* References are handled as a DOM post-pass where these meta
placeholder tokens are collected, content extracted from
the attribute and spit out at the site of a references tag.
The DOM walking is in DOMPostProcessor.js, but the actual
processing is part of the Cite.js to keep all cite extension
handling code in one place.
Parser pipeline
---------------
* Restructured parser pipeline recipes based on changes to Cite,
TemplateHandler, and ExtensionHandler.
* Added a couple functions to the parser pipeline:
1. resetState to reset state before starting a new top-level parse
when pipelines are reused across top-level parses (ex: parser
tests)
2. setSourceOffsets to set start/end offsets of the source being
handled by the pipeline. This is required to correctly set tsr
values when extension content (which is a substring of original
top-level text) is parsed in its own pipeline.
Other fixes
-----------
* Removed env parameter from the Params object since it was not
being used and seemed like unnecessary state propagation.
* Removed a FIXME in DOMUtils.buildTokensFromDOM by reusing code
in the tokenizer that converts "\n" in text to NlTks.
* Cleanup of Util.shiftTokenTSR.
* ext.util.TokenCollection is now no longer used by anything.
Added a FIXME and left around in case we are able to improve
tokenizing and handling of *include* tags that can eliminate the
need for the messy TokenAndAttrCollector.
Test results
------------
* No change in parser tests results.
* Tested with a few different files.
- en:BO page seems to be parsed about 10% faster than before
(needs verification).
- Referencs on the en:BO page seem to be more accurate than
before.

Extension handling rewrite + cite extension refactoring.
Tokenization
------------
* Fixed tokenizer to correctly parse extension tags in different
contexts: with start and end tags, in self-closing tag mode,
and to correctly handle scenarios when the exension end-tag is
followed by a '#' (the special char used to skip over extension
content).
* Removed the distinction in the tokenizer between installed
extensions and natively supported extension tags (<ref> and
<references> for ex.). They all tokenize and get processed
identically and get handled by different paths in the extension
handler.
* Template and TemplateArg tokens now carry tpl. transclusion
source alongwith them since tsr information will not be
accurate when they show up in extension contexts that in turn
showed up in template context that were expanded by the php
preprocessor.
Ex: {{echo|<ref>{{echo|foo}}</ref>}}
The tsr for the ref-tag will correspond to the
template-source of the echo-template, NOT the original top-level
page. So, env.page.src.substring(..) will return incorrect
source for the innermost {{echo|foo}}. This fix of carrying
along tpl transclusion source in the token itself eliminates
this problem.
Knowledge of native extensions
------------------------------
* Natively implemented extension tags (<ref> and <references>)
are hardcoded in env.conf.parsoid. At some point, it would
be good to have a registration mechanism for parsoid-native
extensions.
Extension handling
------------------
* Extracted extension handling out of the template handler into
its own handler class. Right now, this class inherits from the
template handler in order to be able to reuse a lot of the
expansion and encapsulation functionality currently in the
Template Handler.
* This handler now handles extensions that are:
(a) natively implemented and registered with Parsoid.
(b) implemented as a PHP extension and expanded by relying on
the PHP preprocessor.
For (a), it uses information from env.conf.parsoid to find
ext-handlers for natively implemented ext-tags. However, this
can be cleaned up at some point by making available a registration
mechanism.
Cite/Ref/References
-------------------
* Reworked the cite handler to split up ref-token processing
and references token processing.
* The handler now processes ref-tokens, parses content all
the way to html output and encapsulates the html in an
attribute of a meta-token that serves as a placeholder for
where the ref-token occured.
* References are handled as a DOM post-pass where these meta
placeholder tokens are collected, content extracted from
the attribute and spit out at the site of a references tag.
The DOM walking is in DOMPostProcessor.js, but the actual
processing is part of the Cite.js to keep all cite extension
handling code in one place.
Parser pipeline
---------------
* Restructured parser pipeline recipes based on changes to Cite,
TemplateHandler, and ExtensionHandler.
* Added a couple functions to the parser pipeline:
1. resetState to reset state before starting a new top-level parse
when pipelines are reused across top-level parses (ex: parser
tests)
2. setSourceOffsets to set start/end offsets of the source being
handled by the pipeline. This is required to correctly set tsr
values when extension content (which is a substring of original
top-level text) is parsed in its own pipeline.
Other fixes
-----------
* Removed env parameter from the Params object since it was not
being used and seemed like unnecessary state propagation.
* Removed a FIXME in DOMUtils.buildTokensFromDOM by reusing code
in the tokenizer that converts "\n" in text to NlTks.
* Cleanup of Util.shiftTokenTSR.
* ext.util.TokenCollection is now no longer used by anything.
Added a FIXME and left around in case we are able to improve
tokenizing and handling of *include* tags that can eliminate the
need for the messy TokenAndAttrCollector.
Test results
------------
* No change in parser tests results.
* Tested with a few different files.
- en:BO page seems to be parsed about 10% faster than before
(needs verification).
- Referencs on the en:BO page seem to be more accurate than
before.

handled by the pipeline. This is required to correctly set tsr
values when extension content (which is a substring of original
top-level text) is parsed in its own pipeline.
Other fixes
-----------
* Removed env parameter from the Params object since it was not
being used and seemed like unnecessary state propagation.
* Removed a FIXME in DOMUtils.buildTokensFromDOM by reusing code
in the tokenizer that converts "\n" in text to NlTks.
* Cleanup of Util.shiftTokenTSR.
* ext.util.TokenCollection is now no longer used by anything.
Added a FIXME and left around in case we are able to improve
tokenizing and handling of *include* tags that can eliminate the
need for the messy TokenAndAttrCollector.
Test results
------------
* No change in parser tests results.
* Tested with a few different files.
- en:BO page seems to be parsed about 10% faster than before
(needs verification).
- Referencs on the en:BO page seem to be more accurate than
before.

Extension handling rewrite + cite extension refactoring.
Tokenization
------------
* Fixed tokenizer to correctly parse extension tags in different
contexts: with start and end tags, in self-closing tag mode,
and to correctly handle scenarios when the exension end-tag is
followed by a '#' (the special char used to skip over extension
content).
* Removed the distinction in the tokenizer between installed
extensions and natively supported extension tags (<ref> and
<references> for ex.). They all tokenize and get processed
identically and get handled by different paths in the extension
handler.
* Template and TemplateArg tokens now carry tpl. transclusion
source alongwith them since tsr information will not be
accurate when they show up in extension contexts that in turn
showed up in template context that were expanded by the php
preprocessor.
Ex: {{echo|<ref>{{echo|foo}}</ref>}}
The tsr for the ref-tag will correspond to the
template-source of the echo-template, NOT the original top-level
page. So, env.page.src.substring(..) will return incorrect
source for the innermost {{echo|foo}}. This fix of carrying
along tpl transclusion source in the token itself eliminates
this problem.
Knowledge of native extensions
------------------------------
* Natively implemented extension tags (<ref> and <references>)
are hardcoded in env.conf.parsoid. At some point, it would
be good to have a registration mechanism for parsoid-native
extensions.
Extension handling
------------------
* Extracted extension handling out of the template handler into
its own handler class. Right now, this class inherits from the
template handler in order to be able to reuse a lot of the
expansion and encapsulation functionality currently in the
Template Handler.
* This handler now handles extensions that are:
(a) natively implemented and registered with Parsoid.
(b) implemented as a PHP extension and expanded by relying on
the PHP preprocessor.
For (a), it uses information from env.conf.parsoid to find
ext-handlers for natively implemented ext-tags. However, this
can be cleaned up at some point by making available a registration
mechanism.
Cite/Ref/References
-------------------
* Reworked the cite handler to split up ref-token processing
and references token processing.
* The handler now processes ref-tokens, parses content all
the way to html output and encapsulates the html in an
attribute of a meta-token that serves as a placeholder for
where the ref-token occured.
* References are handled as a DOM post-pass where these meta
placeholder tokens are collected, content extracted from
the attribute and spit out at the site of a references tag.
The DOM walking is in DOMPostProcessor.js, but the actual
processing is part of the Cite.js to keep all cite extension
handling code in one place.
Parser pipeline
---------------
* Restructured parser pipeline recipes based on changes to Cite,
TemplateHandler, and ExtensionHandler.
* Added a couple functions to the parser pipeline:
1. resetState to reset state before starting a new top-level parse
when pipelines are reused across top-level parses (ex: parser
tests)
2. setSourceOffsets to set start/end offsets of the source being
handled by the pipeline. This is required to correctly set tsr
values when extension content (which is a substring of original
top-level text) is parsed in its own pipeline.
Other fixes
