If this is your first time building the HTML5 parser, you need to execute the
|
|
following commands (from this directory) to bootstrap the translation:
|
|
|
|
make sync # fetch remote source files and licenses
|
|
make translate # perform the Java-to-C++ translation from the remote
|
|
# sources
|
|
make named_characters # Generate tables for named character tokenization
|
|
|
|
If you make changes to the translator or the javaparser, you can rebuild by
|
|
retyping 'make' in this directory. If you make changes to the HTML5 Java
|
|
implementation, you can retranslate the Java sources from the htmlparser
|
|
repository by retyping 'make translate' in this directory.
|
|
|
|
The makefile supports the following targets:
|
|
|
|
sync_htmlparser:
|
|
Retrieves the HTML parser and Java to C++ translator sources from GitHub.
|
|
sync_javaparser:
|
|
Retrieves the javaparser sources from GitHub.
|
|
sync:
|
|
Runs both sync_javaparser and sync_htmlparser.
|
|
javaparser:
|
|
Builds the javaparser library retrieved earlier by sync_javaparser.
|
|
translator:
|
|
Runs the javaparser target and then builds the Java to C++ translator from
|
|
sources retrieved earlier by sync_htmlparser.
|
|
libs:
|
|
The default target. Alias for translator
|
|
translate:
|
|
Runs the translator target and then translates the HTML parser sources
|
|
retrieved by sync_htmlparser copying the Java sources to ../javasrc.
|
|
translate_from_snapshot:
|
|
Runs the translator target and then translates the HTML parser sources
|
|
stored in ../javasrc.
|
|
named_characters:
|
|
Generates data tables for named character tokenization.

## How to add an attribute
|
|
|
|
# starting from the root of a mozilla-central checkout
|
|
cd parser/html/java/
|
|
make sync
|
|
# now you have a clone of https://github.com/validator/htmlparser/tree/master in parser/html/java/htmlparser/
|
|
cd htmlparser/src/
|
|
$EDITOR nu/validator/htmlparser/impl/AttributeName.java
|
|
# Search for the word "uncomment" and uncomment stuff according to the comments that talk about uncommenting
|
|
# Duplicate the declaration a normal attribute (nothings special in SVG mode, etc.). Let's use "alt", since it's the first one.
|
|
# In the duplicate, replace ALT with the new name in all caps and "alt" with the new name in quotes in lower case.
|
|
# Search for "ALT,", duplicate that line and change the duplicate to say the new name in all caps followed by comma.
|
|
# Save.
|
|

|

# Copy and paste the output into nu/validator/htmlparser/impl/AttributeName.java replacing the text below the comment "START GENERATED CODE" and above the very last "}".
|

## How to add an element
|
|
|
|
# First, add an entry to parser/htmlparser/nsHTMLTagList.h or dom/svg/SVGTagList.h!
|
|
# Then, starting from the root of a mozilla-central checkout
|
|
cd parser/html/java/
|
|
make sync
|
|
# now you have a clone of https://github.com/validator/htmlparser/tree/master in parser/html/java/htmlparser/
|
|

|
|
$EDITOR nu/validator/htmlparser/impl/ElementName.java
|
|
# Search for the word "uncomment" and uncomment stuff according to the comments that talk about uncommenting
|
|
# Duplicate the declaration a normal element. Let's use "bdo", since it's the first normal one.
|
|
# In the duplicate, replace BDO with the new name in all caps and "bdo" with the new name in quotes in lower case (twice).
|
|
# Search for "BDO,", duplicate that line and change the duplicate to say the new name in all caps followed by comma.
|
|
# Save.
