Well, I remember that there are bugs. But I failed to reproduce it today.
Maybe, I was using GNU TeXmacs 1.99.12. I should have submitted bug report.

Unfortunately, there are bugs from
`Language(C++): re-impl coloring using improved string_parser`
to
`Language(DOT): tuning on dot-edit`.
I will fix it next weekend and add the missing test cases.

Thanks Darcy. With Covid-19 raging, it is indeed a top priority to
focus on the community. You are also in an ideal position for guiding
Chinese students who may wish to help in the GSoC context.
I am extremely busy, but hope to contribute a few ideas as well later.
Best wishes, --Joris

OK, for the next several months, only bug fixes will be committed.
And last week, we have some good news on GSoC. For the next serveral
months, I will focus more on the community:
1. Write documentation on devel (https://github.com/texmacs/devel)
for new contributors
2. Review pull requests
3. ...

Hi Darcy,
I noticed your recent changes.
Please be very careful when commiting changes,
since version 2.1 is still approaching, despite the Covid-19 setback.
Best wishes, --Joris

Recent tree months, I wrote some parsers under src/Data/Parser:
+ blanks_parser
+ escaped_char_parser
+ identifier_parser
+ inline_comment_parser
+ keyword_parser
+ number_parser
+ operator_parser
+ string_parser (TODO: multi-line support)
On top of these parsers, I rewrite various part of xxx_language.cpp .
I didn't use a higher-level abstraction like packrat-parser. In my
opinion,for now, low level small parsers written in C++ should work
fine.
Most programing languages are similar in syntax. Doing simple
abstraction is sufficient for syntax highlighting.
The goal of these small parsers with `can_parser` and `do_parser` is
to minimize the time to implemented a new programming language
parser.
Below are the detailed progress:
+ dot: new composition of parsers, string_parser, keyword_parser,
operator_parser
+ cpp: new composition of parsers, string_parser
+ java/scala/python: old composition of parsers, string_parser
+ others: old composition of parsers
Composition of parsers: old vs new
Almost all xxx_language.cpp (except scheme_language.cpp) is derived
>from mathemagix_language.cpp .
I call it old-style composition of parsers. It is not efficient
enough, because, we have to re-parse the code in `get_color`.
Dive into concat_text.cpp:typeset_prog_string, we will find what
actually is `get_color` and `advance`.
The new-style composition of parsers, reduce the unnecessary
parsings in get_color.
Keyword/Operator Parser
Aims to keep the (type, keyworkd) mapping in Scheme files. Please
refer to `dot-lang.scm`.
String Parser
Currently, the String parser only support inline string. Actually,
string and multi-comment are the same type.
They both have openings and corresponding closings.
The string parser will finally support multi-line. Once it is ready,
the multi-comment parser will also be implemented
in a short time.
Recent Plans
I will continue my developments on newly-supported languages (like
dot). The goal is to make it extremely easy to
support a new language. For coloring schemes, it is another topic.
In the next one or two months, I will continue to
work on improving the xyz_parser and abc_language.
