Language Mode Improvements in Epsilon 14
- When no region is highlighted, comment-region now operates on
the current line.
- The new comment-region-options variable has bits that
control how comment-region behaves: whether comments should be
indented, whether indented comments should be recognized, and if blank
lines should be skipped. Any mode can define a variable that includes
its name, such as python-comment-region-options, and comment-region
will use those settings in place of comment-region-options.
- The new NSIS mode supports editing .nsi files, adding variables
auto-show-nsis-delimiters and nsis-auto-show-delim-chars.
- A new mode supports the R language, adding variables
compile-rmode-cmd, rmode-indent,
auto-show-rmode-delimiters, rmode-auto-show-delim-chars,
rmode-indent-to-comment, and rmode-tab-override.
- C mode now works with more varieties of JavaScript's syntax for
defining functions, and its syntax highlighting now supports
JavaScript's template literals (backquote-surrounded and with
interpolated expressions).
- The new c-align-inherit variable controls how much extra
indentation lines specifying C++ inheritance (those following a line
ending in : in a multi-line function header) should receive. A value
of -1 indents it like any other continuation line.
- The tag-options variable's new bit 2 (now the default)
makes the select-tag-file command look up the directory
hierarchy from the current file when suggesting a new tag file.
- Epsilon now tries to auto-detect when a here document in
Perl or PHP contains HTML
code, and color it appropriately. New variables
perl-heredoc-syntax, php-heredoc-syntax, and
shell-heredoc-syntax configure this. For each of Perl, PHP, and
Shell mode, you can make Epsilon assume here
documents are always HTML (or TeX), let Epsilon try to detect the
right language, or only color here blocks as HTML or TeX when the here
document's terminating string ends in ".html" or ".tex" (as in
previous versions).
- In Makefiles, Alt-i
(list-make-preprocessor-conditionals) now recognizes both Gnu
Make and Microsoft Nmake syntax for conditionals on all systems,
instead of choosing which one to recognize based on whether the
Windows version of Epsilon was running or not.
- Python mode now colors function names
with a specific color, as in most other modes.
- TeX mode's matching delimiter highlighting
now skips over delimiters inside/outside comments or math mode,
depending on whether the original delimiter was inside such blocks.
- Many Shift-F1 context help default
definitions were changed to search the web instead of looking for
installed help files. Such definitions may now use two new formats to
perform a site-specific web search. These shorthand codes use the new
context-help-site-search and
context-help-site-search-lucky variables. Code in .m and .js
files now use specific rules instead of the generic C mode rule. The
context-help-rule-objc variable was added for the former. The
commands
select-help-files and search-all-help-files were
removed, since they only worked with ancient help file formats.
- When C mode scans for function definitions,
it skips over the standard macros
_ANSI_ARGS , __P , and
PROTO that can appear within their signatures. You can now expand
this list of macro names by modifying the new
c-prototype-macro-names variable. And Epsilon now uses this list
in more contexts.
- C mode's c-align-open-paren variable now understands a new
option. Set it to 2 to make Epsilon use alternate logic when indenting
lines within a multi-line expression, depending on what character
appears before the line break.
- C mode no longer thinks C++14's use of ' as a
digit separator in numeric constants begins a character constant.
Tagging and displaying the current function's name work better with
C++ template syntax. C, C++, and Java keywords added in more recent
versions of those languages are now colored as keywords.
- You can now set the c-align-contin-lines variable to -1 if
you don't want to limit alignment rules by column. This value acts
like an infinitely large value.
- When parsing the buffer for the name of the current function, C
mode assumes by default that a
} right brace character found
at the left margin marks the end of a top-level block (such as a
function, class, or structure definition). If you must edit code
formatted with the } of inner blocks also on the left
margin, you can now set the new c-quick-scan variable to zero.
(On very large files, this can make updating the function name shown
on the mode line much slower.)
- Epsilon now recognizes that it should use
Shell mode for more types of files.
