" *** Some syntax quirks of newLISP and how this file treats them: ***

" * In the following text, the word "character" refers to the ASCII
"   characters, and the word "symbol" to the lisp symbols (= atoms).
"
" * All built-in symbols are in the same class (Statement). Functions,
"   definitions, macros and control structures aren't distinguished.
"
" * The quoting character ' (apostrophe) is allowed anywhere, even
"   before closing parenthesis.
"
" * The comma character , makes a symbol by itself and need not be
"   separated from adjacent symbols.
"
" * Brackets [ ] and braces { } are allowed in symbols, even unmatched
"   ones. They albeit will break the Vim parentheses matching logic.
"
" * Special syntax for : character (colon) is underway. Meantime it is
"   just highlighted and not checked otherwise.
"
" * newLISP sometimes allows numbers, symbols or strings to follow one
"   another without a separator (like 1.2.3e4e5, which is valid and
"   equal to three tokens 1.2 .3e4 e5). Such a beast is rather a typo
"   than  someones intent, so it is highlighted as error.
"
" * If a backlash character \ in a quoted string is not followed by
"   a valid escape sequence, the interpreter doesn't alarm you, it just
"   silently removes this character from the string. E.g. the string
"   "a\b" is equal to the string "ab". Again, this is rather a typo than
"   someones intent, so it is highlighted as error.
"
" * This syntax file requires the Vim version 7.0 or newer. It may or
"   may not work with the Vim 6.x, although I haven't tested this.
"
" * New in this version: this is a major release, many changes in code.
"   Beware of fresh bugs! Also got in sync with newLISP 10.3.0 release.

Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
