Returns true if a matcher was assigned to this lexer for scanning.

Returns true if this matcher has a pattern.

Returns true if this matcher has a pattern.

predict match hash 0 <= hash() < Const::HASH, must be additive: hash(h,b+1) = hash(h,b)+1 modulo Const::HASH.

move cursor home (0,0)

Translate group capture index to id pair (index,name)

a .gitignore or similar file was encountered

Returns true if looking at indent.

file indexing hash 0 <= indexhash() < 65536, must be additive: indexhash(x,b+1) = indexhash(x,b)+1 modulo 2^16.

Initialize the state after (re)setting the input source, auto-detects UTF BOM in FILE* input if the file size is known.

Initialize specialized pattern search methods to advance the engine to a possible match

initial part of a file is binary

specify input to read for matcher, when input is a regular file then try mmap for zero copy overhead

Update ranges to include range [lo,hi] by merging overlapping and adjacent ranges into one range.

Inserts or appends an indent stop position, keeping indent stops sorted.

Set interactive input with buffer size of 1 to read data bytewise which is very slow.

Return true if this set of ranges intersects with ranges rs, i.e. this set has at least one range [lo',hi'] that overlaps with a range [lo,hi] in rs s

Return true if this set of ranges intersects with ranges rs, i.e. this set has at least one range [lo',hi'] that overlaps with a range [lo,hi] in rs s

enable invert (reverse video)

return true if pathname has a (tar) compress (Z) filename extension

return true if at a |, \n or OR then return true when found and skip over it, otherwise return false

return true if the pattern pointer starts with an AND, OR, or NOT operator and skip over it

return true if pathname has a zip filename extension

check if lower or upper case

check if lower case

Get the std::istream of this Input object, returns NULL when this Input is not a std::istream.

check if upper case

Return true if Unicode word character.

output quoted string in JSON

output a match as a quoted string in JSON

jump to the specified row

wait for next raw key press within VKey::TIMEOUT ms

Returns the position of the last indent stop.

create a new leaf node.

Truncate the AbstractMatcher::text length of the match to n characters in length and reposition for next match.

Lexer exceptions.

dump one line of hex

Returns the line of input (excluding `\n`) as a string containing the matched text as a substring.

return pointer to the end of the query search line

return the length of the query search line as a number of screen columns displayed

return number of character positions on the query search line up to the current screen Query::col_, taking UTF-8 wide characters into account

return pointer to character in the query search line at screen col, taking UTF-8 double width characters into account

return the length of the query search line as the number of UTF-8 wide characters

Set or change the starting line number of the last match.

Returns the inclusive ending line number of the match in the input character sequence.

Returns the number of lines that the match spans.

convert to lower case if c is a letter a-z, A-Z.
