Vim Script Functions: Data Types, Computation, Variables, and Text Manipulation

Dictionary deepcopy() make a full copy of a Dictionary string() String representation of a Dictionary max() maximum value in a Dictionary min() minimum value in a Dictionary count() count number of times a value appears Floating point computation: *float-functions* float2nr() convert Float to Number abs() absolute value (also works for Number) round() round off ceil() round up floor() round down trunc() remove value after decimal point fmod() remainder of division exp() exponential log() natural logarithm (logarithm to base e) log10() logarithm to base 10 pow() value of x to the exponent y sqrt() square root sin() sine cos() cosine tan() tangent asin() arc sine acos() arc cosine atan() arc tangent atan2() arc tangent sinh() hyperbolic sine cosh() hyperbolic cosine tanh() hyperbolic tangent isinf() check for infinity isnan() check for not a number Blob manipulation: *blob-functions* blob2list() get a list of numbers from a blob list2blob() get a blob from a list of numbers reverse() reverse the order of numbers in a blob Other computation: *bitwise-function* and() bitwise AND invert() bitwise invert or() bitwise OR xor() bitwise XOR sha256() SHA-256 hash rand() get a pseudo-random number srand() initialize seed used by rand() Variables: *var-functions* type() type of a variable islocked() check if a variable is locked funcref() get a Funcref for a function reference function() get a Funcref for a function name getbufvar() get a variable value from a specific buffer setbufvar() set a variable in a specific buffer getwinvar() get a variable from specific window gettabvar() get a variable from specific tab page gettabwinvar() get a variable from specific window & tab page setwinvar() set a variable in a specific window settabvar() set a variable in a specific tab page settabwinvar() set a variable in a specific window & tab page garbagecollect() possibly free memory Cursor and mark position: *cursor-functions* *mark-functions* col() column number of the cursor or a mark virtcol() screen column of the cursor or a mark line() line number of the cursor or mark wincol() window column number of the cursor winline() window line number of the cursor cursor() position the cursor at a line/column screencol() get screen column of the cursor screenrow() get screen row of the cursor screenpos() screen row and col of a text character virtcol2col() byte index of a text character on screen getcurpos() get position of the cursor getpos() get position of cursor, mark, etc. setpos() set position of cursor, mark, etc. getmarklist() list of global/local marks byte2line() get line number at a specific byte count line2byte() byte count at a specific line diff_filler() get the number of filler lines above a line screenattr() get attribute at a screen line/row screenchar() get character code at a screen line/row screenchars() get character codes at a screen line/row screenstring() get string of characters at a screen line/row charcol() character number of the cursor or a mark getcharpos() get character position of cursor, mark, etc. setcharpos() set character position of cursor, mark, etc. getcursorcharpos() get character position of the cursor setcursorcharpos() set character position of the cursor Working with text in the current buffer: *text-functions* getline() get a line or list of lines from the buffer getregion() get a region of text from the buffer getregionpos() get a list of positions for a region setline() replace a line in the buffer append() append line or list of lines in the buffer indent() indent of a specific line cindent() indent according to C indenting lispindent() indent according to Lisp indenting nextnonblank() find next non-blank line prevnonblank() find previous non-blank line search() find a match for

This section covers Vim script functions for dictionaries (copying, string representation, min/max, counting), floating-point computations (conversion, math functions, NaN checks), and blobs (converting to/from lists, reversing). It also includes bitwise operations, hashing, and random number generation. Functions for getting/setting variables in different scopes (buffers, windows, tab pages), checking variable types/lock status, and garbage collection are described. Cursor and mark position functions (getting/setting position, line/column numbers, mark lists) are outlined. Finally, it details text manipulation functions for the current buffer: getting/setting lines, appending, indenting, and searching.
