Vim Script Functions: List, Dictionary, Float, and Blob Manipulation

substitute() strpart() get part of a string using byte index strcharpart() get part of a string using char index slice() take a slice of a string, using char index in Vim9 script strgetchar() get character from a string using char index expand() expand special keywords expandcmd() expand a command like done for `:edit` iconv() convert text from one encoding to another byteidx() byte index of a character in a string byteidxcomp() like byteidx() but count composing characters charidx() character index of a byte in a string utf16idx() UTF-16 index of a byte in a string repeat() repeat a string multiple times eval() evaluate a string expression execute() execute an Ex command and get the output win_execute() like execute() but in a specified window trim() trim characters from a string gettext() lookup message translation List manipulation: *list-functions* get() get an item without error for wrong index len() number of items in a List empty() check if List is empty insert() insert an item somewhere in a List add() append an item to a List extend() append a List to a List extendnew() make a new List and append items remove() remove one or more items from a List copy() make a shallow copy of a List deepcopy() make a full copy of a List filter() remove selected items from a List map() change each List item mapnew() make a new List with changed items foreach() apply function to List items reduce() reduce a List to a value slice() take a slice of a List sort() sort a List reverse() reverse the order of items in a List uniq() remove copies of repeated adjacent items split() split a String into a List join() join List items into a String range() return a List with a sequence of numbers string() String representation of a List call() call a function with List as arguments index() index of a value in a List or Blob indexof() index in a List or Blob where an expression evaluates to true max() maximum value in a List min() minimum value in a List count() count number of times a value appears in a List repeat() repeat a List multiple times flatten() flatten a List flattennew() flatten a copy of a List Dictionary manipulation: *dict-functions* get() get an entry without an error for a wrong key len() number of entries in a Dictionary has_key() check whether a key appears in a Dictionary empty() check if Dictionary is empty remove() remove an entry from a Dictionary extend() add entries from one Dictionary to another extendnew() make a new Dictionary and append items filter() remove selected entries from a Dictionary map() change each Dictionary entry mapnew() make a new Dictionary with changed items foreach() apply function to Dictionary items keys() get List of Dictionary keys values() get List of Dictionary values items() get List of Dictionary key-value pairs copy() make a shallow copy of a 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()

This section outlines various functions available in Vim script for manipulating lists, dictionaries, floating-point numbers, and blobs. It covers functions for extracting parts of strings, expanding special keywords, encoding conversion, indexing, repetition, evaluation, execution of commands, trimming, and translation (string functions). Then, it lists list manipulation functions, including adding, inserting, removing, copying, filtering, mapping, sorting, splitting, joining, and indexing elements. Next, it describes dictionary manipulation functions for adding, removing, filtering, mapping, and retrieving keys and values. It also details functions for floating-point computations, such as conversion, absolute value, rounding, logarithms, exponents, trigonometric functions, and checks for infinity or NaN. Finally, it mentions blob manipulation functions, starting with blob2list().
