Except for tt(compdisplay) these builtin commands are very +specialised and thus not very interesting when writing your own +completion functions. In short, these builtin commands are: + +startitem() +item(tt(compdisplay) var(name) var(string) var(defs) ...)( +The var(defs) are strings should be of the form +`var(str)tt(:)var(descr)' (the intended use is that the var(descr) +describes the var(str)) and tt(compdisplay) will convert them to +strings in which the colon is replaced by the var(string) given as the +second argument and spaces are inserted before that so that they are +aligned over all strings. These resultings strings are then assigned +to an array with the var(name) given as the first argument. +) +item(tt(compdescribe))( +This is used by the tt(_describe) function to build the displays for +the matches and to get the strings to add as matches with their +options. The first call has to give the tt(-i) or tt(-I) option as the +first argument. In the first case, display strings without the +descriptions will be generated, inthe second case, the string used to +separate the matches from their descriptions has to be given as the +second argument and the descriptions (if any) will be shown. All other +arguments are like the definition arguments to tt(_describe) itself. + +Once tt(compdescribe) has been called with either the tt(-i) or the +tt(-I) option, it can be repeatedly called with the tt(-g) option and +the names of five arrays as its arguments. This will step through the +different sets of matches and store the options in the first array, +the strings with descriptions in the second, the matches for these in +the third, the strings without descriptions in the fourth, and the +matches for them in the fifth array. These are then directly given to +tt(compadd) to register the matches with the completion code. +) +item(tt(comparguments))( +This is used by the tt(_arguments) function to do the argument and +command line parsing. Like tt(compdescribe) it has an option tt(-i) to +do the parsing and initialize some internal state and various options +to access the state information to decide what should be completed. +) +item(tt(compvalues))( +Like tt(comparguments), but for the tt(_values) function. +) +enditem() -- cgit 1.4.1
