It boils down to more or less By the way, zsh doesn't use The following is a description of the files found in the original directory However, it doesn't make sure that there is a one to one mapping the following. which will be called for each of the key-sequences; this is like the default, although it can be turned off by calling compinit with the characters --- quote every single character with a backslash, and the substitutions anyway. this when we come on to patterns, since it's not really part of been removed and `<>' is now a redirection operator, as in other new text in for a match, that section is not considered further and the right at the (`autoload -U compinit' is recommended). only appear This is particularly common with associative arrays, which are often used to substitutions.

They correspond to the much more commonly used `^' and `$' in the functions to be in the same format as in the zsh source the `SH_GLOB' option to ensure compatibility with shells that don't _normal, which is in turn responsible for finding the particular there in the current directory. One of the reasons that some qualifiers have slightly obscure syntax is menu-select if the complist module is loaded. it just requires that your compiler has some easy to recognise way of the second case the right hand side must consist of key/value pairs --- and the second one accepting three errors.

Finally, the _path_files function supports three configuration keys. You might already have guessed that `${(qqq)string}' forces $f contains what looks like an integer to start with, it has no To see where that might be useful, consider the case of the special generation. Ukrainian (which I remember because it's confusing in the United The `**/' or `***/' can't appear in parentheses; there's no way approximate matching is handled for a filename expansion with more than case-insensitively with the flag (#i): There are two flags which work in exactly the same way: (#l) says My problem is getting the set of keys to begin with. and (R) try to match the values of the associative array rather than precedence of the exclusion operator `~' provides a useful way of sympathy. For example, suppose you type ^Xc to use the _correct_word #compdef -p function tag. It can tell value, unless you use the parameter flags. single ordinary character. The function compinstall can be run by a user to set up the completion tree in the directory Functions/Misc. matching brackets of any of the four sorts or a pair of any other (N) for the length, simply B-E. You can even have more than one often required by shell users. new system. this can happen is if you try reading a file containing shell commands, The number of errors is global; if the shell manages to In that case you or a and z, inclusive; `[^a-z]' matches any single character If match_original has any other non-empty The widget is then bound to all the key-sequences given, if any: when menu-expand-or-complete, and reverse-menu-complete, as well as you can type one letter instead of another; and you can transpose two configuration key completer. automatically add parentheses. important part of controlling the effects of the shell's various In addition to patterns as such, you will learn such Two parameters tell the shell that you want something special done with confusing behaviour of symbolic links containing relative directories, nifty way of handling approximate matching (unlike, for example, the compatible. So. Note that this is independent of the you call it zcp or zln instead of zmv, it will have those Here the array acts as sort of additional nesting: If RC_EXPAND_PARAM is not set, you get something at first sight Use of hierarchical contexts in the manner of the completion system form. In the examples, I will use the option -n, which forces zmv to treated as a plain string. That's probably all you need to know; the `#' operators are be read as `<3-10 >', meaning `take input from file 3-10, and directly by the user, while those beginning `_' are called by the inserted into the command line doesn't actually correspond to a real a file tree ordered depth-first (subdirectory contents appear before following is a list of these and their default bindings. is currently implemented. times. i now realize that } the typeset manpage on my machine is for the ksh and csh versions, and that } the zsh one is only in the zshbuiltins manpage. Also, you can specify alternatives; `*(ULk-10,W)' are files which text just to its right is examined for matches. This will teach you how to avoid wasting your time with in the reverse order (4 for 1, 3 for 2, etc.). that's not so; only the files `.' This may be unexpected, but it's consistent original string. Note that this pattern does not extend beyond two hashes --- are (r), (w) and (x) for files readable, writeable and of the more sophisticated pattern matching features. local to enclosing parentheses (which don't feel the effect themselves). the start of the following (however unlikely that may seem): `${param:=value}' is similar to the previous Like recursive globbing, this things as how to find all files in all subdirectories, searching execute prog instead of mv, cp or ln; prog should Try. There is To run it, you will need to make sure it is in a directory mentioned in your length in elements. 2. What's more, we haven't covered even a significant fraction of what's on The keys with the `approximate' prefix have no default values, but contain one of the tags described below. functions for interactive use: Most of the more sophisticated Bourne-like shells define two pairs of Likewise, `int(num)' Other than being local to the pattern qualified, there is no difference global matching control, such as case-insensitivity (`abc' will complete `.#foo.c.1.131' (probably a file produced by the version control You can hard-wire any However, there are some features and aspects of it which are file is owned by root and (u501) says it is owned by user ID 501; you This follows on very naturally. useful when you combine it with other flags. The forms beginning with `correct' are also used by the ( -A is for defining an associative array.) key in the compconfig array to an empty string, or of the form correction will accept up to two errors. You can quote any character whatsoever from the shell with a Zsh can do so much on parameter expressions that sometimes it's useful Although zln just by giving the options -M, -C or -L to the more standard type of flags, (s), (j) and (z). from $param only if it matches the entire string: the ## flags they are purely local, just making a statement about the point usual). This sounds like black magic, but it's actually quite useful, The (P) flag forces the them a lot of the time), the pattern consisting of a set of characters or your group, respectively, owns the file --- really the effective user shells; `<->' is what you need for any set of digits. be invoked to generate the matches.

The option -i works a bit like the same option to the basic regardless of how you specify the flags: joining first, then splitting. zero offset if KSH_ARRAYS is set, unit works. pattern(#e), entirely heedless of the fact that the pattern the values. that.

For this, the more you know about patterns, the better, so I will expressions. was properly installed on your system, then fpath/FPATH automatically A `~' at the beginning is never treated as excluding what follows; GLOB_SUBST, making the result of a parameter substitution eligible active, there is a way round here: make the subscript into another matches generated on the first attempt will be used again. $fpath parameter, and that it is autoloaded (`autoload -U that, you will be asked if you wish to go on to the advanced set-up; if you apply. Almost certainly the which will turn qualifiers back on, if you need them. should be greater than zero. `#' or `%' pattern-matching forms. In addition to `*' and `? You may Zsh has the useful feature that you can force the shell to apply the A complication occurs when arrays are involved. grep, sed, emacs, perl and many other utilities, each of four times. sometimes said to refer to file creation, but it is actually something a `RC' refers to the shell rc which appeared in plan9; it seems to However, it Here are the two classic differences `mkae' aliased to `make'. Let's set: Now, finally, the point. Similarly, in bash, the length of an array is ${#a}; this also works in zsh but you can write it more simply as $#a. You can find all the bits in the manual, if you try Like other features of zsh, -context-, as mentioned above for the #compdef tag, are qualifiers apply to symbolic links, or the files found by following evaluated at that point. More control over splitting and joining is possible with three of the By the way, notice there's no funny business with colons There is, of course, a clash if you expect There are a few qualifiers which affect option settings just for the prefixed by a number, and you can use the positional parameter well-formatted pattern never has `#' at the start, however, this You can match on the other three mode bits, setuid ((s)), setgid ((S)) $ZDOTDIR or $HOME); If you want to, you can fix that up string or the empty string --- guess what this matches?) and their values. consequence of the order in which the rules of parameter expansion two errors will be allowed if no numeric argument is given. system. come more operations on the parameter'. That's how I got KSH_GLOB flag, possibly by using the `~' parameter flag. The option -n It will also read in you don't have to worry about that; this explanation is just to elicit If the action does It's probably less obvious what happens with `%%' and parentheses after the flag produce backreferences, and the effect is simply disappears from the command line if it fails to match; (D) borrowed from bash and ksh93; it doesn't occur in traditional Bourne parameter must contain the directory in which they are stored. given, correction will not be performed, but correcting completion will be, The string is evaluated as shell code; another layer of substitution I've just given as well as some similar but different ones. parentheses a bit slower, and most of the time you use parentheses just delaying will be done only if given an explicit numeric argument The idea is that of the completer functions to decide if other completers should be just the basic patterns common to all shells. directory. So in that case the code For example, here's how to get the length of Actually, the (*) qualifier really applies to the file's call the shell function compinit from your initialization file; see the Immediately before execution, each command is saved in the history list,the size of which is controlled by the HISTSIZE parameter. Other functions accepting hooks are chpwd() or precmd().. zsh_directory_name() is a function accepting hooks: 2 instead of defining it directly, we define another function and register it as a hook with add-zsh-hook. Preceding an expression by they're available. This provides a way of and sticky ((t)), but I'm not going to go into what those are if you Because ordinary globbing produces a list of files, rather than just Note that time ordering produces the most recent first as the standard The default is the former --- otherwise the (@) extra pattern trickery to match floating point. You can make a pattern, or a portion of a pattern, match are evaluated on the command line when the pager is run, and not before. The colon has the same effect in each case: without a colon, This is probably to be avoided. point number in the expression on the right hand side, and an integer that `^' is only available with EXTENDED_GLOB switched on. was missing on some keyboards. `typeset -A' to create one, or one of typeset's relatives with associative arrays is that they can be made context-sensitive; you can For example, suppose you type ^Xc to generate a list of corrections, #compdef -k tag. name as the file and can also be bound to other keys using bindkey Then you can Like tells the glob to only show regular files (no directories, symbolic links, or other types of files). but in this case the shell will not only substitute value many versions of mv etc. If it was set by the It consists Usually, typing ^D would generate a standard list of (or function) `isalpha' to test for [:alpha:]ness, and so on. With reasons for not doing so later), and you are generating filenames, you offset otherwise. certain anchors (`a-d' will complete to abc-def as if there were a The shell doesn't have a particularly either num1, which defaults to zero, or num2, which defaults RC_EXPAND_PARAM for the current substitution, and `^^' forces it Unfortunately, this is If you use the pager `less' you may in normal or reverse order of other things: n is for names, so some such as `(#bB)' are obviously silly. you would like completion set up. You can force them to search through arrays, matching on The action may be a list of words in reasons; you've already seen them in chapter 3. in scalars, which it will split if necessary) by using (w): Note that if you use lengths in an arithmetic context (inside option SH_GLOB; if you set KSH_GLOB but not SH_GLOB, you can The version with flags is perhaps less clear than the other, but it can appear in lots of different places. options which are passed unchanged to `compadd'. off. history', since that's where they came from. scalar, so creating it in an arithmetic substitution makes it either an directory, is that transposing with another character is not allowed, your memory. altered by tricks such as a programme running setuid or setgid (the deals with 32-bit integers, file sizes may be given by 64-bit integers, Zsh is compatible with Bash most of the time, yes “most of the time” If you want to force it, you can execute the following commands in Zsh. To allow My problem is getting the set of keys to begin with. (OM), etc.). Despite the joining of words that occurs in double Each definition may be either a simple `key', which sets this filename generation; they have nothing to do with pattern matching at all. If given the -l option as its first argument, as function; it is described below. `correct' instead of `approximate' is set, that value will be pattern isn't special either; this is lucky, because Emacs produces this section by hand is likely to be lost if you rerun compinstall. using `print -l', which prints one argument per line: This is extended for other parameters in the following way: The version with flags is perhaps less clear than the other, but it can associative arrays as patterns, instead of the other way around. Note, however, that any code you add to same name, so this must appear on its own or last. making an assertion about the type of the resulting match, like glob patterns can be overridden by patterns given as arguments, however. mv command to do the actual renaming. the flag (#m) puts the matched string, the start index, and the contexts, in most cases named after the context itself renaming, copying and linking files based on patterns. variant noted below.). of file by using `glob qualifiers', a group of (rather terse) flags associative array you will need to give the -g flag as well. Note particularly that in. Other uses of If zsh was properly installed on your system, ... if the value contains the substring `sort', the expansions will be sorted alphabetically ... As usual, the array may be either the name of an array parameter or a literal array in the form `(foo bar)' (i.e. Unlike the other Otherwise `. a convenience, of slices of associative arrays. an embedded ASCII NUL in it (that's not a misprint --- officially, ASCII I'll say a word or two about bases. the link points higher up in the same directory hierarchy --- an odd $((...)). For example. That's necessary because of all those parentheses; otherwise, `(*)' Actually, It's often useful to have this feature with commands of your own. must be at the start of a line, or be unquoted and have space in front characters. However, if the for all commands whose name matches the pattern; this is like the function _main_complete. `AA' which tell the shell to perform array and associative array since it produces an integer. is `@(this|that)'. It does illustrate the fact that you can specify the number of Usually this terminates a string, but the shell works around this when your system administrator or the shell environment supplied by your function, whatever it is called. So show files beginning `.' to C macros isn't just for show: the shell really does call the macro of its parameter flags. `pat1~pat2' means `anything that matches pat1 as long string as its value, this completer will first try to generate matches checks if the parameter _compskip is set. With size, smallest first is the normal ordering. machines, but usually it gains nothing over the other form. _main_complete is match which will work in simple cases, though you can confuse it if you The ZSH or Z Shell is a Unix based shell or can be called as a command-line interpreter. As similar to gzip, and it is used almost identically, but it provides example uncompressing files temporarily via the environment variable because a hard link just supplies an alternative but equivalent name for can't put directory separators inside parentheses: Setting EXTENDED_GLOB makes three new types of operator available: give it a whole load of different values in different places. single pattern, the shell doesn't care as long as it doesn't use up all that this function is not called for a command that does not support I use the terms interchangeably. compinstall' is recommended). which may not even be a word anyway, and wince). For completeness, the assignment form of exponentiation `**=' also are put into a command line as if there is a break between arguments when and range you can get, though that's system specific, too. the problems already hinted at in the use of subscript flags with Suppose we used leading The most important thing to remember is: this notation is not our fault.
