# Re: [RFC] Add xfail tests for || form of completion matchers

Attached is a new version of the patch, which should address most of
matching logic. Below are my replies to points not addressed by the
patch.

I iterations over several permutations of terms in the docs and found
that this one seems to work best:

"When the user invokes completion, the _current word_ on the command
line is used to generate a _match pattern_ defining which
_completions_ are considered _matches._"

This also matches the use of these terms in the majority of the
manual. Where it doesn't match in compwid.yo, I've changed the text so
that it does.

I used "completions" anyway, because it feels like the most natural
and concise word to use for this purpose. It doesn't appear to cause
any ambiguities in the text.

I'm not sure what these tests should look like. So, I didn't add them.

No, it does not appear to work like that in vanilla zsh:

% PS1='%# ' zsh -f
% _tst() { compadd veryverylongfile.c }
% tst v.c^B^B\t

The word 'v.c' in this example will not get completed, no matter where
you put the cursor.

Subject: [PATCH] Define correct behavior of || completion matchers

* Add xfail tests to show how :||= matchers should behave in order to
provide completion features that cannot be implemented with :|=
matchers.
* Update compwid.yo to further describe the correct behavior.
* Update compwid.yo to use completion terminology more consistently.

Literal characters match -only themselves, question marks match any character, and character -classes are formed as for globbing and match any character in the given -set. - -Correspondence classes are defined like character classes, but with two -differences: they are delimited by a pair of braces, and negated classes -are not allowed, so the characters tt(!) and tt(^) have no special -meaning directly after the opening brace. They indicate that a range of -characters on the line match a range of characters in the trial -completion, but (unlike ordinary character classes) paired according to -the corresponding position in the sequence. For example, to make any -ASCII lower case letter on the line match the corresponding upper case -letter in the trial completion, you can use tt(m:{a-z}={A-Z})' -(however, see below for the recommended form for this). More -than one pair of classes can occur, in which case the first class before -the tt(=) corresponds to the first after it, and so on. If one side has -more such classes than the other side, the superfluous classes behave -like normal character classes. In anchor patterns correspondence classes -also behave like normal character classes. - -The standard tt([:)var(name)tt(:])' forms described for standard shell -patterns (see -ifnzman(noderef(Filename Generation))\ -ifzman(the section FILENAME GENERATION in zmanref(zshexpn))) -may appear in correspondence classes as well as normal character -classes. The only special behaviour in correspondence classes is if -the form on the left and the form on the right are each one of -tt([:upper:]), tt([:lower:]). In these cases the -character in the word and the character on the line must be the same up -to a difference in case. Hence to make any lower case character on the -line match the corresponding upper case character in the trial -completion you can use tt(m:{[:lower:]}={[:upper:]})'. Although the -matching system does not yet handle multibyte characters, this is likely -to be a future extension, at which point this syntax will handle -arbitrary alphabets; hence this form, rather than the use of explicit -ranges, is the recommended form. In other cases -tt([:)var(name)tt(:])' forms are allowed. If the two forms on the left -and right are the same, the characters must match exactly. In remaining -cases, the corresponding tests are applied to both characters, but they -are not otherwise constrained; any matching character in one set goes -with any matching character in the other set: this is equivalent to the -behaviour of ordinary character classes. - -The pattern var(tpat) may also be one or two stars, tt(*)' or -tt(**)'. This means that the pattern on the command line can match -any number of characters in the trial completion. In this case the -pattern must be anchored (on either side); in the case of a single -star, the var(anchor) then determines how much of the trial completion -is to be included DASH()- only the characters up to the next appearance of -the anchor will be matched. With two stars, substrings matched by -the anchor can be matched, too. In the forms that include two -anchors, tt(*)' can match characters from the additional anchor -DASH()- var(lanchor) with tt(r) or var(ranchor) with tt(l). - -Examples: - -The keys of the tt(options) association defined by the tt(parameter) -module are the option names in all-lower-case form, without -underscores, and without the optional tt(no) at the beginning even -though the builtins tt(setopt) and tt(unsetopt) understand option names -with upper case letters, underscores, and the optional tt(no). The -following alters the matching rules so that the prefix tt(no) and any -underscore are ignored when trying to match the trial completions -generated and upper case letters on the line match the corresponding -lower case letters in the words: - -example(compadd -M 'L:|[nN][oO]= M:_= M:{[:upper:]}={[:lower:]}' - \ -${(k)options} )
-
-The first part says that the pattern tt([nN][oO])' at the beginning
-(the empty anchor before the pipe symbol) of the string on the
-line matches the empty string in the list of words generated by
-completion, so it will be ignored if present. The second part does the
-same for an underscore anywhere in the command line string, and the
-third part uses correspondence classes so that any
-upper case letter on the line matches the corresponding lower case
-letter in the word. The use of the upper case forms of the
-specification characters (tt(L) and tt(M)) guarantees that what has
-already been typed on the command line (in particular the prefix
-tt(no)) will not be deleted.
-
-Note that the use of tt(L) in the first part means that it matches
-only when at the beginning of both the command line string and the
-trial completion. I.e., the string tt(_NO_f)' would not be
-completed to tt(_NO_foo)', nor would tt(NONO_f)' be completed to
-tt(NONO_foo)' because of the leading underscore or the second
-tt(NO)' on the line which makes the pattern fail even though they are
-otherwise ignored. To fix this, one would use tt(B:[nN][oO]=)'
-instead of the first part. As described above, this matches at the
-beginning of the trial completion, independent of other characters or
-substrings at the beginning of the command line word which are ignored
-by the same or other var(match-spec)s.
-
-The second example makes completion case insensitive.  This is just
-the same as in the option example, except here we wish to retain the
-characters in the list of completions:
-
-
-This makes lower case letters match their upper case counterparts.
-To make upper case letters match the lower case forms as well:
-
-
-A nice example for the use of tt(*) patterns is partial word
-completion. Sometimes you would like to make strings like tt(c.s.u)'
-complete to strings like tt(comp.source.unix)', i.e. the word on the
-command line consists of multiple parts, separated by a dot in this
-example, where each part should be completed separately DASH()- note,
-however, that the case where each part of the word, i.e. tt(comp)',
-tt(source)' and tt(unix)' in this example, is to be completed from
-separate sets of matches
-is a different problem to be solved by the implementation of the
-completion widget.  The example can be handled by:
-
-  - comp.sources.unix comp.sources.misc ...)
-
-The first specification says that var(lpat) is the empty string, while
-var(anchor) is a dot; var(tpat) is tt(*), so this can match anything
-except for the tt(.)' from the anchor in
-the trial completion word.  So in tt(c.s.u)', the matcher sees tt(c)',
-followed by the empty string, followed by the anchor tt(.)', and
-likewise for the second dot, and replaces the empty strings before the
-anchors, giving tt(c)[tt(omp)]tt(.s)[tt(ources)]tt(.u)[tt(nix)]', where
-the last part of the completion is just as normal.
-
-With the pattern shown above, the string tt(c.u)' could not be
-completed to tt(comp.sources.unix)' because the single star means
-that no dot (matched by the anchor) can be skipped. By using two stars
-as in tt(r:|.=**)', however, tt(c.u)' could be completed to
-tt(comp.sources.unix)'. This also shows that in some cases,
-especially if the anchor is a real pattern, like a character class,
-the form with two stars may result in more matches than one would like.
-
-The second specification is needed to make this work when the cursor is
-in the middle of the string on the command line and the option
-tt(COMPLETE_IN_WORD) is set. In this case the completion code would
-normally try to match trial completions that end with the string as
-typed so far, i.e. it will only insert new characters at the cursor
-position rather than at the end.  However in our example we would like
-the code to recognise matches which contain extra characters after the
-string on the line (the tt(nix)' in the example).  Hence we say that the
-empty string at the end of the string on the line matches any characters
-at the end of the trial completion.
-
-More generally, the specification
-
-example(compadd -M 'r:|[.,_-]=* r:|=*' ... )
-
-allows one to complete words with abbreviations before any of the
-characters in the square brackets.  For example, to
-with the above in effect, you can just type tt(very.c) before attempting
-completion.
-
-The specifications with both a left and a right anchor are useful to
-complete partial words whose parts are not separated by some
-special character. For example, in some places strings have to be
-completed that are formed tt(LikeThis)' (i.e. the separate parts are
-determined by a leading upper case letter) or maybe one has to
-complete strings with trailing numbers. Here one could use the simple
-form with only one anchor as in:
-
-example(compadd -M 'r:|[[:upper:]0-9]=* r:|=*' LikeTHIS FooHoo 5foo123 5bar234)
-
-But with this, the string tt(H)' would neither complete to tt(FooHoo)'
-nor to tt(LikeTHIS)' because in each case there is an upper case
-letter before the tt(H)' and that is matched by the anchor. Likewise,
-a tt(2)' would not be completed. In both cases this could be changed
-by using tt(r:|[[:upper:]0-9]=**)', but then tt(H)' completes to both
-tt(LikeTHIS)' and tt(FooHoo)' and a tt(2)' matches the other
-strings because characters can be inserted before every upper case
-letter and digit. To avoid this one would use:
-
-    LikeTHIS FooHoo foo123 bar234)
-
-By using these two anchors, a tt(H)' matches only upper case tt(H)'s that
-are immediately preceded by something matching the left anchor
-tt([^[:upper:]0-9])'. The effect is, of course, that tt(H)' matches only
-the string tt(FooHoo)', a tt(2)' matches only tt(bar234)' and so on.
-
