46365cf8be fix(completions/zsh.rs): Fix completion of long option values
Long options take their argument either in the next word or after an
equals sign, but the Zsh completion specified that they take it either
in the same word with no separator or in the next word. See the
documentation of the Zsh _arguments function for more information.

63cc4bc6a7 Test for Issue 1135
It looks like required_unless_one has incorrect behavior if the
argument it applies to also has a short form.

tests: adds tests for using possible_values with Arg::case_insensitive 2017-11-28 08:57:04 -05:00
Kevin K

api: Adds Arg::case_insensitive(bool) which allows matching Arg::possible_values without worrying about ASCII case
When used with `Arg::possible_values` it allows the argument value to pass validation even if
the case differs from that of the specified `possible_value`.

```rust
let m = App::new("pv")
    .arg(Arg::with_name("option")
        .long("--option")
        .takes_value(true)
        .possible_value("test123")
        .case_insensitive(true))
    .get_matches_from(vec![
        "pv", "--option", "TeSt123",
    ]);

assert!(m.value_of("option").unwrap().eq_ignore_ascii_case("test123"));
```

This setting also works when multiple values can be defined:

```rust
let m = App::new("pv")
    .arg(Arg::with_name("option")
        .short("-o")
        .long("--option")
        .takes_value(true)
        .possible_value("test123")
        .possible_value("test321")
        .multiple(true)
        .case_insensitive(true))
    .get_matches_from(vec![
        "pv", "--option", "TeSt123", "teST123", "tESt321"
    ]);

let matched_vals = m.values_of("option").unwrap().collect::<Vec<_>>();
assert_eq!(&*matched_vals, &["TeSt123", "teST123", "tESt321"]);
```

fb08bb5dd5 refactor: removes unused imports on nightly via cfg directive
If one is using a nightly Rust compiler they should compile clap
with the `nightly` feature.

```toml
[dependencies]
clap = { version = "2.27", features = ["nightly"] }
```

This isn't required for compilation to succeed, only to take
advantage of any nightly features used by clap.

If one is compiling with `#[deny(warnings)]` this commit will cause
compilation to fail if one *does not* compile with the `nightly`
since `std::ascii::AsciiExt` is no longer required in in multiple
files as of the latest Rust nightly (Nov 6th, 2017).

Closes #1095

e67a061bcf docs: add html_root_url attribute
This doc attribute is used by rustdoc when generating documentation
for other crates that depend on this crate. With the html_root_url,
rustdoc will be able to generate correct links into this crate.

See C-HTML-ROOT in the Rust API Guidelines for more information:
https://rust-lang-nursery.github.io/api-guidelines/documentation.html#crate-sets-html_root_url-attribute-c-html-root

A version-sync check was added to ensure that the URL is kept up to
date when the crate version changes.

b93870c10a feat: use textwrap crate for wrapping help texts
The textwrap crate uses a simpler linear-time algorithm for wrapping
the text. The current algorithm in wrap_help uses several O(n) calls
to String::insert and String::remove, which makes it potentially
quadratic in complexity.

Comparing the 05_ripgrep benchmark at commits textwrap~2 and textwrap
gives this result on my machine:

 name              before ns/iter  after ns/iter  diff ns/iter   diff %
 build_app_long    22,101          21,099               -1,002   -4.53%
 build_app_short   22,138          21,205                 -933   -4.21%
 build_help_long   514,265         284,467            -229,798  -44.68%
 build_help_short  85,720          85,693                  -27   -0.03%
 parse_clean       23,471          22,859                 -612   -2.61%
 parse_complex     29,535          28,919                 -616   -2.09%
 parse_lots        422,815         414,577              -8,238   -1.95%

As part of this commit, the wrapping_newline_chars test was updated.
The old algorithm had a subtle bug where it would break lines too
early. That is, it wrapped the text like

    ARGS:
        <mode>    x, max, maximum   20 characters, contains
                  symbols.
                  l, long           Copy-friendly,
                  14 characters, contains symbols.
                  m, med, medium    Copy-friendly, 8
                  characters, contains symbols.";

when it should really have wrapped it like

    ARGS:
        <mode>    x, max, maximum   20 characters, contains
                  symbols.
                  l, long           Copy-friendly, 14
                  characters, contains symbols.
                  m, med, medium    Copy-friendly, 8
                  characters, contains symbols.";

Notice how the word "14" was incorrectly moved to the next line. There
is clearly room for the word on the line with the "l, long" option
since there is room for "contains" just above it.

I'm not sure why this is, but the algorithm in textwrap handles this
case correctly.

564c5f0f17 fix: allow final word to be wrapped in wrap_help
Before, inserting a newline did not move the prev_space index forward.
This meant that the next word was measured incorrectly since the
length was measured back to the word before the newly inserted
linebreak.

aff4ba18da fix: include final character in line lenght
Before, wrapping the help text at, say, 80 characters really meant
that every line could be at most 79 characters wide.

Lines can now be up to and including avail_chars columns wide.

If needed, a desired margin or padding can be subtracted from the
avail_chars argument at a later point.

refactor: refactors the internals a bit
Flags, Opts, and Positionals now store their internals using compartmented Base, Valued, and
Switched structs to keep the code duplication down and make it easier to maintain.

Iniside the src/app/parser.rs there have been several changes to make reasoning about the code
easier. Primarily moving related sections out of the large get_matches_with into their own

* feat: adds App::with_defaults to automatically use crate_authors! and crate_version! macros

One can now use

```rust
let a = App::with_defaults("My Program");

// same as
let a2 = App::new("My Program")
	.version(crate_version!())
	.author(crate_authors!());
```

Closes #600

* imp(YAML Errors): vastly improves error messages when using YAML

When errors are made while developing, the panic error messages have
been improved instead of relying on the default panic message which is
extremely unhelpful.

Closes #574

* imp(Completions): uses standard conventions for bash completion files, namely '{bin}.bash-completion'

Closes #567

* imp(Help): automatically moves help text to the next line and wraps when term width is determined to be too small, or help text is too long

Now `clap` will check if it should automatically place long help
messages on the next line after the flag/option. This is determined by
checking to see if the space taken by flag/option plus spaces and values
doesn't leave enough room for the entirety of the help message, with the
single exception of of if the flag/option/spaces/values is less than 25%
of the width.

Closes #597

* tests: updates help tests to new forced new line rules

* fix(Groups): fixes some usage strings that contain both args in groups and ones that conflict with each other

Args that conflict *and* are in a group will now only display in the
group and not in the usage string itself.

Closes #616

* chore: updates dep graph

* test: `require_unless_one` with second argument

Add the `require_unless_one_2` test. This tests that when the second
argument in the array is used at the command line, that the required
argument is not present. This test was added because it appears the
`require_unless_one` function only works for the first argument in the
array.

* Fix: assertions for test

The assertions did not check for the `infile` to be present.

The strategy is to copy the template from the the reader to wrapped stream

to the wrapped stream.
The copy from template is then resumed, repeating this sequence until reading
the complete template.

Tags arg given inside curly brackets:
Valid tags are:
    * `{bin}`         - Binary name.
    * `{version}`     - Version number.
    * `{author}`      - Author information.
    * `{usage}`       - Automatically generated or given usage string.
    * `{all-args}`    - Help for all arguments (options, flags, positionals arguments,
                        and subcommands) including titles.
    * `{unified}`     - Unified help for options and flags.
    * `{flags}`       - Help for flags.
    * `{options}`     - Help for options.
    * `{positionals}` - Help for positionals arguments.
    * `{subcommands}` - Help for subcommands.

04b5b074d1 refactor(HELP): A new Help Engine
The largest organizational change is that methods used to generate the help are
implemented by the Help object and not the App, FlagBuilder, Parser, etc.

The new code is based heavily on the old one with a few minor modifications
aimed to reduce code duplication and coupling between the Help and the rest
of the code.

The new code turn things around: instead of having a HelpWriter that holds an
AnyArg object and a method that is called with a writer as argument,
there is a Help Object that holds a writer and a method that is called with a
writer as an argument.

There are still things to do such as moving `create_usage` outside the Parser.

The peformance has been affected, probably by the use of Trait Objects. This
was done as a way to reduce code duplication (i.e. in the unified help code).
This performance hit should not affect the usability as generating and printing
the help is dominated by user interaction and IO.

The old code to generate the help is still functional and is the active one.
The new code has been tested against the old one by generating help strings
for most of the examples in the repo.

85b11468b0 fix: Stop lonely hyphens from causing panic
The method `starts_with` as implemented for the `OsStrExt2` trait on
`OsStr` assumed that the needle given is shorter than the haystack. When
this is not the case, the method panics due to an attempted
out-of-bounds access on the byte representation of `self`. Problematic
if, say, an end-user gives us `"-"` and the library tries to see if that
starts with `"--"`.

Fortunately, slices already implement a `starts_with` method, and we can
delegate to it.

This *does* create a semantics change: if both `self` and the needle
have length 0, this implementation will return `true`, but the old
implementation would return `false`. Based on the test suite still
passing, acknowledging the vacuous truth doesn't seem to cause any
problems.

8988853fb8 imp(ArgMatcher): huge refactor and deduplication of code
Tons of code has been moved into functions, deduplicated, made much
easier to read, maintain, and understand. Comments still need to be
added, but that will happen shortly. Modules have also been moved around
to follow Rust conventions and best practices.

All functionality remains exactly the same
