`clap_generate` originally intended to be "generate anything". With
`fig`, we already broke one part out. With #3174's man support, we are
also looking at keeping it separate:
- More freedom to iterate on the API
- Uniqueness (and potential weight) of its dependencies
- man generation is normally more for distribution while completions are
a mix of being distributed with the app or the app generating the
completions (which will be exacerbated if we move most completion
parsing logic to be in Rust)
So `clap_generate` is having a lot more limited of a role than the
original name conveys. I worry the generic name will be a hindrance to
people discovering and using it (yes, documentation can help but there
are limits).
I hesitated because we are on the verge of releasing 3.0. However, doing
it even later will be even more disruptive because more people will be
using it (crates.io lists ~70 people using `clap_generate`).
To ease things, we are still releasing `clap_generate` as a wrapper
around `clap_complete`.
This reverts commit 333b993481.
PR #1810's motivation was effectively "this is redundant with `\n`".
That is a fine motivation. Unfortunately, we don't have a way to force
a hard break in `clap_derive`. #2389 should help with this eventually
but we shouldn't hold up 3.0 to get that ready. So in the mean time, we
are restoring `{n}`.
We have #3230 for tracking the re-removal of it.
A lot of users expected `color` feature flag and `ColorAuto` etc to
control all colors. Having this extra flag around is easy to miss and
adds to our overall settings bloat, making it harder to find settings
people want.
This completely removes it, rather than make it deprecated like
functions in #2617, because there is extra work to mark things
deprecated as Settings and we should decide on our strategy first before
investing time in addressing that issue.
Fixes#2806
This commit removes `AppSettings::DisableVersionForSubcommand` as it's
now a moot setting with clap's default functionality of not building a
version flag unless there actually exists version information.
`clap_up` must still be changed to remove this variant instead of the
current configuration to simply rename the variant.
Before, validating UTF-8 was all-or-nothing and would cause a `panic` if
someone used the right API with non-UTF-8 input.
Now, all arguments are validated for UTF-8, unless opted-out. This
ensures a non-panicing path forward at the cost of people using the
builder API that previously did `value_of_os` need to now set this flag.
Fixes#751
Refactoring and better test cases
Refactored SubcommandHelpShowsLongForm to
UseLongFormatForHelpSubcommand.
Tests and docuemntation examples use about and long_about instead of
(before/after)_help.
Removed commented out tests
Linting: Fix trailing new line
Updated change log, refactored tests and doc str
Reordered items in the Changelog
New test added and old tests removed that were redundant
Doc string for AppSettings::UseLongFormatForHelpSubcommand fixed
* chore: disables mention-bots finding reviewers and pinging tons of people
* docs(README.md): added a warning about using ~ deps
* chore: increase version
* tests: adds tests for default values triggering conditional requirements
* fix: fixes a bug where default values should have triggered a conditional requirement but didnt
Closes#831
* tests: adds tests for missing conditional requirements in usage string of errors
* fix: fixes a bug where conditionally required args werent appearing in errors
* tests: adds tests for completion generators
* tests: adds tests for completions with binaries names that have underscores
* fix: fixes a bug where ZSH completions would panic if the binary name had an underscore in it
Closes#581
* fix: fixes bash completions for commands that have an underscore in the name
Closes#581
* chore: fix the category for crates.io
* docs(Macros): adds a warning about changing values in Cargo.toml not triggering a rebuild automatically
Closes#838
* fix(Completions): fixes a bug where global args weren't included in the generated completion scripts
Closes#841
* fix: fixes a println->debugln typo
* chore: increase version
* fix: fixes a critical bug where subcommand settings were being propogated too far
Closes#832
* imp: adds ArgGroup::multiple to the supported YAML fields for building ArgGroups from YAML
Closes#840
* chore: increase version
* 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
Closes#633
* chore: clippy run
* style: changes debug header to match other Rust projects
* chore: increase version
