Cobra, the CLI commander in use in Hugo, has some long awaited improvements in the error handling department.
This enables a more centralized error handling approach.
This commit introduces that by changing all the command funcs to `RunE`:
* The core part of the error logging, usage logging and `os.Exit(-1)` is now performed in one place and that one place only.
* The usage text is now only shown on invalid arguments etc. (user errors)
Fixes#1502
It would be helpful to know whether a shortcode was called with positional or
named parameters. This commit adds a boolean `IsNamedParams` property to the
`ShortcodeWithPage` struct.
Currently a `[]byte` copy is returned. In most cases this is the safe thing to do, but we should just modify/grow the slice as needed.
This is faster and consumes less memory:
```
benchmark old ns/op new ns/op delta
BenchmarkReplaceShortcodeTokens-4 7350 4419 -39.88%
benchmark old allocs new allocs delta
BenchmarkReplaceShortcodeTokens-4 5 1 -80.00%
benchmark old bytes new bytes delta
BenchmarkReplaceShortcodeTokens-4 4816 1152 -76.08%
```
This commit is aso a small spring cleaning of duplicated code in the different `PageConvert` methods.
Fixes#1516
Page.GroupByParam function internally uses Page.GetParam to get a
parameter value for a key of a page group but now Page.GetParam returns
a lowercase character string every time. It has no need to using
lowercase character string as a group key value and it confuse a
function user.
This fixes it to keep and return an original parameter string as a group
key value.
Fix#1564
* add global `hasCJKLanguage` flag, if true, turn on auto-detecting CJKLanguage
* add `isCJKLanguage` frontmatter to force specify whether is CJKLanguage or not
* For .Summary: If isCJKLanguage is true, use the runes as basis for truncation, else keep as today.
* For WordCount: If isCJKLanguage is true, use the runes as basis for calculation, else keep as today.
* Unexport RuneCount
Fixes#1377
Add validation before creating aliases:
* Prevent creating aliases outside webroot (public/ dir)
* Skip empty "" alias
* Skip "/" → "/index.html", which gets overwritten anyway
* Refuse to create Windows-invalid filenames on Windows;
warn on other platforms
* In case of invalid aliases, after skipping them,
return `err = nil` to prevent the error passing up
all the way to `hugolib.Render()` and causing Hugo to abort.
* Update alias tests.
Fixes#701: Add support for alias with whitespace
Fixes#1418: Add validation for alias
