Returns true if a given field value that is a slice / array of strings, integers or floats contains elements in common with the matching value. It follows the same rules as the intersect function.
Closes#1945
While sorting on data sources with missing fields, a panic can occur in
pairList.Less if `Interface()` is called on a invalid `reflect.Value`.
This commit detects an invalid Value and replacing it with a zero value
for the comparison.
This also includes a refactor of the hugofs package and its usage.
The motivation for that is:
The Afero filesystems are brilliant. Hugo's way of adding a dozen of global variables for the different filesystems was a mistake. In readFile (and also in some other places in Hugo today) we need a way to restrict the access inside the working dir. We could use ioutil.ReadFile and implement the path checking, checking the base path and the dots ("..") etc. But it is obviously better to use an Afero BasePathFs combined witha ReadOnlyFs. We could create a use-once-filesystem and handle the initialization ourselves, but since this is also useful to others and the initialization depends on some other global state (which would mean to create a new file system on every invocation), we might as well do it properly and encapsulate the predefined set of filesystems. This change also leads the way, if needed, to encapsulate the file systems in a struct, making it possible to have several file system sets in action at once (parallel multilanguage site building? With Moore's law and all...)
Fixes#1551
To strip away any HTML. May be useful for the .Title in head etc.
People may shoot themself in the foot with this, maybe ...
The replacement function is pretty fast.
The `intersect` function uses `in` to avoid adding duplicates to the
resulting set. We were passing `reflect.Value` items when we should
have been using `Value.Interface()` to send the actual data structure.
This fixes that.
See #1952
This uses the Emoji map from https://github.com/kyokomi/emoji -- but with a custom replacement implementation.
The built-in are fine for most use cases, but in Hugo we do care about pure speed.
The benchmarks below are skewed in Hugo's direction as the source and result is a byte slice,
Kyokomi's implementation works best with strings.
Curious: The easy-to-use `strings.Replacer` is also plenty fast.

Fixes#1891
This commit adds a custom index template function that deviates from the stdlib
simply by not returning an "index out of range" error if an array, slice or
string index is out of range. Instead, we just return nil values. This should
help make the new default function more useful for Hugo users.
Fixes#1949
This commit fixes a few things:
1. `given` is now a variadic parameter so that piping works properly
2. add separate template tests to make sure piping works
3. support time values
4. add more tests of the dfault function
The common is the `where` func and this:
```
panic: reflect: call of reflect.Value.Type on zero Value [recovered]
panic: reflect: call of reflect.Value.Type on zero Value
```
There is no good reason to export all the template funcs:
* They're not used outside the templates.
* If usable in other packages, they should be moved (to helpers?)
* They create too broad an interface;
users of the tpl package don't see the forest for all the trees.
Add humanize (inflect.Humanize) to the template funcMap. Documentation and
tests are included.
Various code cleanups of the template funcs:
- Break pluralize and singularize out into stand-alone funcs.
- Sort the list of funcMap entries.
- Add some minimal godoc comments to all public funcs.
- Fix some issues found by golint and grind.
This fixes a exported field check condition in a way described at Go
issue https://golang.org/issue/12367
According to the issue comments, this fix should be safe under Go 1.6.
`where` template function's internal condition check function doesn't
check boolean values and always returns `false` silently.
This adds missing boolean value comparison to the function.
`where Values ".Param.key" true` like clause can be used.
Only "=", "==", "eq", "!=", "<>", "ne" operators are allowed to be used
with a boolean value. If an other operator is passed with it, the
condition check function returns `false` like before.
'sort' template function used to accept only each element's struct field
name, method name and map key name as its second argument. This extends
it to accept a field/method/key chaining key string like
'Params.foo.bar' as the argument. It evaluates sub elements of each
array or map elements and sorts by them.
Typical use case would be sorting pages by user defined front matter
value. For example, sorting pages by 'Params.foo.bar' is possible by
writing the following template code
{{ range sort .Data.Pages "Params.foo.bar" }}
{{ .Content }}
{{ end }}
It ignores all leading and trailing dots so "Params.foo.bar" can be
written in ".Params.foo.bar"
This also fixes the issue that 'sort' cannot evaluate a pointer value.
Fix#1330
sort template function returns `[]interface{}` type slice value
regardless of its original element type.
This fixes it to keep the original element type. For example, if it
sorts `map[string]int` type value, it returns `[]int` slice value
instead of `[]interface{}` slice value.
`where` template function's internal condition check function always
returns `false` when a target value doesn't exist or it's nil value but
this behavior makes it difficult to filter values which doesn't have a
particular parameter.
To solve it, this adds nil value comparison to the function.
`where Values ".Param.key" nil` like clause can be used for the case
above.
Only "=", "==", "eq", "!=", "<>", "ne" operators are allowed to be used
with `nil`. If an other operator is passed with `nil`, the condition
check function returns `false` like before.
Fix#1232
Where `first` will return the first N items of a rangeable list,
`after` will return all items after the Nth item.
This allows the user to do something with the first N items and
something different with the remaining items after N.
`substr` template function takes one or two range arguments. Both
arguments must be int type values but if it is used with a calclation
function e.g. `add`, `len` etc, it causes a wrong type error.
This fixes the issue to allow the function to take other integer type
variant like `int64` etc.
This also includes a small fix on no range argument case.
Fix#1190
`where` tpl function doesn't support `time.Time` type so if people want
to compare such values, it's required that these values are converted
into `int` and compare them.
This improves it. If `time.Time` values are passed to `where`, it
converts them into `int` internally, compares them and returns the
result.

Many minor fixes to make test logs more consistent and correct a
mispelling.
Standardize on "[%i] got X but expected Y" for log messages. Using
a consistent layout makes it easier to read the test results. This
was mostly changing "Got" to "got". Swapped the order of values on
several calls to bring them in line with the convention.
A few log messages had a sequence number added to identify the
exact scenario that failed. Otherwise, there would be no way to
ascertain which failed When there are many scenarios.
Correct spelling of "expected."

[close#1040]
The previous implementation didn't easily support the use case "I want one base template for the single pages, another for the rest".
The new lookup order is:
1. <current-path>/<template-name>-baseof.ace, e.g. list-baseof.ace
2. <current-path>/baseof.ace
3. _default/<template-name>-baseof.ace, e.g. list-baseof.ace.
4. _default/baseof.ace
As views looks like a regular template, but doesn't need a base template, we have to look inside it.
Altough really not needed by this commit, reading the full file content into memory just to do a substring search is a waste.
So this commit implements a `ReaderContains` func that in most cases should be much faster than doing an `ioutil.ReadAll` and `bytes.Contains`:
```
benchmark old ns/op new ns/op delta
BenchmarkReaderContains 78452 20260 -74.18%
benchmark old allocs new allocs delta
BenchmarkReaderContains 46 20 -56.52%
benchmark old bytes new bytes delta
BenchmarkReaderContains 46496 1258 -97.29%
```
