Added a new Template.PrintErrors() function call,
used in hugolib/site.go#Process() so it does not clutter
up `go test -v ./...` results.
Special thanks to @tatsushid for mapping out the call trace
which makes it a lot easier to find the appropriate places
to place the Template.PrintErrors() call.
Fixes#316
The variable scope in the Go templates makes it hard, if possible at all, to write templates with counter variables or similar state.
This commit fixes that by adding a writable context to Node, backed by a map: Scratch.
This context has three methods, Get, Set and Add. The Add is tailored for counter variables, but can be used for any built-in numeric values or strings.
Use `{{ if not .Date.IsZero }}` to print dates only when they are
defined. This is to avoid things like
<lastBuildDate>Mon, 01 Jan 0001 00:00:00 +0000</lastBuildDate>
and
<lastmod>0001-01-01T00:00:00+00:00</lastmod>
showing up in index.xml (RSS) and sitemap.xml.
Pipe dates with ±hh:mm time zone through `safeHtml`
to prevent the `+` sign from turning into `+`.
Also make some shuffling to avoid blank lines in the output.
The paths were seen as changed but not static because of the backslashes in
ev.Name. Once the backslashes were added, I discovered that the JSON
sent to livereload was invalid and failed to work because it had backslashes.
Hence the code to replace the backslashes from the path to make them work
in JSON and for the URL.
With this fix, changes to a stylesheet are shown on the page, and if it's a
single file that changed, it's reflected in the browser without reloading the whole
page.
* Add meta author, description and generator tags
* Add Hugo version beside the logo and in the footer
* Suggest the user to run `go get -u -v` to update dependencies
* Requires Go 1.3+ rather than Go 1.1+
* Improve rendering/formatting in some places
* Add trailing slash to URLs where appropriate
* GitHub redirects all http requests to https, update accordingly
On Windows the binary name is hugo.exe and running hugo version results in
this error:
GetFileAttributesEx D:\Dev\Go\gopath\bin\hugo: The system cannot find the file specified.
This fixes that error and allows the binary name to be something other
than hugo on any OS.
Two new configuration properties, `Paginate` (default `0`) and `PaginatePath` (default `page`) are added.
Setting `paginate` to a positive value will split the list pages for the home page, sections and taxonomies into chunks of size of the `paginate` property.
A `.Paginator` is provided to help building a pager menu.
There are two ways to configure a `.Paginator`:
1. The simplest way is just to call `.Paginator.Pages` from a template. It will contain the pages for "that page" (`.Data.Pages` will (like today) contain all the pages).
2. Select a sub-set of the pages with the available template functions and pass the slice to `.Paginate` : `{{ range (.Paginate (where .Data.Pages "Type" "post")).Pages }}`
**NOTE:** For a given Node, it's one of the options above. It's perfectly legitimate to iterate over the same pager more than once, but it's static and cannot change.
The `.Paginator` contains enough information to build a full-blown paginator interface.
The pages are built on the form (note: BLANK means no value, i.e. home page):
```
[SECTION/TAXONOMY/BLANK]/index.html
[SECTION/TAXONOMY/BLANK]/page/1/index.html => redirect to [SECTION/TAXONOMY/BLANK]/index.html
[SECTION/TAXONOMY/BLANK]/page/2/index.html
....
```
