Add readFile template func 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

Move template library into it's own package (tpl). No longer dependent on hugolib. Can be used externally.

package tpl
Truncated; .Site.Params; First function * Add `.Truncated` bool to each page; will be set true if the `.Summary` is truncated and it's worth showing a "more" link of some kind. * Add `Params` to the site config, defining `.Site.Params` accessible to each page; this lets the site maintainer associate arbitrary data with names, on a site-wide basis. * Provide a `First` function to templates: * Use-case: `{{range First 5 .Site.Recent}}` or anything else which is a simple iterable provided by hugolib * Tests by me for `.Truncated` and `First` Also @noahcampbell contributed towards this: * Add UnitTest for `.Site.Params`: > Digging into this test case a bit more, I'm realizing that we need > to create a param test case to ensure that for each type we render > (page, index, homepage, rss, etc.) that the proper fields are > represented. This will help us refactor without fear in the > future. Sample config.yaml: ```yaml title: "Test site" params: Subtitle: "More tests always good" AuthorName: "John Doe" SidebarRecentLimit: 5 ``` Signed-off-by: Noah Campbell <noahcampbell@gmail.com>
