Add an additional test to "Variant 4, theme, use site base" to also test
for the index.html base (from by testing of #3505). Also add a "name"
field to the test cases to make it easier to know which test is failing
versus just getting a slice index.
* Adds retro-coverage for #4361
* Verifies open issues #4138, #3890, #4366, 4083
* Removes test reliance on the very code it is testing (hugo/parser package).
Expected results are now all built manually / are more precise.
Tests can run against different versions (no linkage errs)
This fixes some issues with language params handling by separating params from configuration values per language.
This means that you can now do this:
```toml
[languages]
[languages.en]
languageName = "English"
weight = 1
title = "My Cool Site"
[languages.en.params]
myParam = "Hi!"
```
This is not a breaking change, but the above is a less suprising way of configuring custom params.
It also fixes some hard-to-debug corner-cases in multilingual sites.
Fixes#4356Fixes#4352
This commit adds a new config setting:
```toml
disableLanguages = ["fr"]
```
If this is a multilingual site:
* No site for the French language will be created
* French content pages will be ignored/not read
* The French language configuration (menus etc.) will also be ignored
This makes it possible to start translating new languages and turn it on when you're happy etc.
Fixes#4297Fixed#4329
* Page without front matter now treated same as a page with empty front matter.
* Test cases added to cover this and repro issue #4320.
* Type safety of front matter code improved.
Fixes#4320
Now, even for nun-bundles it is possible to do lookup without path or extension.
So, given `blog/my-blog-post.en.md` these lookups will succeed:
* `blog/my-blog-post.en.md`
* `blog/my-blog-post`
* `my-blog-post.en.md`
* `my-blog-post`
See #4312
See https://github.com/gohugoio/hugoDocs/issues/307
Given a bundle in `blog/my-bundle/index.en.md` all of these will now worK:
* `blog/my-bundle/index.en.md`
* `blog/my-bundle/index`
* `blog/my-bundle`
* `my-bundle`
The last one is potentially ambigous.
Fixes#4312
This commit adds support for `headless bundles` for the `index` bundle type.
So:
```toml
headless = true
```
In front matter means that
* It will have no `Permalink` and no rendered HTML in /public
* It will not be part of `.Site.RegularPages` etc.
But you can get it by:
* `.Site.GetPage ...`
The use cases are many:
* Shared media galleries
* Reusable page content "snippets"
* ...
Fixes#4311
You can still use the full path with extensions, but to get the current language version:
* If the content file lives in `/content/blog/mypost.en.md`
* Use `.Site.GetPage "page" "blog/mypost"`
Fixes#4285
This commit expands the Resource interface with 3 new methods:
* Name
* Title
* Params
All of these can be set in the Page front matter. `Name` will get its default value from the base filename, and is the value used in the ByPrefix and GetByPrefix lookup methods.
Fixes#4244
This commit also has some other nice side-effects:
* The layout logic is unified for all page types, which should make it less surprising
* Page.Render now supports all types
* The legacy "indexes" type is removed from the template lookup order. This is an undocumented type from early Hugo days. This means that having a template in, say, `/layouts/indexes/list.html` will no longer work.
* The theme override logic is improved. As an example, an `index.html` in theme will now wn over a `_default/list.html` in the project, which most will expect.
Fixes#3005Fixes#3245
* We match by path vs taxonomy to determine if we have a content page for that taxonomy
* The taxonomy name is (if `preserveTaxonomyNames` is not set) normalized to `maxmustermann` while you have the disk folder called `MaxMustermann`.
* This isn't a new issue, but I suspect most people will just name the folder `authors/maxmustermann` and it will just work.
* The inconsistent behaviour you see here is that you will end up with two pages with the same target filename, so it is a little random who will win.
This fixes that by also normalizing the taxonomy path when doing the comparison.
Fixes#4238
We still do lowering of the param strings in some internal use of this, but the exported `GetParam` method is changed to a more sensible default.
This was used for the `disqus_title` etc. in the internal Disqus template, which was obviously not right.
If you really want to lowercase your params, do it with `.GetParam "myparam" | lower` or similar.
Fixes#4187
This commit is not the smallest in Hugo's history.
Some hightlights include:
* Page bundles (for complete articles, keeping images and content together etc.).
* Bundled images can be processed in as many versions/sizes as you need with the three methods `Resize`, `Fill` and `Fit`.
* Processed images are cached inside `resources/_gen/images` (default) in your project.
* Symbolic links (both files and dirs) are now allowed anywhere inside /content
* A new table based build summary
* The "Total in nn ms" now reports the total including the handling of the files inside /static. So if it now reports more than you're used to, it is just **more real** and probably faster than before (see below).
A site building benchmark run compared to `v0.31.1` shows that this should be slightly faster and use less memory:

Recognize the Pandoc format under the file extension .pandoc or .pdc,
and shell out to pandoc as an external helper to format Pandoc content.
Refactor out repeated code with external helpers. Change the error
output formatting. I did not see any of the external helpers print the
string "<input>" to represent stdin as a file; just prepending the file
name to error output is more general and doesn't sacrifice that much in
terms of readability.
Closes#234
This commit refines the key used to map translations:
* Use `translationKey` set in front matter
* Fall back to path + base filename (i.e. the filename without extension and language code)
Note that the Page Kinde will be prepended to both cases above. It does not make sense to have a section as translation for the home page.
Fixes#2699
This commit adds support for multiple statDirs both on the global and language level.
A simple `config.toml` example:
```bash
staticDir = ["static1", "static2"]
[languages]
[languages.no]
staticDir = ["staticDir_override", "static_no"]
baseURL = "https://example.no"
languageName = "Norsk"
weight = 1
title = "På norsk"
[languages.en]
staticDir2 = "static_en"
baseURL = "https://example.com"
languageName = "English"
weight = 2
title = "In English"
```
In the above, with no theme used:
the English site will get its static files as a union of "static1", "static2" and "static_en". On file duplicates, the right-most version will win.
the Norwegian site will get its static files as a union of "staticDir_override" and "static_no".
This commit also concludes the Multihost support in #4027.
Fixes#36Closes#4027
Return the correct virtual Section for Taxonomy and TaxonomyTerm.
Restrict permalink expansion to only Pages and Taxonomies, but then
actually use expanded permalinks even for non-Pages.
Fixes#1208.
Hugo already, in its server mode, support partial rebuilds. To put it simply: If you change `about.md`, only that content page is read and processed, then Hugo does some processing (taxonomies etc.) and the full site is rendered.
This commit covers the rendering part: We now only re-render the pages you work on, i.e. the last n pages you watched in the browser (which obviously also includes the page in the example above).
To be more specific: When you are running the hugo server in watch (aka. livereload) mode, and change a template or a content file, then we do a partial re-rendering of the following:
* The current content page (if it is a content change)
* The home page
* Up to the last 10 pages you visited on the site.
This should in most cases be enough, but if you navigate to something completely different, you may see stale content. Doing an edit will then refresh that page.
Note that this feature is enabled by default. To turn it off, run `hugo server --disableFastRender`.
Fixes#3962
See #1643
Changes fall into one of the following:
- gofmt -s
- receiver name is inconsistent
- omit unused 2nd value from range
- godoc comment formed incorrectly
- err assigned and not used
- if block ends with a return statement followed by else
Move SummaryLength into the ContentSpec struct and refactor the
relevant summary functions to be methods of ContentSpec. The new
summaryLength struct member is configurable by the summaryLength config
value, and the default remains 70. Also updates hugolib/page to use the
refactored methods.

This makes live reloading behind a HTTPS proxy working, as in the example below using the service from https://ngrok.com:
```

Also related:
* support "modified" as an optional way to signal "last modified"
* make sure all relevant page dates are also added to params
Fixes#3867
This closes#98, even if this commit does not do full content text search.
We may revisit that problem in the future, but that deserves its own issue.
Fixes#98
And use it in `eq` and `ne` so `Page` values can be compared directly in the templates without thinking about it being a `Page` or a `PageOutput` wrapper.
Fixes#3807
As pointed out by the linter, some exported functions and types are
missing doc comments.
The linter warnings have been reduced from 194 to 116.
Not all missing comments have been added in this commit though.
This works for the `title` func and the other places where Hugo makes title case.
* AP style (new default)
* Chicago style
* Go style (what we have today)
Fixes#989
Why:
* first time using hugo I got very little info from --verbose output
but I noticed there is quite a lot of useful DEBUG logging
* asked for in other issues like https://github.com/gohugoio/hugo/issues/3514
This change addreses the need by:
* adding a simple --debug flag which simply turns on debug level in stdout
and logoutput if enabled.
This applies to both regular templates and shortcodes. So, if the site language is French and the output format is AMP, this is the (start) of the lookup order for the home page:
1. index.fr.amp.html
2. index.amp.html
3. index.fr.html
4. index.html
5. ...
Fixes#3360
This commit adds a new `--navigateToChanged` and config setting with the same name, that, when running the Hugo server with live reload enabled, will navigate to the current content file's URL on save.
This is really useful for site-wide content changes (copyedits etc.).
Fixes#3643
This change is motivated by Netlify's `_redirects` files, which is currently not possible to generate with Hugo.
This commit adds a `Delimiter` field to media type, which defaults to ".", but can be blanked out.
Fixes#3614
Note that even with this setting enabled, the aliases themselves are preserved on the pages.
The big motivation for this change is to be able to use the alias definitions to generate `.htaccess` or Netlify's `_redirect` files with server-side redirects.
Fixes#3613
This commit fixes an issue introduced in the recently released Hugo 0.22.
This logic did not handle the case with root sections with non-section subfolders very well.
Fixes#3586
This enables both the variants below:
Current (first level only):
```
"blog": ":section/:title",
```
Nested (all levels):
```
"blog": ":sections/:title",
```
Should ideally been part of Hugo 0.22, but better late than never ...
Fixes#3580
This issue is more visible now that we support nested sections.
This commit makes operations like pasting new content folders or deleting content folders during server watch just work.
Fixes#3570
We still have go-toml as a transitive dependency, and it is the way to go eventually, but we care about speed, so let us wait that one out.
Note that the issue this fixes is about taxonomies, but I guess this is a general issue for sites with many pages that uses TOML as front matter.

./benchSite.sh "frontmatter=YAML,num_root_sections=1,num_pages=.*,tags_per_page=20,shortcodes=false,render=false"
To run a subset of these benchmark, one can do something like this:
```
go test -run="NONE" -bench="BenchmarkSiteBuilding/tags_per_page=0.*shortcodes=true.*render=false" -test.benchmem=true ./hugolib
```
Which will run without any tags, with shortcodes, but will skip rendering.

A common use case for this is to redefine the built-in output format `RSS` to give it a different URL.
Before this commit, that was not possible without also providing an `outputs` definition.
Fixes#3447
This commit allows shortcode per output format, a typical use case would be the special AMP media tags.
Note that this will only re-render the "overridden" shortcodes and only in pages where these are used, so performance in the normal case should not suffer.
Closes#3220
This commit moves almost all of the template functions into separate
packages under tpl/ and adds a namespace framework. All changes should
be backward compatible for end users, as all existing function names in
the template funcMap are left intact.
Seq and DoArithmatic have been moved out of the helpers package and into
template namespaces.
Most of the tests involved have been refactored, and many new tests have
been written. There's still work to do, but this is a big improvement.
I got a little overzealous and added some new functions along the way:
- strings.Contains
- strings.ContainsAny
- strings.HasSuffix
- strings.TrimPrefix
- strings.TrimSuffix
Documentation is forthcoming.
Fixes#3042
Hugo 0.20 broke some sites that grouped their blog post and images together in subfolders.
This commit re-introduces that behaviour:
* If the file base name resolves to the same as the base name for the output type (i.e. "index" for HTML), the user probably meant it, so we treat that as an `uglyURL`, i.e. `my-blog-post-1.md`=> `/my-blog-post-1/index.html`
* The main use case for this is to group blog post and images together.
* Note that for the top level folder there will be a potential name conflict with a `section` `index.html` (if enabled)
* This issue will not be relevant for subfolders in sections
* Hugo will soon add support for nested sections, but we will have to find a way to separate them from the rest (`/content/_mysubsection` maybe).
Fixes#3396
This commit adds a work flow aroung GoReleaser to get the Hugo release process automated and more uniform:
* It can be run fully automated or in two steps to allow for manual edits of the relase notes.
* It supports both patch and full releases.
* It fetches author, issue, repo info. etc. for the release notes from GitHub.
* The file names produced are mainly the same as before, but we no use tar.gz as archive for all Unix versions.
* There isn't a fully automated CI setup in place yet, but the release tag is marked in the commit message with "[ci deploy]"
Fixes#3358
Partial rebuild does not have the same logic as normal rebuild on
selecting which file to build. This change makes it possible to
share the file select logic between two kinds of build.
Fix#3325.
This makes it consistent with how it behaves when it's set in config.toml.
This commit also unifies BaseURL in Site.Info so we now have one source for this value.
Fixes#3262
Before this commit, Hugo used `html/template` for all Go templates.
While this is a fine choice for HTML and maybe also RSS feeds, it is painful for plain text formats such as CSV, JSON etc.
This commit fixes that by using the `IsPlainText` attribute on the output format to decide what to use.
A couple of notes:
* The above requires a nonambiguous template name to type mapping. I.e. `/layouts/_default/list.json` will only work if there is only one JSON output format, `/layouts/_default/list.mytype.json` will always work.
* Ambiguous types will fall back to HTML.
* Partials inherits the text vs HTML identificator of the container template. This also means that plain text templates can only include plain text partials.
* Shortcode templates are, by definition, currently HTML templates only.
Fixes#3221
Having the content page name in the log key for the distinct error logger isnt't very usable when you have an error in a commonly used partial.
Using the Page Kind reduces the amount of log entries. Here is an example from an error in the partial menu.html, used in all the page templates:

Using it for list pages doesn't work and has potential weird side-effects.
The user probably meant to range over .Site.ReqularPages, and that is now marked clearly in the log.
Will have to fix this in a better way later in relation to the non-renderable pages.
But this commit brings the Hugo Benchmark down to "only slightly slower" than master.

This is a pretty fundamental change in Hugo, but absolutely needed if we should have any hope of getting "multiple outputs" done.
This commit's goal is to say:
* Every file target path is created by `createTargetPath`, i.e. one function for all.
* That function takes every page and site parameter into account, to avoid fragile string parsing to uglify etc. later on.
* The path creation logic has full test coverage.
* All permalinks, paginator URLs etc. are then built on top of that same logic.

Changing it to PageOutput was a mistake. You may think that the increased parallelism should be a good thing.
But not so much with the increased lock contention and more complex concurrency model.
This commit fixes two different, but related issues:
1) Live-reload when a new shortcode was defined in the content file before the shortcode itself was created.
2) Live-reload when a newly defined shortcode changed its "inner content" status.
This commit also improves the shortcode related error messages to include the full path to the content file in question.

Lots of cleanups here:
- Refactor InterfaceToConfig and InterfaceToFrontMatter to use io.Writer.
- Simplify InterfaceToFrontMatter by wrapping InterfaceToConfig.
- Export FrontmatterType since we return it in DetectFrontMatter.
- Refactor removeTOMLIdentifier to avoid blindly replacing "+++".
- Update HandleJSONMetaData to return an empty map on nil input.
- Updates vendored goorgeous package and test for org-mode frontmatter.
- Add tests and godoc comments.
Coverage for parser package increased from 45.2% to 85.2%.
Previously this was left empty, but it is very handy to have a list
of term pages for a given taxonomy. This list can now be paginated
like other page lists. It makes it possible to render summary
content from each terms index page for instance. It also makes it
possible to sort the term pages in the same way that other page
lists can be sorted. An RSS feed is now generated for
KindTaxonomyTerm pages as well.
This also fixes a bug in HugoSites.createMissingPages. Previously
it would only check for existing KindTaxonomyTerm pages if the
taxonomy had any terms defined. So for a taxonomy with no terms
but a taxonomy terms page it would generate a second empty terms
page.
This relates to #3123.
The interfaces and types in `target` made sense at some point, but now this package is too restricted to a hardcoded set of media types.
The overall current logic:
* Create a file path based on some `Translator` with some hardcoded logic handling uglyURLs, hardcoded html suffix etc.
* In in some cases (alias), a template is applied to create the alias file.
* Then the content is written to destination.
One could argue that it is the last bullet that is the actual core responsibility.
This commit fixes that by moving the `hugolib`-related logic where it belong, and simplify the code, i.e. remove the abstractions.
This code will most certainly evolve once we start on #3123, but now it is at least possible to understand where to start.
Fixes#3123
