The lektor static file content management system

Lektor

Lektor is a static website generator. It builds out an entire project from static files into many individual HTML pages and has a built-in admin UI and minimal desktop app.

To see how it works look at the top-level example/ folder, which contains a showcase of the wide variety of Lektor's features.

For a more complete example look at the lektor/lektor-website repository, which contains the sourcecode for the official lektor website.

How do I use this?

For installation instructions head to the official documentation:

• Installation
• Quickstart

Want to develop on Lektor?

This gets you started (assuming you have Python, pip, npm, and pre-commit installed):

$ git clone https://github.com/lektor/lektor
$ cd lektor
$ python -m venv _venv
$ . _venv/bin/activate

# pip>=21.3 is required for PEP 610 support
$ pip install -U "pip>=21.3"

$ pip install --editable .

# If you plan on committing:
$ pre-commit install

# Run the Lektor server
$ export LEKTOR_DEV=1
$ cp -r example example-project
$ lektor --project example-project server

If you want to run the test suite (you'll need tox installed):

$ tox

lektor's Issues

Friendly Markdown

Markdown is nice, but it's not so easy for nontechnical editors that Lektor caters to.

Embedding ProseMirror could help with this problem:

Say you have a site that allows users to enter comments, and you've decided to use Markdown for the comment input. Your target group mostly knows how to use Markdown, and finds it convenient to type. But you also have some non-technical users, for whom learning arcane syntactic rules does not come naturally.

Without changing anything in your backend, you can drop in ProseMirror as an alternative input editor. People can even switch between both views as they are editing!

http://prosemirror.net/demo_markdown.html

I hope someone will like this idea so much that I won't need to do it myself :)

Development environment setup

This continues the discussion from issue #59 with regards to the Admin UI and Webpack file watching.

request: direct link to some paginated page

for example

<a href="{{ this.pagination.url_to(1) }}">First Page</a><!-- /blog/page/1/ -->
<a href="{{ this.pagination.url_to(-1) }}">Last Page</a> <!-- /blog/page/20/ -->
<a href="{{ this.pagination.url_to(999999999999) }}">Non-existed Page - raise error</a>
<a href="{{ this.pagination.url_to('a') }}">wrong type - raise error</a>

more complexly

<a href="{{ site.query('/another_paginated_page').pagination.url_to(10) }}">/another_paginated_page/page/2/</a>
<!-- not good example. -->

Source Code Syntax Highlighting

I see that you highlight syntax in the documentation for lektor. I have copied a chunk of a template from the documentation to a blog page on a test site that I created for evaluating lektor and the same text does not get highlighted.

How can syntax highlighting be enabled on lektor?

Story for SVG Files

Currently svg files are not images largely because we did not want thumbnailing for them. If we add them to the images list we need to find a story for width/height etc.

request: exclude some files from pagination

If I have these(see below) structure and add sitemap with this guide, my list must include sitemap.xml.

• content/contents.lr

_model: blog

• models/blog.ini

[model]
name = Blog
label = Blog
hidden = yes

[children]
model = blog-post
order_by = -pub_date, title
slug_format = {{ this.pub_date|dateformat('YYYY-MM-dd') }}/{{ this.title }}/

[pagination]
enabled = yes
per_page = 1

How can I pop sitemap.xml or some files (like keybase proof) from pagination? (Currently I make simple sitemap build package to avoid this problem)

Relative link on markdown field does not resolved correclty

When I put ![An image](./an-image.png) on /blog/post-1, the image shows correctly on /blog/post-1. The content of post-1 is also listed on /blog, but the image is also linked to /blog/an-image.png not /blog/post-1/an-image.png.

The temporary solution at them moment is to use absolute links.

Better position for `Save Changes` Button

Button should always be visible in the admin UI, no matter how long the page is.

generate incorrect file name

• /content/test.xml/contents.lr

_template: test.html

---
_model: none

• /models/none.ini
  → empty
• template/test.html

hello world

• log

U index.html
U page/2/index.html
U page/3/index.html
U page/4/index.html
U 2015-12-21/Hello_Website/index.html
U 2015-12-21/Hello_Website1/index.html
U 2015-12-21/Hello_Website3/index.html
U temp-test.xml

I want to get test.xml but got temp-test.xml. How to remove it?

Document Pagination.iter_page

• Remove non-exists function in python docstring (use Pagination.for_page and url instead of url_for)
• Add to Docs

Give user a cue for date format in blog post create/edit

As an enhancement, giving the user a visual cue of the date format to be entered would be helpful. It took me a while to find default format in api docs. I also tried clicking on the mini-calendar thinking it would pop up a date picker.

Overall, a very cool project ☀️

Plugin development for Lektor

[This is probably a question, not a bug. But creating the new tag lektor on stack overflow requires 1500 reputation, which I do not have as I do not use it. So I am putting this here]

I am trying to develop a reStructuredText plugin and doing some basic mistake.

My plugin object looks like this:

    class RSTPlugin(Plugin):
        name = 'RST'
        description = 'RST plugin'

        def on_setup_env(self, **extra):
            self.env.jinja_env.filters['markdown'] = \
                jinja2.contextfilter(lambda ctx, *a, **kw: RST(*a, **kw))

Now: the on_setup_env function is called. Notice that I am replacing the markdown dict entry (for now). But when I run lektor the original Markdown class is called and not my RST one.

I suspect I am doing something ridiculous here, but cannot find the problem... This might be a bug in lektor, but I suspect is more a bug in my head...

The error UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-6 seems to be a problem of PyYAML.

I wish I could view the content of c:\users\lyenliang\appdata\local\temp\pip-build-qxh26z\PyYAML\setup.py, but the file doesn't exist after the installation script.

Does anyone have an idea about how to solve this problem?

Templates: relative links to alternatives doesn't work if _slug is set

Using {{ '.'|url(alt='ru') }} as per https://www.getlektor.com/docs/templates/urls/ doesn't work correctly if a _slug was set in the contents+ALT.lr file.

For example:

1. page /about with alternatives en (primary) and de.
2. contents+de.lr has _slug=/bio.
3. The link generated for {{ '.'|url(alt='de') }}is incorrectly /de/about/bio instead of /de/bio.

Workaround for now is to use {{ this._path|url(alt='de') }} instead of the relative link.

Getting "not configured for a valid publishing method" with sftp deployment target

Hey there,

Was trying to have a go at doing a test deployment via sftp.
When I try through the admin gui, it fails silently with no feedback.
In fact, it says Status: publishing done.

I checked the server to see if the files were actually transferred, but no go.
So next I tried the cli:

lektor deploy production

And got this message:

Usage: lektor deploy [OPTIONS] [SERVER]

Error: Server "production" is not configured for a valid publishing method.

After some fiddling, I noticed that if I switched the url scheme to ftp:// instead of sftp://, it was recognized as a valid target for lektor deploy, but the actual deploy failed because the server is setup to only accept sftp connections.

Any ideas where I can go snooping around the code to look for a root cause?

Thanks.

A file deleted and re-created won't be built

I created a quickstart project, deleted the layout.html and re-created it, but it wasn't taken into account by the build system any more. In the browser, I simply had "TemplateNotFound: layout.html".

I had to delete the cached build.

I was expecting the file to be rebuilt so I think that's a bug :]

(note: I noticed something similar when I comment and uncomment comments in some html, which can lead to remaining problems if this breaks jinja tags).

Document _undiscoverable

The new system field _undiscoverable needs documentation. This also added these new APIs:

• Query.include_undiscoverable
• SourceObject.is_discoverable
• SourceObject.is_undiscoverable

In addition it changed is_hidden a bit so the text should probably be reviewed for .children and other APIs.

Lektor Quickstart
=================

This wizard will generate a new basic project with some sensible defaults for
getting started quickly.  We jsut need to go through a few questions so that
the project is set up correctly for you.

Step 1:
| A project needs a name.  The name is primarily used for the admin UI and
| some other places to refer to your project to not get confused if multiple
| projects exist.  You can change this at any later point.
> Project Name: kk

Step 2:
| This is the path where the project will be located.  You can move a
| project around later if you do not like the path.  If you provide a
| relative path it will be relative to the working directory.
> Project Path [/home/ozn/Software/p/kk]: 

Step 3:
| Do you want to generate a basic blog module?  If you enable this the
| models for a very basic blog will be generated.
> Add Basic Blog [Y/n]: 

Step 4:
| Your name.  This is used in a few places in the default template to refer
| to in the default copyright messages.
> Author Name [ozn]: 

That's all. Create project? [Y/n]

Question: How to turn on syntax highlight?

Lektor official site use syntax highlight but I can not find this option from docs.

How can I use syntax highlight?

url generation does not work from virtual sources

I'm editing lektor.com's sources, adding alternatives. In layout.html:

<a href="{{'.'|url(alt='es')}}

but that leads to a cryptic error message on build:

E blog/archives/index.html (AttributeError: 'NoneType' object has no attribute 'endswith')

When we go to blog/archives/index.html we get the stacktrace:

Thumbnails not copied correctly

I think my attachment thumbnails are not copied at all.

models/project.ini:

[model]
name = Project
label = {{ this.name }}

[fields.cover]
label = Cover
type = select
source = record.attachments.images

templates/project.html:

{% for project in site.query('/projects') %}
  <img src="{{ project.attachments.images.get(project.cover).thumbnail(263)|url }}">
{% endfor %

Rendered html:

<img src="./projects/my-project/[email protected]">

Error at lektor build -v (more debug don't give more information):

U projects/my-project/[e-mail]
  E projects/my-project/[e-mail] (TypeError: argument of type 'NoneType' is not iterable)

Lektor version: 1.0

Empty slug not handled correctly.

Having an empty slug, breaks ftp deploy (maybe also other deployment methods):

$cat document.pdf.lr 
_slug:

To reproduce on the admin interface:

1. edit a slug
2. remove the content of the textfield again
3. save
4. deployment broken (see backtrace)

I saw this issue on a document attachment, but maybe it is more general. I'll dig in a bit deeper if I have some time. I suspect somewhere there is a check "if var is not None" that should be "if var".

Files with edits after first 4k are not elected for FTP upload.

When creating a one-page site, updates "mysteriously" stopped working. After a bit of digging, I saw in lektor/publisher.py:407 that only the first 4k is hashed to check if an update is needed. As my changes are past this boundary, the file is never uploaded.

The most obvious fix would be to hash the entire file, but I guess the original idea was to avoid hashing very large files.

Document Pagination.for_page

New feature in 2.0 that needs documentation.

Mac App can't install shell command

Mac App gui - no way to create a project

The mac app initial gui has open project but not create new project.

Admin preview of root page does not always work in Firefox

This was tested on the lektor/lektor-website repository.

Ways I've discovered to reproduce this:

1. Navigate directly to localhost/admin/root/preview, or
2. Edit the root page, and then press save changes

How to get the root preview to work:
While previewing a subpage, click the index link in the top-left of the admin. The root preview now works. However, performing either action above breaks it again.

Related question: How do you set up development for working on the react admin interface? I tried LEKTOR_DEV=1 lektor server -f webpack but I seem to need to re-run that command every time I change a file :/

Re-Design Flow Format

The current serialization of the flow format is pretty terrible. Originally the idea was to avoid indentation based syntax for it but I'm not sure if that's a good idea. Now would be the time to fix it, so maybe people have some suggestions.

Potential idea:

my_flow_field:
  flow_block_model:
    field1: value1
    ---
    field 2:

    value 2
  flow_block_model_2:
    field1: value1
    ---
    field 2:

Story on PIP Cache

Our preferred installation is a hidden pip install via curl|sh. This sets up a virtualenv in a path and a lot of stuff is managed automatically within it. This should later also support lektor upgrade and lektor uninstall or something along those lines.

For now however we have a problem where we use the system pip cache instead of a cache within this virtualenv. This is problematic for a few reasons:

• people that do not know about pip will be confused that we throw crap into ~/.pip
• we get permissions wrong if people sudo install something
• both lektor and plugin installation change depending on if stuff is cached or not but it's hard to tell for users.

What we should do is to set up a pip cache in venv/cache and then add commands to lektor to manage this cache somehow. Also upon uninstallation we should wipe all caches that are set up.

Add datetime type and timezone support

I can use date type but it can not save time info.

Please add datetime type

Known Issue:

• timezone?

Add Expiry Support

For many situations it would be very nice if a plugin or the page itself can set up an expiry that will mark the sources dirty after a certain amount of time passed. This is for instance very useful if data is pulled in via an HTTP request.

Make Lektor's GUI generator agnostic?

More a feature request/discussion: how hard is it to use the GUI on top of another static website generator?

I'm guessing that a lot of people already have their own generators in place but would be very happy with the admin to ease the file generation :).

get_doc_link for the toc: once points to the good alternative page, once not.

Hey,

I copied the sources of getlektor.com and added some alternatives, in order to build a multilingual website. My problem is that the urls of the toc menu on the left always point to the default alternative, consequently with their title in the wrong language too, when the ones at the bottom of the page work correctly. The get_doc_link macro is working for the bottom of the page, is it not working for the left menu ? How can we achieve that ?

in templates/doc-page.html this macro is called once to build the toc on the left: (so the urls only go to the default alternative andt the titles are of the wrong language)

        {% set docs = site.get('/docs') %}
        {% for child in set.get('docs').children recursive %}
          <li{% if this._path == child._path %} class="active"{% endif
              %}>{{ get_doc_link(child) }}
            {% if this.is_child_of(child) %}
            <ul>{{ loop(child.children) }}</ul>
            {% endif %}
        {% endfor %}

and again when building the two-columns links at the bottom:

        {% for cols in this.children|batch(2) %}
          <div class="row">
            {% for page in cols if page %}
            <div class="col-md-6 child">
              <h4>
                {{ get_doc_icon(page) }}
                {{ get_doc_link(page) }}
              </h4>
              {% if page.summary %}
                <p class="summary">{{ page.summary }}</p>
              {% endif %}
            </div>
            {% endfor %}
          </div>
        {% endfor %}

In Website.lektorproject I defined those alternatives:

[alternatives.fr]
primary = yes
name = French
locale = fr

[alternatives.en]
name = English
locale = en_US
url_prefix = /en/

[alternatives.es]
name = Castellano
locale = es_ES
url_prefix = /es/

I tried to modify the environment before the first call, with no success.

I'm using pypi's latest (v1.0). I can point to a live example if you wish.

Thanks !

Allow URL field type to contain relative URLs?

Wondering what your thoughts were on this before having a go at implementing.

install script under virtualenv picks bad binary paths

The default script with fail when the default python is version 3.

I have started working on a version that is python agnostic (attached). But this still seems to fail when using a python distribution like anacoda, for example is installs binaries on
/home/USER/.local/
without consideration for the local environment,

install.zip

pip install works fine, BTW

document body.toc, sort_key

In getlektor.com sources, I see that the menu of the left, representing the toc of the documentation, is built with a few tricks:

      {% if this.body.toc %}

and a search of all pages, where I guess the sort_key data in a content.lr file is responsible for the ordering

title: Quickstart

---
summary: Covers how to create a very basic website project with Lektor and run it.

---
sort_key: 60

---
body:

in doc-page.html:

    {% for child in docs.children recursive %}
      <li{% if this._path == child._path %} class="active"{% endif
          %}>{{ get_doc_link(child) }}
        {% if this.is_child_of(child) %}
        <ul>{{ loop(child.children) }}</ul>
        {% endif %}
    {% endfor %}

Are sort_key, this._path, doc.children, this.body.toc all jinja features ? If not, more doc is welcome, or that's an idea for a next blog post :)

thanks !

Document Publisher API

Right now providing publishers through plugins is not supported but #25 is introducing that. So this needs documentation and a sanity check on the API.

Dev server cannot serve pagination for pages > 1

• used command

$ lektor server -f webpack

I think it is bug of test server
