Once Gemican is installed and you have some content (e.g., in Markdown or Gemtext format), you can convert your content into HTML via the `gemican` command, specifying the path to your content and (optionally) the path to your settings[1] file:
gemican /path/to/your/content/ [-s path/to/your/settings.py]
The above command will generate your site and save it in the `output/` folder, using the default theme to produce a simple site. The default theme consists of very simple Gemtext that supports most of the default settings and is provided so folks may use it as a basis for creating their own themes.
When working on a single article or page, it is possible to generate only the file that corresponds to that content. To do this, use the `--write-selected` argument, like so:
gemican --write-selected output/posts/my-post-title.gmi
Note that you must specify the path to the generated *output* file — not the source content. To determine the output file name and location, use the `--debug` flag. If desired, `--write-selected` can take a comma-separated list of paths or can be configured as a setting.
You can also tell Gemican to watch for your modifications, instead of manually re-running it every time you want to see your changes. To enable this, run the `gemican` command with the `-r` or `--autoreload` option. On non-Windows environments, this option can also be combined with the `-l` or `--listen` option to simultaneously both auto-regenerate *and* serve the output at gemini://localhost:1966[2]:
gemican --autoreload --listen
Gemican has other command-line switches available. Have a look at the help to see all the options you can use:
gemican --help
After you have generated your site, previewed it in your local development environment, and are ready to deploy it to production, you might first re-generate your site with any production-specific settings (e.g., analytics feeds, etc.) that you may have defined:
gemican content -s publishconf.py
To base your publish configuration on top of your `gemicanconf.py`, you can import your `gemicanconf` settings by including the following line in your `publishconf.py`:
from gemicanconf import *
If you have generated a `publishconf.py` using `gemican-quickstart`, this line is included by default.
The steps for deploying your site will depend on where it will be hosted. If you have SSH access to a server running Gemini server software, you might use the `rsync` tool to transmit your site files:
rsync -avc --delete output/ host.example.com:/var/gemini/your-site/
There are many other deployment options, some of which can be configured when first setting up your site via the `gemican-quickstart` command. See the Tips[3] page for detail on publishing via GitHub Pages.
While the `gemican` command is the canonical way to generate your site, automation tools can be used to streamline the generation and publication flow. One of the questions asked during the `gemican-quickstart` process pertains to whether you want to automate site generation and publication. If you answered "yes" to that question, a `tasks.py` and `Makefile` will be generated in the root of your project. These files, pre-populated with certain information gleaned from other answers provided during the `gemican-quickstart` process, are meant as a starting point and should be customized to fit your particular needs and usage patterns. If you find one or both of these automation tools to be of limited utility, these files can deleted at any time and will not affect usage of the canonical `gemican` command.
Following are automation tools that "wrap" the `gemican` command and can simplify the process of generating, previewing, and uploading your site.
The advantage of Invoke[4] is that it is written in Python and thus can be used in a wide range of environments. The downside is that it must be installed separately. Use the following command to install Invoke, prefixing with `sudo` if your environment requires it:
python -m pip install invoke
Take a moment to open the `tasks.py` file that was generated in your project root. You will see a number of commands, any one of which can be renamed, removed, and/or customized to your liking. Using the out-of-the-box configuration, you can generate your site via:
invoke build
If you'd prefer to have Gemican automatically regenerate your site every time a change is detected (which is handy when testing locally), use the following command instead:
invoke regenerate
To serve the generated site so it can be previewed in your browser at gemini://localhost:1966/:
invoke serve
To serve the generated site with automatic browser reloading every time a change is detected, first `python -m pip install livereload`, then use the following command:
invoke livereload
If during the `gemican-quickstart` process you answered "yes" when asked whether you want to upload your site via SSH, you can use the following command to publish your site via rsync over SSH:
invoke publish
These are just a few of the commands available by default, so feel free to explore `tasks.py` and see what other commands are available. More importantly, don't hesitate to customize `tasks.py` to suit your specific needs and preferences.
A `Makefile` is also automatically created for you when you say "yes" to the relevant question during the `gemican-quickstart` process. The advantage of this method is that the `make` command is built into most POSIX systems and thus doesn't require installing anything else in order to use it. The downside is that non-POSIX systems (e.g., Windows) do not include `make`, and installing it on those systems can be a non-trivial task.
If you want to use `make` to generate your site using the settings in `gemicanconf.py`, run:
make gemtext
To generate the site for production, using the settings in `publishconf.py`, run:
make publish
If you'd prefer to have Gemican automatically regenerate your site every time a change is detected (which is handy when testing locally), use the following command instead:
make regenerate
To serve the generated site so it can be previewed in your browser at gemini://localhost:1966/:
make serve
Normally you would need to run `make regenerate` and `make serve` in two separate terminal sessions, but you can run both at once via:
make devserver
The above command will simultaneously run Gemican in regeneration mode as well as serve the output at gemini://localhost:1966.
When you're ready to publish your site, you can upload it via the method(s) you chose during the `gemican-quickstart` questionnaire. For this example, we'll use rsync over ssh:
make rsync_upload
That's it! Your site should now be live.
(The default `Makefile` and `devserver.sh` scripts use the `python` and `gemican` executables to complete its tasks. If you want to use different executables, such as `python3`, you can set the `PY` and `PELICAN` environment variables, respectively, to override the default executable names.)
