## Usage
|
|
|
|
Once this plugin is [installed](../README.md#installation), just replace
|
|
the plugin name `simple` with `semiliterate` in your `mkdocs.yml` file.
|
|
It accepts all of the same parameters, so `mkdocs` will still work as before,
|
|
and you will have immediate access to all of the following extensions.
|
|
(Note that this documentation assumes a familiarity with the
|
|
[usage](https://athackst.github.io/mkdocs-simple-plugin/mkdocs_simple_plugin/plugin/)
|
|
of the `simple` plugin.)

### Inclusion syntax
|
|
|
|
While extracting content from a file (because it matches one of the
|
|
`semiliterate` patterns, rather than just one of the `include_extensions`),
|
|
an unescaped expression of the form
|
|
|
|
`{! FILENAME YAML !}`
|
|
|
|
(which may span multiple lines) will trigger file inclusion. The FILENAME may
|
|
be a bare word, in which case it cannot contain whitespace, or it may be
|
|
enclosed in single or double quotes. Note that FILENAME is interpreted relative
|
|
to the directory in which the file containing the `{! .. !}` expression
|
|
resides. The YAML is interpreted exactly as the extraction options to a
|
|
`semiliterate` item as
|
|
[documented](https://athackst.github.io/mkdocs-simple-plugin/
|
|
mkdocs_simple_plugin/plugin/index.html#semiliterate)
|
|
for the `simple` extension. The text extracted from FILENAME
|
|
is interpolated at the current location in the file currently being written.
|
|
Recursive inclusion is supported.
|
|
|
|
The simplest example of such an inclusion directive is just
|
|
`{! boilerplate.md !}`, which (because of the conventions for extraction
|
|
parameters) simply interpolates the entire contents of `boilerplate.md`
|
|
at the current location.
|
|
|
|
For an example that uses more of the extraction parameters, the current
|
|
version number of mkdocs-semiliterate is extracted into the
|
|
[Overview](../README.md) of this documentation via
|
|
|
|
` {! ../README.md extract: { start: 'repo:.*(\{!.*!\})' }
|
|
terminate: Rationale
|
|
!}`
|
|
|
|
to take advantage of the beginning of the `setup.cfg` file:
|
|
```
|
|
{! ../setup.cfg terminate: long !}...
|
|
```
|
|
|
|
(and of course both of the code snippets just above are extracted into this
|
|
page with `{! ... !}`, as you can see in the
|
|
[source code](https://code.studioinfinity.org/glen/mkdocs-semiliterate/src/
|
|
branch/main/mkdocs_semiliterate/plugin.py)
|
|
for the plugin.)
|
|
|
|
Note that a `{! ... !}` directive must be in a line that semiliterate would
|
|
normally copy. That is, semiliterate does not examine lines after
|
|
the `terminate` regexp, or when no mode of extraction is active.
|
|
It also doesn't check any text written from lines that match these
|
|
special expressions, including `start` and `stop`.
|
|
Moreover, on such normally-transcribed lines,
|
|
it's the text **after** the application of any semiliterate `replace`ments that
|
|
is checked for `{! ... !}`.

`semiliterate` adds a couple of new plugin parameters to further tailor its

default values in parentheses at the beginning of each entry.
