## DESCRIPTION
**blogc** compiles source files and templates into blog/website resources. It
gets one (or more) source files and a template, and generates an output file,
based on the template and the content read from the source file(s). It was
designed to be used with make(1).
`blogc` works on two modes:
* `entry`:
Default mode, first example in [SYNOPSIS][]. Accepts only one source
file, and process it as a single entry of the blog/website, like a static
page or a post.
* `listing`:
Listing mode, second example in [SYNOPSIS][], activated when
calling `blogc` with `-l` option. Accepts multiple source files, and allow
users to iterate over the content of all the source files to produce listing
pages, like indexes and feeds.
## OPTIONS
* `-d`:
Activates debug.
* `-i`:
Reads list of source files from standard input. Content of standard input is
parsed as a file where each line is a file path. Empty lines and lines
starting with `#` are ignored. If some source files are provided to command
line while using this option, they will be parsed **before** the files read
from standard input.
* `-l`:
Activates listing mode, allowing user to provide multiple source files. See
blogc-source(7) for details.
* `-D` <KEY>=<VALUE>:
Set global configuration parameter. <KEY> must be an ascii uppercase string,
with only letters, numbers (after the first letter) and underscores (after
the first letter). These parameters are available anywhere in templates,
but may be overridden by local configuration parameters set in source files.
See blogc-template(7) for details.
* `-p` <KEY>:
Show the value of a global configuration parameter right after the source
parsing and exits. This is useful to get parameters for your `Makefile`,
like the last page when using pagination, see blogc-pagination(7) for details.
* `-t` <TEMPLATE>:
Template file. It is a required option, if `blogc` needs to render something.
See blogc-template(7) for details.
* `-o` <OUTPUT>:
Output file. If provided this option, save the compiled output to the given
file. Otherwise, the compiled output is sent to `stdout`.
* `-v`:
Show program name, version and exit.
* `-h`:
Show help message and exit.
## FILES
The `blogc` command expects a template file blogc-template(7), one (or more)
source files blogc-source(7) and an output file, if wanted. Templates and source
files must have valid UTF-8 content.
## ENVIRONMENT
No environment variables are required by `blogc`, but global timezone will
be used by locale-dependant datetime input field descriptors (like `%c`), and
can be overridden using environment variables. See strftime(3).
## EXAMPLES
Build index from source files:
$ blogc -l -t template.tmpl -o index.html source1.txt source2.txt source3.txt
Build entry page from source file:
$ blogc -t template.tmpl -o entry.html entry.txt
## BUGS
**blogc** is based in handwritten parsers, that even being well tested, may be
subject of parsing bugs. Please report any issues to:
