# Home73k
|
|
|
|
Personal website with blog.
|
|
|
|
## Blog posts
|
|
|
|
Posts are markdown files stored under `priv/content` and parsed by [Earmark](https://hexdocs.pm/earmark/Earmark.html). This can be configured in `config.exs` under `config :home73k, :app_global_vars, blog_content: "path/to/content"`
|
|
|
|
### Syntax highlighting
|
|
|
|
For the challenge of it, and to keep user's browsers from having to run javascript just to highlight some code, I chose to do server-side syntax highlighting.
|
|
|
|
Due to the lexer limitations of elixir-native solutions, the highlighter uses [Chroma](https://github.com/alecthomas/chroma) by calling its command-linie-interface via [System.cmd](https://hexdocs.pm/elixir/System.html#cmd/3)
|
|
|
|
However, this requires installing [golang](https://golang.org/doc/install) as well as chroma. You can add go to your path, but once chroma is installed, just make sure Home73k's `config.exs` is configured to point directly to the chroma binary under `config :home73k, :app_global_vars, chroma_bin: "path/to/bin/chroma"` -- `"priv/go/bin/chroma"` by default.

## Deploying
|
|
|
|
### New versions
|
|
|
|
When improvements are made, we can update the deployed version like so:
|
|
|
|
```shell
|
|
cd /opt/home73k
|
|
git pull
|
|
mix deps.get --only prod
|
|
MIX_ENV=prod mix compile
|
|
# update chroma in priv gopath
|
|
GOPATH=$(pwd)/priv/go go get -u github.com/alecthomas/chroma/cmd/chroma
|
|
# rebuild static assets:
|
|
rm -rf priv/static/*
|
|
npm run deploy --prefix ./assets
|
|
MIX_ENV=prod mix phx.digest
|
|
MIX_ENV=prod mix release --overwrite
|
|
# test starting it:
|
|
MIX_ENV=prod _build/prod/rel/home73k/bin/home73k start
|
|
```
|
|
|
|
