Buildhosts¶
Contents
To get best results from build, its recommend to install additional packages on build hosts (see utils/searx.sh).:
sudo -H ./utils/searx.sh install buildhost
This will install packages needed by searx:
$ sudo -H apt-get install -y \
python3-dev python3-babel python3-venv \
uwsgi uwsgi-plugin-python3 \
git build-essential libxslt-dev zlib1g-dev libffi-dev libssl-dev \
libprotobuf-dev protobuf-compiler \
shellcheck
$ sudo -H pacman -S --noconfirm \
python python-pip python-lxml python-babel \
uwsgi uwsgi-plugin-python \
git base-devel libxml2 \
protobuf \
shellcheck
$ sudo -H dnf install -y \
python python-pip python-lxml python-babel \
uwsgi uwsgi-plugin-python3 \
git @development-tools libxml2 \
ShellCheck protobuf-compiler protobuf-devel
and packages needed to build docuemtation and run tests:
$ sudo -H apt-get install -y \
firefox graphviz imagemagick texlive-xetex librsvg2-bin \
texlive-latex-recommended texlive-extra-utils fonts-dejavu \
latexmk
$ sudo -H pacman -S --noconfirm \
firefox graphviz imagemagick texlive-bin extra/librsvg \
texlive-core texlive-latexextra ttf-dejavu
$ sudo -H dnf install -y \
firefox graphviz graphviz-gd ImageMagick librsvg2-tools \
texlive-xetex-bin texlive-collection-fontsrecommended \
texlive-collection-latex dejavu-sans-fonts dejavu-serif-fonts \
dejavu-sans-mono-fonts
Build docs¶
Most of the sphinx requirements are installed from git://setup.py and the
docs can be build from scratch with make docs. For better math and image
processing additional packages are needed. The XeTeX needed not only for PDF
creation, its also needed for Math equations when HTML output is build.
To be able to do Math support for HTML outputs in Sphinx without CDNs, the math are rendered
as images (sphinx.ext.imgmath extension).
Here is the extract from the git://docs/conf.py file, setting math renderer
to imgmath:
html_math_renderer = 'imgmath'
imgmath_image_format = 'svg'
imgmath_font_size = 14
If your docs build (make docs) shows warnings like this:
WARNING: dot(1) not found, for better output quality install \
graphviz from https://www.graphviz.org
..
WARNING: LaTeX command 'latex' cannot be run (needed for math \
display), check the imgmath_latex setting
you need to install additional packages on your build host, to get better HTML output.
$ sudo apt install graphviz imagemagick texlive-xetex librsvg2-bin
$ sudo pacman -S graphviz imagemagick texlive-bin extra/librsvg
$ sudo dnf install graphviz graphviz-gd texlive-xetex-bin librsvg2-tools
For PDF output you also need:
$ sudo apt texlive-latex-recommended texlive-extra-utils ttf-dejavu
$ sudo pacman -S texlive-core texlive-latexextra ttf-dejavu
$ sudo dnf install \
texlive-collection-fontsrecommended texlive-collection-latex \
dejavu-sans-fonts dejavu-serif-fonts dejavu-sans-mono-fonts \
ImageMagick
Lint shell scripts¶
To lint shell scripts, we use ShellCheck - A shell script static analysis tool.
$ sudo apt install shellcheck
$ sudo pacman -S shellcheck
$ sudo dnf install ShellCheck
