System Configurations

This repository is created to consolidate the system settings and configurations to setup the Linux development environment. This includes bash run-configurations, neovim settings, local environment creation utility for C development and many other things would be added over time. Following are some notes which go along with the settings.

Using CENV

The local_env/cenv file is an executable shell script which implements the creation of a local environment akin to the Python virtual environment. We place the cenv file typically at ~/.local/bin/ and create an environment using cenv <env_name> which also activates the environment. The key combination ctrl + d deactivates the environment. This environment is nothing but a file system structure like below.

~/.local/share/cenv/<env_name>
                              |-include/
                              |-bin/
                              |-lib/
                              |-share/

When the cenv is active it automatically takes care of setting LD_LIBRARY_PATH, PKG_CONFIG_PATH and GI_TYPELIB_PATH accordingly. It povides us with a conveninent way to manage the built C binaries as different stages of development as well as helps avoiding installation of everything at /usr/local/bin which remains clean. When we need to build and install third-party packages we can do that with cenv as well just like we do with Python virtual environment. It works well with the meson build system. We can first setup the build directory for a meson project in the following manner and then build and install the binary inside cenv.

$ meson setup --prefix $CENV <build_dir_name>
$ cd build && ninja
$ ninja install

Doing installs the the binary in the aforementioned scope of the cenv. In this manner we can also maintain the inter- dependency of the softwares that we develop.

Using nvim

Using the nvim/init.vim needs that we are using the recent version of nvim for all underlying plugins to work in the expected manner. We also need to ensure that we installed nerd-fonts, Golang, ctag etc..

Bash Powerline

Use instructions from this guideline to install and configure bash powerline.
