How do I set parameters for margins and justification within a tasks environment?

Question

I would like to know how to control three aspects of the tasks environment:

• How to eliminate extraneous space before the task counter,
• How to control the space between tasks
• How to set the paragraph formatting universally

In the following example, I would like the task numbers 1 and 5 to be flush with the left margin. I would also like to add space between the tasks so that, for example, task 5 and 6 are not so close together. Finally, I would like to set the paragraph formatting within each task to \raggedright without having to manually do it.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[margin=1in]{geometry}
\newcommand\sample{This is a sample sentence that spans more than one line of the final documents.}
\usepackage{tasks}
\usepackage{enumitem}
\setlength{\parindent}{0pt}
\begin{document}

\noindent
\raisebox{0pt}[0pt][0pt]{\rule[-4in]{0.4pt}{4in}}%%

\sample \sample \sample
\begin{tasks}[counter-format={\bfseries tsk[1].}](4)
  \task This 
  \task that 
  \task something else
  \task something even more
  \task \sample \sample
  \task \sample more more more
  \task \raggedright\texttt{\detokenize{\raggedright}} set here. \sample
  \task something
\end{tasks}

\end{document}

Answer 1

here is a solution, with the help of the etoolbox package for the last requirement:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[margin=1in, showframe, nomarginpar]{geometry}
\newcommand\sample{This is a sample sentence that spans more than one line of the final documents.}
\usepackage{tasks}
\usepackage{enumitem}
\setlength{\parindent}{0pt}
\usepackage{etoolbox}

\AtBeginEnvironment{tasks}{\raggedright}
\settasks{column-sep=1.5em, item-indent=1.3333em}%

\begin{document}

\noindent
\raisebox{0pt}[0pt][0pt]{\rule[-4in]{0.4pt}{4in}}%%

\sample \sample \sample
\begin{tasks}[counter-format={\bfseries tsk[1].}](4)
  \task This
  \task that
  \task something else
  \task something even more
  \task \sample \sample
  \task \sample more more more
  \task \raggedright\texttt{\detokenize{\raggedright}} set here. \sample
  \task something
\end{tasks}

\end{document} 

Answer 2

Settingcolumn-sep=1em, item-indent=1.3333em yields the results you desire:

The lengths are defined as

where item-offset I think should have been label-offset.

Notes:

• The defaults are label-width=1em and label-offset=0.3333em. Hence, setting item-indent=1.3333em yields the task counter aligned with the margin.

• The default for column-sep=0pt hence setting that value will increase the horizontal spacing.

• You can just set \raggedright before the \begin{tasks} and that will be in effect for all the tasks.

Code:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[margin=1in]{geometry}
\newcommand\sample{This is a sample sentence that spans more than one line of the final documents.}
\usepackage{tasks}
\usepackage{enumitem}
\setlength{\parindent}{0pt}
\begin{document}
\noindent
\raisebox{0pt}[0pt][0pt]{\rule[-4in]{0.4pt}{4in}}%%
\sample \sample \sample
{\raggedright%
\begin{tasks}counter-format={\bfseries tsk[1].}, column-sep=1em, item-indent=1.3333em
  \task This 
  \task that 
  \task something else
  \task something even more
  \task \sample \sample
  \task \sample more more more
  \task \raggedright\texttt{\detokenize{\raggedright}} set here. \sample
  \task something
\end{tasks}}
\end{document}
