Como posso usar \if para inserir uma nova linha automaticamente quando meu texto for muito longo?

Question

Tenho uma seção em meu documento onde o espaço para escrita é limitado e quando há uma entrada de texto muito longa, ela não fica bem porque os pontos abrangem duas linhas, conforme mostrado na primeira imagem abaixo. Especificamente, gostaria de inserir automaticamente uma nova linha após as entradas "Comunicação eficaz" ou "Experiência de trabalho internacional" e ter os pontos recuados na nova linha. Por exemplo, deve haver um limite para o comprimento da linha: neste caso, quero defini-lo como 20pt. Não entendo qual \if usar e como determinar o comprimento da linha anterior para usá-la como condição. Se \if não for o caminho a seguir, existe alguma outra maneira de fazer isso?

Quero modificar o seguinte trecho de código:

% \pointskill[<indent>]{<icon>}{<description>}{<points>}[<maxpoints>] creates
% | [indent] [icon]  description  \hfill  ● ● ● ○ ○ |
% -- inspired by arravc.cls by LianTze Lim: https://github.com/liantze/AltaCV
\NewDocumentCommand{\pointskill}{ O{0em} m m m O{5} }{%
    \hspace{#1} \cvicon{#2} ~ #3 \hfill%
    \ifdim#3<20pt\newline\hspace{20pt} \fi % my attempt to enter a new line, but I can't figure it out; #3 is the text entry variable
    \foreach \x in {1,...,#5}{%
        \space%
        {\ifnumgreater{\x}{#4}{\color{skillbg}}{\color{iconcolor}}% from etoolbox
        % don't use totalheight; see https://tex.stackexchange.com/a/41014
        \raisebox{0.5\height-0.4ex}{\scriptsize\faCircle}%
        }
    }\par%
}

EDIT: Aqui está o exemplo mínimo de trabalho. Reduzi o máximo que pude (o arquivo .cls tinha mais de 600 linhas). Essencialmente, quero modificar o comando que começa com a linha \NewDocumentCommand{\pointskill}em class.cls para quebrar automaticamente as linhas se elas forem muito longas.

Saída atual:

Resultado desejado*:

*Eu só quero que as entradas da imagem1 que abrangem várias linhas sejam como na imagem2.

Você pode usar \settowidth{length register}{content}o calcpacote para armazenar a largura de algum conteúdo como comprimento (em pt).

MWE:

\documentclass[10pt,ragged2e]{altacv}
\usepackage{calc}
\usepackage{paracol}
\usepackage[sfdefault]{ClearSans}

\newcommand{\cvicon}[1]{\makebox[1.5em]{\color{accent}#1}}
\newlength{\skillswidth}
\NewDocumentCommand{\pointskill}{ O{0em} m m m O{5} }{%
    \hspace{#1} \cvicon{#2} ~ #3 \hfill%
    \settowidth{\skillswidth}{#3}%
    \ifdim\skillswidth>100pt\newline\hspace{22pt}\fi
    \foreach \x in {1,...,#5}{%
        \space%
        {\ifnumgreater{\x}{#4}{\color{body!30}}{\color{accent}}%
        \scriptsize\faCircle%
        }
    }\par%
}

\begin{document}
\columnratio{0.45}
\definecolor{accent}{rgb}{0.20,0.50,0.20}

\begin{paracol}{2}
\cvsection{Skills}
\pointskill{\faBolt}{Effective communication}{5}[5]
\pointskill{\faChild\faUsers}{International work experience}{4}[5]
\pointskill{\faToggleOn}{Living abroad}{5}[5]
\pointskill{\faGavel}{IPR}{3}[5]
\pointskill{\faAngellist}{Project coordination}{3}[5]
\pointskill{\faBalanceScale}{Ethics}{5}[5]
\end{paracol}
\end{document}

Mas não parece ótimo. Os marcadores na nova linha parecem maiores e mais distantes (embora sejam exatamente iguais às outras linhas).

Eu optaria por quebras de linha manuais:

\documentclass[10pt,ragged2e]{altacv}
\usepackage{calc}
\usepackage{paracol}
\usepackage[sfdefault]{ClearSans}

\newcommand{\cvicon}[1]{\makebox[1.5em]{\color{accent}#1}}
\NewDocumentCommand{\pointskill}{ O{0em} m m m O{5} }{%
    \hspace{#1} \cvicon{#2} ~ #3\hfill%
    \foreach \x in {1,...,#5}{%
        \space%
        {\ifnumgreater{\x}{#4}{\color{body!30}}{\color{accent}}%
        \scriptsize\faCircle%
        }
    }\par%
}

\begin{document}
\columnratio{0.45}
\definecolor{accent}{rgb}{0.20,0.50,0.20}

\begin{paracol}{2}
\cvsection{Skills}
\pointskill{\faBolt}{Effective\\\hspace{26pt}communication}{5}[5]
\pointskill{\faChild\faUsers}{International\\\hspace{26pt}work experience}{4}[5]
\pointskill{\faToggleOn}{Living abroad}{5}[5]
\pointskill{\faGavel}{IPR}{3}[5]
\pointskill{\faAngellist}{Project coordination}{3}[5]
\pointskill{\faBalanceScale}{Ethics}{5}[5]
\end{paracol}
