msgctlint

msgctlint is a command-line tool used for linting C/C++ source code, specifically targeting potential issues related to message cataloging and internationalization (i18n). Its primary function is to analyze source files and identify patterns that might lead to problems when compiling or using localized message strings.

The tool checks for common mistakes such as missing or incorrect format specifiers in `gettext` function calls, mismatched translation string lengths, or improper usage of localization macros. By identifying these issues early in the development cycle, msgctlint helps developers avoid runtime errors and ensures better consistency in the internationalization process.

It integrates into build systems and development workflows, acting as a static analysis check. When run, msgctlint typically outputs a list of warnings or errors, indicating the file and line number where potential problems were detected. Developers can then review these reports and make the necessary corrections to their code. The specific checks performed by msgctlint can often be configured, allowing teams to tailor its behavior to their project's specific needs and coding standards. Its adoption contributes to more robust and maintainable multilingual software.
