/** * Returns the new version resulting from an increment by release type. * * `premajor`, `preminor` and `prepatch` will bump the version up to the next version, * based on the type, and will also add prerelease metadata. * * If called from a non-prerelease version, the `prerelease` will work the same as * `prepatch`. The patch version is incremented and then is made into a prerelease. If * the input version is already a prerelease it will simply increment the prerelease * metadata. * * If a prerelease identifier is specified without a number then a number will be added. * For example `pre` will result in `pre.0`. If the existing version already has a * prerelease with a number and its the same prerelease identifier then the number * will be incremented. If the identifier differs from the new identifier then the new * identifier is applied and the number is reset to `0`. * * If the input version has build metadata it will be preserved on the resulting version * unless a new build parameter is specified. Specifying `""` will unset existing build * metadata. * @param version The version to increment * @param release The type of increment to perform * @param prerelease The pre-release metadata of the new version * @param build The build metadata of the new version * @returns */export function increment( version: SemVer, release: ReleaseType, prerelease?: string, build?: string,): SemVer { let result: SemVer; switch (release) { case "premajor": result = { major: version.major + 1, minor: 0, patch: 0, prerelease: pre(version.prerelease, prerelease), build: parseBuild(version.build, build), }; break; case "preminor": result = { major: version.major, minor: version.minor + 1, patch: 0, prerelease: pre(version.prerelease, prerelease), build: parseBuild(version.build, build), }; break; case "prepatch": result = { major: version.major, minor: version.minor, patch: version.patch + 1, prerelease: pre(version.prerelease, prerelease), build: parseBuild(version.build, build), }; break; // If the input is a non-prerelease version, this acts the same as // prepatch. case "prerelease": if (version.prerelease.length === 0) { result = { major: version.major, minor: version.minor, patch: version.patch + 1, prerelease: pre(version.prerelease, prerelease), build: parseBuild(version.build, build), }; break; } else { result = { major: version.major, minor: version.minor, patch: version.patch, prerelease: pre(version.prerelease, prerelease), build: parseBuild(version.build, build), }; break; } case "major": // If this is a pre-major version, bump up to the same major version. // Otherwise increment major. // 1.0.0-5 bumps to 1.0.0 // 1.1.0 bumps to 2.0.0 if ( version.minor !== 0 || version.patch !== 0 || version.prerelease.length === 0 ) { result = { major: version.major + 1, minor: 0, patch: 0, prerelease: [], build: parseBuild(version.build, build), }; break; } else { result = { major: version.major, minor: 0, patch: 0, prerelease: [], build: parseBuild(version.build, build), }; break; } case "minor": // If this is a pre-minor version, bump up to the same minor version. // Otherwise increment minor. // 1.2.0-5 bumps to 1.2.0 // 1.2.1 bumps to 1.3.0 if ( version.patch !== 0 || version.prerelease.length === 0 ) { result = { major: version.major, minor: version.minor + 1, patch: 0, prerelease: [], build: parseBuild(version.build, build), }; break; } else { result = { major: version.major, minor: version.minor, patch: 0, prerelease: [], build: parseBuild(version.build, build), }; break; } case "patch": // If this is not a pre-release version, it will increment the patch. // If it is a pre-release it will bump up to the same patch version. // 1.2.0-5 patches to 1.2.0 // 1.2.0 patches to 1.2.1 if (version.prerelease.length === 0) { result = { major: version.major, minor: version.minor, patch: version.patch + 1, prerelease: [], build: parseBuild(version.build, build), }; break; } else { result = { major: version.major, minor: version.minor, patch: version.patch, prerelease: [], build: parseBuild(version.build, build), }; break; } // 1.0.0 "pre" would become 1.0.0-0 // 1.0.0-0 would become 1.0.0-1 // 1.0.0-beta.0 would be come 1.0.0-beta.1 // switching the pre identifier resets the number to 0 case "pre": result = { major: version.major, minor: version.minor, patch: version.patch, prerelease: pre(version.prerelease, prerelease), build: parseBuild(version.build, build), }; break; default: throw new Error(`invalid increment argument: ${release}`); } return result;}
