proc diffFiles(path1, path2: string): tuple[output: string, same: bool] {. ...raises: [OSError, IOError, ValueError], tags: [ExecIOEffect, ReadIOEffect, RootEffect], forbids: [].}: Returns a human readable diff of files path1, path2, the exact form of which is implementation defined. Source Edit
proc diffStrings(a, b: string): tuple[output: string, same: bool] {. ...raises: [IOError, OSError, ValueError], tags: [ReadEnvEffect, ReadIOEffect, WriteIOEffect, WriteDirEffect, ExecIOEffect, RootEffect], forbids: [].}: Returns a human readable diff of a, b, the exact form of which is implementation defined. See also experimental.diff.
Example:

let a = "ok1\nok2\nok3\n" let b = "ok1\nok2 alt\nok3\nok4\n" let (c, same) = diffStrings(a, b) doAssert not same let (c2, same2) = diffStrings(a, a) doAssert same2

Example: cmd: -r:off

let a = "ok1\nok2\nok3\n" let b = "ok1\nok2 alt\nok3\nok4\n" echo diffStrings(a, b).output

proc isGitRepo(dir: string): bool {....raises: [OSError, IOError], tags: [ ExecIOEffect, ReadIOEffect, RootEffect], forbids: [].}: This command is used to get the relative path to the root of the repository. Using this, we can verify whether a folder is a git repository by checking whether the command success and if the output is empty. Source Edit

template retryCall(maxRetry = 3; backoffDuration = 1.0; call: untyped): bool: Retry call up to maxRetry times with exponential backoff and initial duraton of backoffDuration seconds. This is in particular useful for network commands that can fail.
Example:

doAssert not retryCall(maxRetry = 2, backoffDuration = 0.1, false) var i = 0 doAssert: retryCall(maxRetry = 3, backoffDuration = 0.1, (i.inc; i >= 3)) doAssert retryCall(call = true)
