Export snippets from GitLab

export-gitlab-snippets.ps1

# Quick 'n' dirty script to export snippets from GitLab to local files. Useful if you're
# migrating to GitHub or just want to back up your snippets as files. Doesn't catch errors
# or anything like that, but what were you expecting for a Gist? :-) Also, this will only
# export snippets that are visible to you, so other users' private snippets are excluded.

# Tested with GitLab v8.5.1

$username = "username" # Your username goes here
$password = "password" # Your password goes here
$baseURL  = "https://your.gitlab.base.url" # Your GitLab base URL goes here
$lastSnippet = 80 # Change the number to the highest snippet number you have
$snippetFolder = "C:\your\snippet\folder" # Your snippet folder goes here

$ie = New-Object -com InternetExplorer.Application 
$ie.visible=$false
$ie.navigate("$baseURL/users/sign_in")
while($ie.ReadyState -ne 4) {start-sleep -m 100} 
$ie.document.getElementById("username").value= "$username" 
$ie.document.getElementById("password").value = "$password" 
$ie.document.getElementById("new_ldap_user").submit() # This is for LDAP logins - change the form ID according to how you log in
start-sleep 10 
$i = 0
while ($i -le $lastSnippet) {
    $ie.navigate("$baseURL/snippets/$i")
    while($ie.ReadyState -ne 4) {start-sleep -m 100} 
    if ($ie.Document.body.innerHTML -notmatch "HTTP 404") {
        $filename = $ie.Document.IHTMLDocument3_getElementsByTagName("strong")
        $filename | Select-Object -Property innerHTML -OutVariable filename
        $filename = $filename.innerHTML.ToString().Substring(1,($filename.innerHTML.ToString().Length) - 2)
        $ie.navigate("$baseURL/snippets/$i/raw")
        while($ie.ReadyState -ne 4) {start-sleep -m 100}
        $ie.Document.body.innerText | Out-File -FilePath "$snippetFolder\$filename"
    }
    $i++
}

Known issue: Will overwrite snippets if you happen to have more than one with the same name.
