This article provides some basic help when migrating existing Razor views into DotLiquid views. This includes some regular expressions that can be run in Visual Studio to do some of the tedious work required for larger views.

## Basic Razor Variables

When migrating an existing Razor view to DotLiquid all **@Model** references need to be replaced. In general, anything of the form **@Model.Variable** can be converted to **\[\[Model.Variable\]\]**.

### Regex to change these in VS

**Find** – @\\(?Model\\.(\[\\w\\.\]+)\\)?

**Replace** – \[\[Model.$1\]\]

## Basic Control Structures

@if can be converted to \[% if %\] \[% else %\] \[% endif %\]

@foreach can be converted to \[% for x in Y %\] \[% endfor %\]

When doing blocks like **if and for**, ending them with **-%\]** will cause them to not be a blank link in the rendered HTML.

See [GitHub](🔗) for more information about the basic DotLiquid syntax.

If there is complicated logic in the Razor view, it will need to be moved into the **ContentItemModel**.

If any properties on the **ContentItemModel** are not basic types, they need to return something that derives from Drop, or a list of something that derives from Drop.

## Zones

@Html.Zone(Model, "\[ZoneName\]") can be converted to \[% zone 'ZoneName' %\]

## URLs

@Url.ContentPage\<\[PageType\]\>() can be converted to \[% urlForPage '\[PageType\]' %\]

### Regex to change these in VS

**Find** – @\\(?Url\\.ContentPage\<(.\*)>\\(\\)\\)?

**Replace** – \[% urlForPage '$1' %\]

@Url.Action needs to be converted into the real URL, and then \[% urlFor '\[url\]' %\] - this will take microsites into account.

## Messages

@Html.Message("\[MessageName\]", "\[DefaultValue\]") can be converted to \[% siteMessage '\[MessageName\]' %\]

When doing this, ensure that **MessageProvider** contains a property **\[MessageName\]**, if it does not, add it and move the default value from the razor view into the **MessageProvider** property

### Regex to change these in VS

**Find** – @Html\\.Message\\("(.\*?)",.\*?\\)

**Replace** – \[% siteMessage '$1' %\]

**Find** – @MessageProvider\\.Current\\.(\[a-zA-Z\_-\]\*)

**Replace** – \[% siteMessage '$1' %\]

If any have site messages, translate, and a string format.

**Find** – @string\\.Format\\(MessageProvider\\.Current\\.(\[a-zA-Z\_-\]\*), T\\("(.\*?)"\\)\\)

**Replace** – {{::'\[% siteMessage '$1' %\]'.replace('{0}', '\[% translate '$2' %\]')}}

## Translations

@T("Translated String") can be converted to \[% translate 'Translated String' %\]


Some translations have an extra pair of parentheses @(T("Translated String")) wrapping the call to the translation function. The regex handles that as well.

### Regex to change these in VS

**Find** – @\\(?T\\("(.\*?)"\\)\\)?

**Replace** – \[% translate '$1' %\]

## Themed Partials

@Html.ThemedPartial("/Views/Directives/Folder/File.cshtml") can be converted to \[% translate 'Folder-file' %\]

### Regex to change these in VS

**Find** – @Html\\.ThemedPartial\\("/Views/Directives/(\[a-zA-Z\_-\]\*)/(\[a-zA-Z\_-\]\*)\\.cshtml"\\)

**Replace** – \[% partialView '$1-$2' %\]

## Popups

@Html.Action("GenericPopupPartial", "Shared", new { containerName = "popup-deletewishlist", BodyHtml = Model.DeleteWishlistMessage, Title = @T("Delete Wishlist") })

Needs to be switched to:

\<isc-popup-template title="\[% translate 'Delete Wishlist'%\]" container-id="popup-deletewishlist">



## Razor Helpers

@helpers can sometimes be converted into captures, as long as they are not passed in parameters.
