Globals template

Finds all the templates the loader can find, compiles them and stores them in target. If zip is None , instead of in a zipfile, the templates will be stored in a directory. By default a deflate zip algorithm is used.

To switch to the stored algorithm, zip can be set to 'stored'. Each template returned will be compiled to the target folder or zipfile.

By default template compilation errors are ignored. In case a log function is provided, errors are logged. Add the items to the instance of the environment if they do not exist yet. This is used by extensions to register callbacks and configuration values without breaking inheritance. Load a template from a source string without using loader.

If the template has already been loaded and cached, its globals are updated with any new items. Load a template by name with loader and return a Template. If the template does not exist a TemplateNotFound exception is raised. Changed in version 3. Join a template with the parent. By default all the lookups are relative to the loader root so this method returns the template parameter unchanged, but if the paths should be relative to the parent template, this function can be used to calculate the real template name.

Returns a list of templates for this environment. If there are other files in the template folder besides the actual templates, the returned list can be filtered. If the loader does not support that, a TypeError is raised. If none of the names can be loaded a TemplatesNotFound exception is raised. If no templates were found and names contains Undefined , the message is more helpful. The central template object. This class represents a compiled template and is used to evaluate it.

Normally the template object is generated from an Environment but it also has a constructor that makes it possible to create a template instance directly using the constructor.

Every template object has a few methods and members that are guaranteed to exist. Modifications on the object are not supported. Template objects created from the constructor rather than an environment do have an environment attribute that points to a temporary environment that is probably shared with other templates created with the constructor and compatible settings.

The dict with the globals of that template. The loading name of the template. If the template was loaded from a string this is None. The filename of the template on the file system if it was loaded from there. Otherwise this is None. This method accepts the same arguments as the dict constructor: A dict, a dict subclass or some keyword arguments. If no arguments are given the context will be empty. These two calls do the same:. For very large templates it can be useful to not render the whole template at once but evaluate each statement after another and yield piece for piece.

This method basically does exactly that and returns a generator that yields one item after another as strings. It accepts the same arguments as render. Works exactly like generate but returns a TemplateStream. This works similar to render but returns a coroutine that when awaited returns the entire rendered template string. This requires the async feature to be enabled. An async version of generate. Works very similarly but returns an async iterator instead.

This method works like the module attribute when called without arguments but it will evaluate the template on every call rather than caching it. The template as module. This is used for imports in the template runtime but is also useful if one wants to access exported template variables from the Python layer:.

A template stream works pretty much like an ordinary python generator but it can buffer multiple items to reduce the number of total iterations.

Per default the output is unbuffered which means that for every unbuffered instruction in the template one string is yielded. If buffering is enabled with a buffer size of 5, five items are combined into a new string.

This is mainly useful if you are streaming big templates to a client via WSGI which flushes after each iteration. Dump the complete stream into a file or file-like object. Per default strings are written, if you want to encode before writing specify an encoding.

Jinja now comes with autoescaping support. However autoescaping is not yet enabled by default though this will most likely change in the future.

This makes it possible to enable and disable autoescaping on a per-template basis HTML versus text for instance. Intelligently sets the initial value of autoescaping based on the filename of the template. This is the recommended way to configure autoescaping if you do not want to write a custom function yourself. If you want to enable it for all templates created from strings or for all templates with.

Example configuration to turn it on at all times except if the template ends with. If nothing matches then the initial value of autoescaping is set to the value of default. Here a recommended setup that enables autoescaping for templates ending in '.

When implementing a guessing autoescape function, make sure you also accept None as valid template name. This will be passed when generating templates from strings. You should always configure autoescaping as defaults in the future might change. Inside the templates the behaviour can be temporarily changed by using the autoescape block see Autoescape Overrides. Jinja uses Python naming rules. Valid identifiers can be any combination of Unicode characters accepted by Python. Filters and tests are looked up in separate namespaces and have slightly modified identifier syntax.

Filters and tests may contain dots to group filters and tests by topic. These classes can be used as undefined types. The Environment constructor takes an undefined parameter that can be one of those classes or a custom subclass of Undefined. Whenever the template engine is unable to look up a name or access an attribute one of those objects is created and returned. Some operations on undefined values are then allowed, others fail.

The default undefined type. This undefined type can be printed and iterated over, but every other access will raise an UndefinedError :. Either None or the owner object that caused the undefined object to be created for example because an attribute does not exist. The exception that the undefined object wants to raise. This is usually one of UndefinedError or SecurityError. An undefined that barks on print and iteration as well as boolean tests and all kinds of comparisons.

There is also a factory function that can decorate undefined objects to implement logging on failures:.

Given a logger object this returns a new undefined class that will log certain failures. It will log iterations and printing. If no logger is given a default logger is created.

This defaults to Undefined. Undefined objects are created by calling undefined. To allow conversion to int by returning 0 you can implement your own:. Here a class that works like the regular Undefined but chokes on iteration:. The template context holds the variables of a template. It stores the values passed to the template and also the names the template exports. The context is immutable. Modifications on parent must not happen and modifications on vars are allowed from generated template code only.

A dict of read only, global variables the template looks up. These can either come from another Context , from the Environment. It must not be altered. The template local variables.

This list contains environment and context functions from the parent scope as well as local modifications and exported variables from the template. The template will modify this dict during template evaluation but filters and context functions are not allowed to modify it.

This set contains all the names the template exports. If you only want unique elements to be returned, use unique in conjunction with this. See Eager-Loading Elements opens new window for a full explanation of how to work with this parameter. Param Description afterPopulate Performs any post-population processing on elements.

The Normal. You might create a global template for any of the following reasons: 1 To ensure a set of macros, styles, autotext etc is available for all documents currently open in a single session but not for all sessions. When you work on a document, you can typically use only the settings stored in the template attached to that document or in the Normal template.

If you want to use any items that are stored in another template, you can load the other template when it is required. A global template can be unloaded temporarily until you close Word. After you have added a template, all items in that template will be available. If your Document template says "Normal" then there is no template attached to this document?? When you select an add-in the folder location where the add-in is stored is displayed at the bottom.

Add - Lets you add a new global template to the list of available global templates. Remove - Global templates can be removed and added at any time. Clearing the check box only unloads the template temporarily for the current session.
