Generates ad-hoc ID (a numeric string) on a basis of values passed as arguments.

Registers taggers in a global repository. To be changed to a pure fn some day.

Generates anti-spam HTML string containing randomly selected fields and values using validators/gen-required.

Transforms the given sequence of arguments args to a map by taking each consecutive pair and changing its first element into a keyword (using amelinium.utils/keyword-from-param) to become a key associated with its paired value.

Parses a string s with key=value assignments and returns a map with keys as keywords. Variables are resolved if they have [[ and ]] around.

Parses a string s with key=value assignments and returns a map with keys as strings. Variables are resolved if they have [[ and ]] around.

Helper to generate HTML for the form-field tag.

Helper to generate HTML for the form-fields tag.

Helper to generate HTML for the form-submit tag.

Helper to generate HTML for the form-submit tag.

Retrieves value of a field v from :params map of :form/errors key of the given ctx map. If there is no entry or value is nil or false, it looks it up directly in ctx. Returns a value or an empty string.

Prepares default form action attribute by removing form-errors from a query string for current page if the :action in args is not present. If the :action is present`, it is returned as is.

If the action is missing and there are no query params, nil is returned. If there is no form-errors in query params, nil is returned too.

This function takes care about a corner case where leaving form action empty on a rendered form would cause current form errors encoded in a query parameter string to be sent again to the same page, giving possibly misleading information about the form errors.

Obtains a language string from a context map ctx by trying the following keys: :language/str, :lang, :language and :language/default.

Obtains a language identifier (as keyword) from a context map ctx by trying the following keys: :language/str, :lang, :language and :language/default.

Generates HTML attribute list in a form of name= "value" from the given args map. Returns a string with each pair separated by a single space and the whole string prefixed with a single space (if it is not empty).

Escapes string s to be used in HTML using Selmer’s selmer.filter-parser/escape-html* function.

Initializes Selmer taggers.

Returns true if the given value is a keyword or a string expressing a keyword (with : symbol as its first character).

Transforms the given URI (a path expressed as a string) or a route name (a keyword) to a localized path using the detected (or given) language. Calls amelinium.common/lang-url. Tries to be very optimistic: if a path was given and there was no success in transforming it into localized variant, it will return it.

Returns last character of the given string s or nil.

Tries to translate tag parameters k and v using the given tr-sub-fn function (which should be a result of calling translator-sub). If the value of v is not a keyword or keyworded string (kw-param? applied to v does not return true) then a string of v is returned without calling a translation function. Any additional arguments are passed to a translation function as additional arguments.

Parses arguments using selmer.filter-parser/fix-filter-args function.

Interpolates values enclosed within [[ and ]] tokens by getting values associated with the obtained keys in ctx map. Additionally, parses form field values enclosed within [- and -] tokens by replacing them with default values transferred from propagated error data or, if there was no error, with values associated with keys in ctx map.

Translation function. Creates a translator by calling translator and prepares arguments from a template tag to be passed to it (the first being converted to a keyword). Returns a string or nil.

Translation function. Creates a translator by calling translator-sub and prepares arguments from a template tag to be passed to it (the first and second being converted to keywords). Returns a string or nil.

For the given context map ctx and optional translation function translations-fn it returns a translation function with predefined language, taking a translation key k and optional arguments.

The value of translations-fn argument is used as fallback when there is no :i18n/translator nor :i18n/translator-nd key found in a context map. It should be a function returned by the amelinium.i18n/translation-fn. If translations-fn is nil or false, it will fall back to a generic, globally initialized amelinium.i18n/translations.

For the given context map ctx and optional translation function translations-fn it returns a translation function with predefined language, taking a translation key k and optional arguments. If the first optional argument is present and it is not nil nor false then its value will become a name and the value of k will become a namespace for a translation key.

The value of translations-fn argument is used as fallback when there is no :i18n/translator-sub nor :i18n/translator-sub-nd key found in a context map. It should be a function returned by the amelinium.i18n/translation-fn. If translations-fn is nil or false, it will fall back to a generic, globally initialized amelinium.i18n/translations.

Encodes URL given as a string s using Java’s URLEncoder/encode.

Escapes certain characters (<, >, " and ') in the given string s by replacing them with character codes prefixed with % symbol.
