- ErlyDTL
- =======
- ErlyDTL implements most but not all of the Django Template Language.
- Project homepage: http://code.google.com/p/erlydtl/
- Compilation
- -----------
- To compile ErlyDTL, type "make" in this directory.
- Template compilation
- --------------------
- Four ways:
- erlydtl:compile("/path/to/template.dtl", my_module_name)
- erlydtl:compile("/path/to/template.dtl", my_module_name, Options)
- erlydtl:compile(<<"<html>{{ foo }}</html>">>, my_module_name)
- erlydtl:compile(<<"<html>{{ foo }}</html>">>, my_module_name, Options)
- Options is a proplist possibly containing:
- doc_root - Included template paths will be relative to this directory;
- defaults to the compiled template's directory.
- custom_tags_dir - Directory of DTL files (no extension) includable as tags.
- E.g. if $custom_tags_dir/foo contains "<b>{{ bar }}</b>", then
- "{{ foo bar=100 }}" will evaluate to "<b>100</b>". Get it?
- vars - Variables (and their values) to evaluate at compile-time rather than
- render-time.
- reader - {module, function} tuple that takes a path to a template and returns
- a binary with the file contents. Defaults to {file, read_file}. Useful
- for reading templates from a network resource.
- compiler_options - Proplist passed directly to compiler:forms/2
- force_recompile - Recompile the module even if the source's checksum has not
- changed. Useful for debugging.
- Usage (of a compiled template)
- ------------------------------
- my_compiled_template:render(Variables) -> {ok, IOList} | {error, Err}
- Variables is a proplist, dict, gb_tree, or a parameterized module
- (whose method names correspond to variable names). The variable
- values can be atoms, strings, binaries, or (nested) variables.
- IOList is the rendered template.
- my_compiled_template:source() -> {FileName, CheckSum}
- Name and checksum of the original template file.
- my_compiled_template:dependencies() -> [{FileName, CheckSum}]
- List of names/checksums of templates included by the original template
- file. Useful for frameworks that recompile a template only when the
- template's dependencies change.
- Tests
- -----
- From a Unix shell, run:
- make test
- Note that the tests will create some output in examples/rendered_output.
