When a DTL template includes other template files, those files don't need
to be compiled separately, and therefore can be given an extension different
from `source_ext` (such as `.dtli`) to avoid being compiled. This fix
allows rebar to find included dependencies with names `*.dtl*` rather
than `*.dtl` and properly determine if a template file needs to be recompiled.
The printed message is made more terse.
Example before applying patch:
ERROR: Compiling template src/view/test.dtl failed:
{error,{"src/view/test.dtl",
[{{4,7},
erlydtl_parser,
["syntax error before: ",["\"\\\"HELLO_WORLD\\\"\""]]}]}}
Example after applying patch:
ERROR: Compiling template "src/cmp_html_error_template.dtl" failed:
(line:3, col:12): ["syntax error before: ",["trans"]]
Added a backward compartible feature to specify `erlydtl_opts' options
for the DTL template compiler to allow inclusion of templates in different
directories with different compilation settings for each. E.g.:
{erlydtl_opts, [
[{doc_root, "src/view"}, {module_ext, "_dtl_vw"}]
, [{doc_root, "src"}, {module_ext, ""}, {recursive, false}]
, {out_dir, "ebin"}
, {compiler_options, [verbose, debug_info]}
]}.
The definition above is identical to this (the last two options
are duplicated in each list):
{erlydtl_opts, [
[{doc_root, "src/view"}
,{module_ext, "_dtl_vw"}
,{out_dir, "ebin"}
,{compiler_options, [verbose, debug_info]}]
, [{doc_root, "src"}
,{module_ext, ""}
,{out_dir, "ebin"}
,{compiler_options, [verbose, debug_info]}
,{recursive, false}]
]}.
In this case "src/view" and "src" directories containing template files
will be compiled. A new `recursive' option tells rebar_erlydtl_compiler
to search files recursively from a given doc_root. In the example above
the "src" directory won't be scanned recursively, and the target template
name for target beam modules won't have "_dtl_vw" suffix.
The latest version of erlydtl requires that custom tag modules be in
the path when templates are compiled. Without this change rebar silently
exits when using the custom_tags_modules option.
