Issue
I following the steps, accord to https://github.com/dart-lang/custom-element-apigen:
- node/npm (v3.5.3) installed
- bower (v1.7.2) installed
- hydrolysis (v1.21.4) installed
.bowerrccreated with following content
{
"directory": "lib/src"
}
-
bower install --save paper-datatable(https://github.com/David-Mulder/paper-datatable) executed -
apigen.yamlcreated with following content
files_to_generate:
- paper-datatable\paper-datatable.html
- custom_element_apigen library add on pubspec.yaml
dependencies:
custom_element_apigen: ^0.2.1+1
pub run custom_element_apigen:update apigen.yamlcommand executed.
ERROR IN THIS COMMAND
First error: On Windows did not work. Details on https://github.com/dart-lang/custom-element-apigen/issues/43.
As a workaround I create process_elements.bat (instead process_elements.sh) with following content:
node packages\custom_element_apigen\src\js\analyze.js %1
I edit generate_dart_api.dart and changed the call .bat instead .sh to:
'D:/Users/Administrador/AppData/Roaming/Pub/Cache/hosted/pub.dartlang.org/custom_element_apigen-0.2.1+1/lib/src/js/process_elements.bat', [inputPath]);
Then, I got a workarround!
Second error, I did not resolve!
Now, occur the following problem when the command c:\dart-sdk\bin\pub run custom_element_apigen:update apigen.yaml is executed:
D:\Users\Administrador\WebstormProjects\Facilis>c:\dart-sdk\bin\pub run custom_e
lement_apigen:update apigen.yaml

Am I doing something wrong? or Is this a bug?
Thanks!
Solution
This is a bug, the package is untested on windows as it has primarily just been used by the polymer dart team.
It looks in general like the the fix just needs to be loading the .bat file as you already did and then also adjusting the paths to use the correct directory separator.
