Include/Import files in loop

[jradek]

Hi,

I try to import/include files within a loop, like this.

• Variables FILENAMES=( file1.txt file2.txt )

• Template

  {{#FILENAMES}}
  Content of {{.}}
  {{> .}}
  {{/FILENAMES}}

  The statement {{> .}} triggers the error

  cat: .: Is a directory

I tried to debug the source code, with my limited knowledge about bash scripting, and the error seems to be in function moParse around line 657 during the call of moPartial. Inside moPartial, the local variable moFilename is assigned to .. So the actual content of the current iteration, i.e. file1.txt was not passed.

I'm not sure, if the thing I try to accomplish is a limitation of bash or an actual bug in mo.

Thanks, JR

This isn't really a limitation of Bash. The error could be seen as a bug in mo, but the real problem is that your use case falls into the category of logic, which Mustache templates do not support. If you want to demo this yourself, you could start with this demo, which uses the JavaScript library: https://codepen.io/fidian/pen/dwKGWV

This is not the right way to use a mustache template. You may want to consider writing a function to do the same thing. There's an example named demo/function-for-advanced-looping that illustrates the function. You'll need to source mo into the environment so it can access the functions, which is why the example says . ../mo.
