This is used to document the finding about the Padre::Plugin::Snippets plugin and the TextMate/snipMate integration that I have been planning with bowtie (Kevin) and implementing at the moment in Padre::Plugin::Moose. We will eventually migrate this feature into this plugin once it is mature.

Notes

• Snippet mode can be entered through <trigger><TAB>
• <trigger> should be matched on a word boundary that ends with the current position
• Shift-TAB traverses all variables (circular is a useful snipMate feature). Does not break snippet mode.
• Movement keys and deletion: Up/down/right/left/page up/page down/home/end/delete automatically exit snippet mode
• Cancel current selection when exiting snippet mode

Workflow

• Snippet mode OFF:
  • $line = the current line text preceding the cursor
  • Find $trigger for $line and the current active snippet bundle or exit
  • Find the snippet associated with trigger or exit
  • Find all variables in snippet of the form:
    ${index:default_value},${index} or $index
    e.g. $1, ${1:...}, ${1}
  • $cursor = the first variable that has the index of 1
  • Insert snippet
  • Select $cursor in snippet and position the cursor at the end of it.

• Snippet mode ON:

TODO

• Support extended syntax ${index:default_value:list_of_values}
