For me at least, it's really easy to do more work than necessary during
development, when just a bit of forethought would have paid off handsomely.
For example, I recently tweaked the clean_headline method for the
javascript importer. Here is a list of my mistakes:
*Mistake 1:* Thinking that this project would be quick ;-) Had I known that
I would spend several hours on it I might have spent more time making each
iteration easier.
*Mistake 2*: To test this I *reopened* ekr.leo, my personal test outline.
I then executed a node containing just a call to c.recursiveImport.
I then *manually expanded* the resulting outline with expand-all-subheads
and looked at the results.
Doing expand-all-subheads was surprising clumsy. Only much later did I
realize (Doh!) that the following would work:
c.recursiveImport(...)
c.expandAllSubheads()
This works because c.recursiveImport() selects the newly-created top-level
node and c.expandAllSubheads() works on the presently selected node.
*Mistake 3*: Not using a unit test to drive development. That is, not
using the "stupendous Aha". At last I created the following @test node:
g.cls()
import imp
import leo.plugins.importers.javascript as js
imp.reload(js)
x = js.JS_Importer(c.importCommands)
table = [
'''window.addEventListener('mouseup', function (e) {''',
'''window.addEventListener ('message', function (e) {''',
'.then((response) => {',
]
for s in table:
print(s)
h = x.clean_headline(s, trace=True)
print(h)
print('')
Not great, but it uses imp.reload so that I didn't have to reload ekr.leo
to test problematic cases.
*Mistake 4*: Not using imp.reload in the recursive import script.
*Mistake 5*: Not binding a keystroke to the recursive import script.
*Summary*
This has been a catalog of impatience creating more work than necessary in
the long run.
