# Tests for #507: mixed lower and upper case.

# we define a very simple table and just test whether the word rule
# matches when we encounter mixed case input. Since we do not define
# any caps rules we expect liblouis to ignore capitalization
table: |
  include tables/de-chardefs6.cti
  word mit 2345
  
tests:
  - [mit, t]
  - [Mit, t, {xfail: "returns 'mit' instead"}]
  - [MIT, t]
  - [mIt, t, {xfail: "returns 'mit' instead"}]
  - [miT, t, {xfail: "returns 'mit' instead"}]

# same test as above basically but this time using an always rule
# instead of a word rule
table: |
  include tables/de-chardefs6.cti
  always mit 2345
  
tests:
  - [mit, t]
  - [Mit, t, {xfail: "returns 'mit' instead"}]
  - [MIT, t]
  - [mIt, t, {xfail: "returns 'mit' instead"}]
  - [miT, t, {xfail: "returns 'mit' instead"}]

# here's another test similar to the first one just using a different
# input text
table: |
  include tables/de-chardefs6.cti

tests:
  - [man, m]
  - [Man, m, {xfail: "returns 'man' instead"}]
  - [MAN, m]
  - [maN, m, {xfail: "returns 'man' instead"}]
  - [mAn, m, {xfail: "returns 'man' instead"}]

# when enabling capitalization using a capsletter rule everything
# works as expected
table: |
  include tables/de-chardefs6.cti
  always mit 2345

  capsletter 46

tests:
  - [mit, t]
  - [Mit, $t]
  - [MIT, t]
  - [mIt, m$it]
  - [miT, mi$t]

# Now, let's try to add capitalization and remove it later in a pass2.
# This does not work. The mixed case mIt prevents contraction, so
# removing the capitalization doesn't help (at least no in all cases)

# Finally let's try to disable capitalization by correcting the input
# to be all lowercase. This works.
