Use a config file to specify relabeling options?

[aarppe]

Use initial rows in crk.altlabel.tsv to specify what relabeling options are made available, and what they will be named.

1. First row gives internal names for the various relabeling options.
2. Second row (SELECTION-LABEL) gives the names that iDict will use for showing relabling options.
3. Third row (SHOW-LABEL) will indicate whether the corresponding relabeling option will be shown (True) or not (False) in iDict.

E.g. for itwêwina, crk.altlabel.tsv contains the following first three rows, which already would support this modification:

ROW/COLUMN	1	2	3	4	5	6
1	FST TAG	LINGUISTIC (SHORT)	LINGUISTIC (LONG)	ENGLISH	NÊHIYAWÊWIN	EMOJI
2	SELECTION-LABEL	short linguistic labels	long linguistic labels	plain English labels	nêhiyawêwin labels	emojis
3	SHOW-LABEL	True	True	True	True	False

I will NOT implement this. I could be convinced to add configuration using a dedicated configuration file such as a .toml. However, I am not creating a mini-format in crk.altlabel.tsv.

Configurability is my primary goal, so added a question mark to the issue title. So, ok, using .toml, would something like the following work?:

[relabeling-1]
altlabelColumn = 1
morphodictLabel = "FST-style tags"
morphodictShow = false
morphodictOrder = 0

[relabeling-2]
altlabelColumn = 2
morphodictLabel = "short linguistic labels"
morphodictShow = true
morphodictOrder = 3

[relabeling-3]
altlabelColumn = 3
morphodictLabel = "long linguistic labels"
morphodictShow = true
morphodictOrder = 4

[relabeling-4]
altlabelColumn = 4
morphodictLabel = "plain English labels"
morphodictShow = true
morphodictOrder = 1

[relabeling-5]
altlabelColumn = 4
morphodictLabel = "nêhiyawêwin labels"
morphodictShow = true
morphodictOrder = 2

[relabeling-6]
altlabelColumn = 6
morphodictLabel = "emojis"
morphodictShow = false
morphodictOrder = 0

I don’t think we need this just yet, but when we do get to it, if I were to
apply the mallet of simplicity here, I would propose:

• Labels come from the first row of the TSV file.
• Relabelling order can come from the order of the columns in the TSV
  file too.
• Let’s not have multiple names for the same thing. Instead of supporting
  two labels “Linguistic (short)” and “short linguistic labels”, pick one
  and stick to it. That is, Internal name = external name because Python
  strings and dict keys do support spaces.

This leaves only one really configurable thing, which is whether a column
should be shown in the UI or not. I propose adding this as a setting in
settings.py, where it could look like this:

# Which relabellings to show in the UI. These are opt-in so that people
# can add columns to the TSV file for testing without having them
# immediately show up on the web.
#
# It is a set, not a list, because the actual order comes from the .tsv
# file.
MORPHODICT_SHOWN_RELABELINGS = {
    "Linguistic (short)",
    "😎",
    …
}

Presumably admins could see all the relabelling options, with something to
indicate which are not yet public.
