|
FUNCTIONS *idris-vim-functions*
|
|
|
|
All of the functions in idris-vim are essentially just calls back to the REPL,
|
|
so documentation for each of them is also available there.
|
|
|
|
IdrisDocumentation *IdrisDocumentation*
|
|
Shows internal documentation of the primitive under the cursor.
|
|
|
|
Mapped to '<LocalLeader>_h' by default.
|
|
|
|
IdrisResponseWin *IdrisResponseWin*
|
|
This opens an idris response window in a new pane.
|
|
|
|
Mapped to '<LocalLeader>_i' by default.
|
|
|
|
IdrisShowType *IdrisShowType*
|
|
This shows the type of the name under the cursor (or, if the cursor happens
|
|
to be over a metavariable, a bit more information about its context).
|
|
|
|
Mapped to '<LocalLeader>_t' by default.
|
|
|
|
IdrisReload *IdrisReload*
|
|
This reloads the file and type-checks the file in the current buffer.
|
|
|
|
Mapped to '<LocalLeader>_r' by default.
|
|
|
|
IdrisEval *IdrisEval*
|
|
This prompts for an expression and then evaluates it in the REPL, then
|
|
returns the result.
|
|
|
|
Mapped to '<LocalLeader>_e' by default.
|
|
|
|
IdrisCaseSplit *IdrisCaseSplit*
|
|
When the cursor is over a variable in a pattern match clause or case
|
|
expression, this splits the variable into all well-typed patterns.
|
|
|
|
Mapped to '<LocalLeader>_c' by default
|
|
|
|
IdrisAddClause *IdrisAddClause*
|
|
When the cursor is at a type declaration this creates a new clause for that
|
|
signature.
|
|
|
|
By default mapped to '<LocalLeader>_d' for an ordinary top-level definition,
|
|
'<LocalLeader>_b' for a typeclass instance definition, and
|
|
'<LocalLeader>_md' to add a pattern-matching proof clause.
|
|
|
|
IdrisAddMissing: *IdrisAddMissing*
|
|
When the cursor is over a function, this adds all clauses necessary to make
|
|
that function cover all inputs. This also eliminates clauses which would
|
|
lead to unification errors from appearing.
|
|
|
|
Mapped to '<LocalLeader>_m' by default
|
|
|
|
IdrisRefine: *IdrisRefine*
|
|
Refines the item the cursor is over (applies the name and fills in any
|
|
arguments which can be filled in via unification)
|
|
|
|
Mapped to '<LocalLeader>_f' by default
|
|
|
|
IdrisProofSearch: *IdrisProofSearch*
|
|
This attempts to find a value for the metavariable it was called on by
|
|
looking at the rest of the code. It can also be called with hints, which
|
|
are functions that can apply to help solve for the metavariable.
|
|
|
|
Mapped to '<LocalLeader>_o' without hints and '<LocalLeader>p' with hints by
|
|
default
|
|
|
|
IdrisMakeWith: *IdrisMakeWith*
|
|
When the cursor is over a pattern clause and this is called, it creates a
|
|
new with clause.
|
|
|
|
Mapped to '<LocalLeader>_w' by default
|
|
|
|
IdrisMakeLemma: *IdrisMakeLemma*
|
|
When the cursor is over a metavariable and this is called, it creates a new
|
|
top-level definition to solve the metavariable.
|
|
|
|
Mapped to '<LocalLeader>_l' by default
|
|
|
|

|
TROUBLESHOOTING *idris-vim-troubleshooting*
|
|
|
|
If this isn't working for you, make sure that:
|
|
|
|
* There is an Idris REPL running
|
|
* For syntax checking, you have syntastic installed
|
|
* The plugins mappings exists and don't conflict with anything else installed
|
|
(You can use ':map' to check. There should be mappings similar to
|
|
'\h * :call IdrisShowDoc()'.)
|
|
* Vim recognizes you're in an idris file (you can use ':verb set ft' to check)
|
|
|
|
If none of this works, check to issue tracker on github and if nothing is
|
|
there create an issue with a detailed description of the problem.
