lh-vim-lib

Introduction

lh-vim-lib is a library that defines some common vim functions I use in my various plugins and ftplugins.

This library has been conceived as a suite of |autoload| plugins. As such, it requires Vim 7+. A few commands are defined.

As I only have access to a version 7.4-052 on travis-ci, let's say this is the minimum vim version I'll try to be compatible with. Until 2017 (v3.x) I was trying to be compatible with 7.3-429.

The complete documentation can be browsed.

Important:

Since Version 2.2.0, the naming policy of these autoload functions have been harmonized. Now, most names are in lower cases, with words separated by underscores.
Since version 3.2.7, it's no longer hosted on google-code but on github.
Version 4.0.0 breaks lh#let#if_undef() interface, deprecates CONFIRM(), requires vim 7.4-52.

UI functions

All the functions defined in ui-functions.vim are wrappers around Vim interactive functions. Depending on a configuration variable ((bpg):ui_type), they will delegate the interaction to a gvim UI function, or a plain text UI function (defined by vim, or emulated)

Possible values for (bpg):ui_type are: gui (default) or text.

In lh#ui#confirm() case, the option (bpg):ui_confirm_type can be set to 'std' to explicitly use confirm() instead of the old emulated version. The default is to use the emulated version of confirm(), which unlike the standard one permits to navigate between propositions with the cursor or tab keys to choose one.

`lh#ui#check()`	Emulates a checbox UI function
`lh#ui#combo()`	Emulates a combobox UI function

`lh#ui#switch()`	Emulates `switch()` in vim-script language
`lh#ui#which()`	Wrapper around functions like `lh#ui#confirm()` or `lh#ui#combo()` that returns the text of the selected item instead of the index of the selected item

Installation

Requirements: Vim 7.4, Vim 8 for lh#async feature.

Clone from the git repository

git clone [email protected]:LucHermitte/lh-vim-lib.git

Vim Addon Manager: (this is the preferred method as VAM handles dependencies).
```
ActivateAddons lh-vim-lib
```
Note that vim-flavor also handles dependencies which will permit to automatically import lh-vim-lib from plugins that use it:
```
flavor 'LucHermitte/lh-vim-lib'
```
Vundle/NeoBundle:
```
Bundle 'LucHermitte/lh-vim-lib'
```
