Enhance automatically generated snippets

[EmilyGraceSeville7cf]

Use placeholders instead of:

• var
• file
• expr-list
• fmt
• cmd-line
• how

and the same terms enclosed inside square brackets. To be clear, generate: getline ${1:var} <${2:file} instead of getline var <file.

BTW, I also suggest preprocess initial terms replacing them for more human readable ones:

• var -> variable
• file -> path/to/file
• expr-list -> expressions
• fmt -> format
• cmd-line -> command

In other words, generate: getline ${1:variable} <${2:path/to/file} instead of getline var <file.

i was curious where such getline var <file came from...

// seems getline ${1:var} <${2:file} is the correct format.

and why this lsp server no auto compl feature, and no any trigger char, a bit weird... 😄

There is an awk script to generate doc.json (I don't remember it's name precise, but it's smth like that) file which is used then as a source for generated snippets

[Shane-XB-Qian]

oh, but anyway getline var <file looks was not a format can be recognized.

I'll take another look at generating docs when I have spare time but nowadays it's scarce.
