how can I limit the cpu usage of ccls?

[cxwx]

Could I set the limit of the cpus in .ccls config file?

limit cpu core for ccls

Thanks! It works. Is there any method to config it without compiling by oneself? So that I could use the homebrew version of ccls.

if you are using vscode, try "ccls.index.threads": <number>,

or you can add json into ccls launch arg --init, see https://github.com/MaskRay/ccls/blob/master/src/main.cc#L48

if I use ale, they only support

call ale#Set('cpp_ccls_executable', 'ccls')
call ale#Set('cpp_ccls_init_options', {})
call ale#Set('c_build_dir', '')

call ale#linter#Define('cpp', {
\   'name': 'ccls',
\   'lsp': 'stdio',
\   'executable': {b -> ale#Var(b, 'cpp_ccls_executable')},
\   'command': '%e',
\   'project_root': function('ale#handlers#ccls#GetProjectRoot'),
\   'initialization_options': {b -> ale#handlers#ccls#GetInitOpts(b, 'cpp_ccls_init_options')},
\})

Is there any way to set "ccls.index.threads" ? I don't find the correct way

if you are using vscode, try "ccls.index.threads": <number>,

or you can add json into ccls launch arg --init, see https://github.com/MaskRay/ccls/blob/master/src/main.cc#L48

what I need is a global way to set it I've try to set in cpp_ccls_init_options but it didn't work.

not "ccls.index.threads": <number>, but cpp_ccls_init_options={'index':{'threads':1}}
